Appeals Court Says That Sharing Passwords Can Violate Criminal Anti-Hacking Laws

from the wait-just-a-second... dept

FH had no authority from Korn/Ferry to provide her password to former employees whose computer access had been revoked. Also, in collapsing the distinction between FH’s authorization and that of Christian and Jacobson, the dissent would render meaningless the concept of authorization. And, pertinent here, it would remove from the scope of the CFAA any hacking conspiracy with an inside person. That surely was not Congress’s intent.

Implicit in the definition of authorization is the notion that someone, including an entity, can grant or revoke that permission. Here, that entity was Korn/Ferry and FH had no mantle or authority to give permission to former employees whose access had been categorically revoked by the company. There is no question that Korn/Ferry owned and controlled access to its computers, including the Searcher database, and that it retained exclusive discretion to issue or revoke access to the database. After Nosal’s login credentials were revoked on December 8, 2004, he became an “outsider” and was no longer authorized to access Korn/Ferry computers, including Searcher. Christian and Jacobson’s credentials were also revoked after they left, at which point none of the three former employees were “insiders” accessing company information. Rather, they were “outsiders” with no authorization to access Korn/Ferry’s computer system.

the circumstance here—former employees whose computer access was categorically revoked and who surreptitiously accessed data owned by their former employer—bears little resemblance to asking a spouse to log in to an email account to print a boarding pass. The charges at issue in this appeal do not stem from the ambiguous language of Nosal I —“exceeds authorized access”—but instead relate to a common, unambiguous term. The reality is that facts and context matter in applying the term “without authorization.”

This case is about password sharing. People frequently share their passwords, notwithstanding the fact that websites and employers have policies prohibiting it. In my view, the Computer Fraud and Abuse Act (“CFAA”) does not make the millions of people who engage in this ubiquitous, useful, and generally harmless conduct into unwitting federal criminals. Whatever other liability, criminal or civil, Nosal may have incurred in his improper attempt to compete with his former employer, he has not violated the CFAA.

This narrower reading is more consistent with the purpose of the CFAA. The CFAA is essentially an anti-hacking statute, and Congress intended it as such. Nosal I, 676 F.3d at 858. Under the preferable construction, the statute would cover only those whom we would colloquially think of as hackers: individuals who steal or guess passwords or otherwise force their way into computers without the consent of an authorized user, not persons who are given the right of access by those who themselves possess that right. There is no doubt that a typical hacker accesses an account “without authorization”: the hacker gains access without permission – either from the system owner or a legitimate account holder. As the 1984 House Report on the CFAA explained, “it is noteworthy that Section 1030 deals with an unauthorized access concept of computer fraud rather than the mere use of a computer. Thus, the conduct prohibited is analogous to that of ‘breaking and entering.’” ...We would not convict a man for breaking and entering if he had been invited in by a houseguest, even if the homeowner objected. Neither should we convict a man under the CFAA for accessing a computer account with a shared password with the consent of the password holder.

Worse, however, the majority’s construction would base criminal liability on system owners’ access policies. That is exactly what we rejected in Nosal I.... Precisely because it is unacceptable in our legal system to impose criminal liability on actions that are not proscribed “plainly and unmistakably,” ... it is also unacceptable to base “criminal liability on violations of private computer use policies.”

It is impossible to discern from the majority opinion what principle distinguishes authorization in Nosal’s case from one in which a bank has clearly told customers that no one but the customer may access the customer’s account, but a husband nevertheless shares his password with his wife to allow her to pay a bill. So long as the wife knows that the bank does not give her permission to access its servers in any manner, she is in the same position as Nosal and his associates.12 It is not “advisory” to ask why the majority’s opinion does not criminalize this under § 1030(a)(2)(C); yet, the majority suggests no answer to why it does not.

First, imagine the panel is inclined to rule for Facebook. It could incorporate Nosal II by saying that Facebook is like Korn/Ferry, Power is like Christian and Jacobson, and Facebook’s users are like FH. By that reasoning, Facebook revoked access rights by telling them to go away and by imposing an IP address block on Power. Power could not “sidestep the statute” by relying on permission of Facebook’s users who wanted them to access Facebook on their behalf.



On the other hand, if the panel is inclined to rule for Power, it could easily distinguish Nosal II. It could first say that telling Power to go away and blocking IP addresses is insufficient to revoke access rights because it does not actually cancel any authenticated accounts. If Facebook wants to revoke access, it has to revoke the accounts that have authenticated access — which it hasn’t done — just like Korn/Ferry revoked the accounts of its employees when they left. At that point, Nosal II then offers no guidance because it is expressly limited to revocation. Accessing an account as the legitimate user’s agent is then authorized, just as it would be in a physical trespass case.

Remember David Nosal? He was the former Korn/Ferry executive looking to set up his own competing firm, but one that mainly relied on Korn/Ferry's big database of people. As part of that process, after he left the company to head out on his own, he had some former colleagues who were planning to join him log into their Korn/Ferry accounts to access information. Then after those employees left, they got another former colleague to share her password so they could continue to log in. He was charged with violating the criminal portion of the CFAA, under the theory that convincing his former colleagues to gather info for him was a terms of service violation -- and that meant he had "exceeded authorized access" under the statute. This became a key case in determining whether merely violating a terms of service could be considered criminal hacking under the CFAA. Thankfully, back in 2012, the 9th Circuit rejected such a broad ruling of the CFAA, pointing out that such an interpretation would "unintentionally turn ordinary citizens into criminals" and that couldn't be the intent from Congress. This was a huge win that helped limit some of the worst abuses of the CFAA.However, the US government was not yet done with Nosal. It then filedCFAA charges against him, not over the original information sharing, but rather for getting that last colleague to share her password with Nosal. The feds argued that this fell under the other prong of the CFAA, that it was a version of accessing a computer system "without authorization" (as opposed to exceeding authorization). Unfortunately, the 9th circuit appeals court has ruled that merely sharing a password can be a CFAA violation The underlying question was how can this be unauthorized access since an employee of Korn/Ferry chose to hand over her login info, and thus a fairly strong argument can be made that the access was now authorized -- i.e., it was authorized by an employee of Korn/Ferry. You could argue that that employee (who is referred to in the ruling as "FH") violated the terms of her work agreement, for which perhaps she should have been fired. But it's ridiculous to argue that merely receiving someone's password is a criminal act. And yet, that's what the court decided.It tries to wave away the concerns about the everyday occurrence of password sharing by basically saying "but that's different." It also argues that if an employee handing over a password removes the CFAA, then the CFAA is never applicable to any situations where there's "an insider" helping to get scammers into a computer system:The court's majority ruling insists that this won't harm everyday password sharing... mainly because Nosal and his other colleagues had lost access to the database directly. The reasoning seems to be "well, they once had access, and now they don't, so now they know what they did was wrong."The court later repeats that it's the combination of this password sharingthe fact that Nosal's own, earlier access, had been revoked that makes this a clear "without authorization" situation:That feels a bit like handwaving. It's the court basically saying, "Well, we'd never go after just everyday password sharing, but this is serious!"There's a separate issue of why Nosal is the one facing criminal charges. After all, he's not the one who shared the password! He was just the recipient. The government argues that Nosal "knowingly and intentionally aided" this "crime" of sharing the password. But the court is not too concerned about that, saying that he was in charge and demanded that his other employees "get what I need" in the form of access to Korn/Ferry's database.To me, the dissent argument makes much more sense. This is expanding areas for which law enforcement can throw the CFAA book at people for doing fairly common things such as password sharing:The dissent similarly argues that once an employee handed over the username and password, access was "authorized." It also makes a key point I've tried to raise in the past: if the CFAA is supposed to be about stopping "hacking," why is it always used for situations like this where there was no real "hacking"?The dissent further notes that this ruling appears to conflict with the ruling in the first Nosal case:It also calls out the hand waving by the majority:The dissent is littered with examples of perfectly reasonable password sharing that may now be criminal acts. Orin Kerr, who has been involved in a number of high profile CFAA cases and has been quite vocal on the law, doesn't like the majority's reasoning , though he agrees with the result. I'm not convinced. It still seems to me the issue should be between the company and the employee who handed over the access, not Nosal for receiving such info, from an employee, and then using it.That said, Kerr notes that much more attention should be focused on another case on a related topic -- Facebook's crazy lawsuit against Power.com , an online social network aggregator that used people's logins to collect and aggregate social media posts from a variety of platforms (including, obviously, Facebook). Kerr notes that the court can use this ruling to justify ruling either way in the Power case.Either way, after this ruling, there's at least a lot more legal uncertainty and liability in sharing passwords. And that's unfortunate.
