Over 225,000 UK military personnel's data compromised in a security breach.

Shared Services Connected Ltd identified as responsible for the breach, exposing sensitive information.

UK's Defence Secretary Grant Shapps calls for a security review, citing inadequate protection by the contractor.

The incident marks the second data exposure involving an external contractor for the UK military in less than a year.

Experts urge for mandatory cybersecurity standards in defense-related industries due to insufficient investments by private contractors.

The breaches underscore the urgent need for enhanced cybersecurity and ongoing evaluation of risks posed by third-party defense suppliers.
