The critical VMware vulnerability with code CVE-2022-22954 was discovered to be used by threat actors for remote code execution in botnet and Log4Shell-driven attacks. Although VMware has announced that the vulnerability has been fixed, cyber-attacks continue to infect devices via botnets and create a backdoor with Log4Shell.
Two VMware Vulnerabilities Exploited
One of the vulnerabilities that threat actors use in attacks is CVE-2022-22954 affecting VMware Workspace One Access and Identity Manager with a CVSS score of 9.8. Workspace ONE is used to deliver enterprise applications to devices. Identity Manager is an authentication tool for the platform. The vulnerability that affects these two critical tools allows attackers with network access to RCE.
Another flaw exploited by threat actors is the CVE-2022-22960 privilege escalation vulnerability with a CVSS score of 7.8. This affects Workspace ONE Access, Identity Manager, and vRealize Automation.
Cybersecurity experts state that by combining the two vulnerabilities, threat actors can achieve an ideal exploitation vector.

Mostly Using PoC Published on GitHub
In the short analysis published by Barracuda, it is stated that exploitation attempts were observed immediately after the proof-of-concept was published on GitHub. Although most of these initiatives are seen as “research,” it can be said that they are preliminary for future cyber attacks.
In actual exploit attempts, IPs and EnemyBot instances have been detected that host Mirai DDoS botnet malware. Log4Shell exploit attempts are also notable.
Sysrv-k Botnet Infects Windows and Linux Systems
Microsoft has announced that it has discovered a botnet that distributes cryptocurrency miners on Windows and Linux systems. According to the flood on the Microsoft Security Intelligence Twitter account, the new botnet is a new variant of the notorious Sysrv.
According to the tweet thread, the botnet performs a web scan to identify vulnerable servers, looking for security vulnerabilities such as remote code execution and random file downloads. The botnet is thought to use the RCE vulnerability, which mostly affects Spring Cloud Gateway and Oracle Communications Cloud-Native products with the code CVE-2022-22947.
