Socket’s Threat Research Team has identified a tightly coordinated campaign abusing malicious Chrome extensions to infiltrate enterprise HR and ERP environments such as Workday, NetSuite, and SAP SuccessFactors. Five extensions—installed more than 2,300 times—operate as a single ecosystem, quietly harvesting session data, disabling built-in safeguards, and setting the stage for full account compromise. Although they appear to be independent utilities, shared infrastructure and near-identical code reveal a unified operator running a modular toolkit. On the surface, these extensions present themselves as productivity or access-management aids, promising smoother logins to premium enterprise tools. Slick storefronts, dashboards, and reassuring language frame them as helpers or even security enhancers. In reality, they abuse common browser permissions and publish misleading privacy policies that deny any form of data collection. Once installed, they quietly siphon authentication cookies, transmit them to attacker-controlled APIs, and maintain persistence by monitoring sessions continuously. Beyond credential theft, the campaign actively suppresses incident response. Certain extensions manipulate page content to block access to administrative and security settings, preventing users from changing passwords, reviewing audit logs, or adjusting authentication policies. These blocks persist through reloads and dynamic page updates, effectively blinding defenders while the compromise remains active. One component escalates the threat further by injecting stolen cookies directly into an attacker’s browser, enabling instant session hijacking without passwords or MFA. With no legitimate product presence behind the associated domains, Socket has requested takedowns from the Google Chrome Web Store and urges organizations to audit extensions, block related infrastructure, and reset credentials from clean systems.
