Mission Brief

Following detection of anomalous data access patterns by the client's SIEM system, conduct an open-source and behavioral intelligence assessment to support internal investigation into potential data exfiltration by a current or former employee.

Investigation Scope

Digital footprint analysis, behavioral pattern mapping, temporal correlation with known access events, open-source persona investigation.

Deliverables
  • Correlate SIEM-flagged access events with external indicators
  • Map the digital footprint of persons of interest
  • Identify potential data exfiltration channels
  • Assess motivational and behavioral indicators
Confidence LevelHigh
Initial Signals
  • Bulk data access events outside normal working hours
  • VPN connections from previously unseen geographic locations
  • Personal cloud storage domains in DNS logs during access windows
  • LinkedIn activity suggesting imminent departure to competitor

Analytical Findings

Key Conclusions
  • 01

    Person of interest accessed 47 sensitive repositories in a 72-hour window preceding their resignation notice.

  • 02

    DNS logs confirmed connections to personal cloud storage during each bulk access event.

  • 03

    Open-source investigation revealed the individual had registered a competing business entity 6 weeks prior to the access anomalies.

  • 04

    Behavioral indicators consistent with pre-planned exfiltration rather than incidental data handling.

Strategic Recommendation

Findings support initiation of formal legal proceedings. Recommend immediate credential revocation and forensic imaging of assigned devices.

LEGAL ACTION RECOMMENDED

Case Outcome

Client Impact

Client initiated legal proceedings based on the intelligence assessment. Forensic analysis of devices confirmed the exfiltration hypothesis. Settlement reached under NDA terms.
