Zhengquan Zhang, a 31-year-old IT engineer, is accused of installing malware on his employer’s servers to steal proprietary source code. Zhang was tasked with managing the source code of KCG’s trading platform and the trading algorithms the company used to automate some of its financial transactions. Zhang admitted to planting malware on the company’s servers and remotely accessing the accounts of several other KCG employees, besides the quantitive analyst who initially detected his actions. KCG admins revoked Zhang’s access, called in authorities, and started an official investigation.
