i always worry about tools like this, maintained by small teams, that are so universal that even if only a small fraction of installs are somehow co-opted by malicious actors, you have a wide open attack surface on most tech companies. e.g. iTerm, Cyberduck, editors of all shades, various VSCode extensions, etc.

Similarly I worry about how these apps automatically update themselves. I know it can be done securely. I also doubt that these companies invest the engineering effort to do so.

If you think large companies are somehow immune to this, you’re gonna have a bad time.

This all fascinating, but in the end: I have notepad++; what should I do?

You’d be protected from this particular exploit if you used a package manager rather than the updater, though of course you’d still be vulnerable to the installer binary itself getting compromised.

I'm extremely wary about any application pushing politics.

I subscribe to MacPaw, who makes excellent apps like Setapp, Gemini, and CleanMyMac, all of which I use.

At some point, CleanMyMac started putting the Ukranian flag on the app icon and flagging utilities by any Russian developer as untrustworthy (because they are russian), and recommended that I uninstall them.

I am not pro russia/anti-ukraine independence by any means, but CleanMyMac is one of those apps that require elevated system permissions. Seeing them engage in software maccarythism makes me very, very hesitant to provide them.

So the hosting provider was hacked? Who was their hosting provider? This is also why update signatures should be validated against a different server; it would require hackers to control bother servers to go undetected

No, it should be a hardcoded key held by the developer, preferably using a HSM, and maybe with some sort of notification capability in case the key was lost. Adding a second server adds marginal security. For instance if the developer's mail was hacked, an attacker would likely be able to reset passwords for both hosting providers.
