Zero Day Vulnerability

Zero Day Vulnerability

Context: Another zero-day vulnerability has hit Google Chrome, causing alarm among users and cyber experts.

About:

• A ZDV (zero-day vulnerability) is a system or software vulnerability that is unknown to the vendor and lacks any available patch or means of mitigation at the time of discovery.
• The term \'ZDV\' specifically refers to the flaw itself, highlighting its undisclosed and unaddressed nature.
• A zero-day attack occurs when threat actors exploit a ZDV shortly after its discovery, with zero days between identifying the vulnerability and launching the initial attack.
• A zero-day exploit refers to the specific method or technique employed by hackers to capitalize on a ZDV, often utilizing malware to execute the attack.
• The development and release of malware targeting the ZDV mark the occurrence of a zero-day attack, demonstrating the immediate threat posed by these vulnerabilities.
• ZDVs pose a significant risk to users due to the following reasons:
• Cybercriminals rush to exploit these vulnerabilities to profit from their malicious schemes.
• Systems remain vulnerable and exposed until a patch is released by the vendor to address the ZDV.
• Once a ZDV becomes publicly known and a patch is eventually issued by security researchers or software developers, it transitions from a zero-day vulnerability to an \'n-day\' or \'one-day\' vulnerability
