Option C is the best answer because the scenario involves multiple jurisdictions , privacy rights , and even diplomatic immunity , which makes strict legal compliance essential. In CHFI methodology, investigators must respect rules of evidence , search and seizure requirements , privacy laws , and the need to obtain lawful authority before accessing systems or seizing digital evidence. When a case crosses borders, coordination with legal counsel and appropriate authorities becomes even more important.

The other options are clearly improper. Waiting for the suspect to leave and then seizing the device without legal authority is not defensible. Remotely accessing the computer without authorization would violate legal and ethical standards. Secretly entering the suspect’s residence is also unlawful and would likely render any evidence inadmissible. The urgency of the case does not override legal procedure.

Therefore, the proper first move is to consult legal counsel and seek the necessary warrant or international legal authorization before proceeding. This preserves admissibility, protects the investigation, and aligns with CHFI’s focus on lawful evidence handling in complex international cybercrime cases.

Option C is the strongest answer because trail obfuscation is an anti-forensics technique intended to confuse investigators by altering, hiding, fragmenting, or manipulating evidence trails such as logs, timestamps, and event records. In this situation, the correct response is not a preventive security control like stronger passwords or two-factor authentication, but a forensic method that helps reconstruct the hidden activity. Advanced log analysis tools allow investigators to correlate events, identify inconsistencies, compare multiple evidence sources, and rebuild the sequence of attacker actions despite the obfuscation.

This aligns with CHFI’s emphasis on anti-forensics techniques and countermeasures , event correlation , timeline analysis , and the use of forensic tools to detect suspicious activity across distributed systems. Real-time traffic monitoring may help with ongoing attacks, but it does not directly solve the problem of reconstructing an already obscured historical trail. The question is about overcoming concealed evidence, and that requires careful retrospective analysis.

Therefore, the most appropriate CHFI-aligned approach is to use advanced log analysis and correlation tools to piece together the obscured trail and identify the likely breach source.

Option D is the best answer because the system has already been shut down , meaning volatile evidence is likely lost and the remaining priority is to preserve and acquire non-volatile data in the most forensically sound manner possible. CHFI v11 emphasizes data acquisition methodology , choosing the best acquisition method , preserving evidence integrity, and using controlled procedures to avoid altering the source media. In this situation, removing the hard drive and attaching it to a forensic workstation is the safest and most standard approach for acquiring a reliable disk image.

Booting the suspect computer, whether with a forensic boot disk or the normal operating system, introduces risk because any boot process can change file system metadata, logs, temporary files, or other artifacts. Using the normal OS is especially unsafe. Network-based acquisition is also not appropriate here because the machine is already isolated and powered down.

A direct forensic acquisition from the removed drive minimizes unnecessary changes to the evidence source and aligns with CHFI principles of preservation, controlled handling, and repeatable imaging . Therefore, the correct next step for non-volatile data acquisition is to remove the drive and image it from a forensic workstation.
