The link above this is to a report on Mashable that one day after 10,000+ hotmail accounts had their usernames and passwords posted on-line due to a phishing scheme, today the same problem has hit GMail, Yahoo, AOL, Earthlink and Comcast accounts bringing the total number of compromised accounts to over 30,000. Google has already taken steps to correct this by forcing password resets on all affected accounts. All are advised to check their accounts.
