Screen lockers: These programs are designed to lock the victim out of their computer, preventing them from accessing any files or data. These attacks are often disguised as an antivirus solution demanding payment to remove the nonexistent malware. Scareware: This common type of ransomware deceives users by displaying a fake warning message claiming malware has been detected on the victim's computer.The growing prevalence of ransomware has brought about increasingly complex ransomware attacks. The Guardian wrote about a situation where new ransomware victims were asked to have two other users install the link and pay a ransom to decrypt their files. Social engineering attackers have become more innovative over time. This attack infected labs, pharmacies and emergency rooms, highlighting the potential damage and risks of ransomware. Ransomware has attacked organizations in nearly every vertical, with one of the most famous viruses being the attacks on Presbyterian Memorial Hospital. Beyond Bitcoin, there are other popular cryptocurrencies that attackers prompt victims to use, such as Ethereum, Litecoin, and Ripple. Cryptocurrency is a digital currency that uses encryption techniques to verify and secure transactions and control the creation of new units. Ransomware attacks began to soar in popularity with the growth of cryptocurrencies, such as Bitcoin. For example, the notorious mobile ransomware Fusob requires victims to pay using Apple iTunes gift cards instead of standard currencies, like dollars. The malware then prompted the victim to send asymmetric ciphertext to the attacker to decipher and return the decryption key-for a fee.Īttackers have grown creative over the years by requiring payments that are nearly impossible to trace, which helps cybercriminals remain anonymous. Their virus contained the attacker’s public key and encrypted the victim’s files. Young and Yung presented the first cryptovirology attack at the 1996 IEEE Security and Privacy Conference. In 1996, Columbia University's Moti Yung and Adam Young introduced ransomware known as “cryptoviral extortion.” This idea, born in academia, illustrated the progression, strength, and creation of modern cryptographic tools. Payments for that attack were mailed to Panama, at which point a decryption key was sent back to the user. Ransomware can be traced back to 1989 when the “AIDS virus” was used to extort funds from ransomware recipients.
