Welcome to Zero-day, a newsletter for all things security and privacy.

Cybersecurity is an interminable cat and mouse battle between adversaries and defenders, a long dance where both parties continue to evolve with one another. It’s an arms race that knows no end.

With Zero-day, the aim is to chronicle the most important security-related events, document the developments and technologies that shed new light on criminal hackers and threat actors who prey on businesses and critical infrastructure that impact the average person, and the steps taken by the defenders to tackle such attacks and take down cybercrime syndicates.
