“Organizations should thoroughly research their exposure to potential Log4j vulnerabilities, as they may impact commercial, open-source and custom software that in some cases may not have regular security support,” says the Sophos report. Apache had to issue four patches to address this and subsequently discovered holes. Instead, the cryptominer installer script is directly executed from the Apache Tomcat component of the Horizon server.ĭiscovered in December, 2021, the vulnerability ( CVE-2021-44228) enables a remote attacker to take control of a device on the internet through text messages if it runs certain versions of Log4j2. Unlike others, this wave doesn’t rely on an installed Cobalt Strike beacon back to the hackers. “The largest wave of Log4j attacks aimed at Horizon that we have detected began January 19, and is still ongoing,” the report says. And while the attempts have dropped off since then, they are continuing.

In a report issued this week, the company says attempts to leverage Horizon and install cryptocurrency mining software or backdoors grew in January. Threat actors continue trying to compromise VMWare Horizon systems through unpatched vulnerabilities in applications’ Log4j2 Java libraries, say researchers at Sophos.
