Agencies in the U.S. and United Kingdom this week released an advisory detailing tactics used to exploit a known vulnerability in Cisco routers to deploy malware and recommendations to protect vulnerable Cisco devices.
“This joint U.S. and U.K. advisory cites with high confidence that elements of the Russian Military Intelligence Service have been exploiting a known vulnerability in Cisco network routers since at least 2017,” said John Riggi, AHA’s national advisor for cybersecurity and risk. “Like the SolarWinds compromise, this highlights the ongoing targeting of strategic third-party network technology, which is widely present in government and private-sector networks. These strategic cyberattacks on the technology supply chain may give the Russian government a basis to conduct covert reconnaissance of sensitive networks, steal data and/or pre-position itself for future destructive cyberattacks. It is strongly recommended that the patch for vulnerability CVE-2017-6742 be implemented as soon as possible.”
