SilkParasite Uses AI-Assisted RATs in Current Campaign to Target Central Asian Governments

SilkParasite is a cyber espionage campaign targeting government bodies and economic institutions across Central Asia (and one (1) Georgian entity), assessed by Bitdefender with medium confidence as being a China-nexus. In current campaigns, the group is noted to be using seven (7) plugin based remote access tools, five (5) of them previously unseen (DriveSilkRAT, CookiETagRAT, NomadRAT, GoginRAT, and NodeEdgeRAT). Initial access comes via password protected RAR archives carrying malicious Office documents tailored to ministries in Uzbekistan, Turkmenistan, Kyrgyzstan, Tajikistan, Kazakhstan, and Georgia, with macros that trigger DLL sideloading of first stage payloads and check for Kaspersky AV to evade detection. DriveSilkRAT, the most widespread strain (seen in roughly sixty-five (65) infections), uses a shared Google Drive folder as command and control (C2), blending traffic with normal cloud use. Other RATs use HTTP cookies/ETags or modular transmitters and plugins for command execution, file management, and shell access. The toolset also includes BLOODALCHEMY (a ShadowPad/PlugX lineage backdoor) and an improved SpiceRAT, reinforcing the China nexus assessments made by Bitdefender. Bitdefender found clear signs of AI assisted development, where AI generated lure docs and code placeholders like “0123456789abcdef” and “change_this_key” were noticeable indicators, but stressed that this is human engineered APT tooling with AI used to speed design, not fully AI generated malware. The campaign exemplifies low footprint, cloud backed implants that are best detected via behavioral baselines (unusual DLL sideloading pairs and process–cloud service relationships) rather than simple signatures.
