If something doesn’t look right — act immediately. Quick action can stop fraud before it spreads. This guide covers what you should do, what Moss will do, and how to help your team stay alert.


1. Steps to take immediately

If you suspect unauthorized activity in your Moss account, take these five actions without delay:

  1. Block the affected card(s)
    Go to the Moss Web or Mobile App > select the card > block or freeze it instantly.

  2. Change your Moss password
    Update your credentials under Profile > Settings > Security.

  3. Contact Moss Support immediately
    Use the in-app chat or email support@getmoss.com to report the issue. The sooner we know, the faster we can intervene.

  4. Remove any suspicious devices
    Review recent login sessions and revoke access to unknown or untrusted devices.

  5. Notify your admin or finance lead
    If you’re not an account admin, alert someone who can review settings, controls, and team access.

  6. Review your transactions

    Review and check your transaction history for any transactions you didn’t authorise.

Don’t assume it’s nothing. If in doubt, report it.


2. How Moss will support you

When you report suspicious activity, our team acts fast. Here’s what happens next:

  • We flag and monitor your account for further anomalies

  • If needed, we block all cards, we restrict the user, lock high-risk sessions, and reset credentials

  • We will block any malicious agents / actors

  • Our security team conducts an internal review and shares key findings

  • You’ll receive clear instructions on next steps and account recovery

  • We will support to recover any suffered losses and we will update you in every step

  • We will support with security / fraud materials to raise employee awareness

We document every action for audit purposes and compliance reporting — and we’ll keep your team informed throughout the process.


3. Share security awareness with your team

Fraud prevention works best when the whole company is informed. Moss offers a simple, shareable fraud awareness pack for admins to distribute internally.

It includes:

  • Moss security promises (“We will never…”)

  • Phishing and scam red flags

  • Safe usage tips for cards, invoices, approvals

  • Guidelines on what to do if something goes wrong

Request the pack: Contact your Customer Success Manager or Moss Support — we’ll send it directly to you.

Pro tip: Build security into your onboarding and finance policy docs. Repetition builds habits.
