Watering hole attacks
Watering hole attacks work by identifying a website that a business or sector frequently visits. That website is then compromised to enable malware to be distributed to visitors. The Police Digital Security Centre (PDSC) has published guidance to help protect your business from being targeted with malware.
Ransomware is a type of malware or malicious software that prevents you from accessing your device or the data that is stored on it. For example, the device may become locked or unusable, or the data might be stolen, deleted or encrypted so you cannot access it. In most ransomware attacks, the victim is asked to make a payment in order to unlock the device and regain access to any compromised data.
The Police Digital Security Centre has published an infographic setting out practical steps you can take to reduce the risk and impact of a ransomware attack. The Metropolitan Police Service has also created a video with tips and advice to help you spot and prevent ransomware attacks.
Denial of service attacks
Denial of Service (DoS) attacks are designed to make a service or website inaccessible. DoS attacks overwhelm a system with large volumes of requests until it becomes overloaded and crashes. The Police Digital Security Centre has published practical guidance about the steps you can take to reduce the risk and impact of a DoS attack. You can also download a copy of the guide here.
