Kraken Ransomware Emerges from the Depths: How to Tame the Beast

Look out, someone has released the Kraken — or at least a ransomware strain named after it. Kraken Cryptor ransomware first made its appearance back in August, but in mid-September, the malicious beast emerged from the depths disguised as the legitimate spyware application SuperAntiSpyware. In fact, the attackers behind the ransomware were able to access the website superantispyware.com and distribute the ransomware from there.

So how did this stealthy monster recently gain more traction? The McAfee Advanced Threat Research team, along with the Insikt group from Recorded Future, decided to uncover the mystery. They soon found that the Fallout Exploit kit, a type of toolkit cybercriminals use to take advantage of system vulnerabilities, started delivering Kraken ransomware at the end of September. In fact, this is the same exploit kit used to deliver GandCrab ransomware. With this new partnership between Kraken and Fallout, Kraken now has an extra vessel to employ its malicious tactics.

Now, let’s discuss how Kraken ransomware works to encrypt a victim’s computer. Kraken utilizes a business scheme called Ransomware-as-a-Service, or RaaS, which is a platform tool distributed by hackers to other hackers. This tool gives cybercriminals the ability to hold a victim’s computer files, information, and systems hostage. Once the victim pays the ransom, the hacker sends a percentage of the payment to the RaaS developers in exchange for a decryption code to be forwarded to the victim. However, Kraken wipes files from a computer using external tools, making data recovery nearly impossible for the victim. Essentially, it’s a wiper.
