Google has started warning users when it thinks they may be targets of government-sponsored hackers, the Internet giant announced.
Users whose accounts are compromised get a message at the top of their browser saying: "Warning: We believe state-sponsored attackers may be attempting to compromise your account or computer."
Google declined to say how it could tell that governments were behind the hacking attempts, or to say which governments it blamed.
"We can't go into the details without giving away information that would be helpful to these bad actors, " Google security engineering vice president Eric Grosse said in a post on the company's website on Tuesday.
"But our detailed analysis - as well as victim reports - strongly suggest the involvement of states or groups that are state-sponsored," he said.
Getting the warning does not mean a user's account has been hacked, the company said, but that Google believes the account has been a target of phishing, malware or other hacking tools.FULL STORY
