What Is A Zero Day Vulnerability?
A zero day vulnerability is a software or hardware flaw that is unknown to those who should be interested in mitigating the vulnerability, including the developer/vendor. Because the developer/vendor is unaware, no patch exists to correct the issue, making it an easy target for threat actors. The term “zero day” refers to the fact that developers have zero days to address and patch the vulnerability before it can be exploited.
Exploits in Network Protocols
Network protocols are a set of rules and conventions for communication between network devices. Common network protocols include TCP/IP, HTTP, FTP, and DNS. When a zero day vulnerability is discovered in these protocols, it can be particularly dangerous. These protocols are fundamental to the operation of the internet and internal networks.
Examples of Zero Day Exploits in Network Protocols
- Heartbleed (2014): A vulnerability in the OpenSSL cryptographic software library allowed attackers to read sensitive data from the memory of affected servers. This zero day exploit affected the SSL/TLS protocols, which are used to secure communications over the internet.
- EternalBlue (2017): This exploit took advantage of a vulnerability in the SMB protocol used by Windows. It was used in the WannaCry ransomware attack, which caused widespread damage by encrypting data on infected systems and demanding ransom payments.
The Impact of Zero Day Exploits
Zero day exploits can have severe consequences, including data breaches, financial loss, and damage to an organization’s reputation. These exploits are unknown to the developer/vendor. They can be used to bypass security measures and gain unauthorized access to systems and data.
Mitigating Zero Day Vulnerabilities
- Regular Updates and Patching: While zero day vulnerabilities are unknown, keeping software and systems up to date can help mitigate the risk of known vulnerabilities being exploited.
- Network Segmentation: Dividing a network into segments can limit the spread of an attack if a zero day exploit is used.
- Intrusion Detection Systems (IDS): These systems can help detect unusual activity that may indicate an exploit is being used.
- Security Awareness Training: Educating employees about the risks of zero day vulnerabilities and how to recognize potential threats can help prevent exploitation.
