Just as you regularly service your car, it’s important to consistently review and update your IT environment to keep it secure.

What is Cyber Hygiene? Cyber hygiene involves maintaining your devices and information to ensure they are clean and safe. Just like washing your hands prevents germs, good cyber habits protect against digital threats like viruses and hackers.

Why is Cyber Hygiene Important? Online criminals are always developing new ways to steal your information or damage your devices. Practicing good cyber hygiene safeguards your privacy and ensures your devices function properly.

How Can You Improve Your Passwords?

Use Long and Complex Passphrases: Longer passwords are harder to guess. Try using a sentence like, “I love eating pizza every Friday!”

Mix it Up: Incorporate different characters, including numbers, symbols, and both uppercase and lowercase letters. For example, “I<3EatingPizza0nFridays!” is even more secure.

Don’t Reuse Passwords: Avoid using the same password for multiple accounts. Use a password manager to remember unique passwords, so if one is compromised, your other accounts remain safe.

Update Your Operating System and Software: Keeping your software updated is akin to getting a flu shot; it protects you from new threats.

Fix Security Holes: Updates often fix security vulnerabilities that could be exploited by cybercriminals.

Get New Features: Updates may also enhance your apps with new and improved features.

Update Your Devices: Regularly update hardware devices like routers, switches, and firewalls as well.

Set Automatic Updates: Enable automatic updates to ensure you never miss an important update.

Implement Two-Factor Authentication (2FA): Two-factor authentication adds an extra layer of security, much like adding a second lock to your door.

What is 2FA?: 2FA requires two forms of identification, typically a password and a code from an authenticator app on your phone. SMS codes can also be used, but they are less secure.

Why Use 2FA?: Even if someone steals your password, they won’t be able to access your account without the second form of authentication.

Where to Use 2FA: Enable 2FA on all your online accounts, including email, banking, social media, shopping, work, and government accounts.

Avoid Using Public Wi-Fi: Public Wi-Fi is risky, as anyone can potentially eavesdrop on your activities. Instead, use your own 4G/5G modem or connect through your mobile phone.

If you must use public Wi-Fi, follow these tips to stay safe:

Use a VPN: A VPN encrypts your data, creating a secure tunnel to the internet. Avoid free VPN services.

Avoid Sensitive Tasks: Don’t perform banking or other sensitive tasks on public Wi-Fi. Wait until you’re on a secure network.

Turn Off Auto-Connect: Disable automatic connections to Wi-Fi networks to prevent your device from connecting to potentially malicious networks.

Identify Phishing Scams: Phishing scams attempt to trick you into revealing personal information. Here are some tips to avoid them:

Check the Sender: Verify the sender’s email address for any inconsistencies or errors. If in doubt, contact the sender directly.

Don’t Click Suspicious Links: Hover over links to see where they lead. If unsure, visit the website directly or call the sender for confirmation.

Be Wary of Urgent or Unexpected Messages: Scammers often create a sense of urgency to prompt quick action. If a message seems off, verify its legitimacy before acting.

Back Up Your Data: Backing up your data is essential to protect against data loss. Here’s why it’s important:

Recover from Accidents: Mistakenly deleted files can be recovered with backups.

Protect Against Ransomware: Backups allow you to restore your data without paying ransoms to cybercriminals.

Hardware Failures: Backup ensures you can quickly recover data if your hardware fails.

Use the 3-2-1 Rule: Keep 3 copies of your data, stored on 2 different types of media, with 1 copy off-site.

Review Your Privacy Settings: Your privacy settings control what others can see. Regularly review them to maintain your privacy:

Check All Your Accounts: Close and delete accounts you no longer use.

Limit What You Share: Share only necessary information to enhance your security.

Schedule Reviews: Regularly check your privacy settings and set reminders to do so.

Educate Your Staff About Cyber Safety: Cyber safety is a collective responsibility in any organization. Here’s how to spread the knowledge:

Cyber Security Awareness Training: Enroll your staff in comprehensive cyber security awareness training.

Make it Fun: Use games and stories to make learning about cyber safety engaging.

Lead by Example: Demonstrate good cyber habits for your staff to emulate.

Talk About Online Experiences: Encourage open discussions about online experiences to keep everyone informed and vigilant.

Level Up Your Cyber Hygiene: Enhance your cyber hygiene to protect against online threats. Use strong passwords, back up your data, avoid phishing scams, update your software, operating systems, and equipment, and avoid public Wi-Fi.

Password managers are fantastic tools designed to securely store and manage your passwords. Here’s why they’re so handy:

Microsoft has recently launched the Bing Wallpaper app on the Windows Store, providing an official solution for changing desktop wallpapers daily. The app features a variety of images from around the globe that have appeared on the Bing homepage, but it seems to come with several dubious hidden functions when installed on a Windows PC.

While some third-party software companies might include questionable functionalities and hidden payloads, Microsoft users expect higher standards. When similar behaviour is observed in Microsoft’s products, it tends to provoke a swift and highly negative reaction from Windows users.

There are some serious security and privacy concerns with the Bing Wallpaper app. The app not only automatically installs Bing Visual Search but also contains code to decrypt cookies stored in other browsers. Additionally, it introduces a ‘free’ geolocation web API to the system.

A developer found numerous concerning features embedded in Bing Wallpapers by Microsoft. These include attempting to alter the browser settings and set Edge as the default system browser. If Edge isn’t the default browser, the app will eventually prompt the default browser to enable the previously installed Microsoft Bing Search extension for Chrome.

Like a lot of companies recently, has quietly enabled an opt-out feature that scrapes for the content of your Word and Excel documents in order to train it’s AI system. By default, this is turned on and you need to manually turn it off so that you can opt out.

If you’re using Word or Excel to create proprietary content (ie novels, blogs, etc) or any other content that will be protected by copyright, then you’ll be wanting to turn this feature off straight away.

On a Windows PC, go into Word and then File > Options > Trust Center > Trust Center Settings > Privacy Options > Privacy Settings > Optional Connected Experiences > Uncheck box: “Turn on optional connected experiences”

Microsoft have said that the feature is not intended specifically for AI training, but their Services Agreement includes a clause granting them a worldwide and royalty-free intellectual property licence to use user content.

Intel’s 13th and 14th generation CPUs, known as Raptor Lake and Raptor Lake Refresh, have been facing some stability problems due to a flaw related to raised operating voltage.

The processors were found to request higher voltages than necessary, causing instability, crashes, and random restarts. This issue, referred to as Vmin Shift Instability, affects the clock tree circuit within the IA core, making it susceptible to reliability issues under raised voltage and temperature.

The instability may cause permanent damage to the CPU, making it unreliable. There have been reports of frequent crashes and system instability, even after installing patches.

Intel has released some microcode patches to fix the issue, with the final update (0x12B) released in September 2024. The patches change the Enhanced Thermal Velocity Boost (eTVB) algorithm and prevent the CPU from requesting raised voltages when idle or under light load1.

Intel has extended the warranty for affected processors by two years and improved its RMA process to help users with these issues.

If you’ve got problems with your 13th or 14th gen Intel processor, it’s recommended to check for the latest BIOS updates and contact Intel customer support for further help.

On the 14th of October 2025 Windows 10 will reach its end of support. After this, Microsoft will no longer provide software updates, technical assistance, or security fixes for Windows 10. Windows 10 computers will still work, but it’s recommended to upgrade to Windows 11 to make sure you have the latest features, security updates, and support.

The Extended Security Updates (ESU) program is offered by Microsoft for Windows 10, which allows users to continue receiving critical and important security updates after the end of support date. This is a temporary solution for people who need additional time to transition to Windows 11 or upgrade their current computers.

This will cost $30 (about £23) per computer per year. For businesses the cost is about twice that amount. Consumers can only purchase it for one year, whilst businesses it will be for three years.

It will only include critical and important security updates. It will not include new features, non-security updates or tech support.

It will be available closer to the end of support date.
