From the article:

> Activity 2: Take five less fortunate children to Dominos, Pizza Hut or KFC for a treat, take pictures and videos, and post them on social media.

It's one of the required activities to allegedly get the decryption key.

Judging by the English it probably is where the authors of the malware are from. It's probably a cultural disconnect issue but there are places in South America, Asia and Africa where you could do this and it would be a big deal to those kids. Often people bring boxes of chocolate in their luggage to hand out to children when they vist these sort of places.

In the US places like that exist as well but under 13s aren't just hanging around to invite out and feed.

While the action may look creepy and KFCs definitely not the healthiest choice, it is donating. You are donating food to someone hungry.
