Life isn't fair guys ! Can I take any action?

So there's a girl in my class no never studied or worked hard but she has a relative's friend in an MNC through that friend, she paid 50k + 2 months salary to him to get into that MNC through backdoor. She joined few days ago only her ctc is almost 9lpa. Most of the hardworking people in our class got way less package than her. What do you guys think, can I mail to the company saying there's been backdoor jobs like that ? She also has a very bad personality and now started to look down on many of her friends coz they are unemployed or earn less and makes jokes about it as well (I'm one of her friends)... I'm just sharing it here

TLDR : Classmate got a job through backdoor and now has a better package than everyone of us. And started to behave cocky
