A KeyLogger using eBPF written in Rust (github.com/pythops)
Capture keystrokes and store them in a queue in the kernel. Intercept DNS requests and inject the captured keystroes in the DNS payload then redirect the request designated remote server acting as a DNS proxy. On the remote server, extract the keys from the DNS payload and send a valid DNS response. Intercept the response and modify its source address so the initial request will complete successfully.
