Multiple Campaigns Exploit VMware Vulnerability to Deploy Crypto Miners and Ransomware

A now-patched vulnerability in VMware Workspace 1 Obtain has been observed getting exploited to supply both of those cryptocurrency miners and ransomware on afflicted machines.

“The attacker intends to use a victim’s sources as a great deal as possible, not only to set up RAR1Ransom for extortion, but also to spread GuardMiner to acquire cryptocurrency,” Fortinet FortiGuard Labs researcher Cara Lin stated in a Thursday report.

The issue, tracked as CVE-2022-22954 (CVSS rating: 9.8), issues a distant code execution vulnerability that stems from a case of server-facet template injection.

Despite the fact that the shortcoming was addressed by the virtualization expert services provider in April 2022, it has considering that occur less than active exploitation in the wild.

Fortinet stated it noticed in August 2022 attacks that sought to weaponize the flaw to deploy the Mirai botnet on Linux devices as effectively as the RAR1Ransom and GuardMiner, a variant of the XMRig Monero miner.

The Mirai sample is retrieved from a remote server and is designed to launch denial-of-assistance (DoS) and brute-pressure attacks aimed at perfectly-recognized IoT units by generating use of a listing of default qualifications.

The distribution of RAR1Ransom and GuardMiner, on the other hand, is realized by indicates of a PowerShell or a shell script dependent on the running program. RAR1ransom is also notable for leveraging the legit WinRAR utility to initiate the encryption procedure.

The findings are yet a different reminder that malware strategies proceed to actively exploit a short while ago disclosed flaws to split into unpatched methods, creating it essential that customers prioritize implementing important security updates to mitigate these threats.
