Mastering Spam a Multifaceted Approach with the Spamato Spam Filter System
DISS. ETH NO. 16839 Mastering Spam A Multifaceted Approach with the Spamato Spam Filter System A dissertation submitted to the SWISS FEDERAL INSTITUTE OF TECHNOLOGY ZURICH for the degree of Doctor of Sciences presented by KENO ALBRECHT Dipl. Inf. born June 4, 1977 citizen of Germany accepted on the recommendation of Prof. Dr. Roger Wattenhofer, examiner Prof. Dr. Gordon V. Cormack, co-examiner Prof. Dr. Christof Fetzer, co-examiner 2006 Abstract Email is undoubtedly one of the most important applications used to com- municate over the Internet. Unfortunately, the email service lacks a crucial security mechanism: It is possible to send emails to arbitrary people with- out revealing one’s own identity. Additionally, sending millions of emails costs virtually nothing. Hence over the past years, these characteristics have facilitated and even boosted the formation of a new business branch that advertises products and services via unsolicited bulk emails, better known as spam. Nowadays, spam makes up more than 50% of all emails and thus has become a major vexation of the Internet experience. Although this problem has been dealt with for a long time, only little success (measured on a global scale) has been achieved so far. Fighting spam is a cat and mouse game where spammers and anti-spammers regularly beat each other with sophisticated techniques of increasing complexity. While spammers try to bypass existing spam filters, anti-spammers seek to detect and block new spamming tricks as soon as they emerge. In this dissertation, we describe the Spamato spam filter system as a mul- tifaceted approach to help regain a spam-free inbox. -

They have done this, almost exclusively, through the building of botnets. Most people will have heard references to bots and botnets, but few people actually understand them, what they do or what the scale of the problem is. It was, for instance, reported on June 13th 2007 by the Department of Justice and FBI with reference to “Operation Bot Roast” that over 1 million victim computer IP addresses were identifi ed.1 Craig Schiller and Jim Binkley2 refer to Botnets as “arguably the biggest threat that the web community has faced.” Exactly how big that problem is, it’s diffi cult to say. -

TMRC moved into the famous old Radiation Lab structure, Building 20, a year later and began constructing its first layout. Realism mattered and club members became fanatical in the design, fabrication, and operation of their quarter-scale world. Electrical Engineering Professor Carlton Tucker was the faculty advisor who helped supply the club with sophisticated electronics. During peak membership years in the 1950s and 1960s, many TMRC members became interested in computers. Thanks to Tucker and Digital Equipment Corporation (DEC), club members began experimenting with such pioneering computers as the TX-0, PDP-1, and PDP-11. The group members became legends and were featured in Steven Levy’s paean, Hackers—Heroes of the ComputerSource: Revolution http:// . Today, the TMRC is considered by somemuseum.mit.edu/150/63 to beCollege the of Information Technology, UNITEN birthplace of hacker culture. -

CS 155 Final Exam
CS 155: Spring 2006 June 2006 CS 155 Final Exam 1. (21 points) .......................................................... Short Answer (a) (3 points) What aspect of the spam problem will DKIM prevent? Answer: Phishing email pretending to be from bank. Bounce messages to hotmail. (b) (3 points) How are secret salts used in managing a password file? What is their purpose? Answer: Add artificial entropy to user passwords. Host verifies password with all possible values of the secret salt. (c) (3 points) Suppose trusted computing (TCG) is implemented without extra hard- ware. That is, suppose all hardware secret keys are stored in the OS kernel instead of a TCG chip. The OS can use these keys to attest to application code running on top of it. Are such attestations trustworthy? If so, explain why. If not, describe an attack. Answer: No. Memory snapshots using a VMM can be used to extract the secret keys. (d) (3 points) What is the same-origin principle? Say briefly how this policy is or is not applied to (i) cookies, (ii) visited links, and (iii) frames. Answer: A web site should only have access to parts of the browser state set by the web site. Only cookies set by a web site are visible to the site. Unfortunately, history entries are visible to all sites. (e) (3 points) What is the “confused deputy” problem? How does Java stack inspection help reduce this general problem? Answer: Trusted sub system (e.g. font loader) accesses a restricted object due to a request from an untrusted sub system. (f) (3 points) What is the principle of least privilege? Why is it important? Answer: Only grant a section of code the privileges it needs to do its job.
