Onionmail/Air—also known as AIR or Makop—belongs to the notorious Phobos-derived ransomware family. It encrypts your files, changing their extension to .AIR and appending a unique victim ID and contact email. Victims receive a ransom note demanding payment via Bitcoin. Like other Makop variants, this one proves both ruthless and financially motivated.

Detailed Analysis
How I Got Infected
Air ransomware typically spreads via phishing emails carrying malicious attachments or links, torrent downloads, and malvertising. One click is enough to launch the encryption process.
What It Does
Once executed, it scans for common file types, encrypts them with robust AES/RSA cryptography, renames them to filename.[VictimID].[email].AIR, drops a ransom note (+README-WARNING+.txt), and changes your desktop wallpaper. It may also disable shadow copies and spread additional malware.
Should You Be Worried?
Yes. It locks your files with no known free decryptor, and paying the ransom doesn’t guarantee recovery. The presence of .AIR files, ransom notes, or altered wallpapers indicates a serious ransomware infection.
