  security incident notification
    - -----------------------------------------------------------------


    Our community infrastructure was recently the target of a cyber attack.
    The incident was related only to infrastructure and does not affect JBoss
    Enterprise software product offerings.


    The focus of this attack was, a machine which runs a free
    Atlassian JIRA instance used for tracking of issues with various
    related projects.  The attack was consistent with other recent high profile



    We believe the JIRA instance was compromised via a previously
    unknown cross-site scripting (XSS) attack.  This attack eventually allowed
    administrative access to the JIRA instance on April 11th, 2010, and subsequently
    user credentials from a backend database, containing passwords hashed without a
    random salt.


    Just as in the recent attacks on and's sites, the
    attack against the infrastructure  originated from Slicehost and
    shares similar traits and tactics.


    What does this mean?
    - ---------------------------------


    If you are a user of services which require a login, your account
    credentials may have been compromised as a result of this attack.


    We strongly advise users of our services to maintain different passwords for
    any other services and applications they may consume.  In the event that you
    may have used the same password on a system in addition to the
    related machines, we recommend that you change those passwords immediately.


    We also note that JBoss Enterprise software product offerings were not impacted by this


    What steps have been taken to address the issue?
    - ---------------------------------------------------------------------------


    We have taken a number of actions to help address and improve the security of
    of our offering to the community.


    * Shortly after Altassian provided a patch for the XSS attack against JIRA,
    our system  administrators applied the patches to our systems.


    * Our system administrators began an audit of these systems after the public
    disclosures of and's recent attacks. Initial
    investigation did not reveal any indications of a compromise, and we posted
    these findings on the community site on April 16, 2010. 
    Upon closer examination and application of a second round of patches  we discovered
    there had been an intrusion on the JIRA application, however, circumstances of the
    attack differed slightly from previous disclosures, and left different signatures.  This
    discovery was made on Saturday, April 17th.


    * We have quarantined the Subversion repositories in order to
    conduct an audit and help ensure their integrity before we make them
    available again.  We're also  checking other systems to make sure their
    data has not been compromised. Our investigation to date does not show any
    unintentional changes.


    * We have also forced lockout on credentials that we believe may have been at
    risk, and have notified the owners of those accounts as to the possible
    compromise of the account information.


    * We are investigating additional controls around the authentication mechanism
    of this system, and will look to improve the application's security and
    tolerance to attacks.


    * Strong system level security, including the use of SELinux in enforcing
    mode, helped ensure the integrity of the underlying OS.   Detailed logging
    helped track and recreate the attack.


    We published this announcement so that our community members may learn from
    our experiences managing through this  event and will examine their own JIRA instances
    accordingly to ensure that they are better protected and secured as well.


    Atlassian's recent update may be of value to our users, in helping to ensure
    their own JIRA instance integrity:
