## Prediction

Over the next seven days, exploitation of fake passkey prompts targeting Microsoft cloud accounts is likely to generate a visible uptick in reported data breaches or emergency security patches among mid-to-large enterprises. Firms reliant on Office 365, SharePoint, and OneDrive will face incident response costs, potential downtime, and accelerated MFA and identity-management overhauls. Regulators and insurers may respond by signaling stricter cyber hygiene expectations and higher premiums for cloud-centric operations. Confirmation would include new major disclosures or advisories from Microsoft and national cyber agencies; disconfirmation would be effective immediate mitigation halting further high-profile compromises.

## Drivers

- CYBERCOM alert on active exploitation of fake passkey update prompts
- Attacker ability to add their own MFA methods and exfiltrate data
- High global dependence on Microsoft cloud ecosystems
