Threat actors are increasingly shifting to languages like Go, Rust, Nim, and Dlang that can better circumvent security protections, evade analysis, and hamper reverse engineering efforts. Language like Rust are more secure as they offer guarantees like memory-safe programming, but they can also be a double-edged sword when malware engineers abuse the same features designed to offer increased safeguards to their advantage. Older malware developed using C++ and C# are being actively retooled with droppers and loaders written in uncommon alternatives to evade detection.
