Skull virus Removal Guide
What is Skull ransomware virus?
Skull ransomware is another menace to the virtual community
Skull ransomware is a new virus that was discovered by Michael Gillespie. The virus is a file-encrypting program that appends a random extension to victim’s files and leaves How_To_Decrypt_Your_Files.html ransom note. Currently, it is unknown whether files locked by this ransomware can be decrypted
The ransom note contains an iframe tag[1] that leads to adartmark[.]com/blog_howto.html site. The note traditionally greets the victim with a standard message about encryption:
All your files have been encrypted!
If you read this file, that’s mean all your files was encrypted by the Skull Ransomware.
Surprisingly, the criminals provide even three Bitcoin wallet addresses. They demand $400 in Bitcoins[2] as a ransom, asking to write to their email address – skull.and.bones2017@protonmail.com. The victim should provide the following details:
- Transaction number;
- The wallet address from which the payment was made;
- Full computer’s hostname.
However, at the very end of the ransom note, criminals warn the victim that the Skull ransomware decrypter “can bug,” meaning that it might fail to work. We highly recommend you not to pay a ransom to fraudsters who might fail to provide you with a working decrypter.
To protect your computer from further cyber attacks and to continue using it again, remove Skull virus immediately. For that, we recommend using tools like ReimageIntego, although you can count on Malwarebytes as well. You can find more security-related tips and malware removal tricks on Novirus.uk site[3].
Ways to get infected
Regular computer users can unexpectedly become victims of ransomware and seek for Skull Ransomware removal after opening a compromised email attachment. Be extremely careful when browsing through your emails because one day you might come across a letter from cyber criminals.
There will be almost no signs of deception, whatsoever. You must be very vigilant to spot details that reveal falseness in such emails. One of the most common signs is mistakes all over the message body and in the subject of the email.
Another easy way to allow fraudsters to infect your computer is to use it without having the latest software updates. Software updates are released not only to improve programs by adding interesting and outstanding features but also to patch security vulnerabilities in them.
Without them, fraudsters can exploit old flaws in programs as soon as you visit a website containing an exploit kit. Such attacks can be prevented using anti-malware software and, as previously mentioned, applying software updates.
