Exhibit 2

From: Jennifer Granick [mailto:[e-mail]] Sent: Saturday, August 09, 2008 5:14 PM To: Mahony, leuan (BOS - X75835) Cc: Cindy Cohn; Kurt Opsahl; Marcia Hofmann Subject: CRITICAL INFORMATION: MBTA v Anderson et al

Dear Mr. Mahony: This email is to follow up on my phone call to you of just a few minutes ago. As you know, Mr. Anderson, Mr. Ryan and Mr. Chiesa provided your client MBTA with a confidential three page summary of their research and recommendations for securing the fare collection system. It has just come to our attention through third parties at the Defcon conference that plaintiffs have made this report publicly available on the court's pacer website by filing the document as an exhibit. This confidential document contains the checksum information without which an attacker can not create a forged card. This information is highly sensitive, which is why my clients planned to withhold it from their presentation. We strongly urge you to take emergency measures to have it removed expeditiously. Best wishes, Jennifer Granick
