A Firefox add-on has turned 12,500 users of the browser into a botnet which scours every page visited by infected users for vulnerabilities. The ‘Advanced Power’ add-on ensnared 12,500 PCs - and found 1,800 vulnerable websites for its unknown creators.
The assault by cybercriminals against big businesses continued this year -78% were attacked by outsiders, according to a report by Price Waterhouse Cooper. But small businesses - those with less than 50 employees - are rapidly becoming a target.
An international plot which would have turned huge numbers of PCs into “bricks” by using deeply buried malware was foiled by the NSA, according to an interview given to CBS by NSA director Keith Alexander. The attack could have "taken down the U.S. economy", an NSA official claimed.

The FBI custom-designs malware to snare suspects, a court has heard, and has been able “for years” to watch suspects through PC webcams, a court has heard. The teams operate "like normal hackers" - and rely on phishing and other criminal techniques.
APTs - or Advanced Persistent Threats - are the most menacing cyber attack there is, some say. Built to be stealthy, they penetrate networks, steal secrets - and vanish. 'Catching' one was a little like finding Bigfoot - but the much-hyped threat wasn't quite so scary up close...
As wireless technologies and electronic controls are increasingly built into cars, vehicles could become vulnerable to hackers - either stealing information, or injecting malware, a U.S. Senator warned - inspiring debate on how real this threat is.
Only weeks after Microsoft unveiled a global Cybercrime Center armed with new, hi-tech tools to combat crime, it announced it had carried out a global action leading to "significant disruption" of the Siferef botnet, a network controlling up to two million "zombie" PCs.
Once in a while we get to spend time analyzing malicious code that is not as widespread as other threats we've encountered. Here we analyze a targeted attack used in Taiwan and Vietnam - but is this 'APT' really that advanced?
A vulnerability in Android could allow attackers to “unlock” phones without cracking PIN codes - using malware to deactivate Google’s locks on handsets and tablets. The vulnerability can “turn off” all locks a user puts in place.
An audio communication system designed for ultrasonic underwater communications can be used to steal data - even from disconnected PCs in secure environments, by relaying it to the outside world from PC to PC through computer speakers, researchers claim.
An Iranian news agency has said that “malware worse than Stuxnet” may soon be unleashed, to “spy on and destroy the software structure of Iran’s nuclear program".
A look back at malware failures, malicious code that did not work out as well as the folks behind it had hoped. Can malware spread to quickly for its own good? Can malware authors ever test their wares well enough to work perfectly?
Filecoder, an unpleasant and virulent strain of ransomware is now spreading globally, with experts estimating that the gang behind it must be earning “millions”. The surging value of Bitcoin may be helping the criminals, experts say.
The company, E-Sports Entertainment, served up malware which used PCs to mine Bitcoins, an attack which earned $3,602. The malware was delivered surreptitiously alongside the company's official client.
Graham Cluley: AV shouldn’t just be something on your hard drive – it should be part of a global immune system
In the first of a series of guest blog posts AV industry veteran Graham Cluley voices his opinion on how security has changed - and the changes we all need to make for the future.
By the middle of May, users around the world started to receive messages from their contacts through different instant-messaging applications, such as Skype and Gtalk - an attack that showed off how age-old techniques can ensnare thousands of users. Here, we analyze this attack.
