Various organizations have held hacking contests in the past, some with prize incentives and some without. In 1999, Microsoft hosted a contest to break into Windows 2000, and this year, the company launched another contest to hack the new Windows XP OS. Neither contest offered prizes for winners. To counter Microsoft's Win2K contest, the PowerPC Linux Project (LinuxPPC) launched its own hacking contest in 1999; the winner got to keep the LinuxPPC server that hosted the contest. In January 2001, the Honeynet Project hosted a forensic challenge to see who could determine how a hacker broke in to a system by examining the supplied forensics data. The prize for successful detectives was a copy of the great book, "Hacking Exposed." And just last week, Argus Systems launched a challenge to see who could break into its PitBull security product. The company offered $30,000 to the winner, and a group of Polish hackers took the prize quickly. See the related news item in the SECURITY ROUNDUP section below. Thirty thousand dollars is a lot of money, especially when the winners earned it by hacking into one system over the course of a few days. On the other hand, Argus gained incredibly useful insight about how its product and the system it runs on might be vulnerable to attack. So the money is well spent in my opinion. This week, I learned about a new contest that takes prize offerings to an entirely new level. All you have to do is break the security of Saafnet's upcoming AlphaShield 2000 product--and win a cool $1 million cash. AlphaShield 2000 is Saafnet's soon-to-be-released $149 USB add-on that introduces security by virtually disconnecting the system from the Internet while the user isn't actively receiving data. The product targets home users and small-business networks. The technology's premise is that without an active virtual connection, an intruder can't reach the system. Sounds interesting. Each time someone launches a hacking challenge, I never wonder whether someone will win the challenge; I wonder how much time it will take. Information security technologies have never been 100 percent unbreakable for various reasons, so it stands to reason that someone will eventually win any security hacking challenge. And even though Saafnet's technology sounds strong, it's unproven; I tend to think a chink exists in the armor somewhere. We'll have to wait and see. But even if no one wins the million-dollar prize money, we should still err on safety's side and assume that the technology has a chink somewhere. I'm not sure when Saafnet ( http://www.saafnet.com ) will officially launch the challenge, but I'll let you know when I hear about a launch date. Until next time, have a great week. Sincerely, Mark Joseph Edwards, News Editor markat_private 2. ========== SECURITY RISKS ========= (contributed by Mark Joseph Edwards, markat_private) * ROBTEX VIKING WEB/PROXY SERVER RELATIVE PATH VULNERABILITY A vulnerability exists in the RobTex Viking Web/Proxy Server that lets an attacker break out of the Web root by using relative paths. For example, an attacker can gain access to files outside of the Web root directory by connecting to a vulnerable host and issuing the command http://
>/\...\<file outside of Web root>. The vendor, RobTex, has released build 378 that corrects this problem. http://www.windowsitsecurity.com/Articles/Index.cfm?ArticleID=20873 * BUFFER OVERFLOW CONDITION IN IPSWITCH IMAIL 6 eEye Digital Security discovered that a vulnerability exists in the IPSwitch IMail 6.06 mail server that can let a remote attacker gain system-level access to servers running the SMTP daemon. This vulnerability exists because the IMail SMTP daemon doesn't perform proper bounds checking on the input data that passes to the IMail Mailing List handler code. IPSwitch has released a patch to correct this vulnerability. http://www.windowsitsecurity.com/articles/index.cfm?articleID=20851 ******************** >>>> SPONSOR: ...15 MIN. LATER HE WAS IN THE PRINCIPAL'S OFFICE! <<<< A high school network administrator installed Event Log Monitor on classroom servers to evaluate system performance. The next day, ELM alerted him that a student was trying to break into the system. Within 15 minutes, the would-be hacker was in the Principal's office waiting for his parents to arrive. Use Event Log Monitor to keep tabs on your security perimeter. Because these aren't the only computers teenagers like to hack into.

Find out which viruses could threaten your systems when you're not looking. Check it out! http://www.windowsitsecurity.com/Panda/Index.cfm 4. ==== SECURITY ROUNDUP ==== * NEWS: W3C RELEASES WORKING DRAFT FOR XML ENCRYPTION The World Wide Web Consortium (W3C) has released a working draft of a new standard for encrypting XML-based documents. The organization published the document, "XML Encryption Requirements," April 20, 2001. According to the draft, W3C will design encryption methods to protect all or parts of an XML-based document using existing encryption specifications, such as Advanced Encryption Standard (AES) and Triple Data Encryption Standard (3DES). http://www.windowsitsecurity.com/Articles/Index.cfm?ArticleID=20863 * NEWS: FUNLOVE VIRUS INFECTS MICROSOFT HOTFIXES Microsoft stopped all access to its hotfixes this week when someone discovered that many of the hotfixes contained the FunLove virus, which first appeared in November 1999. The virus infects Windows-based portable executable documents, ActiveX controls (.ocx files), and screen saver files. When FunLove runs on a Windows NT system, the virus grants Administrator rights to any user who logs on. http://www.windowsitsecurity.com/Articles/Index.cfm?ArticleID=20864 * NEWS: POLISH HACKERS TAME PITBULL Argus Systems, makers of the PitBull security software for Solaris, planned to highlight its 5th Argus Hacking Challenge at the Infosecurity Europe conference this week in London. However, a group of Polish hackers broke in to the system, effectively winning the challenge before Argus ever made it to the conference. http://www.windowsitsecurity.com/Articles/Index.cfm?ArticleID=20844 * REVIEW: USERMANAGEMENT 5.3 PROFESSIONAL AND IMPORT Windows 2000 and Windows NT include easy-to-use graphical functions to help you create, modify, and delete user accounts. However, both products lack the flexibility to manage large user numbers. Tools4ever's UserManagemeNT 5.3 product suite includes powerful enterprise-class NT utilities that let you manage user-account and user-resource creation, movement, and deletion from within any configured domain. You can also use the product with Win2K. Learn all about it in Marty Scher's review on our Web site. http://www.win2000mag.com/Articles/Index.cfm?ArticleID=20392 5. ==== SECURITY TOOLKIT ==== * BOOK HIGHLIGHT: INTRUSION SIGNATURES AND ANALYSIS By Stephen Northcutt, Mark Cooper, Matt Fearow, and Karen Federick List Price: $39.99 Fatbrain Online Price: $31.99 Softcover, 408 pages Published by New Riders Publishing, January 2001 ISBN 0735710635 For more information or to purchase this book, go to http://www1.fatbrain.com/asp/bookinfo/bookinfo.asp?theisbn=0735710635 and enter WIN2000MAG as the discount code when you order the book. * VIRUS CENTER Panda Software and the Windows 2000 Magazine Network have teamed to bring you the Center for Virus Control.

The worm renames several existing .vxd files and then creates copies of itself using the original file names. http://18.104.22.168/panda/index.cfm?FuseAction=Virus&VirusID=1087 Virus Alert: W32/Hello W32Hello is a worm that propagates through Microsoft's MSN Messenger program. The worm is written in Visual Basic (VB) 5.0. The file that contains the worm is 10KB and has no icon. http://22.214.171.124/panda/index.cfm?FuseAction=Virus&VirusID=1085 * FAQ: HOW DO I ENTER A SHUTDOWN DESCRIPTION FROM THE COMMAND LINE? ( contributed by John Savill, http://www.windows2000faq.com ) In Windows XP, the new version of shutdown.exe (the tool used to shutdown/reboot from the command line) contains support for tracker descriptions via the -d (description/reason code) and -c (comment) attributes. For example, the command shutdown -t 10 -d up:125:1 -c "Testing" shuts down the system in 10 seconds, with a description of user-defined, planned, major reason 125, minor reason 1, and a comment of "Testing." * WINDOWS 2000 SECURUTY: INTERNET EXPLORER SECURITY OPTIONS, PART 3 Because Web browsing provides so many ways for malicious users to attack your workstations and internal network, make sure your users don't expose your systems to risk while they browse the Web. In Part 1 and Part 2, Randy Franklin Smith described security zones and settings in Microsoft Internet Explorer (IE) 5.0. In Part 3, Randy shows you the IE security settings that let you control cookies and file downloads.
