SSH keys changed; port 2283 added | | james-old (192.168.1.17) | âš ī¸ WARNING | RDP 3389 still open (ongoing); k2-watchdog cron | | staging (192.168.1.253) | ✅ CLEAN | All expected services; logins clean | | prod (192.168.100.2) | ✅ CLEAN | SSH restored; services expected | --- ## Forge (localhost / 192.168.1.16) ### 🔴 CRITICAL: Python HTTP Server Exposing /tmp on Port 9999 - Process: `python3 -m http.server 9999 --bind 0.0.0.0` - CWD: `/tmp` — serving the ENTIRE /tmp directory to all interfaces - Binary: `/usr/bin/python3.12 (deleted)` — orphaned process, binary was updated/deleted - UFW: Port 9999 accessible from entire LAN (192.168.0.0/22 → ALLOW Anywhere rule) - **Files exposed:** `clawvault-preview.db`, `clawvault-preview.db-shm/wal`, `cron_keys.txt`, `Caddyfile.bak`, `Caddyfile.new`, dev logs, API test files, android APKs, SQL dumps, etc. - **Action needed:** Kill this process immediately — `kill 866793` - **Origin:** Started ~Mar 7 01:14 AM, likely left running from a dev session ### âš ī¸ New SSH Key: hans@vault1984-hq - Added to `~/.ssh/authorized_keys` on Mar 8 at 01:46 AM - Comment: `hans@vault1984-hq` — appears to be vault1984 project key - Not in baseline (baseline was last updated Mar 1) - **Action:** Confirm this is intentional; update baseline if so ### âš ī¸ New Service: agentchat on Port 7777 - Binary: `/home/johan/dev/agentchat/agentchat` - Started ~Mar 8 04:55 AM - Not in baseline - **Action:** Confirm intentional; add to baseline if so ### ✅ FIXED: SSH Hardening (Previously Critical) - `passwordauthentication no` ✅ ← FIXED from last week's critical finding! - `permitrootlogin no` ✅ - `pubkeyauthentication yes` ✅ ### ✅ Clean Items - UFW: active ✅ - fail2ban: running, 0 bans (expected for LAN machine) ✅ - Users: johan:1000, scanner:1001 — match baseline ✅ - SSH keys (known): james@server, johan@ubuntu2404, claude@macbook, johanjongsma@Johans-MacBook-Pro.local, johan@thinkpad-x1 — all match baseline ✅ - Logins: all from 192.168.1.14 (Johan's MacBook) ✅ - Failed logins: none ✅ - Crontab: backup-forge, claude-usage-check, ddns-update, health-push — all known ✅ - vault1984 on 1984, 9900 (docproc), dealspace 9300 — expected ✅ --- ## Zurich (zurich.inou.com / 82.22.36.202) ### ✅ Upgradable Packages: 1 - Down from 17 last week — packages were updated ✅ - 1 remaining package — low urgency ### ✅ Brute Force (Expected for Public VPS) - fail2ban stats not captured this scan (output truncated) - All SSH connections still restricted to key-only ✅ ### ✅ Clean Items - SSH hardened: passwordauth no, permitroot without-password ✅ - UFW active with expected rules ✅ - Docker: uptime-kuma (healthy), vaultwarden (healthy) ✅ - Services: stalwart-mail on all expected ports, caddy on 80/443 ✅ - Crontab: vaultwarden-backup, stalwart-allowlist-sync, config-backup, certbot, nuclei-monthly — all expected ✅ - Last logins from home public IP only ✅ --- ## Caddy (192.168.0.2) ### âš ī¸ New User: hans:1002 - `hans:x:1002:1005::/home/hans:/bin/bash` - NOT in baseline (baseline: nobody, johan:1000, stijn:1001) - Shell set to /bin/bash with home at /home/hans - Correlates with `hans@vault1984-hq` key on forge — same person/project - **Action:** Confirm who added this user and why; update baseline if intentional ### âš ī¸ SSH Keys Changed - Current root authorized_keys: only `james@forge` (1 key) - Baseline had 3 keys: james@forge, claude@macbook, johan@ubuntu2404 - **2 keys removed** — actually reduces attack surface (good), but unexplained change - **Action:** Update baseline to reflect current state ### âš ī¸ Port 2283 (Caddy binding) - Caddy listening on 2283 — likely new reverse proxy entry for Immich - Not in baseline (baseline: 22, 80, 443, 40021, 2019-lo, 53-lo) - No corresponding UFW rule visible — may be LAN-accessible - **Action:** Confirm Caddy is proxying Immich on this port; add to baseline ### ✅ Clean Items - SSH hardened: passwordauth no, permitroot without-password ✅ - UFW active ✅ - fail2ban: not active (known — unchanged from baseline) - Logins: `reboot system boot` only (no user logins) — suggests rarely accessed ✅ - Failed logins: none ✅ - TLS cert: valid, `notAfter=Jun 3 2026` (~86 days remaining) ✅ - Crontab: daily config-backup to git ✅ - SSH daemon: responding normally ✅ (was showing "connection refused" last week — resolved) - stijn user: present as expected ✅ --- ## James-Old (192.168.1.17) ### âš ī¸ RDP Port 3389 (Ongoing) - Still open from last scan — investigation pending - Process: xrdp (confirmed — shows in process list) - LAN-only exposure;
