Daydream
Fake Steam client that a loader writes over steam.exe (the original is kept as steam.back). It opens an Edge WebView2 window with phishing protection switched off and loads https://8393546939.dojiner.at/ to capture a Steam login. Extracted statically: SilentExecuter .NET binder -> HiddenAutoLauncher (.NET, 60-minute delay) -> loader -> this file, hidden with a cyclic XOR (key 8c6be0d5abe29e56) and a byte interleave in 24-byte blocks. First seen in bundles from 2026-07-25, which also carry Salat Stealer. Earlier and later builds of the same client load 7834156259.dojiner.at, 8393546939.dojiner.at and 8909451279.f1shh.at.
