A major vulnerability that potentially allows third parties unrestricted access to your passwords has been found in 3M Post-it Notes. Passwords stored in Post-it Notes have been discovered to be stored in plain text, very often in biro. A malicious individual, if they gained access to your desktop, could easily read these passwords from Post-it Notes.

Post-It Notes have been one of the most popular password storage solutions in the world for over 20 years and is used daily by an estimated 350 million users worldwide, mostly in government offices. This security flaw is likely to affected 100% of users and no workaround or patch has so far been found to adequately fix the hole.

3M have been advised of this flaw but have yet to comment…
