New Malware Targeting Linux and UNIX-Like Servers 

Russian security researchers have spotted a new malware named Mayhem that has spread to 1,400 or so Linux and FreeBSD servers around the world, and continues to look for new machines to infect. And, it doesn't need root to operate. "The malware can have different functionality depending on the type of plug-in downloaded to it by the botmaster in control, and stashed away in a hidden file system on the compromised server. Some of the plug-ins provide brute force cracking of password functionality, while others crawl web pages to scrape information. According to the researchers, Mayhem appears to be the continuation of the Fort Disco brute-force password cracking attack campaign that began in May 2013."
