One common use of 0 day exploits is to gain unauthorized access to systems or networks. Hackers may use these exploits to bypass authentication measures, escalate privileges, or execute arbitrary code on a targeted system.
Once they have gained access, they can steal sensitive information, install malware, or carry out other malicious activities. Another way that hackers use 0 day exploits is to disrupt operations and cause damage to systems. For example, they may use these exploits to launch denial-of-service attacks, which can overwhelm a system with traffic and make it unavailable to legitimate users.
This can be particularly damaging for organizations that rely on their systems for critical operations, such as financial institutions or government agencies. In some cases, hackers may also use 0 day exploits to spread malware or ransomware. By exploiting vulnerabilities in popular software or systems, they can infect a large number of devices and networks with malicious code, leading to widespread damage and disruption.
Strategies for Defending Against 0 Day Exploits
| Strategy | Description |
|---|---|
