Cisco warns of attacks on network routers, firewalls
Cisco’s Talos security intelligence group issued a warning today about an uptick in highly sophisticated attacks on network infrastructure including routers and firewalls.
The Cisco warning piggybacks a similar joint warning issued today from The UK National Cyber Security Centre (NCSC), the US National Security Agency (NSA), US Cybersecurity and Infrastructure Security Agency (CISA) and US Federal Bureau of Investigation (FBI) that noted an uptick in threats in part utilizing an exploit that first came to light in 2017. That exploit targeted an SNMP vulnerability in Cisco routers that the vendor patched in 2017.
