This morning, SophosLabs is publishing a report on a malware family whose infection numbers have been steadily growing since the beginning of the year. This malware, with its hard-to-pronounce name, has been getting regular updates and feature enhancements that seem to be focused on its ability to conceal itself from detection on infected computers. In our report, we’ve taken a deep dive into what makes the Glupteba malware distinctive. The core malware is, in essence, a dropper with extensive backdoor functionality, but it is a dropper that goes to great efforts to keep itself, and its various components, hidden from view by the human operator of an infected computer, or the security software charged with its protection.
