The Mira Ransomware is a variant of the Planetary Ransomware, which itself is based on the HC7 Ransomware. The Mira Ransomware was identified by computer security experts on April 5th, 2019. The Mira Ransomware Trojan might enter systems via corrupted Microsoft Word files, PDF files with double extensions (like 'Sample.PDF.EXE') and pirated software. The Mira Ransomware is a program that can use processes with random names and run code via the Command Line utility by Microsoft to hide its activity. The Mira Ransomware is designed to use a custom version of the Rijndael algorithm that is one of the key components of the trusted AES (Advanced Encryption Standard) cipher. The Trojan at hand enciphers data containers with the following extensions:
.3gp, .7z, .apk, .avi, .bmp, .cdr, .cer, .chm, .conf, .css, .csv, .dat, .db, .dbf, .djvu, .dbx, .docm, .doc, .epub, .docx, .fb2, .flv, .gif, .gz, .iso .ibooks, .jpeg, .jpg, .key, .mdb .md2, .mdf, .mht, .mobi .mhtm, .mkv, .mov, .mp3, .mp4, .mpg .mpeg, .pict, .pdf, .pps, .pkg, .png, .ppt .pptx, .ppsx, .psd, .rar, .rtf, .scr, .swf, .sav, .tiff, .tif, .tbl, .torrent, .txt, .vsd, .wmv, .xls, .xlsx, .xps, .xml, .ckp, .zip, .java, .py, .asm, .c, .cpp, .cs, .js, .php, .dacpac, .rbw, .rb, .mrg, .dcx, .db3, .sql, .sqlite3, .sqlite, .sqlitedb, .psd, .psp, .pdb, .dxf, .dwg, .drw, .casb, .ccp, .cal, .cmx, .cr2.
The encrypted data is saved over the original data, and the Shadow Volume snapshots made by Windows are deleted. In other words, the Mira Ransomware reads the files on your PC and overwrites saved content, as well as remove backups made by Windows. Affected files receive the '.mira' extension. For example, 'Tales of Ladybug & Cat Noir.mp4' is renamed to 'Tales of Ladybug & Cat Noir.mp4.mira.' The team behind the Mira Ransomware might offer help with decrypting your data in exchange for $500 and more. Most Ransomware actors accept payments in Bitcoin (BTC), but some accept other cryptocurrencies like Ethereum (ETH), Litecoin (LTC), Dogecoin (DOGE) and others. The Mira Ransomware team remains "orthodox" and requires payments in BTC, but first, you will need to send them an email. The Mira Ransomware Trojan is instructed to write '!!!READ_IT!!!.txt' to the users desktop and offer the following message:
'ALL YOUR DATA WAS ENCRYPTED
If you want to recover your data:
1.Send your personal ID to our emails.
2.You can send us 1 small file for test decryption.
3.After payment you will get decryption tool and opportunity to recover all your data.
To avoid file loss, do not try to rename or modify encrypted files.
