Update - 30 October 2013: the estimated number of customers affected has been revised to 38 million

Last week, Adobe confirmed that customer information affecting 2.9 million users was stolen in ‘sophisticated attacks’ on its network.

Adobe’s most current advice indicates that data stolen included customer passwords, ‘encrypted’ credit card numbers, and the source code for some of its products.

Adobe says it will endeavour to directly contact customers whose credit card information was affected.

It has also reset customer passwords as a precaution.

If you have an Adobe ID or have purchased a product from Adobe online, or registered your details on Adobe’s site, we advise you to change your password as soon as possible.

If you use similar logon information for other online services, you should also change these, ensuring you choose a unique password each time.

Adobe’s advice states that the stolen credit card numbers were ‘encrypted’, however, if you have credit card or financial details registered with Adobe, you should carefully monitor your accounts for any unusual activity, reporting it immediately to your financial institution.

Source code was stolen for Adobe Acrobat, ColdFusion and other products. Adobe has stated it is “not aware of any specific increased risk to customers” as a result of the stolen source code.

Discovery of an application’s source code can, however, provide a useful basis for the future development of exploits for the software.

If you use Adobe products you should ensure you are using the latest versions, and that all your software is up to date.
