Experts are worried about ransomware hitting critical infrastructure
Expect ransomware to grow more aggressive in the coming years, including higher ransom payments and attempts to go beyond attacking data — by shutting down entire computer systems to utilities or factories.
The computer infections work by first targeting the victim’s data, and encrypting it. The ransomware will then threaten to delete the data, unless a payment, usually in bitcoin, is made.
Experts recommend that businesses and users frequently back up their data and also test to those backups to make sure they work. Security vendors have also published tools that can free computers from some ransomware infections.
When an attack hits, victims may be tempted to pay the hackers the ransom. But be warned that one out of four times, the hackers still declined to decrypt the victim’s data, despite receiving payment.
