# 📦 Installation Guide
|
||||
|
||||
## ⚡ Schnellstart (empfohlen)
|
||||
|
||||
```bash
|
||||
# 1. Source Tarball herunterladen (enthält ALLE Dateien)
|
||||
cd /tmp
|
||||
wget https://gitea.die-heimatlosen.eu/arch_agent/aegisaur/archive/master.tar.gz
|
||||
|
||||
# 2. Entpacken
|
||||
tar xzf master.tar.gz
|
||||
cd aegisaur
|
||||
|
||||
# 3. Verifizieren (alle 7 Dateien müssen da sein)
|
||||
ls src/
|
||||
# → config.rs, hook.rs, ioc_fetcher.rs, main.rs, scanner.rs, trust_scorer.rs, utils.rs
|
||||
|
||||
# 4. Bauen und installieren
|
||||
cargo build --release
|
||||
sudo cp target/release/aegisaur /usr/local/bin/
|
||||
sudo aegisaur install-hook
|
||||
```
|
||||
|
||||
## ⚠️ WICHTIG: Git-Clone NICHT verwenden!
|
||||
|
||||
```bash
|
||||
# ❌ NICHT SO - Fehlende Dateien!
|
||||
git clone https://gitea.die-heimatlosen.eu/arch_agent/aegisaur.git
|
||||
|
||||
# Warum: Gitea API zeigt Dateien >10KB nicht korrekt an
|
||||
# (ioc_fetcher.rs, scanner.rs, trust_scorer.rs fehlen)
|
||||
```
|
||||
|
||||
## Alternative: PKGBUILD
|
||||
|
||||
```bash
|
||||
cd /tmp/aegisaur
|
||||
makepkg -si
|
||||
```
|
||||
|
||||
## ALPM-Hook (systemweit)
|
||||
|
||||
```bash
|
||||
# Installiert Hook nach /usr/share/libalpm/hooks/
|
||||
sudo aegisaur install-hook
|
||||
|
||||
# Deinstalliert Hook
|
||||
sudo aegisaur remove-hook
|
||||
```
|
||||
|
||||
## Konfiguration
|
||||
|
||||
```bash
|
||||
# Erstellt ~/.config/aegisaur/config.toml
|
||||
aegisaur config
|
||||

# AegisAUR v2.1.0 👻
|
||||
|
||||
**Vollständiger AUR Security Scanner für Arch Linux**
|
||||
|
||||
Schutz gegen Supply-Chain-Angriffe, Malware und kompromittierte Pakete im AUR.
|
||||
|
||||
## ⚡ Schnellstart
|
||||
|
||||
```bash
|
||||
# Download (Tarball — Git-Clone hat bekannte Probleme mit großen Dateien)
|
||||
wget https://gitea.die-heimatlosen.eu/arch_agent/aegisaur/archive/v2.1.0.tar.gz
|
||||
tar xzf v2.1.0.tar.gz && cd aegisaur
|
||||
cargo build --release
|
||||
sudo cp target/release/aegisaur /usr/local/bin/
|
||||
sudo aegisaur install-hook
|
||||
sudo aegisaur install-timer
|
||||
```
|
||||
|
||||
## 🎯 Features v2.1.0
|
||||
|
||||
### Systemd Timer — Automatische Scans
|
||||
```bash
|
||||
sudo aegisaur install-timer # Tägliche Scans aktivieren
|
||||
sudo aegisaur remove-timer # Timer deaktivieren
|
||||
```
|
||||
- **Zeit:** Täglich um 03:00 Uhr (mit 1h RandomizedDelay)
|
||||
- **Logs:** `journalctl -u aegisaur-scan.service`
|
||||
- **Status:** `systemctl status aegisaur-scan.timer`
|
||||
|
||||
### Multi-Source Threat Intelligence
|
||||
- **HedgeDoc (Live)**: Sofort aktuell
|
||||
- **CISA KEV**: US Government Advisories
|
||||
- **Arch Security**: Offizielle Arch Linux Advisories
|
||||
- **Atomic Arch Gist**: Community-Listen
|
||||
|
||||
### Smartes Scoring
|
||||
- **AUR vs. Offizielles Repo**: Keine False-Positives für Repo-Pakete
|
||||
- **Trust-Scoring**: 0-100 mit 12 Heuristiken
|
||||
- **AUR-Info Score**: Votes, Popularität, Maintainer-Status
|
||||
- **Cache**: 5-Minuten-TTL für maximale Aktualität
|
||||
|
||||
### Cache-Status
|
||||
```bash
|
||||
aegisaur check-ioc
|
||||
🛡️ Prüfe IOC-Listen: all
|
||||
📦 1931 IOCs aus Cache (Alter: 2m 30s / TTL: 5m) ← Cache-Hit
|
||||
⚠️ Bedrohungen gefunden: 1
|
||||
🔴 gtkimageview - MaliciousBuildScript
|
||||
```
|
||||
|
||||
## 🚀 Befehle
|
||||
|
||||
```bash
|
||||
aegisaur scan <paket> # Einzelnes Paket (AUR-spezifisch)
|
||||
aegisaur scan-all # Alle AUR-Pakete (~30s für 125 Pakete)
|
||||
aegisaur check-ioc # IOC-Listen prüfen
|
||||
sudo aegisaur install-hook # ALPM-Hook installieren
|
||||
sudo aegisaur remove-hook # ALPM-Hook entfernen
|
||||
sudo aegisaur install-timer # Systemd-Timer installieren
|
||||
sudo aegisaur remove-timer # Systemd-Timer entfernen
|
||||
```
|
||||

# 📖 AegisAUR Usage Guide
|
||||
|
||||
## Befehls-Übersicht
|
||||
|
||||
```bash
|
||||
# Einzelnes Paket scannen
|
||||
aegisaur scan <paketname> [--verbose]
|
||||
|
||||
# Alle AUR-Pakete scannen
|
||||
aegisaur scan-all [--verbose]
|
||||
|
||||
# IOC-Check (wie aurvulntest)
|
||||
aegisaur check-ioc [--list atomicarch|all]
|
||||
|
||||
# Whitelist-Verwaltung
|
||||
aegisaur allow <paketname>
|
||||
aegisaur deny <paketname>
|
||||
|
||||
# System-Konfiguration
|
||||
aegisaur config
|
||||
aegisaur cache
|
||||
|
||||
# ALPM-Hook (root nötig)
|
||||
sudo aegisaur install-hook
|
||||
sudo aegisaur remove-hook
|
||||
```
|
||||
|
||||
## Beispiel-Workflows
|
||||
|
||||
### Vor Installation eines AUR-Pakets
|
||||
```bash
|
||||
# 1. Scannen
|
||||
aegisaur scan neues-paket
|
||||
|
||||
# 2. Wenn IOC erkannt → NICHT installieren
|
||||
# 3. Wenn verdächtig → PKGBUILD prüfen
|
||||
# 4. Wenn OK → installieren (mit Hook automatisch)
|
||||
|
||||
yay -S neues-paket # Hook scannt automatisch
|
||||
```
|
||||
|
||||
### Regelmäßige Checks
|
||||
```bash
|
||||
# Alle 48h (via cron/systemd)
|
||||
aegisaur check-ioc
|
||||
```
|
||||
|
||||
### Volle Systemprüfung
|
||||
```bash
|
||||
# Alle AUR-Pakete scannen + IOC-Listen checken
|
||||
aegisaur scan-all && aegisaur check-ioc
|
||||
```
|
||||
|
||||
## Exit Codes
|
||||
|
||||
| Code | Bedeutung |
|
||||
|------|-----------|
|
||||
| 0 | Erfolg |
|
||||
| 1 | Allgemeiner Fehler |
|
||||
| 2 | IOC erkannt / Kritisch |
|
||||
| 3 | Scan-Fehler |
|
||||
|
||||

### Hook funktioniert nicht
|
||||
```bash
|
||||
# Rechte prüfen
|
||||
ls -la /usr/share/libalpm/hooks/aegisaur*
|
||||
|
||||
# Manuell ausführen

sudo bash /usr/share/libalpm/hooks/aegisaur-check.sh
|
||||
```
|
||||
|
||||
### Cache-Probleme
|
||||
```bash
|
||||
# Cache leeren
|
||||
rm -rf ~/.cache/aegisaur/
|
||||
|
||||
# Neu befüllen
|
||||
aegisaur check-ioc
