Bookworm Linked to Stately Taurus — Unit 42 Analysis

🔎 This Unit 42 case study applies the Unit 42 Attribution Framework to link the Bookworm remote access Trojan to the Chinese APT group Stately Taurus by combining malware analysis, tooling, OPSEC, infrastructure, victimology, and timelines. Analysts highlighted embedded PDB paths, a UUID-based shellcode encoding technique, and co-occurrence with a custom tool named ToneShell. Overlapping C2 IPs and domains, consistent targeting in Southeast Asia, and closely aligned compile times supported a high-confidence attribution. Palo Alto Networks also lists protections across WildFire, NGFW, URL/DNS filtering, Cortex XDR, and incident response contact options.

Operation Rewrite: BadIIS SEO Poisoning Campaign in Asia

🔍 Unit 42 uncovered Operation Rewrite, a March 2025 SEO poisoning campaign that deploys a native IIS implant called BadIIS to manipulate search engine indexing and redirect users to attacker-controlled scam sites. The implant registers request handlers, inspects User‑Agent and Referer headers, and proxies malicious content from remote C2 servers. Variants include lightweight ASP.NET page handlers, a managed .NET IIS module, and an all-in-one PHP front controller. Organizations can detect and block activity with Palo Alto Networks protections and should engage incident responders if compromised.

AdaptixC2: Open-Source Post-Exploitation Framework Used

🛡️ Unit 42 observed AdaptixC2 in early May 2025 being used in real-world intrusions to perform command execution, file transfers and data exfiltration. The open-source framework offers modular beacons, in-memory execution and multiple persistence and tunneling options, which adversaries have adapted for evasive operations. Unit 42 published extraction tools, YARA rules and hunting guidance to help defenders detect and mitigate these threats.
