cyber threats that need to be given more attention by 2021

 Now that we have a general sense of the big picture, there are some cyber threats that need to be given more attention by 2021. Let's see what they are?


1. Fake video and audio generated by Artificial Intelligence

With advances in Artificial Intelligence, it is now possible to create fake audio and video messages that are incredibly difficult to distinguish from reality. These deepfakes, as they are called, can be an advantage for hackers in some ways.


AI-generated "phishing" emails designed to trick people into handing over passwords and other sensitive data have already been shown to be more effective than those generated by humans. Now hackers will be able to throw highly realistic fake videos and audio into the mix, either to reinforce instructions in a spam email or as a stand-alone tactic.


Cybercriminals can also use technology to manipulate stock prices, say, by posting a fake video of a CEO announcing that a company is facing a financing problem or some other crisis. Meanwhile, the only real line of defense is security awareness training to raise awareness of risk.


2. Poisoning of AI defenses

Security companies rushed to adopt Artificial Intelligence models as a way to help anticipate and detect cyber attacks. However, sophisticated hackers can try to corrupt these defenses.


Opponent generating networks, or GANs, which launch two neural networks against each other, can be used to try to guess what the advocates of algorithms are using in their AI models. Another risk is that hackers will target data sets used to train models and poison them - for example, by swapping labels on samples of malicious code to indicate that they are safe, not suspect.


3. Hacking smart contracts

Smart contracts are software programs stored on a Blockchain that automatically perform some form of exchange of digital assets if the conditions encoded in them are met. Entrepreneurs launch their use for everything from money transfers to intellectual property protection.


But it is still early in their development, and researchers are finding bugs in some. The same is true of hackers, who exploited flaws to steal millions of dollars in cryptocurrencies.


The bottom line is that Blockchains were designed to be transparent. Maintaining the data associated with private smart contracts is therefore a challenge.

The goal of subnetting is to create a fast, efficient, and resilient computer network. As networks become larger and more complex, the traffic traveling through them needs more efficient routes.

4. Breaking encryption using quantum computers

Security experts predict that quantum computers, which take advantage of exotic phenomena in quantum physics to produce exponential leaps in processing power, can break the cryptography that currently helps protect everything from e-commerce transactions to health records.


Quantum machines are still in their infancy, and it may take a few years before they pose a serious threat. But products like cars whose software can be updated remotely will still be in use a decade or more from now.

What is a DDoS Attack? A Simple Definition

Since we’re all about making technical topics simple, let’s start with a basic answer to the question: What does DDoS mean (a.k.a. “What is a distributed denial of service attack”)? As mentioned above, a DDoS attack is a bit like a traffic jam on a website (but it’s intentionally caused by a hacker). Here’s a simple definition for the meaning of DDoS: A DDoS (distributed-denial-of-service) attack is when a hacker makes a website or other service inaccessible by flooding it with requests from many different devices. If you’ve also heard the term “DoS attack,” don’t let that confuse you. A DDoS attack is just a specific type of DoS (denial-of-service) attack — one that uses multiple computers/devices to attack with. How Does a DDoS Attack Work ? Just like a traffic jam floods a highway with more cars than it can handle, a DDoS attack floods a website with more requests (i.e. visitors) than the web server or other related systems can handle. Many hackers use botnets (a.k.a.

How to prevent a DDoS?

Keeping yourself protected from DDoS attacks is something that is often easier said than done because of the fact cybercriminals will often stop at nothing to gain unauthorised access to private data, and many international brands such as Netflix, AirBnB, and Spotify have all become victims in the past. In spite of this, there are certain things that can be done in an effort to prevent a DDoS attack from occurring. Denial of service attack definition Firstly, you will need to make sure that any firewalls and routers are configured in the correct manner and applied with up-to-date security patches. Similarly, it’s also worth regularly checking for security updates for your Internet of Things (IoT) devices and adding a password where possible. This is because these devices have been increasingly targeted by hackers in recent years. Doing everything in your power to keep things up to date will ensure that any bogus traffic is promptly rejected during a process whereby network traff
