BlueTeamSec briefing for Sunday the 27th of September 2026. No new security developments to report today, so instead we've got a story from the archives — one that rather changed everything.
Historical Archive reminds us that on the 2nd of November 1988, Cornell graduate student Robert Tappan Morris released what became the first major internet worm — accidentally crippling around six thousand machines, roughly ten percent of the internet at the time. Morris had intended to measure the size of the network, but a programming error caused infected systems to be reinfected repeatedly until they crashed. The worm exploited sendmail, finger daemon, and weak passwords, spreading through universities, research labs, and military sites. Morris became the first person convicted under the Computer Fraud and Abuse Act, and the incident led directly to the creation of CERT. Worth reading if you're interested in how a single mistake laid the foundations for the entire modern security industry.
That's everything for today. The article is the work of its original author — the analysis here was automated.
