#60 Shellcode Evasion in 2025: What Still Works (and What Doesn’t) ft. Robert O’Connor

In this episode of The Hacker’s Cache, Kyser Clark sits down with Red Team Consultant Robert O’Connor to unpack the realities of shellcode evasion in 2025. They dive into how antivirus and EDR solutions actually detect malicious payloads, the rise of fileless malware, and why network-level detection is still overlooked. Robert shares his hands-on experience building custom evasion techniques, his transition from pentesting to red teaming, and how certifications like CRTO and OSED fit into the bigger picture. Whether you’re a pentester, red teamer, or just curious about modern adversary simulation, this conversation reveals what still works, what doesn’t, and where the field is heading.
