SentinelOne Uses OpenAI Daybreak to Cut Malware Reversing Time

SentinelOne slashed the time needed to reverse‑engineer complex malware from several weeks to about eight hours by adopting OpenAI Daybreak (OpenAI). The company now inspects suspicious code and gauges behavior far faster than manual methods.

Deconstructing sophisticated malicious software usually consumes four to six weeks of senior analysts' effort. Gregor Stewart, SentinelOne’s Chief AI Officer, said the AI now produces human‑level output in roughly eight hours.

The shorter analysis window lets researchers tackle a far larger pool of suspicious files. Previously, SentinelOne had to reserve deep investigations for only the most critical or high‑profile threats.

Higher throughput also helps researchers spot common components in seemingly unrelated malware samples. Those shared elements can expose links between threat campaigns that isolated analyses might miss.

Stewart warned that automation does not eliminate the need for human oversight. As he put it, "the only thing that can’t be automated is accountability," noting that critical architectural choices still require direct human judgment.

Daybreak’s rollout broadened internal access to advanced reversing tools across SentinelOne. Instead of funneling all complex tasks to a small specialist team, a wider staff group can now conduct technical threat investigations themselves.

Faster turnaround times are meant to aid customer incident response by delivering actionable leads more quickly. OpenAI Daybreak gives defensive security teams specialized model access for software dissection and threat mapping.

The dramatic reduction in reverse-engineering turnaround likely shifts the defensive bottleneck from technical analysis to strategic triage and remediation. If defenders can routinely dissect threats in hours, threat actors will likely adapt by accelerating code mutation and employing more complex obfuscation techniques. Furthermore, democratizing reverse-engineering skills internally appears set to alter security team structures, though sustaining quality control over automated decompilation outputs will remain an operational challenge.
