Cyber attacks are becoming increasingly common and, no matter the size of the business, we are all at risk. An attack can come in many forms and can also have a variety of motives. From stealing confidential client data to holding businesses to ransom, a cyber security breach can be costly and damaging for any business.
We’ve compiled a list of the most common types of attack to help you understand and recognise what form a cyber attack may take, meaning that you can stay one step ahead of any potential hackers.
Malware is a term that describes malicious software. Usually this software is installed on a system by a user clicking on a dangerous link or email attachment. Once inside the system the malware can block access to key parts of a network or computer, install additional harmful software and can transmit data (spyware).
Phishing uses email to send fraudulent communications with the aim of collecting sensitive data such as logins and credit card details. Phishing emails can look extremely professional and will usually pretend to be from a reputable source.
Commonly phishing emails may have some spelling mistakes in them or may have an email or web address that doesn’t completely match with the company. It is always handy to remember that your bank and other large companies such as Amazon will put your name at the top of any emails.
Man-in-the-middle (MitM) Attacks
This happens when attackers insert themselves in the middle of a transaction. Usually on unsecured public Wi-Fi networks. By interrupting the traffic and essentially eavesdropping on a transaction any hackers are able to receive all the information that is passed, so, for example, buying something online or accessing internet banking, could mean that you are passing financial information and address details which could be intercepted.
Essentially a denial of service attack floods a network and all of its servers with so much information that it cannot cope under the strain and all the bandwidth is used up. By doing this attackers are able to stop a network from functioning and will usually demand a ransom for return of service.
