BlackHole RAT Mac OS X backdoor Trojan virus mimics password prompt

A new backdoor Trojan virus that targets Mac OS X has emerged, Sophos reports. Interestingly, the new virus, which is called BlackHole RAT (or OSX/MusMinim-A in virus definition speak), is a variant of the 'legitimate' Windows Trojan DarkComet-RAT. Fortunately, the virus doesn't seem to be very malicious. It allows a remote controller to reboot or shutdown an infected computer, or pop up a...

Acrobat Reader X delivers on security promise

Over at the Naked Security blog, Sophos Labs' Paul Baccas posted his first encounter with PDF spam using Adobe Reader X -- which Adobe promised would feature an improved set of security features. Baccas was examining a new spam campaign which aims to trick users into opening a malicious PDF, first opening it in Reader 8 and then in Reader X. When opened in the old version, the PDF attack...

Sophos Labs releases free antivirus for Mac

There was a time when Mac users enjoyed "security by obscurity." Because of the much smaller number of Mac users in the world, malware authors didn't bother targeting Apple desktops and laptops. Those days are long gone, however, and new threats that put Mac users at risk are appearing all the time. Fortunately, there are now plenty of good antivirus options for Mac users to combat the rising...

Sophos polls again, claims 93% want opt-in sharing on Facebook

Security firm Sophos has been all over the recent Facebook sharing shenanigans. The company took a little heat over their last poll, which seemed to claim that 60% of Facebook users were considering leaving the site over privacy concerns. Other blogs ran wild with the headline -- making it appear that a mass exodus was on the way and completely overlooking the fact that they had under 1,600...

Facebook users hit by password-stealing attack: here's how to stay safe!

The security pros at Sophos Labs and McAfee have noticed a disturbing increase in Facebook phishing attacks lately. Facebook is a juicy target for this type of attack. Why? For starters, there are 350 million + users to go after. On top of that, many are less computer-savy users (like your parents and mine, teenagers, etc.) who may not be familiar with malware and how to protect themselves....

Bit.ly to begin checking short URLs for malicious code

I'm a fan of just about anything which helps make the web a little safer for my friends, family, and customers. So I was excited to read that Twitter's favorite link shortening service, bit.ly, is working to check every URL they process for malicious code. With about 40,000,000 links in their database and a firmly-established position as the top short link provider on Twitter, this is great...

Over 40 percent of Facebook users invite identity theft by blindly accepting friend requests

In the shocking, yet not really unexpected, results of an investigative study by Sophos, 41% of Facebook users blindly accept friend requests from unknown contacts. The probe by Sophos also looks into what data we make readily available. Scarily, almost all of us display our full date of birth and email addresses -- two pieces of information which make identity theft incredibly easy, especially...

Satan gets frostbite, security providers form coalition to fight malware

Remember the other day when I said I wouldn't hold my breath waiting for the security providers join forces for the greater good? Sophos' Graham Cluely has this morning announced the formation of the Industry Connections Security Group under the umbrella of the IEEE Standards Association's Industry Connections program. Initially the group includes Sophos, Microsoft, Symantec, McAfee, AVG, and...

Full power to the deflector shields! Sophos releases Klingon Antivirus

One thing that I always like to see in a corporate entity is the ability to have a little fun from time to time. If I was going to give an award for "Best Comedic Performance by a Software Vendor," it would go to antivirus developer Sophos, hands down. Why? For their brand-new Klingon antivirus application. The program is no joke - it's real Sophos AV, but it may not be a real benefit for you if...

Windows trojan horses outnumber viri and worms 4 to 1

Anti-virus maker Sophos recently released its 2007 Security Threat Report, a State of The Union for desktop security issues which, given a full read-through makes you shudder to think of the malware and nasties your PC could run afoul of any given time. According to the report, Windows Trojans, which sometimes go undetected for long periods of time, outnumber viruses and worms by a factor of 4 to...
