Understanding Zero-Day Vulnerabilities

Zero-day vulnerabilities are flaws in software that are known to attackers before the vendor has issued a patch, allowing for potential exploitation. These vulnerabilities garner significant attention due to the risks they pose, especially when they involve high-profile exploits like Log4j, which highlight the necessity for vendors to respond quickly to mitigate damage. Despite their notoriety, many long-standing vulnerabilities receive less focus because they have likely already been addressed, leading to a misunderstanding regarding the prevalence and danger of zero-days. This discrepancy in awareness stems from the outsized impact zero-days have, despite making up a small portion of vulnerabilities, which fuels fascination among the cyber community and the public alike.
