You might think that the massive number of security breaches that have happened in recent years would push corporate giants and medical facilities out there to take a look at their own security and ensure that their networks are protected. We are only a few months removed from the massive attack that breached Equifax... Read more...
Microsoft has found a way to fight back against the growing threat of ransomware, a devious type of malware that encrypts files and folders on a victim's PC and then demands a ransom—oftentimes in Bitcoin due to its anonymity—in exchange for unlocking the user's data. Some ransomware strains even come with a timer... Read more...
This has been a bad year for wide-scale ransomware attacks, where malware encrypt a user's computer and demands payment to unlock the machine. The two major ransomware attacks that have happened in 2017 include WannaCry and ExPetr (or Petya and NotPetya as they were also called). The hackers behind WannaCry cashed out... Read more...

Cyber crooks have found a new way to ruin a person's day with ransomware. Traditionally most ransomware encrypts a victim's storage device and then demands a ransom in order to unlock the files.

Here's something you don't see too often: a ransomware creator unearthing the master decryption key for public consumption.

Over the past few years, one of the most prevalent types of malware has been ransomware - an infection that automatically locks down your sensitive data, and then makes you buy it back with your hard-earned cash.

There are no days off in Redmond, at least not for Microsoft.

What makes this new strain... Read more...
Following last month's WannaCry attack, it looks as though another ransomware outbreak is quickly spreading around the globe.

Getting on-board with an operating system like Windows 10 S may be difficult for some users. Only a certain type of user would purposefully opt to use a whittled-down, locked-down OS by choice, but for the security conscious, it makes a lot of sense. After all, 10 S is still Windows -- it's just supposed to be safer. That's been Microsoft's Read more...

The notion that Mac systems are immune to malware is just plain wrong. Sure, Macs might be less susceptible to malware than Windows-based PCs, but they are certainly not exempt from security threats. Proving otherwise, two different security outfits have put out warnings about separate threats targeting Mac users. One... Read more...
Now that the dust has settled on a global ransomware outbreak that could have been much worse than it ended up being, we can all breathe a sigh of relieve.

Microsoft stopped supporting Windows XP several years ago, though because some users and businesses (including government agencies) are still clinging to the legacy operating system, it has been known to release patches for more serious security threats.

Last fall, we reported on a somewhat humorous report of a mere "reply all" email that managed to bring down email servers of the UK's National Health Service.  Unfortunately, we have something a bit more severe to report on today: an all-out cyberattack against the NHS. At some point today, doctors at NHS had to... Read more...
