An insider threat deleting sensitive data would primarily manifest as data loss, not typically as widespread file encryption coupled with original file deletion.

External attackers exfiltrating data stealthily involves unauthorized data transfer outside the network, which is distinct from the on-system encryption and deletion associated with ransomware.

A ransomware attack typically involves encrypting a victim's files to render them inaccessible and often includes deleting the original unencrypted files to prevent straightforward recovery without the attacker's decryption key.

A misconfigured backup process might cause data issues or loss, but it would not deliberately encrypt files and delete their originals in a malicious pattern characteristic of an attack.
