Summary
Detects inbound messages that attempt to deceive recipients with fake copyright claims formatted as HTML tables containing a 25px image in the first cell and a hyperlink in the second cell, where the link text references PDFs. The rule looks for an HTML table row pattern (tr[td[1]/img[@height="25px"]]/td[2]//a]) and requires the display_text to contain the string "PDF". This combination is indicative of malicious PDF delivery attempts using deceptive formatting to lure users into clicking links. The detection supports content/HTML analysis focused on image-based evasion techniques and PDF delivery schemes.
