The document summarizes recent developments in computer crime law, specifically regarding interpretations of the federal Computer Fraud and Abuse Act. It discusses how courts have broadly interpreted what constitutes unauthorized access, including violating an employer's computer use policies. It also notes problems with prosecutors trying to double-count penalties for unauthorized access by charging it as a felony in furtherance of another crime when it is essentially the same conduct. The future could see legislative changes enhancing penalties for computer crimes.

2. what we’ll talk about today
✪ The federal hacking law and why it’s problematic.
✪ A couple trends that have emerged from recent
cases in which courts have interpreted the scope of
this law.
✪ What these trends suggest about the future.

3. Background
The Computer Fraud and Abuse Act
18 U.S.C. § 1030

4. seven basic prohibitions
1) espionage
2) improperly accessing financial records, government
information, or information on a “protected computer”
3) trespass to government computers
4) improperly accessing someone else’s computer with intent
to defraud
5) causing damage to someone else’s computer
6) password trafficking with intent to defraud
7) extortion

5. improper access
The 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).

6. improper access
Courts have interpreted “obtaining information”
broadly.
Basically any computer connected to the internet is a
“protected computer.”
So the major limiting principle is “authorized.”

7. development 1
expansive theories of unauthorized
access/exceeding authorized access

8. Some people have argued that authorization ends
when an employee violates a duty of loyalty to
an employer...
International Airport Centers v. Citrin
LVRC Holdings v. Brekka

9. Others have gone so far as to argue that
authorization ends when a person violates a
web site’s terms of use.
United States v. Drew
Facebook v. Power Ventures
United States v. Lowson

10. The case law in this area recently took a turn for
the worse when an appeals court found that
violating an employer’s computer use policies
“exceeds authorized access.”
United States v. Nosal

11. The future?
Lee v. PMSI, Inc.
Sony v. Hotz

12. development 2
attempts to double-count penalties for
unauthorized access

13. A first-time violation of the “unauthorized
access” provision is generally a misdemeanor.
However, it can be elevated to a felony in certain
circumstances, like when the offense is
committed in furtherance of another crime or
tortious act.

14. United States v. Drew
Government: felony unauthorized access to a
computer in furtherance of intentionally
inflicting emotional distress.
Jury: no, misdemeanor unauthorized access.
Judge: no, violating terms of service is not
unauthorized access.

15. United States v. Kernell
Government: felony unauthorized access to a
computer in furtherance of unauthorized access
to email and unauthorized access to a computer.

16. United States v. Kernell
Government: felony unauthorized access to a
computer in furtherance of unauthorized access
to email and unauthorized access to a computer.
Do over!

17. United States v. Kernell
Government: felony unauthorized access to a
computer in furtherance of invasion of privacy
and aiding and abetting other unauthorized
accesses to a computer.
Jury: no, misdemeanor unauthorized access.

18. United States v. Cioni
Government: felony unauthorized access to a
computer in furtherance of unauthorized access
to email.
Jury: yup, two felonies.
(This is a problem.)

19. The CFAA prohibits unauthorized access to and
obtaining information from a computer.
(Here, email.)
The Stored Communications Act prohibits
unauthorized access to an electronic communication
service and obtaining stored communications.
(Here, email.)
It’s the same thing.

20. United States v. Cioni
Government: felony unauthorized access to a
computer in furtherance of unauthorized access
to email.
Jury: yup, two felonies.
Appeals court: no, these are misdemeanors.

21. The future?
legislative changes
(enhanced penalties?)
