Jamtara is a city and a notified area in the Jamtara Sadar subdivision of the Jamtara district in the Indian state of Jharkhand. It is the headquarters of the epynomous district, subdivision and community development block. It is also nicknamed the phishing capital of India. It got this title because there were numerous incidents of phishing across country whose centre point was this small town. In the span of two years between April 2015 and March 2017, police from 12 Indian states reportedly made 23 journeys to Jamtara. They did so to investigate cybercrimes — primarily phishing that were emanating from one of the most underdeveloped districts, was responsible for 80 percent of them by some estimates. Those involved had bought luxury SUVs and put up fancy bungalows next to ramshackle cottages.
