The group, Microsoft has reported, has tried to hack a US presidential campaign and to install ransomware in an attempt to generate revenue or disrupt adversaries. Microsoft has dubbed one group Phosphorous. Thursday’s report said that TunnelVision overlaps with several threat groups exposed by other researchers over the years. People trying to determine if their organization is affected should look for unexplained outgoing connections to legitimate public services. Multiple legitimate services are used by the hackers. Download and run tunneling tools, including Plink and Ngrok, which are used to tunnel remote desktop protocol traffic.Harvest credentials using ProcDump, SAM hive dumps, and comsvcs MiniDump.Create a backdoor user and adding it to the network administrators group.TunnelVision members use it after it's installed. The publicly available one appears to be a variant of the PowerShell used here. Once installed, a shell allows the hackers to execute their own commands. VMware and other enterprise software use Apache Tomcat to deploy and serve Java-based Web apps. TunnelVision attackers have been actively exploiting the vulnerability to run malicious PowerShell commands, deploy backdoors, create backdoor users, harvest credentials, and perform lateral movement, according to company researchers. The research shows that the target is organizations that are running a product that runs on Windows, macOS, and Linux.

The bug bit the Internet’s biggest players and was widely targeted in the wild after it became known. CVE-2021-44228 (or Log4Shell, as the vulnerability is tracked or nicknamed) allows attackers to easily gain remote control over computers running apps in the Java programming language.

Recently, SentinelOne reported, TunnelVision has started exploiting a critical vulnerability in Log4j, an open source logging utility that’s integrated into thousands of apps. Two of the group's better-known targets are Microsoft Exchange and FortiOS. In the past, TunnelVision has used 1-day vulnerabilities to hack organizations that have yet to install the fix. The name is meant to emphasize the heavy reliance on tunneling tools and the unique way it deploys them. Researchers said on Thursday that the Log4j vulnerability is being exploited by hackers aligned with the government of Iran.
