Who’s Behind It?
APT1, also known as Unit 61398 or the Comment Crew, is a cyber espionage group linked to China’s People’s Liberation Army (PLA) General Staff Department’s (GSD) 3rd Department. Operating under the Military Unit Cover Designator (MUCD) of Unit 61398, this group is one of the most notorious and well-documented Chinese cyber operations teams. If your organization operates in sectors critical to national security or economic stability, APT1 could be targeting your most valuable data.
What’s Their Mission?
APT1 has systematically stolen hundreds of terabytes of data from at least 141 organizations across a wide range of industries. Their primary mission is to acquire information that can bolster China’s strategic goals, spanning from technological advancements to military superiority. APT1’s operations are extensive, targeting organizations in English-speaking countries and across sectors like Information Technology, Aerospace, Telecommunications, Energy, Healthcare, and more. The sheer size and scope of their infrastructure suggest a large, well-resourced organization with potentially hundreds of operators working simultaneously.
Their Arsenal
APT1 employs a vast array of custom-developed malware, including TROJAN.ECLTYS, BACKDOOR.BARKIOFORK, BACKDOOR.WAKEMINAP, and others. While they occasionally use publicly available tools like Poison Ivy and Gh0st RAT, their preference is for custom backdoors specifically designed to infiltrate and persist within target networks. APT1’s strategy is to continuously deploy new backdoors as they compromise additional systems, ensuring they maintain access even if one entry point is discovered and removed. This approach allows them to embed deeply within a network, often remaining undetected for years.
How They Get In
The most common method of initial compromise used by APT1 is spear phishing. These emails are tailored to appear relevant to the recipient, often containing a malicious attachment or a hyperlink to a harmful file. APT1 is known for creating webmail accounts using real individuals' names to enhance the credibility of their phishing attempts. Once inside, they spread across the network, deploying multiple backdoors to maintain a persistent presence. Their ability to install new backdoors continuously ensures that they can stay hidden and operational even when parts of their infrastructure are discovered.
