Police arrest SMS blaster crew that sent malicious messages to thousands across Toronto

In a groundbreaking case for Canadian law enforcement, the Toronto Police Service has dismantled a sophisticated mobile fraud operation that marks the first known instance of an “SMS blaster” used in the country. Since November 2025, three men allegedly operated a uniquely built device from the back of a vehicle, prowling downtown Toronto and hijacking the signals of tens of thousands of mobile devices. By exploiting security vulnerabilities in older 2G networks, the blaster functioned by spoofing legitimate cell towers and broadcasting a signal so powerful that nearby phones were tricked into connecting to it. Once these devices were ensnared, the operators flooded them with fraudulent text messages designed to mimic legitimate businesses, leading unsuspecting victims to phishing sites aimed at stealing banking credentials and personal usernames.

This high-tech scheme reached far beyond simple digital theft; the Toronto Police warned that the device’s interference was strong enough to disrupt local cellular communications and potentially block critical access to 911 emergency services. While similar mobile stations have caused chaos abroad—such as a 2024 incident in Bangkok where a truck-mounted blaster sent a million messages in just three days—this Toronto seizure represents a new frontier for local cybercrime. To combat these “man-in-the-middle” attacks, authorities are urging the public to take technical precautions, such as manually disabling 2G connectivity in their phone settings or, for Apple users, utilizing Lockdown Mode to effectively sever the radio frequency these blasters rely on.
