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.

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.

Report: Everyone Should Get a Security Freeze

This author has frequently urged readers to place a security freeze on their credit files as a means of proactively preventing identity theft. Now, a major consumer advocacy group is recommending the same: The U.S. Public Interest Research Group (US-PIRG) recently issued a call for all consumers to request credit file freezes before becoming victims of ID theft.

everyonegetsafreeze

Each time news of a major data breach breaks, the hacked organization arranges free credit monitoring for all customers potentially at risk from the intrusion. But as I’ve echoed time and again, credit monitoring services do little if anything to stop thieves from stealing your identity. The best you can hope for from these services is that they will alert you when a thief opens or tries to open a new line of credit in your name.

But with a “security freeze” on your credit file at the four major credit bureaus, creditors won’t even be able to look at your file in order to grant that phony new line of credit to ID thieves.

Thankfully, US-PIRG — the federation of state public interest research groups — also is now recommending that consumers file proactive security freezes on their credit files.

“These constant breaches reveal what’s wrong with data security and data breach response. Agencies and companies hold too much information for too long and don’t protect it adequately,” the organization wrote in a report (PDF) issued late last month. “Then, they might wait months or even years before informing victims. Then, they make things worse by offering weak, short-term help such as credit monitoring services.”

The report continues: “Whether your personal information has been stolen or not, your best protection against someone opening new credit accounts in your name is the security freeze (also known as the credit freeze), not the often-offered, under-achieving credit monitoring. Paid credit monitoring services in particular are not necessary because federal law requires each of the three major credit bureaus to provide a free credit report every year to all customers who request one. You can use those free reports as a form of do-it-yourself credit monitoring.”

Check out the USPIRG’s full report, Why You Should Get Security Freezes Before Your Information is Stolen (PDF) for more good advice. In case anything in that report is unclear, in June I posted a Q&A on security freezes, explaining how they work, how to place them and the benefits and potential drawbacks of placing a freeze.

Have you frozen your credit file? If so, sound off about the experience in the comments. If not, why not?

OPM (Mis)Spends $133M on Credit Monitoring

The Office of Personnel Management (OPM) has awarded a $133 million contract to a private firm in an effort to provide credit monitoring services for three years to nearly 22 million people who had their Social Security numbers and other sensitive data stolen by cybercriminals. But perhaps the agency should be offering the option to pay for the cost that victims may incur in “freezing” their credit files, a much more effective way of preventing identity theft.

Not long after news broke that Chinese hackers had stolen SSNs and far more sensitive data on 4.2 million individuals — including background investigations, fingerprint data, addresses, medical and mental-health history, and financial history — OPM announced it had awarded a contract worth more than $20 million to Austin, Texas-based identity protection firm CSID to provide 18 months of protection for those affected.

Soon after the CSID contract was awarded, the OPM acknowledged that the breach actually impacted more than five times as many individuals as originally thought. In response, the OPM has awarded a $133 million contract to Portland, Ore. based ID Experts.

No matter how you slice it, $133 million is a staggering figure for a service that in all likelihood will do little to prevent identity thieves from hijacking the names, good credit and good faith of breach victims. While state-sponsored hackers thought to be responsible for this breach were likely interested in the data for more strategic than financial reasons (recruiting, discovering and/or thwarting spies), the OPM should not force breach victims to pay for true protection.

As I’ve noted in story after story, identity protection services like those offered by CSID, Experian and others do little to block identity theft: The most you can hope for from these services is that they will notify you after crooks have opened a new line of credit in your name. Where these services do excel is in helping with the time-consuming and expensive process of cleaning up your credit report with the major credit reporting agencies.

Many of these third party services also induce people to provide even more information than was leaked in the original breach. For example, CSID offers the ability to “monitor thousands of websites, chat rooms, forums and networks, and alerts you if your personal information is being bought or sold online.” But in order to use this service, users are encouraged to provide bank account and credit card data, passport and medical ID numbers, as well as telephone numbers and driver’s license information.

The only step that will reliably block identity thieves from accessing your credit file — and therefore applying for new loans, credit cards and otherwise ruining your good name — is freezing your credit file with the major credit bureaus. This freeze process — described in detail in the primer, How I Learned to Stop Worrying and Embrace the Security Freeze — can be done online or over the phone. Each bureau will give the consumer a unique personal identification number (PIN) that the consumer will need to provide in the event that he needs to apply for new credit in the future.

But there’s a catch: Depending on the state in which you reside, the freeze can cost $5 to $15 per credit bureau. Also, in some states consumers can be charged a fee to temporarily lift the freeze.

It is true that most states allow consumers who can show they have been or are likely to be a victim of ID theft to obtain the freezes for free, but this generally requires the consumer to file a police report, obtain and mail a copy of that report along with photocopied identity documents, and submit an affidavit swearing that the victim believes his or her statement about identity theft to be true.

Unsurprisingly, many who seek the comprehensive protection offered by a freeze in the wake of a breach are more interested in securing the freeze than they are untangling a huge knot of red tape, and so they pay the freeze fees and get on with their lives.

The OPM’s advisory on this breach includes the same boilerplate advice sent to countless victims in other breaches, including the admonition to monitor’s one’s financial statements carefully, to obtain a free copy of one’s credit report from annualcreditreport.com, and to consider filing a free and/or fraud alert with the three major credit bureaus. Nowhere does the agency mention the availability or merits of establishing a security freeze.

If you were affected by the OPM breach, or if you’re interested in learning more about what you can do to protect your identity, please read this story.

Update, 2:30 p.m. ET: Identity Theft Guard Solutions LLC was the original, founding name of ID Experts, the Portland-based company that won the $133 million contract from the OPM. The story above has been changed to include the new name.
