Zero-day Exploits

Zero-day exploits are valuable to hackers because they can be used to gain access to systems that have not yet been patched. Hackers can use these exploits to steal sensitive data, install malware, or take control of a system. The value of a zero-day exploit depends on:

• How widely the software is used
• How difficult the exploit is to discover
• How valuable the target is

Example

For example, in 2017, a group of hackers used a zero-day exploit in Microsoft Word to install malware on millions of computers worldwide. The exploit was valuable because it targeted a widely used software and was difficult to detect. The group was able to use the exploit for several months before it was discovered and patched.

Black Market

Hackers can also sell zero-day exploits on the black market, where they can fetch high prices from other hackers or governments. Governments may use these exploits for intelligence gathering, cyber espionage, or cyber warfare. Some governments have dedicated teams of hackers who search for and develop zero-day exploits.

Overall, zero-day exploits are valuable to hackers because they provide a way to bypass security measures and gain access to systems that would otherwise be protected.
