Backstory brings agentic investigation to malware blast-radius analysis
Help Net Security featured the launch of Stairwell Backstory, a new agentic investigation platform designed to help security teams move beyond isolated alerts and uncover the complete scope of a malware incident.
Backstory examines the executable files that have actually appeared inside an organization, connects related malware variants, identifies impacted systems, and reconstructs how a threat moved through the environment.
For every published malicious hash, Stairwell identified an average of 2.4 additional malicious variants.
Why it matters
Traditional investigations often stop after the original alert is resolved. That can leave related variants, previously affected systems, and older malicious files undiscovered.
Backstory is designed to answer the questions that remain after the alert:
- What else is related to this malware?
- Which systems were affected?
- How long has the threat been present?
- Has the incident actually been contained?
Investigation grounded in the files themselves
Rather than relying only on alerts or published indicators, Backstory investigates against a private historical corpus of executable files collected from the customer’s environment. This allows previously seen files to be analyzed again as new malware intelligence, variants, and detection techniques emerge.
