Windows and Linux systems are being targeted by a ransomware variant called HelloXD, with the infections also involving the deployment of a backdoor to facilitate persistent remote access to infected hosts.
A new covert Linux kernel rootkit named Syslogk has been spotted under development in the wild and cloaking a malicious payload that can be remotely commandeered by an adversary using a magic network traffic packet.
A new peer-to-peer botnet named Panchan appeared in the wild around March 2022, targeting Linux servers in the education sector to mine cryptocurrency.
A new Linux rootkit malware named ‘Syslogk’ is being used in attacks to hide malicious processes, using specially crafted "magic packets" to awaken a backdoor laying dormant on the device.
Researchers have unearthed a discovery that doesn’t occur all that often in the realm of malware: a mature, never-before-seen Linux backdoor that uses novel evasion techniques to conceal its presence on infected servers, in some cases even with a forensic investigation.
Security researchers have discovered some new Linux-based ransomware that's being used to attack VMware ESXi servers, a bare-metal hypervisor for creating and running several virtual machines (VMs) that share the same hard drive storage. Called Cheerscrypt, the bad app is following in the footsteps of other ransomware programs—such as LockBit, Hive and RansomEXX—that have found ESXi an efficient way to infect many computers at once with malicious payloads.
A group of cybersecurity researchers from BlackBerry and Intezer discovered a new Linux malware that, according to the companies, would be “nearly impossible to detect.”
