Recently we’re seeing a noticeable increase in phishing attacks that don’t start with an email.
Instead, scammers are contacting colleagues through phone calls, text messages, Slack or Teams, posing as our IT Support or Service Desk teams. These messages can be very convincing and often create a false sense of urgency – for example, claiming your account is about to be locked or your device needs a ‘critical update’ – to pressure you into acting quickly.
Please take a moment to read the guidance below and help keep yourself and our business secure.
How to protect yourself
How to protect yourself
-
Never share your password or Multi‑Factor Authentication (MFA) codes.
Our Service Desk and IT teams will never ask for this information — under any circumstances. -
Only approve MFA prompts you’ve personally initiated.
If you receive an MFA request you weren’t expecting, deny it immediately and report it. -
Be cautious of unexpected calls or messages claiming to be from IT.
Scammers can spoof phone numbers and use publicly available information to appear legitimate. -
Always verify the caller.
If someone contacts you claiming to be from IT or the Service Desk, politely end the call. Then use the official phone number listed on our internal portal or directory to call the Service Desk directly. -
Never install software or follow instructions from an unverified source.
Only take action when you are confident the request is genuine and from Carnival UK. -
Don’t feel pressured.
Scammers rely on urgency, authority and intimidation. Our IT and Service Desk teams will never rush, pressure or bully you into taking action.
If something doesn’t feel right…
If you think you’ve been targeted — or if you’ve already interacted with a suspicious call or message, even accidentally — report it straight away.
- Contact your local Service Desk
- Submit a ticket via the normal support channels
- Or email the GCS team at cyber@carnival.com.
When it comes to potential scams, it’s always better to report and be safe.
