The group, Microsoft reported, has tried Hacking a US Presidential Campaign and installing ransomware in an attempt to generate revenue or obstruct adversaries. Thursday’s report noted that tunnelvision overlaps with many of the risk groups uncovered by other researchers over the years. Those trying to determine whether their organization has been affected should look for unexplained outgoing connections to these legitimate public services. Hackers use a number of legitimate services to obtain and obscure their activities. Download and run tunneling tools, including Plink and Ngrok, which are used to tunnel Remote Desktop Protocol traffic. Harvest credentials using ProcDump, SAM Hive Dump and comsvcs MiniDump.Create a backdoor user and add them to the Network Administrators group.Once it is installed, Tunnelvision members use it to: There seems to be a variant of PowerShell used here This a publicly available one. Once installed, a shell allows hackers to remotely execute commands of their choice over exploited networks. Huh.” written in post, “Typically, the threat actor exploits the Log4j vulnerability to initially run PowerShell commands directly, and then forward commands through the ps reverse shell, which are executed through the Tomcat process.” AdvertisementĪpache Tomcat is an open source web server used by VMware and other enterprise software to deploy and serve Java-based web apps. “Tunnelvision attackers are actively exploiting the vulnerability to run malicious PowerShell commands, deploy backdoors, create backdoor users, harvest credentials, and perform lateral movements,” said company researchers Amitai Ben Shushan Ehrlich and Yair Rigaevsky. Research from SentinelOne shows that targeting continues, and this time the target is organizations running VMware Horizon, a desktop and app virtualization product that runs on Windows, macOS, and Linux. bug bit Internet’s biggest players and was widely targeted in the wild after being known. CVE-2021-44228 (or Log4Shell, as the vulnerability is tracked or nicknamed) allows attackers to easily gain remote control over a computer running an app in the Java programming language. Recently, SentinelOne reported, TunnelVision has begun to exploit a critical vulnerability in Log4j, an open source logging utility that is integrated into thousands of apps.
