Email Filter Bypass · · Live

HTML/SVG payload generator.
Sent easily via Gmail.

Upload your payload (EXE, PDF, DOCX). The generator encrypts it using RC4 + Custom Base64, hides it inside a fake Adobe/Office template, and spits out an HTML file. Bypasses email filters — seamlessly sent via Gmail. Browser-side decryption upon target execution.

Workflow

2-Step Generation Process.

The simplest and most powerful workflow to convert any executable into an evasive HTML document.

01 — Upload & Configure

Set your parameters

Drop any file into the HTML Builder. Select your preferred Format (Single, Multi-OS, or Remote), choose the Encryption Level (e.g. Stealth 1), and pick a Template like Adobe PDF. You can also configure the File Name, Display Extension, and Download Method (Save Dialog vs Direct). Optional features like "Wrap file in ZIP" and "Hide HTML source" are available.

02 — Build & Deploy

Get your payload

Click "Build & Download". The payload is encrypted and wrapped in the selected template. The Build Ready screen instantly provides your file information, active status, and dedicated Share Links for direct running or downloading. Track your views and downloads in real-time through the built-in statistics panel.

Delivery Formats

15+ Fake Templates.

Disguise your HTML file as a legitimate document viewer.

Template Extension Description Notes
Adobe Acrobat .html A realistic Adobe PDF viewer overlay demanding a click to "decrypt" the document. High trust
Microsoft Office .html Spoofs Word, Excel, or OneDrive interfaces asking the user to confirm their session. Enterprise targets
Google Drive .html Simulates a locked Google Drive file that requires user interaction to download. Cloud service trust
Dropbox .html Mimics the Dropbox file preview interface with a fake download button. File sharing trust
Execution Methods

How the payload is delivered.

The generated HTML file relies on native browser features to reconstruct the file in-memory and trigger the download, without any backend server.

blob_url
window.URL.createObjectURL(blob)  — Silently generates local download link
auto_click
anchor.click()  — Forces the browser to save the decrypted payload
in_memory
Uint8Array / ArrayBuffer  — Completely fileless decryption process
Obfuscation

Three encryption layers.

The file is securely packed inside the HTML template. Every build generates a unique JavaScript decoder structure to evade static signatures.

rc4 default

The core executable is encrypted using RC4 with a randomized hex key. The key rotates automatically per generation.

custom_b64

Instead of standard Base64, the platform generates a randomized 64-character alphabet for every build to bypass pattern recognition.

chunk_shuffle

The encrypted payload is sliced into random 60-100 character chunks, shuffled out of order, and reassembled dynamically in the browser.

Platform Features

Built for operators.

🔐

Polymorphic Encryption

The payload is encoded using 1 to 3 layers of Custom Base64 plus Chunk Shuffling and RC4. The alphabet is regenerated per build.

🎯

Standalone Execution

The generated HTML file uses purely client-side JavaScript. No connection to a C2 is needed during execution, avoiding network signatures.

🎨

Email Delivery Ready

Easily bypass email attachments filters. Send the .html payload as an attachment via Gmail or Outlook without being flagged.

📄

Unlimited Flexibility

Wrap any file type: EXE, PDF, DOCX, ZIP, MP4. The builder parses the binary and perfectly embeds it within the HTML.

🖥

Multiple Display Options

Choose your download method. Force an immediate Save As dialog, trigger a direct silent drop, or require a button click.

💾

Self-Contained Payload

No external dependencies. The generated HTML contains the full encrypted binary, the decryption routine, and the HTML template.
