What is .aira File Extension ransomware? And how does it implement its attack?

.aira File Extension ransomware is a recently discovered file-encoding threat aiming to lock files in exchange for a ransom payment. According to researchers, this new crypto-malware might be related to AiraCrop ransomware which was released way back in 2016.

Once this ransomware has managed to infiltrate the system, it will begin to drop additional malicious files to help it implement its attack. These malicious files may be dropped into several Windows folders. After that, .aira File Extension ransomware may start to create mutes, copy itself on multiple locations and may also create various types of malicious programs in the system. In addition, it also modifies Windows Registry so it can run on every system boot and after it has messed with the Registry, it begins to scan the computer looking for files to encrypt. This ransomware may target the following file formats:

.txt, .doc, .docx, .xls, .xlsx, .pdf, .pps, .ppt, .pptx, .odt, .gif, .jpg, .png, .db, .csv, .sql, .mdb.sln.php, .asp, .aspx, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .mp3, .mp4, .avi, .mov, .mpg, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf, .tax2013, .tax2014, .tax2015, .box, .ncf, .nsf, .ntf, .lwp

.aira File Extension ransomware uses both AES and RSA ciphers in locking the targeted files. It then appends the .aira extension on each one of them to mark the files it has encrypted. After that, a ransom note is delivered in a file named “How to decrypt your files.txt” that contains the message below:

“Encrypted Files!

All your files are encrypted. Using encryption AES256-bit and RSA-2048-bit.

Making it impossible to recover the files without the correct private key.
