Ghost hackers: the cybersecurity mystery that nobody has solved

The article revisits the long-unsolved Shadow Brokers mystery, a group that emerged in 2016 and claimed to leak NSA-linked hacking tools.

They posted some of the alleged cyberweapons publicly, then disappeared without their identities ever being confirmed.

Despite theories about insiders or Russian intelligence, no one has been charged in connection with the leak.

The case shows how major espionage leaks can stay unattributed for years while stolen tools like EternalBlue are later reused in attacks.
