Thread opened by Winter (@winterguru); Howard (@howard9645) joined the same thread and requested the GuruScan phase. Discord thread ID 1527011066511364106.

Session Summary

Winter requested an infection check on the ScreenConnect machine named "Karen Dinius" (KARENSLAPTOP, Dell Inspiron 3582, Celeron N4000, 8GB RAM, Win 11 Home, user azgur, WORKGROUP): Karen had downloaded Slack ~7/10 and immediately afterward everything on her desktop was moved to the recycle bin. A full remote sweep was run through the ScreenConnect RESTful API (send-command + event polling for output — EventType 44 = queued command, EventType 70 = command output). Verdict: no infection. Slack.msix (162MB, downloaded 7/10 7:20 AM) carries a valid Authenticode signature from Slack Technologies, LLC and its Zone.Identifier shows it came from downloads.slack-edge.com (Slack's official CDN). Persistence points (Run keys machine+user, startup folders, scheduled tasks), browser extensions (Chrome/Edge/Firefox), and recent executables in the user profile were all clean. Avast Free + SecureLine VPN looked suspicious initially but were installed Feb 2021 — longstanding AV, which is also why Defender shows disabled. The desktop (OneDrive-synced, C:\Users\azgur\OneDrive\Desktop) is currently fully populated and the recycle bin is empty — files were already restored; the deletion was most likely accidental user action or a OneDrive sync event, coincidental with the Slack install.

Winter then asked why the machine is slow beyond being a budget model. Performance probe found the primary culprit: a Toshiba MQ04ABF100 1TB 5400RPM SATA HDD (healthy — 0 read errors, 0 wear) running Windows 11, compounded by background bloat heavy for a 2-core Celeron: Avast (~237MB), Dell SupportAssist (~228MB), SmartByte telemetry (actively using CPU), WhatsApp autostart. RAM fine (3GB free of 8GB), disk 114GB used of 932GB. Recommended: SATA SSD clone (biggest win), remove SmartByte + SupportAssist, consider replacing Avast with Defender, stop WhatsApp autostart.

Howard then requested a GuruScan. The machine was not in GuruRMM, so it was onboarded: created RMM client "Dinius, Karen" + site Main (site code EAST-STAR-6853), vaulted the enrollment key, and pushed the agent via the ScreenConnect one-liner install (https://rmm.azcomputerguru.com/install/EAST-STAR-6853/windows). Agent enrolled and came online in under a minute. The full GuruScan chain was dispatched via .claude/scripts/guruscan-agent-test.sh KarensLaptop all (prep + detached scan + collect). HitmanPro completed clean: 0 threats, 41 traces (all tracking cookies), 2,573,170 objects / 125,516 files scanned in 20.4 min. Emsisoft (a2cmd) ran ~15 min with 0 threats found before Howard requested it be killed to fast-track results (mid-scan log reads had been timing out because the 5400RPM disk was saturated); Stop-Process a2cmd -Force was dispatched via RMM, ending the chain cleanly (Emsisoft exit -1, status completed, 0 threats). Collect pulled results.json + logs to the repo. Scanner payloads (C:\GuruScan\downloads, ~320MB incl. the 304MB Emsisoft EXE) were removed post-scan; module scripts + scan logs remain per the logs-preserved invariant.

Key Decisions

  • Verified the Slack installer rather than assuming fake-installer malware — signature (valid, Slack Technologies) + Zone.Identifier HostUrl (downloads.slack-edge.com) proved the download legitimate; the desktop event was then treated as coincidental.
  • Onboarded the machine to GuruRMM as its own client "Dinius, Karen" — follows the existing individual-client naming pattern (Bardach/Key/Shinn); no existing client matched and GuruScan's deploy pipeline requires an RMM agent.
  • Killed Emsisoft mid-scan on Howard's explicit request — HitmanPro (the cloud second-opinion engine) had already completed clean and Emsisoft had 0 findings 15 min in; the Celeron/5400RPM box was too IO-saturated to even read logs mid-scan.
  • Left the GuruRMM agent enrolled pending Howard's decision (also enables the recommended remote debloat later).
  • Removed scanner payloads but kept C:\GuruScan module + C:\ScanLogs — logs-preserved invariant from the guru-scan hardening sessions.

Problems Encountered

  • SC Defender-exclusion prep step failed (0x800106ba) — Defender service dormant because Avast owns AV on the box. Harmless: Defender off means no scan interference anyway.
  • Mid-scan log reads timed out twice (RMM command reaper at 60s/240s) — Emsisoft had the 5400RPM disk fully saturated; even gc -Tail couldn't complete. Resolved by waiting, then by the kill request.
  • First sc.py invocation failed — skill doc path C:/claudetools/... doesn't exist on BEAST; actual path is C:/Users/guru/.claude/skills/screenconnect/scripts/sc.py.
  • SC send-command returns {} (documented) — output retrieved by polling session events (EventType 70 carries stdout). Worked reliably all session.

Configuration Changes

  • GuruRMM: created client Dinius, Karen (id 4ee8a212-51e2-451f-b376-c47f84eb7675), site Main (id 370f58aa-b6c4-47cf-acf0-c1a5e20ff811, site code EAST-STAR-6853).
  • Vault: added clients/dinius/gururmm-site-main.sops.yaml (enrollment api_key, client/site IDs, installer URLs) — encrypted, committed, pushed.
  • KARENSLAPTOP: GuruRMM agent installed (agent id b7ea995f-8aa8-43cf-a29a-f08a3be1860c at enroll time — resolve live, UUIDs change on re-enroll). GuruScan module at C:\GuruScan\ (payload downloads removed post-scan), scan logs at C:\ScanLogs\KARENSLAPTOP-20260715-111559\.
  • Repo: scan results pulled to projects/msp-tools/guru-scan/test-results/KarensLaptop-20260715T185338/.

Credentials & Secrets

  • GuruRMM site enrollment key for Dinius/Main: vaulted at clients/dinius/gururmm-site-main.sops.yaml (value not reproduced here — one-time api_key captured at site creation).
  • Vault paths read: infrastructure/gururmm-server.sops.yaml (RMM API admin), msp-tools/screenconnect.sops.yaml (SC API secret, via sc.py).

Infrastructure & Servers

  • KARENSLAPTOP — Dell Inspiron 3582 (SN F5C5723), Celeron N4000, 8GB RAM, Toshiba MQ04ABF100 1TB 5400RPM HDD (healthy), Win 11 Home 10.0.26200, user azgur, WORKGROUP, LAN 10.0.0.26, public 107.2.37.18, TZ Arizona. OneDrive-synced Desktop. Avast Free + SecureLine VPN (since 2021-02-21), Dell SupportAssist, SmartByte present.
  • ScreenConnect session b58d6904-86ef-4ec9-ac8f-1900d2b6495b (Support session, name "Karen Dinius", host "Computer Guru - SysAdmin").
  • GuruRMM API http://172.16.3.30:3001; install one-liner https://rmm.azcomputerguru.com/install/EAST-STAR-6853/windows.

Commands & Outputs

  • SC output retrieval pattern: sc.py send-command --session <id> --command "#!ps ..." --confirm then poll sc.py session <id> --json for EventType 70 data. #!ps + #timeout=120000 directives work through the API.
  • Slack.msix SHA256: 87360AB9A99392619B63133DBF50111E104BA599F04B21740DE16D380D723DA6; signer CN="Slack Technologies, LLC"; HostUrl https://downloads.slack-edge.com/desktop-releases/windows/x64/4.50.143/Slack.msix.
  • GuruScan result: scan_id KARENSLAPTOP-20260715-111559, total_threats 0, HitmanPro exit 0 / 0 threats / 20.43 min; Emsisoft exit -1 (killed) / 0 threats / 15.32 min.
  • Emsisoft kill: RMM powershell Get-Process a2cmd | Stop-Process -Force → A2CMD-KILLED.
  • Payload cleanup: removed C:\GuruScan\downloads (~320MB); C:\EmsisoftCmd not present.

Pending / Incomplete Tasks

  • Howard to decide: Syncro billing (customer/ticket for Dinius, Karen) — offered, awaiting reply.
  • Howard to decide: keep or uninstall the GuruRMM agent on KARENSLAPTOP.
  • Recommended follow-up work (not yet authorized): SSD clone (2.5" SATA), remove SmartByte + Dell SupportAssist, consider Avast→Defender swap, disable WhatsApp autostart.
  • Emsisoft pass was intentionally cut short — full-disk Emsisoft verdict not obtained (HitmanPro full pass was clean; risk accepted by Howard).
