For example, they may threaten the victim with criminal prosecution for alleged illegal acts taking place on the computer if they do not pay a “fine.” More advanced ransomware attacks deploy encryption at the disk or file-level, rendering file recovery impossible without paying the ransom.Ĭlassic ransomware attacks often invoke coercive images of logos of law enforcement agencies to scare victims into paying the ransom.
Typically victims pay the ransom in cryptocurrencies such as Bitcoin to restore access to files or prevent their public release. Ransomware is a kind of malware attack characterized by taking and keeping control of a device and its locally stored data for a ransom. Ransomware allows hackers to exert an enormous amount of pressure on victims without much technical prowess in many cases, which is why ransomware attacks are on the rise. To get it, however, the victim must pay the attacker according to the ransom instructions, often in Bitcoin.
Users will need the corresponding decryption key to unlock encrypted files. Most often, the victim introduces the ransomware to their own device by clicking an innocuous but malicious link, and once infected, the ransomware immediately begins to identify and encrypt target files, potentially spread or traverse the network to widen the scope, and ultimately results in the perpetrator demanding a ransom. These attacks are often the result of a multi-vector engagement such as social engineering schemes, watering hole attacks, carefully targeted phishing emails, taking control of hosts via the Remote Desktop Protocol, malvertising networks, and unpatched software vulnerabilities.Ī ransomware attack can target both individual users and businesses. Ransomware attack victims can attempt to reset the device or remove the malware at the risk of losing their data, or simply pay the ransom-although that last option is neither recommended by authorities nor affordable for many victims.
