Coinomi wallet bug sends users' secret passphrases to Google's Spellcheck API via HTTP, in plaintext.
Cryptocurrency wallet caught sending user passwords to Google's spellchecker
[...] "To understand what's going on, I will explain it technically," Al Maawali said. "Coinomi core functionality is built using Java programming language. The user interface is designed using HTML/JavaScript and rendered using integrated Chromium (Google's open-source project) based browser."
Al Maawali says that just like any other Chromium-based app, it comes integrated with various Google-centered features, such as the automatic spellcheck feature for all user input text boxes.
The issue appears to be that the Coinomi team did not bother to disable this feature in their wallet's UI code, leading to a situation where all their users' passwords are leaking via HTTP during the setup process.

Smart man. I've been writing billing software since the 90s and will never, ever, under any circumstances, I really mean it, put anything but an anonymous, prepaid card across the Internet. I know exactly how hard it is to get precisely right and I have a good idea how many truly shitty programmers there are out there.
