I work at Google but not on this product.. so I escalated your issue to the team that works on the anti-phishing classifier. They're looking into it now, and put you on a temporary whitelist in the mean time (should take effect within 30 mins).

Thank you so much. Much appreciated. We will be more than happy to provide additional information or even access to the server if needed.

I opened http://dev1.codelathe.com/ui/core/index.html (URL in your screenshot) in Chrome (latest) but I'm not getting any phishing warning.

I just followed that link in Chrome Version 27.0.1453.116 and did encounter a phishing warning.

Just one more thing. Since our product is self-hosted by our customers under their own domain, white listing just our development domain is unlikely to help our cause.

In fact, whitelisting would tend to hurt your debugging efforts.

It would be nice if the antiphishing filter also gave some good way for web developers to figure out why this happened and what to do to correct this.

This is harder to do than you'd think, without also giving the bad guys a cookbook for "here's how to avoid detection"

No warning on OS X with Chrome 27.0.1453.116

It is because this domain has been added to whitelist which is now overriding it

The whitelisting already active for this domain now.

Here is the output snippet. Basically some "algorithm" thinks it has found phishyness with some score above 0.5 and flags it. No clue as to what caused it (We know that it can be triggered by simply changing the name of the "Login" button to "Connexion"!!

Thanks for the really useful tip to look into Chrome's debug log.

Second, this code and the logic it employs is really bull . The world wide web is not a kiddie playground especially for a browser, and especially for a plugin whose's job is to detect phishing.

As much as I can understand you being upset that Chrome shows a warning for your site, I don't think that the approach they are using is unreasonable.

I'd take bets that those criteria show a correlation to phishy sites. Especially if you combine those metrics together.

Is it perfect? No. Does it produce false positives? Yes. Is it beneficial on average? I think so.

PS: Since you have found the relevant file in the open source project (or 'kiddie playground' - as you like to call it), why don't you supply a superior implementation with less "foolish" measures?

@hiddenfeatures

Yes. Lets apply this everywhere. Lets electrocute folks based on "heuristics" because there are no other way to find out "bad guys".

It is nice to act as an arbiter and spout philosophy isn't it?

If you really do think that there is no other better way then I guess there is no more point arguing about this.
