    Local protocol for safe agentic AI. Intent + impact + verifiable

    PIC (Provenance & Intent Contracts) serves as an action firewall for agentic AI. Lightweight, it adds machine-verifiable contracts to agent calls and actions and it is particularly efective at shielding the agent from propmpt-injection. Before any high-impact tool call, the agent must submit an Action Proposal (schema + verifier): - explicit intent - impact classification (read / write / money / irreversible / privacy / etc.) - provenance sources with trust levels (untrusted →...

    fancyss is a project for bypassing the Great Firewall (GFW)

    Fancyss is a “scientific Internet access / bypassing censorship” toolkit targeted principally to Asus routers running AsusWRT or Merlin-based firmware. The project provides a plugin suite (with “software center” integration) so that home routers can run proxy or tunneling tools (e.g. V2Ray) to circumvent firewall or censorship (“GFW” in the Chinese context). Because it integrates into the router’s firmware environment, fancyss automates configuration, routing, and firewall rules to minimize...

    Slipstream

    Slipstream

    NAT Slipstreaming allows an attacker to remotely access any TCP/UDP

    Slipstream (also referred to as “NAT Slipstreaming”) is a proof-of-concept exploit framework that allows an attacker to remotely access any TCP or UDP service running on a victim machine inside a NAT (behind a router/firewall) simply by tricking the target to visit a malicious website. It works by abusing the NAT’s Application Level Gateway (ALG) logic and connection tracking, combined with browser capabilities like WebRTC, precise packet fragmentation or boundary control, and packet injection techniques. The attack is able to bypass browser port restrictions by fragmenting or massaging packets so that the “exploit payload” lands in a packet boundary that gets parsed by the NAT/ALG as a legitimate protocol packet (e.g. ...

    Trojan-Go

    Trojan-Go

    A Trojan proxy written in Go

    In the early days, the firewall only intercepted and reviewed outbound traffic, that is,Passive detection. Shadowsoks' encryption protocol design makes the transmitted data package itself have almost no characteristics, and it looks similar to a completely random bitflow, which can indeed effectively bypass GFW in the early days. Contrary to Shadowsoks, Trojan does not use self-defined encryption protocols to hide itself.

It focuses on broad protection—SQL injection, cross-site scripting, local/remote file inclusion, command injection, and protocol violations—without requiring app-specific knowledge. Rules are organized into paranoia levels so operators can tune detection aggressiveness and balance false positives against coverage. ...
