Closing the Timing Gap: Defensive Temporal Observability

Lately I’ve been thinking about time.

Uptime, pulse checks, execution time, response time. We’ve always treated these as health metrics. They tell us whether a system is alive, responsive, and performing as expected. But what if they’re also security metrics?

That idea isn’t entirely new. At the network layer, covert timing channels, beaconing detection, and behavioral baselining have shown us for decades that the intervals between events matter. Attackers have long understood that rhythm carries information. More recently, researchers have demonstrated timing side-channel attacks against LLMs, using cache latency to infer private prompts and token cadence to fingerprint model outputs.

What I find interesting is the imbalance. Most of the research asks, β€œHow can timing be exploited?” Very little asks, β€œHow can timing help us defend?”

A 2026 systematic survey of LLM-agent security identifies temporal anomaly detection infrastructure as an open research gap, noting that current agent deployment frameworks don’t even support the behavioral baselines such an approach would require. Even then, the discussion largely focuses on session-level behavior. The rhythm within a single execution, the space between observable events, remains largely unexplored.

Maybe time isn’t just metadata, maybe it’s another dimension of observability that we’ve been overlooking.

Time tells you duration and speed. But read carefully, it also reveals location, choke points, and absences, the things that didn’t happen when they should have.

I’ve started exploring this in my own observability work, measuring behavioral changes & entropy across inter-arrival intervals and treating rhythm as signal rather than noise to smooth away.

Curious to know who else is working on the defensive side of temporal behavior, especially for agentic systems or any thoughts or opinions on this topic.

Can AI-generated adversaries break TTP-based attribution? (arXiv 2026)

Cyber Threat Intelligence (CTI) has traditionally attributed attacks through Tactics, Techniques and Procedures (TTPs).

In this paper we evaluate whether that assumption still holds when AI agents are explicitly configured to emulate known threat groups.

We configured AI agents to reproduce the behavior of APT28, APT29, APT41, APT44 and Lazarus inside enterprise and military cyber ranges.

Our results suggest that sufficiently capable AI agents can reproduce TTP patterns closely enough to make attribution based solely on behavioral evidence significantly more difficult.

We'd be interested in feedback from practitioners working on CTI, attribution or adversary emulation.

Towards CSI: What's the best harness? (arXiv 2026)

We studied a question that receives surprisingly little attention:

Does the agent harness matter as much as the underlying LLM?

We benchmarked five different cybersecurity scaffolds while keeping the model fixed (alias2-mini) across all 33 CyBench challenges.

Key findings:

  • No single scaffold performs best across every challenge.
  • Combining heterogeneous scaffolds consistently improves coverage.
  • A shared blackboard architecture solves 19/33 challenges (57.6%), outperforming every individual harness while reducing execution time.

Paper: https://arxiv.org/pdf/2605.28334

Happy to answer technical questions or discuss the benchmarking methodology.
