What it is

CISA describes ransomware as malware designed to encrypt files on a device, making them unusable, after which criminals demand a ransom to decrypt them.

Who is at risk

CISA says anyone with a computer connected to the internet is at risk.

Paying is no guarantee

CISA says some victims pay to recover their files, but "there is no guarantee that they will recover their files if they do."

Precautions CISA lists

CISA says to update software and operating systems with the latest patches, and never to click links or open attachments in unsolicited emails.

Backups

CISA says to back up data regularly, keep it on a separate device, and store it offline.

This is general information, not security or technical support advice.

We do not give that advice. CISA says paying does not guarantee you get your files back.
