Encryption: Just after getting access to the program, the ransomware commences encrypting important documents. Each and every file is transformed into an unreadable format utilizing complex encryption algorithms. After the encryption method is complete, the sufferer can no longer obtain their facts unless they may have the decryption crucial.

Ransom Demand: Immediately after encrypting the files, the attacker will Display screen a ransom Be aware, generally demanding copyright as payment. The note ordinarily includes Guidance regarding how to fork out the ransom along with a warning the documents might be completely deleted or leaked When the ransom just isn't paid out.

Payment and Recovery (if applicable): In some instances, victims spend the ransom in hopes of obtaining the decryption essential.
