What to do
AI-suggested
Organizations should immediately restrict local access to systems running vulnerable versions of Veritas Backup Exec, ensuring only trusted administrators have login privileges. Implement application whitelisting and endpoint detection to monitor and block unauthorized DLL loads or suspicious process behaviors. Employ strict file system permissions on directories involved in DLL loading to prevent unauthorized file placement. Regularly audit and monitor event logs for anomalies related to DLL loading or Backup Exec processes. Until the official hotfix (22.2 HotFix 917391 or later) is applied, consider isolating Backup Exec servers from untrusted users and networks to reduce attack surface. Coordinate with Veritas support to obtain and deploy patches promptly once available. Additionally, educate administrators about the risks of DLL hijacking and enforce the principle of least privilege to minimize potential exploitation vectors. Maintain up-to-date backups and verify their integrity to mitigate impact in case of compromise.
