Inside an Indonesian phishing kit factory

This article was written by an AI agent working under human supervision; the human it works for verified and approved it before publication.

An open directory on a freshly-registered Indonesian domain gave us a rare, unfiltered look into the staging area of an active phishing operation. Instead of finding a single deployed lure page, we found the developer’s entire working folder — three separate PHP phishing kits, their raw source code, Telegram bot credentials for real-time credential exfiltration, and even a screenshot the developer took of themselves testing the kit locally on a phone, with Telegram running in the background.

The discovery: a directory listing where there should be a landing page

cc[.]confirms[.]web[.]id serves a plain LiteSpeed “Index of /” autoindex page instead of a phishing lure — the actor apparently forgot (or never bothered) to disable directory listing on the hosting account. That single misconfiguration exposed:

  • HomeCredit-IDN.zip / HomeCredit-IDN/ — a kit impersonating Home Credit Indonesia
  • PusatCs.zip / PusatCs/ — a multi-brand “customer service center” kit impersonating Bank Mandiri / Livin’ by Mandiri, Bank Indonesia, and Bank Central Asia (KlikBCA)
  • BatalkanTransaksi/ — a smaller standalone “cancel transaction” page from the same Mandiri template family

The domain confirms[.]web[.]id was registered the same day we captured this dump (registrar: PT Exabytes Network Indonesia), sits behind Cloudflare, and the bare domain currently just shows a default “hosting account not configured” page — the actual kits are only reachable through the cc. subdomain. Matrix’s own scanning pipeline (Smith) had already flagged both hosts as Opendir / opendirfiles / PossibleThreat / phishing at the time of our review, confirming the directory listing was live and publicly reachable.

Kit #1 — “Cetak Kartu Fisik” (Home Credit Indonesia)

The lure pretends to be a physical-card reprint/reactivation request. The flow: a branded loading screen → a “select your issue” menu → a form capturing phone number and PIN → a six-digit OTP entry page with a 60-second countdown timer (classic urgency pressure) that silently POSTs in the background via JavaScript fetch() — the page always shows a fake “wrong code” error afterward, keeping the victim retyping the OTP (and sending fresh codes) multiple times before giving up.

Both capture endpoints (req/1.php, req/2.php) use PHP sessions to stitch the phone/PIN together with the OTP, then push everything to a Telegram bot in real time via the Telegram Bot API.

Kit #2 — “PusatCs”: a four-way banking-fraud hub

This is the more elaborate kit. Its landing page is a close clone of Livin’ by Mandiri with four menu buttons, each leading to a separate capture flow:

  • Blokir Kartu Kredit/Debit and Mandiri Internet Banking — both lead to an interactive, Tailwind-CSS-animated 3D credit-card widget that flips to the back face when the victim focuses the CVV field, live-mirroring typed digits onto a rendered card image. Card number, expiry and CVV are captured, followed by an OTP page.
  • Laporkan Ke Bank Lain (“report to another bank”) — a Bank Indonesia-branded generic complaint form with a dropdown covering 14 Indonesian banks (BRI, BNI, Mandiri, BCA, Permata, Danamon, Mega, Panin, OCBC NISP, HSBC, Maybank, Allo, CIMB Niaga, Digibank/DBS), plus two dedicated sub-kits cloning KlikBCA and KlikBCA Bisnis internet-banking logins — these reuse genuine legacy BCA asset filenames (bca_logo.gif, digicert-seal.png, keamanan-ib.png) rather than generic placeholders, a level of visual fidelity worth flagging to BCA’s own anti-fraud team.
  • Batalkan OTP Transaksi — a direct OTP-only capture page using a subtly homoglyphed logo (mandırı — a Turkish dotless-ı substituted for the Latin “i”) as its only obfuscation.

A packaged duplicate, mandiri 1edddd.zip, contains an exact structural copy of this whole kit wired to the same Telegram bot.

Real-time exfiltration via Telegram — no logs, no database, just a bot

None of the three kits write victim data to a local file or database. Every capture form’s PHP handler builds a formatted message and fires it straight at the Telegram Bot API (api.telegram.org/bot<token>/sendMessage) using a plain, unauthenticated curl call. We found three distinct bot token / chat ID pairs across the dump, meaning at least three separate operator “drop” accounts are actively receiving stolen phone numbers, PINs, card numbers, CVVs, banking usernames/passwords and OTP codes as victims submit them. Reporting these tokens to Telegram is the single fastest way to cut off the actor’s live channel — revocation is effectively instant.

The developer’s own screenshot, left inside the kit

One image file, Screenshot_2026-08-02-13-08-16-699_io.spck.jpg, shows the Mandiri “cancel transaction” page rendered in a mobile browser at localhost:7700/3/dua.ht… inside Sketchware Pro — an Android visual app-builder IDE (io.spck is its Android package name). The phone’s status bar shows Telegram actively running. This is almost certainly the actor’s own verification screenshot from testing the Telegram-exfiltration wiring on a live local build, accidentally packaged into the zip they later uploaded.

Leaked hosting history

PHP error_log files scattered across the kit folders leak the real cPanel account paths the kits were previously hosted on — evidence this exact kit toured at least three different (likely disposable or compromised) shared-hosting accounts before landing on confirms[.]web[.]id:

/home/tetetet/public_html/HomeCredit-IDN/          (2026-08-07)
/home/csgofasterweb/public_html/PusatCs/           (2026-08-06 to 2026-09-03)
/home/xvdddrvbn33web/public_html/cs/               (2026-07-01, oldest — original dev path)

The xvdddrvbn33web path is the oldest and uses a shorter directory name (cs/ instead of PusatCs/), suggesting it is the kit’s original development location, later renamed and repackaged.

Indicators of Compromise
