Opera Backstage: Opera 9.1 will include Fraud Protection
By borg. Tuesday, 17. October 2006, 13:11:05
As presented at the Opera Backstage event in London today, Opera 9.1 will include enhanced fraud protection. Today we display the name of the certificate owner in the right end of the address field when you're on a secure site. In 9.1 we will reuse that field to display more information about the trust level of the site you visit.

When you go to a new site for the first time, Opera will check against a database if the site is trusted or if it is a known fraud site. If we know the site, there will be a small information "i" in the right end of the address field. If it's unknown/not verified there will be a "?" and if it's known as a fraudulent site we will display a warning and block the user from accessing the site.
The browser sends only the minimum information the database needs to identify a fraud site. When a result is received by the browser, it will be cached there for some time, so it doesn't have to check again if you go to the same site often.
- Why don't we use a downloaded blacklist like Firefox 2?
Firefox 2 only checks against a blacklist unless you turn on real-time protection from Google or other providers. We feel that only real-time protection is real protection, since phishing attacks tend to be more and more like virus attacks, most of their damage is done in a very short time.
- Why don't we use a downloaded whitelist like IE 7?
This makes some sense, especially to save bandwidth for our servers. But for the privacy-concerned user, we don't think it changes anything, since it's typically the more obscure sites that you really want to keep to yourself. We've made it easy to turn on and off the fraud protection from the information dialog you get when clicking the icon.
More technical details:
When you browse to a site you have not visited before, the browser sends a request for site information to our server. The requests contains the domain name of the site and a hash value of the URL. We don't send the full URL, but we need a fingerprint of the full URL in case you visit a dangerous page on a site that is otherwise harmless.
The reply from the server is an XML document containing the trust level of the domain. This reply will be cached by Opera for a time indicated by our server. This means that information about well-trusted sites can be cached for a longer period than for unknown sites.
We don't store information on our servers that let us track individual users. IP addresses are discarded and we don't use cookies or other session information. No information goes directly to third parties, all communication goes through our own servers. Our servers get the trust information from a database supplied by GeoTrust, who have a long experience with anti-fraud solutions.
The requests go over HTTP, but the replies will be signed by the server to make sure they are genuine. We prefer to send information between the browser and ourselves in plain text, so our users can inspect the data we send "home".

Can this be disactivated?

Will there be demo URLs for use to play around with so we can see the expected behavoir?
By Eddie_Lopez, # 17. October 2006, 19:26:13
This sounds very cool. Although I believe that common sense is the greatest defense, this will prevent mistakes and hopefully eliminate (or greatly reduce) people entering bank details into fraud sites.

By larskl, # 17. October 2006, 19:30:00
We can publish demo URLs for the blocking screen, yes.
Common sense is the best defense, and many of you here may not need it, but when we install Opera for our friends and family it's an extra layer of protection.

1. minimize to tray when closing,
2. editable User Agent string - usefull for example in phpBB with OS icons, when I want to be more specyfic (Gentoo Linux instead of Linux x86_64).
Both don't require much coding.

It adds even more clutter in addressbar. RSS, widgetize and now trust level. I have other items on my address toolbar and my address input box is getting too short
GeoTrust probably doesn't have information about most websites I visit, so I'd have [?] in UI most of the time. I find this symbol intriguing and calling for attention. I'd prefer more neutral UI (nothing added to addressbar?) for unchecked websites.
Why send domain in clear text and not hash as well?
Whitelist of safe domains makes sense to me. With 16 bytes per domain hash, you can include plenty in the default install.
BTW: is that a full-blown pop-up window? Will it be modal or always-on-top? If not, what if user clicks main window? What if user closes or navigates away from suspectd page without closing alert?
How about alert made similar to "block content" toolbar?

The warning takes over the entire tab, so you really can't miss it. Even if you choose to continue to the fraud site, the right end of the address bar will be red and display a warning.

@Eddie_Lopez: You'll get your chance to try it out pretty soon..
By borg, # 17. October 2006, 20:31:41
Well.. I'm suspicous by nature. My father told me not to take things at face value and to get out and try and explore them myself.
So if you'll just email me the installer for 9.1, we'll get to the bottom of this.
By Eddie_Lopez, # 17. October 2006, 20:33:16
and what about compatibility ?

Will the "delete private data" feature be updated to delete the .xml file with this cache data?
While this could be very helpful in protecting users, I can see a lot of users worrying about the fact that every site someone visits gets sent to Opera.

Basically, there are two types of users: Those who are so careful about their privacy that they don't want or need the extra protection, and everyone else.
On the other hand, even if I don't feel very vulnerable myself, there is some "entertainment" in seeing if the site I visit is among the verified ones or not

wha? I'm just *very* security minded. I'm very concerned about the safety of my fellow Opera-teers
As such, I throw myself on the sword of risk... headstrong into the fray (against the wishes of Frey) and prostrate my browsing environment before the whims of the company to test the choppy, sometimes indiscernable waters of phishing,scamming, and uncertainty.
I do this for my fellow Opera browsers in the name of... ah heck, the weekly will probably be release before finish this.

And we will of course keep a careful eye on the feedback.

Congratulations!!!
I have one suggestion:
- Desktop Search (like Copernic or Yahoo) plugin in Opera.
- Integrated anti-spy and anti-adaware Widget like in Nestcape 8.1.2
- Instant Messenger Widget multi-client (Yahoo; Google Talk; Gabber; MSN Messenger;...).
- ;-)

Also will you improve JavaScript further in v9.1, so that sites that heavilly relly on JavaScript like Meebo and Digg will work corectlly?
What about the email client will it be updated in the near future as it has been left behind a little.
By Nemok, # 17. October 2006, 21:58:37
As long as I can turn it off (globally), I'll be happy.

By borg, # 17. October 2006, 22:20:33
also, adding on to what paitrakt said, i think the warning page should look like the other opera-generated pages (like for file listing, opera:about, etc).
