Backblaze verzeichnet erhöhte Zugriffe auf die Loginbereiche und empfiehlt seinen Kunden, die Passwörter zu ändern und die Zwei-Faktor-Authentifizierung zu aktivieren.
Over the last 72 hours, our security team has noticed an increase in automated attempts to log into our users’ accounts using credentials stolen from other websites. […] we live in an era where companies have been breached and their customers’ credentials have been leaked – Dropbox, Adobe, and LinkedIn are just a few, high profile examples. What happens in these attacks is that the attacker acquires “the Dropbox list” and simply tries those usernames and passwords on another site. If your credentials were leaked in one of those hacks and you used the same username/password combination to sign up for other services (such as ours), you are vulnerable.
Die Wiederverwendung von Logindaten bei mehreren Services ist fahrlässig. Punkt.
