Threat actors are exploiting a critical remote code execution bug in Atlassian to turn cloud environments into cryptomining networks. Trend Micro uncovered attacks that drain network resources using the flaw CVE-2023-22527 in Confluence Data Center and Server. The attackers use various methods and recommended patching the environment to prevent exploitation.
Key takeaways from the meeting notes:
1. Threat actors are exploiting a critical remote code execution (RCE) Atlassian bug (CVE-2023-22527) discovered in January. This bug received a 10 out of 10 on the Common Vulnerability Scoring System (CVSS) and has been exploited for cryptojacking attacks that drain network resources.
2. Trend Micro discovered two separate attacks that use the CVE-2023-22527 flaw in Confluence Data Center and Confluence Server for cryptojacking activities, using methods such as shell scripts, XMRig miners, targeting of SSH endpoints, and maintaining persistence via cron jobs.
3. Administrators of cloud environments are advised to patch the bug, practice network segmentation, conduct regular security audits and vulnerability assessments, and have a solid incident response plan in place to prevent vulnerabilities from being exploited.
