In light of the recent security breach that exposed around 450,000 Yahoo users’ e-mail addresses and passwords, security firm Sucuri has set up a tool you can use to check whether or not your account information has been leaked.
Here’s a link to the tool: http://labs.sucuri.net/?yahooleak
It’s being reported that some non-Yahoo e-mail addresses have been affected as well, so check any other e-mail addresses you use, too.
If your data has been compromised, you can change your Yahoo account password here: https://edit.yahoo.com/mc2.0/eval_profile – though in a company statement, Yahoo says it’s changed the passwords of affected users already.
Here’s the statement in full:
At Yahoo! we take security very seriously and invest heavily in protective measures to ensure the security of our users and their data across all our products. We confirm that an older file from Yahoo! Contributor Network (previously Associated Content) containing approximately 400,000 Yahoo! and other company users names and passwords was stolen yesterday, July 11. Of these, less than 5% of the Yahoo! accounts had valid passwords. We are fixing the vulnerability that led to the disclosure of this data, changing the passwords of the affected Yahoo! users and notifying the companies whose users accounts may have been compromised. We apologize to affected users. We encourage users to change their passwords on a regular basis and also familiarize themselves with our online safety tips at security.yahoo.com.
