What is the Trojan.OnlineGames infection?

The Trojan.OnlineGames family is quite large. Variants in this family are designed to steal confidential information from players of popular online games, such as World of Warcraft.Onlinegame password stealing trojans are designed to steal account information in order to allow a remote hacker access to the player’s account. The hacker can then logon and steal the player’s virtual assets by transferring them to another player account. Such assets are often sold or auctioned off for real-world currency. With millions of players, such trojans can easily affect thousands of users.

Trojan.OnlineGames installs itself to the system by copying its file to Windows folder. It also creates a startup key value in the Registry for the copied file. This is done to make sure that the trojan’s file is started every time Windows boots. The startup key value is created under the following Registry key:
[HKLM\SoftWare\Microsoft\Windows\CurrentVersion\Run]
After installation the trojan locates the Explorer.exe process, drops a DLL from its body onto a hard drive and injects the dropped DLL into the Windows Explorer process. Note that unlike the main trojan’s file, the DLL is dropped into the Windows System folder. The dropped DLL is the main spying component.

In order to retrieve sensitive data, the trojan reads the process memory of certain game executables, for example WOW.EXE (World of Warcraft), ElementClient.exe (Perfect World), CabalMain.exe (Cabal Online). The trojan may also attempt to read certain variables from the games’ configuration files.
For example, the current game server address may be read from the CurrentServer.ini file. Some variants of the trojan have keylogging capabilities. They monitor what keys a user pressed and sends the keyboard activity logs to a malicious hacker.The spying component contains an encrypted URL that is used to send stolen data. The stolen data is sent to a hacker by accessing the specified website with a specially constructed URL. The trojan can also try to connect to a hard-coded IP Address, create a socket and send stolen data to it. Typically many of these IP addresses are registered in China.

How did Trojan.OnlineGames infection got on my computer?

The Trojan.OnlineGames virus is distributed through several means. Malicious websites, or legitimate websites that have been hacked, can infect your machine through exploit kits that use vulnerabilities on your computer to install this Trojan without your permission of knowledge.

Another method used to propagate this type of malware is spam email containing infected attachments or links to malicious websites. Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link embedded inside the email). And with that, your computer is infected with the Trojan.OnlineGames virus.

The threat may also be downloaded manually by tricking the user into thinking they are installing a useful piece of software, for instance a bogus update for Adobe Flash Player or another piece of software.
