Now, several organizations are developing another type of honeypot to trap intruders. The Science Applications International Corporation (SAIC) has established the Wireless Information Security Experiment (WISE), which runs under the 802.11b wireless communication specification. According to SAIC, the new wireless honeypot network "sits behind a device where all inbound and outbound data is controlled and captured. [The] information is then analyzed to learn the tools, tactics, and motives of wireless system exploitation in order to develop information security tools and defenses." http://www.incident-response.org/WISE.htm http://www.saic.com In the March 27, 2002, edition of Security UPDATE, I discussed "war driving" (see the URL below), a phrase that describes the act of driving around with a wireless connectivity device with an antenna attempting to connect to unprotected wireless LANs (WLANs). SAIC's wireless honeypot is a response to intruders who perform war driving. WISE will be located in a major metropolitan area in which war drivers often search for vulnerable networks. The WISE honeypot network, designed to "develop effective information security, intrusion detection, and incident response, and forensic methodologies for wireless networks," will consist of several bridged wireless nodes designed to cover a large city area. SAIC will eventually connect the wireless honeypot to a satellite broadband system that will in turn connect the initial honeypot network to a similar network in another major city. http://www.secadministrator.com/articles/index.cfm?articleid=24616 SAIC's wireless honeypot is part of the Honeynet Research Alliance, a group of organizations "actively researching, developing and deploying Honeynets and sharing the lessons learned." The alliance currently consists of 10 organizations around the world, each of which is involved in various aspects of honeypot development and research. Alliance members include the South Florida HoneyNet Project, Nodal Intrusion Forensics Technology Initiative, Incidents.org Virtual Honeynet Project, Paladion Networks Honeynet Project, Internet Systematics Lab Honeynet Project, SAIC Wireless Honeynet, AT&T Mexico Honeynet, NetForensics Honeynet, Azusa Pacific University Honeynet, and the Brazilian Honeynet Project. You'll find more information about honeypots and the alliance at the first URL below. Check out the Web site, especially if you're considering establishing a honeypot or honeynet of your own. For Windows & .NET Magazine articles about honeypots, visit our Web site at the second URL below. http://project.honeynet.org/alliance http://search.winnetmag.com/query.html?qt=honeypot Did you know that Microsoft has changed how users submit vulnerability reports? Formerly, users emailed vulnerability information to secureat_private However, the company recently removed that contact address from its Web site and now requests that users contact the company about security vulnerabilities through a Secure Sockets Layer (SSL)-enabled Web form. The new Web form will help the company collect more complete information for vulnerability reports through the many fields that users must complete before they submit a report. For example, when you visit the Web page, you'll find that the form requests information such as OS, additional hardware installed on the system, and installed security patches and service packs. The form also provides space in which to describe how someone could mount an attack by using a given flaw and what results would occur. Be sure to look at the new form at the URL below. During the transition to the new Web form, the company will still monitor the secureat_private email address. https://www.microsoft.com/technet/security/bulletin/alertus.asp ~~~~~~~~~~~~~~~~~~~~ ~~~~ SPONSOR: WORST CASE SCENARIO: Hacker Attacks Your Network ~~~~ Security exploits are often a direct result of missing patches.

Microsoft has released Security Bulletin MS02-036 (Authentication Flaw in Microsoft Metadirectory Services Could Allow Privilege Elevation) to address this vulnerability and recommends that affected users download and apply the service pack mentioned in the security bulletin. http://www.secadministrator.com/articles/index.cfm?articleid=26073 * BUFFER OVERRUN IN SQL SERVER 2000 UTILITIES Cesar Cerrudo discovered two vulnerabilities in Microsoft SQL Server 2000 and Microsoft SQL Server Desktop Engine (MSDE). The vulnerabilities are related to a buffer overrun and SQL injection. Microsoft has released Security Bulletin MS02-038 (Unchecked Buffer in SQL Server 2000 Utilities Could Allow Code Execution) to address these vulnerabilities and recommends that affected users download and apply the appropriate patch mentioned in the security bulletin. http://www.secadministrator.com/articles/index.cfm?articleid=26074 * MULTIPLE VULNERABILITIES IN SQL SERVER 2000 Cesar Cerrudo discovered three new vulnerabilities in Microsoft SQL Server 2000 and Microsoft SQL Server Desktop Engine (MSDE). The vulnerabilities are two buffer overruns and a potential for Denial of Service (DoS) attacks. Microsoft has released Security Bulletin MS02-039 (Buffer Overruns in SQL Server 2000 Resolution Service Could Enable Code Execution) to address this vulnerability and recommends that affected users download and apply the appropriate patch mentioned in the security bulletin. http://www.secadministrator.com/articles/index.cfm?articleid=26075 * BUFFER OVERRUN IN EXCHANGE SERVER 5.5 Dan Ingevaldson of Internet Security Systems (ISS) discovered a buffer-overrun vulnerability in Microsoft Exchange Server 5.5 that can let an attacker remotely compromise the server. This vulnerability is the result of an unchecked buffer in the Internet Mail Connector (IMC) code that generates the response to the Extended Hello protocol command. Microsoft has released Security Bulletin MS02-037 (Server Response To SMTP Client EHLO Command Results In Buffer Overrun) to address this vulnerability and recommends that affected users download and apply the appropriate patch mentioned in the bulletin. http://www.secadministrator.com/articles/index.cfm?articleid=26048 * CORRECTION: SYMANTEC, NOT SEMANTIC We apologize for inadvertently misspelling Symantec's name in the July 24, 2002, edition of Security UPDATE as we described a vulnerability in Symantec's Norton Personal Firewall that an attacker can exploit to execute code on the vulnerable system. We appreciate those readers who pointed out the error. 3. ==== ANNOUNCEMENTS ==== (brought to you by Windows & .NET Magazine and its partners) * GET KUDOS & A FREE TRIP TO SQL SERVER MAGAZINE LIVE!

( contributed by John Savill, http://www.windows2000faq.com ) A. Microsoft Security Bulletin MS02-032 (Cumulative Patch for Windows Media Player) identifies several version-specific patches to secure Windows Media Player (WMP) against script attacks. To manually disable WMP's HTML-processing feature, perform the following steps: 1. Start a registry editor (e.g., regedit.exe). 2. Navigate to the HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer\Preferences registry subkey. 3. From the Edit menu, select New, DWORD Value. 4. Enter a name of PlayerScriptCommandsEnabled, then press Enter. 5. Double-click the new value, set it to 0 to prevent WMP from processing HTML scripts in media files, then click OK. 6. Close the registry editor. 7. Restart WMP. 7. ==== NEW AND IMPROVED ==== (contributed by Judy Drennen, productsat_private) * NEW EMAIL SECURITY TESTS GFI's Email Security Testing Zone launched three new free email tests.

Kris wants to know whether this is true and, if so, how he can get to the LAN Manager (LM)/NT LAN Manager (NTLM) hashes for the local Administrator account to run a password cracker against it.
