CryptolockerĬryptolocker was released in 2017, and affected over 500,000 computers. It is primarily distributed by exploit kits or phishing-attackers send emails that encourage the user to open a Microsoft Office Word or Excel file with malicious macros, or a ZIP file that installs the malware upon extraction. Locky is able to encrypt 160 file types, primarily files used by designers, engineers and testers. When it successfully encrypts files on the machine, it displays a ransom note on the desktop wallpaper. Cerber runs silently while it is encrypting files, and may try to prevent antivirus and Windows security features from running, to prevent users from restoring the system. CerberĬerber is ransomware-as-a-service (RaaS), and is available for use by cybercriminals, who carry out attacks and spread their loot with the malware developer. In 2017 WannaCry spread rapidly across 150 countries, affecting 230,000 computers and causing an estimated $4 billion in damages. It is not obfuscated and relatively easy to detect and remove. WannaCry is packaged as a dropper, a self-contained program that extracts the encryption/decryption application, files containing encryption keys, and the Tor communication program. WannaCry is an entrypting ransomware that exploits a vulnerability in the Windows SMB protocol, and has a self-propagation mechanism that lets it infect other machines. Below we list a few malware examples that made a global impact and caused widespread damage. There are thousands of strains of ransomware malware. This type of attack takes advantage of human, system, network, and software vulnerabilities to infect the victim’s device-which can be a computer, printer, smartphone, wearable, point-of-sale (POS) terminal, or other endpoint. Ransomware is a type of malware attack in which the attacker locks and encrypts the victim’s data, important files and then demands a payment to unlock and decrypt the data.
