The companies want to make sure their customers are protected

Earlier this week, researchers from Trustwave reported uncovering a stash of around 2 million credentials for websites, email, FTP and other types of accounts. Some of the companies whose customers had been impacted have already started resetting passwords.

The information, most likely stolen with the aid of malware, included over 300,000 logins for Facebook, around 60,000 for Yahoo, 70,000 for Google, 20,000 for Twitter, 8,500 for LinkedIn and close to 8,000 for the payroll processor ADP.

Representatives of ADP have told IDG News Service that they’ve already reset the passwords of 2,400 customers. Twitter, Facebook and LinkedIn have also checked the information obtained by Trustwave and have taken action accordingly.

It’s not uncommon for major social media websites to check the data from major leaks to see if their customers are impacted. Shortly after the Adobe breach data became available, Facebook started comparing passwords and urging impacted users to change them in case the same ones had been used for both services.

Evernote and others have done the same.
