Chinese language Hackers Exploiting VMware 0-Day Flaw Since 2021

Mandiant and VMware not too long ago uncovered a classy cyber espionage marketing campaign. The attackers, a Chinese language group recognized as UNC3886, leveraged a recognized vulnerability in VMware software program (CVE-2023-34048) to take care of entry to the focused methods for over a yr.

This case highlights the significance of staying vigilant in opposition to persistent and evolving cyber threats.

Mandiant’s investigation revealed that UNC3886 employed superior strategies to focus on weak areas of expertise which are past the attain of antivirus software program.

This discovery underscores the necessity for a multi-layered safety method that goes past conventional antivirus measures.
