Along with the popularity of the Linux OS, the number of attack campaigns has also shot up. OrBit marks the fourth Linux malware to have been detected by security researchers within three months. Another malicious operation, dubbed CuteBoi, has been discovered posing a software supply chain threat through NPM packages. Assumed to be at a nascent stage, the packages include code from eazyminer, a tool for mining Monero via unused resources on web servers.
Besides, Fortinet released a large number of firmware and software updates fixing a wide range of vulnerabilities. A hacker could abuse these flaws to access MySQL databases while achieving privilege escalation across Windows versions.

Top Malware Reported in the Last 24 Hours
New Linux-based backdoor
A never-seen-before Linux backdoor has surfaced that can be installed either with persistence capabilities or as a volatile implant. Known as OrBit, the malware infects all of the running processes on the compromised machines. The backdoor aims to extract data by hooking the read and write functions to capture data during the machine runtime.
When Follina brought a company
Fortinet researchers stumbled across a malicious document that not only exploited the Follina vulnerability (CVE-2022-30190) but also pulled in the Rozena backdoor. The backdoor injects a remote shell and establishes a connection with the attacker’s machine. Hackers carry out a fileless attack by leveraging the public Discord CDN attachment service.
New unusual RaaS family
U.S. cybersecurity and intelligence agencies found the new Maui ransomware, which is the brainchild of North Korean government-backed hackers. The ransomware has been targeting the healthcare sector in the U.S. since at least May 2021. What’s odd about this malware family is that it lacks multiple key features that one can generally associate with a RaaS service.
