BlackTech is a China-linked cyberespionage group active since at least 2011, primarily targeting organizations in Taiwan, with additional operations against Japan, Hong Kong, and the United States. Its targets include technology companies, government agencies, financial institutions, and healthcare organizations. Known aliases include Canary Typhoon, Circuit Panda, Palmerworm, Huapi, Temp.Overboard, Radio Panda, and T-APT-03. Its operations focus on stealing sensitive organizational and government information. BlackTech gains access through spearphishing attachments, links to cloud-hosted malware, and exploitation of public-facing applications. Document-based attacks have exploited Microsoft Office vulnerabilities, including CVE-2018-0802 and CVE-2017-11882. The group has also exploited CVE-2017-7269 in Microsoft IIS 6.0 to establish command-and-control infrastructure and CVE-2020-1938 during an intrusion into a Taiwanese academic institution. It scans for vulnerable routers and abuses compromised network devices and servers for malware delivery and command-and-control relays. Its malware portfolio includes PLEAD, TSCookie, Gh0stTimes, and Linux or Unix variants of its backdoors. PLEAD supports system reconnaissance, saved-credential theft, remote command execution, and file transfer. The associated DRIGO tool collects documents and exfiltrates them through cloud storage. Gh0stTimes adds proxying and relay capabilities to a customized Gh0st RAT foundation. BlackTech has also been associated with the Waterbear and Shrouded Crossbow campaigns. Waterbear supports modular payload deployment, persistent access, and lateral movement. Defense-evasion techniques include DLL side-loading, encrypted payloads and communications, in-memory shellcode execution, process injection, misleading document presentation, and frequently modified malware wrappers. The group maintains tooling for both Windows and Linux environments.
