On 28 May 2025, Apple released an important update – iOS 18.5 – addressing a critical security vulnerability that could allow attackers to access sensitive data via malicious image files. The issue reportedly affected iPhones running iOS 18, including devices from the iPhone XS onwards. While this sounds serious, it’s not uncommon. Apple, like most major tech firms, regularly releases patches to protect users from newly discovered threats.
Some clients have asked whether this update requires urgent action. The vulnerability is real – but if your devices are managed by Dr Logic’s Apple Device Management Service, there’s no need to worry. iOS 18.5 has already been addressed as part of our regular patching routine.
It’s important to note that even under full device management, some updates – including those for iOS – may still require user interaction, such as accepting the update or restarting the device. Apple does not currently allow forced updates to install silently without any user involvement. However, we monitor update status and ensure no device is left unpatched for long.
This update is a good reminder that keeping business devices up to date is one of the simplest and most effective ways to protect your company’s digital environment.
Why updates matter – and why automation is essential
1. Cyber Threats Don’t Wait. Neither Should You.
The techniques hackers use to exploit systems evolve constantly. A vulnerability that didn’t exist last week may suddenly be discovered and weaponised. In this case, the flaw involved how iOS processed image files – a relatively common attack vector because image files are easily shared and trusted by users.
In business environments where devices access everything from emails and files to passwords and cloud applications, even a brief window of exposure can have major consequences.
2. Out-of-Date = Wide Open to Attack
Every day that a device runs on out-of-date software is a day it may be vulnerable to known threats. Cybercriminals often target these gaps because they know many organisations delay updates or leave them to individual users.
When you scale up – managing 50, 100 or 500 devices across locations – this quickly becomes difficult to track. And in regulated industries, unpatched systems can compromise compliance with standards like Cyber Essentials, ISO 27001, and others.
3. Why Relying on Users Doesn’t Work
While operating systems do prompt users to install updates, many people delay them, postpone reboots, or ignore notifications entirely. That’s understandable – people are busy, and they don’t want their work disrupted.
That’s why centralised update management is essential. With our Apple and hybrid device management solutions, updates are scheduled, monitored, and enforced where possible – keeping exposure windows tight and security posture strong.
4. It’s Not Just About Security: Performance Matters Too
While security is the most urgent reason to stay updated, there are other benefits too. Updates often improve performance, fix bugs, and introduce features that make work smoother. A slow device or buggy behaviour might simply be down to an outdated OS.
Keeping systems current also helps avoid unnecessary support requests and frustration for your teams.
What should businesses do next?
If Dr Logic already manages your devices, the iOS 18.5 update has been accounted for in your scheduled maintenance programme. In most cases, your team’s iPhones will have received the update prompt automatically, with completion tracked and followed up where necessary.
If you’re unsure about how updates are handled in your business – or whether patching is being consistently applied – now is a good time to take stock. Ask yourself:
- Do you know which devices are currently unpatched?
- Are end users responsible for applying updates themselves?
- Could you demonstrate patch compliance during an audit?
- Are Apple and non-Apple devices treated with the same level of care?
If the answer to any of these is unclear, we can help.
“iOS 18.5 is already covered under our Apple Device Management Service – no disruption, no loose ends.”
