A wiper is a type of malicious software (malware) designed specifically to delete, overwrite, or corrupt data on a computer or network. Unlike ransomware, which typically demands payment to restore access to data, wipers aim to permanently destroy information, making recovery difficult or impossible. Attackers may use wipers to sabotage organizations, disrupt operations, or erase evidence of other cybercrimes. Wiper attacks can have severe consequences, including financial loss, reputational damage, and operational downtime.
