A polymorphic engine (sometimes called mutation engine or mutating engine) is a software component that uses polymorphic code to alter the payload while preserving the same functionality. Polymorphic engines are used almost exclusively in malware , with the purpose of being harder for antivirus software to detect.
Polymorphic algorithms make it difficult for such software to recognize the offending code because it constantly mutates. Malicious programmers have sought to protect their encrypted code from this virus-scanning strategy by rewriting the unencrypted decryption engine (and the resulting encrypted payload) each time the virus or worm is propagated.
The Smeg Virus Construction Kit (or SMEG) is a polymorphic engine written by virus writer Chris Pile, known as The Black Baron. SMEG is an acronym for Simulated Metamorphic Encryption Generator. SMEG is an acronym for Simulated Metamorphic Encryption Generator.
Metamorphic code is used by some viruses when they are about to infect new files, and the result is that the next generation will never look like current generation. The mutated code will do exactly the same thing (under the interpretation used), but the child's binary representation will typically be completely different from the parent's.
In computer security, a drive-by download is the unintended download of software, typically malicious software. The term "drive-by download" usually refers to a download which was authorized by a user without understanding what is being downloaded, such as in the case of a Trojan horse. In other cases, the term may simply refer to a download ...
Download and execute is a type of remote shellcode that downloads and executes some form of malware on the target system. This type of shellcode does not spawn a shell, but rather instructs the machine to download a certain executable file off the network, save it to disk and execute it.
The uptick in activity was largely driven by the services sector. The services component of S&P's report showed the index registered 57 this month, up from 55 in October and the highest level in ...
Cheat Engine allows its users to share their addresses and code locations with other users of the community by making use of cheat tables. "Cheat Tables" is a file format used by Cheat Engine to store data such as cheat addresses, scripts including Lua scripts and code locations, usually carrying the file extension.ct. Using a Cheat Table is ...
