Yesterday I suddenly lost cell service while running errands. Within a half hour I was home. Upon checking my email I found notifications of financial transactions pending (thankfully on a delay). I was able to resolve everything and all is well now but I'm left feeling like I need to rethink all of my online actions. I'm quite careful with my security but once someone took my sim all of my passwords and two-factor authentication went out the window. I was aware of this kind of attack but thought it was relatively hard to pull off. I'm really small potatoes financially and didn't think someone would target me. Apparently it's not all that hard to do this kind of attack. In researching ways to lower my risk I found this article had some good ideas:

Thanks
