Threat researchers discovered GlassWASM, a WebAssembly-based malware distributed via trojanized extensions on the Open VSX marketplace. The malware uses ChaCha20 encryption to evade static analysis and leverages the Solana blockchain as a resilient C2 dead-drop to retrieve and execute OS-specific second-stage payloads via Node.js.
PHANTOMPULSE is a sophisticated RAT attributed to DPRK-aligned actors that utilizes hardware breakpoints to bypass AMSI, WLDP, and ETW. It establishes a resilient, sinkhole-able command and control channel by resolving C2 URLs from blockchain transaction inputs and employs multiple process injection and UAC bypass techniques.
Threat actor REF6598 is targeting the financial and cryptocurrency sectors using social engineering to trick victims into opening a malicious Obsidian vault. The attack leverages Obsidian's community plugins to execute cross-platform attack chains, culminating in the deployment of the PHANTOMPULSE RAT on Windows and an AppleScript dropper on macOS.
