[Audio] What are zero-day exploits?. What are zero-day exploits?.

[Audio] Zero-Day • The term "zero-day" refers to the fact that the vulnerability is not known to the software vendor or the public, so there is no patch or fix available to address it. This makes zero-day exploits particularly dangerous because they can be used by attackers to gain access to systems and networks without being detected..

[Audio] Zero-day exploits are often sold on the black market or used by advanced persistent threat (APT) groups, which are sophisticated cyber attackers that target specific organizations or industries. APT groups use zero-day exploits to gain a foothold in a target's network and move laterally to steal sensitive data or conduct other malicious activities..

[Audio] 1.Discovery: The vulnerability is discovered by a security researcher, an attacker, or someone else who has access to the software code. At this stage, the vulnerability is not yet publicly known. 2.Exploitation: The attacker develops an exploit that takes advantage of the vulnerability. This exploit can be used to compromise a system, steal data, or carry out other malicious activities..

[Audio] 3. Deployment: The attacker deploys the exploit in a targeted attack against a specific victim or organization. This can be done through various means, such as a phishing email, a malicious website, or a compromised software update. 4. Detection: The attack is detected by security researchers, the victim organization, or other parties. This can happen through various means, such as intrusion detection systems, security software, or manual analysis of network traffic..

[Audio] 5. Patching: The software vendor releases a patch or update to fix the vulnerability. This can be done through various means, such as a software update, a hotfix, or a workaround. 6. Disclosure: The vulnerability is publicly disclosed, either by the software vendor or by the security researcher who discovered it. This can lead to increased awareness of the vulnerability and help other organizations protect themselves from similar attacks..
