A Scottish brewery has warned other firms to stay alert after it fell victim to a ransomware attack.
Arran Brewery said it was locked out of its own computer system after being duped into opening an email attachment which contained a virus.
According to the firm, the culprits then demanded two bitcoins, worth a total of £9,600, to restore the system.
