See the accompanying Blog Post for a fun rant and some cool demos!
A SOCKS proxy written in Python that randomizes your source IP address. Round-robin your evil packets through SSH tunnels or give them billions of unique source addresses!
TREVORproxy IPv6 Subnet Proxy Diagram
- WAF bypass
- Password spraying
- Web scraping
TREVORproxy has two modes of operation: a Subnet Proxy and an SSH Proxy:
- Subnet Proxy mode uses the AnyIP feature of the Linux kernel to assign an entire subnet to your network interface, and give every connection a random source IP address from that subnet.
- E.g. if your cloud provider gives you a
/64
IPv6 range, you can send your traffic from over eighteen quintillion (18,446,744,073,709,551,616) unique IP addresses.
- E.g. if your cloud provider gives you a
- SSH Proxy mode combines
iptables
with SSH's SOCKS proxy feature (ssh -D
) to round-robin packets through remote systems (cloud VMs, etc.)
NOTE: TREVORproxy is not intended as a DoS tool, as it does not "spoof" packets. It is a fully-functioning SOCKS proxy, meaning that it is designed to accept return traffic.
- NOTE: In
subnet
mode,trevorproxy
must be run as root - NOTE: This must be a legitimate subnet, e.g. an IPv6 range allocated to you by your cloud provider.
