Analysis of attacks against Linux SSH servers during Q1 2026 reveals P2PInfect worm as the dominant threat, representing 70.3% of all attack sources. DDoS botnets including Mirai, XMRig, Prometei, and CoinMiner were identified as primary threats. A notable campaign involved installing V2Ray proxy tools on compromised systems, attributed to a suspected Chinese threat actor. Attackers employed SSH brute-force techniques to gain access, executed reconnaissance commands to assess system information, and deployed V2Ray for proxy node operations. The campaign targeted poorly secured SSH servers with weak credentials, emphasizing the need for strong password policies, access controls, and network monitoring to detect unusual outbound connections and proxy-related activities.

A North Korean malware was discovered in an Upwork cryptocurrency project, leading to a five-day investigation into active Lazarus Group infrastructure. The malware utilized three infection mechanisms: VSCode auto-execution, backend RCE via Function Constructor, and cookie payload delivery. The infrastructure included Vercel-hosted Stage 1 C2 servers and dedicated Stage 2 C2 servers. A timing oracle allowed for token enumeration, revealing three active campaigns. The payload chain consisted of various modules for data extraction, RAT functionality, and cryptocurrency mining. The investigation uncovered sophisticated persistence mechanisms, masquerading techniques, and a custom binary protocol. Real-time defensive responses from the operators were observed during reconnaissance. The infrastructure blended legitimate-looking development projects with malicious activities for cover.
