Hackers Target Email, Blogs, Social Networking Sites

In a report by security firm Websense , an alarming rise in the growth of malicious websites was identified in 2009 as compared to 2008 – almost 225 percent. The study also found an increased focus among hackers and spammers on targeting social media sites such as blogs and wikis. Social media or so-called Web 2.0 sites allow user-generated content , which can be a source of vulnerability. Researchers identified that up to 95 percent of user-generated comments to blogs, chat rooms, and message boards are spam or malicious – linking to data stealing sites or to downloads of malicious software . Email also continues to be a target for malicious activity with tens of thousands of Hotmail , Gmail and Yahoo! email accounts hacked and passwords stolen and posted online in 2009, which resulted in a marked increase in the number of spam emails.

Mozilla Firefox Add-Ons Download Site was Harboring Malware

Mozilla , the organization behind the popular Firefox browser disclosed that two add-ons available for download on its website were vectors for Trojans that could compromise users’ computers. Add-ons allow users to extend and enhance the capabilities of Firefox beyond the default install. Normally they are scanned for malware before being uploaded onto Mozilla’s website, but apparently two of them managed to slip through Mozilla’s automated scans. The infected add-ons are Version 4.0 of Sothink Web Video Downloader and all versions of Master Filer. Mozilla has since updated their scanning process, but as part of our ongoing security watch we are vigilant in continuously protecting our customers under our Managed Services program from malware – you can rest easy. When managing your systems on your own, it’s highly advisable to be vigilant with security and always use antivirus software – even when downloading and using software from legitimate sources. If you have downloaded these Firefox add-ons, uninstalling them does not remove the trojans that they carry, and you’ll need to use antivirus software to remove any malware on their system. Need more information or help? Call us and we will be glad to assist you.

Beware the Kneber Botnet

A malicious piece of software making the rounds of news websites this week is believed to be behind the compromise of over 75,000 systems in over 2,500 international organizations – many of which are government agencies and large Fortune 500 companies. Called the Knebner botnet after the name in the email used to register the initial domain used in the campaign to propagate the malware , the software infects computers and captures user login access to online financial services such as Paypal and online banks, social networking websites such as Facebook, and email. Infected computers can be centrally controlled from a master computer, which presumably harvests the data captured for nefarious means. The Knebner botnet itself is not new. It’s based on the ZeuS botnet, and has gained prominence lately because it’s slipped under the radar of so many organizations. However, there are ways to prevent compromises from botnets – one of which is to have a proactive security system and policy in place. Our Managed Security customers have this assurance in place since we continuously protect their system from botnets and other malware. If you’re not sure that you’re protected, talk to us today.

Beware of Vulnerabilities in Windows and Office

Microsoft recently released a number of security bulletins and patches addressing vulnerabilities in Windows and Office that are of high risk to users. It’s widely believed that many will be exploited by hackers within the next 30 days. One of them could potentially allow hackers or malware authors to easily compromise systems by tricking users to download malicious AVI-formatted files. Others require nothing more than just visiting a website. Another specifically targets Powerpoint Viewer 2003, and opening a malicious .ppt file could affect your system. This latest round of patches and vulnerability updates is really nothing new – although the sheer number made public in one day is notable. This highlights the need for a comprehensive security policy, because vulnerabilities do exist in even the most mundane or old versions of software. Customers under our Managed Services plan can rest easy since we monitor and update their computers as soon as these patches and advisories are released.

Mariposa Botnet Masters Arrested

Spanish authorities report that they have arrested the masterminds behind a string of online criminal activities using the botnet dubbed Mariposa. Mariposa is the original name of a commercially distributed Do-it-Yourself malware kit, sold online for 800/1000 EUR for “wannabe” hackers.  Along with the arrest, authorities seized sensitive data belonging to about 800,000 users in 190 countries, gathered from an estimated 12M+ infected host computers on the Internet. What’s particularly interesting is that the cybercriminals arrested were not themselves the author of the malware, nor were they any more techincally adept than many ordinary users. They simply had access to malware widely available on the Internet, and were able to conduct a crime of such a wide scale and reach. This illustrates that it’s become easier for many cybercriminals to conduct their nefarious deeds online, and highlights the need for more vigilance on the part of law-abiding netizens in keeping their network secure from hackers and malware.
