MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is an Excel spreadsheet containing financial data, which is a common lure for phishing attacks. It includes an external hyperlink to a financial institution's domain, potentially directing users to a phishing site. The presence of hidden sheets and external data links suggests an attempt to conceal malicious activity or facilitate data exfiltration.

    External workbook reference in xl/externalLinks/_rels/externalLink8.xml.rels: file:///R:\GAS 2002\ANALISIACQUISTI2002.xls — a UNC/file path; opening the workbook and updating links could leak NetNTLM credentials to the host
  • External hyperlinks (1) low OOXML_EXTERNAL_HYPERLINKS
    Document contains 1 external hyperlink — clickable URLs are stored as external relationships. First target: mailto:matthew.lofting@jpmorgan.com
  • Hidden worksheet (hidden) low OOXML_HIDDEN_SHEET
    Excel workbook contains 2 hidden sheet(s) — hidden sheets are commonly used to conceal macro code, staging data, or intermediate payload construction
