Performing Web Cache Deception Attack

Overview

Cybersecurity skill for performing web cache deception attack. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "performing web cache deception attack"

• "Execute web cache deception attacks by exploiting path normalization discrepanci"

• When testing applications behind CDNs or reverse proxies (Cloudflare, Akamai, Varnish, Nginx)

• During assessment of authenticated page caching behavior

• When evaluating path normalization differences between caching and origin layers

• During bug bounty hunting on applications with aggressive caching policies

• When testing for sensitive data exposure through cache layer misconfiguration

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

Prerequisites

• Understanding of HTTP caching mechanisms (Cache-Control, Vary, Age headers)
• Knowledge of CDN path normalization and cache key construction
• Burp Suite for intercepting and crafting requests
• Two browser sessions (authenticated victim and unauthenticated attacker)
• Understanding of URL path parsing differences across technologies
• Familiarity with common CDN platforms (Cloudflare, Akamai, Fastly, AWS CloudFront)

Legal Notice: This skill is for authorized security testing and educational purposes only. Unauthorized use against systems you do not own or have written permission to test is illegal and may violate computer fraud laws.

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs() -> :
     {k: re.findall(v, text)  k, v  IOC_PATTERNS.items()}
