  • ransomware

    A form of malware in which the attacker disables or disrupts a victim’s computer and demands payment to undo the damage. Often attackers threaten to disable the computer permanently or destroy the user’s data unless they receive payment within 24 hours. Attackers frequently demand payment in cryptocurrencies such as bitcoin to make their identities and the transactions difficult to trace.
