- A former Cisco employee pleaded guilty in a San Jose federal court on Wednesday to unlawfully accessing Switchzilla's Amazon Web Services infrastructure and damaging the networking giant's cloud computing resources.
- Sudhish Kasaba Ramesh, who worked at Cisco from July 2016 to April 2018, admitted in a plea agreement with prosecutors that he had deliberately connected to Cisco's AWS-hosted systems without authorization in September 2018 – five months after leaving the manufacturer. He then proceeded to delete virtual machines powering Cisco's WebEx video-conferencing service.
