Blockchain analysis firm Chainalysis has disclosed that just two groups benefited from the majority of cryptocurrency hacks that have occurred to date. Per The Wall Street Journal, the two hacking groups could have obtained as much as $1 billion in cryptocurrencies. Since bitcoin came into being, over $1.7 billion worth of cryptocurrencies are estimated to have been stolen. According to Chainalysis’ chief economist, Philip Gradwell, the two hacking groups are most likely still active.
