Just like most of you, I too really hate filling out web forms, especially on mobile devices.
To help make this whole process faster, Google Chrome and other major browsers offer “Autofill” feature that automatically fills out web form based on data you have previously entered in similar fields.
However, it turns out that an attacker can use this autofill feature against you and trick you into spilling your private information to hackers or malicious third parties.
Finnish web developer and whitehat hacker Viljami Kuosmanen published a demo on GitHub that shows how an attacker could take advantage of the autofill feature provided by most browsers, plugins, and tools such as Password Managers.
Although, this trick was first discovered by Ricardo Martin Rodriguez, Security Analyst at ElevenPaths, in the year 2013, but it seems Google haven’t done anything to address weakness in Autofill feature.
