Windows infected with backdoored Linux VMs in new phishing attacks
A new phishing campaign dubbed ‘CRON#TRAP’ infects Windows with a Linux virtual machine that contains a built-in backdoor to give stealthy access to corporate networks. Using virtual machines to conduct attacks is nothing new, with ransomware gangs and cryptominers using them to stealthily perform malicious activity. However, threat actors commonly install these manually after they breach a network. A […]
New FASTCash malware Linux variant helps steal money from ATMs
North Korean hackers are using a new Linux variant of the FASTCash malware to infect the payment switch systems of financial institutions and perform unauthorized cash withdrawals.

New scanner finds Linux, UNIX servers exposed to CUPS RCE attacks
An automated scanner has been released to help security professionals scan environments for devices vulnerable to the Common Unix Printing System (CUPS) RCE flaw tracked as CVE-2024-47176. The flaw, which enables attackers to perform arbitrary remote code execution if certain conditions are met, was disclosed late last month by the person who discovered it, Simone Margaritelli. Although […]
Linux malware “perfctl” behind years-long cryptomining campaign
A Linux malware named “perfctl” has been targeting Linux servers and workstations for at least three years, remaining largely undetected through high levels of evasion and the use of rootkits. According to Aqua Nautilus researchers who discovered perfctl, the malware likely targeted millions of Linux servers in recent years and possibly caused infections in several […]
CUPS flaws enable Linux remote code execution, but there’s a catch
Under certain conditions, attackers can chain a set of vulnerabilities in multiple components of the CUPS open-source printing system to execute arbitrary code remotely on vulnerable machines. Tracked as CVE-2024-47076 (libcupsfilters), CVE-2024-47175 (libppd), CVE-2024-47176 (cups-browsed) and CVE-2024-47177 (cups-filters) and discovered by Simone Margaritelli, these security flaws don’t affect systems in their default configuration. CUPS (short for […]
