Hecker

Also known ashecker

Hecker is a threat actor attributed by Pillar Security to an active LLMjacking operation dubbed “Bizarre Bazaar” / “Operation Bizarre Bazaar,” targeting exposed or weakly authenticated self-hosted LLM service endpoints. Hecker is also known as Sakuya and LiveGamer101. The campaign scans the internet for unauthenticated Ollama endpoints (commonly port 11434), vLLM servers, and OpenAI-compatible APIs (commonly port 8000), rapidly identifying new exposed endpoints (often within hours of appearing in Shodan/Censys). Activity includes validating endpoint access/response quality, monetizing stolen AI compute (including cryptocurrency mining), reselling unauthorized LLM API access via a resale service advertised as silver[.]inc (a “Unified LLM API Gateway”) and promoted on Telegram/Discord, and attempting to exfiltrate prompt/conversation data. Pillar also reported attempts to pivot internally via Model Context Protocol (MCP) servers. Pillar assessed a three-actor criminal supply chain (scanner, validator, reseller) supporting the operation, with resale infrastructure tied to silver[.]inc and a promoted project called “NeXeonAI.” The campaign was reported as ongoing at time of publication, with SilverInc remaining operational.
