Technical Details

Trojan-Dropper:W32/Agent.PR drops and executes files on the infected computer. It also creates files in the Windows directory.

On execution, this malware will drop the following files in the %system% folder

• %system%\drivers\npf.sys - Clean
• %system%\Packet.dll - Clean
• %system%\WanPacket.dll - Clean
• %system%\wpcap.dll - Clean
• %system%\systemm.exe - Malware

Note:%system% is the C:\WINDOWS\System32 folder.

It will then execute the file SYSTEMM.EXE that is already detected as Backdoor.Win32.Agent.alh.

It will also create a batch file $$a.bat on the current directory for the sole purpose of deleting the malware dropper and the batch file itself.
