Move over WannaCry, there's a new Ransomware in town | IntelliTeK Managed IT Services Sydney Australia

Adylkuzz is a CoinMiner malware, which means that it employs – without user consent – machine resources to mine coins for virtual currencies. It appears to exploit the same vulnerabilities as the WannaCry ransomware did but in a more stealthier fashion.

On paper WannaCry was the more damaging in the sense that it threatened the victim with data loss and extortioned money from its victims. Adylkuzz on the other hand is a lot less in your face and operates in the background, using the victims machine to mine crypto keys to turn it into something with monetary value. What that means is the malware consumes resources on the machine, such as using CPU cycles.

So whoever is behind the attack creates an army of machines, with each one running a program in the background of the machine which link up with other machines infected and altogether create small amounts of cryptocurrency. These programs mostly go unnoticed by the computer’s owner. The bigger problem here is that mini crypto currency is one thing, once a victims computer has been infiltrated it could lead to something far worse.

There’s nothing official about who is behind WannaCry or Adylkuzz, but there is speculation that WannaCry was related to North Korea due to the software behavioural characteristics sharing similarities to the Sony attack in 2014 — which was attributed to DPRK. Since Adylkuzz is a newly discovered ransomware and isn’t as immediately destructive as WannaCry was, there is very little to go by surrounding its origins. But the public must stay alert and carry on keeping a close eye on emails and in this instance with CPU usage.

The importance of downloading update patches cannot be at its highest. The truth is, WannaCry and Adylkuzz were fixed/patched two months ago. The main reason why WannaCry came to life on May 12, 2017 was that not every machine on the planet were up to date with their patches. Microsoft addressed the WannaCry malware back in March 2017, but organisations around the world – small businesses to large corporations – still hadn’t updated their Windows and that’s where it all went haywire.
