OSINT Tool: Generate username lists from companies on LinkedIn.
This is a pure web-scraper, no API key required. You use your valid LinkedIn username and password to login, it will create several lists of possible username formats for all employees of a company you point it at.
Use an account with a lot of connections, otherwise you'll get crappy results. Adding a couple connections at the target company should help - this tool will work up to third degree connections. Note that LinkedIn will cap search results to 1000 employees max. You can use the features '--geoblast' or '--keywords' to bypass this limit. Look at help below for more details.
WARNING: LinkedIn has recently (Sept 2020) been hitting li2u users with the monthly commercial search limit. It's a bit mysterious as to when/why this happens. When you hit the limit, you won't be able to search again until the 1st of the month. If you know of a workaround, please let me know.
Here's what you get:
- first.last.txt: Usernames like Joe.Schmoe
- f.last.txt: Usernames like J.Schmoe
- flast.txt: Usernames like JSchmoe
- firstl.txt: Usernames like JoeS
- first.txt Usernames like Joe
- lastf.txt Usernames like SchmoeJ
- rawnames.txt: Full name like Joe Schmoe
Optionally, the tool will append @domain.xxx to the usernames.
You'll need to provide the tool with LinkedIn's company name. You can find that by looking at the URL for the company's page. It should look something like https://linkedin.com/company/uber-com. It may or may not be as simple as the exact name of the company.
Here's an example to pull all employees of Uber:
$ python linkedin2username.py myname@email.com uber-com
Here's an example to pull a shorter list and append the domain name @uber.com to them:
$ python linkedin2username.py myname@email.com uber-com -d 5 -n 'uber.com'
usage: linkedin2username.py [-h] [-p PASSWORD] [-n DOMAIN] [-d DEPTH]
[-s SLEEP]

VERIFICATION.
-k KEYWORDS, --keywords KEYWORDS
Filter results by a a list of command separated
keywords. Will do a separate loop for each keyword,
potentially bypassing the 1,000 record limit.
[example: "-k 'sales,human resources,information
technology']
-g, --geoblast Attempts to bypass the 1,000 record search limit by
running multiple searches split across geographic
regions.
Sometimes LinkedIn does weird stuff or returns weird results. Sometimes it doesn't like you logging in from new locations. If something looks off, run the tool once or twice more. If it still isn't working, please open an issue.
