PROTECTION OF SMARTPHONES FROM THE INFLUENCE OF HARMFUL PROGRAMS DURING CHARGING IN PUBLIC PLACES

Abstract

As smartphones become indispensable tools for communication, work, and entertainment, the risks associated with their frequent charging in public places such as cafes, coworking spaces, and power bank rental stations have significantly increased. This publication aims to analyze the growing cybersecurity threats to mobile devices, particularly the vulnerabilities linked to public charging stations and USB data transfer devices. Various cyber threats are examined, including Juice Jacking, BadUSB attacks, rental power bank compromises, and the deceptive safety of public USB ports, which may be configured to deploy malware or conduct unauthorized data access. Detailed descriptions of various attack vectors are provided, along with practical measures to mitigate these risks. Recommendations include using personal chargers, employing USB cables or devices that block data transfer (USB condoms), and the importance of regular software updates to protect against known vulnerabilities. A novel solution proposed is the development of a USB-C to USB-C keychain with disconnected data transfer contacts, ensuring charging without data transfer risks, and a fuse that can provide additional protection against voltage spikes and direct hardware attacks such as BadPower. The keychain blocker is designed for easy portability, attaching to key rings or directly to smartphone cases, ensuring availability when needed without the risk of being forgotten. The article argues for increased awareness and preventive practices as integral components of cybersecurity in an era when mobile devices are widely used and continuously exposed to growing threats. The research results highlight the inevitability of complex cyberattacks amid global tensions and technological advancements, advocating for proactive measures to protect personal and confidential data. Continuous software updates and the use of hardware solutions designed to secure mobile devices effectively protect users from most cyber threats.
