What is a zero-day vulnerability?
In cybersecurity, a zero-day vulnerability refers to a vulnerability in a system or device that has been disclosed but not yet patched. The vulnerability was discovered before developers and security researchers were aware of it and could provide a patch/update.
Why are zero-day vulnerabilities dangerous?
Two main reasons: Cybercriminals can freely exploit these vulnerabilities by malware infections, potentially resulting in data loss for the victims. The systems are vulnerable for as long as the user does not update or install the patch issued by the vendor.
