The UK’s National Health Service (NHS) Digital has issued an advisory warning of attackers actively targeting Log4j vulnerability CVE-2021-44228 in VMware Horizon servers to establish persistence.<\/p>\n

Officials say the threat group is unknown. The observed attacks target the Log4j vulnerability in the Apache Tomcat service, which is embedded within VMware Horizon. <\/p>\n

Their attack activity likely contains a reconnaissance phase, in which they use the Java Naming and Directory Interface (JNDI) via Log4Shell payloads to call back to malicious infrastructure, the NHS wrote in its advisory.<\/p>\n

“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,” officials explained. <\/p>\n

The attacker could then use this Web shell to conduct malicious actions such as deploying more malware, exfiltrating data, or launching a ransomware attack. In the advisory, the NHS noted more VMware systems may be vulnerable and companies should review the VMSA-2021-0028<\/a> security advisory: VMware Response to Apache Log4j Remote Code Execution Vulnerability<\/p>\n
