Losers ransomware removal instructions

What is Losers?

First discovered by malware security researcher, Toffee, Losers is a new variant of ransomware-type viruses Nemesis and Cry36. Once infiltrated, Losers encrypts stored data and appends names of encrypted files with the ".losers" extension. Note that, in some cases, Losers is named Damoclis Gladius Ransomware and appends the ".damoclis" extension. Therefore, "sample.jpg" is renamed to either "sample.jpg.losers" or "sample.jpg.damoclis". After successfully encrypting files, Losers changes the desktop wallpaper and creates an HTML file ("HOWTODECRYPTFILES.html"), placing it in each folder containing encrypted files.

The HTML file contains a message informing victims of the encryption and encourages them to visit a Tor website to restore encrypted data. After visiting this site, users are encouraged to enter their personal ID, after which they are automatically connected to a live chat with developers of Losers. These people then demand a ransom payment in exchange for decryption. The cost is the equivalent of $500 in Bitcoins. It is currently unconfirmed which encryption algorithm (symmetric or asymmetric) Losers employs, however, in any case, decryption requires a unique key, which is stored on a remote server controlled by cyber criminals. Although you may be encouraged to pay, cyber criminals cannot be trusted. These people commonly ignore victims, once payments are submitted and there is a high probability that you will be scammed. You will lose your money and support cyber criminals' malicious businesses. For these reasons, we strongly advise you to ignore all requests to contact these people or pay any ransom. Unfortunately, there are currently no tools capable of restoring files encrypted by Losers - the only solution is to restore files/system from a backup.

Research results show that all ransomware-type viruses are very similar. As with Losers, Crypto Tyrant, Bad Rabbit, Ordinal, Blind, and many others, also encrypt files and make ransom demands. Usually are just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Unfortunately, most use algorithms (e.g., RSA, AES, etc.) that generate unique decryption keys. Therefore, unless the malware contains bugs/flaws (e.g., it stores the key locally or is hard-coded), file decryption manually, without involvement of developers (contacting these people is not recommended) is impossible. For these reasons, ransomware-type viruses such as Losers present a strong case for maintaining regular data backups. You data backups should be stored on an external (unplugged) drive or a remote server (e.g., Cloud).

How did ransomware infect my computer?

Cyber criminals proliferate ransomware-type viruses in various ways, however, the most popular five are: 1) fake software update tools; 2) trojans; 3) peer-to-peer [P2P] networks; 4) unofficial software download sources, and; 5) spam emails. Fake software updaters exploit outdated software bugs/flaws to infect the system. Trojans open "backdoors" allowing malware to infiltrate the system. P2P networks and other third party download sources (free file hosting websites, freeware download websites, torrents, eMule, etc.) often present malicious executable files as legitimate software, thereby tricking users into downloading and installing malware. Spam emails often contain malicious attachments (such as MS Office documents, JavaScript files, etc.) that, once opened, download and install malware. The main reasons for computer infections are careless behavior and lack of knowledge.

Threat Summary:
NameLosers virus
Threat TypeRansomware, Crypto Virus, Files locker
SymptomsCan't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.
Distribution methodsInfected email attachments (macros), torrent websites, malicious ads.
DamageAll files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.

How to protect yourself from ransomware infections?

To prevent ransomware infections, be very cautious when browsing the Internet. Keep installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite. Note that third party updaters (and download/installation tools) often install malicious programs and, therefore, should not be used. Carefully study all steps (especially the "Custom/Advanced" settings) of the download/installation processes and decline offers to download/install additional programs. Never open files received from suspicious emails - delete these emails without reading. The key to computer safety is caution.

4. In the opened window, click "Next".

restore system files and settings

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Losers ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Losers ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Losers are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by Losers, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Losers ransomware.

Note that Windows 10 Fall Creators Update includes the "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to obtain this update and add an additional protection layer from ransomware infections.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
