Checkmarx said its forensic probe into the incident is ongoing and that it&#8217;s actively working to verify the nature and scope of the posted data.\\n\\nFurthermore, the company said it has locked down access to the affected GitHub repository as part of its incident response efforts.\\n\\n\\&#8221;If we determine that customer information was involved in this incident, we will notify customers and all relevant parties immediately,\\&#8221; it said.\\n\\nThe development comes after the Dark Web Informer shared in an X post that the LAPSUS$ cybercrime group claimed three victims on its data leak site, one of which includes Checkmarx. The data, per the listing, contains source code, employee database, API keys, and MongoDB\/MySQL credentials.\\n\\nCheckmarx suffered a breach late last month following the Trivy supply chain attack, as a result of which two of its GitHub Actions workflows and two plugins distributed via the Open VSX marketplace were tampered with to push a credential stealer capable of harvesting a wide range of developer secrets. The threat actor known as TeamPCP claimed responsibility for the attack.\\n\\nLast week, the financially motivated group is suspected to have compromised Checkmarx&#8217;s KICS Docker image, along with the two VS Code extensions and a GitHub Actions workflow with a similar credential-stealing malware. This, in turn, had a cascading impact, leading to a brief compromise of the Bitwarden CLI npm package.\\n\\nFound this article interesting?
