Tim Starks
Summary
An attacker exploited a previously unknown Cisco zero-day vulnerability in the company's SD-WAN software earlier this year to infiltrate a communications service provider and gain root-level (highest) access. Cisco has since patched the flaw, which was one of seven actively exploited zero-days in its SD-WAN software this year. Mandiant, the Google-owned cybersecurity firm, disclosed the incident, noting the attacker gained the highest level of access possible on the targeted network.
