There is no doubt that a cyberattacks is a horrible threat that faces companies, it targets computer information systems, infrastructures, computer networks or personal computer devices, using various methods to steal, change or destroy data or information systems.
Common Types of Cyberattacks
1- Denial of Service Attacks (DoS)
Attackers send high volumes of data or traffic through the network until the network becomes overloaded and can no longer function, they attack overwhelms a system’s resources so that it cannot respond to service requests.
In some instances, these DoS attacks are performed by many computers at the same time. This scenario of attack is known as a Distributed Denial-of-Service Attack (DDoS). This type of attack can be even more difficult to overcome due to the attacker appearing from many different IP addresses around the world simultaneously, making determining the source of the attack even more difficult for network administrators.
2- man-in-the-middle attacks (MitM)
A MitM attack occurs when a hacker inserts itself between the communications of a client and a server. Information is obtained from the end user and the entity the user is communicating with by impersonating the endpoints in an online information exchange.
3- Malware attack
Software programs designed to damage or do unwanted actions on a computer. It can attach itself to legitimate code and propagate; it can lurk in useful applications or replicate itself across the Internet. the most common examples of malware include: (Macro viruses, File infectors, System or boot-record infectors, Polymorphic viruses, Stealth viruses, Trojans, Logic bombs, Worms, Droppers, Ransomware).
shortly, a Phishing attack is sending emails that appear to be from trusted sources with the goal of gaining personal information or influencing users to do something. It could involve an attachment that loads malware onto your computer. It could also be a link to an illegitimate website that can trick you into downloading malware or handing over your personal information.
One of the simplest ways that a hacker can conduct a spear phishing attack is email spoofing, which is when the information in the From section of the email is falsified, making it appear as if it is coming from someone you know, such as your management or your partner company.
5- Password attack
obtaining passwords is a common and effective attack approach. Access to a person’s password can be obtained by sniffing the connection to the network to acquire unencrypted passwords, using social engineering, gaining access to a password database or outright guessing. The last approach can be done in either a random or systematic manner.
6- Drive-by Downloads
It is a common method of spreading malware. A program is downloaded to a user’s system just by visiting the site. It doesn’t require any type of action by the user to download.
Hackers look for insecure websites and plant a malicious script into HTTP or PHP code on one of the pages. This script might install malware directly onto the computer of someone who visits the site, or it might re-direct the victim to a site controlled by the hackers.
