SI agents cut the search for weak points in someone else's defenses to hours, and even leading labs are exposed through third-party services.
According to the Washington Post (relayed by TASS and Tech Startups), Cathedral, a company founded by former DOGE staff, used SI agents to gain access to part of Anthropic's internal systems in under 12 hours, through vulnerabilities in third-party sales and administration software. The access covered meeting transcripts, salary and job-offer information, Slack messages, and data from the sales, HR and IT departments. The research was carried out under a bug bounty program. Anthropic confirmed access to a "limited set" of systems and reported the case to federal agencies; it says the researchers did not reach customer conversations with Claude, model responses, proprietary code or weights, and that Cathedral overstated the national security implications. According to the Washington Post, a White House official called the speed of the intrusion alarming.
