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.

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.
