Salesforce and Gainsight are investigating unauthorized data access incidents involving OAuth token abuse, with connections to the ShinyHunters hacking group.
🚨 BREAKING: Salesforce & Gainsight Hit by OAuth Exploit
Salesforce just dropped the bomb: they're investigating unauthorized data access through compromised OAuth tokens linked to Gainsight integrations. This ain't your average breach—we're talking sophisticated token abuse with ties to the infamous ShinyHunters crew.
The investigation reveals threat actors manipulated OAuth authorization flows to gain persistent access to customer data. Multiple third-party apps have been pulled from marketplaces as both companies scramble to contain the fallout.
Gainsight confirmed they're working with Salesforce on the forensic analysis, warning customers about potential data exposure through compromised integrations. The incident highlights the growing risk of supply-chain attacks in the SaaS ecosystem.
- • OAuth token manipulation enabling persistent data access
- • Connection to ShinyHunters hacking group confirmed
- • Multiple third-party apps removed from marketplaces
- • Joint investigation between Salesforce and Gainsight

This is exactly why OAuth security should be your top priority in 2025. Threat actors are getting smarter about abusing trusted authentication flows, and even enterprise giants like Salesforce aren't immune.
