22btc ransomware is a computer infection that demands to purchase a decryption tool after it encodes all personal data on a contaminated computer. The file-locker also renames all files by appending a unique user ID, criminals’ email address, and .22btc extension to all original filenames. If you had a file named a.pdf, it would now appear as a.pdf.id-XXXXXXXX.[22btc@tuta.io].22btc.
