.harma (Ouroboros) ransomware removal instructions
What is .harma (Ouroboros)?
Discovered by malware researcher S!Ri, .harma (Ouroboros) is a ransomware-type malicious program belonging to the Ouroboros malware family. Systems infected with it have their data encrypted and victims receive ransom demands for the decryption tools/software. During the encryption process, all affected files are retitled with the ".harma", this extension has been used by another ransomware from the Dharma family. To elaborate how files would appear following encryption, a filename like "1.jpg" would appear as "1.jpg.harma". After this process is complete, two files - "INFO.exe" and "ReadMe.txt" - are dropped onto the desktop, they contain the ransom notes.
The text file informs victims that their data has been encrypted. To restore the files, users are instructed to establish contact with the ransomware's developers via the email addresses provided. The title of their letters must be the unique ID and contain their personal keys. The pop-up window (opened by "INFO.exe") is a more detailed ransom note. It repeats the information written in "ReadMe.txt" and adds that victims can test decryption by sending one encrypted file to the cyber criminals behind .harma (Ouroboros). This test file cannot be larger than 1Mb and/or contain valuable information (e.g. database, backup, large excel sheet and similar). The ransom size is not stated, however it must be paid in Bitcoin cryptocurrency. This note also lists links to websites detailing how to and from where to acquire Bitcoins. It warns users that renaming the compromised files and/or attempting decryption with third party software - can lead to permanent data loss. Unfortunately, it is true that in most cases of ransomware infections - decryption is impossible without the interference of the criminals responsible. It might be viable, if the malware is still in development and/or has bugs/flaws. Whatever the case, it is strongly advised against meeting the ransom demands of cyber criminals. Often, despite paying - victims do not receive the promised decryption tools/software. Therefore, not only do their files remain encrypted but they also experience significant financial losses. To prevent .harma (Ouroboros) ransomware from further encryptions, it has to be removed from the operating system. However, removal will not restore already affected data. The sole solution is recovering it from a backup, if one was created prior to the infection and was stored in a different location.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
Ragnarok, Devos, Nosu are a couple examples of other ransomware. Malicious programs classified as such are designed to encrypt data and demand payment for the decryption. The crucial differences between them include: the cryptographic algorithm they use (symmetric or asymmetric) for the encryption and the ransom size. The latter typically range between three and four digit sums (in USD). Digital currencies (mainly cryptocurrencies) are preferred by cyber criminals, due to transactions of them being difficult/impossible to trace. To ensure data safety, it is recommended to keep backups in remote servers and/or unplugged storage devices.

How to protect yourself from ransomware infections?
Suspicious and/or irrelevant emails should not be opened, especially ones received from unknown addresses. Any attachments (or links) found in dubious mail - must never be opened, as doing so can trigger an infection. It is recommended to only use official and verified download channels. All programs should be activated and updated with tools/functions provided by legitimate developers. Illegal activation tools ("cracks") and third party updaters carry a high risk of malware installation, therefore they are advised against use. It is important to device/user safety to have a reputable anti-virus/anti-spyware suite installed and kept updated. This software is to be used for regular system scans and removal of detected/potential threats. If your computer is already infected with .harma (Ouroboros), we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

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 .harma (Ouroboros) 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.
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.
