How does Malicious hackers harm your Network?

Over the years, the term hacking has taken on a negative connotation, which is not surprising. Hacking is often used for malicious purposes, such as a way to identify and exploit system vulnerabilities to gain unauthorized access or security threats, resulting in data loss or financial loss and other serious damage.

Hacking skills can be used for more than just malicious acts. Hackers are often hired by security forces to use their skills to improve their security and keep intruders out of their systems, servers, networks, or other software.

More characteristics and information about hacking

While a certified ethical hacker in Dubai does not have to perform certain actions during a break-in, there are five main stages, including scouting, scanning, gaining access, maintaining access, and clearing tracks.

Hacking phases:

The first step in hacking is Intelligence, also known as tracing or information gathering. At this stage, the hacker must collect as much information as possible. Information is collected about the network, the host and the people involved.

The second scan phrase includes three types of scan: port scan, vulnerability scan, network mapping.

The third phase of gaining access reflects the phase when the hacker enters the target system or network. Once a hacker has infiltrated the system, administrator permission is required to install programs and tools needed to customize or hide data.

After gaining access, the phrase “Supportive access” follows. An attacker who has compromised a system may only want to show that it is vulnerable, or he may also want to keep or use an unauthorized connection in the background. To do this, hackers often use malware such as Trojans, rootkits, or other malware. Access must be maintained until tasks are completed.

The last step is to clear the track. A malicious hacker does not want to be caught, so it is necessary to clear all evidence and traces that may lead to him. This stage consists of modifying, corrupting and / or deleting logs, registry values, applications used, etc. Even if each hacker chooses his own hacking phases, these are the five basic recommended and most frequently used steps.

The most common types of attacks

It is worth noting that there are different types of attacks. Attacks include operating system attacks, configuration modifications, application layer attacks, and compressed code attacks. Let’s talk a little more about each attack. A certified ethical hacker in Abu Dhabi helps to prevent these attacks.

Operating system attacks refer to the detection and exploitation of vulnerabilities and weaknesses in the operating system. For example, an unpatched system or a buffer overflow.

Configuration modification attacks are often the result of misconfiguration of a deployed device or system. These attacks target databases, servers, software, or networks. Application Lever attacks target programs and applications. Some of the examples are SQL injection, cross-site scripting and similar attacks. Code compression attacks are performed using default components or off-the-shelf components if the code or script is not configured properly. These are the main types of attacks that are usually performed due to weaknesses, vulnerabilities, misconfiguration and other errors in systems, networks, software or codes / scripts.
