Not necessarily.

If you read anything, at least read this link to self correct.

This is a common area where non-security professionals out themselves as not actually being such: The broken/fallacy reasoning about security risk management. Generally the same "Dismissive security by way of ignorance" premises.

It's fundamentally the same as "safety" (Think OSHA and CSB) The same thought processes, the same risk models, the same risk factors....etc

And similarly the same negligence towards filling in holes in your "swiss cheese model".

"Oh that can't happen because that would mean x,y,z would have to happen and those are even worse"

"Oh that's not possible because A happening means C would have to happen first, so we don't need to consider this is a risk"

....etc

The same logic you're using is the same logic that the industry has decades of evidence showing how wrong it is.

Decades of evidence indicating that you are wrong, you know infinitely less than you think you do, and you most definitely are not capable of exhaustively enumerating all influencing factors. No one is. It's beyond arrogant for anyone to think that they could 🤦🤦 🤦

Thus, most risks are considered valid risks (this doesn't necessarily mean they are all mitigatable though). Each risk is a hole in your model. And each hole is in itself at a unique risk of lining up with other holes, and developing into an actual safety or security incident.

In this case

• signal was alerted to this over 6 years ago
• the framework they use for the desktop app already has built-in features for this problem.
  • this is a common problem with common solutions that are industry-wide.
• someone has already made a pull request to enable the electron safe storage API. And signal has ignored it.

Thus this is just straight up negligence on their part.

There's not really much in the way of good excuses here. We're talking about a run of the mill problem that has baked in solutions in most major frameworks including the one signal uses.
