Device mesh (Androids/Chromes) to share suspicious behavior
The proposal is to use the consensus between devices on genuine and suspect characteristics
A device should be able to query from a safe and reliable source if another device has performed (within a defined period of time) some malicious action similar to the one it is going to perform, so it could make the decision not to perform that same action, autonomously.
…just in case you wanted to install an ad blocker malicious software, or something.
