Google Announces "Password Alert" To Protect Against Phishing Attacks

HughPickens.com writes: Google has announced Password Alert, a free, open-source Chrome extension that protects your Google Accounts from phishing attacks. Once you've installed it, Password Alert will show a warning if you type your Google password into a site that isn't a Google sign-in page. This protects you from phishing attacks and also encourages you to use different passwords for different sites, a security best practice. Once you've installed and initialized Password Alert, Chrome will remember a "scrambled" version of your Google Account password. It only remembers this information for security purposes and doesn't share it with anyone. If you type your password into a site that isn't a Google sign-in page, an alert will tell you that you're at risk of being phished so you can update your password and protect yourself.

      What I'd really like to see is a keychain helper (listening, Apple, onepass, etc?) that keylogs browser forms and performs this function against ANY password stored in the keychain. I mean, I've already got a keychain full of password/uri pairs -- why not do this with it as well?

      The downside of course is that said helper would have to have full read access to the hashed keychain -- which while not a huge security issue, still could leak data like what uris you have stored in the keychain.

      Yeah, if it were integrated with something like password safe or password gorilla or keypass etc.

      Or I suppose it could be tied into the A/V products which already have anti-phishing extensions -- McAfee for example, already has a password safe and antiphishing ... seems almost a no-brainer for them to integrate them in this way. The password safe component could dump a list of hashes and domain names and if you try entering a password that matches the hash throw up an alert. And then maybe flag the page for A/V's phishing lists so if a page is generating alerts like crazy visitors it can be blacklisted -- preventing other users from even reaching the domain/phishing page.

      Some fraction will use a harder patterns that aren't immediately obvious. That's an improvement. Lets say my password is "stupidgdog" for google. Maybe your automated phishing tools will try stupidfdog on facebook... but maybe not.

      Lets say I use stupidgHdog as my google password. My new pattern is still simple. its "stupid" + "first name of domain" + "next letter in alphabet capitalized" + "dog"

      With just one sample, are you really sure your automated phishing tools going to figure out that facebook is: stupidfGdog ? And twitter its stupidtUdog?

      And that's still pretty lazy as passwords go.

      Here... I give you twitter on this pattern too: N47.8Vanadium.
      With 2 samples passwords you've got enough of a pattern to try and brute force it... letter + 3 digits + element... 26* 1000 * 118... 2.6 million passwords to try.

      Very doable if its a targeted search on a particular user... but your probably not going to spend the time looking at each fished password and then write a script to do that specific search... for just one random user. Probably.

      Not exactly. The 37-bit version is just less than 25% of the full 160-bit SHA-1 so, as the source mentions (https://raw.githubusercontent.com/google/password-alert/master/SECURITY.md) the intent is to keep enough of the password to tell when the same password has been tried twice, but not enough of the hash to allow someone to authoritatively crack it.

    So like the cops... it shows up only after the crime has been committed, and only protects some of the population (Google passwords) and not the rest of the population (e.g. your banking password isn't protected, because it's not a Google site).

    Seems slightly less than useful.

    I disagree.

    If you use Gmail as your primary e-mail then your Google password is the crown jewel of your online identity, since every other site out there (including your bank) uses e-mail as the password reset channel. Sure it might be nice if the tool were more general-purpose (though that would require changing the hashing strategy, which intentionally uses relatively few bits as a security measure to protect against brute force), but if you can protect only one password, your e-mail password is the one.

    For people who use not just Gmail but lots of Google services, it's even more critical. I store lots of important stuff in Drive, have my phone report my exact location, have my whole address book synced, etc., etc. It doesn't concern me to have so many eggs in one basket because I trust Google to maintain good security, but it can only be as good as my authentication. I use 2FA, but there's still value in being careful with such an important password.

Secondly, it needs to be generalized: Just as browsers currently ask "Would you like to save this username/password for www.somesite.example", they should also ask "Would you like to lock this username/password combination to www.somesite.example?" and offer the usual "Yes / No / Not now" choices.
