INSPIRED FROM OffensiveRust (want to explore weaponization of Rust, check this repo out - https://github.com/trickster0/OffensiveRust) and also a lot FROM THE BOOK - BLACK HAT WITH RUST

For Educational Purposes Only. (or is it? :p)

Name DocBot - inspired from matrix sentinel (also called machine, docbot)

DOCBOT is a swift, multithreaded PDF password cracking tool crafted in Rust. It supports dictionary attacks based on wordlists, as well as brute-forcing techniques like date, number range, and alphanumeric combinations. Additionally, it includes a personalized query builder for defining specific password formats.

• Custom Query Builder: Allows for the creation of personalized queries such as STRING{69-420}, which generates and utilizes a wordlist with the entire specified number range.
• Date Bruteforce: Enables bruteforce attempts for all 365 days of a given year in DDMMYYYY format, commonly encountered in PDF password formats.
• Number Bruteforce: Supports bruteforce attacks within a specified number range, e.g., 5000-100000.
• Default Bruteforce: Allows the specification of maximum and optionally minimum password lengths for a search. All passwords within the defined length range (from 4 up to the specified maximum) consisting of letters and numbers (a-zA-Z0-9) will be attempted.
• Fast: Achieves speeds of approximately 50k-100k+ passwords per second, utilizing all available CPU cores.

Install with cargo:

$ cargo install --git https://github.com/akhilsharma90/docbot.git

Install Rust/Cargo

Prerequisites:

• Git
• Rust
• Cargo (Automatically installed when installing Rust)
• A C linker (Only for Linux, generally comes pre-installed)

$ git clone https://github.com/akhilsharma90/docbot.git
$ cd docbot/
$ cargo build --release

The first command clones this repository into your local machine and the last two commands enters the directory and builds the source in release mode.

Get a list of all the arguments:

$ docbot --help

Start a dictionary attack with a wordlist:

$ docbot -f encrypted.pdf wordlist rockyou.txt

Bruteforce number ranges for the password:

$ docbot -f encrypted.pdf range 1000 9999

Bruteforce all dates in a span (inclusive in both ends) of years for the password in DDMMYYYY format:

$ docbot -f encrypted.pdf date 1900 2000

Bruteforce arbitrary strings of length 4-8:

$ docbot -f encrypted.pdf default-query --max-length 8

Bruteforce arbitrary strings of length 3:

$ docbot -f encrypted.pdf default-query --max-length 3 --min-length 3

Build a custom query to generate a wordlist: (useful when you know the password format)

$ docbot -f encrypted.pdf custom-query ALICE{1000-9999}

$ docbot -f encrypted.pdf custom-query DOC-ID{0-99}-FILE

Enable preceding zeros for custom queries: (which would make {10-5000} to {0010-5000} matching the end range's digits)

$ docbot -f encrypted.pdf custom-query ALICE{10-9999} --add-preceding-zeros
