Details
Trojan.PSW.GOPTrojan
This program belongs to the family of password stealing Trojans. This Trojan seems to be written in Chinese and is designed to steal OICQ (a Chinese clone of ICQ?) passwords.
When run, the Trojan installs itself to the system. While installing, the Trojan copies itself to Windows, the Windows system or TEMP directory, and registers itself in the system registry auto-run section. For example:
Trojan full name: WINDOWSSYSTEMwinzipauto.exe
Registry key:
HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun WindowsAgent = winzipauto.exe
The installed Trojan file name and the target directory are optional. They are stored in encrypted form in the Trojan file at the file end. To steal OICQ data, the Trojan also drops an additional DLL file (hooker) with an optional name. A hacker may configure optional data before sending the Trojan to a victim's machine, or before placing it on a Web site.
There are other optional features of this Trojan:
displays a decoy (fake) messsage, and the message text
deletes an original file after installing into the system
e-mail address to there stolen data being sent (default - goicq@sina.com)
smtp server to there the data being sent (default - smtp.sina.com.cn)
The Trojan then registers itself in the system as a hidden aplication (service). The Trojan's process then is not visible in the task list. Being active in the system, the Trojan periodically sends e-mail messages to its host (hacker's e-mail address).
There are known "upgrated" versions of this Trojan that don't mail themselves, and are "Internet worms" as a result. See {"GOPworm":IWorm.GOPworm}. |
