Such attacks often occur on insecure networks, such as public Wi-Fi, where encryption may be weak or absent.

During a man-in-the-middle attack, the attacker can eavesdrop on data transmissions, capturing login credentials, personal details, or financial information. In some cases, they can alter the data in real time, issuing false instructions or redirecting users to malicious websites. This manipulation can compromise user trust and lead to identity theft or financial losses.

These attacks are particularly insidious because they often remain undetected by the affected parties. Cybercriminals may use techniques such as ARP spoofing, DNS spoofing, or SSL stripping to execute the attack. Proper security measures, including the use of strong encryption protocols and vigilant network monitoring, are vital to prevent man-in-the-middle attacks.

Distributed Denial of Service (DDoS)

Distributed Denial of Service (DDoS) is a cyberattack method used in computer fraud to overwhelm a targeted network, website, or online service with excessive traffic. The primary goal is to disrupt normal operations, rendering the service inaccessible to legitimate users. This attack is typically executed using a multitude of compromised computers or devices, often part of a botnet.

In a DDoS attack, hackers harness the resources of numerous infected machines to generate massive volumes of data or requests simultaneously. This overwhelming influx exhausts the target’s bandwidth, server capacity, or both, causing service outages. Such attacks can persist for hours or days, significantly impacting the victim’s operations.

DDoS attacks are challenging to mitigate because they originate from many sources, making it difficult to distinguish malicious traffic from genuine user activity. Recognizing common signs of a DDoS attack, including sluggish response times and inexplicable unavailability, is crucial for timely intervention.
