<![CDATA[Credential phishing against browser-authenticated accounts can produce fragmented digital traces across browser storage, phishing infrastructure, network traffic, and account activity records. This study aims to reconstruct a Discord Web account takeover caused by credential phishing through multi-source forensic correlation. Evidence was obtained from Chrome browser artifacts, phishing server logs, Wireshark network captures, and documentation of attacker-side account activity within a controlled experimental scenario. The forensic analysis recovered 10 of 12 expected artifacts, resulting in an Artifact Recovery Rate (ARR) of 83.3%, while 4 of 6 incident stages were supported by at least two evidence items or source layers, producing an Evidence Corroboration Score (ECS) of 66.7%. The reconstructed timeline covers six stages of the incident, from the delivery of a phishing link to the confirmation of account access. The study introduces ARR and ECS as quantitative measures for evaluating artifact recovery and cross-source evidence corroboration. The findings further demonstrate that browser artifacts alone are insufficient to establish a complete account takeover sequence, and that correlation among browser, server, network, and account activity evidence is necessary to construct a coherent and verifiable forensic timeline. These results provide a practical basis for incident responders and forensic examiners to correlate heterogeneous evidence sources when investigating browser-mediated credential phishing.]]>
