Last week, the Apache infrastructure team disclosed a breach to their issue tracking software where an XSS exploit led to root access which led to compromised passwords. What makes it interesting is the level of detail they provided about the breach, which security policies worked, which did not work, and what they are changing to reduce the risk of another such breach. No attempt at security by obscurity here. McAfee Labs did a nice blog post on it.
Do you think the use of Apache is going to go up or down? IMHO, the breach will have no effect or might actually increase Apache usage. The reality is that all organizations have breaches regularly. Sharing detailed information like this helps us improve our security.
BTW, if your organization is not experiencing breaches, it's due to lack of visibility.
