Cracked version of Burp Suite Professional, is it safe?

> A crack is as trustworthy as the person you are obtaining it from… so not at all trustworthy. - [source](https://www.reddit.com/r/hacking/comments/vf7ym8/comment/icu7jex/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button)

I kind of agree with the above quoted reply of a thread in Reddit.

Yesterday I tried out one of the cracked version of Burp Suite Pro
that I found on Telegram (heck, they even got the [@burpsuite](https://t.me/burpsuite)
handle). They provide a zip file which after opening contains at least
the following important stuff: (1) Burp Suite Pro jar file, and (2) the keygen/loader jar file.

Upon dissecting the loader jar file using [jadx-gui](https://github.com/skylot/jadx), I can
confirm that it is safe. It's not even obfuscated and rather simple and easy to check.
If I were to use this software, I think I wouldn't mind checking the loader code every
time I update it. But, I have yet confirmed that the Burp Suite Pro jar file that
they ship in the zip file is also safe. By safe, I mean no backdoor or anything suspicious.
The mechanism they use to bypass the license check is quite interesting. I may try to replicate
they it in the future, just for fun ;)

PS: I don't advocate for piracy, but I believe it's a fun and thrilling thing to do
