The SQL Slammer Virus, also known as the Sapphire Virus, is malware in the form of a worm that caused a Denial of Service on many internet hosts in 2003, and caused thousands of network outages and even dramatically slow down Internet traffic! The worm spread rapidly, infecting the majority of its 75,000 victims within ten minutes. This worm exploited a vulnerability in Microsoft’s SQL Server.
Social isolation is the 2020 solution to flatten the curve on Coronavirus infections. In 2003 preventing the spread of SQL Slammer required network Isolation (blocking TCP 1434 – SQL’s communications port). However, as witnessed by the COVID-like map from 2003, due to the speed of computer infections, network isolation couldn’t be put in place fast enough to stop the spread of SQL Slammer. Whether the world has learned enough to put social isolation in place quickly enough to slow and stop the spread of COVID19 remains to be seen.
