#Forms to go malware how toOnce the encryption is finished, DearCry will show a ransom message instructing users to send an email to the ransomware operators in order to learn how to decrypt their files. The DearCry ransomware encrypts certain types of files. DearCry is a new ransomware variant designed to take advantage of four recently disclosed vulnerabilities in Microsoft Exchange In March 2021, Microsoft released patches for four vulnerabilities within Microsoft Exchange servers. This piece of ransomware was developed to encrypt large organizations rapidly as a way of preventing its detection quickly by security appliances and IT/SOC teams. LockBit is a data encryption malware in operation since September 2019 and a recent Ransomware-as-a-Service (RaaS). This means that, in addition to demanding a ransom to decrypt data, attackers might threaten to release the stolen data if a second payment is not made. They are using the Double Extortion technique- to steal data from businesses while also encrypting the files. While REvil began as a traditional ransomware variant, it has evolved over time. REvil is known to have demanded $800,000 ransom payments. It has competed with Ryuk over the last several years for the title of the most expensive ransomware variant. The ransomware group, which has been operated by the Russian-speaking REvil group since 2019, has been responsible for many big breaches such as ‘ Kaseya‘ and ‘JBS’ REvil is one of the most well-known ransomware families on the net. The REvil group (also known as Sodinokibi ) is another ransomware variant that targets large organizations. Some Maze affiliates have transitioned to using the Egregor ransomware, and the Egregor, Maze, and Sekhmet variants are believed to have a common source. However, this does not mean that the threat of ransomware has been reduced. The group behind the Maze ransomware has officially ended its operations. The potential for an expensive data breach was used as additional incentive to pay up. If the ransom demands were not met, this data would be publicly exposed or sold to the highest bidder. When targets started refusing to pay ransoms, Maze began collecting sensitive data from victims’ computers before encrypting it. The Maze ransomware is famous for being the first ransomware variant to combine file encryption and data theft. As a result, the cybercriminals behind Ryuk primarily focus on enterprises that have the resources necessary to meet their demands. Ryuk demands ransoms that average over $1 million. Ryuk is well-known as one of the most expensive types of ransomware in existence. Once a system is infected, Ryuk encrypts certain types of files (avoiding those crucial to a computer’s operation), then presents a ransom demand. It is commonly delivered via spear phishing emails or by using compromised user credentials to log into enterprise systems using the Remote Desktop Protocol (RDP). Ryuk is an example of a very targeted ransomware variant. However, some ransomware groups have been more prolific and successful than others, making them stand out from the crowd. Dozens of ransomware variants exist, each with its own unique characteristics.
