VOLTA is a mature stealer implant with an optional AI-integration layer. After stealing credentials, sessions, and cryptocurrency wallets, VOLTA sends a structured evidence bundle to an LLM to rank the victim’s assets by monetization value. If a model refuses to perform the target assessment, VOLTA fails over to a three-model chain, implying a direct engineering effort and expectation of hitting model guardrails. This stealer is self-deleting, and there is no attacker-owned infrastructure. The…

Cisco Talos observed a new AI-integrated command-and-control (C2) framework in the wild called “NIK C2.” NIK C2 contains a Windows implant, using which, an actor can dump credentials, stream the victim's keystrokes to collect the targeted victim’s sensitive data, and instruct an integrated AI model to analyze the harvested data, all within the compromised session. In this framework, the actor has abused the OpenAI Chat Completions application programming interface (API), which is a HTTP…

Building your malware analysis lab is a key point before playing with malware. Today, thanks to virtualization, it's convenient to play with snapshots in your lab. Start a new investigation from a clean snapshot and take some more when you reached a critical step. But, if you need to revert to a previous snapshot, all changes applied to the VM are... lost! Therefore, it's important to store important data outside the VM. If you do malware analysis with Ghidra[1], your work lives in "projects".…
