Appeals Court Says That Sharing Passwords Can Violate Criminal Anti-Hacking Laws
from the wait-just-a-second... dept
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 filed new CFAA 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:
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.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."
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 court later repeats that it's the combination of this password sharing with the fact that Nosal's own, earlier access, had been revoked that makes this a clear "without authorization" situation:
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.”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:
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.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"?
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.The dissent further notes that this ruling appears to conflict with the ruling in the first Nosal case:
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 also calls out the hand waving by the majority:
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.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.
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.Either way, after this ruling, there's at least a lot more legal uncertainty and liability in sharing passwords. And that's unfortunate.
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.

This seems like a clear case of social engineering
It's getting access to the system that would not have been allowed from an inside employee.
If this isn't covered, is spear phishing allowed too?

The answer is yes.
So you're also violating the CFAA for helping your 12-year-old daughter create a Facebook account, incidentally.
To be fair, it's very difficult for anyone to not commit CFAA felonies.
Thank our Constitutional Framers for prosecutory discretion, so no one important ever has to suffer a CFAA indictment.

It's a bad week on Techdirt for over reach and over reading court judgments. The conclusion in this story is Fox News in "quality".
Part of the problem here is that you seem unwilling or unable to accept the concept of intent. The password was given out with the intention of hacking, causing harm, or otherwise illegally accessing the system. The intent is there.
Sharing your gmail password with your brother won't get you sent to jail (unless of course you have magically conspired to hack gmail).
Techdirt use to be pretty good with this stuff, but more and more, it seems you are more worried about riling up the troops and a lot less about drawing sensible conclusions.

I think the court ruled correctly
It seems pretty much the same as if you have a a key to your workplace and lent it to someone who was specifically prohibited from access.
That seems sensible and logical to me, and doesn't seem to comment on the more usual password-sharing events such as sharing your personal email password with a friend.
[ link to this | view in thread ]
Re: I think the court ruled correctly
So in some cases, such a clause is intended to protect the end-user by making it criminal to coerce someone to disclose their password.
Ideally, sharing your email account password with a friend could fall into the no-harm-no-foul category, but I can easily see some official pushing prosecution via the CFAA if he wanted to dispose of someone.

Re: This seems like a clear case of social engineering
Through trickery or peer pressure the end result is someone who did not have access obtained access he was not entitled to have.

Re: I think the court ruled correctly
The point here is along the lines of: a significant number of web services (particularly financial services, but also things like email, streaming, etc.) include in the TOS a statement that only the account holder (or account holder and household, or some other variation) is allowed to access the account. That is, everyone except the people listed are specifically prohibited from access.
Thus, while the court didn't broadly rule that sharing passwords is a crime, the majority of password sharing does actually fall under this ruling due to how common services are set up.

Re: Re: I think the court ruled correctly
I think the courts, in this case, have made the right decision and this decision would only apply to similar future cases. Sharing the password of your personal email account with a friend is NOT a similar case.

Right target, wrong reason
1) Man leaves company1 to start competing company2
2) Man, now owner of company2 convinces a current employee of company1 to provide key to building of company1
3) Man enters company1 and records proprietary data without permission and leaves company1 as he found it
This is essentially what happened. In reality he should be prosecuted for a) trespassing, and b) corporate espionage, both of which are illegal. So the feds is going after the right man for all the wrong reasons.
We do not need new laws, we need common sense applied to existing laws and removal of duplicate laws. Trespassing is already illegal. Peeping is already illegal. We do not need new laws to prosecute people for performing these acts digitally.

Don't confuse having a password with being "authorized"
The court is looking at the question of "authorization" in legal terms, not technical terms. And in legal terms, the former employee was clearly not authorized to access the computer. Only the company has the right to grant access in this case, and that access was unambiguously revoked. The buddy who shared his password did not have the legal right to grant access, and so it does not constitute "authorization."
So even though the former employee might have gotten a password, that does not make him "authorized" in the legal sense. The current employee who gave him the password did not have the authority to grant access. I think any other interpretation of the law would make it almost impossible to prosecute for any kind of hacking that involves tricking someone into disclosing a password.
The reason this can seem wrong is that it's easy to confuse "authorized" in the technical sense of the word (i.e. did the computer grant you access?) with "authorized" in the legal sense (i.e. did someone with the legal authority to do so give you permission to access the computer?).
A real-world analogy would be a secured office building. Only certain people have permission to grant access to the building. If you get fired from a company and they take away your keycard and tell you you're not allowed in the building anymore, it would still be trespassing if you borrowed a buddy's keycard to get in.

Re:
Citation required on the first 2, although the third is acceptable to some degree. From what I've read, the only intention was to access the data within, not to change it or access other parts of the system.
"Part of the problem here is that you seem unwilling or unable to accept the concept of intent"
"Sharing your gmail password with your brother won't get you sent to jail (unless of course you have magically conspired to hack gmail)"
Depends on the intent, by your own admission, doesn't it? Accessing GMail won't let you hack it - but, then, accessing this database with normal user privileges won't let you hack it either. Once you get over that idiotic statement, it's easy to see that accessing GMail may violate T&Cs, and that's the only standard really being addressed directly here. Sure, intent is a factor, but then so it is in GMail access to a third party. There's no argument you can use here that's not applicable there.

"What about an employee who creates passwords and disseminates them to his colleagues on a regular basis for legitimate business reasons? "
Whether or not that's OK depends on the employer's policies. For instance, at my last employer the policy was that all credential sharing was prohibited (and a firing offense) under any circumstances. There is never a legitimate business reason to do so.

As for PaulT:
"accessing this database with normal user privileges won't let you hack it either"
If you are accessing it yourself with your password given by your employer when you are still working for the company, it's not hacking (illegal access). Once you are fired, or when you are using someone else's password (social hacking or otherwise) then you have crossed the line.
I can't imagine that simple concept is too hard to understand. Try thinking about it for a couple of weeks and check back with us once you earn your gold star in basic English.
