In case you missed it, last week the news headlines once again featured a serious data breach, with the revelation that the personal information of thousands of employees’ personal data had been breached in planned attack on the data of Zellis, an outsourced payroll company.

In brief, Zellis are a payroll company that provide an outsourced service to some pretty large organisations, including the BBC, British Airways and Boots. They use a piece of software called MOVEit, for transferring files between themselves and their clients.

It has been reported that Cybercriminals are exploiting a zero-day vulnerability in MOVEit, to perform a mass download of data. Data stolen includes staff ID numbers, dates of birth, home addresses, national insurance numbers and banks details.

A zero-day vulnerability is a flaw in a system or application that there is no defense against because the system or application maker is unaware it exists.

Zellis have confirmed that data was stolen from 8 of its client firms. The BBC have informed employees that their personal data was stolen, while staff of British Airways were informed their bank details may have been stolen. Many other organisations have been impacted by this attack and the numbers are expected to rise. It is not confirmed who is behind this attack, but there is speculation that notorious Cl0p ransomware group, thought to be based in Russia, may be behind it according to Microsoft.

An updated version of the MOVEit software has been released and the National Cyber Security Centre has urged organisations using this software to carry out security updates as soon as possible. However, an internet scan revealed that thousands of company databases are still vulnerable because they haven’t been updated according to reports.

Attacks like these are a reminder that all of us need to have strong security resilience in place. It is essential that you

  1. Have an understanding of your supply chain. Your company data doesn’t just reside in your own system, you likely share data via your supply chain, be that professional advisors, outsourced service providers, or even your IT suppliers. Our recent blog gives more information on how to audit your supply chain
  2. Ensure that someone in your business is receiving daily alerts about zero day threats and is ascertaining if you need to take immediate action. Our secure+ service provides this service on your behalf.
  3. Have a plan for emergency patching when new vulnerabilities are released
  4. Have a plan for ongoing patching and software updates which should happen across all platforms at least once a month
  5. It is important that organisations have Cyber Incident Response Plans (CIRP) in place that outlines procedures and guidelines for responding to any potential cyber incidents that may occur within an organization such as this MOVEit cyber breach. This plan should not only highlight steps to recover from cyber-attacks but should also detail how to communicate with internal and external stakeholders

If you believe your data may have been impacted by this breach, the National Cyber Security Centre have issued guidance, available at https://www.ncsc.gov.uk/guidance/data-breaches
