Prerequisites

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

{first.{last}           = john.smith
CMP\{first}{l}          = CMP\johns
{f}{last}@company.com   = [e-mail]

🦖 Still Stuck? Metadata is always a good place to check for hidden information such as account naming convention. see PyMeta for more.

Advanced Formatting

💥 New Feature 💥

To be compatible with alternate naming conventions CrossLinked allows users to control the index position of the name extracted from search text. Should the name not be long enough, or errors encountered with the search string, CrossLinked will revert back to its default format.

Note: the search string array starts at 0. Negative numbers can also be used to count backwards from the last value.

# Default output
python3 crosslinked.py -f '{first}.{last}@company.com' Company
John David Smith = [e-mail]

# Use the second-to-last name as "last"
python3 crosslinked.py -f '{0:first}.{-2:last}@company.com' Company
John David Smith    = [e-mail]
Jane Doe            = [e-mail]

# Use the second item in the array as "last"
python3 crosslinked.py -f '{first}.{1:last}@company.com' Company
John David Smith    = [e-mail]
Jane Doe            = [e-mail]

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

⚠️ For best results, use the company name as it appears on LinkedIn "Target Company" not the domain name.

Screenshots

Parse

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

CrossLinked includes a names.csv output file, which stores all scraping data including: name, job 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

Proxy Rotation

The latest version of CrossLinked provides proxy support to rotate source addresses. Users can input a single proxy with --proxy 127.0.0.1:8080 or use multiple via --proxy-file proxies.txt.

> cat proxies.txt
127.0.0.1:8080
socks4://111.111.111.111
socks5://222.222.222.222

> python3 crosslinked.py --proxy-file proxies.txt -f '{first}.{last}@company.com' -t 10 "Company"

⚠️ HTTP/S proxies can be added by IP:Port notation. However, socks proxies will require a socks4:// or socks5:// prefix.*
