The Shadow Brokers group in August published ‘cyber weapons’ it claimed to be from the National Security Agency-linked Equation Group. The data dump included previous undisclosed zero-day flaws, including an exploit called BENIGNCERTAIN that could potentially be used to exploit legacy Cisco firewalls.”
