||||
|
||||
## 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).
