In Focus: Cybercrime; Microsoft Hotfix; Eliminating Spam ==== by Mark Joseph Edwards, News Editor, markat_private The Computer Security Institute (CSI) released the "2003 Computer Crime and Security Survey," its eighth annual report conducted in association with the FBI. The report shows that despite shifts in trends, cybercrime remains a serious problem, as you well know. Highlights from the report show that financial losses from security breaches have dropped by about 56 percent. Last year, respondents reported losses of about $455,848,000; this year, respondents reported losses of about $201,797,340. However, though financial losses dropped, roughly the same number of incidents occurred. The report indicates a huge drop in losses from financial fraud, the most costly security problem. Last year, losses totaled $116 million; this year, losses totaled about $9.1 million. The largest losses came through the theft of proprietary information, with respondents reporting an average loss of about $2.7 million. For the second most costly security problem, however, Denial of Service (DoS) attacks, losses increased about 250 percent--to more than $65.6 million. According to CSI Director Chris Keating, "The trends the CSI/FBI survey has highlighted over the years are disturbing. [Cybercrimes] and other information security breaches are widespread and diverse. Fully 92 percent of respondents reported attacks; furthermore, such incidents can result in serious damages ... Clearly, more must be done in terms of adherence to sound practices, deployment of sophisticated technologies, and most importantly adequate staffing and training of information security practitioners in both the private sector and government." If you want to see the complete survey results, you can obtain a copy by submitting a request form at the CSI Web site. http://www.gocsi.com/forms/fbi/pdf.html Microsoft Hotfix Speaking of cyber attacks, you're probably aware that Microsoft has released a new security bulletin, MS03-019 (Flaw in ISAPI Extension for Windows Media Services Could Cause Code Execution). According to Microsoft, the problem affects Windows 2000 and Windows NT systems. The company initially rated the problem's severity as "moderate," noting that the DoS would lead to the server rebooting itself. However, Mark Maiffret of eEye Digital Security pointed out that according to his company's tests as well as the tests that vulnerability discoverer Brett Moore conducted, the problem is far more serious than Microsoft first indicated. The tests show that the problem isn't simply a Denial of Service (DoS) issue. According to Maiffret, "If you're running Windows Media Services on IIS, attackers can spawn a remote shell command prompt on your vulnerable system." Microsoft has modified the vulnerability rating to "important" and re-released its related security bulletin. Administrators should patch their systems soon as possible to avoid having an intruder running rampant through a remote command shell. Eliminating Spam Because I've mentioned junk mail recently, I want to share a couple of my experiences in "taking out the trash." I run a mail server with a good built-in filtering subsystem. Typically, I receive anywhere from several hundred messages per day (weekdays) to 50 messages per day (weekend days). On average, my basic filters can eliminate at the gateway about 30 percent of the junk mail that I receive. But that's simply not effective enough. I've found that if I relay my email messages through a server running a Bayesian filtering system, I can eliminate more than 95 percent of the junk mail once destined for my Inbox. For details about Bayesian filtering, visit Paul Graham's Web site, on which you'll find several excellent articles. http://www.paulgraham.com/articles. Several Bayesian filtering systems are commercially available today. However, because many of you are under serious budget constraints, you might need a shareware solution. The shareware filtering solution I use now is SpamAssassin, which many of you already know and use. Although SpamAssassin was developed for Linux platforms (see the first URL below), you can install it on Win32-based systems. (You can also integrate it into Microsoft Outlook, Lotus Notes, and Novell GroupWise.) For details about how to use SpamAssassin on Win32 platforms, see the second URL below. Because Windows users typically prefer a GUI interface to handle configuration, check into the Windows-based GUI configuration interface for SpamAssassin (see the third URL below). SpamAssassin can probably also be integrated to work with Microsoft Exchange Server, but I haven't come across exact details. If you can direct me to such information, please send me an email message. http://www.spamassassin.org http://www.openhandhome.com/howtosa.html http://www.openhandhome.com/saconf.html SpamAssassin has many slick features, such as automatic learning for whitelist creation. As with all junk-mail filtering software, you'll have to tweak the parameters to suit your mail influx. After a few days of use, you should be able to filter out 95 percent or more of the junk mail you receive. So if you need a cheap way to deal with junk mail and you have time to spend on such a project, be sure to check out SpamAssassin. ==================== ==== Sponsor: Panda Software ==== YOU DESERVE FREE PROTECTION AT HOME!

Security Risks ==== contributed by Ken Pfeil, kenat_private Multiple Vulnerabilities in Microsoft IIS SPI Dynamics and NSFOCUS discovered four new vulnerabilities in Microsoft IIS 5.1, IIS 5.0, and IIS 4.0, the most serious of which can result in the execution of arbitrary code on the vulnerable system. A cross-site scripting vulnerability affecting IIS 5.1, IIS 5.0, and IIS 4.0 involves an error message about the redirection of a requested URL. IIS 5.0's incorrect validation of requests for certain types of Web pages, known as server-side includes, results in a buffer overrun. A flaw in the way IIS 5.0 and IIS 4.0 allocate memory requests when constructing headers to be returned to a Web client results in a Denial of Service (DoS) vulnerability. IIS 5.1 and IIS 5.0's incorrect handling of an error condition when they receive an overly long Web Distributed Authoring and Versioning (WebDAV) request also results in a DoS vulnerability. Microsoft has released Security Bulletin MS03-018 (Cumulative Patch for Internet Information Service) to address these vulnerabilities and recommends that affected users immediately apply the appropriate patch mentioned in the bulletin. http://www.secadministrator.com/articles/index.cfm?articleid=39122 DoS in Microsoft WMS for Win2K and NT Brett Moore discovered a new vulnerability in Microsoft Windows Media Services (WMS) for Windows 2000 and Windows NT that can result in a Denial of Service (DoS) condition. This vulnerability stems from a flaw in the way nsiislog.dll processes incoming requests. An attacker can exploit this vulnerability by sending specially formed communications to the server that cause Microsoft IIS to stop responding to Internet requests. Microsoft has released Security Bulletin MS03-019 (Flaw in ISAPI Extension for Windows Media Services Could Cause Code Execution) to address this vulnerability and recommends that affected users apply the appropriate patch mentioned in the bulletin. http://www.secadministrator.com/articles/index.cfm?articleid=39123 Buffer Overrun in AnalogX Proxy Server for Windows K. K. Mookhey discovered a vulnerability in AnalogX Proxy 4.13 and earlier that can result in the execution of arbitrary code on the vulnerable system. This vulnerability stems from a buffer-overflow condition. AnalogX has released version 4.14, which isn't vulnerable to this condition. http://www.secadministrator.com/articles/index.cfm?articleid=39121 Remote Compromise Vulnerability in BadBlue Personal File Sharing Program Matt Murphy discovered a vulnerability in BadBlue Web Based File Sharing Program Personal Edition 1.7 through 2.2 that can let an attacker gain full administrative control of the vulnerable system. This vulnerability is partially the result of the software performing two security checks (i.e., binary replacement of the first two characters in the requested file extension and the requirement that requests to access .hts files be submitted by 127.0.0.1 and contain a proper 'Referer' header) in the wrong order. BadBlue has released version 2.3, which isn't vulnerable to this condition. http://www.secadministrator.com/articles/index.cfm?articleid=39092 ==== 3.

(contributed by Jan De Clercq, jan.declercqat_private) A. Sometimes users receive the error message "You do not have permission to change your password." Upon investigation, you might find that only the Administrator account could change the password. Windows NT 4.0 displays this error message if both of the following items are selected in the User Manager for Domains utility: "User Must Change Password at Next Logon" in the user account properties and "User must log on in order to change password" in the account policies. The administrator can resolve this problem by resetting the user account's password or by clearing the "User must log on in order to change password" option. By default, NT Server 4.0 doesn't have the "User must log on in order to change password" option selected. For more information about these particular configuration settings, read the explanation on our Web site. http://www.secadministrator.com/articles/index.cfm?articleid=25024 ==== 6.
