Full timeline through 2026
2026 — internal systems breach; forum sale claims (~$2M); Mandiant response
Unverified claim — treat actor counts cautiously. In mid-to-late April 2026, Vercel publicly confirmed unauthorized access to certain internal systems, stating it engaged external incident response (reporting frequently cited Google/Mandiant–family firms), notified law enforcement, and was contacting affected parties. Follow-on analyses (e.g., Security Boulevard, InfoWorld) tied the intrusion path to abuse of a third-party AI/OAuth integration context—often named in press as Context.ai / Google Workspace OAuth—rather than a core Vercel platform flaw. Trade and int Exposed categories include Internal keys, env/config context, limited customer subset per company—exact categories under investigation. No attested victim count is published for this row yet. See the vercel 2026 record and canonical BreachHistory entry.
