​? OSINT. Some useful tips from sector035.

• I will share some tips that sector035 posted on his blog yesterday. I hope it will be useful, though quite specific:

 Tip #1: Using the desktop version of Telegram, you can export chat messages of groups that you are a member of, and even public groups without joining them. After exporting chat messages, you can create a list of names in various ways. If you use macOS or #Linux, the easiest way is to go to the downloads folder and use the command line to create a list of unique usernames, for example:

cat messages* | grep -A1 "from_name" | cut -f1 -d "<" | sort -u > members.txt

• We will not be able to find out the names and ids of Telegram accounts, but we will be able to parse the display names.

 Tip #2: A list of websites with information about the building, such as height, number of floors, location and more:

• The above resources will be very useful for GEOINT, be sure to save to favorites.

➖ Tip #3: To view the list of Wordpress site users, it is enough to change the URL to the following:

{site}/wp-json/wp/v2/users

•  This will return a JSON dump for everyone who has an account on a particular site, and may reveal interesting information. If there are too many results, add pagination using per_page:

{site}/wp-json/wp/v2/posts/?per_page=100&page=1

• This advice has been well known for many years in the #OSINT community, but many people are just starting to work in this area and this information will be very useful.
