On or about 20 January 2013, AMSAT-NA's main web site www.amsat.org was compromised by an attacker, with the contents of the supporting database, including non-public information, posted on other publicly available web sites.
It is likely that the attacker gained enough access to the site to post arbitrary and possibly illegal content, so out of an abundance of caution the main site was shut down.
Neither the AMSAT store nor the Fox project web site were affected by this breach. Mail services remain operational.
The main site was developed roughly 10 years ago by AMSAT volunteers under a more benign Internet threat environment. The team that built that site is no longer associated with AMSAT, so work has been underway over the last several months to move to a modern, maintainable, secure infrastructure. This recent breach will accelerate that activity. In the interim, www.amsat.org will have limited content.
