Four days. Four hacks. Four Australian companies. One threat actor. But that's Qilin for you: the number one ransomware group in the world right now, with more than 100 victims claimed globally this month alone. That said, I can guarantee one of these victims is quite incapable of paying a […]

These hackers have yet to follow through on publishing the data, but if they - and I suspect they will- that's thousands more Australian medical records about to be exposed on the darkest corners of the internet. And, in this case, it may not even be any fault of the victim, but rather a […]
