of course it is possible to have safe memory coding.
when you use POKE, OUT you need to take care that you ensure the address is correct. that is relatively simple.
when you have the concept of pointers, and pointers to pointers it is more easy to have a buffer/memory overrun.
especial when you have no error checking or not enough error checking.
but even with safe code like
dim b as byte
b=10
and somewhere else you also write to b because of a logic or coding error, the variable is overwritten. of course this fault can not be exploited. code injection is often used to abuse flaws.
of course the list is about C/C++. all OS like windows, linux, are written in C/C++ and partial asm. and thus there are many potential flaws. in a normal good world that would not matter much. but in reality the world is not good everywhere especial when they have a dictator in control.
(state) hackers try to find these leaks to exploit them for good or worse.
why some countries have a connection to the internet is curious to me. i would shut down countries that have high hack attempts. the government of each country should make sure that there are no cross border attacks.
The dependency nowadays of the internet is worrying. a net not build for this purpose with lot of crappy IP hardware/software is asking for problems. but people are ignorant until it is too late.
so do not worry to much about these C memory coding flaws. better check how dependent you are on IP and how your provider handles things.
The cloud is also something to avoid. if you use it, make sure to have multiple clouds and spread risks.
And encode all data so it can not be read by governments. seems everywhere around the world the government like to read a long. and besides that Micro$oft , Google and the like also like to read so they can sell more advertisements.
if you want to make rock solid code you need many error checks. and then again, when it runs on an OS you must hope that it was created with rock solid code as well.
