ValleyRAT is hiding inside QN Wallpaper, a genuine signed Chinese desktop app that bundles adware. Because the adware trips antivirus, users add it to the exclusion list — and the backdoor rides in through the hole they made. Kaspersky counted over 100,000 detections across 1,500-plus users, mostly in China and India.
TerminalFix is ClickFix with one substitution. A fake Cloudflare CAPTCHA asks you to paste a command, and instead of the Run dialog it sends you to Windows Terminal or PowerShell — where long multi-line scripts actually work.

Sleepwalker is a Windows backdoor with a 23-instruction custom bytecode language, AES-256-CCM, and no outbound connections at all. It sits dormant until a specially crafted packet arrives. It loads by side-loading through a security vendor's own management agent while pretending to be Microsoft's dpapi.dll — and the researcher who found it says plainly that he cannot name a single victim.
