FRACTION LOADER: IN-MEMORY LOADER PROJECT

Summary from the TLDR InfoSec newsletter

Fraction Loader is an educational malware project that creates a stealthy in-memory loader capable of downloading, reassembling, and executing payload fragments without touching disk. It uses Windows APIs like VirtualAlloc and WinHTTP to handle encrypted payload chunks, parse headers for order, and reassemble them into executable memory with suitable permissions. While meant for penetration testers and security researchers to learn evasion techniques, it functions as a weaponized dropper that can bypass file-based detection and pose a threat to InfoSec professionals monitoring for in-memory attacks.
