The attackers pull the key from live process, not from disc so neither chmod nor disc defences method will work. The right fix is to keep the keys out of the runtime! Entirely!

It’s even mentioning they are detecting the agent framework so it’s easy to hide the malware inside its config/work directory. It’s clear, the best way to mitigate that is to start using per project scoped sandboxes.

Egress was the channel (DNS/OAST callbacks) so the network limitations beats the app layer boundaries.
