  • 1. The State of Surveillance Christopher Soghoian Center for Cybersecurity Research Indiana University
  • 2. The state of surveillance (law enforcement)
  • 3. Wiretaps in the US • Real-time interception of communications content. • Includes – Voice communications – Text messages / IM – Network traffic (think: tcpdump) • To get one, law enforcement must get a “super warrant”: probable cause +
  • 4. The use of real-time, content intercepts (“wiretaps”) in the US continues to grow each year
  • 5. 0 500 1000 1500 2000 2500 '87 '88 '89 '90 '91 '92 '93 '94 '95 '96 '97 '98 '99 '00 '01 '02 '03 '04 '05 '06 '07 '08 '09 Intercept orders granted between 1987 and 2009 Total intercepts authorized Federal intercepts authorized
  • 6. Drugs are bad (If you value your privacy)
  • 7. 0 500 1000 1500 2000 2500 '99 '00 '01 '02 '03 '04 '05 '06 '07 '08 '09 Major offense specified in intercept order: Narcotics vs all other crimes Narcotics All other crimes
  • 8. If you are going to break the law, and don’t want to be wiretapped, stick with something safer…
  • 9. Like murder, bribery, or extortion
  • 10. Major offense specified in intercept orders (2009) Arson, explosives, and weapons 18 Bribery 2 Extortion (includes usury and loan-sharking) 3 Gambling 35 Homicide and assault 82 Larceny and theft 35 Narcotics 2,046 Robbery and burglary 9 Racketeering 61 Other or unspecified 85 Total 2376
  • 11. Phone surveillance increases each year, while other forms all decline (due to more intercepts by states, not the federal government)
  • 12. 0 500 1000 1500 2000 2500 '97 '98 '99 '00 '01 '02 '03 '04 '05 '06 '07 '08 '09 Types of intercept orders (1997 - 2009) Total Phone Intercept Orders Federal Phone Intercept Orders Total Electronic Intercept Orders Federal Electronic Intercept Orders Total Combined Intercept Orders Federal Combined Intercept Orders
  • 13. In 2009, 95% of all intercept orders were for a portable device
  • 14. 0 500 1000 1500 2000 2500 '00 '01 '02 '03 '04 '05 '06 '07 '08 '09 Location of authorized intercept orders (2000 - 2009) Personal residence Business Portable device
  • 15. Electronic intercept orders used to be significant in number…..
  • 16. 0 100 200 300 400 500 600 700 800 '97 '98 '99 '00 '01 '02 '03 '04 '05 '06 '07 '08 '09 Electronic and Combined Intercept Orders (1997 - 2009) Total Electronic Intercept Orders Federal Electronic Intercept Orders Total Combined Intercept Orders Federal Combined Intercept Orders
  • 17. But have plunged over the past few years….
  • 18. To less than 5 per year.
  • 19. 0 5 10 15 20 25 30 35 40 '04 '05 '06 '07 '08 '09 Electronic Intercept Orders (2004 - 2009) Total Electronic Intercept Orders Federal Electronic Intercept Orders
  • 20. What happened?
  • 21. Network Wiretaps? • Law enforcement agencies are simply not performing real-time data network intercepts of communications content. • These stats do not cover FISA / intel agencies, who almost certainly are. • Law enforcement are instead relying on access to stored communications (cheaper, easier, etc). • Why tap your ISP in real-time when your email provider will readily give up the files later?
