How to Protect Yourself from Thermal Attacks: Computer Experts Share Tips

(Image credit- CTV News) Several recommendations have been made by a group of computer security specialists to protect against "thermal attacks," a technique that uses heat-sensitive cameras to collect user information from computers and smartphones.

How Thermal Attacks Work

Thermal attacks involve the use of heat-sensitive cameras to find any remaining fingerprints on surfaces like smartphone displays, keyboards, and PIN pads. By examining the degree of heat traces left behind on previously touched surfaces, hackers can piece together user passwords.

They unveiled ThermoSecure, an AI-driven platform that quickly derived passwords from heat-trace photos, therefore significantly raising public awareness of the threat posed by thermal attacks. In order to prevent thermal attacks on public payment devices, such as ATMs and ticket machines, the same research team has evaluated computer security practices in great detail and conducted surveys to gather user preferences. A paper describing their findings will be presented at the next USENIX Security Symposium conference. The group also came up with 15 different techniques for lowering the risk of thermal attacks.

How to Avoid Thermal Attacks

The recommendations cover a wide range of actions, including putting up physical barriers to protect keys until the heat subsides, using hardware and software solutions like heating elements to remove traces of finger heat, and wearing gloves or rubber thimbles to reduce heat transfer from users' hands. Software updates for existing devices could act as a reminder for consumers to be watchful for thermal camera surveillance. Khamis emphasized the significance of the engagement of thermal camera manufacturers, arguing that implementing new software locks to prevent photos of delicate surfaces might thwart attacks. In the end, our advice to the general public is to try to identify one method that works for their unique routines and behaviors and to use it as frequently as possible in their daily life. It will be more difficult for others to acquire their personal data if they frequently take steps to protect themselves from thermal attacks, Khamis stated.
