Why it matters
We see messages about software updates on our devices all the time, particularly on our phones. Sometimes it’s because new features – like a new set of emojis – are being released. Other times it’s because there are ‘bugs’ in the code that need to be fixed.
No matter the reason, it’s important to install updates when you see they’re available. Software updates aren’t just about adding new features or fixing bugs. They’re also about fixing weaknesses, or ‘vulnerabilities’, in a system.
The risks
Vulnerabilities are flaws in an app or software that mean it could be used for purposes other than those intended. It’s these vulnerabilities that can give attackers a way to gain access to your devices and your personal information.
When vulnerabilities are identified, the developers will quickly change the code to resolve the issue and send it to your device as a software update, often through your app store. If you don't install updates as they become available, you could be leaving your device at risk of attack.
