vmware horizon hackers are under exploit

#VMWARE HORIZON HACKERS ARE UNDER EXPLOIT CODE#

The exploitation begins with the simple and widely used '$' payload and spawns the following PowerShell command from Tomcat. The actor is taking advantage of the presence of the Apache Tomcat service embedded within VMware Horizon, which is vulnerable to Log4Shell. 'The web shell can then be used by an attacker to carry out a number of malicious activities such as deploying additional malicious software, data exfiltration, or deployment of ransomware.' 'Once a weakness has been identified, the attack then uses the Lightweight Directory Access Protocol (LDAP) to retrieve and execute a malicious Java class file that injects a web shell into the VM Blast Secure Gateway service.'

'The attack likely consists of a reconnaissance phase, where the attacker uses the Java Naming and Directory InterfaceTM (JNDI) via Log4Shell payloads to call back to malicious infrastructure,' explains the alert.

TARGETING APACHE TOMCAT IN VMWARE HORIZONĪccording to the NHS notice, the actor is leveraging the exploit to achieve remote code execution on vulnerable VMware Horizon deployments on public infrastructure. Log4Shell is an exploit for CVE-2021-44228, a critical arbitrary remote code execution flaw in the Apache Log4j 2.14, which has been under active and high-volume exploitation since December 2021.Īpache addressed the above and four more vulnerabilities via subsequent security updates, and Log4j version 2.17.1 is now considered adequately secure.

UK's National Health Service (NHS) has published a cyber alert warning of an unknown threat group targeting VMware Horizon deployments with Log4Shell exploits.
