apk-redteam-pipeline

The apk-redteam-pipeline automates Android APK acquisition from public mirrors (Play Store, APKPure, APKMirror), decompilation via Jadx, and extraction of secrets, hardcoded credentials, Firebase configs, pinned certificates, exported components, and runtime instrumentation hooks. Use this when the target maintains a mobile app catalog, APK files are hosted on web servers, or APK package IDs appear in reconnaissance data and Android is explicitly in scope.

## When to use this skill

Trigger when:
- Recon surfaces 1+ mobile apps under the target's developer name (Play Store dev page)
- A web app hosts `*.apk` files directly (e.g. `Recruitz.apk` found on a subdomain during one engagement)
- APK package IDs leaked via stealer logs (e.g. `com.<brand>.app`, `com.<brand>.<sub-brand>` patterns in stealer dump format)
- Customer-facing app, dealer/partner portal, or employee mobile companion app is in scope
- Bug bounty program lists Android in scope

DO NOT use for:
- iOS-only targets (different pipeline — IPA reverse, MobSF, frida-ios-dump)
- React Native / Flutter web apps already covered by JS bundle analysis
- Server-side only assessments

---

## Stage 0 — Inventory all org-owned apps

### Play Store developer-page scrape
```bash
# Find developer page from the target's brand name
curl -sk -A "Mozilla/5.0" "https://play.google.com/store/apps/developer?id=<Brand+Name>" -o /tmp/dev.html

# Extract package IDs
grep -oE 'id=[a-zA-Z0-9._]+' /tmp/dev.html | sort -u
```

Example output (anonymized — 7 packages typical for a multi-brand conglomerate):
```
com.events.<brand>build
com.<corp>.<sub-brand-1>
com.<corp>.<sub-brand-2>
com.<corp>.<flagship>
com.<corp>.<product-line-1>
com.<corp>.<product-line-2>
com.<corp>.<sub-brand-3>
```

### Cross-reference with stealer logs
Stealer-log format includes package names like `*@com.<corp>.<app>` — extract these from `creds_userpass.txt` if you have a leaked dump.

### Brand permutation guesses (multi-brand conglomerate patterns)
```
com.<brand>.app
com.<brand>.mobile  
com.<brand>.android
com.<brand>connect.app
in.<brand>.dealer
in.co.<brand>.app
```

---

## Stage 1 — APK acquisition

### Primary: APKPure direct (no auth required)
```bash
# Follow 302 redirects to actual download
curl -sk -L --max-time 60 \
  "https://d.apkpure.net/b/APK/<package_id>?version=latest" \
  -o "<package_id>.apk"

# Or via the legacy d-XX.winudf.com mirror chain (we saw this work)
```

### Secondary: APKMirror search
```bash
curl -sk -A "Mozilla/5.0" "https://www.apkmirror.com/?post_type=app_release&searchtype=apk&s=<brand>" \
  | grep -oE 'href="[^"]+\.apk[^"]*"' | sort -u
```

### Tertiary: APKPure web search
```bash
curl -sk "https://apkpure.com/search?q=<brand>" | grep -oE 'data-dt-app="[^"]+"'
```

### XAPK vs APK
- `.xapk` = a zip containing multiple split APKs (base + config.armeabi-v7a + config.en + etc.)
- Unzip outer first, then unzip the inner `base.apk` or `<package>.apk`
- Some apkpure downloads return truncated XAPK with missing EOCD signature — symptom of CDN rate-limiting; rotate IP and retry, OR use `7z x` which is more lenient than `unzip`

```bash
# Standard unzip (works for clean APK)
unzip -o <package>.apk -d extracted_<package>/

# For truncated/repaired XAPK
7z x -y <package>.apk -o"extracted_<package>"

# For nested XAPK
for inner in extracted_<package>/*.apk; do
  mkdir -p "extracted_<package>/$(basename "$inner" .apk)"
  unzip -o "$inner" -d "extracted_<package>/$(basename "$inner" .apk)"
done
```

---

## Stage 2 — DEX decompilation (jadx)

```bash
# Install
brew install jadx          # macOS
# or
wget https://github.com/skylot/jadx/releases/latest/download/jadx-1.5.x.zip

# Decompile
jadx -d decompiled_<package>/ <package>.apk

# For XAPK that contains multiple APKs
for inner in extracted_<package>/*.apk; do
  jadx -d decompiled_<package>_$(basename "$inner" .apk)/ "$inner"
done
```

For a fast "strings only" pass without full decompilation:
```bash
find extracted_<package> -name "classes*.dex" -exec strings -8 {} \; > strings_<package>.txt
```

---

## Stage 3 — Secret grep (the 60-pattern catalog)

```bash
# URL grep — owned-domain references
grep -oE 'https?://[a-zA-Z0-9.-]+\.(target1|target2|target3)\.(com|io|net|in)[a-zA-Z0-9./_?=&%-]*' strings_<package>.txt | sort -u

# Internal IP / port URLs
grep -oE 'https?://(10\.|172\.(1[6-9]|2[0-9]|3[01])\.|192\.168\.|127\.)[0-9.]+(:[0-9]+)?[a-zA-Z0-9./_?=&-]*' strings_<package>.txt

# Cloud credentials
grep -oE 'AKIA[A-Z0-9]{16}'                            # AWS Access Key
grep -oE 'aws_secret_access_key[\s:=]+[A-Za-z0-9/+=]{40}' # AWS Secret
grep -oE 'AIza[A-Za-z0-9_-]{35}'                       # Google API key

grep -oE 'glpat-[A-Za-z0-9_-]{20}'                     # GitLab PAT
grep -oE 'xox[pbar]-[A-Za-z0-9-]+'                     # Slack token
grep -oE 'sk-[A-Za-z0-9]{48}'                          # OpenAI API key
grep -oE 'sk-ant-[A-Za-z0-9_-]{90,}'                   # Anthropic API key
grep -oE 'AC[a-f0-9]{32}'                              # Twilio Account SID
grep -oE 'sk_live_[A-Za-z0-9]{24}'                     # Stripe live key
grep -oE 'pk_live_[A-Za-z0-9]{24}'                     # Stripe publishable
grep -oE 'mailgun-[A-Za-z0-9-]{40}'                    # Mailgun
grep -oE 'SG\.[A-Za-z0-9_-]{22}\.[A-Za-z0-9_-]{43}'    # SendGrid

# JWT (any algorithm)
grep -oE 'eyJ[A-Za-z0-9_-]+\.eyJ[A-Za-z0-9_-]+\.[A-Za-z0-9_-]*' strings_<package>.txt

# Firebase
grep -oE '"(api_key|project_id|database_url|storage_bucket|client_id|mobilesdk_app_id|google_app_id|gcm_defaultSenderId)"\s*:\s*"[^"]+"' \
  extracted_<package>/res/values/strings.xml \
  extracted_<package>/google-services.json \
  decompiled_<package>/resources/AndroidManifest.xml 2>/dev/null

# OAuth client secrets
grep -oE 'client_secret["\s:=]+[A-Za-z0-9_-]{24,}' strings_<package>.txt

# Hardcoded passwords (heuristic — many false positives, manual review)
grep -oE '"password"\s*:\s*"[^"]+"|password\s*=\s*"[^"]+"' decompiled_<package>/sources/**/*.java 2>/dev/null
```

### Real-world example finding (anonymized — from an authorized engagement)
```
# Customer-facing APK shipped a hardcoded URL of this shape:
https://api.<client>.example/<path-token>/<resource-token>?token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.<payload>.<sig>

# Decoded JWT payload
autopilotSlash Command

Run autonomous hunt loop on a target — scope check → recon → rank surface → hunt → validate → report with configurable checkpoints. Usage: /autopilot target.com [--paranoid|--normal|--yolo]

bb-local-toolkitSkill

Local-tooling companion to the bug-bounty orchestrator — carries the SAME complete bug-bounty workflow, but reach for THIS variant when you also need to resolve where tools, wordlists, and clones are installed on the local machine (jhaddix, SecLists, trufflehog, ffuf, dalfox, ghauri); for pure orchestration/routing use the bug-bounty skill. Workflow it covers — recon (subdomain enumeration, asset discovery, fingerprinting, HackerOne scope, source code audit), pre-hunt learning (disclosed reports, tech stack research, mind maps, threat modeling), vulnerability hunting (IDOR, SSRF, XSS, auth bypass, CSRF, race conditions, SQLi, XXE, file upload, business logic, GraphQL, HTTP smuggling, cache poisoning, OAuth, timing side-channels, OIDC, SSTI, subdomain takeover, cloud misconfig, ATO chains, agentic AI), LLM/AI security testing (chatbot IDOR, prompt injection, indirect injection, ASCII smuggling, exfil channels, RCE via code tools, system prompt extraction, ASI01-ASI10), A-to-B bug chaining (IDOR→auth bypass, SSRF→cloud metadata, XSS→ATO, open redirect→OAuth theft, S3→bundle→secret→OAuth), bypass tables (SSRF IP bypass, open redirect bypass, file upload bypass), language-specific grep (JS prototype pollution, Python pickle, PHP type juggling, Go template.HTML, Ruby YAML.load, Rust unwrap), and reporting (7-Question Gate, 4 validation gates, human-tone writing, templates by vuln class, CVSS 3.1, PoC generation, always-rejected list, conditional chain table, submission checklist). Use when you need the local install path of a tool / wordlist / clone for a hunt, or as the full-workflow variant when operating from this local toolkit; for general routing use the bug-bounty skill. 中文触发词:漏洞赏金、安全测试、渗透测试、漏洞挖掘、信息收集、子域名枚举、XSS测试、SQL注入、SSRF、安全审计、漏洞报告

bb-methodologySkill

Use at the START of any bug bounty hunting session, when switching targets, or when feeling lost about what to do next. Master orchestrator that combines the 5-phase non-linear hunting workflow with the critical thinking framework (developer psychology, anomaly detection, What-If experiments). Routes to all other skills based on current hunting phase. Also use when asking "what should I do next" or "where am I in the process.

bug-bountySkill

Complete bug bounty workflow — recon (subdomain enumeration, asset discovery, fingerprinting, HackerOne scope, source code audit), pre-hunt learning (disclosed reports, tech stack research, mind maps, threat modeling), vulnerability hunting (IDOR, SSRF, XSS, auth bypass, CSRF, race conditions, SQLi, XXE, file upload, business logic, GraphQL, HTTP smuggling, cache poisoning, OAuth, timing side-channels, OIDC, SSTI, subdomain takeover, cloud misconfig, ATO chains, agentic AI), LLM/AI security testing (chatbot IDOR, prompt injection, indirect injection, ASCII smuggling, exfil channels, RCE via code tools, system prompt extraction, ASI01-ASI10), A-to-B bug chaining (IDOR→auth bypass, SSRF→cloud metadata, XSS→ATO, open redirect→OAuth theft, S3→bundle→secret→OAuth), bypass tables (SSRF IP bypass, open redirect bypass, file upload bypass), language-specific grep (JS prototype pollution, Python pickle, PHP type juggling, Go template.HTML, Ruby YAML.load, Rust unwrap), and reporting (7-Question Gate, 4 validation gates, human-tone writing, templates by vuln class, CVSS 3.1, PoC generation, always-rejected list, conditional chain table, submission checklist). Use for ANY bug bounty task — starting a new target, doing recon, hunting specific vulns, auditing source code, testing AI features, validating findings, or writing reports. 中文触发词:漏洞赏金、安全测试、渗透测试、漏洞挖掘、信息收集、子域名枚举、XSS测试、SQL注入、SSRF、安全审计、漏洞报告

bugcrowd-reportingSkill

Bugcrowd-specific reporting tactics complementing report-writing: VRT category search-and-fallback strategy when no exact match exists, manual severity override when VRT defaults underrate impact, severity-request paragraph as first body section, OOS-clause rebuttal templates (rate limiting on auth-flow endpoints, debug-info framing, user-enumeration with sensitive PII, theoretical-issue counter), chained-finding cross-reference patterns, target selection for QA-vs-prod programs, researcher-side hygiene (Bugcrowdninja email alias, account state restoration, friendly-tester posture). Use when filing a Bugcrowd submission, when VRT default seems wrong, when triager closes as OOS or downgrades severity, when chaining linked submissions, or when scope distinguishes production from QA. Pairs with report-writing and triage-validation.

chainSlash Command

Build an exploit chain — given bug A, finds B and C to combine for higher severity and payout. Knows common chain patterns: IDOR→ATO, SSRF→cloud metadata, XSS→ATO, open redirect→OAuth theft, S3→bundle→secret→OAuth. Usage: /chain

cloud-iam-deepSkill

Cloud IAM red-team attack chain across AWS, Azure, GCP — focused on EXTERNAL exploitation paths and post-credential-discovery privilege analysis. Covers IAM enumeration (aws iam, az role, gcloud iam), STS/AssumeRole chaining, Azure Managed Identity abuse (via SSRF/leak), GCP service account JSON abuse, IMDSv1/v2 attacks via SSRF, K8s ServiceAccount token privilege analysis once held (token discovery / cluster exposure is owned by hunt-k8s), role-trust-policy confused-deputy, cross-account assume-role enumeration, IAM privilege escalation patterns (24+ AWS, 8+ Azure, 6+ GCP), and AWS Cognito Identity Pool unauthenticated-role attack chain (GetId → GetCredentialsForIdentity → IAM role abuse). Built for the case where recon yields a credential (key, JSON, token) and you need to know what it grants and how to escalate. Use when an AWS key / Azure secret / GCP service account JSON / K8s SA token surfaces from a code repo, JS bundle, APK, breach corpus, or SSRF chain.

enterprise-vpn-attackSkill

External SSL VPN / remote-access appliance attack matrix — Cisco ASA/AnyConnect, Fortinet FortiGate/FortiOS, Citrix NetScaler/ADC, Palo Alto GlobalProtect, Pulse Secure / Ivanti Connect Secure, SonicWall, F5 Big-IP. Covers version fingerprinting, CVE matrix (2018-2026), AAA backend identification, default credentials, configuration-disclosure paths, pre-auth RCE/SSRF/path-traversal exploits where applicable. Built from authorized-engagement Cisco ASA testing plus 2024-2026 enterprise VPN CVE landscape. Use whenever the target's perimeter exposes any SSL VPN appliance or remote-access gateway — these are the most common initial-access points in 2024-2026 actor TTPs.
