http://www.nipc.gov/warnings/advisories/2000/00-060.htm ADVISORY 00-060 E-Commerce Vulnerabilities December 1, 2000 Based on FBI investigations and other information, the NIPC has observed that there has recently been 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: 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.
