Over the past year, large language models (LLMs) have shifted from research curiosities to practical tools for offensive security.
Recent experiments show state-of-the-art models can speed up analysis, extract detection logic, and generate actionable evasion techniques for endpoint detection and response (EDR) products.
That shift matters, defenders can no longer assume local rules and signatures remain private or robust against automated scrutiny.
Researchers built a minimal but effective harness: a looped LLM agent with access to local program files and a disassembler backend (Binary Ninja).
The agent iterates over program binaries and host data, writing findings to simple markdown state files. By restarting the agent repeatedly and having it read prior outputs, the setup overcomes single-run context limits and converges on deeper leads.
No complex multi-agent orchestration was necessary just an LLM, a disassembly API, and persistent workspace files.

A major advantage of this approach is reproducibility. After extraction, rules and models are validated by running test inputs that should trigger detections.
In multiple cases, researchers appended benign markers to a PE or ran a specific reg save command and observed the extracted rule fire as expected.
That closes the loop from automated extraction to verified evasion guidance. Rapid disclosure risk, The same techniques that help red teams will accelerate public leaks of endpoint rule corpora, keys, and model behavior. EDR vendors and customers face the likelihood of rule dumps and scripted evasions circulating more quickly than before.

Local artifacts are a weak link, Shipping static rules, cached models, or embedded secrets to endpoints creates an offline attack surface. Even modest encryption or obfuscation fails when extraction logic and keys are recoverable from binaries.
Detection needs to be layered, On-host detection remains valuable but is no longer sufficient as a standalone control. Telemetry aggregation, backend correlation, network controls, and preventive measures reduce reliance on any single product’s local rules.
Specterops said, LLM-driven reverse engineering is not hypothetical it’s accelerating how quickly local EDR logic can be exposed and exploited.
That requires vendors and defenders to rethink which parts of detection live on endpoints, harden local artifacts, and rely more on layered telemetry and prevention.
At the same time, this capability gives red teams faster, verifiable ways to assess coverage a reminder that improving security often begins with realistic, up-to-date testing.
