Hello! I think it is a nice time to re-mention some 101 tips of IT security for folks here, that I also practice. Pegasus malware investigation will be big news for a good while, so the more awareness it helps spread, the better.
RULE 1
DO NOT CLICK ON RANDOM SMS AND EMAIL LINKS. Please, do not do this, ever. Just do not do it. Do not do it. Do not do it. Do not do it.
Yes, that is how many times I repeated that line. That is how important this rule is.
Also, do not download random email attachments.
Phishing is such a common tactic that one would think this problem has been solved by now, but it has not.
RULE 2
Keep OFF auto download of photos, videos, documents and so on on WhatsApp, Signal and such apps.
Drive by downloads being self executable surprise bombs is not a new thing. Basically, this rule is similar to keeping off AutoPlay for external USB sticks on Windows computers.
RULE 3
Avoid using popular software too much.
I get it, this is a hard rule to workaround considering how much we need to use WhatsApp, Signal, Telegram and so on, so it is a lot better to compartmentalise your activities among multiple messengers.
Pegasus and a lot of specialised malware uses zero-days to be able to design zero click deployment tricks, which is what these government surveillance tools are good at reserving. They use their millions of dollars of funding and R&D properly, so you have to be careful.
As an example, try to keep WhatsApp internet turned off most of the times via NetGuard, and turn it on only when needed, a good method I have earlier suggested as well in my smartphone hardening guide.
CONCLUSION
Those were some thoughts on the top of my head, before I go to sleep. Stay safe against surveillance! And feel free to ask whatever you want to!
The most you can do against the unknown threat is take a whitelisting approach in life, unless you have a crystal ball that shows future. And that is how I laid out the rules. Not clicking random links, not downloading random files and not using common software is as far as you can go, and only the last one is considerably hard.
