Hrosas ransomware – a Djvu family member that extorts victims for a ransom price up to $980

Hrosas ransomware
Hrosas ransomware is a file encrypting threat that belongs to the Djvu ransomware family

Hrosas ransomware is a ransom-demanding cyber threat that is a sibling of the Djvu ransomware family. The rewards of this discovery go to Michael Gillespie who always updates his findings on his Twitter account. .horsas is the appendix which appears to each file after the data encryption process. Later on, the victim receives the same message which comes with every Djvu variant, READ_ME.txt. As usual, Hrosas virus urges a ransom price of $480 which doubles if no contact is shown in a three day period. The cybercriminals provide two email addresses through which victims are supposed to write them: vengisto@firemail.cc, and vengisto@india.com. Sadly, the main goal of these crooks is to extort as much money as possible, so there are no guarantees that you will receive the decryption tool after the payment transfer.

Hrosas ransomware uses unique encryption ciphers to lock up most of the data files that are stored on the infected machine. Usually, crooks use codes such as AES,[1] RSA, SHA, and similar ones which successfully encrypt targeted files. Once this happens, the decryption keys are stored on remote servers so that nobody can reach them.

Hrosas ransomware is a much sneakier cyber threat then it might appear to be from the first view. There are other damaging activities that are being performed by this virus. This ransomware displays a fake Windows Update window and also modifies the “hosts” file in order to prevent users from accessing security-related networks and sources. 

However, one of the most dangerous activities that Hrosas ransomware performs is the secret installation of the notorious AZORult Trojan horse. This type of malware is designed to steal various sensitive details about the user and misuse them for illegitimate purposes. Also, trojans overuse system resources, force programs to crash, and provide hackers with remote access to the targeted system.

As you can see, file encryption might not be the worst thing that might happen. The sooner you take actions to remove Hrosas ransomware, the more the damage can be avoided. Our suggestion would be to scan the entire computer system and search for malware-infected locations. That can be done by installing and launching a computer tool such as Reimage.

Hrosas removal is a necessary process if you want to unlock your files. Rather than paying the demanded price and risking to get scammed, you can terminate the virus and try some third-party tools for unblocking your data files and documents. Make sure that the ransomware is no longer running on your machine and take a look at the data recovery software that we have provided at the end of this page.

Distribution methods of ransomware infections and their malicious payload

According to Virusai.lt experts,[2] ransomware viruses are these sneaky threats that appear on the targeted computer system unknowingly, however, usually, it still requires the user's interaction. Mostly, ransomware sneaks into the machine through infected email messages where malicious payload is hidden in a hyperlink or attached document.

We offer to investigate every received email message that you were not expecting to find in your inbox. If there are some attachments clipped to the email, use antivirus or antimalware software to scan that component. Moreover, if you find rogue messages in your spam section, better delete them all as nothing important or official is sent here.

Continuously, various malware forms, including ransomware threats can be found in infected hyperlinks or advertising notifications. Keep a distance from third-party networks and avoid potentially dangerous content. Peer-to-peer networks[3] include unprotected downloading hyperlinks that might also carry the ransomware-related payload.

Hrosas ransomware should be removed from the system to prevent further damage

You should remove Hrosas virus immediately to avoid the possible installation of a Trojan horse. Also, if you do not eliminate the threat, you will not be able to use data recovery software for data restoring. Use reputable antimalware such as Reimage, Malwarebytes MalwarebytesCombo Cleaner, or Plumbytes Anti-MalwareMalwarebytes Malwarebytes to scan the entire computer system and eliminate all malware traces.

Hrosas removal should be carried out by paying big attention and checking the entire Windows Computer system from malicious content.
