Two years after the Log4Shell vulnerability in the open source Java-based Log4j logging utility was disclosed, circa one in four applications are dependent on outdated libraries, leaving them open to exploitation.
Research from security shop Veracode revealed that the vast majority of vulnerable apps may never have updated the Log4j library after it was implemented by developers as 32 percent were running pre-2015 EOL versions.
From mid-June through mid-July 2022, CISA conducted an incident response engagement at a Federal Civilian Executive Branch (FCEB) organization where CISA observed suspected advanced persistent threat (APT) activity. In the course of incident response activities, CISA determined that cyber threat actors exploited the Log4Shell vulnerability in an unpatched VMware Horizon server, installed XMRig crypto mining software, moved laterally to the domain controller (DC), compromised credentials, and then implanted Ngrok reverse proxies on several hosts to maintain persistence.
A Chinese advanced persistent threat tracked as Deep Panda has been observed exploiting the Log4Shell vulnerability in VMware Horizon servers to deploy a backdoor and a novel rootkit on infected machines with the goal of stealing sensitive data.
The prolific China APT41 hacking group, known for carrying out espionage in parallel with financially motivated operations, has compromised multiple U.S. state government networks, according to cybersecurity giant Mandiant. The group — seemingly undeterred by U.S. indictments against five APT41 members in 2020 — conducted a months-long campaign during which it targeted and successfully breached […]
Hackers aligned with the government of Iran are exploiting the critical Log4j vulnerability to infect unpatched VMware users with ransomware, researchers said on Thursday.
