what are the Cyber Security threats in 2025

As we move into the second quarter of 2025, one of the biggest questions companies will be asking is: what are the most dangerous cybersecurity threats we need to prepare for?

Whether you're a small, medium, or large organisation, cybersecurity threats remain a top concern especially when relying on websites and cloud-based services. It’s no surprise that a recent PWC study found 39% of UK senior executives expect cloud-based threat vectors to significantly impact their organisation in 2025, more so than in 2024.

These threats are now seen as even more critical than those coming from traditional sources such as laptop and desktop endpoints, web applications, and the software supply chain.

What are the most popular cloud based threats that we could ourselves experience or come across in 2025? Are they things that we will come across in our daily working life as employees? The answer here is Yes.

In fact, employees can unknowingly become the cause of a cybersecurity incident. Something as simple as opening a malicious email attachment or downloading a file that seems legitimate can create a serious threat. That’s why it’s essential for companies to not only strengthen their defences but also educate staff on what to look out for.

TIP: Always double-check file extensions if you’re unsure about an attachment. Threat actors often use formats like .rar, .exe, .xls, and .doc to disguise malware especially in Excel or Word documents.


What are the most common cloud security vectors?

Cloud security vectors often have weaknesses, and hackers are quick to exploit them including, as mentioned earlier, the human element. Some of the most frequently used attack methods include viruses that can damage your device’s hardware or software, and malware that appears as a new homepage, unwanted plugins, or suspicious browser extensions. Email attachments remain a major threat, often disguised as legitimate files to trick users into opening them. Malicious webpages are designed to steal sensitive information such as credit card details, while pop-up windows try to lure users into clicking on harmful links. Instant messages and chatrooms can also pose serious risks, as they may contain links or embedded trojans—especially within collaboration platforms like Microsoft Teams.
