TL;DR: Connected systems remain vulnerable to state cyber warfare because attackers can modify code, disrupt operations and exploit runtime weaknesses across military, home and critical infrastructure environments, according to Karamba Security. Deterministic runtime protection matters when network detection alone cannot stop malicious code injection or tampering.
Editorial analysis by NHI Mgmt Group, based on content published by Karamba Security: “Blog”.
Key questions
Q: Why does network monitoring miss code injection attacks?
A: Network monitoring often misses code injection because the malicious change happens inside a running process or memory space after traffic is decrypted or already allowed.
Q: How should teams protect critical systems that cannot go offline?
A: Protect systems that cannot go offline with layered controls that reduce change and limit blast radius: strict allowlisting, signed updates, segmentation, least privilege, immutable configuration, and high-availability failover.
Q: How do I detect runtime tampering in connected devices?
A: Detect runtime tampering by combining integrity monitoring, process and memory inspection, secure boot attestation, and file hash baselines on the device.
Practitioner guidance
- Implement runtime integrity enforcement Use controls that verify code and configuration at execution time, not only at deployment time, for devices that cannot be taken offline safely.
- Restrict modification paths on connected devices Limit who and what can alter firmware, logic or runtime parameters, and treat every write path as a high-risk change channel.
- Assume network detection is not enough Pair monitoring with anti-tamper and known-good state validation, because traffic inspection alone will miss subverted local execution.
Bottom line: Connected systems are exposed to a class of cyber warfare that targets runtime behaviour, not just perimeter access.

Runtime integrity is the real control boundary for connected systems. Once a device cannot be safely disconnected, network visibility becomes insufficient as the primary defensive assumption. The decisive question is whether the system can resist unauthorized modification while it remains live. That makes integrity enforcement and trusted execution the governance problem, not just incident response.
A question worth separating out:
Q: What happens when code tampering reaches operational technology?
A: When code tampering reaches operational technology, it can alter control logic, change sensor readings, disrupt physical processes, or hide unsafe states from operators. The impact is not just cyber compromise but loss of process integrity, safety margin, and reliable control. Defences centre on segmentation, signed logic, strict change control, engineering workstation protection, and monitoring that covers both IT and OT layers.
