Locky
Locky is ransomware malware released in 2016. It is delivered by email (that is allegedly an invoice requiring payment) with an attached Microsoft Word document that contains malicious macros. When the user opens the document, it appears to be full of gibberish, and includes the phrase "Enable macro if data encoding is incorrect," a social engineering technique. If the user does enable macros, they save and run a binary file that downloads the ''actual'' encryption Trojan, which will encrypt all files that match particular extensions. Filenames are converted to a unique 16 letter and number combination. Initially, only the .locky file extension was used for these encrypted files. Subsequently, other file extensions have been used, including .zepto, .odin, .aesir, .thor, and .zzzzz. After encryption, a message (displayed on the user's desktop) instructs them to download the Tor browser and visit a specific criminal-operated Web site for further information. The website contains i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Necurs Botnet
The Necurs botnet is a distributor of many pieces of malware, most notably Locky. Reports Around June 1, 2016, the botnet went offline, perhaps due to a glitch in the command and control server running Necurs. However, three weeks later, Jon French from AppRiver discovered a spike in spam emails, signifying either a temporary spike in the botnet's activity or return to its normal pre-June 1 state. In a 2020 report, it was noted to have particularly targeted India, Southeast Asia, Turkey and Mexico.

Ransomware
Ransomware is a type of malware from cryptovirology that threatens to publish the victim's personal data or permanently block access to it unless a ransom is paid off. While some simple ransomware may lock the system without damaging any files, more advanced malware uses a technique called cryptoviral extortion. It encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. In a properly implemented cryptoviral extortion attack, recovering the files without the decryption key is an intractable problem – and difficult to trace digital currencies such as paysafecard or Bitcoin and other cryptocurrencies are used for the ransoms, making tracing and prosecuting the perpetrators difficult. Ransomware attacks are typically carried out using a Trojan disguised as a legitimate file that the user is tricked into downloading or opening when it arrives as an email attachment. However, one high-profile example, the WannaCry worm, traveled automat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cybercriminal
A cybercrime is a crime that involves a computer or a computer network.Moore, R. (2005) "Cyber crime: Investigating High-Technology Computer Crime," Cleveland, Mississippi: Anderson Publishing. The computer may have been used in committing the crime, or it may be the target. Cybercrime may harm someone's security or finances. There are many privacy concerns surrounding cybercrime when confidential information is intercepted or disclosed, lawfully or otherwise. Internationally, both governmental and non-state actors engage in cybercrimes, including espionage, financial theft, and other cross-border crimes. Cybercrimes crossing international borders and involving the actions of at least one nation-state are sometimes referred to as cyberwarfare. Warren Buffett describes cybercrime as the "number one problem with mankind" and said that cybercrime "poses real risks to humanity." A 2014 report sponsored by McAfee estimated that cybercrime resulted in $445 billion in annual damage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digitally Signed
A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents. A valid digital signature, where the prerequisites are satisfied, gives a recipient very high confidence that the message was created by a known sender (authenticity), and that the message was not altered in transit ( integrity). Digital signatures are a standard element of most cryptographic protocol suites, and are commonly used for software distribution, financial transactions, contract management software, and in other cases where it is important to detect forgery or tampering. Digital signatures are often used to implement electronic signatures, which includes any electronic data that carries the intent of a signature, but not all electronic signatures use digital signatures.

Domain Generation Algorithm
Domain generation algorithms (DGA) are algorithms seen in various families of malware that are used to periodically generate a large number of domain names that can be used as rendezvous points with their command and control servers. The large number of potential rendezvous points makes it difficult for law enforcement to effectively shut down botnets, since infected computers will attempt to contact some of these domain names every day to receive updates or commands. The use of public-key cryptography in malware code makes it unfeasible for law enforcement and other actors to mimic commands from the malware controllers as some worms will automatically reject any updates not signed by the malware controllers. For example, an infected computer could create thousands of domain names such as: ''www..com'' and would attempt to contact a portion of these with the purpose of receiving an update or commands. Embedding the DGA instead of a list of previously-generated (by the command and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zombie (computer Science)
In computing, a zombie is a computer connected to the Internet that has been compromised by a hacker via a computer virus, computer worm, or trojan horse program and can be used to perform malicious tasks under the remote direction of the hacker. Zombie computers often coordinate together in a botnet controlled by the hacker, and are used for activities such as spreading e-mail spam and launching distributed denial-of-service attacks (DDoS attacks) against web servers. Most victims are unaware that their computers have become zombies. The concept is similar to the zombie of Haitian Voodoo folklore, which refers to a corpse resurrected by a sorcerer via magic and enslaved to the sorcerer's commands, having no free will of its own. A coordinated DDoS attack by multiple botnet machines also resembles a "zombie horde attack", as depicted in fictional zombie films. Advertising Zombie computers have been used extensively to send e-mail spam; as of 2005, an estimated 50–80 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
