Drift Platform Exploitation and OAuth Token Theft
Following their reconnaissance part, the attackers pivoted to take advantage of Drift’s Amazon Net Companies (AWS) surroundings, the place they efficiently obtained OAuth tokens for Drift prospects’ know-how integrations.
This represents the crucial provide chain vulnerability that enabled the widespread assault throughout tons of of organizations.
OAuth tokens function digital keys that authorize purposes to entry person information throughout completely different platforms with out requiring password authentication.
Within the case of Drift, these tokens enabled the chatbot platform to combine with buyer techniques like Salesforce, Google Workspace, and different enterprise purposes.
By stealing these tokens, UNC6395 successfully inherited the identical trusted entry privileges, permitting it to bypass conventional safety controls.
The technical sophistication of this part is clear within the attackers’ potential to entry AWS-hosted OAuth credentials and extract them with out detection.
This means a deep understanding of cloud infrastructure and token administration techniques, attribute of superior persistent risk (APT) teams.
Between August 8 and 18, 2025, UNC6395 launched a scientific information exfiltration marketing campaign concentrating on Salesforce situations related by Drift integrations. The attackers employed subtle strategies to maximise information theft whereas trying to evade detection.
The first goal of the marketing campaign was credential harvesting somewhat than fast information monetization. UNC6395 systematically searched by exfiltrated information for beneficial secrets and techniques, together with:
Amazon Net Companies (AWS) entry keys (AKIA format)
Snowflake-related entry tokens
VPN credentials and configuration info
Generic passwords and authentication strings
API keys and repair account credentials
This deal with credential harvesting signifies a strategic strategy aimed toward enabling secondary assaults and lateral motion throughout sufferer environments.
The stolen credentials may present attackers with persistent entry to cloud infrastructure and business-critical techniques far past the preliminary Salesforce breach.
