What Is The Zero Day Vulnerability| Shadow Cyber Security
A zero day vulnerability is a vulnerability in a system or device that has been disclosed but is not yet patched. An exploit that attacks a zero day vulnerability is called day exploit.
The zero day exploit abused a local privilege vulnerability in Microsoft Windows to run arbitrary code and install applications and view and change the data on compromised applications.The attack was identified and reported to the Microsoft Security Response Center a patch was developed and rolled out.
Examples of zero day attacks
Stuxnet: This malicious computer worm targeted computers used for manufacturing purposes in several countries, including Iran,Indonesia and India.
The primary target was Iran's uranium enrichment plants with the intention of disrupting the country's nuclear program.
What is a zero day attack in relation to cyber security?
A Zero Day Exploit is the technique or tactic a malicious actor uses to leverage the vulnerability to attack a system. A Zero Day Attack occurs when a hacker release malware to exploit the software vulnerability before the software developer has patched the flaw.
How zero day attack are identified ?
In most cases, hackers use code to exploit zero day. Sometimes it is discovered by an individual when the program behabes suspiciously ot the developer himself may recognize the vulnerability.
What are the most recent zero day attacks?
Notable zero day attacks identified by HC3 includes a 2010 attack on an Iran nuclear program that successfully caused centrifuges to self destruct and the 2021 SonicWall zero day ransomware attack in which threat actors exploited a vulnerability and subsequently deployed FivHands ransomware.
How does a zero day vulnerability differ from malware?
In most cases, a zero . day exploit is packaged as malware. Zero day exploits are often highly successful until they become widely known and either the software is patched or other security measures are put in place to successful identity and black the exploit.
Do zero days have CVE?
The new zero day confirmed as being under active exploit(CVE-2022-41033)is an EoP vulnerability in the Windows COM+Event System Service. It carries a 7.8 CVSS score.
What is Log4j vulnerability?
The Log4j issue is a type of remote code execution vulnerability and a very serious one that allows an attacker to drop malware or ransomware on a target system.In turn, lead to complete compromise of the network and the theft of sensitive information as well as the possibility of sabotage.
Is zero day exploit a social engineering attack?
Sometimes attackers can gain access to the system just by using a zero day exploit. If they can't they'll try and trick someone into letting them inside.
Cyber attackers often do this through social engineering, techniques that play on human psychology to trick them into letting their guard down.
What are the four main types of vulnerability?
According to the different types of losses, the vulnerability can be defined as economic vulnerability, Physical vulnerability and environment vulnerability.
Can zero day detached?
Zero Day Attack by definition is difficult to detect with traditional cyber security practices. Attackers spend years to develop the skill of finding such vulnerability,hence you need to be more sophisticated in detecting them even before the attackers.
Which of the following ids the best way to mitigate zero day exploits?
Preventative security,the number one way to mitigate the damage from any attack on your system is to prevent it from happening in the first place. Maintaining a good firewall and up to date antivirus is the best step you can take to ensure the security of your system.
How do hackers exploit vulnerability?
Exploitation is a piece of programmed software or script which can allow hackers to take control over a system, exploiting its vulnerability. Hackers normally use vulnerability scanners like Nessus, Nexpose, OpenVAS,etc to find these vulnerabilities.
Who carries out zero day attacks?
Malicious actors who carry out zero day attacks fall into different categories, depending in their motivation, For example:-
- Cyber Criminals- Hackers whose motivation is usually financial gain.
- Corporate espionage- Hackers who spy on companies to gain information about them.
-Hacktivists-
Hackers motivated by a political or social cause who want the attacks to be visible to draw attention to their cause.
-Cyberwarfare- Countries or political actors spying on or attacking another country's cyber infrastructure.

A zero day hack can exploit vulnerabilities in a variety of systems, including:-
1. Internet of things
2. Hardware And firmware
3.Open source components
4. Office applications
5. Web browsers
6. Operating systems.
