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.
Hackers Could Cause Tanks to Overfill and Disable Leak DetectionIndustrial control systems made by different manufacturers for monitoring fuel storage tanks including those used in everyday gas stations contain critical zero-days that could convert them into targets for cyberattacks that cause physical damage.
Thousands of devices remain vulnerable, US most exposed to the threat Tens of thousands of fuel storage tanks in critical infrastructure facilities remain vulnerable to zero-day attacks due to buggy Automatic Tank Gauge systems from multiple vendors, say infosec researchers. …
