Probably not. But FreeDOS lives on. Modern toolchains can compile to FreeDOS executables. FreeDOS is useful when you want a computer to run one program and nothing else. You can be confident that there's no backdoor network connection because there's no networking support in the OS.

I wonder how feasible it would be for malware to inject networking support into FreeDOS? Drivers, a TCP/IP stack, not very familiar with how DOS is constructed compared to my studies on the modern Linux kernel.

I would think the hardest part would be knowing what NIC to target, otherwise it's just a matter of work.

It's trivial. There's an opensource tcp/ip stack for dos. I used to use it back in 98 to connect to the internet with my 386sx

The lack of network support and thus no backdoor is one of the reasons I love SQLite.
