If you’re running a small or medium-sized business, then you may not have a dedicated IT department. But, you’re still at high risk of a cyberattack and you should be aware of all the different types of cybersecurity attacks that can happen.
Knowing what they are will help you to defend against them and prepare a good response if you do become a victim of a cyberattack.
Let’s take a look at the variety of cyberattacks that are possible:
You’ve probably heard of the term phishing. It refers to when emails are sent to your business, seemingly from reputable sources. The aim of the email is for you to open it and provide the information they require, usually login details and passwords.
This is achieved by directing you to a website that looks like the one you usually use but isn’t. While you think you’re entering your details onto the official site, the hackers are stealing the information and will quickly use it themselves.
You need to train your staff to be cautious, especially when using links in emails.
SQLs are databases that can hold a vast amount of data for you, and these are very popular. An SQL injection is when a code is put into your SQL database.
The purpose of the code varies; it can collect information, destroy the existing data, or allow the hacker to hold your business to ransom by actually taking the information in one dump. It’s one of the most common hacking techniques.
To protect yourself from this type of threat, you need to use parameters in your SQL database. These ensure that every parameter is checked and not just the premise as a whole. It makes it much harder for someone to inject or change your SQL programming and access information.
DDOS or Distributed Denial Of Service is when a specific server is targeted with traffic. The result is that your website becomes inaccessible because there is too much traffic on the web. It’s a brilliant and effective technique that has created issues for some of the largest companies in the world.
Traffic means an incoming message, connection requests, and fake packets, all of which occupies the bandwidth and prevent genuine customers connecting with your site.
It’s common for these types of attacks to be accompanied with a ransom demand, blocking your ability to trade until the ransom is paid, usually in cryptocurrency.
You’ve almost certainly heard of malware, it’s malicious software and comes in a variety of guises, including spyware, ransomware, worms, and viruses. It’s often introduced to a system when a user clicks on a bad link or email attachment. The malware can appear without you knowing.
The malware can then secretly collect your data and transmit it to the hacker, or it can block your access to specific software components. It can also add more malware and even make your system unusable.
Hackers may issue a ransom demand but they may also benefit from your systems being damaged.
This is often referred to as an eavesdropping attack as an attacker will slot into your system between two parties. This gives the hacker access to all the data going between the two parties, allowing them to filter it and steal anything useful. In many ways, it’s like listening to a conversation between two people.
The most common man-in-the-middle attacks start on unsecured public Wi-Fi networks. Once the attacker is on your system, they can choose the second party that they wish to connect with and begin stealing secrets.
This type of hack involves non-DNS traffic being sent with port 53, the DNS port. In effect, the data is changed to look like DNS traffic, but its true nature is hidden. There are times when this can be done for good reason, but hackers do it in order to steal information which can be sent out the back door of your system without any noticing or realizing.
Networks often discover vulnerabilities and will advertise this fact to users. The aim is to help them protect themselves from the potential threat while a patch is created to stop the issue permanently.
However, hackers will read about the vulnerability and exploit it, attempting to gain access to the network and steal information.
The name comes from the fact that you have to be constantly aware once a vulnerability is discovered because an attack is likely to happen.
