Sage suffers data breach, putting details of UK and Irish businesses at risk

Online accounting software company Sage has suffered a data breach, putting the details of a “small number” of its UK and Irish business customers at risk.

As the company briefly noted on its website:

We believe there has been some unauthorised access using an internal login to the data of a small number of our UK customers so we are working closely with the authorities to investigate the situation.

Richard De Vere of the AntiSocial Engineer posted this weekend providing further information and commentary, saying that the “personal details and bank account information for employees of as many as 300 large UK companies may have been compromised.”

De Vere went on to warn of the risks of insider threats to all businesses:

“An insider threat can strike any business, Sage have an industry leading product that is secure as many cloud providers are these days. The problem isn’t with Sage, but in how companies manage these insider risks.”

Sage says it has been contacting affected customers.
