Crosslinked : LinkedIn Enumeration Tool

0
25

CrossLinked is a LinkedIn enumeration tool that uses search engine scraping to collect valid employee names from an organization. This technique provides accurate results without the use of API keys, credentials, or accessing LinkedIn directly!

Install

Install the last stable release from PyPi:

pip3 install crosslinked

Or, install the most recent code from GitHub:

git clone https://github.com/m8sec/crosslinked
cd crosslinked
python3 setup install

Prerequisite

CrossLinked assumes the organization’s account naming convention has already been identified. This is required for execution and should be added to the CMD args based on your expected output. See the Naming Format and Example Usage sections below:

Naming Format

{f}.{last} = j.smith
{first.{last} = john.smith
CMP{first}{l} = CMP\johns
{f}{last}@company.com = jsmith@company.com

Search

By default, CrossLinked will use google and bing search engines to identify employees of the target organization. After execution, two files (names.txt & names.csv) will appear in the current directory, unless modified in the CMD args.

  • names.txt – List of unique user accounts in the specified format.
  • names.csv – Raw search data. See the Parse section below for more.

Example Usage

python3 crosslinked.py -f ‘{first}.{last}@domain.com’ company_name

python3 crosslinked.py -f ‘domain{f}{last}’ -t 15 -j 2 company_name

Parse

Account naming convention changed after execution and now your hitting CAPTCHA requests? No Problem!

CrossLinked v0.2.0 now includes a names.csv output file, which stores all scraping data including: first namelast namejob title, and url. This can be ingested and parsed to reformat user accounts as needed.

Example Usage

python3 crosslinked.py -f ‘{f}{last}@domain.com’ names.csv

Additional Options
