We could deduce that their victims are paying,
1. They have been active since 2019, so they have been in the extortion business for many years. This kind of criminal group are organized, so with that they needed funds. If their victims are not paying, then their infrastructure might have collapsed already.
I thought about that too, but i just find it stupid to give in to blackmail, because you never know what the extortionist is going to do. Would you trust the words of a criminal who hacked into your system in the first place, i am not sure i will.
This remind me of the attack on Revolut last month. Attackers pretended to be a LE agency and requested personal information of hundreds of Revolut's high-net-worth customers and the company handed over these documents to the attacker, believing they were legitimate request from LE. What followed was extortion to the tune of $3m, however, there are no reports that Revolut paid this ransom.
True, there are no reports surfacing on companies that have paid to the cyber criminals. But maybe again, I was thinking that they could have shown the data to the victims themselves and should think of not paying, then their data will go and leaked to the dark market.
And then "A lack of response raises questions." Specially in the recent Revolut case, so maybe they did, or maybe they didn't, but we all know that when there are silence, it's usually the admittance of guilt, just saying.
