The Strafgericht Baselland has convicted a Chinese man to a 10-month suspended prison sentence for deploying an SMS-blaster to target mobile phones across the cantons of Baselland, Basel-Stadt, and Zürich in October 2025, according to court records. Law enforcement authorities successfully confiscated the mobile phishing hardware and captured the suspect in a rare enforcement action against SMS piracy, uncovering a technique previously unfamiliar to investigators.
Did You Know? An SMS-blaster is compact enough to fit into a backpack or a small suitcase, allowing operators to frequently change their physical locations while broadcasting false signals.
Arrest and Legal Proceedings in Basel
The defendant, who is nearly 48 years old, did not appear before the Strafgericht Baselland on Thursday, having already confessed to his actions and departed Switzerland. Alongside the 10-month suspended prison sentence, the court imposed a five-year ban from entering the country and ordered him to pay more than 40’000 Franken in procedural costs. The case was processed through summary proceedings, eliminating traditional closing arguments in favor of brief statements from legal counsel.
During the proceedings, the defense attorney described his client as a minor, executing driver who had little authority or decision-making power. According to the defense, the man accepted responsibility for his actions, felt remorse, and viewed himself as the victim of a mafiose organization. The prosecutor expressed satisfaction with the verdict while rejecting the notion that the defendant was a victim, noting that although the man received payment for his labor, he obtained none of the illicitly acquired funds.
How SMS-Blasters Target Mobile Networks
An SMS-blaster is a mobile device that mimics the strongest available cellular antenna, prompting nearby smartphones within a 500- to 1000-meter radius to connect to it. Once connected, the device forces the handsets onto an outdated 2G network, exploiting a known vulnerability to dispatch unverified phishing messages without needing the target phone numbers. Between Muttenz and Basel, the operator targeted approximately 100’000 smartphones in a single day using fraudulent texts disguised as Migros and UBS communications designed to capture credit card information.
Investigators admitted that prior to this case, they did not fully understand how SMS-blasters operated or what their range was. Police have studied the confiscated equipment closely and successfully rebuilt it, with the prosecutor noting that he had never seen an SMS-blaster before despite completing a technical university degree. The Kantonspolizei Baselland announced plans to utilize the seized hardware specifically for training purposes.
Tracing the Signal and Next Steps
Pinpointing the mobile equipment proved difficult because the operators moved constantly, but Swisscom cyber threat expert Lukas Benninger explained that the mass connection of local handsets created a distinct traffic pattern. This technical anomaly allowed Swisscom to map the approximate location of the SMS-blaster and provide law enforcement with the critical lead that led to the arrest in 2025. Authorities indicate that the investigation remains active regarding two potential accomplices, as additional personal items belonging to the primary suspect were seized alongside the transmission hardware.
