Inserting Garbage Bytes Anti-Disassembly
Garbage bytes are random or meaningless data that is inserted into a program's code in order to make reverse engineering and analysis more difficult. This is an anti-disassembling technique, as the insertion of these random bytes can cause disassemblers to misinterpret the code and produce incorrect disassembly results.
The insertion of garbage bytes is usually used in conjunction with other …
Debugger Evasion Defense Evasion [Mitre]
Adversaries may employ various means to detect and avoid debuggers. Debuggers are typically used by defenders to trace and/or analyze the execution of potential malware payloads.
Debugger evasion may include changing behaviors based on the results of the checks for the presence of artifacts indicative of a debugged environment. Similar to Virtualization/Sandbox Evasion, if the adversary detects a debugger, they …
FIleless Mechanisms Process Manipulating
Fileless malware is a type of malware that is designed to reside and execute entirely in the memory of a host system, without leaving any trace on the local disk. This can make it more difficult for security tools to detect and remove the malware, as it does not leave any files on the system that can be scanned or …
MPRESS Packers
MPRESS is a free packer. It makes programs and libraries smaller, and decrease start time when the application loaded from a slow removable media or from the network.
It uses in-place decompression technique, which allows to decompress the executable without memory overhead or other drawbacks; it also protects programs against reverse engineering by non-professional hackers. Programs compressed with MPRESS run …
