eCommerce servers are being targeted with remote access malware that hides on Nginx servers in a way that makes it virtually invisible to security solutions. “NginRAT essentially hijacks a host Nginx application to stay undetected. To do that, NginRAT modifies core functionality of the Linux host system. When the legitimate Nginx web server uses such functionality (eg dlopen), NginRAT intercepts it to inject itself.”
Security researchers have discovered a Linux-based remote access trojan (RAT) that uses an unusual stealth technique to remain out of sight from security products. The malware, dubbed CronRat, hides in the calendar subsystem of Linux servers (“cron”) on a non-existent day, 31 February, according to a blog post by security researchers at Sansec.
Attackers are deploying a Linux backdoor on compromised e-commerce servers after injecting a credit card skimmer into online shops' websites.
The stealthy LightBasin hacking group (also known as UNC1945) is infiltrating telecommunications companies around the world in a campaign that researchers have linked to intelligence gathering and cyber espionage. LightBasin's primary focus is on Linux and Solaris servers that are critical for running telecommunications infrastructure – and are likely to have less security measures in place than Windows systems.
Multiple malicious packages have been identified on the npm registry this month. These packages disguise themselves as legitimate JavaScript libraries, but have been caught launching cryptominers on Linux, Windows and MacOS machines.
The newly discovered FontOnLake malware family delivers backdoor and rootkit components to infect Linux systems concealed in legitimate binaries.
