ios-security-auditor

ios-security-auditor is a cursor rule for Cursor from gygantskiyMatilyock/ios-developer-agents. It costs 0 tokens per session (419 once invoked), scanned A, original, MIT.

A security review checklist for iOS applications based on the OWASP Mobile Top 10 from 2024. It focuses on risks such as exposed secrets, unsafe data storage, weak network settings, and authentication problems.

In plain words
What is it for?
Use it to audit iOS source code and configuration for hardcoded keys, unsafe UserDefaults or file storage, missing Keychain protection, permissive TLS settings, and insecure authentication handling.
Why use it?
It helps find common ways an iOS app could expose credentials or sensitive user data. The checklist gives concrete items to inspect instead of relying on a general security review.

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

ios-security-auditor 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 9d ago.

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.

What it actually says

iOS Security Auditor

When working with iOS code, check for OWASP Mobile Top 10 2024 vulnerabilities.

Data Storage (M9)

Flag insecure storage:

  • Sensitive data in UserDefaults (tokens, passwords, PII, API keys)
  • Sensitive data in plist files or bundle resources
  • Missing Keychain usage for credentials
  • Incorrect kSecAttrAccessible flags (avoid kSecAttrAccessibleAlways)
  • Unprotected files in Documents/tmp without .fileProtection
  • Unencrypted Core Data stores with sensitive data

Hardcoded Secrets (M1)

Scan for exposed credentials:

  • API keys hardcoded in source
  • Client secrets, tokens, passwords in code
  • Private keys or certificates in bundle
  • Database connection strings
  • Secrets in Info.plist or xcconfig files
  • Test credentials persisting to release builds

Network Security (M5)

Check network configuration:

  • NSAllowsArbitraryLoads disabled (ATS enabled)
  • No overly permissive exception domains
  • TLS 1.2+ enforcement
  • No ServerTrustPolicy.disableEvaluation
  • No allowsInvalidSSLCertificate flags
  • Sensitive data not in URL query parameters

Authentication (M3)

Review auth implementation:

  • Token storage uses Keychain
  • Server-side authorization for protected resources
  • Session invalidation on logout
  • No client-side only auth checks

Input Validation (M4)

Check for injection vulnerabilities:

  • Core Data predicates using parameterized queries
  • WKWebView evaluateJavaScript sanitizes input
  • URL scheme handlers validate parameters
  • File operations validate paths (no ../ traversal)

Output

Flag issues by severity:

  • CRITICAL: Immediate fix required (cite OWASP Mxx)
  • HIGH/MEDIUM/LOW: With remediation steps

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.
