Security Advisory – Adobe Breach

On Oct 3, 2013, Adobe Systems Inc. announced that its network had been breached.  The cyber attack compromised information relating to Adobe’s 2.9 million customers, including payment data such as credit card numbers, as well as the source code for popular Adobe products, such as Adobe Acrobat, ColdFusion, and ColdFusion Builder.

[UPDATE: Nov.7, 2013] The number of affected Adobe customers has expanded to 38 million.  The source code theft now also extends to the Adobe Photoshop family of products.  It has been confirmed that the stolen passwords were poorly encrypted (instead of hashed, as is standard practice).  Security researchers have been able to retrieve many passwords from the stolen data.  Therefore, we reiterate the recommendation to promptly change passwords for Adobe accounts and apply all the latest updates to Adobe products as soon as possible.”

Adobe reported that the stolen payment card information was encrypted, thus the financial risk to its customers is not believed to be critical.  Nevertheless, the company has begun the process of notifying the affected customers, offering them free credit monitoring for one year.  Other account holders have been advised to reset their passwords as a precautionary measure.

The theft of the product source code poses a more significant concern, as it increases the likelihood and volume of zero-day exploits — malicious attacks against vulnerabilities that are not yet known to either the software developer or the public.  The best way for an Adobe user to safeguard against such attacks is to:

  • Ensure that Adobe software is kept up-to-date

  • To run only vendor-supported versions of the software

  • To apply all available security updates

The same hackers thought to be responsible are linked to major breaches of giant data aggregator companies earlier this year; they are also believed to be involved in the breach of PR Newswire this week.  Investigators have determined that these hackers specialize in attacking ColdFusion vulnerabilities.  With the source code in their possession, there is enormous potential for harm.

Soon after the breach, Adobe issued security updates for Adobe Reader and Acrobat.  Although the fixes are unrelated to the breach, it is strongly recommended that all users of Adobe Reader or Adobe Acrobat apply these updates immediately.  The same recommendation shall also apply to future updates unless otherwise advised.

Network Outage: Thursday, October 10, 2013 4:41 PM – 4:43 PM

During maintenance on a firewall the device stopped passing network traffic for approximately two minutes. People using Ryerson’s wireless to access the Internet and people trying to access services outside their administrative subnets were unable to do so. Traffic is now flowing normally. This sort of maintenance process is run on the management plane of the firewall and should not have affected network traffic.

Please accept our apologies for the outage.
