Exploding pagers and walkie-talkies are a reminder of how easily your devices can be hacked – here’s how to make sure they are safe

Research shows that many people have significant concerns about security and privacy as technology advances. Statistics reveal an alarming rise in cyber threats and privacy breaches, underscoring the urgency of addressing these issues. According to IBM, the average cost of a data breach worldwide reached US$4.88 million (£3.65 million) in 2024, demonstrating the severe consequences of technological vulnerabilities.

So, are our smartphones and devices truly safe? With numerous reports of data breaches and privacy violations linked to technological development - especially concerning artificial intelligence (AI) - the recent attacks in Lebanon raise new concerns about the security of technology in an era where AI introduces complex challenges.

The pressing question for consumers is whether any of our devices can genuinely be deemed safe. If Israel can launch such an attack (and it has not confirmed it was behind the device attacks - but neither has it denied widespread reports insisting it was) other states may very well follow suit.

The Lebanon device attacks should serve as a crucial wake-up call regarding the vulnerabilities in devices we often take for granted. Part of the challenge lies in the less discussed impact of AI, which can track, analyse, and act on information in ways that pose risks to privacy and security. While AI brings substantial benefits to society, it also creates complex challenges, particularly in terms of democratic integrity and personal safety.

As technology increasingly becomes an indispensable part of our everyday lives - through smartphones, tablets, and smart home devices - it's really important to understand the risks associated with our dependency on this tech. There are some practical steps that we can all take to enhance our security and take control of our digital lives.

What you can do

1. Be careful who you buy from:One critical lesson is to be mindful of where you purchase your products. As technology advances, consumers often turn to price comparison apps to find cheaper options. But these less expensive products frequently originate from distant countries with complex supply chains. For example, in 2020, it was revealed that some Huawei and ZTE devices used in telecom infrastructure contained back doors, which led to allegations of espionage and resulted in some countries banning or limiting their use.

It's worth thoroughly researching the manufacturer before making a purchase. Before buying, check reviews and security certifications, and find out if the company has a history of security breaches or privacy concerns. Ensuring the manufacturer is reputable adds an extra layer of protection.
