At Black Hat, every new data source is a trade-off.

More telemetry means better visibility – but also more data for threat hunters to sift through.

Recently, Splunk Attack Analyzer (SAA) superseded Secure Malware Analytics (SMA) as the official malware threat analysis platform at Black Hat. 

With SMA, we had a simple and effective pattern: 

  • Submissions exceeding a score threshold
  • Automatically surfaced to the Threat Hunters’ incident queue on Cisco XDR

It worked well. So naturally, we wanted the same outcome with SAA.

SAA provides granular data across multiple sourcetypes, allowing for significant flexibility in how information is presented. By mapping these data streams together, we tailored our reporting to deliver a comprehensive, cohesive view of our threat landscape.

This is where David and Lily stepped in. They built a query that:

  1. Extracts submission metadata (URL, Job ID, engines used)
  2. Uses the Job ID to retrieve high-scoring results (≥85)
  3. Joins and reshapes both datasets into a single, usable structure

This was a transformative shift. By tailoring our configuration to meet our specific requirements, we unlocked a new level of visibility. This approach delivered the deep, actionable insights necessary to optimize our workflow.

With the query ready, the focus shifted to automation.

Instead of starting from scratch, we reused existing ingestion components and adapted them for this data structure.

Then came an important decision: Focus on what matters for detection of threats at Black Hat. 

SAA can accept any file format and URLs for analysis which means we saw many protocols being used, including:

  • HTTP 
  • FTP 
  • POP3/SMTP

But only HTTP had meaningful volume and relevance for the event.

So, we cut the rest. POP3/SMTP would get a chance next time around.

This was precision – prioritizing impact over completeness.

A file submitted via HTTP doesn’t exist in isolation – it has network context. So, we enriched each submission with:

  • Related traffic telemetry
  • Directionality
  • Action context (allowed vs blocked)

This turned isolated results into something threat hunters could actually investigate.

At this stage, we hit familiar challenges: 

  • Timestamp normalization (epoch → RFC3339)
  • Action context extraction (allowed vs blocked)
  • Traffic directionality

All necessary for proper ingestion into XDR.

One issue nearly derailed the correlation logic. Traffic originating from internal zones was routed through zScaler, resulting in:

  • Shared destination IPs
  • Multiple unrelated events bundled together

This could create false correlations – exactly the noise we were trying to avoid.

The fix? A targeted exception to filter it out.

Highly customized – but effective.

The workflow produced a new detection stream in Cisco XDR – powered by SAA submissions, enriched with network context.

At first glance, some alerts looked critical based on their attributes of: 

  • High scores
  • Multiple internal systems involved
  • Suspicious JavaScript obfuscation behaviour

But investigation told a different story. 

A legitimate Twitter embed. Flagged by heuristics. 

False positive. And that’s the point. 

With proper context and analysis from Attack Storyboard, the team quickly validated and dismissed it.

And that’s the real win. This workflow wasn’t about adding another data source. 

It was about:

  • Surfacing high-risk submissions automatically
  • Providing network context for faster triage
  • Helping threat hunters dismiss noise faster

This workflow is far from perfect. It will evolve, just like everything else we build at Black Hat. 

“In the end, the best detection isn’t the highest scored one – it’s the one you can act on.”
