Czech IT experts and banking officials are warning citizens about the increasing risk of malware infections contracted while traveling abroad. The warnings specifically target the use of public Wi-Fi networks and shared charging stations, which can be exploited by cybercriminals. Banks estimate over 20,000 customers may have been affected by this type of attack during the summer months alone. These infections often lead to the theft of personal data and financial losses as attackers gain access to victims’ devices. Authorities advise caution when connecting to unfamiliar networks and avoiding public charging points. Travelers are encouraged to use secure, private connections and personal charging devices whenever possible to mitigate the risk. The increasing trend highlights the growing sophistication of cyber threats targeting mobile device users.
