If you needed more any more evidence as to why your DFIR practice should evolve to a heavy focus on memory analysis, let me offer you some real impetus.
FireEye's Operation Ephemeral Hydra: IE Zero-Day Linked to DeputyDog Uses Diskless Method, posted 10 NOV 2013 is specific to an attack that "loaded the payload  directly into memory without first writing to disk."

This was timely as I’ve also seen renewed interest in my Anatomy of an XSS Attack published in the ISSA Journal more than five years ago in June 2008. Hard to believe XSS vulnerabilities still prevail but according to WhiteHat Security’s May 2013 Statistics report: 1)While no longer the most pre…
