Technical Details

The original trojan package contains three main executable files:

CaBrONaToR.exe - client to send commands to remote server CaBrONeDiT.exe - server editor to modify default server settings 8======D.exe - server (trojan itself)

When run, the backdoor code copies itself to the Windows directory and registers itself in the system registry in the auto-run section. In different backdoor versions the backdoor EXE name and registry keys are different. The known variant has:

Executable name:

ASDAPI.EXE

The registry key entries it creates are located in:

[HKLM\Software\Microsoft\Windows\CurrentVersion\Run] [HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices]

And their names are:

LoadPowerProfile

The trojan then opens a connection to its master's IRC channel and waits for its master's commands.

The backdoor allows the attacker to invoke any of the following commands:

Reports computer information (Windows version, CPU type, UserName, CompanyName) Open/closes CD drive Reports directories and file names Runs a local file or command Send information: RAS, MS Messenger and .NET services Exits Windows Downloads a requested file Performs DoS attack to a requested victim address Terminates itself
