This is the BlueTeamSec briefing for Friday the 6th of November 2026. No fresh security developments today, so instead we're taking a look back at a piece of cybersecurity history.
Historical Archive takes us back to 1971, when an engineer at BBN Technologies created Creeper — the first self-replicating computer program — on ARPANET. It hopped between mainframes displaying 'I'm the Creeper: catch me if you can', which prompted Ray Tomlinson to write Reaper, the first antivirus program, to chase it down. Harmless as it was, the dynamic it established — offensive capability followed by defensive response — is still the foundation of the industry fifty-five years later.
And that's your briefing. The original article comes from the Historical Archive — the analysis here was automated as always.
