It is often a small height wave characterized by a strong swash and a weak backwash. With a low frequency - around 6-8 per minute - the constructive wave will carry sediments and sand up the beach. On the opposite side of the spectrum, the destructive wave is a high-energy wave that ...
A worm is a form of malware (malicious software) that operates as a self-contained application and can transfer and copy itself from computer to computer. It’s this ability to operate autonomously, without the need for a host file or to hijack code on the host computer, that dist...
In recent years, there have been worldwide reports of massive tsunamis, drawing attention to how tsunamis are intensified by submarine landslides triggered by earthquakes. However, precise data on tsunamis caused by submarine landslides are scarce, leadi
A rogue wave is a wave which is twice the significant wave height of the region. They are bigger than the other water waves in the surrounding sea at that particular time.Rogue waves can be deadly since they are unpredictable and may strike a ship anytime. They can disable and sink the ...
Wipers, or destructive ransomware, threaten to destroy data if the victim does not pay the ransom. In some cases, the ransomware destroys the data even if the victim pays. This latter type of wiper is often deployed by nation-state actors or hacktivists rather than common cybercriminals. ...
water along the coast is drawn seaward and the sea floor near shore is exposed momentarily, typically for about five minutes before the first crest hits. A tsunami is usually experienced as a series of waves, called a wave train, that amplifies the destructive nature of these natural disasters...
Botnets have been behind several of the most destructive cyberattacks in recent years. Here’s a closer look at a few of the most notorious botnets. Conficker With over 10.5 million devices under its control at its height in 2008, the Conficker botnet is still one of the largest botnets eve...
The larger the mass or the faster the acceleration, the stronger the gravitational wave. What types of events create these waves? All gravitational systems can create gravitational waves. However, gravitational waves are very weak. Even Einstein believed it would be nearly impossible to detect ...
Although old fault lines can occasionally produce small earthquakes, the most destructive ones occur in geologically active areas, near the boundaries of continental plates. When an earthquake happens under the ocean, it may produce a tsunami, or huge wave, that travels rapidly outwards from its ...
