An alert reader recently pointed my attention to a free online service offered by big-three credit bureau Experian that allows anyone to request the personal identification number (PIN) needed to unlock a consumer credit file that was previously frozen at Experian.

Experian's page for retrieving someone's credit freeze PIN requires little more information than has already been leaked by big-three bureau Equifax and a myriad other breaches.

Experian’s page for retrieving someone’s credit freeze PIN requires little more information than has already been leaked by big-three bureau Equifax and a myriad other breaches.

The first hurdle for instantly revealing anyone’s freeze PIN is to provide the person’s name, address, date of birth and Social Security number (all data that has been jeopardized in breaches 100 times over — including in the recent Equifax breach — and that is broadly for sale in the cybercrime underground).

After that, one just needs to input an email address to receive the PIN and swear that the information is true and belongs to the submitter. I’m certain this warning would deter all but the bravest of identity thieves!

The final authorization check is that Experian asks you to answer four so-called “knowledge-based authentication” or KBA questions. As I have noted in countless stories published here previously, the problem with relying on KBA questions to authenticate consumers online is that so much of the information needed to successfully guess the answers to those multiple-choice questions is now indexed or exposed by search engines, social networks and third-party services online — both criminal and commercial.

What’s more, many of the companies that provide and resell these types of KBA challenge/response questions have been hacked in the past by criminals that run their own identity theft services.

“Whenever I’m faced with KBA-type questions I find that database tools like Spokeo, Zillow, etc are my friend because they are more likely to know the answers for me than I am,” said Nicholas Weaver, a senior researcher in networking and security for the International Computer Science Institute (ICSI).

The above quote from Mr. Weaver came in a story from May 2017 which looked at how identity thieves were able to steal financial and personal data for over a year from TALX, an Equifax subsidiary that provides online payroll, HR and tax services. Equifax says crooks were able to reset the 4-digit PIN given to customer employees as a password and then steal W-2 tax data after successfully answering KBA questions about those employees.

In short: Crooks and identity thieves broadly have access to the data needed to reliably answer KBA questions on most consumers. That is why this offering from Experian completely undermines the entire point of placing a freeze. 

After discovering this portal at Experian, I tried to get my PIN, but the system failed and told me to submit the request via mail. That’s fine and as far as I’m concerned the way it should be. However, I also asked my followers on Twitter who have freezes in place at Experian to test it themselves. More than a dozen readers responded in just a few minutes, and most of them reported success at retrieving their PINs on the site and via email after answering the KBA questions.

Here’s a sample of the KBA questions the site asked one reader:

1. Please select the city that you have previously resided in.

2. According to our records, you previously lived on (XXTH). Please choose the city from the following list where this street is located.

3. Which of the following people live or previously lived with you at the address you provided?

4. Please select the model year of the vehicle you purchased or leased prior to July 2017 .

Experian will display the freeze PIN on its site, and offer to send it to an email address of your choice.

I understand if people who place freezes on their credit files are prone to misplacing the PIN provided by the bureaus that is needed to unlock or thaw a freeze. This is human nature, and the bureaus should absolutely have a reliable process to recover this PIN. However, the information should be sent via snail mail to the address on the credit record, not via email to any old email address.

This is yet another example of how someone or some entity other than the credit bureaus needs to be in put in charge of rethinking and rebuilding the process by which consumers apply for and manage credit freezes. I addressed some of these issues — as well as other abuses by the credit reporting bureaus — in the second half of a long story published Wednesday evening.

Experian has not yet responded to requests for comment.

While this service is disappointing, I stand by my recommendation that everyone should place a freeze on their credit files. I published a detailed Q&A a few days ago about why this is so important and how you can do it.

Krebs on Security 2017-09-20 23:35:26

Bloomberg published a story this week citing three unnamed sources who told the publication that Equifax experienced a breach earlier this year which predated the intrusion that the big-three credit bureau announced on Sept. 7. To be clear, this earlier breach at Equifax is not a new finding and has been a matter of public record for months. Furthermore, it was first reported on this Web site in May 2017.

equihaxIn my initial Sept. 7 story about the Equifax breach affecting more than 140 million Americans, I noted that this was hardly the first time Equifax or another major credit bureau has experienced a breach impacting a significant number of Americans.

On May 17, KrebsOnSecurity reported that fraudsters exploited lax security at Equifax’s TALX payroll division, which provides online payroll, HR and tax services.

That story was about how Equifax’s TALX division let customers who use the firm’s payroll management services authenticate to the service with little more than a 4-digit personal identification number (PIN).

Identity thieves who specialize in perpetrating tax refund fraud figured out that they could reset the PINs of payroll managers at various companies just by answering some multiple-guess questions — known as “knowledge-based authentication” or KBA questions — such as previous addresses and dates that past home or car loans were granted.

On Tuesday, Sept. 18, Bloomberg ran a piece with reporting from no fewer than five journalists there who relied on information provided by three anonymous sources. Those sources reportedly spoke in broad terms about an earlier breach at Equifax, and told the publication that these two incidents were thought to have been perpetrated by the same group of hackers.

The Bloomberg story did not name TALX. Only post-publication did Bloomberg reporters update the piece to include a statement from Equifax saying the breach was unrelated to the hack announced on Sept. 7, and that it had to do with a security incident involving a payroll-related service during the 2016 tax year.

I have thus far seen zero evidence that these two incidents are related. Equifax has said the unauthorized access to customers’ employee tax records (we’ll call this “the March breach” from here on) happened between April 17, 2016 and March 29, 2017.

The criminals responsible for unauthorized activity in the March breach were participating in an insidious but common form of cybercrime known as tax refund fraud, which involves filing phony tax refund requests with the IRS and state tax authorities using the personal information from identity theft victims.

My original report on the March breach was based on public breach disclosures that Equifax was required by law to file with several state attorneys general.

Because the TALX incident exposed the tax and payroll records of its customers’ employees, the victim customers were in turn required to notify their employees as well. That story referenced public breach disclosures from five companies that used TALX, including defense contractor giant Northrop Grumman; staffing firm Allegis GroupSaint-Gobain Corp.; Erickson Living; and the University of Louisville.

When asked Tuesday about previous media coverage of the March breach, Equifax pointed National Public Radio (NPR) to coverage in KrebsonSecurity.

One more thing before I move on to the analysis. For more information on why KBA is a woefully ineffective method of stopping fraudsters, see this story from 2013 about how some of the biggest vendors of these KBA questions were all hacked by criminals running an identity theft service online.

Or, check out these stories about how tax refund fraudsters used weak KBA questions to steal personal data on hundreds of thousands of taxpayers directly from the Internal Revenue Service‘s own Web site. It’s probably worth mentioning that Equifax provided those KBA questions as well.

ANALYSIS

Over the past two weeks, KrebsOnSecurity has received an unusually large number of inquiries from reporters at major publications who were seeking background interviews so that they could get up to speed on Equifax’s spotty security history (sadly, Bloomberg was not among them).

These informational interviews — in which I agree to provide context and am asked to speak mainly on background — are not unusual; I sometimes field two or three of these requests a month, and very often more when time permits. And for the most part I am always happy to help fellow journalists make sure they get the facts straight before publishing them.

But I do find it slightly disturbing that there appear to be so many reporters on the tech and security beats who apparently lack basic knowledge about what these companies do and their roles in perpetuating — not fighting — identity theft.

It seems to me that some of the world’s most influential publications have for too long given Equifax and the rest of the credit reporting industry a free pass — perhaps because of the complexities involved in succinctly explaining the issues to consumers. Indeed, I would argue the mainstream media has largely failed to hold these companies’ feet to the fire over a pattern of lax security and a complete disregard for securing the very sensitive consumer data that drives their core businesses.

To be sure, Equifax has dug themselves into a giant public relations hole, and they just keep right on digging. On Sept. 8, I published a story equating Equifax’s breach response to a dumpster fire, noting that it could hardly have been more haphazard and ill-conceived.

But I couldn’t have been more wrong. Since then, Equifax’s response to this incident has been even more astonishingly poor.

EQUIPHISH

On Tuesday, the official Equifax account on Twitter replied to a tweet requesting the Web address of the site that the company set up to give away its free one-year of credit monitoring service. That site is https://www.equifaxsecurity2017.com, but the company’s Twitter account told users to instead visit securityequifax2017[dot]com, which is currently blocked by multiple browsers as a phishing site.

FREEZING UP

Under intense public pressure from federal lawmakers and regulators, Equifax said that for 30 days it would waive the fee it charges for placing a security freeze on one’s credit file (for more on what a security freeze entails and why you and your family should be freezing their files, please see The Equifax Breach: What You Should Know).

Unfortunately, the free freeze offer from Equifax doesn’t mean much if consumers can’t actually request one via the company’s freeze page; I have lost count of how many comments have been left here by readers over the past week complaining of being unable to load the site, let alone successfully obtain a freeze. Instead, consumers have been told to submit the requests and freeze fees in writing and to include copies of identity documents to validate the requests.

Sen. Elizabeth Warren (D-Mass) recently introduced a measure that would force the bureaus to eliminate the freeze fees and to streamline the entire process. To my mind, that bill could not get passed soon enough.

Understand that each credit bureau has a legal right to charge up to $20 in some states to freeze a credit file, and in many states they are allowed to charge additional fees if consumers later wish to lift or temporarily thaw a freeze. This is especially rich given that credit bureaus earn roughly $1 every time a potential creditor (or identity thief) inquires about your creditworthiness, according to Avivah Litan, a fraud analyst with Gartner Inc.

In light of this, it’s difficult to view these freeze fees as anything other than a bid to discourage consumers from filing them.

The Web sites where consumers can go to file freezes at the other major bureaus — including TransUnion and Experian — have hardly fared any better since Equifax announced the breach on Sept. 7. Currently, if you attempt to freeze your credit file at TransUnion, the company’s site is relentless in trying to steer you away from a freeze and toward the company’s free “credit lock” service.

That service, called TrueIdentity, claims to allow consumers to lock or unlock their credit files for free as often as they like with the touch of a button. But readers who take the bait probably won’t notice or read the terms of service for TrueIdentity, which has the consumer agree to a class action waiver, a mandatory arbitration clause, and something called ‘targeted marketing’ from TransUnion and their myriad partners.

The agreement also states TransUnion may share the data with other companies:

“If you indicated to us when you registered, placed an order or updated your account that you were interested in receiving information about products and services provided by TransUnion Interactive and its marketing partners, or if you opted for the free membership option, your name and email address may be shared with a third party in order to present these offers to you. These entities are only allowed to use shared information for the intended purpose only and will be monitored in accordance with our security and confidentiality policies. In the event you indicate that you want to receive offers from TransUnion Interactive and its marketing partners, your information may be used to serve relevant ads to you when you visit the site and to send you targeted offers.  For the avoidance of doubt, you understand that in order to receive the free membership, you must agree to receive targeted offers.

TransUnion then encourages consumers who are persuaded to use the “free” service to subscribe to “premium” services for a monthly fee with a perpetual auto-renewal.

In short, TransUnion’s credit lock service (and a similarly named service from Experian) doesn’t prevent potential creditors from accessing your files, and these dubious services allow the credit bureaus to keep selling your credit history to lenders (or identity thieves) as they see fit.

As I wrote in a Sept. 11 Q&A about the Equifax breach, I take strong exception to the credit bureaus’ increasing use of the term “credit lock” to divert people away from freezes. Their motives for saddling consumers with even more confusing terminology are suspect, and I would not count on a credit lock to take the place of a credit freeze, regardless of what these companies claim (consider the source).

Experian’s freeze Web site has performed little better since Sept. 7. Several readers pinged KrebsOnSecurity via email and Twitter to complain that while Experian’s freeze site repeatedly returned error messages stating that the freeze did not go through, these readers’ credit cards were nonetheless charged $15 freeze fees multiple times.

If the above facts are not enough to make your blood boil, consider that Equifax and other bureaus have been lobbying lawmakers in Congress to pass legislation that would dramatically limit the ability of consumers to sue credit bureaus for sloppy security, and cap damages in related class action lawsuits to $500,000.

If ever there was an industry that deserved obsolescence or at least more regulation, it is the credit bureaus. If either of those outcomes are to become reality, it is going to take much more attentive and relentless coverage on the part of the world’s top news publications. That’s because there’s a lot at stake here for an industry that lobbies heavily (and successfully) against any new laws that may restrict their businesses.

Here’s hoping the media can get up to speed quickly on this vitally important topic, and help lead the debate over legal and regulatory changes that are sorely needed.

Sep 11 2017

Krebs on Security 2017-09-11 20:31:40

It remains unclear whether those responsible for stealing Social Security numbers and other data on as many as 143 million Americans from big-three credit bureau Equifax intend to sell this data to identity thieves. But if ever there was a reminder that you — the consumer — are ultimately responsible for protecting your financial future, this is it. Here’s what you need to know and what you should do in response to this unprecedented breach.

Some of the Q&As below were originally published in a 2015 story, How I Learned to Stop Worrying and Embrace the Security Freeze. It has been updated to include new information specific to the Equifax intrusion.

Q: What information was jeopardized in the breach?

A: Equifax was keen to point out that its investigation is ongoing. But for now, the data at risk includes Social Security numbers, birth dates, addresses on 143 million Americans. Equifax also said the breach involved some driver’s license numbers (although it didn’t say how many or which states might be impacted), credit card numbers for roughly 209,000 U.S. consumers, and “certain dispute documents with personal identifying information for approximately 182,000 U.S. consumers.”

Q: Was the breach limited to Americans?

A: No. Equifax said it believes the intruders got access to “limited personal information for certain UK and Canadian residents.” It has not disclosed what information for those residents was at risk or how many from Canada and the UK may be impacted.

Q: What is Equifax doing about this breach?

A: Equifax is offering one free year of their credit monitoring service. In addition, it has put up a Web site — www.equifaxsecurity2017.com — that tried to let people determine whether they were affected.

Q: That site tells me I was not affected by the breach. Am I safe?

A: As noted in this story from Friday, the site seems hopelessly broken, often returning differing results for the same data submitted at different times. In the absence of more reliable information from Equifax, it is safer to assume you ARE compromised.

Q: I read that the legal language in the terms of service that consumers must accept before enrolling in the free credit monitoring service from Equifax requires one to waive their rights to sue the company in connection with this breach. Is that true?

A: Not according to Equifax. The company issued a statement over the weekend saying that nothing in that agreement applies to this cybersecurity incident.

Q: So should I take advantage of the credit monitoring offer?

A: It can’t hurt, but I wouldn’t count on it protecting you from identity theft.

Q: Wait, what? I thought that was the whole point of a credit monitoring service?

A: The credit bureaus sure want you to believe that, but it’s not true in practice. These services do not prevent thieves from using your identity to open new lines of credit, and from damaging your good name for years to come in the process. The most you can hope for is that credit monitoring services will alert you soon after an ID thief does steal your identity.

Q: Well then what the heck are these services good for?

A: Credit monitoring services are principally useful in helping consumers recover from identity theft. Doing so often requires dozens of hours writing and mailing letters, and spending time on the phone contacting creditors and credit bureaus to straighten out the mess. In cases where identity theft leads to prosecution for crimes committed in your name by an ID thief, you may incur legal costs as well. Most of these services offer to reimburse you up to a certain amount for out-of-pocket expenses related to those efforts. But a better solution is to prevent thieves from stealing your identity in the first place.

Q: What’s the best way to do that?

A: File a security freeze — also known as a credit freeze — with the four major credit bureaus.

Q: What is a security freeze?

A: A security freeze essentially blocks any potential creditors from being able to view or “pull” your credit file, unless you affirmatively unfreeze or thaw your file beforehand. With a freeze in place on your credit file, ID thieves can apply for credit in your name all they want, but they will not succeed in getting new lines of credit in your name because few if any creditors will extend that credit without first being able to gauge how risky it is to loan to you (i.e., view your credit file). And because each credit inquiry caused by a creditor has the potential to lower your credit score, the freeze also helps protect your score, which is what most lenders use to decide whether to grant you credit when you truly do want it and apply for it.

Q: What’s involved in freezing my credit file?

A: Freezing your credit involves notifying each of the major credit bureaus that you wish to place a freeze on your credit file. This can usually be done online, but in a few cases you may need to contact one or more credit bureaus by phone or in writing. Once you complete the application process, each bureau will provide a unique personal identification number (PIN) that you can use to unfreeze or “thaw” your credit file in the event that you need to apply for new lines of credit sometime in the future. Depending on your state of residence and your circumstances, you may also have to pay a small fee to place a freeze at each bureau. There are four consumer credit bureaus, including EquifaxExperianInnovis and Trans Union.  It’s a good idea to keep your unfreeze PIN(s) in a folder in a safe place (perhaps along with your latest credit report), so that when and if you need to undo the freeze, the process is simple.

Q: How much is the fee, and how can I know whether I have to pay it?

A: The fee ranges from $0 to $15 per bureau, meaning that it can cost upwards of $60 to place a freeze at all four credit bureaus (recommended). However, in most states, consumers can freeze their credit file for free at each of the major credit bureaus if they also supply a copy of a police report and in some cases an affidavit stating that the filer believes he/she is or is likely to be the victim of identity theft. In many states, that police report can be filed and obtained online. The fee covers a freeze as long as the consumer keeps it in place. Consumers Union has a useful breakdown of state-by-state fees.

Q: But what if I need to apply for a loan, or I want to take advantage of a new credit card offer?

A: You thaw the freeze temporarily (in most cases the default is for 24 hours).

Q: What’s involved in thawing my credit file? And do I need to thaw it at all three bureaus?

A: The easiest way to unfreeze your file for the purposes of gaining new credit is to spend a few minutes the phone with the company from which you hope to gain the line of credit (or research the matter online) to see which credit bureau they rely upon for credit checks. It will most likely be one of the major bureaus. Once you know which bureau the creditor uses, contact that bureau either via phone or online and supply the PIN they gave you when you froze your credit file with them. The thawing process should not take more than 24 hours, but hiccups in the thawing process sometimes make things take longer. It’s best not to wait until the last minute to thaw your file.

Q: It seems that credit bureaus make their money by selling data about me as a consumer to marketers. Does a freeze prevent that?

A: A freeze on your file does nothing to prevent the bureaus from collecting information about you as a consumer — including your spending habits and preferences — and packaging, splicing and reselling that information to marketers.

Q: Can I still use my credit or debit cards after I file a freeze? 

A: Yes. A freeze does nothing to prevent you from using existing lines of credit you may have.

Q: I’ve heard about something called a fraud alert. What’s the difference between a security freeze and a fraud alert on my credit file?

A: With a fraud alert on your credit file, lenders or service providers should not grant credit in your name without first contacting you to obtain your approval — by phone or whatever other method you specify when you apply for the fraud alert. To place a fraud alert, merely contact one of the credit bureaus via phone or online, fill out a short form, and answer a handful of multiple-choice, out-of-wallet questions about your credit history. Assuming the application goes through, the bureau you filed the alert with must by law share that alert with the other bureaus.

Consumers also can get an extended fraud alert, which remains on your credit report for seven years. Like the free freeze, an extended fraud alert requires a police report or other official record showing that you’ve been the victim of identity theft.

An active duty alert is another alert available if you are on active military duty. The active duty alert is similar to an initial fraud alert except that it lasts 12 months and your name is removed from pre-approved firm offers of credit or insurance (prescreening) for 2 years.

Q: Why would I pay for a security freeze when a fraud alert is free?

A: Fraud alerts only last for 90 days, although you can renew them as often as you like. More importantly, while lenders and service providers are supposed to seek and obtain your approval before granting credit in your name if you have a fraud alert on your file, they are not legally required to do this — and very often don’t.

Q: Hang on: If I thaw my credit file after freezing it so that I can apply for new lines of credit, won’t I have to pay to refreeze my file at the credit bureau where I thawed it?

A: It depends on your state. Some states allow bureaus to charge $5 for a temporary thaw or a lift on a freeze; in other states there is no fee for a thaw or lift. However, even if you have to do this once or twice a year, the cost of doing so is almost certainly less than paying for a year’s worth of credit monitoring services. Again, Consumers Union has a handy state-by-state guide listing the freeze and unfreeze laws and fees.

Q: What about my kids? Should I be freezing their files as well? Is that even possible? 

A: Depends on your state. Roughly half of the U.S. states have laws on the books allowing freezes for dependents. Check out The Lowdown on Freezing Your Kid’s Credit for more information.

Q: Is there anything I should do in addition to placing a freeze that would help me get the upper hand on ID thieves?

A: Yes: Periodically order a free copy of your credit report. By law, each of the three major credit reporting bureaus must provide a free copy of your credit report each year — via a government-mandated site: annualcreditreport.com. The best way to take advantage of this right is to make a notation in your calendar to request a copy of your report every 120 days, to review the report and to report any inaccuracies or questionable entries when and if you spot them. Avoid other sites that offer “free” credit reports and then try to trick you into signing up for something else.

Q: I just froze my credit. Can I still get a copy of my credit report from annualcreditreport.com? 

A: According to the Federal Trade Commission, having a freeze in place should not affect a consumer’s ability to obtain copies of their credit report from annualcreditreport.com.

Q: If I freeze my file, won’t I have trouble getting new credit going forward? 

A: If you’re in the habit of applying for a new credit card each time you see a 10 percent discount for shopping in a department store, a security freeze may cure you of that impulse. Other than that, as long as you already have existing lines of credit (credit cards, loans, etc) the credit bureaus should be able to continue to monitor and evaluate your creditworthiness should you decide at some point to take out a new loan or apply for a new line of credit.

Q: Can I have a freeze AND credit monitoring? 

A: Yes, you can. However, it may not be possible to sign up for credit monitoring services while a freeze is in place. My advice is to sign up for whatever credit monitoring may be offered for free, and then put the freezes in place.

Q: Beyond this breach, how would I know who is offering free credit monitoring? 

A: Hundreds of companies — many of which you have probably transacted with at some point in the last year — have disclosed data breaches and are offering free monitoring. California maintains one of the most comprehensive lists of companies that disclosed a breach, and most of those are offering free monitoring.

Q: I see that Trans Union has a free offering. And it looks like they offer another free service called a credit lock. Why shouldn’t I just use that?

A: I haven’t used that monitoring service, but it looks comparable to others. However, I take strong exception to the credit bureaus’ increasing use of the term “credit lock” to steer people away from securing a freeze on their file. I notice that Trans Union currently does this when consumers attempt to file a freeze. Your mileage may vary, but their motives for saddling consumers with even more confusing terminology are suspect. I would not count on a credit lock to take the place of a credit freeze, regardless of what these companies claim (consider the source).

Q: I read somewhere that the PIN code Equifax gives to consumers for use in the event they need to thaw a freeze at the bureau is little more than a date and time stamp of the date and time when the freeze was ordered. Is this correct? 

A: Yes. However, this does not appear to be the case with the other bureaus.

Q: Does this make the process any less secure? 

A: Hard to say. An identity thief would need to know the exact time your report was ordered. Unless of course Equifax somehow allowed attackers to continuously guess and increment that number through its Web site (there is no indication this is the case). However, having a freeze is still more secure than not having one.

Q: Someone told me that having a freeze in place wouldn’t block ID thieves from fraudulently claiming a tax refund in my name with the IRS, or conducting health insurance fraud using my SSN. Is this true?

A: Yes. There are several forms of identity theft that probably will not be blocked by a freeze. But neither will they be blocked by a fraud alert or a credit lock. That’s why it’s so important to regularly review your credit file with the major bureaus for any signs of unauthorized activity.

Q: Okay, I’ve got a security freeze on my file, what else should I do?

A: It’s also a good idea to notify a company called ChexSystems to keep an eye out for fraud committed in your name. Thousands of banks rely on ChexSystems to verify customers that are requesting new checking and savings accounts, and ChexSystems lets consumers place a security alert on their credit data to make it more difficult for ID thieves to fraudulently obtain checking and savings accounts. For more information on doing that with ChexSystems, see this link

Q: Anything else?

A: ID thieves like to intercept offers of new credit and insurance sent via postal mail, so it’s a good idea to opt out of pre-approved credit offers. If you decide that you don’t want to receive prescreened offers of credit and insurance, you have two choices: You can opt out of receiving them for five years or opt out of receiving them permanently.

To opt out for five years: Call toll-free 1-888-5-OPT-OUT (1-888-567-8688) or visit www.optoutprescreen.com. The phone number and website are operated by the major consumer reporting companies.

To opt out permanently: You can begin the permanent Opt-Out process online at www.optoutprescreen.com. To complete your request, you must return the signed Permanent Opt-Out Election form, which will be provided after you initiate your online request.

Krebs on Security 2017-09-08 14:15:13

I cannot recall a previous data breach in which the breached company’s public outreach and response has been so haphazard and ill-conceived as the one coming right now from big-three credit bureau Equifax, which rather clumsily announced Thursday that an intrusion jeopardized Social security numbers and other information on 143 million Americans.

WEB SITE WOES

As noted in yesterday’s breaking story on this breach, the Web site that Equifax advertised as the place where concerned Americans could go to find out whether they were impacted by this breach — equifaxsecurity2017.com
is completely broken at best, and little more than a stalling tactic or sham at worst.

In the early hours after the breach announcement, the site was being flagged by various browsers as a phishing threat. In some cases, people visiting the site were told they were not affected, only to find they received a different answer when they checked the site with the same information on their mobile phones.

phonelaptopequifax

Others (myself included) received not a yes or no answer to the question of whether we were impacted, but instead a message that credit monitoring services we were eligible for were not available and to check back later in the month. The site asked users to enter their last name and last six digits of their SSN, but at the prompting of a reader’s comment I confirmed that just entering gibberish names and numbers produced the same result as the one I saw when I entered my real information: Come back on Sept. 13.

Who’s responsible for this debacle? Well, Equifax of course. But most large companies that can afford to do so hire outside public relations or disaster response firms to walk them through the safest ways to notify affected consumers. In this case, Equifax appears to have hired global PR firm Edelman PR.

What gives me this idea? Until just a couple of hours ago, the copy of WordPress installed at equifaxsecurity2017.com included a publicly accessible user database entry showing a user named “Edelman” was the first (and only?) user registered on the site.

Code that was publicly available on equifaxsecurity2017.com until very recently showed account information for an outside PR firm.

I reached out to Edelman for more information and will update this story when I hear from them.

EARLY WARNING?

In its breach disclosure Thursday, Equifax said it hired an outside computer security forensic firm to investigate as soon as it discovered unauthorized access to its Web site. ZDNet published a story Thursday saying that the outside firm was Alexandria, Va.-based Mandiant — a security firm bought by FireEye in 2014.

Interestingly, anyone who happened to have been monitoring look-alike domains for Equifax.com prior to yesterday’s breach announcement may have had an early clue about the upcoming announcement. One interesting domain that was registered on Sept. 5, 2017 is “equihax.com,” which according to domain registration records was purchased by an Alexandria, Va. resident named Brandan Schondorfer.

A quick Google search shows that Schondorfer works for Mandiant. Ray Watson, a cybersecurity researcher who messaged me this morning on Twitter about this curiosity, said it is likely that Mandiant has been registering domains that might be attractive to phishers hoping to take advantage of public attention to the breach and spoof Equifax’s domain.

Watson said it’s equally likely the equihax.com domain was registered to keep it out of the hands of people who may be looking for domain names they can use to lampoon Equifax for its breach. Schondorfer has not yet returned calls seeking comment.

EQUIFAX EXECS PULL GOLDEN PARACHUTES?

Bloomberg moved a story yesterday indicating that three top executives at Equifax sold millions of dollars worth of stock during the time between when the company says it discovered the breach and when it notified the public and investors.

Shares of Equifax’s stock on the New York Stock Exchange [NSYE:EFX] were down more than 13 percent at time of publication versus yesterday’s price.

The executives reportedly told Bloomberg they didn’t know about the breach when they sold their shares. A law firm in New York has already announced it is investigating potential insider trading claims against Equifax.

CLASS ACTION WAIVER?

Yesterday’s story here pointed out the gross conflict of interest in Equifax’s consumer remedy for this breach: Offering a year’s worth of free credit monitoring services to all Americans via its own in-house credit monitoring service.

This is particularly rich because a) why should anyone trust Equifax to do anything right security-wise after this debacle and b) these credit monitoring services typically hard-sell consumers to sign up for paid credit protection plans when the free coverage expires.

Verbiage from the terms of service from Equifax's credit monitoring service TrustID Premier.

I have repeatedly urged readers to consider putting a security freeze on their accounts in lieu of or in addition to accepting these free credit monitoring offers, noting that credit monitoring services don’t protect you against identity theft (the most you can hope for is they alert you when ID thieves do steal your identity), while security freezes can prevent thieves from taking out new lines of credit in your name.

Several readers have written in to point out some legalese in the terms of service the Equifax requires all users to acknowledge before signing up for the service seems to include legal verbiage suggesting that those who do sign up for the free service will waive their rights to participate in future class action lawsuits against the company.

KrebsOnSecurity is still awaiting word from an actual lawyer who’s looking at this contract, but let me offer my own two cents on this.

Update, 9:45 p.m. ET: Equifax has updated their breach alert page to include the following response in regard to the unclear legalese:

“In response to consumer inquiries, we have made it clear that the arbitration clause and class action waiver included in the Equifax and TrustedID Premier terms of use does not apply to this cybersecurity incident.”

Original story:

Equifax will almost certainly see itself the target of multiple class action lawsuits as a result of this breach, but there is no guarantee those lawsuits will go the distance and result in a monetary windfall for affected consumers.

Even when these cases do result in a win for the plaintiff class, it can take years. After KrebsOnSecurity broke the story in 2013 that Experian had given access to 200 million consumer records to Vietnamese man running an identity theft service, two different law firms filed class action suits against Experian.

That case was ultimately tossed out of federal court and remanded to state court, where it is ongoing. That case was filed in 2015.

To close out the subject of civil lawsuits as a way to hold companies accountable for sloppy security, class actions — even when successful — rarely result in much of a financial benefit for affected consumers (very often the “reward” is a gift card or two-digit dollar amount per victim), while greatly enriching law firms that file the suits.

It’s my view that these class action lawsuits serve principally to take the pressure off of lawmakers and regulators to do something that might actually prevent more sloppy security practices in the future for the victim culpable companies. And as I noted in yesterday’s story, the credit bureaus have shown themselves time and again to be terribly unreliable stewards of sensitive consumer data: This time, the intruders were able to get in because Equifax apparently fell behind in patching its Internet-facing Web applications.

In May, KrebsOnSecurity reported that fraudsters exploited lax security at Equifax’s TALX payroll division, which provides online payroll, HR and tax services. In 2015, a breach at Experian jeopardized the personal data on at least 15 million consumers.

CAPITALIZING ON FEAR

Speaking of Experian, the company is now taking advantage of public fear over the breach — via hashtag #equifaxbreach, for example — to sign people up for their cleverly-named “CreditLock” subscription service (again, hat tip to @rayjwatson).

“When you have Experian Identity Theft Protection, you can instantly lock or unlock your Experian Credit File with the simple click of a button,” the ad enthuses. “Experian gives you instant access to your credit report.”

First off, all consumers have the legal right to instant access to their credit report via the Web site, annualcreditreport.com. This site, mandated by Congress, gives consumers the right to one free credit report from each of the three major bureaus (Equifax, Trans Union and Experian) every year.

Second, all consumers have a right to request that the bureaus “freeze” their credit files, which bars potential creditors or anyone else from viewing your credit history or credit file unless you thaw the freeze (temporarily or permanently).

I have made no secret of my disdain for the practice of companies offering credit monitoring in the wake of a data breach — especially in cases where the breach only involves credit card accounts, since credit monitoring services typically only look for new account fraud and do little or nothing to prevent fraud on existing consumer credit accounts.

Credit monitoring services rarely prevent identity thieves from stealing your identity. The most you can hope for from these services is that they will alert you as soon as someone does steal your identity. Also, the services can be useful in helping victims recover from ID theft.

My advice: Sign up for credit monitoring if you can (and you’re not holding out for a puny class action windfall) and then freeze your credit files at the major credit bureaus (it is generally not possible to sign up for credit monitoring services after a freeze is in place). Again, advice for how to file a freeze is available here.

Whether you are considering a freeze, credit monitoring, or a fraud alert (another, far less restrictive third option), please take a moment to read this story in its entirety. It includes a great deal of information that cannot be shared in a short column here.
