Greek police have arrested two people over an alleged scam that saw the suspects drive around with a makeshift cell tower in the trunk of their car.

As reported by Cyber News this week, the two foreign nationals were arrested last year after being caught with gear that allowed them to breach user devices and send phishing messages.

It's reported that the two suspects are part of a criminal group that is believed to be responsible for a large-scale fraud, according to the Hellenic Police.

The trunk of the car was fitted with a mobile computer system with Internet access, connected to a transmitter placed on the roof. Police said that the gear inside the trunk functioned as a clone of a mobile phone antenna, mimicking a mobile phone base station.

The authorities noted that the alleged scammers used this equipment to operate an SMS blaster, which is a device, often portable and disguised as a mini cell tower. These are often used by scammers to pose as legitimate telecom infrastructure.

Once a target device was connected to the dummy antenna, the attackers downgraded it from 4G to 2G. This allowed the suspects to exploit a legacy 2G vulnerability, which exposed ID data, such as device phone numbers.

From there, the suspects sent phishing messages to users, often impersonating banks or mobile carriers. They would redirect the victims to a fake website that required them to enter banking details.

The two people, aged 29 and 31, were both arrested in April 2025 in Spata, a town near Athens.

Last week, Greek authorities noted that a further three fraud cases in Spata, Athens, and Maroussi, another town close to the Greek capital, have also been uncovered.
