Introducing LastPass Sentry: Always on the Lookout for the Latest Breach

By September 17, 2012 Product Updates 62 Comments

In response to a number of high-profile breaches (including LinkedIn, Last.fm, and the Apple UDIDs), we’ve provided LastPass users with tools to check if their data is on the leaked lists, and have notified users directly as we’ve discovered their compromised data. We wanted to take this a step further, and partnered with a company dedicated to finding and aggregating all leaks as they’re occurring, to provide a much more comprehensive service.

Today we’re excited to announce our partnership with PwnedList to offer LastPass Sentry, a new feature that will help LastPass users be more proactive about their online security.

With LastPass Sentry, we’ll use PwnedLists’s comprehensive (and growing) database of 24 million publicly leaked usernames and passwords to perform daily “checks” against LastPass account email addresses to look for positive matches.

How it works:

  1. Sentry performs daily checks, with the latest updates to the PwnedList database, to see if LastPass account email addresses are on the list.
  2. If a match is found, an email notification is sent to the LastPass user, notifying them of the domain that was breached and the potential risk.
  3. Users can then run the LastPass Security Challenge to verify if the password for the breached site is used elsewhere.
  4. We then recommend updating the password for the affected account, and any other accounts using that password, using LastPass to generate a new, strong password.

The feature is available for all free and Premium users, as well as corporate Enterprise users, and is currently opt-out via the email notifications. In the case of Enterprise users, both the Enterprise administrator and the affected employee will receive notifications that a match has been found.

We’re excited that the feature has already generated positive feedback. LastPass Enterprise customer Matthew Wittkin of MoreVisibility commented, “LastPass already helps us to better control and protect our digital assets. With this new feature, our administrators and employees know immediately if any company passwords have been compromised, allowing us to update them within seconds. We hope nothing like this will ever come to pass, but it gives me extra peace of mind knowing that, with LastPass, I’ll be the first to know!”

We have plans to further integrate the service into the LastPass security challenge, so we can check not only the email address that you use for your LastPass account itself, but perform a local check of the entirety of your stored data. We also plan to increase the frequency of our database checks to work towards real-time notifications.

    This is the first time in internet history where making something opt-out was the CORRECT decision! <3 LastPass!

    pwnedlist database synced to my PC?

    Can LastPass let me check the information in my vault against the pwnedlist database locally if I don’t have a local copy of said database?

    How is this supposed to work?

      Currently we only check account email addresses for matches in the database information that we receive from PwnedList. If we were to check the vault, we’d have to sync the data to your machine where the check can be performed locally.

    pwnedlist: Principles Without Principals?

    I find it surprising that pwnedlist.com doesn’t give the names and backgrounds of their key personnel. I understand that they need to be somewhat secretive to get information from hackers.

    I’m practically blind, so perhaps I missed it…
