Are you ready for more security statistics? Newly published information indicates that Linux systems suffered an increasing number of attacks in the first half of 2002, compared with 2001. According to London company mi2g, Linux systems have suffered 7630 attacks so far in 2002, not including viruses and worms. During all of 2001, Linux systems suffered only 5736 attacks. The company said the attacks are largely because of third-party applications with vulnerabilities that administrators don't patch quickly enough. On the other hand, attacks against Microsoft IIS systems have diminished. According to mi2g, attackers launched 9404 attacks against IIS systems in the first half of 2002, compared with 11,828 attacks in the first half of 2001. Overall, however, the number of attacks against all systems rose 27 percent over last year. In the first half of 2001, organizations reported 16,007 attacks; so far this year, organizations have reported 20,371 attacks. Government online systems are experiencing fewer attacks. Fifty-four US government systems reported attacks so far this year, compared with 204 such attacks in the first half of 2001. In the UK, only 12 government systems reported attacks this year, compared with 38 attacks in the first half of 2001. According to mi2g, the US Cyber Security Enhancement Act (CSEA) has probably helped reduce the number of attacks against government systems because the act permits much stiffer penalties for cybercrime. http://www.mi2g.com/cgi/mi2g/press/110702.php The recently published Computer Emergency Response Team (CERT) statistics reflect an increase in the number of vulnerabilities reported this year. According to CERT, organizations have reported 2148 vulnerabilities so far this year, compared with 2437 reported vulnerabilities in 2001 and 1090 reported in 2000. http://www.cert.org/stats/cert_stats.html The Computer Security Institute (CSI) released statistics in April 2002 that CSI gathered in conjunction with the Federal Bureau of Investigation (FBI). CSI polled 503 security practitioners; 80 percent of those polled reported financial losses because of system breaches. Forty-four percent (223 entities) were willing to quantify their losses, which totaled about $455,848,000. http://www.gocsi.com/press/20020407.html Riptech, a Virginia-based security services firm, recently released an interesting set of statistics. Riptech gathered log information from 400 companies in more than 30 countries and confirmed that more than 180,000 attacks took place in the first half of 2002. The report shows that 80 percent of all attacks originate from 10 countries, including the United States, Germany, South Korea, China, France, Canada, Italy, Taiwan, the UK, and Japan. You can read more about Riptech's report in the related news story in the Security Roundup section of this newsletter. http://www.secadministrator.com/articles/index.cfm?articleid=25897 With the exception of a few bright spots, the unsurprising news is that attacks are increasing. Some of the increase might be a function of a trend feeding on itself. For example, more organizations and individuals discover and report more vulnerabilities in some detail. Then, unscrupulous individuals use the details to perpetrate additional attacks. Also, each reported vulnerability--if left unpatched for too long--lets intruders attack an increasing number of systems. Because intruders use search-engine tactics to identify many vulnerable Web servers, the numbers can soar higher. Given the current climate, patch your systems quickly. And take a moment to answer today's Instant Poll question about the security resources you need to keep your organization from becoming a negative security statistic. ~~~~~~~~~~~~~~~~~~~~ ~~~~ SPONSOR: FREE WHITE PAPER: CONTENT FILTERING STRATEGIES ~~~~ Defeat cyber-threats.

The vulnerability can result in remote compromise of the vulnerable system. By sending a specially crafted email to a vulnerable system, an attacker can execute code remotely on that system. Read eEye Digital Security's advisory for a detailed explanation of this vulnerability. NAI has released a patch for the latest version of the PGP Outlook plugin to address this vulnerability. http://www.secadministrator.com/articles/index.cfm?articleid=25875 * BUFFER OVERRUN IN SEMANTIC NORTON PERSONAL SECURITY FIREWALL Ollie Whitehouse of @stake discovered a buffer-overflow vulnerability in Symantec's Norton Personal Firewall that an attacker can exploit to execute code on the vulnerable system. An intruder can exploit this vulnerability even if the requesting application isn't configured in the firewall permission settings to make outgoing requests. See the @stake advisory for a detailed technical explanation. The vendor, Symantec, has released an advisory regarding this vulnerability and recommends that affected users download the patch from the advisory URL when the patch becomes available. http://www.secadministrator.com/articles/index.cfm?articleid=25895 3. ==== ANNOUNCEMENTS ==== (brought to you by Windows & .NET Magazine and its partners) * ENERGIZE YOUR ENTERPRISE AT MEC 2002, OCTOBER 8 THROUGH 11, ANAHEIM, CA Don't miss the essential Microsoft infrastructure conference where you'll connect with a world of expert information, technical training sessions, best practices, and hands-on labs.

The new benchmarking set consists of a scoring tool along with security templates that you can use to analyze and adjust system security settings. http://www.secadministrator.com/articles/index.cfm?articleid=25949 * NEWS: INTERNET SECURITY THREAT REPORT, VOLUME II Riptech released Volume II of its Internet Security Threat Report, which shows that Internet attacks grew at an annualized rate of 64 percent during the period between January 2002 and June 2002. The report is based on data mining and analysis of more than 11 billion firewall logs and Intrusion Detection System (IDS) alerts from more than 400 companies in more than 30 countries around the world. http://www.secadministrator.com/articles/index.cfm?articleid=25897 * FEATURE: *#@$&% SECURITY As you know, securing your networks requires vigilance and a lot of work. However, you ignore security at your peril, risking your job and possibly your company's entire future. But when you adopt the right mind-set, security tasks aren't so bad. What's important is to address security problems before it's too late. http://www.secadministrator.com/articles/index.cfm?articleid=25928 * FEATURE: WMP EULA AND DRM SYSTEM SECURITY On June 27, 2002, Microsoft posted a security update to the Windows Media Player (WMP). That update included an End User Licensing Agreement (EULA) covering, among other things, the Digital Rights Management (DRM) system. http://www.secadministrator.com/articles/index.cfm?articleid=25910 5. ==== INSTANT POLL ==== * RESULTS OF PREVIOUS POLL: CREDIT CARD INFORMATION THEFT The voting has closed in Windows & .NET Magazine's Security Administrator Channel nonscientific Instant Poll for the question, "Have you or has your company experienced credit card information theft through the Internet?"

Visit the site often to remain informed about the latest threats to your system security. http://www.secadministrator.com/panda * VIRUS ALERT: W32/DADINU W32/Dadinu is a worm that spreads by sending itself to every address in the Microsoft Messenger Address Book. The worm creates a large number of files on infected computers. The files are copies of the worm. http://188.8.131.52/panda/index.cfm?fuseaction=virus&virusid=1183 * VIRUS ALERT: W32/CALIL W32/Calil emails itself to every address in the Microsoft Outlook Address Book. The message containing the worm has a subject field that reads "FW:FW: LILAC project video attach." http://184.108.40.206/panda/index.cfm?fuseaction=virus&virusid=1185 * VIRUS ALERT: W32/FRETHEM.K W32/Frethem.K is a worm that spreads through email with a subject that reads "Re: Your password!." This message contains a file attachment called "decrypt-password.exe file." The worm exploits a vulnerability in Microsoft Internet Explorer (IE) 5.5 and IE 5.01 that lets files attached to an email message run automatically simply by viewing the message. http://220.127.116.11/panda/index.cfm?fuseaction=virus&virusid=1187 * FAQ: HOW CAN I REMOVE THE LINK BETWEEN OUTLOOK 2002 AND MSN MESSENGER? ( contributed by John Savill, http://www.windows2000faq.com ) A. By default, Microsoft Outlook 2002 and MSN Messenger are linked. If both applications are running and you attempt to close MSN Messenger, the following error appears on the screen: "There are other applications currently using features provided by Windows Messenger. You must close these other applications before you can exit Windows Messenger. These applications may include Outlook, Outlook Express, MSN Explorer, and Internet Explorer." To remove the link between Outlook 2002 and MSN Messenger, perform the following steps: 1. Start Outlook. 2. From the Tools menu, select Options. 3. Select the Other tab. 4. Clear the "Enable Instant Messaging in Microsoft Outlook" check box in the Instant Messaging section, then click OK. 5.

(One message in this thread) Rich writes that he'll be migrating to a Windows 2000 DHCP server soon. He has a requirement that nonauthorized machines not be allowed on the network. Right now, Rich registers valid media access control (MAC) addresses through DHCP to prevent nonauthorized machines on the network, but performing this task is an administrative nightmare. Rich wants to know whether DHCP performs some other type of machine/user authentication before it issues an IP address so that if the authentication fails, the machine doesn't receive an address on the network. Do you know of any other solution to keep nonauthorized machines off a network?

Because he was running a second domain controller (DC) in the domain, the second controller took over as the root of the forest. He repaired the original domain root and put it back on the network as a DC. However, Eric now keeps receiving Event ID 1000 and Event ID 1202 error messages in the Application log every 5 minutes. He has reapplied the group policy link for the Domain Controller OU, but the error messages still appear. How can he resolve this problem?
