Technical Details

Zhelatin.TQ does the following upon initial installation:

  • Disables Windows File Protection
  • Drops its rootkit component%SystemDirectory%\diperto[random]-[random].sys
  • Drops its configuration file%SystemDirectory%\diperto.ini
  • Exits the current process

To enable execution of startup, the loader component will create a Windows service to automatically execute the driver on next reboot resulting in the addition of the following registry keys / sub keys in:

  • HKLM\System\CurrentControlSet\Services\diperto[random]-[random]

The malware then tries to communicate with the other peers via the Overnet P2P protocol on how to proceed. It is basically downloading other component/configuration details via the P2P network. The malware has the ability to do the following:

  • Harvest email addresses but avoid those that contain certain strings
  • Download messages to be used in spam
  • Send spam emails
