Don’t believe these four myths about Linux security

Linux security mythsWe are well into the 21st century, but it is astonishing how people can still believe that Linux-based operating systems are completely secure. Indeed, “Linux” and “security” are two words that you rarely see together.

Just as some people believe Macs are immune to viruses, some Linux users have the same misconception – and who can blame them? After all, vendors have been telling them that for years.

In 2012, after an exponential rise of OS X malware (such as MacDefender and Flashback), Apple decided to change its homepage by removing sentences like “It doesn’t get PC viruses.”

SophosLabs research uncovers new developments in PlugX APT malware

SophosLabsThe notorious PlugX APT group is continuing to evolve and launch campaigns, most recently a five-month-long campaign targeting organizations in India.

PlugX now uses a new backdoor technique – hiding the payload in the Windows registry instead of writing it as a file on disk – according to a new technical paper from SophosLabs Principal Researcher Gabor Szappanos.

Although not unique to PlugX, this backdoor approach is still uncommon and limited to a few relatively sophisticated malware families.

SophosLabs: Elite APT hackers aren’t always elite coders

SophosLabsMany highly effective hacking groups associated with malware and advanced persistent threats (APTs) appear to lack an understanding of the technical exploits they use. They also fail to adequately test their exploits for effectiveness before unleashing them on their victims.

Gabor Szappanos of SophosLabs evaluated the malware and APT campaigns of several groups that all leveraged a particular exploit — a sophisticated attack against a specific version of Microsoft Office.

In a just-published technical paper, Gabor details how none of the groups he analyzed were able to modify the attack enough to infect other versions of Office, even though several versions were theoretically vulnerable to the same type of attack.

Snowshoe Spam is on the Rise – What can be done about it?

snowshoes02In our 2014 Threat Report, we noted that snowshoe spam was gaining popularity amongst spammers using new techniques to evade detection and sneak through loopholes in anti-spam laws. Over the last several months, we’ve noticed the volume of snowshoe spam continuing to build at a tremendous pace.

Snowshoe spam is essentially unsolicited bulk email. And it’s been effective, because like a snowshoe, it spreads the load across a large area. In this case, distributing spam across a huge range of IP addresses many of which are used briefly, and only once, sending out massive volumes of spam in very short bursts. The temporary aspect of these campaigns has also given rise to the term ‘hit-and-run’ spam. Naturally, this technique makes it challenging for filters to determine spam based on reputation.
