What is a Zero Day Exploit? You need to know

If security vulnerabilities occur in software or hardware, they are often exploited by so-called black hat hackers. There are now numerous attacks with which they can obtain data or gain unauthorized access to systems. One of these is the zero day exploit.

What's behind the Zero Day Exploit

As software becomes more complex, security vulnerabilities also occur more frequently. These "exploits" can be exploited by attackers to gain unauthorized information or access to a system. If a security hole is discovered and exploited on the same day, it is a zero day exploit. The meaning of the name comes from the fact that not a day passes between the disclosure and the exploitation of the gap. Thus, software developers cannot close this gap in time.

1. A Zero Day Exploit consists of three steps.
2. In the first step, a developer programs software that accidentally contains a vulnerability.
3. Afterwards, a hacker finds this vulnerability and also learns how he can exploit it to get into the system or capture information. To do this, he usually writes his own code, which is also called an exploit. Nicht immer wird dieser auch vom Entwickler selbst verwendet.
4. Abschließend wird auch das Unternehmen auf die Schwachstelle aufmerksam. Dies kann durch die Entwickler selbst, aber auch durch Hinweise von Nutzern geschehen. Die Softwareentwickler versuchen nun, die Lücke so schnell wie möglich zu schließen.
