A procedure for examining Android app package files (APK files) without running them, using tools that unpack resources, recover Java code, and inspect app metadata and code.

In plain words
What is it for?
It is for analyzing Android malware samples, investigating security incidents, creating detection rules, and checking whether monitoring covers related threats.
Why use it?
It helps investigators spot suspicious permissions, hidden or obfuscated code, automatic code loading, and risky API use without executing the malware.

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

analyzing-android-malware-with-apktool 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/agent.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Analyzing Android Malware with Apktool

Overview

Android malware distributed as APK files can be statically analyzed to extract permissions, activities, services, broadcast receivers, and suspicious API calls without executing the sample. This skill uses androguard for programmatic APK analysis, identifying dangerous permission combinations, obfuscated code patterns, dynamic code loading, reflection-based API calls, and network communication indicators.

When to Use

  • When investigating security incidents that require analyzing android malware with apktool
  • When building detection rules or threat hunting queries for this domain
  • When SOC analysts need structured procedures for this analysis type
  • When validating security monitoring coverage for related attack techniques

Prerequisites

  • Python 3.9+ with androguard
  • apktool (for resource decompilation)
  • jadx (for Java source recovery, optional)
  • Isolated analysis environment (VM or sandbox)
  • Sample APK files for analysis

Steps

  1. Parse APK with androguard to extract manifest metadata
  2. Enumerate requested permissions and flag dangerous combinations
  3. List activities, services, receivers, and providers from manifest
  4. Scan for suspicious API calls (reflection, crypto, SMS, telephony)
  5. Detect dynamic code loading patterns (DexClassLoader, Runtime.exec)
  6. Extract hardcoded URLs, IPs, and C2 indicators from strings
  7. Generate risk assessment report with MITRE ATT&CK mobile mappings

Expected Output

  • JSON report with permission analysis, component listing, suspicious API calls, network indicators, and risk score
  • Extracted strings and potential IOCs from the APK
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
