Adobe has declined to elaborate on the blog posted by the firm’s chief security officer Brad Arkin last Thursday.

The firm’s spokespeople, both in the UK and the US, have failed to provide comment about the impact on UK customers, despite repeated requests first lodged by Amateur Photographer five days ago.

A UK spokesperson today said that the company is not publicly releasing information beyond what it released on 3 October.

She added: ‘Adobe customers worldwide have been affected.

‘As customers provide us with account information, we are taking the precaution of resetting relevant customer passwords and notifying any customers who have provided us with their credit or debit card information.’
