Cautionary Tale
I'm reasonably careful in interfacing with the 'net. Don't open anything I don't know, don't visit dodgy websites, run virus scans twice a day, change passwords monthly. And access the net thru a dedicated server with filters turned on.
However: yesterday I received an e-mail from an overseas family member who regularly sends me pictures of the kids. Only this time it wasn't from her and clicking on the photos exposed me to an attack which happened ten minutes later, source located in Buenos Aires (so Google told me when they informed me they had blocked an attempt to access my gmail. Well done, Google ! They knew I wasn't in BA because I had Location switched on. And thanks for the automated SMS sent to my phone confirming it).
I'm tell you this because it just goes to show how easy it was for the expletive deleteds to fool me.
And I'm now setting up a system to id the files she (and others) send me as genuine before I open them.
Be vigilent.
