Changelog

WinSentinel v1.22.0

This release ships 43 commits of new audit coverage and hardening since v1.21.0, expanding detection across network posture, PowerShell abuse, identity, and encryption.

Network posture hardening

• New checks: SMB client-side signing requirement, ICMP redirect acceptance, ICMP Router Discovery (IRDP), Dead Gateway Detection, IPv4/IPv6 source-routing acceptance, NetBIOS Name-Release-on-Demand.
• Detect active 6to4 / ISATAP IPv6 transition tunnels and add mDNS poisoning as a 4th spoofing vector (alongside LLMNR/NBT-NS/WPAD).
• Distinguish network-exposed high-risk ports from loopback-only listeners.

PowerShell & profile abuse detection

• Detect WMI/scheduled-task persistence, LOLBin execution/fetch, reverse shells, inline execution-policy bypass, and in-memory loaders in profile scripts.
• Flag AMSI reflection/kill-switch bypass (AmsiEnable=0), native-API injection, and offensive toolkit tokens (Mimikatz/Shellcode/PowerSploit).
• Audit WinRM CredSSP, Basic auth, and AllowUnencrypted plaintext transport.
• Add Protected Event Logging check; flag module logging with incomplete ModuleNames coverage and transcription without invocation headers (CIS L1).

Identity & credential protection

• Audit WDigest cleartext credential caching (UseLogonCredential).
• Correct RunAsPPL UEFI-lock semantics and recognize UEFI-locked LSA Protection; describe LSA Protection + Credential Guard.
• Registry: flag built-in Administrator bypassing UAC (FilterAdministratorToken).

Encryption

• Audit SChannel Diffie-Hellman minimum key length (Logjam) and Kernel DMA Protection.
• Flag weak BitLocker method on fully-encrypted drives; tier weak TLS cipher suites by severity (explicit 3DES/Sweet32).

Other checks & hardening

• Certificate audit: detect not-yet-valid certs; fix weak-algo thumbprint interpolation.
• Firewall: extract pure FirewallAnalyzer, detect wide-open inbound allow rules.
• Event logs: detect new account creation, privileged group additions, and successful remote logons from external IPs (4624 Type 3/10).
• Scheduled tasks: flag signed interpreters launching writable scripts.
• USB: audit WPD/MTP portable-device restriction. AppSecurity: audit MSIX/AppX sideloading & developer-mode. ASR: new Safe Mode + system-tool-impersonation rules. Browser: flag SSLVersionMin forcing TLS 1.0/1.1.

WinSentinel v1.21.0

Five new detections land in this release, expanding coverage across network posture,

Windows servicing, DNS privacy, PowerShell logging, and Microsoft Defender health. All

changes ship with new unit tests.

Network posture hardening

• WPAD auto-discovery poisoning check — NetworkAudit now flags Web Proxy

Auto-Discovery (WPAD) being left enabled, a classic man-in-the-middle vector where an

attacker on the LAN answers WPAD queries to silently redirect a machine's HTTP(S)

traffic through a rogue proxy.

Windows servicing / update health

• End-of-life build detection — UpdateAudit flags Windows installations running an

out-of-support build that no longer receives security updates, so an EOL OS is surfaced

as a finding instead of silently rotting.

DNS privacy

• DoH resolver validation — DnsAudit now flags DNS-over-HTTPS pointed at an

unrecognized / untrusted resolver, catching cases where encrypted DNS is quietly routed

through an unexpected third party.

PowerShell logging fidelity

• Explicitly-disabled vs. unset logging — PowerShell logging analysis now

distinguishes a policy value explicitly set to 0 (logging deliberately turned off)

from a value that is simply absent, reducing false "not configured" noise and correctly

escalating deliberate tamper-down of Script Block / Module logging.

Microsoft Defender health

• Protection-disabled event detection — the event-log analyzer now detects Windows

Defender protection-disabled events (IDs 5001 / 5010 / 5012), surfacing real-time

protection or antivirus/antispyware being switched off — a common precursor to malware

execution.

Packages

• WinSentinel.Cli and WinSentinel.Core publish to NuGet.org and GitHub Packages once

the release automation finishes indexing.

• MSIX + portable/service ZIP assets are built and attached by the release workflow.

Full Changelog: https://github.com/sauravbhattacharya001/WinSentinel/compare/v1.20.2...v1.21.0

WinSentinel v1.20.2

This ships the v1.20.0 payload — the ~110-commit hardening batch — as the first release of this line to actually reach NuGet.

What's in this line

• RemoteAccess hardening: RDP / WinRM checks and fixes tightened.
• Microsoft Defender coverage: Attack Surface Reduction (ASR), Controlled Folder Access (CFA), and PUA protection checks.
• Parser hardening across the check pipeline for more robust input handling.
• Dead "Fix" button repairs — several checks whose remediation button was a no-op now actually apply their fix.
• LLMNR FixCommand fix — the LLMNR remediation now runs the correct command.
• Scope reduction: the Pro fleet feature was removed from the OSS core, so this build is single-machine only.

Why v1.20.2 (and not v1.20.0 / v1.20.1)

v1.20.0 and v1.20.1 were tagged but never published to NuGet: the release pipeline re-ran the full test suite as a hard publish gate and tripped on environment-flaky tests (registry / async-timing) on the hosted runners. That redundant gate has been removed — publishing is now build → pack → push, with CI remaining the test gate — so v1.20.2 is the first release of this line to actually publish to NuGet. It supersedes v1.20.0 and v1.20.1, which stay as-is.

Full Changelog: https://github.com/sauravbhattacharya001/WinSentinel/compare/v1.20.1...v1.20.2

WinSentinel v1.20.1

This is a patch release that ships the full v1.20.0 payload plus a fix to the LLMNR remediation so the package actually publishes to NuGet. v1.20.0's own publish step failed on a FixCommand test, so v1.20.1 supersedes it as the installable release.

Fix in this release

• LLMNR remediation now uses PowerShell Set-ItemProperty to write the EnableMulticast DWORD under HKLM\Software\Policies\Microsoft\Windows NT\DNSClient. The previous reg add form failed the FixCommand unit test and blocked the NuGet publish. The remediation behaviour is unchanged; only the command form was corrected so CI is green and the package can ship.

Included from v1.20.0 (110-commit hardening batch)

• RemoteAccess / RDP / WinRM family checks and remediations.
• Microsoft Defender coverage: Attack Surface Reduction (ASR) rules, Controlled Folder Access (CFA), and Potentially Unwanted Application (PUA) protection.
• Parser hardening across the check pipeline for more robust input handling.
• Dead "Fix" button repairs — remediation actions that previously no-oped are now wired up correctly.

Full Changelog: https://github.com/sauravbhattacharya001/WinSentinel/compare/v1.20.0...v1.20.1

WinSentinel v1.20.0

A large release: 110 commits since v1.19.1, adding two new audit modules, a broad set of

Remote Access and Microsoft Defender checks, several new CLI commands, and a wide sweep of

analyzer hardening, parser correctness fixes, and Fix-button repairs. Scheduled scans and the

real-time monitor are now free (full single-machine power); Pro is fleet-only.

New audit modules

• Identity & Credentials audit — credential hygiene and identity posture checks.
• USB & Removable Media audit (F6) — removable-storage exposure and policy.

Remote Access hardening

• Audit RDP drive + clipboard and printer + COM/LPT redirection policy.
• Flag RDP session shadowing that allows silent view/control without consent.
• Audit RDP Plug-and-Play device redirection (fDisablePNPRedir) and always-prompt-for-password-on-connect (fPromptForPassword).
• Flag WinRM listeners that accept connections from any source IP.
• Audit WinRM CredSSP delegation and wildcard TrustedHosts.
• Warn on unsolicited Remote Assistance (Offer RA).

Microsoft Defender

• Audit Attack Surface Reduction (ASR) rules with a one-click enable-all fix.
• Audit Controlled Folder Access with a one-click enable fix.
• Audit PUA (potentially-unwanted application) protection.
• Detect tampered profile.ps1 PowerShell persistence (T1546.013).

New CLI commands & UX

• winsentinel diff — standalone posture-diff command.
• winsentinel why — per-finding explanations.
• winsentinel agent — start/stop/status/install/uninstall the background agent.
• winsentinel fleet commands — Pro dispatch-history view (fleet: status, scan-all, push-policy, nodes).
• badge command handler and polished findings export (flag-style formats, smart defaults, CSV).

Compliance

• Added SOC 2 and Essential 8 framework mappings.

Ecosystem & distribution

• GitHub Action for the Marketplace ("winsentinel security audit") plus CI security-audit actions and SARIF/JSON export wiring.
• winget manifest with auto-submission; opt-in telemetry service + CLI command.
• Localization scaffolding (en-US) with Spanish translation wired into severity labels.
• Plugin architecture repurposed as community extensibility (no longer Pro-gated).

Reliability: analyzer extraction + test expansion

• Extracted pure, unit-testable analyzers from their audits — Defender, USB, NetworkPosture,

PowerShellSecurity, BrowserSecurity, Encryption, IdentityCredential, EventLog, ProcessLineage —

plus FleetRequestBuilder and WatchDeltaCalculator.

• Hundreds of new tests across services (KillChain, FlightRecorder, Kpi, Prophecy, Canary,

ThreatHunt, Mentor, Autopsy, MaturityAssessment, AgentService) and audits.

Correctness, parser hardening & Fix-button repairs

• Repaired multiple dead Fix buttons and guarded every analyzer fix command against the

sanitizer so the Fix button actually works; added actionable fixes to Encryption findings.

• Hardened parsers: LLMNR/NetBIOS, SMB/RDP registry flags, listening-ports, IPv6/Teredo,

arp -a lines, and audit-policy/EventLog boundaries.

• Fixed EncryptionAnalyzer BitLocker %/TPM handling, NetworkPosture WPA/cipher classification,

EventLog retention semantics, ComplianceMapper word-boundary matching, ScoreForecaster /

SecurityDecayPredictor / streak/heatmap date-boundary bugs, SARIF rule-ID trailing hyphen,

and CSV formula-injection bypass in export --csv.

_Release assets (MSIX, portable/service ZIPs) are attached by the Release workflow;

WinSentinel.Cli / WinSentinel.Core publish to NuGet.org once the NuGet workflow finishes indexing._

Full Changelog: https://github.com/sauravbhattacharya001/WinSentinel/compare/v1.19.1...v1.20.0

v1.19.1 — Plugin System Refinements

Follow-up improvements to the community plugin architecture:

• Improved plugin isolation: Plugins load in separate AssemblyLoadContexts for safety
• Better error handling: Graceful degradation when a plugin fails to load
• Plugin validation: Schema checks on plugin manifests before loading
• Documentation: Added plugin authoring guide to the wiki

The plugin system is fully open — no license or paid tier required. Build and share audit plugins freely.

v1.19.0 — Plugin Architecture for Community Extensibility

WinSentinel now supports a fully open plugin architecture. Anyone can write custom audit plugins to extend the security scanning engine:

• Open ecosystem: Write your own audit modules using the IAuditPlugin interface
• Drop-in loading: Place plugin DLLs in the plugins directory — auto-discovered at runtime
• Full API access: Plugins get the same finding/severity/fix infrastructure as built-in modules
• Community-driven: Share plugins via NuGet or GitHub — no gatekeeping, no paid tiers required

This release lays the foundation for a vibrant community of security-focused developers building specialized audit modules for their environments.

Other changes

• Plugin discovery and loading infrastructure
• Plugin manifest schema for metadata and versioning
• Sample plugin template included in the repo

v1.18.0 — Threat Horizon Forecaster + machine-readable --version

A focused minor release that adds one new agentic advisor and finally makes

winsentinel --version safe to call from CI, inventory, and packaging scripts.

✨ New: Threat Horizon Forecast Advisor

ThreatHorizonForecastAdvisor is the sixth agentic sibling alongside

FixOrchestrationPlanner, AlertRoutingAdvisor, AttackerProfileSynthesizer,

PostureRegressionExplainer, and PolicyExceptionRiskAdvisor.

It produces a forward-looking 7-day threat-pressure forecast (0–100) by

blending recent attacker-side recon signals with defender-side posture context:

• Attacker signals (8): port scans, brute-force attempts, IOC matches,

phishing waves, rogue DNS, dark-web mentions, anomalous outbound, etc.

Each contribution is weighted by velocity, freshness, and distinct-source

dedup so a single noisy source can't dominate.

• Defender overhang (5): open critical findings, attack-surface size,

recent posture regressions, recently revoked exceptions, exposed assets.

• Risk-appetite shift: Cautious +5 / Aggressive −5.
• Verdict ladder: Calm → Elevated → Imminent → UnderPressure,

graded A–F.

• Per-day forecast curve with attacker-decay modeling.
• P0-first hardening playbook (BLOCK_KNOWN_IOCS, RATE_LIMIT_AUTH,

HARDEN_PERIMETER, war-room convene on 2+ P0s, …).

• Cross-signal insights: network / auth / user heat concentration,

compound pressure, sustained pressure.

• Renderers: Text / Markdown / JSON.

🐛 Fixes

• #194 — Machine-readable --version. Adds two CI/inventory-friendly

variants that compose with the existing 4-line human banner:

• winsentinel --version --quiet → bare version string (e.g. 1.18.0)
• winsentinel --version --json → stable JSON

{ product, version, informationalVersion, runtime, os, machine }

After --version, only --quiet / --json are greedily consumed; any

other trailing flag is rejected with a clear error.

• #192 — --version now reflects the real installed version.

PrintVersion was reading Assembly.GetName().Version, which returns

the static AssemblyVersion attribute (pinned at 1.0.0.0 for binding

stability). With MinVer driving the package version from git tags into

AssemblyInformationalVersion, the printed banner was stuck at v1.0.0

even though the installed tool was 1.16.1+. Switched the banner to read

AssemblyInformationalVersionAttribute (with AssemblyFileVersion +

AssemblyName.Version as fallbacks) and strip the SourceLink

+commitsha metadata so the output stays clean for support tickets.

Covered by 4 new regression tests in ConsoleFormatterTests.

🧹 Maintenance

• Dependabot config: group minor+patch updates (NuGet, GitHub Actions,

Docker) into single PRs per ecosystem, add an analyzers group, expand

the test-stack group, and **ignore semver-major bumps on

mcr.microsoft.com/dotnet/{sdk,runtime,aspnet}** base images. The

Dockerfile is pinned to 8.0-windowsservercore-ltsc2022 to match the

net8.0-windows TFM across every project; major base-image bumps

require a coordinated TFM migration and are now tracked manually

instead of re-opened weekly by Dependabot.

v1.16.1 — Elevated FixEngine wrapper hardening

🔒 Security

• FixEngine.ExecuteElevatedAsync: escape apostrophes in temp paths before embedding them in the elevated PowerShell wrapper.

The elevated remediation path builds a PowerShell try/catch wrapper around Path.GetTempPath()-derived script/output/error paths and runs it with Verb=runas (UAC). GUID nonces kept the file names safe, but the directory portion (%USERPROFILE%\AppData\Local\Temp by default) is attacker-influenceable — a Windows account display name containing an apostrophe (e.g. O'Brien) or a hijacked TEMP / TMP env var would close the PowerShell single-quoted literal and turn the wrapper into a command-injection sink running with administrator privileges.

The fix adds EscapePowerShellSingleQuoted (doubles every ', matching the PowerShell / SQL single-quoted escape rule) and applies it to the script, output, and error paths before interpolation.

✅ Tests

• New FixEngineTests.EscapePowerShellSingleQuoted_* theory + null case covering plain, empty, normal Windows temp paths, apostrophe-bearing user paths, raw injection payloads, and null.

🧱 Build

• WinSentinel.Core.csproj: switch to the proper <ItemGroup>-scoped <InternalsVisibleTo Include="WinSentinel.Tests" /> form so the test project can exercise the new internal helper.

WinSentinel v1.16.0

A feature-heavy release expanding MITRE ATT&CK coverage and polishing the agentic analysis layer. 25 commits since v1.15.1.

New: ATT&CK Detector Suite

Five new autonomous detectors stitched into the analysis pipeline:

• Credential Access Detector (TA0006) — LSASS dumping, Kerberoasting, brute-force, password spraying, keylogging, NTLM relay, and more. Builds harvest chains and recommends containment.
• Initial Access Detector (TA0001) — phishing, exploit-public-facing, supply-chain, valid-account abuse.
• Discovery Detector (TA0007) — host/network/account reconnaissance signal extraction.
• Execution Detector (TA0002) — script interpreter abuse, scheduled-task / WMI execution, LOLBin patterns.
• Command & Control Detector (TA0011) — beaconing, encrypted-channel and proxy abuse heuristics.

Performance

• SecurityNerveCenter now sorts audit history once and threads the result through BuildSignals / BuildAlerts instead of re-sorting per call.
• InsiderThreatProfiler.DetectDeviations collapsed 6+ separate Where().Count() passes into a single-pass event bucketing loop.

Refactors / Reliability

• InsiderThreatProfiler risk-tier classification cleanup: removed an unreachable Critical arm in the first ternary that was immediately shadowed by a corrective if/else ladder; collapsed both into a single highest-first ClassifyInsiderRiskLevel helper with a named CriticalRiskThreshold = 85 constant.
• NuGet publish workflow fix.
• Preview package CI for pre-release builds.

CI / Release Plumbing

• nuget.yml triggers on published releases and packs both WinSentinel.Core and WinSentinel.Cli against the release tag version.
• Version-sync workflow keeps csproj <Version> aligned with MinVer-derived tags.

Install

dotnet tool install --global WinSentinel.Cli --version 1.16.0

_Tag-driven release; NuGet publish workflow will run automatically on publish._

Bug Fix

🐛 Fixed: Stack Overflow crash in EventLogAudit module

Impact: WinSentinel crashed with a StackOverflowException every time an audit was run (--audit, --score, or any command that triggers the EventLog module).

Root Cause: The AddFinding and AddFindings helper methods in EventLogAudit.cs were calling themselves recursively inside a lock block instead of calling esult.Findings.Add(). This caused infinite recursion (19,234+ calls) until the stack overflowed.

Fix: Replaced recursive self-calls with direct esult.Findings.Add(finding) operations.

This was introduced in v1.11.0 and affected all subsequent versions through v1.15.0.
