## The many vulnerabilities Talos discovered in SOHO and industrial wireless routers post-VPNFilter
Since the discovery of the widespread VPNFilter malware in 2018 , Cisco Talos researchers have been researching vulnerabilities in small and home office (SOHO) and industrial routers.
During that research, Talos has worked with vendors to report and mitigate these vulnerabilities, totaling 141 advisories covering 289 CVEs across multiple routers.
Talos is highlighting some of the major issues our researchers discovered over the past several years, including vulnerabilities that an attacker could mostly directly access or those an adversary could chain together to gain elevated access to the devices.
There are several Snort rules that can detect possible exploitation of the vulnerabilitie
