Hi,
I need your comment and your thought on this.
One of my customer has received twice this week the famous "Microsoft System Security Alert - please call 1-888..." FAKE pop-up page.
The customer has ASA with Firepower + IPS and AMP (file policy, all protocols in download) on all Access Policy rules + Security Intelligence configured. Also, workstations have Fireamp software up-to-date.
Customer concern and mine little bit, how that kind of FAKE warning pop-up can cross all security systems?!
Thanks for your help,
Dominic.
