Long time no blog. During a recent OSINT investigation, I found that I needed to pull all domains found from my query on crt.sh. The problem I had, however, was that the results weren’t all that usable without a lot of copying, pasting, and cleaning.
To address this problem, and to save time in the future, I created a Jupyter Notebook to programmatically query the crt.sh website, dump the results into a pandas data frame (thinking that I’ll want to further enrich the data at a later date), and then printing out the unique list of results to the screen.
Hopefully, you can get some use from it. Until next time!
