![]() ![]() There were 181.5 million ransomware attacks in the first six months of 2018. Starting as early as 1989 with the first documented ransomware known as the AIDS trojan, the use of ransomware scams has grown internationally. However, one high-profile example, the WannaCry worm, traveled automatically between computers without user interaction. Ransomware attacks are typically carried out using a Trojan disguised as a legitimate file that the user is tricked into downloading or opening when it arrives as an email attachment. In a properly implemented cryptoviral extortion attack, recovering the files without the decryption key is an intractable problem, and difficult to trace digital currencies such as paysafecard or Bitcoin and other cryptocurrencies are used for the ransoms, making tracing and prosecuting the perpetrators difficult. It encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. While some simple ransomware may lock the system without damaging any files, more advanced malware uses a technique called cryptoviral extortion. Ransomware is a type of cryptovirological malware that threatens to publish the victim's personal data or permanently block access to it unless a ransom is paid.
