Risk ransomware removal instructions

What is Risk?

Risk was discovered by Michael Gillespie and is a new variant of Dharma, a ransomware category infection. Like all the other viruses of this type, Risk is designed to encrypt files stored on an infected computer and keep them locked until cyber criminals receive a ransom payment for a decryption tool or key. The infection renames every encrypted file by adding the ".risk" extension. For example, "1.jpg" becomes "1.jpg.id-3A4E114C.[audit@cock.li].risk" (the extension contains an email address and a unique ID). Risk also creates a text file (a ransom message) called "FILES ENCRYPTED.txt" and displays a ransom-demand pop-up window.

"FILES ENCRYPTED.txt" contains an email address (audit@cock.li) to contact cyber criminals. A ransom-demand pop-up window contains a more exhaustive explanation regarding the situation: systems infected with Risk ransomware have arrived at this situation due to 'security problems'. It states that, as the files are encrypted, it is impossible to use them without contacting Risk developers via the email address provided. It goes on to explain that victims of Risk ransomware must contact the developers immediately, otherwise the cost of the decryption tool will be increased. Their demands are simple: victims must contact them using the email address and provide the assigned ID so that they can be identified. Once contacted, these criminals will then supposedly provide details about how to make a money transfer (in Bitcoins) and will provide a decryption tool as soon as the payment is made. They even offer free decryption of one file as a 'guarantee' that they can be trusted. In fact, no cyber criminals can be trusted, and this includes Risk developers. They commonly use algorithms that generate unique keys and store them on remote servers accessible only by them. Furthermore, they usually ignore victims even if the ransom demands are met. In this way, users are scammed. There are currently no tools capable of cracking Risk infection. Therefore, the best solution is to restore files using an existing backup.

Most ransomware-type viruses are very similar. Developers design them to encrypt files and make ransom demands. The main differences between these infections is the ransom (cost of  the decryption key/tool) and cryptography algorithm used for encryption. In any case, most of these viruses are 'uncrackable' and decryption without the involvement of cyber criminals is usually impossible, unless the ransomware is not fully developed or contains bugs/flaws. Therefore, maintain regular backups and store them on remote servers or unplugged storage devices. Some examples of other similar ransomware-type viruses are Bip, Lolita, GoodJob24, and Puma.

How did ransomware infect my computer?

The method that cyber criminals use to proliferate this ransomware is unknown, however, these infections are usually distributed using spam email campaigns, trojans, untrustworthy software download sources, and fake software updaters. Cyber criminals use spam campaigns to proliferate their viruses by sending emails that contain malicious attachments. These are often MS Office documents, executable (.exe) files, archive files such as RAR, PDF files, and so on. The main purpose is to present the email as legitimate and trick people into downloading and opening the malicious attachment (or web link). Torjans also proliferate ransomware infections. Trojans are malicious programs that, once installed, proliferate other viruses (thus causing chain infections). Cyber criminals also use various untrustworthy sources (such as peer-to-peer networks, freeware download or file hosting websites, etc.) to proliferate viruses. This is achieved by presenting infected files as legitimate - in these cases, users are tricked into installing viruses. Fake software updaters exploit outdated software bugs/flaws or download infections rather than the promised updates.

How to protect yourself from ransomware infections?

Study each received email before opening any attachment or web link. If the email is received from an unknown, suspicious email address, or simply looks irrelevant, ignore it and certainly do not open the attachment or link. The safest way to download software is using official and trustworthy sources. Other sources, such as third party downloaders, unofficial websites, and so on, should not be used. Keep your software updated, but do this using implemented functions or tools provided by the official software developers, and not third party updaters. Having reputable anti-spyware or anti-virus software installed is also paramount. These tools detect and eliminate viruses (or other infections) before they can do any damage. If your computer is already infected with Risk, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
