Encryption: Right after attaining entry to the program, the ransomware commences encrypting significant files. Just about every file is remodeled into an unreadable format using complex encryption algorithms. After the encryption system is complete, the victim can no longer access their info unless they may have the decryption critical.

Ransom Demand: Soon after encrypting the files, the attacker will Show a ransom note, normally demanding copyright as payment. The note ordinarily includes Guidance regarding how to spend the ransom and a warning that the data files will be completely deleted or leaked In the event the ransom isn't paid out.

Payment and Restoration (if applicable): In some instances, victims spend the ransom in hopes of acquiring the decryption critical.
