Horsia virus - How to remove

Scarab ransomware has got another malicious member in its family called Horsia.

What do you need to know about Horsia virus?

Horsia crypto-extortionist is a malware that will try to get victims’ money for unblocking the encrypted files. In this case the size of a ransom crooks are asking for is unknown (it says that it depends on how fast you will contact the hackers), but assuming from other crypto-virus examples it can be from around several hundred to a thousand US dollars. Hackers target personal files because victims are more likely to pay large amount of money for data they need and value the most.

Horsia malware gets into victims’ computers through vulnerable remote desktop protocol (RDP) configurations, spam email attachments, web injections, fake freeware downloads and infected update bundles or trojans. When the user clicks on the malicious attachment Horsia virus starts running scripts in the background and proceeds to complete ransomware installation. Crypto-infection scans infected operating system looking for potential targets, which usually  are the personal photos, videos, audio, documents, then Horsia uses AES algorithm to encrypt these files and modifies file names adding .[email protected] string to it. That makes user incapable of accessing file. Ransomware viruses, Horsia included, are really persistent and affect registry, so even if you reboot your system, crypto-extortionist will restart with it also, locking your data again.

Once the final encryption happens Horsia malware puts a text file format ransom note called ‘How To Recover Encrypted Files.txt’ in a noticeable spot on the desktop’s background, so the victim could read directions to restore files. Ransom note starts with telling the user that his files are all locked and to generate decryption key you have to pay a certain amount of money in crypto currency BTC. It gives more information on how to get Bitcoins and to message hackers to Horsia’s email –  [email protected].

Horsia’s ransom note states:
