"Increased Internet Attacks Against U.S. Web Sites and Mail Servers Possible
in Early May"
Issued 04/26/2001
Citing recent events between the United States and the People's Republic of
China (PRC), malicious hackers have escalated web page defacements over the
Internet. This communication is to advise network administrators of the
potential for increased hacker activity directed at U.S. systems during the
period of April 30, 2001 to May 7, 2001. Chinese hackers have publicly
discussed increasing their activity during this period, which coincides with
dates of historic significance in the PRC: May 1 is May Day; May 4 is Youth
Day; and, May 7 is the anniversary of the accidental bombing of the Chinese
Embassy in Belgrade.
To date, hackers already have unlawfully defaced a number of U.S. web sites,
replacing existing content with pro-Chinese or anti-U.S. rhetoric. In
addition, the NIPC previously reported on an Internet worm named "Lion" that
is infecting computers and installing distributed denial of service (DDOS)
tools on various systems. Analysis of the Lion worm's source code reveals
that, when illegally exploited, it sends password files from the victim site
to an email address located in China. For more information on the Lion DDOS
tool, refer to NIPC Advisory 01-005.
As a result of the activity already seen, together with public statements
threatening increased illegal activity, network and system administrators
are encouraged to more closely monitor their web sites and mail servers
during April 30, 2001 through May 7, 2001 for attacks that could include web
page defacements and denial-of-service attacks.
Recipients of this advisory are encouraged to report computer intrusions to
their local FBI office (http://www.fbi.gov/contact/fo/fo.htm) or the NIPC,
and to other appropriate authorities. Incidents may be reported online at
http://www.NIPC.gov/incident/cirr.htm. The NIPC Watch and Warning Unit can
be reached at (202) 323-3204/3205/3206 or NIPC.Watch@fbi.gov.
