A few months ago I stumbled upon a 2016 blog post by Mark Murphy, warning about the state of FLAG_SECURE window leaks in Android. This class of vulnerabilities has been around for a while, hence I wasn’t confident that I could still leverage the same weakness in modern Android applications. As it often turns out, I was being too optimistic. After a brief survey, I discovered that the issue still persists today in many password manager applications (and others).
