Recently my google account was hacked. I have 2-factor authentication turned on. 2-factor authentication was not required for the hacker to gain access to my account, nor did the hacker trigger Google's suspicious activity monitor. This is because the log in was enacted from a "trusted device" or so it seems.
However, the log-in was from a location I never visited with a device name I do not know.
The hacker managed to gain access to my bank account and other various accounts without triggering any of their 2-factor authentication blocks.
One more note: When the attack occurred, the device that I brought with me to Israel and then back to New York, as far as I can tell, was turned off; so it is unlikely that the hacker gained remote access to that device... but then again... maybe they did?
Any idea what happened to me and how I can make sure it doesn't happen again?
(They also managed to get access to my bank account, add a wire recipient (a process I usually have to verify over the phone with a human), and make a successful wire transfer... but let's stick to the Google question)
For the record, I have changed all of my passwords and ran a virus scan that came out without results. But since the 2-factor authentication was enabled on literally all of my services, there wasn't much more I could do.
