Specialists from the St. Petersburg Electrotechnical University (LETI) have developed a hardware and software complex for automatically detecting cyberattacks on smartphone SIM cards. The system analyzes the device's power consumption to detect suspicious activity.
The development includes four modules: a contact data verification unit, an analysis unit, a control unit, and a crypto module. The methodology is based on power analysis — changes in the gadget's power consumption that may indicate hacking attempts. According to scientists, this allows identifying vulnerabilities in advance and improving the security of SIM cards.
As explained by Anastasia Ponomareva, a junior researcher at the FOIS LETI laboratory, the system can detect attacks aimed at stealing confidential data, such as passwords or encryption keys. Alla Levina, the head of the laboratory, noted that the development will be useful for cybersecurity specialists to protect gadgets from hacking.
The project was implemented with the support of a LETI grant and received a patent (No. 2841287). The university emphasized that the technology can be used to protect not only smartphones, but also other devices with SIM cards.
