A new malware program that functions as a module for the Apache and Nginx Web servers is being sold on cybercrime forums, according to researchers from security firm IntelCrawler.
The malware is called Effusion and according to the sales pitch seen by IntelCrawler, a start-up firm based in Los Angeles that specializes in cybercrime intelligence, it can inject code in real time into websites hosted on the compromised Web servers. By injecting content into a website, attackers can redirect visitors to exploits or launch social engineering attacks.
The Effusion module works with Nginx from version 0.7 up to the latest stable version, 1.4.4, and with Apache running on 32- and 64-bit versions of Linux and FreeBSD. ModulModules extend Apache’s and Nginx’s core functionality.
