While you type your pbadword on your laptop or computer, you also leave heat traces that hackers can retrieve and steal your pbadword afterwards. Hackers use a thermal camera and then scan the keyboard of your computer where you typed your pbadword.
Researchers at the University of California, Irvine UCI, discovered that key presses could be recovered in half a minute The first touch was pressed with the help of commercially available solutions by FLIR cameras that detect infrared and heat. After one minute, thermal scans can be used to obtain partial pbadwords.
The researchers found that the thermal residue evaporates over time and that it is possible to recover thermal energy readings from a computer or laptop.
Thirty users who are not experts were asked to guess the pbadwords based on thermal imaging scans. Users were able to guess pbadwords within 19.5 and 31 seconds after their initial entry. While weak pbadwords like football took half a minute for non-experts, as reported by TechRepublic.
Thus, the researchers concluded that by using the indexes to type, a user can leave a larger footprint on each key. which led to more trace of heat left behind. This leads to the generation of more thermal noise. This made it difficult to badyze heat traces with the aid of the FLIR camera. While those who have acrylic nails are less prone to thermal attacks because they tap with the nails and therefore they leave almost no trace of heat behind.
Thus, the results suggest that thermal imaging attacks are realistic. If you need to keep your pbadwords safe when using computers in a public environment, you must use two-factor authentication. For this attack, an attacker must place a camera that has thermal recording characteristics near the computer from where he intends to steal the pbadwords. In addition, the research team believes that to get rid of pbadwords in order to secure user information, one needs an alternative to the use of pbadwords.
Researchers say
"As niche detectors become cheaper, new side attacks move from" Mission: Impossible "to reality, particularly true given the constant cost decrease and increasing availability of high quality thermal imagers. "
