What is AvosLocker Ransomware

AvosLocker is one of the most recent ransomware infections that encrypt personal files using both AES-256 and RSA-2048 algorithms. Along with this, the virus adds new .avos extension to each file that got encrypted. To illustrate, a sample file like 1.pdf will change to 1.pdf.avos and reset its original icon at the end of encryption. After all files have been configured with the new extension, users will see a text note called GET_YOUR_FILES_BACK.txt explaining how to recover the data.


Your files have been encrypted using AES-256.
We highly suggest not shutting down your computer in case encryption process is not finished, as your files may get corrupted.
In order to decrypt your files, you must pay for the decryption key & application.
You may do so by visiting us at hxxx: //avos2fuj6olp6x36.onion.
This is an onion address that you may access using Tor Browser which you may download at hxxxs: //www.torproject.org/download/
Details such as pricing, how long before the price increases and such will be available to you once you enter your ID presented to you below in this note in our website.
Hurry up, as the price may increase in the following days.
Message from agent: If you fail to respond in 4 days, the cost of decryption will double up and we will leak some of your data. In 10 days, we will leak all the data we have.
Your ID: ******** [redacted]

To do this, victims are instructed to visit the onion link via Tor browser, enter their personal ID, and therefore get the price for decryption suite to return their data. For now, this looks to be the only option available to recover your data completely. There is no third-party tool that has been successfully tested in decrypting AvosLocker files. It is worth noting that paying the monetary ransom may bear the risk of losing your money as well. This is why the best-case scenario in this situation is using backup copies of data. If you do not have any to capitalize on, you can still give it a try using third-party decryptors. This gives no guarantee for successful decryption but is still worth trying unless you have other options remaining. Follow our guide below to remove AvosLocker from your computer and learn some recovery methods.

How AvosLocker Ransomware infected your computer

There is no single method entitled to the distribution of malware like AvosLocker. File-encrypting programs are common to spread via e-mail spam, trojans, backdoors, keyloggers, untrustworthy downloads, fake software updates or “crackers”, unprotected RDP configuration, and many more to lengthen this list. E-mail is deemed to be the most popular distribution method. It implies sending spam letters bundled with malicious attachments from ostensibly legitimate addresses. Cybercriminals use nice-looking templates from legal campaigns (DHL, DPD, FedEx, Banks, etc.) to force people into believing they are trustworthy. Once trust has been achieved, users become more humble to click on the attached files. As a rule, extortionists attach PDF, Word, EXE, or JavaScript files as they are easy to reconfigure for storing a virus. After clicking on such, users are more likely to end up the victims of AvosLocker or various other malware that strolls around the web. The majority of people are negligent and inattentive, which costs them dozens of innocent files stored on a system. This is why it is important to keep your head on a swivel whilst browsing e-mail messages or any other content around the web. Below, we have dedicated a separate section meant to help you increase protection against such threats in the future.
