They're attacking the wrong part of the problem. If misleading messages ("phishing") are leading their users to enter credentials onto forms which are then used to send out spam, then the solution is not to block access to one of the sites that supports forms. There are an unlimited number of sites that support forms. There are LOTS of better ways to solve this problem. Here are a few: * Train your users where it is…

> Train your users where it is and isn't safe to enter credentials.

This demonstrably doesn't work. It reduces but cannot eliminate all instances of phishing.

> Don't give your users credentials. Have some alternate way to authenticate them like a login token.

Better, but scrounging up a few million pounds for dongles, plus the non-stop cost and effort of replacing lost and stolen dongles, is not easy for a university, no matter how famous.

> Put rate limiting on the ability of a single account to send out emails.

Many users have legitimate reasons to send out mass emails.

> Instead of blocking the site that was collecting the credentials, a better solution would have been to remove the email from the mailboxes of all the students.

Phishing emails are often varied into multiple templates to avoid being scrubbed this way.

They also tend to trickle in at random, rather than turning up all at once.

I manage barely a 100 users and I have talked to each of them personally. They're good people and can comprehend instructions. But they still fall for these every now and then. Training doesn't help. They are fantastic in their respective fields but to them, all prompt boxes and all login screens have the same exact amount of legitimacy. Just like how every spark plug looks the same to me. Training can help some users but most of them are going to fall for it eventually.

"no alternative way of dealing with the phishing attacks effectively" How about not using passwords? All students, staff, and faculty should have ID cards; start issuing smartcards, and start using cryptographic techniques to authenticate users. Also, digitally sign all official mail, and instruct the users to check those signatures. These are not insurmountable problems. The real issue is that the IT team is not wil…

I also wonder why so many phishing emails are getting through the university spam filters - a slightly better solution might of been to remove links in external emails that point to docs.google.com. But anyway, I don't want to start slagging off a particular team that I've never met - maybe they wanted to do all sorts of other, smarter, things and weren't allowed, and maybe they'll be allowed to do them now..

> I also wonder why so many phishing emails are getting through the university spam filters

It's usually customised for each university.

Misleading headline. They blocked it for a few hours until n people complained. There was more legitimate use than expected, so they unblocked it again.

The real question is, as IT professionals, why would there be more use than expected? Would you expect the premier free cloud competitor to Office to be heavily used? It's as misguided as most of the IT departments I've had to deal with blocking browsers other than IE because they are "insecure". No the other browser are not insecure, they just haven't bothered getting up to speed on the security profile of those bro…

Perhaps you should consider that phrase code for "more use by important management types than expected" rather than mere students and lowly faculty.

It's the perfect example of why security teams are often considered to be the least friendly, least approachable part of an already unapproachable department (IT). Their reasoning seems to be "Google Docs causes us (the security team) hassle, we don't use Google Docs, so we'll shut it down". They might as well of shut down the whole of the Internet, for all their nonsensical reasoning, except they'd of been affected…

No, their reasoning is that the continuous phishing attacks caused unacceptable trouble with their email system (e.g., Hotmail dropping all emails coming from Oxford). Due to extensive international collaborations, keeping a universities email system running is probably one of the most important tasks of the IT team. Google Docs is nice and useful, but nowhere near as important. Given that they, practically speaking,…

"Google Docs are nowhere near as important"

Sure. Which is why after so many people complained it is already back up.

Did you miss the recent articles about how spreadsheets were essential to many people? I know many SMEs and individuals which are doing nearly everything besides email in Google Docs. And what do they use email for? To send PDF of Google Docs to those that don't have GMail accounts.

In the recent "tools of the trade" for HN readers one of the webapp that came out the most often was Google Docs. It is also, quite arguably, seen all its functionalities and seen that it's made by a team of, what, 600 Googlers (!) the most advanced webapp ever.

I think you really don't realize how important Google Docs has become. And it is growing by the day.

There are people who create a GMail account only to get Google Docs after they've seen a demo of it.

I just want to re-enforce your second bullet...

It is 2013, two factor authentication is here and it is open source software. You can use Google Authenticator[1] for free or you can use something like the YubiKey[2]. If the students have a smartphone then Google Authenticator is on almost all of the major platforms.

Yes, they should have known better. Google Docs is used a lot at universities because of its collaborative abilities. If you need to work with several people putting a report together, Google Docs is a great way to get started. We often eventually take it out of Docs into a desktop program to finish it off, but Google Docs is one of the best ways to collaborate. How the IT department didn't know what its students, fa…

> Yes, they should have known better.

As they point out, connections to Google Docs are encrypted. There's no way for them to tell what is and isn't legitimate traffic.
