Cybercriminals used a miniature Raspberry Pi computer with a 4G module to penetrate banking infrastructure and steal money. This incident demonstrates new attack methods against financial institutions.

Recently, cybersecurity specialists have been recording an increase in the complexity of attacks on financial institutions. A recent incident involving the use of Raspberry Pi showed how criminals adapt available technologies to conduct large-scale thefts.
Attack Details
Malicious actors managed to physically place a compact Raspberry Pi device equipped with a 4G module inside the banking infrastructure. The device functioned as a bridge between the bank's internal network and hackers' external servers, providing remote access to critically important systems.
The 4G connection allowed criminals to bypass traditional network security mechanisms and maintain constant communication with the deployed device. Raspberry Pi, thanks to its compact size and low power consumption, remained undetected for an extended period.
Penetration Methods
Researchers suggest that the device was installed either through social engineering of employees or as a result of physical penetration into bank premises. After installation, Raspberry Pi gained access to the internal network and began scanning available resources.
Particularly dangerous is the fact that the device could operate autonomously, executing pre-programmed attack scenarios and transmitting stolen data through the 4G communication channel.
Consequences and Damage
The exact amount of financial damage is not yet disclosed, but it is known that hackers gained access to ATM management systems and were able to conduct unauthorized cash withdrawal operations.
The incident emphasizes the importance of a comprehensive security approach that includes not only cyber protection but also physical security of banking premises.
Protection Measures
Experts recommend that financial institutions strengthen network traffic monitoring, implement anomalous device detection systems in the network, and regularly conduct physical security audits of premises.
It is also important to train employees in information security principles and methods for detecting social engineering attempts.
