Worm Lures Victims with Indian Celebrity Video Links

Malicious worms are found infecting customers through-out the year. They keep evolving to evade the Anti Virus detections. They add junk codes or come up with new custom packer, yet achieve their full functionality and reward their developers.

We have seen earlier how different types of malware use chat windows to download and spread across victims here and here.

This worm spreads by copying itself to removable drives and writeable network shares,and by modifying system settings. It can also send out messages via instant messaging client messages.

Spreading technique:



A file by the name Setting.ini is dropped into Windows system folder. It then tries to download other files from any URL specified randomly and once downloaded they are then executed.

What looked interesting to us was that some messages send by this worm actually had some Indian celebrities’ names like Aishwarya Rai,Nayanthara and Simbufollowed by a link.

The URLs are actually retrieved from setting.ini randomly.URLs point to a remote server which host a copy of worm. The following are few messages seen:

  • ·         “Aishwarya Rai videos ftp://tlpoeil:[email protected] <url>”
  • ·         “stream Video of Nayanthara and Simbu ftp://tlpoeil:[email protected] <url>”
  • ·         “Latest video shot of infosys girl ftp://tlpoeil:[email protected] <url>”
  • “Latest video shot of infosys girl ftp://tlpoeil:[email protected] <url>”
  • ·         “cyber cafe scandal visit ftp://tlpoeil:[email protected] <url>”
  • ·         “World Business news broadcaster ftp://tlpoeil:[email protected] <url>”
  • ·         “Regular monthly income by wearing your shorts at the comfort of your home for more info ftp://tlpoeil:[email protected] <url>”
  • ·         “Nfs carbon download ftp://tlpoeil:[email protected] <url>”
  • ·         “Free mobile games ftp://tlpoeil:[email protected] <url>”
  • “Nse going to crash for more ftp://tlpoeil:[email protected] <url>”

From the look at the list of messages in setting.ini, we suspect this variant of worm was targeted against Indian computer users.

In case if the worm fails to read the content of setting.ini, it send one of the following messages (in Vietnamese) with the URL pointing to remote server hosting the worm.

  • E may, vao day coi co con nho nay ngon lam
  • Vao day nghe bai nay di ban
  • Biet tin gi chua, vao day coi di
  • Trang Web nay coi cung hay, vao coi thu di

The worm also has the ability to enumerate through various applications running in the victim’s machine and terminating if the following were found:

  • “Registry”
  • “System Configuration”
  • “Windows mask”
  • “Bkav2006″
  • “Trung tƒm An ninh m?ng Bkis”
  • “FireLion”

The following system changes can be looked out for checking the presence of this worm:

  • The presence of the following files:
    <system folder>/regsvr.exe
    <system folder>/svchost .exe
    New Folder.exe (with a folder icon)

The dropped files are all sample copies with Folder icon.

  • Taksmgr.exe and Regedit.exe are disabled.
  • AT1.job is created to ensure that the worm gets executed everyday at 9:00 AM.

  • The presence of the following registry modifications:
    HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
    “Shell” = “explorer.exe regsvr.exe”HKCU\Software\Microsoft\Windows\CurrentVersion\Run
    Msn Messsenger” = “<system folder>\regsvr.exe”

We advise our customers to pay extra caution when they plug in their USB sticks and keep their DATS updated.

McAfee detects this worm as W32/Autorun.g.
