US military’s email domains end in .mil (their top-level domain). The top-level domain for the country Mali (which has ties to Russia these days) ends in .ml. Do you see the problem?

Of course, some smart sysop could have easily spotted this decades ago – as did Johannes Zuurbier, a Dutch entrepreneur who currently (but not for much longer) manages Mail’s country domain. Cyber security becomes increasingly complex (especially with the advent of AI), but it truly starts with the basics.
