In the coming weeks, Firefox will begin to warn users when they visit a site that has been part of a data breach.
Whether or not Chinese spies actually planted rogue chips into Super Micro servers, this kind of supply chain attack is feasible. This is just the tip of the iceberg.
Facebook revoked its session tokens after the massive breach. A team of researchers from the University of Illinois at Chicago lay out what attackers could do with those session tokens if they hadn't been reset.
Attackers exploited vulnerabilities in Facebook's code to gain access to at least 50 million Facebook user accounts. Those accounts could have been used for information gathering campaigns, as attackers had full access to the user's profile, friends list, and usage history.
The Firefox Monitor service uses data from the Have I Been Pwned database to alert people to compromises.
