The implant features surveillance, theft, lateral movement, and evasion capabilities, including credential dumping, RDP session hijacking, process hollowing, and a C2-driven screen lock ransomware module. \u00abNIK C2 contains a Windows implant, using which, an actor can dump credentials, stream the victim\u2019s keystrokes to collect the targeted victim\u2019s sensitive data, and instruct an integrated AI model to analyze the harvested data, all within the compromised session,\u00bb Talos <a href=\"https:\/\/blog.talosintelligence.com\/nik-c2-new-ai-enabled-framework\/\" target=\"_blank\">said<\/a>. \u00abIn this framework, the actor has abused the OpenAI Chat Completions application programming interface (API), which is an HTTP endpoint that enables ChatGPT-style conversations programmatically. In addition to the features that enable theft, an actor can also deploy desktop screen-locking ransomware via the NIK C2 implant onto the victim machine, leading to a ransom demand in Bitcoin or USDT cryptocurrencies.\u00bb Three different versions of the malware have been identified to date since August 12, 2026.
