Tl;dr: A Bitcoin investor was recently scammed out of 9 Bitcoin (worth around $490K) in a fake “Exodus wallet” desktop application for Linux, published in the Canonical Snap Store. This isn’t the first time, and if nothing changes, it likely won’t be the last.
This post turned out longer than I expected. So if you don’t have the time there’s a briefer summary at the bottom under “In summary (the tl;dr)” along with my suggestions on what Canonical should do now.
