Just noticed this blog post on Microsoft: "New breakthroughs in combatting tech support scams":

 

On Nov. 27 and 28, over 100 local India law enforcement officials from Gurgaon and Noida raided 16 call center locations identified as engaged in tech support fraud by Microsoft, resulting in 39 arrests so far. These call center operations fraudulently represented themselves as affiliated with a number of respected companies including Microsoft, Apple, Google, Dell and HP.  The New York Times reports that Senior Superintendent of Police Ajay Pal Sharma stated “the scammers had extracted money from thousands of victims, most of whom were American or Canadian.” Microsoft alone has received over 7,000 victim reports associated with these 16 locations from over 15 countries.
