MacOS Security Assessment Summary | Generated by AI
Here’s my full security assessment of this macOS machine:
Login Activity Summary
Only one user has logged in: lzwjava (plus the system root account, which is normal).
| When | User | Terminal | Notes |
|---|---|---|---|
| Sun Apr 12 22:36 (tonight) | lzwjava | ttys010 | Still logged in (this AI agent) |
| Sun Apr 12 22:32 (tonight) | lzwjava | ttys001 | Still logged in (terminal) |
| Sat Apr 11 22:31 | lzwjava | ttys009 | Still logged in |
| Sat Apr 11 05:55 | lzwjava | ttys007 | Still logged in |
| Fri Apr 10 21:45 (boot time) | lzwjava | console + 4 ttys | Still logged in |
The machine rebooted Friday Apr 10 at 21:41, which explains why many sessions say “still logged in” – they’re just stale entries from the pre-reboot session. The last root login was at console for 1 minute before shutdown. No suspicious remote (SSH) logins anywhere in the log.
Security Assessment: LOW RISK
No obvious signs of compromise, but here’s what I found:
What looks normal:
- Only one user account (
lzwjava) with actual logins – no unknown users - No failed login attempts recorded
- No SSH login attempts at all (good if you don’t use SSH)
- Three admin accounts exist:
root,macadmin,lzwjava–macadminis a standard macOS admin group account - No SSH authorized_keys files found (no unauthorized SSH key access)
- No cron jobs
- Running processes are all recognizable apps
Things worth noting (not necessarily bad):
- Proxy/VPN tools: ClashX Pro, ShadowsocksX-NG, and V2RayU are installed. These are common in China for GFW-bypass, but open listening ports that could theoretically be misconfigured
- nginx on port 8081: Running as user lzwjava – check if you intentionally set this up
- Redis on port 6379: Bound to localhost only, so not externally accessible
- PostgreSQL on port 5432: Bound to localhost only, same as Redis
- WeChat listening on multiple localhost ports – normal behavior
- mihomo (clash-based proxy) running as active process (PID 92432)
- Multipass (Canonical VM tool) and Docker daemon helpers are installed
Recommendations if you’re concerned:
- Run
sudo log show --predicate 'eventMessage contains "authentication"' --last 24hin a local terminal to see all authentication events - Check if port 8081 (nginx) is intentional – if not, stop it with
brew services stop nginx - Make sure Firewall is enabled:
sudo /usr/libexec/ApplicationFirewall/socketfilterfw --getglobalstate - Change your password if you have any doubt: System Preferences > Users & Groups
