In Athens Greek police officers detained two Chinese citizens aged 29 and 31, who, according to investigators, used a particularly sophisticated wire fraud scheme known as SMS Blaster Attacks.
According to the police, the detainees created a mobile system for mass distribution of false SMS messages, exploiting vulnerabilities in mobile communication networks. Using high-tech equipment, they intercepted the mobile phone connections of passers-by and sent them phishing messages, masquerading as banks or courier companies.
The attack device was hidden in the trunk of the car. The machine actually functioned as a mobile cyber laboratory, allowing attackers to change locations and attack users in different areas.
What are SMS Blaster Attacks
SMS Blaster Attacks belong to the category attacks type man-in-the-middle. Criminals create a fake mobile phone base station (IMSI catcher) that tricks nearby phones into connecting to a fake antenna.
- mobile phones automatically connect to the fake station;
- connection is forced to switch from 4G to 2Gwhere serious vulnerabilities exist;
- attackers obtain basic subscriber identification information;
- Bulk sending of false SMS is carried out without the participation of the telecom operator.
Specially equipped vehicle
The suspects’ car was equipped with a mobile computer system with Internet access, a specialized transmitter-antenna on the roof in the shape of a “shark fin”, as well as software for creating fake mobile communication base stations.
How victims were deceived
After intercepting the connection, the attackers sent SMS with phishing links, posing as banks or delivery services. The victims were convinced to enter bank card details, personal information and access codes.
The obtained data was used for illegal purchases and financial transactions.
Detention and investigation
The suspects were identified on April 9, 2025 in the Spata area of eastern Attica. During the check, they presented fake IDs.
During a search of the vehicle and personal belongings, a specially equipped vehicle, electronic equipment and five mobile phones were seized.
At least three episodes of fraud are currently being investigated in the areas of Maroussi, Spata and Athens. The investigation continues to establish the full extent of the criminal activity.
The detainees were transferred to the competent prosecutor and are accused of fraud, forgery of documents and illegal access to information systems.
