An archive containing nearly 5 million Gmail addresses and plain text passwords was posted Tuesday on an online forum. The data is old and likely sourced from multiple data breaches according to one security firm. Many of the leaked passwords do not correspond to Gmail or Google accounts, but to accounts on other sites where users have used their Gmail addresses as the user name. A website called isleaked.com allows users to check if their email address is among those leaked. Google says it has no evidence that its systems have been compromised.”]
