Who needs Netflix when you have real-life cyber espionage thrillers like Mustang Panda’s latest escapade? This hacking group is on a mission to outdo the best spy novels, complete with stolen certificates, kernel-mode rootkits, and a backdoor that’s sneakier than a cat burglar. It’s like Mission Impossible, but with fewer explosions and more computer screens. Can someone get Tom Cruise to play the hacker in this one?
