I started to write a comment about how low they probably were able to bribe people for but found this article [0] which put the number higher than I expected:

> One of the core LAPSUS$ members who used the nicknames “Oklaqq” and “WhiteDoxbin” posted recruitment messages to Reddit last year, offering employees at AT&T, T-Mobile and Verizon up to $20,000 a week to perform “inside jobs.”

That said, this is but one instance and I'd imagine that on the whole they are able to bribe people at much lower numbers. See also: how little it takes to bribe some government officials.
