The cybersecurity company said it's associating the attacks to a separate Iranian cluster not because they are unrelated, but owing to the fact that 'there is at present insufficient data to treat them as identical to any of the aforementioned attributions. The Cybersecurity and Infrastructure Security Agency (CISA) in September warned organizations to patch VMware Horizons Log4Shell flaws, some nine months after VMware released its Log4Shell patches for Horizon servers. SentinelOne also said it identified similarities in the mechanism used to execute the reverse web shell with another PowerShell-based implant called PowerLess that was disclosed by Cybereason researchers earlier this month.Īll through the activity, the threat actor is said to have utilized a GitHub repository known as 'VmWareHorizon' under the username 'protections20' to host the malicious payloads.

The PowerShell commands are used as a launchpad to download tools like Ngrok and run further commands by means of reverse shells that are employed to drop a PowerShell backdoor that's capable of gathering credentials and executing reconnaissance commands. TunnelVision, an Iranian-affiliated hacker group, was detected attacking Log4j on VMware Horizon servers to compromise corporate networks in the Middle East and the United States. A Chinese advanced persistent threat tracked as Deep Panda has been observed exploiting the Log4Shell vulnerability in VMware Horizon servers to deploy a backdoor and a novel rootkit on infected machines with the goal of stealing sensitive data. Combined with other reports, this suggests VMware.

'TunnelVision attackers have been actively exploiting the vulnerability to run malicious PowerShell commands, deploy backdoors, create backdoor users, harvest credentials and perform lateral movement,' the researchers said. Starting in late December, Red Canary researchers observed a notable increase in threat actor exploits of vulnerable VMware Horizon servers. 'TunnelVision activities are characterized by wide-exploitation of 1-day vulnerabilities in target regions,' SentinelOne researchers Amitai Ben Shushan Ehrlich and Yair Rigevsky said in a report, with the intrusions detected in the Middle East and the U.S.Īlso observed alongside Log4Shell is the exploitation of Fortinet FortiOS path traversal flaw ( CVE-2018-13379) and the Microsoft Exchange ProxyShell vulnerability to gain initial access into the target networks for post-exploitation. 1107 Vulnerability scanning tools automated scanning tools, 593 databases, 593 defenses, 593 hackers, 591 Nessus, 593 SATAN, 593 scripting language. (Jaiz Anuar / Getty Images) VMware released patches related to Log4Shell, a vulnerability in a popular Java framework that left countless servers at risk, in December 2021.

A 'potentially destructive actor' aligned with the government of Iran is actively exploiting the well-known Log4j vulnerability to infect unpatched VMware Horizon servers with ransomware.Ĭybersecurity firm SentinelOne dubbed the group ' TunnelVision' owing to their heavy reliance on tunneling tools, with overlaps in tactics observed to that of a broader group tracked under the moniker Phosphorus as well as Charming Kitten and Nemesis Kitten.
