Technical Details


This malware does not appear to be a direct security threat, although it installs itself into the system without asking for any kind of permission from the user. Most of the malware's textual content is encrypted by means of the Cryptography API provided by Windows. The Cryptographic Service Provider used is "Microsoft Base Cryptographic Provider v1.0", and the encryption algorithm used is RSA. Of course, the decryption Key lies within the program's code, which renders the obfuscation attempt almost useless.

Installation to system

It will copy itself into the Windows' System folder as any of the following:

p4mx4.exe  audioinf.exe  kbddrv32.exe  svcinfo.exe  msurl32.exe  mswave.exe  enhance32.exe  helpex32.exe  main32.exe  vidcntl.exe   

And will add an entry in the registry at:

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]   

Which will be named as the filename dropped (without the extension) and point to the executable.
