Ministry of Defence (MoD), UK

The UK Ministry of Defence (MoD) disclosed **49 data breaches** tied to its **Afghan Relocations and Assistance Policy (ARAP)** and related schemes for Afghan nationals who aided UK forces. The most severe incident—a **February 2022 spreadsheet error**—exposed **18,700 Afghans’ personal data**, including those seeking UK resettlement after the Taliban’s return. The breach, concealed under a super-injunction until July 2025, incurred **£850M+ in mitigation costs** and risked endangering lives by revealing identities to hostile actors. Other breaches included: - **Blind carbon copy (BCC) failures** (3 incidents, £350K ICO fine), exposing email recipients’ identities. - **WhatsApp messages** with insecure personal data. - **Misdirected emails** (e.g., sent to the *Civil Service Sports Club* or with incorrect classification levels). - **Physical exposure**: An **MODNET laptop screen** displaying sensitive data on public transport. - **Microsoft Forms incident** (October 2021), further compromising data. Only **5 of 49 incidents** were reported to the ICO, though the watchdog accepted the MoD’s risk assessments. The breaches stemmed from **operational negligence** during high-stakes relocation efforts, heightening risks for vulnerable Afghan allies. The **Defence Select Committee** is investigating the 2022 breach under a broader inquiry.
