This article discusses a proof-of-concept for sleep obfuscation on Linux using sigreturn-oriented programming (SROP). It focuses on encrypting PT_LOAD segments and the heap to enhance security. The approach aims to protect processes from certain types of attacks.

Founding is a tool designed for processing shellcode into stealthy binaries by employing various advanced obfuscation and encryption techniques. It features capabilities such as dynamic API hashing, IAT camouflage, and multiple execution methods, enabling greater evasion of detection by security software. The tool supports various payload formats and includes functionalities for creating DLLs and executables with enhanced stealth and legitimacy.

Ebyte-Go-Morpher is a Go program that obfuscates Go source code by manipulating the Abstract Syntax Tree (AST) to enhance security. It offers various obfuscation techniques, including string encryption, identifier renaming, and number obfuscation, while preserving reflection compatibility and allowing configuration of features. The tool generates obfuscated files and runtime decryption logic, streamlining the process of protecting Go code.

ByteCaster is a versatile tool for payload encryption, obfuscation, and conversion to various byte array formats using a single command. It supports three encryption algorithms, four encoding methods, and fourteen output formats, allowing users to manipulate binary files easily. Examples demonstrate its functionality with features like XOR encryption and different output formats, including C and base64 strings.
