Many different groups of people carry out zero-day attacks, including:
Hacktivists: People who seek to hack systems to advance a political cause or agenda
Corporate Hackers: Hackers seeking to gain information about a competitor
For-Profit Hackers: People who find vulnerabilities to sell to companies (but who have no intention of exploiting the vulnerability themselves)
How a Zero-Day Attack Works
Although each attack is different, most attacks usually work like this:
Step 1: Your developers create a system. This system qatar whatsapp number data contains a zero-day vulnerability that the developers are unaware of.
Step 2 : Once the system is up and running, the hacker (sometimes called a “threat actor” or “malicious actor”) discovers a vulnerability in the system.
Step 3 : The hacker writes and executes malicious code to exploit the vulnerability and penetrate the system.
Step 4 : The public or developers notice a serious problem, and the developers fix the problem with a patch.
Sometimes, the hacker who discovers your zero-day threat and the hacker who attacks your system are different people.
Some hackers sell information to other hackers through the black market. The black market exists on the dark web , a section of the internet that you can't reach with search engines like Google, Yahoo, and Bing. People access the dark web through anonymous browsers like Tor.
Some cybersecurity companies are also looking for exploits to sell that information to system owners.
These companies sell that data on either “white” or “gray” markets (although the distinctions between white, gray, and black markets vary depending on local cybersecurity laws).
