A widespread information theft marketing campaign has allowed hackers to breach gross sales automation platform Salesloft to steal OAuth and refresh tokens related to the Drift synthetic intelligence (AI) chat agent.
The exercise, assessed to be opportunistic in nature, has been attributed to a risk actor tracked by Google Menace Intelligence Group and Mandiant, tracked as UNC6395.

Salesloft, in an advisory issued August 20, 2025, mentioned it recognized a security concern within the Drift software and that it has proactively revoked connections between Drift and Salesforce. The incident doesn’t have an effect on prospects who don’t combine with Salesforce.

“What’s most noteworthy in regards to the UNC6395 assaults is each the size and the self-discipline,” Cory Michal, CSO of AppOmni, mentioned. “This wasn’t a one-off compromise; a whole bunch of Salesforce tenants of particular organizations of curiosity had been focused utilizing stolen OAuth tokens, and the attacker methodically queried and exported information throughout many environments.”
“They demonstrated a excessive degree of operational self-discipline, working structured queries, looking out particularly for credentials, and even making an attempt to cowl their tracks by deleting jobs. The mix of scale, focus, and tradecraft makes this marketing campaign stand out.”

“By first infiltrating distributors and repair suppliers, the attackers put themselves in place to pivot into downstream prospects and companions,” Michal added. “That makes this not simply an remoted SaaS compromise, however probably the muse for a a lot bigger marketing campaign aimed toward exploiting the belief relationships that exist throughout the know-how provide chain.”
