You can't trust anything. But you can trust Linux more than Windows since the internals are open source. So a heavy malware will be harder to hide in Linux compared to Windows. But anything is possible. Someone even mentioned injectable firmware to invade computers at the processor level.

No need for that, most modern processors already have nice, convenient side-channels for the crackers to use.

Works in both Windows and GNU/Linux as well, which is nice.

?

Which side channels are you talking about?

The ones used for remote access, maybe ,
most modern processors already have nice, convenient side-channels for the crackers to use
Lot's of interesting info , from 1 result:
https://www.usenix.org/system/files/con ... -masti.pdf
Side channels remain a challenge to information flow
control and security in modern computing platforms. Re-
source partitioning techniques that minimise the number
of shared resources among processes are often used to
address this challenge. In this work, we focus on multi-
core platforms and we demonstrate that even seemingly
strong isolation techniques based on dedicated cores can
be circumvented through the use of thermal channels.
Specifically, we show that the processor core tempera-
ture can be used both as a side channel as well as a
covert communication channel even when the system im-
plements strong spatial and temporal partitioning. Our
experiments on an Intel Xeon server platform demon-
strate covert thermal channels that achieve up to 12.5 bps
and weak thermal side channels that can detect processes
executed on neighbouring cores. This work therefore
shows a limitation in the isolation that can be achieved
on existing multi-core systems.
From another, but I will let the OP do their own searching, if they want to find where,and more details:

Ah ok it is related to the timing attack first referred to as Spectre and Meltdown. And they say CPUs need a new architecture design.

I thought it was something else.

Here is another thing. Using more that just software, it is possible to use electromagnetic measurements to hack a CPU. Like reading the "mind" of the computer using probabilistic guesses.

There are *many* potential side-channels and more are added with each new processor, the developers just can't help themselves... :roll:

Dunno about side-channels, but the real issue id ring0 CORES hidden in modern chips. Can network with system 'off'.

As for banking, 95% of boogerware is designed specifically to grab the info - usually with screen captures and keyloggers.
