Possibly exploitable before July?
I was one of the "lucky" few who had their accounts hacked. I took a look in the "Logins and Logouts" section of the Activity Log (which is buried about 6 clicks deep) and spotted that there had been lots of logOUTs from China, Adis Ababa, Russia, Vietnam, etc. since June and possibly earlier (no data before the end of May because, GDPR). No logins from these locations at all, so I received no warnings - presumably Facebook only checks for suspicious logins only (and warns if the appropriate setting is enabled) and ignores logouts altogether, so I was none the wiser.
Has anyone else spotted the same pattern in their Facebook login/logout history? Curious to know if anyone else had this activity prior to July.
