1.2 million Americans were contacted after phone numbers were stolen from hackers.
Indian law enforcement have arrested 772 individuals after they conducted raids against several U.S. Internal Revenue Service (IRS) scam centers.
On 4 October, 200 Indian police officers raided nine call centers in Mumbai where they believe hundreds of people impersonated United States tax collectors.
The call centers first obtained the phone numbers of ordinary American citizens from groups that traffic in people’s stolen data.
Using that information, staffers at the call centers reached out to their targets via Voice over Internet Protocol (VoIP) while posing as IRS officers. They told victims they owed money, and they said police were on their way to arrest them or seize their house if they did not reveal their banking details.
