AAYU Virus (.aayu File) Ransomware — Remove & Decrypt Files

If you cannot open your photos, documents, or other files and see the .aayu extension on them, your PC is surely infected with Aayu ransomware. It belongs to STOP/Djvu ransomware group

Aayu ransomware ciphers personal documents found on the victim’s PC with the extension “.aayu” and after that leaves the ransom note in each folder which contains encrypted files. The instructions are put on the victim’s PC in the “readme.txt” file. Its activity is basically similar to other examples of the same ransomware family: Aabn, Aamv, Aawt.

What is Aayu Ransomware?

Aayu is file-encrypting ransomware that prevents access to your text files, Excel tables, videos and photos by encrypting them. It marks the ciphered files with the “.aayu” extension. Then Aayu ransomware adds a money 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 wallet. The AES-256 or RSA-1028 cipher it uses to encrypt the files is not decryptable with modern computers. Even quantum PCs that already exist will spend thousands of years to get the decryption key.

How dangerous is the Aayu ransomware?

When Aayu ransomware appears in your system, it will examine your system for photos, videos, and also important documents. It [ciphers all widespread file formats- .psd, .doc, .docx, .xls, .xlsx, .pdf, .jpeg, .png, et cetera. When these documents are found, the ransomware will encrypt them and also change their extension to “.aayu” to make sure that you understand what happened.

After the Aayu ransomware encrypted the files on your PC, it will drop the last “readme.txt” file on the desktop. In addition to the money transferring instructions, the victims also see the emails to contact the fraudsters – helprestoremanager@airmail.cc and manager@mailtemp.ch.

How did the Aayu ransomware get on my computer?

The Aayu ransomware spreads by posting websites to get hacked programs or games. Cybercriminals who spread this ransomware are quite clever, and aim to correspond with current trends. New games introductions, new popular films – Aayu creators make whatever to get their money on that. One of the most favored methods these burglars put to use is one-day websites with torrent downloading links. Nonetheless, using the contemporary things is not the only manner these criminals utilize. Methods that have already become classic, such as e-mail spamming, are likewise common for STOP/Djvu ransomware spreading.

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

Avoiding this ransomware does not need a lot of initiative. Using the ordinary rules of PC hygiene will noticeably minimize all dangers. Bear in mind that opening all documents you get on email is not a great idea. Even worse scenario is to allow macros in Microsoft Office documents. However, it is much better to stop the malware attack at the moment when you have only opened the e-mail message. Examining the sender’s address can say a lot about what you can anticipate, as well as when you see the thing like “support@amazon.com”– it is likely a trustworthy e-mail. At the same time, stuff that tries to look like Amazon or FedEx delivery notification, however, uses the email address of “amazonspurrot1363@gmail.com”– should make you get on the alarm. Above, you can see the illustration of such a message.

Illegal sources of various digital things need some additional explanation. Violating copyright regulation surely throws you to the danger of being fined. Nonetheless, utilizing torrent trackers or third-party sites to download “free” programs also exposes you to different malware. No one can regulate unidentified people that start the torrent seeding or publish the hacked program version on the website with pirated program.
