Cabrotor is backdoor, allowing an attacker to control the machine where it runs. The trojan itself is a Windows PE EXE file written in Delphi.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest detection database updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
NOTE If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note You need administrative rights to change the settings.
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:
The registry key entries it creates are located in:
And their names are:
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
