This white paper demonstrates how ProfiShark 1G supported digital forensics and incident response when conventional host-based tools failed to detect a compromise. A suspicious system produced a strong indicator of compromise, yet rootkit scanners reported it as clean. The analyst used network-based cross-view analysis, comparing connections shown by the host with traffic independently captured beside its network interface. Netstat displayed only the analyst’s authorized SSH session, while the ProfiShark capture revealed an additional hidden SSH connection to an unfamiliar foreign address. This discrepancy confirmed that the system was compromised and allowed it to be isolated for remediation. The paper highlights ProfiShark’s portable, cross-platform, lossless capture, unbiased visibility
