CryptoLocker typically propagated as an attachment to a seemingly innocuous email message, which appears to have been sent by a legitimate company. [5] A ZIP file attached to an email message contains an executable file with the filename and the icon disguised as a PDF file, taking advantage of Windows' default behaviour of hiding the extension from file names to disguise the real .EXE extension.
Ransomware is a type of malware that encrypts the victim's personal data until a ransom is paid. [1] [2] [3] [4] [5] They commonly use difficult-to-trace digital ...
The WannaCry ransomware attack was a worldwide cyberattack in May 2017 by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin cryptocurrency. [4]
LockBit is a cybercriminal group proposing ransomware as a service (RaaS). Software developed by the group (also called ransomware) enables malicious actors who are willing to pay for using it to carry out attacks in two tactics where they not only encrypt the victim's data and demand payment of a ransom, but also threaten to leak it publicly if their demands are not met.
Rhysida is a ransomware group that encrypts data on victims' computer systems and threatens to make it publicly available unless a ransom is paid. [1] The group uses eponymous ransomware-as-a-service techniques, targets large organisations rather than making random attacks on individuals, and demands large sums of money to restore data.
Cryptovirology refers to the study of cryptography use in malware, such as ransomware and asymmetric backdoors. [citation needed] Traditionally, cryptography and its applications are defensive in nature, and provide privacy, authentication, and security to users. Cryptovirology employs a twist on cryptography, showing that it can also be used ...
The gang was first spotted by researchers in February 2019. It evolved as a variant of the "CryptoMix" ransomware family. Clop is an example of ransomware as a service (RaaS). Clop ransomware used a verified and digitally signed binary, which made it look like a legitimate executable file that could evade security detection. [5]
The "ransomware as a service" model is a criminal variation of the "software as a service" business model. [3] This model allows small threat attackers to gain access to sophisticated ransomware tools at lower costs, also lowering the threshold of entry into cybercrime and complicating defenses against hacking.
