Some Malicious PE Stats, (Thu, Aug 27th)

This report presents a large-scale statistical analysis of PE files (downloaded from MalwareBazaar, 2020-02-24 to 2026-07-08) using pefile to extract Rich Header, CLR metadata, and heuristic signatures; it summarizes counts for architectures, Rich Header presence, top linker versions and MSVC builds, and identifies likely compiler/toolchain usage (MSVC, GCC/MinGW, Delphi, Go, Rust, etc.), concluding that 32-bit malware remains prevalent and newer languages like Go and Rust are still uncommon in the dataset.
