## Schnellstart

## ⚡ Schnellstart (empfohlen)
|
||||
|
||||
```bash
|
||||
# Als AUR-Paket installieren (empfohlen)
|
||||
makepkg -si PKGBUILD
|
||||
# 1. Source Tarball herunterladen (enthält ALLE Dateien)
|
||||
cd /tmp
|
||||
wget https://gitea.die-heimatlosen.eu/arch_agent/aegisaur/archive/master.tar.gz
|
||||
|

# Oder systemweit nach /usr/local/bin

### Pfad auf Gitea
|
||||
```
|
||||
https://gitea.die-heimatlosen.eu/arch_agent/aegisaur
|
||||
```
|
||||
|
||||
### Installation (empfohlen)

||||
|
||||
```bash
|
||||
cd /home/arch_agent_system/.openclaw/workspace/aegisaur
|
||||
makepkg -si
|
||||
```
|
||||
|
||||
### Alternative: Git-Clone + Build
|
||||
|
||||
```bash
|
||||
git clone https://gitea.die-heimatlosen.eu/arch_agent/aegisaur.git
|
||||
# 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
|
||||
```
|
||||
|
||||
### ⚠️ Pacman-Repo Hinweis
|
||||
|
||||
> Ein pacman-Remote (`[aegisaur]` in pacman.conf) braucht eine `.db` Datei, die Gitea nicht automatisch bereitstellt. Nutze stattdessen `makepkg` oder den Release-Download.
|
||||
|
||||
### Release-Download (Fallback)
|
||||
## ⚠️ WICHTIG: Git-Clone NICHT verwenden!
|
||||
|
||||
```bash
|
||||
curl -LO https://gitea.die-heimatlosen.eu/arch_agent/aegisaur/releases/download/v0.1.0/aegisaur-0.1.0-x86_64.tar.gz
|
||||
tar xzf aegisaur-0.1.0-x86_64.tar.gz
|
||||
sudo install -Dm755 aegisaur /usr/bin/aegisaur
|
||||
# ❌ 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)
|
||||
```
|
||||
|

Trust-Scoring + IOC-Scanner für Arch Linux AUR-Pakete.
|
||||
**Vollständiger AUR Security Scanner für Arch Linux**
|
||||
|
||||
Automatisierter Schutz gegen Supply-Chain-Angriffe wie **Atomic Arch**.
|
||||
Schutz gegen Supply-Chain-Angriffe, Malware und kompromittierte Pakete im AUR.
|
||||
|
||||
## Features
|
||||
|
||||
- 🔍 **Live IOC-Abfrage** - Holt aktuelle Threat-Intelligence von Community-Quellen
|
||||
- 🛡️ **Trust-Scoring** - Analysiert PKGBUILDs auf verdächtige Muster
|
||||
- ⚡ **ALPM-Hook** - Automatischer Pre-Install-Scan
|
||||
- 📊 **Detallierte Reports** - JSON-Output für Automatisierung
|
||||
- 🔴 **Kritische Alerts** - Sofortige Warnung bei IOC-Matches
|
||||
|
||||
## Installation
|
||||
|
||||
### Aus AUR
|
||||
## ⚡ Schnellstart
|
||||
|
||||
```bash
|
||||
yay -S aegisaur
|
||||
# oder
|
||||
paru -S aegisaur
|
||||
```
|
||||
|
||||
### Manuel
|
||||
|
||||
```bash
|
||||
cargo install aegisaur
|
||||
# Download (Tarball — Git-Clone hat bekannte Probleme mit großen Dateien)
|
||||
wget https://gitea.die-heimatlosen.eu/arch_agent/aegisaur/archive/main.tar.gz
|
||||
tar xzf main.tar.gz && cd aegisaur

||||
sudo cp target/release/aegisaur /usr/local/bin/
|
||||
sudo aegisaur install-hook
|
||||
```
|
||||
|
||||
## Verwendung
|
||||
## 🎯 Features v2.0.0
|
||||
|
||||
### Einzelnes Paket scannen
|
||||
### Multi-Source Threat Intelligence
|
||||
- **HedgeDoc (Live)**: Sofort aktuell
|
||||
- **CISA KEV**: US Government Advisories
|
||||
- **Arch Security**: Offizielle Arch Linux Advisories
|
||||
- **Atomic Arch Gist**: Community-Listen
|
||||
|
||||
```bash
|
||||
aegisaur scan paketname
|
||||
```
|
||||
### Erweiterte Erkennung
|
||||
- **12 Threat-Typen**: Rootkit, Cryptominer, Backdoor, Ransomware, Infostealer, etc.
|
||||
- **AUR-Spezifisch**: Typosquatting, Orphan-Takeover, Maintainer-Kompromittierung
|
||||
- **CVE-Tracking**: Verknüpfung mit bekannten CVEs
|
||||
- **Advisory-URLs**: Direkte Links zu Security-Advisories
|
||||
|
||||
### Alle installierten AUR-Pakete scannen
|
||||
|
||||
```bash
|
||||
aegisaur scan-all
|
||||
```
|
||||
|
||||
### IOC-Check (wie `aurvulntest`)
|
||||
### Smartes Scoring
|
||||
- **AUR vs. Offizielles Repo**: Keine False-Positives für Repo-Pakete
|
||||
- **Trust-Scoring**: 0-100 mit 12 Heuristiken
|
||||
- **Cache**: 5-Minuten-TTL für maximale Aktualität
|
||||
|
||||
### Cache-Status (v2.0.1+)
|
||||
```bash
|
||||
aegisaur check-ioc
|
||||
🛡️ Prüfe IOC-Listen: all
|
||||
📦 1931 IOCs aus Cache (Alter: 2m 30s / TTL: 5m) ← Cache-Hit
|
||||
⚠️ Bedrohungen gefunden: 1
|
||||
🔴 gtkimageview - MaliciousBuildScript
|
||||
```
|
||||
|
||||
### ALPM-Hook installieren
|
||||
Cache-Miss zeigt Live-Reload:
|
||||
```
|
||||
⏰ Cache veraltet (6m 15s alt) — Live-Reload...
|
||||
🟢 1931 IOCs von HedgeDoc (LIVE)
|
||||
🟢 0 IOCs von Arch Security
|
||||
📊 Gesamt: 1931 IOCs aus Quellen: ["hedgedoc_live", "arch_security"]
|
||||
```
|
||||
|
||||
## 🚀 Befehle
|
||||
|
||||
```bash

||||
aegisaur scan-all # Alle AUR-Pakete
|
||||
aegisaur check-ioc # IOC-Listen prüfen
|
||||
sudo aegisaur install-hook # ALPM-Hook installieren
|
||||
sudo aegisaur remove-hook # ALPM-Hook entfernen
|
