North Korea may be hacking banks across the world

North Korea may be hacking banks across the world

North Korea, allegedly behind the Sony Pictures cyberattack and more, could be behind a series of bank hacks across the globe resulting in tens of millions of lost dollars. Researchers with Symantec cite a recent trio of attacks that involved rare code seen in both the Sony cyberattack and earlier attacks against companies — including banks — in South Korea and the US. Assuming North Korea is behind the attacks, it would be a worrisome and exceedingly rare instance in which a nation-state is hacking global banks to steal money.

PC users should uninstall QuickTime for Windows ASAP

PC users should uninstall QuickTime for Windows ASAP

Most Windows users probably gave up on QuickTime as their media player of choice some time ago, but if for some reason you, or, shall we say, those who are less tech-savvy, still have it installed, you need to get rid of it right away. Two critical security flaws have been found in the aging Apple software that put PC users at great risk, so much so that even the Department of Homeland Security is advising people to uninstall the Windows version.

Petya ransomware finally has a fix, no need to pay ransom

Petya ransomware finally has a fix, no need to pay ransom

Late last month, a new kind of ransomware burst into the scene and threatened not just files but entire hard drives. Unabashedly calling itself "Petya", the ransomware targeted and encrypted entire hard drives instead of single files. Not to belittle the threat, it only took a week or two for the security community to come up with a solution. Although the process is rather involved, the good news is that you won't have to pay a single cent. At least not to the malware authors or its users.

Petya ransomware targets entire drives, not just files

Petya ransomware targets entire drives, not just files

Ransomware is quickly becoming the new darling among hackers looking to make a quick buck. Although it doesn't exactly jump from one infected computer to another, given how it works, it is actually more destructive and possibly more profitable than a common trojan or virus. We've seen recently what is probably the worst ransomware out in the wild. Now we're being told there's a potentially more destructive one as well. Called Petya, the ransomware tries to encrypt your entire hard drive for maximum damage and maximum profit.

TeslaCrypt 3 might be the most dangerous ransomware in the wild

TeslaCrypt 3 might be the most dangerous ransomware in the wild

Software developers usually, or at least should, quickly work to patch up security holes that could be exploited to the detriment of their users. It seems almost ironic but also expected that the very same mentality and process would be used by those who write malware in order to plug up the holes in their own software. The end result is, of course, a more robust malware that is even harder to crack and fight. That does seem to be the case with TeslaCrypt 3, the latest version of a ransomware that is now proving to be impossible to crack.

First Mac ransomware: Am I infected?

First Mac ransomware: Am I infected?

If you want to see your files again, cough up one Bitcoin. That's the message some unwitting Mac owners faced after accidentally installing malware on their computers, with the so-called ransomware encrypting their personal data and then charging them the equivalent of around $400 to retrieve it. Dubbed KeRanger, the malware - identified this weekend - is believed to be the first of its kind spotted in the wild.

First full OS X ransomware seen in Transmission BitTorrent app

First full OS X ransomware seen in Transmission BitTorrent app

When speaking of malware, Windows is usually the poster boy for an OS that gets infected a lot almost by nature. In truth, however, no operating system is totally bulletproof. Even Apple's OS X and iOS, usually considered to be tightly guarded silos, have their fair share of intrusions. This latest incident is one such example but this time the affected platform is Apple's much larger Mac OS X. Named by security firm Palo Alto Networks as KeRanger, the ransomware's damage is worsened by the fact that it infected even legitimate installers of the Transmission BitTorrent client.

How to avoid the new Netflix viruses and malware

How to avoid the new Netflix viruses and malware

Netflix scams are on the rise, so say the security crews at Tripwire and Symantec. How do you avoid such malware? How does your grandmother avoid downloading a virus?
