v2.0.1 — Defender false-positive hotfix
Why this release exists
Windows Defender's heuristic ML model started flagging
SignalRGBBridge.exe as Trojan:Win32/Wacatac.B!ml on some
systems after the v2.0.0 release. The new behaviour delta that
pushed the score over the threshold was the in-app Wallpaper
Pack downloader — combining urllib.request.urlopen +
hashlib.sha256 + zipfile.extractall on an unsigned binary that
already binds a UDP port + websocket + writes an autostart
registry entry matched Defender's textbook Stage-2-loader
heuristic. False positive, but a real user-facing problem.
What changed
- In-app pack downloader removed. Bridge no longer reaches out
to GitHub for pack manifests, downloads ZIPs, or extracts them
into the library directory. The matching<details>block in
the Library tab now points at the same GitHub release where the
pack ZIPs live; users grab them and extract by hand. - Library tab keeps the per-source filter chip row + section
headers — manually-extracted packs still light those up. library-packs-v1release still carries all 13 themed pack
ZIPs + the 52 preview thumbs. Public URL pattern unchanged.
How to add the optional themed packs (manual flow)
- Open the
library-packs-v1
release. - Download the pack ZIP(s) you want (
aurora-pack-v1.zip,
cyberpunk-pack-v1.zip, …). - Extract the contents of each ZIP directly into
%LOCALAPPDATA%\SignalRGBWallpaper\library\. No subfolder —
the WebPs sit alongside your existing library content. - Open the Configurator's Library tab. The bridge rebuilds the
catalogue on the next render and the new tiles appear.
Coming back later
We're evaluating
Azure Trusted Signing
(~$10/month, no hardware token) + a separate small downloader
binary so the in-app flow can come back without re-tripping
Defender. Track progress on the repo Issues.
If Defender still flags SignalRGBBridge.exe after this update,
please
submit the binary as a false positive
— that's the only path that clears it for all users at once.
