Extensions to the IODEF-Document Class for Reporting Phishing
Abstract
This document extends the Incident Object Description Exchange Format
(IODEF) defined in RFC 5070 to support the reporting of phishing
events, which is a particular type of fraud. These extensions are
flexible enough to support information gleaned from activities
throughout the entire electronic fraud cycle -- from receipt of the
phishing lure to the disablement of the collection site. Both simple
reporting and complete forensic reporting are possible, as is
consolidating multiple incidents.
