Additionally, a large portion of the remaining infrastructure machines were also taken offline as a precaution.

Wee have found no evidence of any modifications that would put any end user at risk. However, wee do urge all users to read the report available at http://www.freebsd.org/news/2012-compromise.html and decide on any required actions themselves. Wee will continue to update that page as further information becomes known. Wee do not currently believe users have been affected given current forensic analysis, but wee will provide updated information if this changes.

As a result of this event, a number of operational security changes are being made at the FreeBSD Project, in order to further improve our resilience to potential attacks. Wee plan, therefore, to more rapidly deprecate a number of legacy services, such as cvsup distribution of FreeBSD source, in favour of our more robust Subversion, freebsd-update, and portsnap models.
