Gmail Security Flaw Exposes User E-mails
Petko Petkov of "ethical hacking" group GNUCitizen has developed a proof-of-concept program to steal contacts and incoming e-mails from Google Gmail users. "This can be used to forward all your incoming e-mail," Pure Hacking security researcher Chris Gatford said. According to Gatford, attackers could compromise a Gmail account--using a cross-site scripting vulnerability--if the victim is logged in and clicks on a malicious link. From that moment, the attacker can take over the session cookies for Gmail and subsequently forward all the account's messages to a POP account.
