Leak Dataset Module in SecTepe.Core: Investigate Data Exfiltration Forensically

When corporate data surfaces in a leak, every hour counts – and every statement must be robust. The new leak dataset module in SecTepe.Core turns a chaotic data dump into a structured, verifiable analysis: it shows what is actually contained, assigns the exposure, and delivers the basis for notification and response.

What Does the Dump Really Contain?

Instead of a folder with thousands of files, the handler gets a structured view of what is inside a dataset. A paginated file browser handles even folders with around 11,000 files a page at a time, without overloading the interface – important when you have to review a real dump and not a demo example.

Assign the Exposure Cleanly

The module lets handlers assign the relevant exposure to a dataset:

  • affected systems the data originates from,
  • involved third parties (service providers, partners),
  • the affected time period,
  • affected business records or datasets.

For discovered credentials and accesses, the module also generates rotation documentation – the list of what must be reset after the incident, cleanly logged.

"A Failed Search Is Not an All-Clear"

Perhaps the most important principle isn't in a feature but in the hardening: the module was intensively secured against misinterpretation. A failed search is not reported as an all-clear, and a pending assessment is not treated like a zero finding. Interim answers explicitly state what they rest on. This prevents the most dangerous false statement of all: saying "nothing found" when you simply haven't finished searching yet.

Fed by the CTI Pipeline and Interlinked With SnapScan

The module is fed by the threat intelligence pipeline of SecTepe.Core.CTI – the same machinery that ingests ransomware leaks in a GDPR-compliant way (see leak ingest). Via the /my-leaks integration, SecTepe SnapScan also accesses this exposure view, so the pentest and leak perspectives converge.

Conclusion

The leak dataset module transforms a data exfiltration from a source of panic into a workable case: visible content, assigned exposure, rotation documentation – and a built-in caution that names interim states honestly. That robustness is exactly what you need when deadlines are running and supervisory authorities are watching.
