Phishing attacks are when hackers gain unauthorised access to a device by using a fraudulent message, such as an email or text. These attacks will try to trick users into giving them login information to certain sites. They will disguise themselves to look like a real company, tricking you into trusting them and giving them your login details. Phishing attacks are extremely common as they are so simple and cheap to do and they have a high success rate.
Ransomware are when an attacker uses a piece of malware to gain access to a system and encrypt all the data. They will then ask the victim for a ransom fee or they will lose all their data. Businesses will tend to be targeted more often, in comparison to individuals, as they will have more money and reason to pay the ransom fee. For example, hackers will be able to get larger fees from a large company as they will not want to lose any data. Whereas individuals will have less money and will have less motivation to pay ridiculous fees for their data.
Internal attacks are another common cyber security threat in which employees of an organisation will abuse their privileges to inflict damage to the company’s system, for their own personal gain. This is a difficult issue to overcome as there is no definitive way of preventing it from happening, you must simply trust your staff. They could also accidentally allow their accounts to be accessed by downloading disguised malware. This is why it is important to sufficiently train staff to be able to identify threats and prevent this from happening.
The Internet of Things allows users to connect many smart devices in one place. However, not all smart devices are as secure as others, with some having much stronger security systems installed. Hackers can use this to their advantage by targeting the weaker systems to sneak malware onto the network, allowing it to target and access other systems. IoT devices are a much easier target as people will tend to overlook them and not apply the suitable security updates, making them easier to infiltrate.
