What is Skull HT ransomware? And how does it execute its attack?

Skull HT ransomware is another file-encrypting Trojan malware which first emerged on November 2, 2017. According to the researchers who first analyzed this ransomware, Skull HT’s malicious payload is delivered using a specially crafted corrupted PDF file which is actually an executable file. The fake PDF file is entitled “The Art of Amazon Carding.pdf.exe which is attached to spam emails.

Skull HT ransomware, as it name suggests is based on the open source platform called, HiddnTear. And it had gotten its name from the custom desktop background it applies on the infected computer which is an image of a forest with railroads and a green skill that stood out. Currently, this new ransomware is known to target English-speaking users. During its attack, it searches the entire computer drive looking for certain file extensions to target such as images, audio, video, documents, database and other user-generated files that may be of importance. Skull HT ransomware is known to use the AES 256 cipher in encrypting its targeted files. It also appends the .locked extension, i.e. image1.jpg becomes image1.jpg.locked. After that, the ransom notification is loaded as the new desktop background image as well as a text files named READ_ME.txt – both desktop background and the text file contains the following message:

“Your computer has been LOCKED

Your personal files have been encrypted.

There is no need for you to panic and pay the ransom as the files that are encrypted by Skull HT can be recovered using the Windows Previous Version feature which restores the files using their shadow volume copies. And besides that does not mean that if you pay the ransom, you get to have your files back in an instant – that’s where you’re wrong as these crooks are not exactly known to keep their promises.
