Talk Title: Spam Analytics: Exploring the

Technical and Economic Factors in Bulk Email Scams

Talk Abstract:

Today, the large-scale compromise of Internet hosts serves as a platfo

for supporting a range of criminal activity in the so-called Intern

underground economy. By far the best known example of this activity
unsolicited bulk email (spam), which has become the de facto deli

mechanism for a range of criminal endeavors, including phishing

, securities
manipulation, identity theft, and malware distribution.

The "conversion rate" of spam -- the probability t

hat an unsolicited email
will ultimately elicit a "sale" -

- underlies the entire spam value
proposition. However, our understan

ding of this critical behavior is quite
limited, and the literature l

acks any quantitative study concerning its true
value. In this talk I

will present a methodology for measuring the
conversion rate of spam.

Using a parasitic infiltration of an existing
botnet''s infrastructure

, we analyze two spam campaigns: one designed to
propagate a malware

Trojan, the other marketing on-line pharmaceuticals. For
over 240 mil

lion spam e-mails we identify the number that are successfully

ed, the number that pass through popular anti-spam filters, the

er that elicit user visits to the advertised site, and the number of

"sales" produced.

This work is in collaboration wit

h Brandon Enright, Chris Kanich, Christian
Kreibich (ICSI), Kirill

Levchenko, Vern Paxson (ICSI/Berkeley), and Stefan
Savage. It is par

t of a larger effort within the Collaborative Center for
Internet Epid

emiology and Defenses (CCIED), a joint NSF Cybertrust Center
with UCS

D and ICSI (http://www.ccied.org).
