Summary
We received several reports about a suspicious German message with an attached ZIP archive on May 24th, 2006. The archive contained a trojan dropper for a new variant of a stealthy HaxSpy spying trojan.
Removal
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 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.
Technical Details
The message that the trojan dropper was spreading with looks like the following:
Subject: Betrag uberwiesen Body: Hallo, wie gestern abgesprochen habe ich den Betrag 1967, 83 auf dein Konto berwiesen. Ich denke, das Geld muss schon bermorgen bei Dir sein. Im Anhang habe ich den gescannten Nachweis angeheftet. Ich hoffe, da alle Daten korrekt sind. Bitte gebe mir kurz Bescheid. Lieber Gru Attachment: hc.zip
The ZIP archive contains an executable file with the hc.exe name. This file is the dropper for the two HaxSpy trojan components.
After the trojan's file is run, it drops 2 files to the Windows System folder:
- nkgfs.sys
- nkunpack.dll
The SYS file is a rootkit driver that hides the trojan's files and the DLL file is the main spying component. It is registered as a system component (Winlogon\Notify entry in the Registry) and, being active, collects the following information and sends it back to the hacker:
- Inetcomm server passwords
- POP and IMAP server names, logins and passwords
- The Bat passwords
- Internet Explorer Protected Storage passwords
The trojan modifies Windows firewall settings and blocks access to the following websites:
