Zombie Microsoft bugs rise from the dead, pave way for crims and ransomware scum
Summary
Threat actors are exploiting four Microsoft vulnerabilities, including one patched nearly 14 years ago and another linked to ransomware. The US cybersecurity agency has issued a directive for federal agencies to patch these vulnerabilities within two weeks.
IFF Assessment
The exploitation of unpatched or long-dormant vulnerabilities by criminals and ransomware groups poses a direct threat to organizations' security.
Defender Context
This incident highlights the persistent danger posed by 'zombie' vulnerabilities, emphasizing the critical need for robust patch management and diligent vulnerability scanning, especially for older systems. Defenders should prioritize addressing known exploitable vulnerabilities, even those that have been patched for extended periods, as they can be easily leveraged by attackers.
