Today Kaspersky Lab’s team ofexperts published a detailed research report that analyzes a sustainedcyberespionage campaign conducted by the cybercriminal organization known as“Winnti.” According to Kaspersky Lab’sreport, the Winnti group has been attacking companies in the online gamingindustry since 2009 and is currently still active. The group’s objectives arestealing digital certificates signed by legitimate software vendors in additionto intellectual property theft, including the source code of online gameprojects. The first incident that drewattention to the Winnti group’s malicious activities occurred in the autumn of2011, when a malicious Trojan was detected on a large number of end-usercomputers across the globe. The clear link between all of the infectedcomputers is that that they were used to play a popular online game. Shortlyafter the incident, details emerged that the malicious program which hadinfected the users’ computers was part of a regular update from the gaming company’s official server. Infected users and members of the gaming community suspectedthe computer game publisher was installing the malware to spy on its customers. However, it later became clear that the malicious program was installed on the players’ computers byaccident, and that the cybercriminals were actually targeting the computer gamecompany itself. In response, the computer gamepublisher that owned the servers which spread the Trojan to its users askedKaspersky Lab to analyze the malicious program. The Trojan turned out to be aDLL library compiled for a 64-bit Windows environment and used a properlysigned malicious drive. It was a fully functionally Remote Administration Tool(RAT), which gives attackers the ability to control a victim’s computer without the user’s knowledge.
