Yoqs is file-encrypting ransomware that prevents access to your text files, Excel tables, videos and photos by encrypting them. It marks the encrypted files with the “.yoqs” extension. Then Yoqs ransomware adds a ransom note (readme.txt) to each folder. In this note, you can see the instructions to pay the ransom ($490-$980 in Bitcoin) to a certain Bitcoin address. The AES-256 or RSA-1028 cipher it uses to encrypt the documents is not decryptable with contemporary computers. Even quantum computers that already exist will spend hundreds of years to find the decryption key.

It ciphers all widespread file formats- .psd, .doc, .docx, .xls, .xlsx, .pdf, .jpeg, .png, et cetera. When these files are located, the ransomware will cipher them and change their extension to “.yoqs” so that you understand what happened.

After the Yoqs ransomware encrypted the files on your PC, it will generate the last “readme.txt” file on the main screen. Besides the ransom payment instructions, the victims also see the email addresses to contact the crooks – helprestoremanager@airmail.cc and manager@mailtemp.ch.

How did the Yoqs ransomware get on my computer?

The Yoqs ransomware spreads by placing websites to download hacked programs or games. Cybercriminals who distribute this ransomware are extremely clever, and aim to keep in touch with contemporary trends. New games releases, new popular movies – Yoqs developers make whatever to get their victims on that. Some of the most popular techniques these criminals utilize is one-day websites with torrent downloading links. Nonetheless, using the current things is not the only tactic these crooks use. Ways that have already turned into standard, such as e-mail spamming, are likewise common for STOP/Djvu ransomware distribution.

Malicious email spam

The example of email spamming that may lead to Yoqs ransomware injection

Preventing this ransomware does not require a lot of initiative. Adhering to the standard principles of PC hygiene will substantially reduce all risks. Remember that launching all documents you get on email is not a good idea. Even worse case is to enable macros in Microsoft Office files. But it is better to avoid the malware attack at the moment when you have only opened the e-mail message. Checking the sender’s address can point out a lot about what you can expect, and also when you see the thing like “support@amazon.com”– it is likely a genuine e-mail. On the other hand, stuff that tries to resemble Amazon or FedEx shipping alert, but uses the e-mail address of “amazonspurrot1363@gmail.com”– need to make you get on the alarm. Above, you can see the example of such a message.

Outlaw sources of different digital things need some extra explanation. Violating copyright policy already exposes you to the risk of being fined. Nevertheless, utilizing torrent trackers or third-party sites to download “free” programs likewise exposes you to a wide range of malware. Nobody can control undisclosed people that start the torrent seeding or release the hacked program version on the site with pirated software.
