Freaky Leaky SMS: Extracting user locations by analyzing SMS timings
TIL about SMS Delivery Reports and I Googled to learn how to enable them in the native SMS messaging app on my mobile device!<p>I didn't have time to read the whole doc.  Did it say how many SMS Delivery Reports were needed to create the model?  I saw this "We repeated the classification for every combination of locations in our dataset, with sample sizes varying from 100 to 500"<p>I think getting 100 messages from a (series of) unknown number(s) would be alarming, but after reading this, I now know that it's a sign that I need to ... get a new burner phone and increase the size of my security detail?  :^)
