Ransomware attacks are typically carried out using a Trojan, entering a system through, for example, a malicious attachment or embedded link in a Phishing email or a vulnerability in a network service. The program then runs a payload, which locks the system in some fashion, or claims to lock the system but does not (e.g., a scareware program). Payloads may display a fake warning purportedly by an entity such as a law enforcement agency, falsely claiming that the system has been used for illegal activities, contains content such as pornography and "pirated" media.
Some payloads consist simply of an application designed to lock
or restrict the system until payment is made, typically by setting the Windows Shell to itself, or even modifying the master boot record and/or partition table to prevent the operating system from booting until it is repaired. The most sophisticated payloads encrypt files, with many using strong encryption to encrypt the victim's files in such a way that only the malware author has the needed decryption key.
Payment is virtually always the goal, and the victim is coerced
into paying for the ransomware to be removed—which may or may not
actually occur—either by supplying a program that can decrypt the files,
or by sending an unlock code that undoes the payload's changes. A key
element in making ransomware work for the attacker is a convenient
payment system that is hard to trace. A range of such payment methods
have been used, including wire transfers, premium-rate text messages, pre-paid voucher services such as paysafecard, and the digital currency Bitcoin. A 2016 survey commissioned by Citrix claimed that larger businesses are holding bitcoin as contingency plans
