Remember, staying proactive and adopting a sceptical approach towards unsolicited communications are key steps in protecting yourself from phishing attempts.

What should I do if my data is encrypted by ransomware?

If your data has been encrypted by ransomware, it is crucial to act swiftly and cautiously. Firstly, disconnect the infected device from any network or external drives to prevent the ransomware from spreading further. Do not attempt to pay the ransom as there is no guarantee that you will regain access to your data, and it may encourage further criminal activities. Contact your IT department or a reputable cyber security professional for assistance in assessing the situation and exploring potential recovery options. It is also advisable to report the incident to law enforcement authorities to help combat cyber crime and protect others from falling victim to similar attacks. Remember, prevention is key, so regularly back up your data and ensure that your security software is up-to-date to mitigate the risk of future ransomware attacks.

What are the common signs of a malware infection?

Malware infections can manifest in various ways, and being able to recognise the common signs is crucial for early detection and mitigation. Some typical indicators of a malware infection include sluggish system performance, unexpected pop-up windows, unauthorised changes to files or settings, unusual network activity, frequent crashes or freezes, and a sudden decrease in available storage space. Additionally, if your device starts behaving erratically, displays unusual error messages, or experiences unexplained data loss, these could also be signs of a malware infection. It is essential to remain vigilant and promptly investigate any suspicious behaviour to prevent further damage and protect your digital assets from potential cyber threats.

How can businesses defend against DDoS attacks?

To defend against DDoS attacks, businesses can implement several proactive measures to safeguard their networks and systems. Firstly, deploying a robust network infrastructure with sufficient bandwidth and redundancy can help absorb and mitigate the impact of DDoS traffic. Utilising DDoS mitigation services or appliances that can detect and filter out malicious traffic in real-time is also crucial. Businesses should develop incident response plans specifically tailored to DDoS attacks, outlining steps to quickly identify, isolate, and mitigate the attack. Regularly testing these response plans through simulations or drills can ensure readiness in the event of an actual attack. Additionally, monitoring network traffic for anomalies and implementing rate limiting measures can help prevent DDoS attacks from overwhelming critical systems. By combining these technical solutions with employee training on recognising potential threats, businesses can enhance their defences against DDoS attacks and minimise potential disruptions to their operations.

What measures can organisations take to prevent insider threats?

Organisations can implement several measures to prevent insider threats and safeguard their sensitive information. Firstly, conducting thorough background checks during the hiring process can help identify any potential risks posed by new employees or contractors.
