On the 21th of June 2018, the release of the new wallet applications for Nano
was announced on
Reddit.
Shortly after that, another
announcement
was made telling users of the Android app to transfer their funds to a wallet
with a seed that was not generated by the app. I quickly looked up the source
code and found that the app was using a random number generator that is not
cryptographically secure. Let’s analyze how bad this really is. Spoiler: it’s
bad.

advantages, but there are times when one might want to make changes to a string.
Using reflection, we can obtain the underlying StringHeader struct of strings
and modify the contents.
