A 0-Day is a software vulnerability without an available fix, creating risk because defenders have limited time to mitigate exploitation.

Background for this topic.
0-Day describes a software vulnerability unknown to the software maker or unpatched when first exploited. Attackers can use these flaws immediately, as no official fix or signature exists to block the exploit. Such vulnerabilities often affect widely deployed software or hardware, making them valuable for targeted attacks or widespread campaigns.
Because defenders lack patches or reliable detection signatures initially, they must rely on anomaly detection, network monitoring, and threat intelligence to identify suspicious activity linked to 0-day exploits. Rapid patching once a fix is released is critical to reduce exposure. Tracking emerging 0-day threats helps prioritize defensive measures and informs risk management decisions in environments where unpatched vulnerabilities pose significant security risks.
AnyCubic has released new Kobra 2 firmware to fix a zero-day vulnerability exploited last month to print security warnings on 3D printers worldwide. [...]
Real-World Scenarios Are Sketchy But Researchers Warn: 'Assume Spyware; Update Now'Apple pushed out an emergency security update for two critical zero-day flaws that attackers are using to carry out memory corruption attacks on iPhone and iPad devices. The tech giant's latest patch addressed its third zero-day vulnerability this year.
A pair of critical bugs could open the door to complete system compromise, including access to location information, iPhone camera and mic, and messages. Rootkitted attackers could theoretically perform lateral movement to corporate networks, too.
Apple has released security updates to address several security flaws, including two vulnerabilities that it said have been actively exploited in the wild
Apple released emergency security updates to fix two iOS zero-day vulnerabilities that were exploited in attacks on iPhones. [...]
