A Chinese hacking group accused this February of being tied to the Chinese army was caught last December infiltrating a decoy water control system for a U.S. municipality, a researcher revealed on Wednesday.
The group, known as APT1, was caught by a research project that provides the most significant proof yet that people are actively trying to exploit the vulnerabilities in industrial control systems. Many of these systems are connected to the Internet to allow remote access (see “Hacking Industrial Systems Turns Out to Be Easy”). APT1, also known as Comment Crew, was lured by a dummy control system set up by Kyle Wilhoit, a researcher with security company Trend Micro, who gave a talk on his findings at the Black Hat conference in Las Vegas.
The attack began in December 2012, says Wilhoit, when a Word document hiding malicious software was used to gain full access to his U.S.-based decoy system, or “honeypot.” The malware used, and other characteristics, were unique to APT1, which security company Mandiant has claimed operates as part of China’s army (see “Exposé of Chinese Data Thieves Reveals Sloppy Tactics”).
