-----Original Message----- From: NIPC Watch [mailto:nipc.watch@private] Sent: Friday, October 05, 2001 7:49 AM To: daily Subject: NIPC Advisory 01-023, 5 October 2001 ADVISORY 01-023 Update to NIPC Advisory 01-003 "E-Commerce Vulnerabilities" October 05, 2001 The National Infrastructure Protection Center (NIPC) continues to observe hacking activity targeting the e-commerce or e-finance/banking industry. Over the past several months, hackers have increased their targeting of several third-party service providers that employ weak security practices. This advisory re-emphasizes NIPC Advisory 01-003, "E-Commerce Vulnerabilities," dated March 08, 2001, in view of the continuing threat to e-commerce networks. Hackers are targeting third party service providers because of the access they have into a partner company and the proprietary information contained therein. Because the level of security can differ between a third-party service provider and a partner company, hackers attempt to exploit these security inconsistencies. The most prevalent exploit being used to gain access to targeted systems is the Unicode vulnerability found in the Microsoft Internet Information Services (IIS) web server software. For additional information on this topic please refer to: http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security/ bulletin/MS00-086.asp Patches for the Unicode exploit have been available for some time. The appropriate patches for Windows based systems are found in a Microsoft scanner released at the following site: http://support.microsoft.com/support/kb/articles/q303/2/15.asp?id=303215&sd= tech The NIPC strongly recommends that all systems administrators check relevant systems and apply the updated patches, especially for systems related to e-commerce or e-banking/financial businesses. Computer users are advised to keep their anti-virus and systems software current by checking their vendor's Web sites frequently for new updates, and to check for alerts put out by the NIPC, CERT/CC, and other cognizant organizations. 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 the 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, toll free 1 (888) 585-9078, or nipc.watch@private
