Juste pour prévenir Microsoft previent que les certificats du site xboxlive ont été leaké , Et si j'ai compris ils peuvent cloner le site et si vous vous connecter sur ces doublons ils peuvent prendre votre compte ou carte de crédit si vous passez un achat. Si vous voyez un offre trop généreuse méfiez vous

Microsoft accidentally leaked a website security certificate that, if used by an attacker, could open up Xbox users to impersonation attacks.

Buried away in Tuesday's monthly bumper roundup of security updates, the software giant warned in an advisory that the private keys to the xboxlive.com domain had been "inadvertently disclosed," but did not elaborate on exactly how it happened.

The certificate can be used by an attacker to impersonate the xboxlive.com domain and carry out a so-called "man-in-the-middle" attacks, which allows the attacker to intercept the website's secure connection. This could trick Xbox users into handing over their username and password, potentially leading to further attacks on the user.

The good news is that the leaked certificate can't be used to generate new certificates, impersonate other domains, or sign code.

Microsoft said it wasn't aware of any attacks relating to the accidental leak, however.

The company has revoked trust in the certificate, which more often than not is an automatic process for all supported versions of Windows and users do not have to take any action.
