apk-redteam-pipeline
End-to-end Android APK red-team pipeline — automated APK acquisition (Play Store + apkpure + apkmirror fallback), jadx decompilation, secret/URL/JWT/Firebase grep, pinned-cert extraction, exported-component enumeration, Frida runtime instrumentation templates, intent-injection probes. Built from an authorized external red-team engagement where 7 APKs were pulled manually, 4 download attempts truncated, and a hardcoded JWT + 30 internal API endpoints were recovered from one of the apps. Use when target has a mobile app catalogue (Play Store developer page), when you find an APK URL hosted on a web server, or when post-recon mentions "mobile app" in scope.

3 findings: 2 critical severity, 1 high severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
Several URLs point to third-party APK distribution endpoints and cloud storage (APKPure direct download, APKMirror/APKPure search, and Firebase Storage) which are commonly used to host unsigned or tampered APKs and thus represent a plausible malware-distribution vector.
E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
The document contains explicit, actionable instructions and scripts to discover and extract credentials/tokens, bypass certificate pinning, intercept API traffic (mitmproxy + Frida), and test/use leaked credentials against cloud APIs — capabilities that enable credential theft, data exfiltration, and remote access abuse.
W007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
This skill explicitly instructs the agent to grep/cat/decode APK artifacts and runtime traffic (google-services.json, strings, regexes for AKIA/AIza/sk- etc., Frida hooks that log headers) which will expose API keys, tokens and passwords verbatim — requiring the LLM to handle/output secrets directly.
