About Joro

Joro brings together the tools needed throughout a modern web application engagement into a single binary with an embedded web UI, reducing the need to switch between disconnected tools.

Instead of focusing only on web interception, Joro supports the entire engagement lifecycle:

  • Discover vulnerabilities through an intercepting proxy, fuzzing, and blind detection
  • Validate findings with replay, manipulation, and exploitation workflows
  • Execute through web shells and native Sliver C2 integration
  • Collaborate with shared notes, chat, and engagement tracking
  • Extend functionality with a Go plugin framework

Why Joro?

Most intercepting proxies excel at finding web vulnerabilities.

Modern offensive security engagements require much more than that.

Once an initial vulnerability is discovered, practitioners often need to:

  • Generate or deploy a web shell
  • Execute commands
  • Pivot into post-exploitation
  • Connect to a C2 framework
  • Document findings and collaborate with teammates

Traditional proxies typically rely on plugins or entirely separate tools for these workflows, forcing constant context switching.

Joro was built differently. Instead of stopping at web interception, Joro combines the capabilities needed throughout an engagement into a single platform.
