Malware turned Linux and BSD servers into spamming machines - unnoticed for over 5 years!

Unnoticed for years, malware turned Linux and BSD servers into spamming machines

For over 5 years, and perhaps even longer, servers around the world running Linux and BSD operating systems have been targeted by an individual or group that compromised them via a backdoor Trojan, then made them send out spam, ESET researchers have found. The researcher began their investigation with a piece of malware they found on a server that was blacklisted for sending spam. They dubbed it Mumblehard. After analyzing it, they found that it has several distinct components: a generic backdoor that contacts its C&C server and downloads the spammer component and a general purpose-proxy. Mumblehard components are mainly Perl scripts encrypted and packed inside ELF binaries. In some cases, the Perl script contains another ELF executable with the same packer in the fashion of a Russian nesting doll," researcher Marc-Etienne Leveille shared in a paper detailing their findings. "We got interested in this threat because the way the Perl scripts used by the cybercriminals are packed inside ELF executables is uncommon and more complex than the average server threat."

Dell provide Windows on a Chromebook

Dell's Appliance for Wyse - vWorkspace product uses desktop virtualisation technology to deliver Windows desktop software to Chromebooks and other endpoints. Though brokered from a remote location, the Windows OS will be fully functional and run as if it were loaded locally.

As part of its Chrome for Work programme, Google has aggressively pushed Chromebooks into businesses as an alternative to Windows PCs. Chromebooks are thin, lightweight laptops for those who do most of their computing on the internet. Google has said that Chromebooks are tuned for the future of cloud computing, as they were built from the ground up to run rich web applications.
