New Malware Tools Detected in Cyberattacks Linked to China Across Asia-Pacific

Recent reports have shed light on sophisticated cyberattacks conducted by the China-linked threat group, BlackTech, targeting various government, research, and technology sectors throughout the Asia-Pacific region. Known under multiple aliases including Earth Hundun, Manga Taurus, Circuit Panda, Temp.Overboard, Palmerwom, Red Djinn, and HUAPI, BlackTech has been actively deploying enhanced malicious tools such as the Waterbear backdoor and its more advanced variant, Deuterbear.

Enhancements to Waterbear and Introduction of Deuterbear

According to a detailed analysis by Trend Micro, the Waterbear backdoor, a longstanding tool in BlackTech’s arsenal, has undergone significant updates. It now supports nearly 50 commands that provide extensive control over the compromised systems, including process termination, window management, and modifications to the Windows Registry. Despite its roots, Deuterbear has evolved into a distinct malware entity, equipped with a downloader that boasts anti-analysis features and HTTPS encryption to secure its network communications.

Advanced Capabilities of Deuterbear

Researchers highlight that Deuterbear marks a substantial advancement in malware execution strategies used by BlackTech. The updated downloader utilizes HTTPS encryption to safeguard its network traffic and incorporates several new techniques designed to enhance its stealth and efficiency. These include alterations in function decryption, mechanisms to detect and evade debuggers or sandboxes, and changes to traffic protocols, underscoring the malware’s sophisticated design aimed at evading detection and analysis.

Global Implications and Warnings

The emergence of these findings follows a joint advisory by U.S. and Japanese cybersecurity and intelligence entities, which previously warned about the extensive and diverse arsenal of attack tools at BlackTech’s disposal. This advisory underscores the ongoing and evolving threats posed by such state-linked cyber espionage groups.
