When you are planning your cyber security strategy, it is useful to have a good working knowledge of the types of cyber threats that are currently posing a risk. If you have never heard of the likes of ‘formjacking’, ‘cryptojacking’ and DNS poisoning attacks, then it’s time to start reading up on the latest cyber threats in 2021.
There are various different cyber threats that pose an array of risks. These threats are changing all the type, as cybercriminals develop new and more cunning ways of accessing systems and holding organisations to ransom.
Here are some of the most common cyber threats in 2021:
A backdoor allows remote access to computers or systems, without the user knowing anything about it. It is a type of malware that gets past regular authentication procedures to gain access. As a result, remote access is granted to different resources, such as file servers and databases, which means that criminals can remotely issue system commands and update malware.
This is the process of inserting malicious JavaScript code into online payment forms in order to harvest users’ payment details, including card numbers, addresses, phone numbers and more. All the while, the user is unaware that their payment details are being compromised, and that they could potentially become the victims of identity theft. The cybercriminals who steal the information go on to use it for their own financial gain, or may sell it on the dark web.
Cryptojacking involves the unauthorised use of a device to mine for cryptocurrency. The criminal installs crypto mining software on a device, and then makes use of its resources to mine for digital money or steal from digital wallets, without incurring any of the usual related costs. Hackers will usually get the software onto a user’s device by getting them to click on a link in an email, or by infecting a website or online ad with JavaScript code that auto-executes once loaded in the victim’s browser.
DoS attacks attempt to disrupt regular web traffic and bring down targeted websites by flooding systems, networks or servers with more requests than they can handle. A Distributed Denial of Service (DDoS) attack is when an attacker makes it impossible for a service to be delivered. The aim of the attack is financial, although online vandalism is another motive, with attackers targeting organisations with which they have issues.
DNS (domain name system) poisoning or spoofing attacks compromise DNS to redirect traffic to malicious websites. During the attack, hackers collect valuable information such as account numbers and passwords. Mostly, a user will not know that the website is a spoof as it will look perfectly normal.
Malware is any file or program that is intended to harm or disrupt a computer or network. Types of malware include botnets, ransomware, Trojans and remote access Trojans, rootkits, spyware and viruses and worms.
Cybercriminals use various methods to access and infect systems and devices. Some of the most common include:
These involve the installation of malware when victims visit a malicious website that they believe to be genuine.
A phishing attack involves tricking a victim into divulging sensitive information to hackers, usually via email.
Social engineering is a sophisticated method of cybercrime that involves deceiving and manipulating victims in order to gain access to their devices.
Other types of cyber-attack include SQL injections, man-in-the-middle attacks and exploits and exploit kits.
