The act of sharing download files or download links of cracked software (which are not freely available) on your website, and the act of earning money off it, in my opinion, are haram, unless you have the permission (to share their software via download files or help share via download links) of the companies/publishers who develop and sell those software.
Quran verse 5:38 prohibits stealing clearly. Obtaining a software product illegally without paying the price its owner asks for it, or sharing its files, or sharing download links to it can also be considered as a type of stealing, because it is an act that is against the will of its developer/publisher.
Imagine that you are running a software company, developing and selling useful software for people. If you and hundreds of your staff spent millions of money, thousands of development hours in developing a software, and then put the finished product for sale, so that you and your staff can provide for their families, would you like your software to be cracked and shared freely?
Please don't do it. Devil continuously keeps whispering to do haram things that will bring easy money. We shall resist that.
