Since 2012, Google has been
warning Gmail users when they have been targeted by state-sponsored attackers, but now the alert will be even more visible (and therefore less likely to be overlooked or ignored):
The new full-page warning says that Google can’t say how they know that the user’s account is being targeted by government-backed hackers, and urges the user to enable two-factor authentication and set up a Security Key on his or her account.
“These warnings are rare—fewer than 0.1% of users ever receive them—but they are critically important. The users that receive these warnings are often activists, journalists, and policy-makers taking bold stands around the world,” Nicolas Lidzborski, Gmail Security Engineering Lead and Jonathan Pevarnek, Jigsaw Engineer,
explained.
