Review the source first

Review the source first: our audit of ctf-web's source files found 14 shell commands, 7 external URLs, file reads and writes (high risk). Every command and URL listed appears verbatim in the skill's source. The skill instructs the agent to execute arbitrary shell commands and perform network requests against user-provided targets, which can lead to remote code execution or unauthorized network activity.

Frequently asked questions

What types of challenges is this skill designed for?

It targets web-heavy challenges involving HTTP applications, APIs, browser clients, template engines, and identity flows.

Does this skill handle binary exploitation?

No. The skill directs users to switch to other skills like /ctf-reverse or /ctf-pwn for native binary memory corruption or reverse engineering.

What tools must be installed to use this skill?

The skill requires sqlmap, flask-unsign, requests, hashcat, jq, curl, and ffuf.
