re-ios-jb

re-ios-jb is a skill for Claude Code from dslsdzc/rev-skills. It costs 57 tokens per session (3,708 once invoked), scanned B, original, Apache-2.0.

A guide to analyzing iOS apps and tweaks in a jailbroken, controlled test environment, including jailbreak detection and runtime hooks.

In plain words
What is it for?
Use it to study jailbreak checks, inspect tweak plugins, develop Theos or Logos tweaks, and prepare an iOS device for Frida or LLDB analysis.
Why use it?
It provides the device access needed to observe protected app behavior and investigate why an app reacts to a jailbreak. It also separates static examination from risky live testing.

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 B, and why

re-ios-jb scanned grade B with 2 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.

iOS 越狱逆向环境(越狱检测 / tweak)

何时使用 / 何时不用

  • 用:目标 App 有越狱检测(启动闪退 / 功能受限),需要识别检测点并分析其实现
  • 用:已有 tweak / Substrate 插件需要逆向分析其 hook 了什么
  • 用:要在越狱设备上做动态分析([[re-frida]] 插桩、[[re-lldb]] 远程 attach)——越狱环境是前置
  • 用:自己开发 tweak(Theos + Logos)辅助逆向(hook 检测函数验证假设)
  • 不用:无越狱设备时的 iOS 动态分析(静态先行,见 [[re-ios]] 坑 3)
  • 不用:只要 App 静态结构 / 脱壳(走 [[re-ios]])
  • 注意:越狱与动态执行按 [[platform-tips]] 最高原则在受控设备上进行(专用测试设备,不用于日常/生产设备)

工具准备

越狱/动态分析属动态执行,受控设备 + 网络隔离([[platform-tips]] 最高原则)。静态(tweak 二进制分析)免沙箱。所有工具先验证再使用。

越狱设备(palera1n 等)

  • palera1n 无发行版包,官方安装途径(docs.palera.in):
    # 官方一键脚本(推荐)
    sudo /bin/sh -c "$(curl -fsSL https://static.palera.in/scripts/install.sh)"
    # 或 GitHub releases(palera1n/palera1n)手动下载二进制
    curl -LO https://github.com/palera1n/palera1n/releases/download/v2.0.2/palera1n-linux-x86_64
    chmod +x palera1n-linux-x86_64 && sudo mv palera1n-linux-x86_64 /usr/bin/palera1n
    
  • 限制:仅支持 checkm8 漏洞设备(A8–A11)及其支持的 iOS 版本(版本匹配见坑 2);在虚拟机里跑会段错误(无 PCI 透传不可用)
  • 验证: palera1n --help;越狱后设备上出现 Sileo(rootless 包管理器)
  • 越狱后安装 OpenSSH:Sileo 搜索 "openssh" 安装

Theos —— tweak 构建工具链(官方 git 安装,无发行版包)

  • 官方安装(theos.dev/docs/installation必须 git 安装,官方明确不要下载 ZIP):
    export THEOS=~/theos
    git clone --recursive https://github.com/theos/theos.git $THEOS
    echo "export THEOS=~/theos" >> ~/.zprofile && echo "export PATH=$THEOS/bin:$PATH" >> ~/.zprofile
    
  • 依赖:macOS brew install ldid xz;Linux 需 sudo apt install dpkg-dev fakeroot(Debian/Ubuntu)等打包依赖
  • iOS SDK:curl -LO https://github.com/theos/sdks/archive/master.zip 解出 *.sdk$THEOS/sdks
  • 更新: $THEOS/bin/update-theos(滚动发布)
  • 验证: $THEOS/bin/nic.pl 能列出 New Instance Creator 模板

frida([[re-frida]])—— 插桩与绕过执行

  • 越狱设备:Sileo/Cydia 添加源 https://build.frida.re 安装 frida;或 ssh root@<设备IP> 后安装
  • 主机:pip install frida-tools
  • 验证: frida-ps -U 列出设备进程

lldb 远程([[re-lldb]])+ usbmuxd/iproxy

  • lldb:macOS xcode-select --install(自带);Linux apt install lldb / dnf install lldb / pacman -S lldb
  • usbmuxd/iproxy:macOS brew install usbmuxd;Linux 的 iproxy 在 libimobiledevice-utils 包(Debian/Ubuntu/Fedora)/libimobiledevice 包(Arch),仅装 usbmuxd 不含 iproxy:apt install usbmuxd libimobiledevice-utils / dnf install usbmuxd libimobiledevice-utils / pacman -S usbmuxd libimobiledevice
  • 验证: lldb --versioniproxy 2222 22ssh -p 2222 [email protected] 能登录设备
  • 设备端调试服务 debugserver:越狱工具 / DeveloperDiskImage 提供(见 [[re-ios]] 与 [[re-lldb]])

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.

re-ios-jb is a skill published in the GitHub repository dslsdzc/rev-skills (54 stars, last pushed 14d ago), licensed Apache-2.0. It adds 57 tokens to every session and 3,708 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
