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…
