Agent Trojan targets Asian gamers

Online security firm ESET has warned of a new Trojan targeting online gamers in Asia.

Win32/PSW.Agent.NDP accounted for 5.73 per cent of the detections made by ESET's ThreatSense.Net tool, which reports detection statistics from millions of client computers around the world.

The program steals information from several sources, before sending the data back to a remote attacker.

"Agent.NDP is an interesting threat as it does not exploit any security vulnerability and does not contain its own mailing engine," said Pierre Marc Bureau, a researcher at ESET.

"Trojans are commonly used to perform identity theft and other malicious actions. Agent.NDP seems to target Chinese online gamers in an attempt to steal information such as usernames and passwords."

ESET explained that the Trojan is probably installed after being downloaded from a website, almost certainly under the guise of another application.

Agent.NDP then copies itself into the victim's temporary folder and writes a DLL in the same folder. It then injects the DLL code into explorer.exe to monitor system execution and find vulnerable information.

ESET's second highest ranking threat for October was INF/Autorun, accounting for 3.45 per cent of all detections.

INF/Autorun describes a variety of malware that uses the autorun.inf file which contains information to run programs automatically when removable media are inserted into a computer.
