The North Korean state-sponsored Lazarus hacking group is breaching Windows Internet Information Service web servers to hijack them for malware distribution. South Korean security analysts at ASEC previously reported that Lazarus was targeting IIS servers for initial access to corporate networks.

The U.S. Cybersecurity and Infrastructure Security Agency has given federal agencies three weeks to secure Adobe ColdFusion servers on their networks against two critical security flaws exploited in attacks, one of them as a zero-day. According to the binding operational directive issued by CISA in November 2021, Federal Civilian Executive Branch Agencies are required to patch their systems against all bugs added to the Known Exploited Vulnerabilities catalog.

Thousands of Citrix Netscaler ADC and Gateway servers exposed online are likely vulnerable against a critical remote code execution bug exploited by unauthenticated attackers in the wild as a zero-day. "We tag all IPs where we see a version hash in a Citrix instance. This is due fact that Citrix has removed version hash information in recent revisions," Shadowserver said.

Mallox ransomware activities in 2023 have witnessed a 174% increase when compared to the previous year, new findings from Palo Alto Networks Unit 42 reveal. "Mallox ransomware, like many other ransomware threat actors, follows the double extortion trend: stealing data before encrypting an organization's files, and then threatening to publish the stolen data on a leak site as leverage to convince victims to pay the ransom fee," security researchers Lior Rochberger and Shimi Cohen said in a new report shared with The Hacker News.

Two more security flaws have been disclosed in AMI MegaRAC Baseboard Management Controller software that, if successfully exploited, could allow threat actors to remotely commandeer vulnerable servers and deploy malware. "These new vulnerabilities range in severity from High to Critical, including unauthenticated remote code execution and unauthorized device access with superuser permissions," Eclypsium researchers Vlad Babkin and Scott Scheferman said in a report shared with The Hacker News.
