A calendar invitation can be a phishing message.

The invitation may contain a link to a fake video meeting, invoice, shared document or login page. It can also use the name of a company or person you recognise.

Check the organiser’s full email address before opening anything in an unexpected invitation. Confirm the meeting with the sender using contact details you already have.

Review whether your calendar automatically adds invitations from unknown senders. Report suspicious invitations through your email or calendar service.

Signing into Chrome or Edge with a personal account on a work computer can copy business information into that personal account.

Depending on the sync settings, this may include bookmarks, browsing history, open tabs and saved passwords.

Use a separate browser profile connected to a work account controlled by your company. Keep business passwords and browsing information out of personal accounts.

Check company computers for personal browser profiles, especially when employees use the same device for personal and business activity.

Want us to check how browser accounts are set up on your company computers? Reach out and we’ll review them with you. 01782 847208 or visit onestopcomputers.co.uk

Could your business still answer calls, take payments and access its online systems if the office internet stopped working?

A backup connection can use a second broadband provider or a 4G or 5G mobile connection. Your router can be configured to switch to the backup when the main connection fails.

The backup may only need to support essential work rather than every device in the building.

Test it at a time when a brief interruption will not affect customers. Disconnect the main service and check your phones, payment terminals, remote access and important online services.

If you don’t have backup internet, or you’re unsure whether your current setup works, contact us. We’ll help you choose an option and test the switch between connections. Find out more about what we can do for your business by visiting onestopcomputers.co.uk

Microsoft recommends at least two emergency administrator accounts for Microsoft Entra, the service that controls Microsoft 365 logins.

These accounts are used when the normal administrator accounts cannot sign in.

They should use security keys or another sign-in method that does not depend on the same phones or apps used by the normal administrators.

Store the access details securely, create an alert for every login and test the accounts at least every 90 days.

We can set up and test these emergency accounts without changing how your employees normally sign in. Need help getting on top of your IT? Give us a call on 01782 847208.

Are the days of posting AI content without anyone knowing coming to an end?

Anthropic is adding an invisible watermark to text written by new Claude models.

You won`t see the watermark. It is created through patterns in the words Claude chooses, so copying the answer into Word, an email or a website won`t remove it. Some editing may leave the mark intact too.

Anthropic plans to provide tools that can estimate whether Claude helped write a piece of text.

Those tools cannot identify the person who used Claude, show what they asked or tell how much of the finished document was written by them.

A document may carry the watermark even if Claude was only used to rewrite part of it.

Businesses can keep using Claude for drafts and editing, but staff should know that its involvement may be detectable. Anything sent to a client or published under the company name still needs to be checked for accuracy.

If your team is already using AI at work and you`re not sure what rules you need, let`s have a chat. Call us on 01782 847208.

Photos and documents can store hidden information that is not visible when you open the file.

A photo may include the GPS location where it was taken and the device used to take it.

Word, Excel and PowerPoint files may contain the author’s name, company information, comments and tracked changes. PDFs can contain details about who created them and which software was used.

Before sending a file outside your business, inspect its metadata and remove anything the recipient does not need.

Microsoft Office includes a Document Inspector for finding hidden information. For photos on Windows, open the file’s Properties and check the Details section.

Inspect the exact version you are about to send.

Drawing a black rectangle over words in a PDF may only hide the words from view. The text underneath can sometimes still be searched, copied or recovered.

Use the redaction feature in a PDF editor. Proper redaction removes the selected information from the file instead of covering it.

After saving the redacted copy, search for the removed words and try selecting and copying the covered area. Open the file in another PDF reader and check it again.

Test the document before sending contracts, financial statements, legal files or records containing personal information.

Do your employees know which company information they may share?

A simple classification system can use three labels:

1. Public information can be shared outside the business. Examples include published job adverts, press releases and information already on your website.

2. Internal information is for employees and approved contractors. Examples include internal procedures, meeting notes and business reports.

3. Confidential information needs stricter access. Examples include customer records, payroll information, bank details and legal documents.

For confidential information, explain who may access it, where it may be stored, how it may be sent and when it should be deleted.
