It seems as if the massive phishing campaign reported yesterday was not specific to Hotmail, as was initially believed. According to a report by the BBC, many Gmail and Yahoo Mail accounts have also been compromised. Earthlink, Comcast, and AOL were also affected. While the source of the latest attacks has not been determined, many are pointing to the same bug that claimed at least 10,000 passwords from Microsoft Windows Live Hotmail.
Microsoft has done their part in blocking all known hijacked Hotmail accounts and created tools to help users who had lost control of their email. An analysis of the data from Hotmail showed the most common password among the compromised accounts to be ‘12345.’ On their end, Google responded to the attacks by forcing password resets on the affected accounts.
