With the popularity of Android on the continued rise, the number of malware infected apps have increased as well, and while malevolent software is still mostly infecting traditional computers, mobile device owners now have to accept the fact that it will only get harder to keep their phones and tablet computers free from harm, unless they take precautionary actions.

Rootkit Woes

Rootkits are a particularly nasty form of malware, in-so-far as once they install, they cover their tracks and make it very difficult to find them, let alone uninstall. A case in point is the particularly nasty Win32:Popureb.E variant bootkit (so-called because it uses the master boot record (MBR) to hide itself), which Microsoft announced on their technet blog that not only is a complete reinstall of the OS necessary to remove the malware, but the MBR also needs to be fixed before the reinstall takes place, something that might be beyond the capabilities of inexperienced users. This problem is exacerbated further due to their being no one simple process to clean the MBR, but differing processes, dependent on the operating system you are using, using either the Windows Recovery Console and BOOTREC.exe to fix the MBR or other tools, post XP (Detailed instructions here: for Windows XP, Windows Vista and Windows 7). But what can you do to prevent rootkit infections in the first place?

Russia - The New #1 for Malware

Help Net Security reports that Russia has overtaken the USA as the king of malware distribution via spam according to research undertaken by Kaspersky Labs. With spam messages making up to 80% of all email traffic, we are all at risk from everything from phishing scams (where PayPal details seem to be the most coveted) to direct malware infection via cleverly crafted links in emails, often to rogue sites looking like real internet properties. So, what can we do to stay safe online?

The Problem With Flash

Adobe, it seems, is a victim of being a huge success: having issued two out-of-band updates (emergency fixes, outside of the usual patching release cycle) within 9 days of each other. The single biggest problem with Flash is that it is ubiquitous on the web, and installed on so many machines, and not just Windows PCs, making it an important cross-platform infection vector. While, absolutely, Adobe has to take a large part of the blame, and they are addressing the issue by getting better and better at security fix responses, the simple huge popularity of the technology has made it a core target of hackers and malware pedlars. One of the core problems, from a security perspective, however, is that, according to this computerworld article, fixes can take time (from 72 hours and up), and during that time users are not only vulnerable, but have no real indicators that they are vulnerable, meaning, depending on the exploit, hackers and malware authors have carte blanche on the user machine until the problem is fixed, and the user probably has no indication idea of this. So, what can you do?

Search Engine Poisoning

Another day, another acronym to remember. This one is important, though, as the prevalence of SEP is on the increase. Security firm Imperva released a report on search engine poisoning, which, in summary, is a manipulation of search engine result, often using black-hat SEO techniques, to display results that contain references to malware delivering sites - which might either spoof a user to download malicious files, or use so-called drive-by techniques to instigate a download on poorly configured systems. The report suggests various techniques can be used in the SEP attack, including:

Microsoft Patches Exfiltration Flaw in Hotmail

Trend Micro, via Help Net Security, has reported a flaw in Microsoft's Hotmail service that allows exfiltration via a script, enabling attackers to syphon off user contact information and messages from a users account. The good news is that it's patched already. The next bit of good news is that if a user logged out just after infection, the session for the hotmail account was ended, which stopped the exploit cold. The ingenuity of the attack was such that it did not require a user to actually click on a link to work or download something, but just to open a specially crafted email which in turn would allow a script embedded into the email to do the dirty work. The attack looks like it was specifically targeted, and used variables used by hotmail itself to work. It is unknown at this time how many users might have been affected by the exploit, but kudos to Microsoft for the quick fix.

Beware Fake VirusTotal Site

The securelist blog has reported that they have found a fake website pretending to be VirusTotal, the popular open-to-the-public malware submission and multi-engine analysis site. Visiting the site might get you infected (depending on your security settings) via a javascript drive-by exploit that will download a malicious java exploit that in turn will set up your system as part of a botnet. Such botnets are used to perform DDoS (Distributed Denial of Service) attacks and to deliver spam messages. To avoid infection, consider the following as the minimum you should be doing to protect you and you valuable data:

The RogueAV Risk

April saw the largest increase in detectable malware according to Help Net Security, up 26% on the previous year, with 73,000 new variants of threats being released daily. While this is worrying in and of itself, a particularly aggressive campaign has been waged against users in the form of RogueAV (and variants). The scammers promoting this particular form of malware have been very adept at using social techniques, and social media, to promote these "products". What can you do to protect yourself?

Zeus Source Code Leaked

Back in February, the infamous Zeus Trojan source code was known to be made available on underground hacking and tools forums. At that time the cost of the code was around $100,000. Several weeks later, the price was just $5000. Now it's available for free. Peter Kruse broke the story on the CSIS blog, with InfoSecurity (UK) following up more in-depth two days later. So what's the story, and why is it important?
