Ransomware attacks are typically carried out using a Trojan, entering a system through, for example, a malicious attachment, an embedded link in a phishing email, or a vulnerability in a network service. The program then runs a payload, which locks the system in some fashion, or claims to lock the system but does not (e.g., a scareware program).
[2] Due to public outcry about this cryptovirology attack, NIST rescinded the EC-DRBG algorithm from the NIST SP 800-90 standard. [ 3 ] Covert information leakage attacks carried out by cryptoviruses, cryptotrojans, and cryptoworms that, by definition, contain and use the public key of the attacker is a major theme in cryptovirology.
PGPCoder or GPCode is a trojan that encrypts files on the infected computer and then asks for a ransom in order to release these files, a type of behavior dubbed ransomware or cryptovirology. Trojan [ edit ]
Conti ransomware employs various stealth techniques, including the use of BazarLoader, to infiltrate its target systems. The ransomware is designed to encrypt files and render them inaccessible until a ransom is paid. It is often delivered through phishing emails, exploit kits, or compromised websites. [1]
A logic bomb is a piece of code intentionally inserted into a software system that will set off a malicious function when specified conditions are met. For example, a programmer may hide a piece of code that starts deleting files (such as a salary database trigger), should they ever be terminated from the company.
July 6: Bohmini.A is a configurable remote access tool or trojan that exploits security flaws in Adobe Flash 9.0.115 with Internet Explorer 7.0 and Firefox 2.0 under Windows XP SP2. [50] July 31: The Koobface computer worm targets users of Facebook and Myspace. New variants constantly appear. [51]
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.
Creating a unified list of computer viruses is challenging due to inconsistent naming conventions. To combat computer viruses and other malicious software, many security advisory organizations and anti-virus software developers compile and publish virus lists.
