OCIPEP DAILY BRIEF Number: DOB02-146 Date: 17 September 2002



Slapper worm continues to spread
The Linux Slapper worm continued to spread quickly over the weekend and into
Monday, with more than 6,700 compromised servers as of early Monday morning. The
worm is creating a peer-to-peer attack network that could eventually be used to
hit other servers, according to Al Huger, an official at security company
Symantec. Huger warns that "with the pipes these (infected servers) are
connected to, this network could easily take a large enterprise off the
Internet." (Source: CNet News.com, 16 September 2002)

Pipeline construction plan criticized by NWT government
Imperial Oil's plan to speed up development of a Mackenzie Valley pipeline may
not be realistic, according to the Northwest Territory's minister of economic
development. The plan to have gas flowing by 2007 is a year sooner than previous
estimates and may not provide enough time for the environmental review process,
which is expected to take two to three years to complete. Construction would
take another three years. The company will also need to negotiate revenue
sharing with the Deh Cho First Nations. (Source: CBC News, 16 September 2002)

Comment: Two northern pipeline projects are currently at the planning stage: one
from the Alaska gas fields through Yukon down to the U.S. markets and another
running from the Mackenzie Delta to northern Alberta. Media reports have
suggested that U.S. subsidies may speed up the Alaskan project. Background
information on the Mackenzie pipeline project can be viewed at

Research to protect Canadians in case of CBRN attack
Two 5-year research projects aimed at protecting Canadians in the event of a
chemical, biological or nuclear attack will soon be undertaken by Cangene, a
Winnipeg-based biotechnology company. Research, which is estimated to cost $170
million, will be funded by the federally launched Chemical, Biological,
Radiological or Nuclear Research and Technology Initiative and will be
administered by Defence Research and Development, a National Defence agency.
"These projects are in direct response to the heightened interest in biological
warfare," said Dr. John Langstaff, Cangene president and CEO. The first project
will target creating and manufacturing antibodies which would be needed to treat
the Ebola and Marburg viruses. The second project will study how Leucotropin, a
protein which was developed by the company and used to fight cancer, may also be
effective to treat white-blood cell damage emanating from exposure to radiation.

Securing the power grid
An attack on North America's power grid could have serious consequences for the
entire global economy. One proposed solution is locally generated energy and
decentralized power grids, using renewable sources of energy. This would then be
used to electrolyze water and separate out hydrogen that can be used to power
fuel cells. (Source: globeandmail.com, 16 September 2002)

Comment: An economical industrial process for producing hydrogen has not yet
been developed, largely because a suitably low-cost catalyst for the process has
not been discovered.

White House Official Release of the National Strategy to Secure Cyberspace
Richard Clarke, Special Advisor to the President on Cyber Security, will
publicly unveil a draft U.S. National Strategy for Securing Cyberspace on
September 18 at Stanford University in California. The over 2,000-page strategy

in July by Tom Ridge, Director of the Office of Homeland Security. Among the
speakers participating in the event will be Margaret Purdy, Associate Deputy
Minister for National Defence with responsibility for OCIPEP, who will highlight
the importance of Canada-U.S. critical infrastructure protection cooperation and
the need to address the global dimensions of cyber security.

Comment: The Strategy will be made publicly available on the White House web
site immediately following the public announcement on a feedback link at:
www.securecyberspace.gov. It is portrayed by U.S. officials as a "living
document" to be refined through consultations with the public and the private
