Understand it
Ransomware can make files unusable and demand money. Some attackers also steal information and threaten to publish it. Paying does not guarantee that files will return or stolen copies will be deleted.
If files suddenly become unreadable or a ransom note appears, stop normal use and disconnect the affected device from networks where safe. At work, contact the response team immediately and follow its instructions. Get trusted help before reconnecting or restoring.
Under the hood
Encryption, deletion of recovery copies and data theft are separate behaviors. Backups can restore availability but cannot undo disclosure. Restoring into a still-compromised environment risks another incident.
Practitioner perspective
Coordinate containment, evidence preservation, legal obligations and recovery decisions. Validate clean recovery points and close the entry route before restoring. Track dependencies and credential compromise; do not equate a decrypted endpoint with eradication.

Compromise
Malicious software gains access.
Read every step without animation
Connected copies
- Compromise. Malicious software gains access.
- Files altered. Reachable documents become unusable.
- Backup reached. Writable connected copies may also be damaged.
Copy separation affects the recovery options.
Prepared recovery
- Contain. Stop the affected device communicating.
- Assess. Trusted responders investigate the entry and scope.
- Restore safely. Recover checked copies into a cleaned environment.
Recovery includes removing the cause, not just restoring files.
What could go wrong
A compromised device encrypts reachable files, including an always-connected writable copy.
What you can do
- Keep tested, separated backups and supported software.
- Preserve the note and relevant details for trusted responders without contacting the attacker yourself.
Common mistakes
- A backup does not undo stolen-data exposure.
- Payment is not a guaranteed recovery method.
