Handling Novel Technologies and Evidence Questions

Covers how a candidate responds when encountering unfamiliar hardware, software, devices, file systems, encryption schemes, or novel data structures and evidence types. Assess the candidate on troubleshooting fundamentals applied to unknown systems, rapid learning and research strategies, use of documentation and external resources, when and how to engage subject matter experts, and how they validate and document new techniques. Interviewers may probe for examples of unexpected findings, how the candidate iterated on investigative approaches, risk management under time pressure, and how they ensured forensic soundness and reproducibility when standard tools or processes did not apply.

You are given a pcap containing traffic of an unknown binary protocol used by a proprietary device. Implement in Python or outline an algorithm that clusters similar flows, detects consistent field boundaries (message delimiters), extracts candidate message types, and outputs representative message samples for manual analysis. Consider performance and scalability for large pcaps.

Describe a time you escalated an investigation to a subject matter expert (SME). Explain what indicators triggered escalation, how you prepared and packaged data/questions for the SME to be efficient, how you tracked the SME's findings, and how their input changed your approach.

Describe advanced anti-forensics techniques adversaries use to evade evidence collection (log tampering, timestomping, memory-only artifacts, rootkits, ephemeral cloud instances) and propose resilient detection and mitigation strategies that generalize to novel methods. Include ideas for instrumentation, baseline collection, anomaly detection, and immutable logging.

Explain chain-of-custody: what fields you record when collecting evidence (who, when, how, tools, hash values), how transfers should be logged, and practical steps to close gaps if a custody record is incomplete for a piece of evidence from an unfamiliar device.

Define 'forensic soundness' in the context of handling novel technologies and evidence. Explain the core principles you rely on (integrity, reproducibility, minimal alteration, documentation), why they matter when investigating unfamiliar hardware/software, and give two brief examples of how violating them can affect analysis or legal admissibility.
