Sudhish Kasaba Ramesh, a former Cisco engineer, was sentenced on Wednesday to two years in prison and ordered to pay a $15,000 fine. The 30-year-old accessed Cisco’s cloud infrastructure hosted on Amazon Web Services without permission on September 24, 2018, after resigning from the company five months earlier, in April 2018. Over 16,000 WebEx Teams accounts had to be shut down for roughly two weeks which resulted in Cisco having to spend around $2,400,000 in customer refunds and employee time for restoring the damage.
