Cybersecurity firm Trellix has been hit by a ransomware attack, with the RansomHouse group claiming responsibility and publishing screenshots showing access to internal services and management dashboards. Trellix confirmed that part of its source code repository was breached but says there's no evidence the code was exploited or that its distribution process was affected. The timing of the attack suggests a possible connection to a broader supply chain campaign that has also impacted other security firms like Checkmarx and Bitwarden, though that link hasn't been confirmed.
