ANSIR E-MAIL:  National Infrastructure Protection Center (NIPC) "Current
E-Commerce Vulnerabilities"
(NIPC Advisory 00-60)

This advisory is intended to inform recipients that the FBI has observed an
increase in Hacker activity specifically targeting U.S. systems associated
with e-commerce and other internet-hosted sites.  The majority of the
intrusions have occurred on Microsoft Windows NT systems, although Unix
based operating systems have been victimized as well.

The hackers are exploiting at least three known system vulnerabilities to
gain unauthorized access and download propriety information.  Although these
vulnerabilities are not new, this recent activity warrants additional
attention by system administrators.

In most cases, the hacker activity had been ongoing for several months
before the victim became aware of the intrusion. The NIPC strongly
recommends that all computer network systems administrators check
relevant systems and apply updated patches as necessary.  Specific
emphasis should be placed on systems related to e-commerce or
e-banking/financial business.  The following types of exploits have been
observed:


FIRST SYSTEM VULNERABILITY

Unauthorized Access to IIS Servers through Open Database Connectivity
(ODBC) Data Access with Remote Data Service (RDS):

Systems Affected:  Windows NT running IIS with RDS enabled.

Details:  Microsoft Security Bulletin MS99-025,  NIPC CyberNotes 99-22

The NIPC is conducting further analysis of this hacker activity and
will provide additional information as it becomes available.

Additional information on the NIPC and NIPC Advisories is available at:
www.nipc.gov

Recipients are asked to report, actual or suspected, criminal activity to
their local FBI office or to NIPC, and to your military or civilian computer
response group and other law enforcement agencies as appropriate.  Incidents
may be reported online at www.nipc.gov/incident/cirr.htm.
