       WASHINGTON, Feb 13 (Reuters) - A U.S. government data
breach disclosed earlier this year was tied to a bug in
enterprise software maker Atlassian's  TEAM.O  Confluence suite
of collaboration tools, an IT contractor said on Tuesday.
    CGI Federal, an IT contractor and unit of CGI Inc  GIBa.TO ,
said in a statement that it was working "with authorities and
clients to identify and disclose any data affected by the
Confluence exploitation," which was made public back in October.
    Reuters has been unable to determine the size and scope of
the breach. On Monday, the Government Accountability Office told
Reuters that 6,000 current and former GAO employees had been
victims of a data breach by an unnamed "threat actor" in
connection with the hack. Whether any other government agencies
have been affected has not been publicly disclosed.
    Atlassian said in a statement that it had warned customers
that hackers were exploiting the bug on Oct. 3 and that it had
been assisting them with their response. The U.S. cyber watchdog
agency, the Cybersecurity and Infrastructure Security Agency,
did not immediately return an email.
