4. DDoS Attacks
Definition and Description
The term “Distributed Denial of Service” refers to a particular kind of cyberattack that occurs when a cyber intruder utilizes numerous hijacked devices or systems to saturate a targeted website, server, or network with a great deal of traffic or requests. A DDoS attack seeks to take over the target system, rendering it inaccessible to authorized users and disrupting the service.
A botnet is a network of computers that have been infested with malware and are currently under an intruder’s control. It can be utilized to launch a DDoS assault. The target system can be efficiently overloaded and rendered inoperable by the intruder using the botnet by transmitting a lot of traffic or queries to it.
Distributed Denial-of-Service (DDoS) attacks in 2023
Some of the latest trends in DDoS attacks are mentioned below:
|A vulnerable server receives a modest quantity of traffic and replies by sending a large volume of traffic to the intended recipient in an amplification attack. It enables attackers to increase the volume of traffic they may deliver to the target, strengthening the attack.
|Networks of hacked Internet of Things (IoT) devices that may be employed to conduct DDoS assaults are known as IoT botnets. Attackers will become increasingly dependent on IoT botnets in 2023 because there are so many susceptible IoT devices and so few security safeguards in place to defend them.
|Application-layer attacks are designed to deplete the resources of specific apps or services, like web servers or databases, by delivering a huge number of requests. These attacks may be more challenging to identify and stop than other DDoS attacks.
|Ransom DDoS attacks
|Attackers who use ransom DDoS tactics promise to conduct a DDoS attack against a target if a monetary ransom is not paid. Attackers are utilizing this technique to extort funds from companies and organizations more frequently in 2023.
|5G-based DDoS attacks

5. Man-in-the-Middle (MitM) Attacks
Definition and Description
A cyberattack known as a “man-in-the-middle” (MitM) attack occurs when an attacker listens in on a conversation between two people and steals or modifies sensitive data without the other party’s knowledge. In a MitM attack, the attacker can read, change, and read between the two parties’ communications without either party’s knowledge or agreement.
By standing in the way of the two parties and intercepting their communication, the attacker efficiently functions as the channel’s middleman. ARP spoofing, DNS spoofing, SSL stripping, or phishing attacks are just a few of the techniques the attacker can employ to conduct a MitM attack.
Popular MitM attack techniques in 2023
These are some common MitM attack strategies that will be used in 2023:
|Intruders can employ ARP (Address Resolution Protocol) counterfeiting in order to intercept network traffic by tricking the device used by the victim into rerouting traffic to the intruder’s device by delivering false ARP messages to the victim’s device.
|The goal of a DNS (Domain Name System) spoofing attack is to route traffic from the device of the victim to a fraudulent website by intercepting the victim’s device’s DNS request and sending a phony DNS response.
|HTTPS traffic is intercepted via SSL (Secure Socket Layer) stripping attacks, which downgrade the encrypted channel to an unsecured HTTP connection. As a result, the intruder is able to see and change the two parties’ dialogue.
|To trick users into connecting to the phony network, attackers can create a bogus Wi-Fi network with a name that sounds similar to a real network. As soon as they are in contact, the attacker can listen in on and change the victim’s dialogue.
|Attackers can deceive users into supplying confidential data by sending fraudulent emails that look to be from a reputable source, like a bank or other financial institution, using email spoofing techniques.
|Attackers can obtain confidential information or take control of Bluetooth-enabled devices by intercepting and manipulating Bluetooth signals using Bluetooth spoofing tactics.
How to prevent and mitigate MitM attacks?
Some of the premier ways to prevent and mitigate MitM attacks:
- Use Encryption,
- Keep Software and Systems Up-to-Date,
