Performing iOS App Security Assessment is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. Performs comprehensive iOS application security assessments using Frida for dynamic instrumentation, Objection for runtime exploration, SSL pinning bypass for traffic interception, keychain extraction for credential analysis, and IPA static analysis for binary-level review. Use when conducting authorized iOS penetration tests, evaluating mobile app security posture against OWASP MASTG, or assessing iOS app data protection and transport security controls. Activates for requests involving iOS app pentesting…
Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts and reference files (for example `references/api-reference.md` and `scripts/agent.py`).
It sits in Security, covering iOS development, Mobile application security and Security review. It works with iOS and Frida. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.
7 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pipFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Performing iOS App Security Assessment loads about 3k tokens when it runs, and up to ~4k if it reads all its reference files. Until then it costs about 161 tokens; SKILL.md has 751 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

| Frida | Dynamic instrumentation toolkit that injects a JavaScript engine into target processes, enabling runtime hooking, tracing, and modification of iOS app behavior |
| Objection | Runtime mobile exploration toolkit built on Frida providing pre-built commands for common security tests including keychain dump, SSL pinning bypass, and method hooking |
| SSL Pinning | Client-side certificate validation that restricts which TLS certificates the app trusts, preventing proxy-based traffic interception; bypassed by hooking trust evaluation functions |
| Keychain | iOS secure storage API for credentials and tokens; items have accessibility attributes that control when they can be read (e.g., only when device is unlocked) |
| IPA | iOS App Store Package; a ZIP archive containing the app binary, frameworks, assets, and provisioning profile that can be extracted for static analysis |
| OWASP MASTG | Mobile Application Security Testing Guide; comprehensive methodology for iOS and Android security testing organized by MASVS verification categories |
| Frida Gadget | Shared library (.dylib) injected into IPA for non-jailbroken testing; enables Frida instrumentation without requiring a jailbroken device |
| Method Swizzling | Objective-C runtime technique that exchanges method implementations at runtime; used by Frida to intercept and modify method behavior |

**ID**: IOS-001
**Severity**: High (CVSS 7.5)
**OWASP MASTG**: MASTG-TEST-0055 (Testing Data Storage)
**MASVS Category**: MASVS-STORAGE
**Description**:
The application stores OAuth refresh tokens in the iOS Keychain with
the accessibility attribute kSecAttrAccessibleAlways, making them
readable even when the device is locked or after a reboot without
user authentication.
**Proof of Concept**:
1. Attach Objection to com.target.app: objection --gadget com.target.app explore
2. Execute: ios keychain dump
3. Observe refresh_token item with Accessible: kSecAttrAccessibleAlways
4. Token value is accessible without device unlock
**Impact**:
An attacker with physical access to a locked device or forensic
image can extract OAuth refresh tokens and gain persistent access
to the user's account without knowing device passcode.
**Remediation**:
Store sensitive credentials with kSecAttrAccessibleWhenUnlockedThisDeviceOnly
and enable biometric protection via kSecAccessControlBiometryCurrentSet.© mukul975, Apache-2.0. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file

Going by SKILL.md and its folder, Performing iOS App Security Assessment needs Python for the scripts in its folder and the command-line tools its instructions call (pip). Our summary lists: Python 3.
SKILL.md contains no URLs. Its commands use pip, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Performing iOS App Security Assessment is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 3k tokens (SKILL.md is roughly 12k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.1k tokens, read only when the agent opens those files.
