In March 2023, Capita, a prominent government IT outsourcer and BBC license fee collector, fell victim to a devastating cyberattack orchestrated by the Russian cybercrime gang Black Basta. The breach resulted in the theft of sensitive data, including passport scans, which were subsequently leaked on the dark web. The attack has had significant repercussions for Capita and its customers, raising concerns about data security and prompting urgent measures to mitigate the damage. 

Let’s delve into the details of this cyberattack, its impact on customers, its effects on Capita, the actions taken in response, and potential preventative measures.

Details of the Cyberattack

The cyberattack on Capita involved the deployment of ransomware by the Black Basta gang. Ransomware is a malicious software that encrypts or scrambles data on targeted computers and servers, rendering it inaccessible to the victim. In return for releasing the data, the cybercriminals demand a ransom payment.

Customers Affected in the Attack

The attack on Capita has potentially impacted a vast range of customers due to the diverse services provided by the company. Notably affected parties include:

  • Pension funds using Capita’s administrative software, as warned by the Financial Conduct Authority (FCA).
  • BBC and millions of households, as Capita holds a £456 million contract to collect television license payments.
  • Organisations involved in nuclear projects and various entities relying on Capita’s IT services, such as local councils and the NHS.

Impact on Customers

The breach has raised concerns about the security of customer data held by Capita. Specifically, compromised passport scans and other sensitive information pose significant risks for affected individuals. The leaked data, including job acceptance letters sent to teachers in Sheffield, has been made available on the dark web, exposing victims to potential identity theft, fraud, and other malicious activities.

Impact on Capita

Capita has acknowledged that the aftermath of the cyber incident will have substantial financial implications. It is estimated that the company will incur costs ranging from £15 million to £20 million to address the breach and its consequences. Additionally, the company’s reputation has been tarnished, potentially impacting client trust and future business opportunities.

Response and Mitigation Efforts

Capita has taken immediate steps to recover and secure customer, supplier, and colleague data compromised in the attack. The company has engaged in extensive forensic work, both internally and through third-party providers, to identify the extent of the breach. Efforts have been made to remediate any issues arising from the incident and reinforce Capita’s cybersecurity environment. Expected costs include specialist professional fees, recovery and remediation expenses, and investments in strengthening their security measures.

Preventative Measures

In light of the Capita cyberattack, it is essential to consider additional preventive measures to enhance data security and minimise the impact of potential future breaches. While the specifics of Capita’s security measures during the attack are undisclosed, here are some general best practices that organisations should consider:

Implement Robust Cybersecurity Protocols

Establish comprehensive cybersecurity protocols, including regular security audits, vulnerability assessments, and penetration testing, to identify and address potential weaknesses in the system.

Multi-Factor Authentication and Encryption

Employ multi-factor authentication to add an extra layer of security to user accounts and systems. Additionally, utilise strong encryption techniques to protect sensitive data, ensuring that even if hackers manage to breach the systems, the data remains securely locked and inaccessible.

Employee Training and Awareness

Conduct regular training and awareness programs for employees to educate them about potential cyber threats, including phishing attacks and social engineering techniques. By enhancing their knowledge and vigilance, employees can help mitigate the risk of falling victim to these tactics.

Regular Data Backups and Disaster Recovery Plans

Establish a robust data backup strategy, including off-site backups, to ensure critical data is regularly and securely stored. Implement effective disaster recovery plans to quickly restore operations in case of a breach or system failure.

Collaboration with Cybersecurity Experts

Engage with cybersecurity experts and consultants to assess your organisation’s security posture, obtain up-to-date threat intelligence, and implement advanced security solutions. This collaboration can provide valuable insights into emerging threats and help fortify your defences against potential cyberattacks.

Strong Encryption for Sensitive Data

Protect sensitive data, such as personally identifiable information (PII) or confidential documents, with strong encryption algorithms. Encryption converts data into unreadable ciphertext, making it useless to unauthorised individuals even if they gain access to it.

By adopting these preventive measures, organisations can significantly enhance their overall cybersecurity posture, reducing the risk of successful cyberattacks and safeguarding sensitive data from unauthorised access.


As the Capita cyberattack demonstrates, organisations must remain vigilant in protecting their data and systems from malicious actors. By implementing robust cybersecurity protocols, employing encryption for sensitive data, and collaborating with experts in the field, businesses can better defend against cyber threats and mitigate the potential fallout of successful breaches. Safeguarding data through strong encryption ensures an additional layer of protection, even if unauthorised access is obtained, ultimately bolstering data security and maintaining the trust of customers and stakeholders.
