Encrypt Files for Impact

Malware may encrypt files stored on the system to prevent user access until a ransom is paid and/or to interrupt system availability. The encryption process usually iterates over all letter drives in the system (except for CD drives) and then recursively encrypts all files with specific suffixes.

See ATT&CK: Data Encrypted for Impact and Encrypt Files (Mobile).
