Malware Hiding via Stack Strings Reverse Engineers Seek New Tools

Malware Hiding via Stack Strings Reverse Engineers Seek New Tools
CyberSIXT Evidence Panel Source marked as original reporting

XAVIER Mertens discusses malware obfuscation techniques, specifically focusing on stack strings in high-level programming. He highlights how these strings are dynamically constructed at runtime instead of being stored as literals, making them harder to detect using conventional tools. The article provides practical examples using assembly and C code to illustrate how stack strings are implemented and observed.

Mertens also notes the importance of reverse engineering in identifying these techniques and introduces tools to assist in the detection of obfuscated code.
