                             June 18 DoS threat
                                07 June 1999

===========================================================================

We are writing to you to notify you of the possibility of denial of
service attacks on June 18.  We would like to stress that this
notification is based on information received from a third party, and
that we have not been able to independently substantiate this
information.  However, in the interests of erring on the side of
caution we felt it prudent to send out this informal warning to our
members.

The information that we have received suggests that a number of
organisations throughout the world will take part in a series of
coordinated protest events (known as J18) during 18 June 1999.  Our
understanding is that some of these groups may be planning denial of
service attacks over the Internet, most particularly against large
financial organisations within the G8 countries.  There are no further
available details about the exact source or technical details of the
activity.

While we have no information available to confirm any individual
targets we believe that all AusCERT member sites should be aware of a
potential threat on that day.
