Fake AnyDesk Installer Uses Windows Search Redirect to Deliver MetaStealer

· Original article ↗

Summary

Huntress traced a fake AnyDesk lure through a Cloudflare Turnstile page, Windows File Explorer and an SMB share to an MSI package that collected the victim’s hostname and dropped MetaStealer.

Key points

  • The fake installer page used a Cloudflare Turnstile-style verification lure, but redirected victims through Windows’ search-ms protocol rather than a standard ClickFix command-paste flow.
  • Windows File Explorer sent victims to an attacker-controlled SMB share, where a shortcut disguised as a PDF launched the next steps.
  • The shortcut downloaded a legitimate AnyDesk installer as a decoy and a purported PDF from chat1[.]store; the latter was an MSI package.
  • The MSI used the victim’s %COMPUTERNAME% value as a subdomain to collect the computer hostname.
  • The MSI’s CAB archive contained a cleanup script and ls26.exe, identified by Huntress as a MetaStealer dropper; observed behavior included crypto-wallet theft.
  • Huntress recommends educating users to recognize verification lures that prompt copying commands or redirect to Windows File Explorer; the article also lists associated infrastructure and file hashes.

Article Details

Attack Vectors
  • A fake AnyDesk installer page presented a Cloudflare Turnstile verification lure and redirected users through a Windows search-ms URI to an attacker-controlled SMB share.
  • The share contained an LNK shortcut disguised as a PDF. Opening it used cmd.exe to download a legitimate AnyDesk installer and a second, fake PDF that was actually an MSI package.
  • The MSI package contained a DLL, a cleanup script, and ls26.exe, identified as the MetaStealer dropper.
Defensive Notes
  • Educate users to treat CAPTCHA or verification prompts that direct them to Windows File Explorer or ask them to copy and paste commands as suspicious.
  • Consider restricting use of the Windows Run dialog where it is not needed, while recognizing that this measure does not prevent variants that use other Windows features.
