Ransomware is a type of advanced malware attack that takes hold of a device, either locking the user out entirely or encrypting files so they cannot be used. This type of attack can gain access to your device in a variety of ways. Whether downloaded from a malicious or compromised website, delivered as an attachment from a phishing email or dropped by exploit kits onto vulnerable systems, once executed in the system ransomware will either lock the computer or encrypt predetermined files. The attacker will then make themselves known with an “official” ransom demand, as well as thorough instructions and timelines on how to make a payment to either regain access to the device or to receive the decryption key for the captive files.
