In a narrow lane of Hyderabad’s Hafiz Baba Nagar, a small, unremarkable house became the unlikely command post of a global cybercrime network. What looked like a regular Wi-Fi router on a kitchen shelf was, in reality, a SIM box — a device that quietly routed hundreds of international calls from Cambodia through local mobile networks, enabling fraudsters to pose as Indian law enforcement officers and extort money from victims across the country.
Police say the setup was operated by 28-year-old Hidayatullah, who was arrested along with two accomplices. Investigators found more than 500 SIM cards inside the house, 80 of which were active and plugged into the device. For months, Hidayatullah followed instructions from a handler based in Cambodia, swapping SIM cards, checking power connections and resetting the device — all while his unsuspecting family cooked meals just a few feet below.
According to The Hindu, Hidayatullah was once a car dealer whose life spiralled into debt after failed investments and addiction. Desperate to recover his losses, he was drawn into the scam by a contact who introduced him to a woman named Venisa in Cambodia. Her instructions were simple but criminal: install a SIM box, feed it with SIM cards, connect it to broadband, and keep it running. Each blinking light meant profit, as every call helped fraudsters impersonate government agencies and terrify victims into parting with their savings.
The Telangana Cyber Security Bureau (TGCSB), working with the Department of Telecommunications, uncovered this racket in September after tracing suspicious call activity. Their investigation revealed that Hidayatullah’s kitchen was only one node in a much larger network spanning multiple states. In a similar case in Mancherial district’s Jannaram, another SIM-box setup operated from a rented room, routing calls that triggered at least 14 “digital arrest” scams across India — 11 in Telangana and others in Delhi, Uttar Pradesh and Tamil Nadu.
Among the victims was a 76-year-old retired government doctor from Hyderabad, who received a call from fraudsters posing as Bengaluru police. Over three days, she was accused of crimes, shown fake court and RBI documents, and coerced into transferring ₹6.6 lakh. Overwhelmed by fear and stress, she suffered a cardiac arrest and died soon after — a tragic reminder of the human cost of such scams.
Officials say SIM boxes are at the heart of a growing fraud ecosystem that manipulates India’s telecom infrastructure. These devices can hold dozens of SIM cards and convert international VoIP calls into local ones, masking their true origin. Fraudsters buy SIMs in bulk using fake documents or through corrupt point-of-sale agents, often exploiting migrant workers’ identities. Once used, the cards are quickly destroyed to erase evidence.
Investigators admit that tracing these networks is a technological and logistical challenge. Weak mobile coverage, poor Know Your Customer (KYC) checks by telecom operators and slow coordination between banks, telecoms and police often allow scammers to stay one step ahead. Most SIM cards used in the scams were from BSNL and Vodafone networks, officials said, as these operators’ lower traffic and outdated systems made detection harder.
With Telangana alone reporting over ₹55 crore in losses from cyber scams this year, police are intensifying efforts to detect and dismantle SIM-box setups. Authorities urge citizens to remain alert to unknown calls claiming to be from the police, courts or government agencies — and to verify identities before taking any action.
As The Hindu reported, the blinking device on a kitchen shelf in Hyderabad was more than just hardware — it was a symbol of how cybercrime has entered the most ordinary corners of Indian life, turning homes into hidden frontlines of a global digital war.
