|
||||
|
||||
## 1. SSH Security
|
||||
|
||||
### 1.1 Configuration Check
|
||||
```bash
|
||||
# Run on server:
|
||||
grep -E "^PasswordAuthentication|^PermitRootLogin|^MaxAuthTries|^PubkeyAuthentication" /etc/ssh/sshd_config
|
||||
```
|
||||
|
||||
| Setting | Expected | Actual | Status |
|
||||
|---------|----------|--------|--------|
|
||||
| PasswordAuthentication | no | | ⬜ |
|
||||
| PermitRootLogin | no | | ⬜ |
|
||||
| MaxAuthTries | 3-5 | | ⬜ |
|
||||
| PubkeyAuthentication | yes | | ⬜ |
|
||||
|
||||
### 1.2 Authorized Keys
|
||||
```bash
|
||||
# Check for unauthorized keys:
|
||||
cat ~/.ssh/authorized_keys
|
||||
cat /root/.ssh/authorized_keys 2>/dev/null
|
||||
```
|
||||
- [ ] Only expected keys present
|
||||
- [ ] No unknown public keys
|
||||
|
||||
### 1.3 Recent Login Attempts
|
||||
```bash
|
||||
# Check for brute force:
|
||||
grep "Failed password" /var/log/auth.log | tail -20
|
||||
# Check successful logins:
|
||||
grep "Accepted" /var/log/auth.log | tail -20
|
||||
```
|
||||
- [ ] No successful unauthorized logins
|
||||
- [ ] Brute force attempts are being blocked
|
||||
|
||||
---
|
||||
|
||||
## 2. Firewall (UFW)
|
||||
|
||||
### 2.1 Status Check
|
||||
```bash
|
||||
sudo ufw status verbose
|
||||
```
|
||||
|
||||
| Port | Service | Should Allow | Status |
|
||||
|------|---------|--------------|--------|
|
||||
| 22 | SSH | Yes | ⬜ |
|
||||
| 80 | HTTP | Yes | ⬜ |
|
||||
| 443 | HTTPS | Yes | ⬜ |
|
||||
| 2375 | Docker API | **NO** | ⬜ |
|
||||
| 2376 | Docker TLS | **NO** | ⬜ |
|
||||
| 27017 | MongoDB | **NO** (localhost only) | ⬜ |
|
||||
|
||||
### 2.2 Default Policy
|
||||
```bash
|
||||
sudo ufw status verbose | grep Default
|
||||
```
|
||||
- [ ] Default incoming: deny
|
||||
- [ ] Default outgoing: allow
|
||||
|
||||
---
|
||||
|
||||
## 3. Docker Security (CRITICAL)
|
||||
|
||||
### 3.1 Docker Installation Status
|
||||
```bash
|
||||
which docker
|
||||
docker --version 2>/dev/null || echo "Docker not installed"
|
||||
```
|
||||
|
||||
| Check | Status |
|
||||
|-------|--------|
|
||||
| Docker installed? | ⬜ Yes / ⬜ No |
|
||||
| If yes, is it necessary? | ⬜ Yes / ⬜ No |
|
||||
|
||||
### 3.2 If Docker IS Installed
|
||||
|
||||
```bash
|
||||
# Check running containers:
|
||||
docker ps -a
|
||||
# Check Docker socket exposure:
|
||||
ls -la /var/run/docker.sock
|
||||
# Check Docker API binding:
|
||||
ss -tlnp | grep docker
|
||||
```
|
||||
|
||||
- [ ] No unnecessary containers running
|
||||
- [ ] Docker socket not world-readable
|
||||
- [ ] Docker API NOT bound to 0.0.0.0
|
||||
- [ ] UFW blocks ports 2375/2376
|
||||
|
||||
### 3.3 Recommendation
|
||||
**If Docker is not essential, REMOVE IT:**
|
||||
```bash
|
||||
sudo apt purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
|
||||
sudo rm -rf /var/lib/docker /var/lib/containerd
|

|
||||
|
||||
## 3. Entry Vector Analysis
|
||||
|
||||
### 3.1 What Was NOT Compromised
|
||||
|
||||
| Vector | Status | Evidence |
|
||||
|--------|--------|----------|
|
||||
| SSH | CLEAN | All logins from legitimate IPv6 + key |
|
||||
| MongoDB | CLEAN | Bound to 127.0.0.1, auth enabled |
|
||||
| Tractatus App | CLEAN | server.js hash matches local |
|
||||
| Host OS | CLEAN | No rogue users, cron jobs, or modified binaries |
|
||||
| nginx | CLEAN | Config hash verified |
|
||||
| systemd | CLEAN | Service file hash verified |
|
||||
| SSH Keys | CLEAN | Only legitimate deploy key present |
|
||||
|
||||
### 3.2 What WAS Compromised
|
||||
|
||||
| Component | Status | Evidence |
|
||||
|-----------|--------|----------|
|
||||
| Docker Container | COMPROMISED | Malware files in overlay2 |
|
||||
| Umami Analytics | LIKELY ENTRY POINT | Web-facing container |
|
||||
|
||||
### 3.3 Probable Entry Method
|
||||
|
||||
The **Umami Analytics container** (`ghcr.io/umami-software/umami:postgresql-latest`) was the likely entry point:
|
||||
|
||||
1. Container exposed to network
|
||||
2. Possible vulnerability in Umami
|
||||
3. OR default/weak credentials
|
||||
4. OR exposed Docker API
|
||||
|
||||
**Note**: No unauthorized SSH access was detected. All 30 recent logins were from the same legitimate IPv6 address with the correct SSH key.
|
||||

|
||||
|
||||
## 4. Impact Assessment
|
||||
|
||||
### 4.1 What Was Affected
|
||||
|
||||
| System | Impact | Details |
|
||||
|--------|--------|---------|
|
||||
| Website | DOWN | VPS in rescue mode |
|
||||
| Database (MongoDB) | INTACT | No evidence of access |
|
||||
| User Data | NONE | No users except admin |
|
||||
| Credentials | EXPOSED | Git history had credential files |
|
||||
| IP Reputation | DAMAGED | May be blacklisted |
|
||||
|
||||
### 4.2 What Was NOT Affected
|
||||
|
||||
- Tractatus application code (hash verified)
|
||||
- MongoDB data integrity
|
||||
- SSL certificates
|
||||
- DNS configuration
|
||||
- GitHub repositories

|
||||
|
||||
## 5. Forensic Evidence Summary
|
||||
|
||||
### 5.1 File System Analysis
|
||||
|
||||
**Modified files in last 24h (excluding Docker/logs)**:
|
||||
- All legitimate deployment files from today's translation work
|
||||
- Normal system cache updates
|
||||
- PostgreSQL WAL files (normal operation)
|
||||
|
||||
**No modifications to**:
|
||||
- /etc/passwd (no rogue users)
|
||||
- /etc/cron.* (no malicious cron jobs)
|
||||
- /usr/bin, /usr/sbin (no modified binaries)
|
||||
- ~/.ssh/authorized_keys (only legitimate key)
|
||||
|
||||
### 5.2 Log Analysis
|
||||
|
||||
**SSH Auth Log**: Heavy brute force from multiple IPs:
|
||||
- 92.118.39.x (trying: solv, node, ps, mapr)
|
||||
- 80.94.92.x (trying: sol, solana, trader)
|
||||
- 31.58.144.6 (trying: root)
|
||||
- 193.46.255.7 (trying: root)
|
||||
|
||||
**Result**: ALL failed - no successful unauthorized logins
|
||||
|
||||
### 5.3 Integrity Verification
|
||||
|
||||
| File | Local Hash | Production Hash | Status |
|
||||
|------|------------|-----------------|--------|
|
||||
| src/server.js | 884b6a4874867aae58269c2f88078b73 | 884b6a4874867aae58269c2f88078b73 | MATCH |
|
||||
| public/*.js count | 123 | 123 | MATCH |
|
||||
| src/*.js count | 139 | 139 | MATCH |
|
||||

|
||||
|
||||
## 6. Recovery Options
|
||||
|
||||
### Option A: Full Reinstall (Safest)
|
||||
**Pros**: Eliminates any hidden persistence
|
||||
**Cons**: More time, reconfiguration needed
|
||||
**Risk**: LOW
|
||||
|
||||
### Option B: Clean Docker + Redeploy (Recommended)
|
||||
**Pros**: Faster, maintains configuration
|
||||
**Cons**: Small risk of missed persistence
|
||||
**Risk**: LOW-MEDIUM (mitigated by evidence showing containment)
|
||||
|

## 7. Recommended Recovery Steps (Option B)
|
||||
|
||||
### Phase 1: Clean Docker (In Rescue Mode)
|
||||
```bash
|
||||
# Mount disk
|
||||
mount /dev/sdb1 /mnt/vps
|
||||
|
||||
# Remove all Docker data
|
||||
rm -rf /mnt/vps/var/lib/docker/*
|
||||
rm -rf /mnt/vps/opt/containerd/*
|
||||
|
||||
# Disable Docker autostart
|
||||
rm /mnt/vps/etc/systemd/system/multi-user.target.wants/docker.service 2>/dev/null
|
||||
```
|
||||
|
||||
### Phase 2: Security Hardening
|
||||
```bash
|
||||
# Block Docker ports via UFW (add to /etc/ufw/user.rules)
|
||||
-A ufw-user-input -p tcp --dport 2375 -j DROP
|
||||
-A ufw-user-input -p tcp --dport 2376 -j DROP
|
||||
|
||||
# Disable password auth in sshd_config
|
||||
sed -i 's/.*PasswordAuthentication.*/PasswordAuthentication no/' /mnt/vps/etc/ssh/sshd_config
|
||||
|
||||
# Install fail2ban (after reboot)
|
||||
```
|
||||
|
||||
### Phase 3: Request Normal Boot
|
||||
Contact OVH support to restore normal boot mode.
|
||||
|
||||
### Phase 4: Post-Boot Actions
|
||||
```bash
|
||||
# Verify services
|
||||
sudo systemctl status tractatus
|
||||
sudo systemctl status mongod
|
||||
sudo systemctl status nginx
|
||||
|
||||
# Rotate credentials
|
||||
node scripts/fix-admin-user.js admin@agenticgovernance.digital 'NEW_PASSWORD'
|
||||
|
||||
# Update .env with new secrets
|
||||
# Redeploy from clean local source
|
||||
./scripts/deploy.sh --yes
|
||||
```
|
||||
|
||||
### Phase 5: Remove Docker (If Not Needed)
|
||||
```bash
|
||||
sudo apt purge docker-ce docker-ce-cli containerd.io
|
||||
sudo rm -rf /var/lib/docker /var/lib/containerd
|
||||
```
|
||||

|
||||
|
||||
## 8. Preventive Measures
|
||||
|
||||
### Immediate
|
||||
- [ ] Rotate all passwords (admin, MongoDB, etc.)
|
||||
- [ ] Remove Docker or secure it properly
|
||||
- [ ] Enable fail2ban
|
||||
- [ ] Review UFW rules
|
||||
- [ ] Disable SSH password auth
|
||||
|
||||
### Long-term
|
||||
- [ ] Never expose Docker API to network
|
||||
- [ ] Use Docker rootless mode if Docker needed
|
||||
- [ ] Implement intrusion detection (OSSEC/Wazuh)
|
||||
- [ ] Set up log monitoring/alerting
|
||||
- [ ] Regular security audits
|
||||
- [ ] Remove credential files from git history (BFG Repo-Cleaner)

## 9. Lessons Learned
|
||||
|
||||
1. **Docker containers are attack surfaces** - Even "analytics" containers can be compromised
|
||||
2. **Container isolation ≠ security** - Containers had network access to launch attacks
|
||||
3. **Defense in depth works** - UFW, MongoDB auth, SSH keys prevented host compromise
|
||||
4. **Git credential exposure is dangerous** - Historical credential files may have aided reconnaissance
|
||||
5. **OVH detection is fast** - Attack stopped within seconds of detection
