## Summary

SentinelOne reports that OpenAI's Daybreak platform has reduced the time required to reverse-engineer sophisticated malware from four to six weeks to approximately eight hours. Gregor Stewart, SentinelOne's Chief AI Officer, states that the tool produces human-level output, allowing security researchers to investigate a larger volume of samples and identify connections between threats that were previously missed due to time constraints.

The shift enables SentinelOne to map a broader section of the malware landscape, helping defenders spot shared components across unrelated samples. Stewart notes that while AI accelerates analysis, human accountability remains essential for architectural decisions. The company is also integrating these capabilities into its development workflow, aiming to give more team members access to expert-level security insights that were previously limited to a small group of specialists.

## Key points

- Malware reverse-engineering time drops from 4-6 weeks to roughly 8 hours using OpenAI Daybreak.
- SentinelOne uses the tool to compare more samples and find connections between unrelated threats.
- Gregor Stewart says human accountability remains necessary for architectural security decisions.

## Why it matters

Accelerating malware analysis allows security teams to keep pace with evolving threats and identify broader attack patterns, shifting the advantage to defenders by democratizing expert-level cyber capabilities.
