Major Cyber Crime Bust in Tamil Nadu: An International SIM Box Network Shutdown
A Significant Operation
The Cyber Intelligence Team at the Cyber Crime Wing Headquarters has achieved a noteworthy milestone by dismantling an international SIM box network that played a crucial role in facilitating Voice over Internet Protocol (VoIP) calls for various cyber scam gangs operating across Tamil Nadu. This operation sheds light on the ongoing battle against cybercrime and the importance of collaboration among law enforcement agencies.
Swift Action and Team Coordination
The crackdown was made possible through critical technical and intelligence insights obtained from an extensive operation led by the State Cyber Command Centre (SCCC). Superintendent of Police, Tmt. I. Shahnaz, spearheaded this initiative, organizing several specialized teams dedicated to addressing the escalating threats of cybercrime.
In a series of high-impact raids targeting specific locations, law enforcement apprehended six suspects from various districts, including Thanjavur, Ramanathapuram, Madurai, and Chennai. The operation successfully dismantled fourteen high-capacity Quectel SIM boxes connected to the scam, found in major cities such as Chennai and Madurai.
Technical Insights
Surveillance Success
The adept use of advanced technical surveillance and comprehensive analysis of telecom traffic patterns was fundamental to the success of the operation. The Expert Technical Team at SCCC worked diligently to trace patterns that led to the identification of the fraudulent activities.
Links to Broader Cybercrime Issues
The seized SIM boxes were not just standalone devices; they were linked to multiple cybercrime cases both within Tamil Nadu and beyond, including incidents in Kanchipuram. This indicates the widespread nature of the network and its potential impact on public safety and security.
Arrests and Modus Operandi
Key Figures in the Operation
Among those arrested were Habeeb Naina (41) from Ramanathapuram and Vinoth (31) from Thanjavur, who were found to be operating SIM boxes that had ties to a supply chain from China. These SIM boxes were stealthily operated within gated communities, such as Urbanrise and Casa Grand in Kanathur, Madurai, and Kelambakkam.
The Financial Web
A Chinese mastermind was allegedly behind the operations, promising commission-based payments to Indian operatives for managing the SIM boxes. However, when payments became irregular, the devices were redirected to Sarath Kumar (27) of Villivakkam, who, with the assistance of his brother Immanuel, opened various bank and trust accounts specifically for laundering the money. They also received help from Saravanakumar, a bank relationship manager at Kotak Mahindra Bank, who reportedly facilitated bribes.
Furthermore, the SIM cards used in the operations were sourced from an Airtel Point-of-Sale store in Madurai, with a staff member named Pandeeswari (25) of Sivagangai being implicated.
Official Reaction
Praise from Authorities
In light of these developments, DGP Shankar Jiwal, IPS, commended the dedicated efforts of the teams involved in this operation. ADGP Dr. Sandeep Mittal, IPS, also urged the public to remain vigilant against potential scams and questionable activities surrounding telecommunications.
Public Advisory
Staying Safe from Cyber Scams
Residents are strongly advised against falling for dubious commission offers related to opening accounts or managing SIM boxes. Homeowners should take extra precautions by verifying the identities of their tenants and monitoring activities in rented properties.
Moreover, be wary of scam calls that may threaten “digital arrest” or involve claims of criminal activity. It’s important to remember that legitimate government agencies will never request money for grievance redressal.
Protecting Personal Information
Individuals should refrain from sharing sensitive information, such as Aadhaar, PAN, and banking details, over any form of communication, including phone calls or video chats. Avoid engaging with unknown individuals—especially via video calls—who may pose as officials, as there is a rising risk of deepfake technology being exploited. Additionally, never install remote access applications like AnyDesk or TeamViewer for strangers.
Reporting Cyber Crimes
If anyone encounters suspicious activities or falls victim to cybercrime, they are encouraged to contact the Cyber Crime toll-free helpline by dialing 1930 or register complaints at www.cybercrime.gov.in. Taking these steps can help authorities combat cybercrime effectively and protect the community from future incidents.
