What is a Zero-day exploit?

A zero-day exploit is a vulnerability in a computer system or software that is unknown to the vendor or the public.

This means that the vulnerability has not been publicly disclosed and there is no patch or workaround available from the vendor. Zero-day exploits are highly sought after by hackers and cybercriminals as they can be used to gain access to systems and data without being detected.

Zero-day exploits are often used in cyberattacks as they can allow attackers to gain access to systems before the vendor has a chance to fix the vulnerability. As a result, zero-day exploits can be very dangerous and can cause a lot of damage.

Zero-day exploits are often sold on the black market for a high price.

Some examples of recent zero-day exploits include the WannaCry ransomware attack and the Equifax data breach.

Zero-day exploits are a major concern for businesses and organisations as they can be used to gain access to sensitive data and systems. It is important for businesses to ensure that their systems are protected against zero-day exploits by using security patches and software updates.

It is also important for businesses to have a strong security posture and to have a plan in place for responding to cyberattacks.
