I'll check whether this session is already running on the trading VPS or needs to deploy remotely via SSH.

Confirmed — this session is running directly on the trading VPS (144.217.12.244). I'll build a single-file heuristic malware/intrusion scanner tailored to this box (protects the OpenAlgo/broker credentials and trading bots), since a "real" antivirus with a signature database isn't feasible as one script — but a host-based scanner covering webshells, rootkit indicators, suspicious cron/SSH/process/port anomalies, and file-integrity drift is.

Good — passwordless sudo is available, so the scanner can do full privileged checks when run with `sudo`. Now I'll write the script.

Now let's establish a baseline and run a real scan with sudo for full coverage.

Good — the first run likely hit a cold-cache slowdown near the timeout. Baseline now correctly tracks 69 files and 20 SUID/SGID binaries. Let's run a full scan.

The scan found something worth flagging immediately: files disguised with Chromium's temp-file naming convention in `/tmp` that actually contain `curl | sh` install-script text, and several are executable. Let me inspect these before concluding anything — could be a real compromise or a headless-browser artifact from OpenClaw.

The findings are false positives, not a compromise — good to confirm, but they expose real gaps in the heuristics. Let me explain and then tighten the script: - The `/tmp/.org.chromium.Chromium.*` files are legitimate Electron/Chromium clipboard-scratch temp files from **AionUi** (`/opt/AionUi`, an installed Electron app) — they just happen to contain text that includes `curl | bash` install snippets (one is literally OpenClaw's install doc in Chinese, another is an old "Star-Office-UI" uninstall script someone had on their clipboard). Nothing is currently running from them. - Port 53 on `127.0.0.53`/`127.0.0.54` is `systemd-resolved`'s stub resolver, and port 68 is the DHCP client — both totally standard on Ubuntu. I'll fix the scanner's false-positive sources: drop the overly broad `curl|bash` content match (it stays in the cron check, where that pattern actually is suspect), stop flagging loopback-only privileged ports, and whitelist DNS/DHCP.
