A cybercrime forum post claiming to be selling Vercel data for $2 million, including access keys and source code, has resulted in a major breach at web infrastructure provider Vercel. The hacker accessed behind-the-scenes settings, potentially exposing API keys that allow software to connect to other services. Vercel traced the intrusion to a third-party AI tool used by an employee. The company has engaged in incident response firms and law enforcement to investigate any data exfiltrated.
