VMware ESXi zero-days likely exploited a year before disclosure

BleepingComputer

Cybersecurity researchers have uncovered that a group of Chinese-speaking hackers exploited vulnerabilities in VMware ESXi, using a compromised SonicWall VPN appliance to deploy an exploit toolkit. This toolkit appears to have been created over a year before the vulnerabilities were publicly disclosed. This means that the attackers had access to these exploits long before companies were aware of their existence, potentially allowing them to infiltrate networks unnoticed. Organizations using VMware ESXi should be particularly vigilant, as the vulnerabilities could lead to significant security breaches. The incident underscores the need for companies to regularly update their systems and monitor for unusual activity, as these types of attacks can have serious implications for data security.
