Huylock – Ransomware
The Huylock stands for a ransomware-type infection. The virus comes from the MedusaLocker ransomware family. Huylock was elaborated specifically to encrypt all major file types. Once the file is encrypted people are unable to use them. Huylock adds the “.huylock” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Huylock, will be renamed into “myphoto.jpg.huylock“. As soon as the encryption is finished, Huylock places a special text file into every folder containing the encrypted data.The message given by Huylock text file asking for the ransom is absolutely the same as the statements given by other ransomware representatives coming from the MedusaLocker clan. It literally discusses that the info is encrypted and that the only way to restore it is to use a a distinct decryption key. Unfortunately, this is definitely true. The sort of cryptography mechanism applied by Huylock is still not appropriately examined. Still, it is absolutely specific that each victim may be given the specific decryption key, which is completely distinct. It is impossible to bring back the files without the key available.
Another trick of Huylock is that the victims cannot gain access to the key. The key is kept on a specific server run by the frauds related to Huylock ransomware. To get the key and recover the important information people need to pay the ransom.
Huylock encrypted your documents, but that might not be the only damage done to you. The ransomware might still be hidingon your computer. To identify whether this holds true, we suggest downloading GridinSoft Anti-Malware.

Nonetheless, regardless of the asked for amount, people need to stay away from paying the virus. Cyber frauds are unfair, so they tend to totally disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom usually does not provide any positive outcome and people just lose their money for nothing.
We highly encourage that you do not contact these crooks and absolutely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Huylock ransomware and to recover the data data for free. Hence, the just best decision is to recover the lost data from the available backup.

Keep in mind that the internet is now overwhelmed with threats that look similar to Huylock ransomware. Harmful programs of such kind are normally elaborated to encrypt crucial data and to state the need prior to the user to pay the ransom. The peculiarity of all such ransomware threats is that all apply a similar algorithm to generate the unique decryption key for information decryption.
Thus, as long as the ransomware is still being developed or has some hidden bugs, by hand recovering the information is just not feasible. The only method to prevent the loss of your essential information is to regularly create backups of your important information.
Bear in mind that even if you create such backups, they must be put into a special storage utility not connect to your main PC. You may use the Memory Stick or external hard disk drive for this purpose, or refer to the help of the cloud storage. If you keep your backup files on your common system they may be encrypted together with other files, so it’s certainly not a good storage place.
How did ransomware infect my PC?
There are several methods used by online scams to distribute Huylock ransomware. Even though it is uncertain how exactly Huylock injects your computer, there are some leaks through which it may infiltrate the system:
- integration with third-party software application, especially freeware;
- spam e-mails from unknown senders;
- sites rendering free hosting services;
- pirated peer-to-peer (P2P) downloads.
Often Huylock virus may exist as some legitimate software, for instance, in the pop-ups instructing users to implement some essential software application updates. This is the common technique used by online frauds to persuade people into downloading and installing Huylock infection manually, by methods of their direct participation in the installation process.
In addition, the criminals may refer to different e-mail spam methods to inject destructive codes into systems. So, they may refer to to sending unsolicited spam emails with tricky notices promoting users to download the attachments or click on certain download links, for example, the ones motivating users to open some receipts, documents, tax reports or invoices.
Needless to mention, opening such documents or clicking on such dangerous links may seriously harm the system. Fictitious Adobe Flash Player update alerts may result in Huylock virus injection. As for the cracked software, these illegally downloaded programs may also contain destructive codes causing Huylock secret installation. Finally, injection of Huylock may happen by ways of Trojans that secretly get injected into the system and install malicious tools without the user’s consent.
Is there any way to avoid the injection of Huylock ransom virus?
Even though there is no 100% guarantee to avoid your computer from getting infected, there are some pieces of recommendations we wish to show with you. First off, be very cautious when you browse the web and specifically while downloading totally free programs. Keep away from opening suspicious email attachments, especially when the sender of the email is not familiar to you.
Bear in mind that some freeware installers may consist of other unwanted utilities in the bundle, so they may be malicious. Make certain that your current antivirus software and your entire OS is always duly updated.
Of course, downloading pirated software is illegal and may result in necessary damage to be made for your PC. Hence, stay away from downloading cracked software.
