Ransomware is a type of malicious software (malware) designed to block access to a computer system or encrypt files until a sum of money, or “ransom,” is paid. Once a device or network is infected with ransomware, the malware typically displays a message demanding payment, often in cryptocurrency, in exchange for restoring access to the data or system. Ransomware attacks can target individuals, businesses, or organizations, and they may cause significant disruption, financial losses, or data breaches. In some cases, even after payment, there is no guarantee that the attacker will provide the decryption key or restore access, making ransomware a particularly pernicious form of cyber threat.
