Legal Issues in Mobile Security Research

299

Published on

I gave this talk at CanSecWest in 2012. Abstract:

This presentation will identify and discuss sticky legal problems raised by researching the security of mobile devices. Using American law as a jumping-off point, I'll discuss common legal issues that arise in mobile security research such as jailbreaking, reverse engineering, and interception of communications. We'll also talk about practical ways to reduce the risks of your research so that you can go about your work with less potential for legal trouble.

Transcript of "Legal Issues in Mobile Security Research"

  1. 1. Legal Issues in Mobile Security Research CanSecWest March 8, 2012 Marcia Hofmann, EFF
  2. 2. what we’ll talk about today✪  Why mobile security research presents uniquelegal considerations.✪  Some of the laws you should be aware of whenyou’re doing mobile security research.✪  Ways to reduce whatever risk your researchmight create.
  3. 3. what do I mean by “risk”? A couple distinct, separate things. (1) The likelihood of becoming an attractivetarget for a law suit or prosecution, either with or without basis.(2) The likelihood that a court might decide that you’ve run afoul of the law.
  4. 4. My goal today is not to frighten you or discourage your research.I want to help you spot potentially stickysituations so that you can call a lawyer early to help you safely navigate them.I also want to help you think proactivelyabout ways to design your research to avoid trouble.
  5. 5. This is not legal advice.If you are concerned about the legality of your research, you should speak with a lawyer about your specific situation.
  6. 6. What makes mobile security research legally interesting?
  7. 7. factors✪ Networked devices that access, store and transmit vast amounts of information, lots of which is intensely personal✪ Many different players involved in the space: manufacturers, platform providers, software developers, carriers, users✪ Embedded software (tricky © issues)
  8. 8. some legal considerations*
  9. 9. contract law
  10. 10. which contracts?The documents that set out terms purporting toregulate how people can access and use a device/ program/service.E.g., end-user license agreements, SDK licenses, terms of use, carrier contracts
  11. 11. Be sure to check whether more than one agreement might apply to your research.Also see whether other agreements/policies are incorporated be reference, and read them, too.
  12. 12. laws that might applyViolating an agreement could involve:✪  Breach of contract ✪  civil claim ✪  monetary damages, if any (compensation for loss) ✪  perhaps account terminated✪  Computer crime laws…?
  13. 13. computer intrusion laws
  14. 14. laws that might applyAccessing someone else’s computer might involve: (1)  Computer Fraud and Abuse Act 18 U.S.C. § 1030 (2) Similar state computer crime laws
  15. 15. unauthorized accessThe CFAA prohibits, among other things,“intentionally access[ing] a computer without authorization or in excess of authorization, and thereby obtain[ing] . . . information from any protected computer.”18 U.S.C. § 1030(a)(2)(C).
  16. 16. Folks have tried to make creative arguments for defining “unauthorized” to include violating agreements… United States v. Drew Facebook v. Power Ventures Sony v. Hotz
  17. 17. This is especially problematic because the CFAA is both a civil and criminal law.
  18. 18. Also, one court recently held that designing a tool to avoid IP blocking violated the CFAA. Facebook v. Power Ventures
  19. 19. copyright laws
  20. 20. laws that might applyAccessing and making copies of someone else’s copyrighted code might involve: (1)  Copyright Act (copying) 17 U.S.C. §§ 101 et seq. (2) Digital Millennium Copyright Act (accessing/enabling others to access) 17 U.S.C. § 1201
  21. 21. Copyright Act✪  Broadly prohibits infringement of copyrighted works.✪  This includes making copies of code written by others.✪  Stiff penalties (injunctions, statutory damages, criminal penalties).
  22. 22. important exception #1: fair use It’s OK to use copyrighted material for purposes such as research, news reporting,commentary, criticism, and scholarship under certain circumstances.
  23. 23. important exception #1: fair use Four-factor balancing test ✪ Purpose and character of the use ✪ Nature of the copied work ✪ Amount and substantiality used ✪ Effect on the market
  24. 24. fair use and reverse engineeringIf reverse engineering is necessary to gain accessto functional processes and ideas, intermediatecopies are fair use.Be sure that you’re legitimately in possession ofthe software, and don’t use someone else’s code inyour final product unless absolutely necessary.
  25. 25. contracts revisitedSome agreements forbid reverse engineering. Can they do that? So far, the courts say yes.
  26. 26. important exception #2: Section 117The owner of a copy of a computer program may copy or adapt it as “an essential step in the utilization of the computer program with a machine[.]”
  27. 27. Digital Millennium Copyright Act Two basic prohibitions:(1) Can’t circumvent technological measures that effectively protect or control access to copyrighted works(2) No trafficking in tools that are primarily designed, valuable or marketed for (1)
  28. 28. Digital Millennium Copyright Act Again, tough civil/criminal penalties. (injunctions, statutory damages, criminal fines, prison time)
  29. 29. protection/access measures CSS protocol encryption authentication handshakes “chain of trust” signing? code obfuscation? proprietary protocols?
  30. 30. important exceptions reverse engineering encryption research security researchpersonally identifiable information (PII)
  31. 31. reverse engineering: breakdown✪  Lawfully obtained the program, and✪  Circumvention is for the sole purpose of identifying and analyzing to achieve program- to-program interoperability, and✪  Information not previously readily available, and✪  Not infringing.
  32. 32. reverse engineering: breakdownInformation learned through reverse engineering may be made available to others for the solepurpose of achieving interoperability, so long as doing so isn’t infringing.
  33. 33. encryption research: breakdown✪  Lawfully obtained the program, and✪  Circumvention is necessary to conduct the research, and✪  Good faith effort to obtain authorization before the circumvention, and✪  Not infringing.
  34. 34. encryption research: other factors✪  Was the information disseminated, and if so, in a way reasonably to advance the state of knowledge, or to facilitate infringement or violate other laws?✪  Is the researcher studying, trained, experienced, or employed in the field of encryption research?✪  Did the researcher give the copyright owner notice of the research findings?
  35. 35. security research: breakdown✪  Solely to promote the security of the owner of the device, system, or network, with the owner’s authorization, and✪ Information learned isn’t used to facilitate infringement or violate other laws.✪  Tools created for the sole purpose of security testing are OK if they don’t otherwise violate the ban on distributing tools.
  36. 36. PII: breakdown✪  The TPM or work it protects can collect or disseminate personally identifying information, and✪  The person whose PII is at issue is the one circumventing, and✪  Sole purpose to identify and disable PII collection/dissemination.
  37. 37. a few words about jailbreaking✪  Library of Congress made clear in 2010 that jailbreaking phones doesn’t violate the DMCA.✪  Doesn’t apply to jailbreaking other devices (at least, not yet).✪  Doesn’t authorize the distribution of jailbreaking tools.
  38. 38. communication laws
  39. 39. laws that might apply✪  Eavesdropping laws ✪  Wiretap Act (18 § U.S.C. 2510 et seq.) ✪  State laws✪  Laws protecting addressing/routing information ✪  Pen Register Act (18 U.S.C. § 3121 et seq.) ✪  State laws✪  Laws protecting stored communications ✪  Stored Communications Act (18 U.S.C. § 2701 et seq.) ✪  State laws
  40. 40. watch out for✪  Inspecting packets without consent of the parties (note one-party vs. all-party consent).✪  Breaking encryption or descrambling.✪  These laws are outdated and confusing. It’s worth checking in with a lawyer if your research involves looking at communications, even just routing information.
  41. 41. designing safer research
  42. 42. ✪  Identify and read any applicable agreements before you begin your research.✪  Don’t agree, if possible.✪  Test on your own devices/accounts/data/ communications.✪  Get permission to access the device/accounts/ data/communications.
  43. 43. ✪  Make sure that the copy of the software you’re studying is legally acquired.✪  If you make a copy of someone else’s code, make sure that you need it to understand how the program functions, and don’t copy more than you have to.✪  Avoid making copies of code for a purpose other than analyzing how a program works.
  44. 44. ✪  Talk to a lawyer before breaking crypto, descrambling, or bypassing other security measures.✪  When studying others’ code, consider asking permission, even if you don’t think you’ll get it.
