Google's Gmail is vulnerable to a security exploit that might allow hackers full access to your email account simply by knowing your username, according to
Nana Netlife Magazine:
"Everything could get publicly exposed – your received mails might be readable, as well as all of your sent mail, and furthermore – anyone could send and receive mail under your name", thus reveals Nir Goldshlagger, an Israeli hacker, on an exclusive interview with Nana NetLife Magazine. "Even more alarming", he explains, "is the fact that the hack itself is quite simple. All that is needed of the malicious hacker, beside knowledge of the specific technique, is quite basic computer knowledge, the victim's username – and that’s it, he's inside".
Google admitted to the security flaw and is working on a fix.
One tip for Google: Stay beta forever, then you don't have to bother with legal claims at the end.
