AI changed the economics of an attack.
Attacks are cheaper to launch and more expensive to clean up. And Mauritius is not watching from the sidelines.
malicious breaches were AI-enabled, up 56% in a year. Mostly deepfake impersonation and AI-written malware.

Marks & Spencer, April 2025. Mature security, a large IT budget, an outsourced help desk.
Staff names and roles, gathered from public profiles
The help desk hears a convincing employee
Credentials handed over. The attackers are inside.
Online sales stopped for weeks. A profit hit of about £300M.
No firewall failed. A conversation did. AI now makes that voice perfect: a few minutes of a leader speaking in public is enough to clone it.
Six controls that make preparedness real.
No new platform. Mostly decisions. Start with the first two: MFA alone blocks over 99% of unauthorised sign-ins, and a verified help desk closes the door from the case above.
Passkeys everywhere
No phone resets
Tested backups
Approved AI only
One-page playbook
Suppliers in scope
ExCo owns it. The Board oversees it.
Cyber is an enterprise risk, not an IT line item. When either side hands its job to the IT department, nobody owns it.
| ExCo · owns and runs | Board · oversees and challenges | |
|---|---|---|
| Accountability | A named executive owns cyber risk | Holds management to account |
| Risk appetite | Proposes it, funds the controls | Approves it, monitors exposure |
| AI | Governs tools, data and access | Checks that AI use is controlled |
| Crisis | Runs the incident, makes the 2 a.m. calls | Decides on disclosure and reputation |
| Evidence | Tests, drills, metrics | Requires proof, not policies |
