Data leak
Crunchbase Data Breach - ShinyHunters Vishing (2M Records)
Primary Source βIncident Details
In January 2026, ShinyHunters breached Crunchbase (a major business intelligence and startup data platform) via vishing β attackers impersonated internal employees to social-engineer IT support into resetting Okta SSO credentials. After Crunchbase declined to pay ransom, the group publicly leaked a 402 MB compressed archive on January 26, 2026, containing approximately 2 million records including personally identifiable information (names, email addresses, phone numbers) alongside corporate data such as signed contracts and internal documents. Security researcher Alon Gal verified portions of the leaked data. Crunchbase stated that operations were not affected and that the breach was contained. The incident is part of ShinyHunters’ broader 2025β2026 campaign targeting companies via Salesforce/Okta vishing, alongside breaches of Qantas, Vietnam Airlines, CarGurus, Betterment, SoundCloud, and dozens of others.
