U.Ok. NCSC Warns of SHOE RACK and UMBRELLA STAND Malware Focusing on Fortinet Units
The event comes because the U.Ok. Nationwide Cyber Safety Centre (NCSC) revealed two totally different malware households dubbed SHOE RACK and UMBRELLA STAND which have been discovered focusing on FortiGate 100D collection firewalls made by Fortinet.
