Na pierwszy rzut oka to base64, wystarczy go zdekodować (pamiętając żeby "\n" nie traktowąc literalnie tylko wyciąć)
Evil Corp, we have delivered on our promise as expected. The people of the
world who have been enslaved by you have been freed. Your financial data has
been destroyed. Any attempts to salvage it will be utterly futile. Face it: you
have been owned. We at fsociety will smile as we watch you and your dark souls
die. That means any money you owe these pigs has been forgiven by us, your
friends at fsociety. The market's opening bell this morning will be the final
death knell of Evil Corp. We hope as a new society rises from the ashes that
you will forge a better world. A world that values the free people, a world
where greed is not encouraged, a world that belongs to us again, a world
changed forever. And while you do that, remember to repeat these words:
"flag{We are fsociety, we are finally free, we are finally awake!}"

At the first glance it looks like a base64 encoding, we only need to decode it (keeping in mind to cut out "\n" characters)
Evil Corp, we have delivered on our promise as expected. The people of the
world who have been enslaved by you have been freed. Your financial data has
been destroyed. Any attempts to salvage it will be utterly futile. Face it: you
have been owned. We at fsociety will smile as we watch you and your dark souls
die. That means any money you owe these pigs has been forgiven by us, your
friends at fsociety. The market's opening bell this morning will be the final
death knell of Evil Corp. We hope as a new society rises from the ashes that
you will forge a better world. A world that values the free people, a world
where greed is not encouraged, a world that belongs to us again, a world
changed forever. And while you do that, remember to repeat these words:
"flag{We are fsociety, we are finally free, we are finally awake!}"
We have the flag and 50 points.
