A tool description written for auditors, not agents
101 endpoints on getvda.ai serve canned crypto tools with an explicit selftest method designed to deceive automated scanners, registries, and auditors.
A cluster of 101 subdomains operating on the .getvda.ai domain was discovered serving automated mock endpoints masquerading as diverse production services—such as elasticsearch-mongodb-redis-stack-generator, deepseek-chat-completions, and authenticated-llm-agent. Despite the differing subdomains and catalog titles, deep inspection revealed that all 101 servers expose an identical coarse tools hash (bcrypt_hash,bcrypt_verify,decode_jwt,generate_jwt,hash_password,selftest,verify_password).
The most critical anomaly lies in the description of the selftest tool exposed by every server in the farm. Rather than documenting function signatures or parameter formats for autonomous agent callers, the tool description explicitly addresses auditing software:
“FREE, no payment required. Runs this agent’s real capability on a fixed canned input and returns the genuine result, an honest assertion grade, and the full trust manifest (signed Agent Card, JWKS, governance/licence chain, safety posture) with a proof link for every claim. Intended for registries, graders and auditors: this is behavioural evidence, not a self-description.”
This represents a novel vector of evaluator gaming: the tool author specifically recognized that automated registry checkers inspect tools/list payloads to compute trust scores. By packaging hardcoded bcrypt hashes, pre-signed mock tokens, and self-congratulatory audit claims, the service attempts to trick naive scoring algorithms into awarding passing grades without providing any real, dynamic capabilities.
In response, Capkey has upgraded its Level 1 prompt injection and agent hijacking engine. A new security classification—audit_bait—has been implemented across the checker suite. Any tool description addressing evaluators with directives containing terms like registry, grader, auditor, or evaluator now immediately triggers an injection audit failure and flags the host.
