To mitigate the issue, follow these steps:
- Apply security updates promptly, especially for the specified vulnerabilities, on all applications and operating systems. Consult the Microsoft Security Update Guide for comprehensive information on available Microsoft Security updates.
- Follow the principle of least privilege and maintain credential hygiene. Avoid using domain-wide, admin-level service accounts. Restrict local administrative privileges to mitigate the potential installation of remote access trojans (RATs) and other undesirable applications.
- Network segmentation is useful in constraining the propagation of malware infections. The process involves partitioning a network into smaller segments, effectively confining an infection to a single segment rather than permitting its unrestricted spread across the entire network.
- Promote the use of Microsoft Edge and other web browsers that support SmartScreen, a feature identifying and blocking malicious websites, including phishing sites, scam sites, and those hosting exploits or malware.
- Block the launch of downloaded executable content by disabling JavaScript or VBScript.
