Overview The Central Bureau of Investigation (CBI) has made significant strides in combating cybercrime by arresting three individuals involved in a major network that disseminated phishing messages across the country. These messages were designed to deceive people into falling victim to various cyberfraud activities, including fake digital arrests, loan scams, and investment frauds. The operation, known as Operation Chakra-V , underscores the increasing sophistication and prevalence of cybercrime in India. Key Developments Arrests and Identification The individuals arrested have been identified as Sonveer Singh , Maneesh Upreti , and Himalaya . Their apprehension marks a crucial step in dismantling the cyber fraud network. Operation Chakra-V Under the ongoing Operation Chakra-V against cybercrime syndicates, the CBI meticulously studied a large number of fake SMS messages that individuals receive daily. These messages often lead to serious financial fraud. The investigation identified an organised cyber gang operating from the National Capital Region (NCR) and Chandigarh areas. Modus Operandi This gang was providing bulk SMS services to cybercriminals, who used these services to cheat Indian citizens. Approximately 21,000 SIM cards were obtained in violation of Department of Telecommunication (DoT) rules. These SIM cards were controlled through an online platform to send bulk messages offering fake loans, investment opportunities, and other financial benefits, with the aim of stealing personal and banking details. Legal Action and Investigation Working closely with the DoT and using information from various sources, including the Sanchar Saathi portal , the CBI registered a case against a private company, Lord Mahavira Services India Private Limited . The company allegedly ran the illegal system that allowed fraudsters to send large numbers of fake messages across India. Search and Seizure Searches were conducted at several locations in Delhi , Noida , and Chandigarh . During these searches, the CBI found a complete and active system used for sending phishing messages. This system included servers, communication devices, USB hubs, dongles, and thousands of SIM cards. Using this set-up, lakhs of fraud messages were being sent every day. Evidence and Findings The CBI has seized important digital evidence, unaccounted cash, and cryptocurrency during the operation. Early findings also suggest the involvement of some channel partners of telecom companies and their employees, who helped in illegally arranging SIM cards for this fraud.
