If you’re one of the people who own a stylus or touchscreen-capable Windows PC, then there’s a high chance there’s a file on your computer that has slowly collected sensitive data for the past months or even years.

This file is named WaitList.dat, and according to Digital Forensics and Incident Response (DFIR) expert Barnaby Skeggs, this file is only found on touchscreen-capable Windows PCs where the user has enabled the handwriting recognition feature [1, 2] that automatically translates stylus/touchscreen scribbles into formatted text.
