    A blend of humor and quest for fame revealed. Money is one thing but showing off who’s the best among ransomware groups is another. Letting the world know must be so gratifying. Funny or not, quite a nerve it is to fill a complaint about the victim when you have in mind the destruction behind. Jerks, smart jerks often, with a kid’s mentality, always, totally disconnected from the basics of human relationships.

      “with a kid’s mentality, always, totally disconnected from the basics of human relationships.”?

      What do you know, seriously? This last statement is totally baseless and pure speculation.

      What’s more childish is not reporting when you have been breached, as a company, it’s their legal obligation to inform their customers and stakeholders of this type of thing.

        Showing up, the quest for fame is relevant of a kid’s mentality, a total lack of compassion is relevant of a disconnection from the very basics of humanity. Of course we have hi-tech attackers who only comply to the latter. To summarize : always jerks and most of the time assholes who like to show up their exploits like others their prison tickets once they get liberated from jail.
        Not reporting when you have been breached is not childish but irresponsible, yet understandable. To understand is one thing, to agree is another. What would each of us do if confronted to such situations ?
