The MoD Afghan Data Breach: Could the Information Commissioner have done more? 

On Tuesday, the High Court lifted a superinjunction that prevented scrutiny of one of the most serious personal data breaches involving a UK Government department. In February 2022, a Ministry of Defence (MoD) official mistakenly emailed a spreadsheet containing personal details of over 18,000 Afghan nationals who had applied to move to the UK under the Afghan Relocations and Assistance Policy (ARAP).  

The breach was only discovered in August 2023, when excerpts of the data appeared on Facebook. By then, the damage was done. A new resettlement scheme for those on the leaked list was set up and has seen 4,500 Afghans arrive in the UK so far. The Afghan Relocation Route has cost £400m so far, and the Government has said it is expected to cost a further £450m. Interesting that that the High Court in May 2024 heard it could cost “several billions”. 

Shockingly, people whose details were leaked were only informed on Tuesday. A review of the incident carried out on behalf of the MoD found it was “highly unlikely” an individual would have been targeted solely because of the leaked data, which “may not have spread nearly as widely as initially feared”. On Wednesday though, the Defence Secretary said he was “unable to say for sure” whether anyone had been killed as a result of the data breach. The daughter of an Afghan translator whose details were leaked told the BBC that her whole family “panicked”.  

“No one knows where the data has been sent to – it could be sent to the Taliban, they could have their hands on it,” she said. Her grandmother, who is still in Afghanistan, is “completely vulnerable”, she added. 

This is not the first time the MoD has mishandled Afghan data. In December 2023, it was fined £350,000  for disclosing details of people seeking relocation to the UK shortly after the Taliban took control of Afghanistan in 2021. The MoD sent an email to a distribution list of Afghan nationals eligible for evacuation using the ‘To’ field, with personal information relating to 245 people being inadvertently disclosed. The email addresses could be seen by all recipients, with 55 people having thumbnail pictures on their email profiles.  
Two people ‘replied all’ to the entire list of recipients, with one of them providing their location.  

ICO’s Response 

Despite the scale and sensitivity of the latest MoD data breach, the Information Commissioner’s Office (ICO) has decided not to take any regulatory action; no, not even a reprimand! In its press release, the ICO praised the MoD’s internal investigation and mitigation efforts, stating that “no further regulatory action is required at this time”. 

Compare this case to the data breach involving the Police Service of Northern Ireland (PSNI). Last year, the ICO fined the PSNI £750,000 after staff mistakenly divulged the surnames of more than 9,483 PSNI officers and staff, their initials and other data in response to a Freedom of Information (FoI) request. The request, via the What Do They Know.Com website, had asked the PSNI for a breakdown of all staff rank and grades. But as well as publishing a table containing the number of people holding positions such as constable, a spreadsheet was included. The information was published on the WDTK website for more than two hours, leaving many fearing for their safety. 

In September las year it was announced that a mediation process involving the PSNI is to take place to attempt to agree the amount of damages to be paid to up to 7,000 staff impacted by the data breach. The final bill could be as much as £240m, according to previous reports. Compare that with the impact and cost of the latest MoD data breach. 

Other ICO enforcement actions in the past few years for security failures include: 

  • Cabinet Office (2020): Fined £500,000 for publishing New Year Honours list online. Cause? Spreadsheet error. 
  • HIV Scotland (2021): Fined £10,000 when it sent an email to 105 people living with HIV. All the email addresses were visible to all recipients, and 65 of the addresses identified people by name. From the personal data disclosed, an assumption could be made about individuals’ HIV status or risk.   
  • Mermaids (2021): Fined £25,000 for failing to implement an appropriate level of security to its internal email systems, which resulted in documents or emails containing personal data being searchable and viewable online by third parties through internet search engine results.  

In the MoD case, the ICO claims it considered the “critical need to share data urgently” and the MoD’s “steps to protect those most affected”. But urgency wasn’t the issue; it was negligence. The breach occurred during routine verification, not a crisis. Even more concerning, the ICO’s own guidance states that breaches involving unauthorised disclosure of sensitive data, especially where lives are at risk, should trigger enforcement action. 

This lack of action by the ICO raises serious questions about the ICO’s independence and willingness to challenge government departments. Even if it felt a fine was not appropriate, a report to Parliament (under Section 139(3) of Data Protection Act 2018) would have highlighted the seriousness of the issues raised and consequently allowed MP’s to scrutinise the MoD’s actions.  

This breach is a national scandal; not just for its scale, but for the lack of transparency, accountability, and regulatory action. If the UK is serious about data protection, it must demand more from its regulator. Otherwise, the next breach may be even worse and just as quietly buried. 

Yesterday, the Commons Defence Committee confirmed it would launch its own inquiry, and Dame Chi Onwurah, chair of the Commons Committee for Science Innovation and Technology, said that it is writing to the Information Commissioner pushing for an investigation. Watch this space! 

STOP PRESS: This afternoon the BBC reports that the data breach was much worse than previously thought: it contained personal details of more than 100 British officials including those whose identities are most closely guarded – special forces and spies. Is an ICO u turn incoming?

MOD Payroll Data Hacked

The government has raised concerns about a cyber attack on an armed forces payroll system, with indications pointing towards China as the suspected perpetrator. Defence Secretary Grant Shapps is set to address Members of Parliament today, although he is not expected to directly attribute blame to any specific party.
Instead, he is likely to emphasise the threat posed by cyber espionage activities conducted by hostile states.

The affected system, utilised by the Ministry of Defence (MoD), contains sensitive information such as names and bank details of armed forces personnel, with a few instances where personal addresses may also be included. Managed by an external contractor, the breach came to light in recent days, prompting government action, although there’s no evidence suggesting data was actually extracted from the system.

The investigation into the breach is still in its early stages and attributing responsibility can be a complex and time-consuming process. While official accusations may not be made immediately, suspicions are reportedly pointing towards China, given its history of targeting similar datasets.

Those impacted by the breach will receive communication from the government regarding the incident, with a focus on addressing potential fraud risks rather than immediate personal safety concerns.

At the time of writing it is not clear if the MoD has reported the data breach to the ICO as required by the UK GDPR. In December 2023, the MoD was fined £350,000 for disclosing personal information of people seeking relocation to the UK shortly after the Taliban took control of Afghanistan in 2021.

The MoD GDPR Fine: The Dangers of Email 

Inadvertent disclosure of personal data on email systems has been the subject of a number of GDPR enforcement actions by the Information Commissioner’s Office (ICO) in the past few years. In 2021, the transgender charity Mermaids was fined £25,000 for failing to keep the personal data of its users secure. The ICO found that Mermaids failed to implement an appropriate level of security to its internal email systems, which resulted in documents or emails containing personal data being searchable and viewable online by third parties through internet search engine results. 

Failure to use blind carbon copy (BCC) correctly in emails is one of the top data breaches reported to the ICO every year. Last year the Patient and Client Council (PCC) and the Executive Office were the subject of ICO reprimands for disclosing personal data in this way. In October 2021, HIV Scotland was issued with a £10,000 GDPR fine when it sent an email to 105 people which included patient advocates representing people living with HIV. All the email addresses were visible to all recipients, and 65 of the addresses identified people by name. From the personal data disclosed, an assumption could be made about individuals’ HIV status or risk.  

The latest GDPR fine was issued in December 2023, although the Monetary Penalty Notice has only just been published on the ICO website. The ICO has fined the Ministry of Defence (MoD) £350,000 for disclosing personal information of people seeking relocation to the UK shortly after the Taliban took control of Afghanistan in 2021. 

On 20th September 2021, the MoD sent an email to a distribution list of Afghan nationals eligible for evacuation using the ‘To’ field, with personal information relating to 245 people being inadvertently disclosed. The email addresses could be seen by all recipients, with 55 people having thumbnail pictures on their email profiles.
Two people ‘replied all’ to the entire list of recipients, with one of them providing their location. 

The original email was sent by the team in charge of the UK’s Afghan Relocations and Assistance Policy (ARAP), which is responsible for assisting the relocation of Afghan citizens who worked for or with the UK Government in Afghanistan.
The data disclosed, should it have fallen into the hands of the Taliban, could have resulted in a threat to life. 

Under the UK GDPR, organisations must have appropriate technical and organisational measures in place to avoid disclosing people’s information inappropriately. ICO guidance makes it clear that organisations should use bulk email services, mail merge, or secure data transfer services when sending any sensitive personal information electronically. The ARAP team did not have such measures in place at the time of the incident and was relying on ‘blind carbon copy’ (BCC), which carries a significant risk of human error. 

The ICO, taking into consideration the representations from the MoD, reduced the fine from a starting amount of £1,000,000 to £700,000 to reflect the action the MoD took following the incidents and recognising the significant challenges the ARAP team faced. Under the ICO’s public sector approach, the fine was further reduced to £350,000.  

Organisations must have appropriate policies and training in place to minimise the risks of personal data being inappropriately disclosed via email. To avoid similar incidents, the ICO recommends that organisations should: 

  1. Consider using other secure means to send communications that involve large amounts of data or sensitive information. This could include using bulk email services, mail merge, or secure data transfer services, so information is not shared with people by mistake.  
  1. Consider having appropriate policies in place and training for staff in relation to email communications.  
  1. For non-sensitive communications, organisations that choose to use BCC should do so carefully to ensure personal email addresses are not shared inappropriately with other customers, clients, or other organisations.
