-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 INTERNET RISK UPDATE for 04-26-2002 ISS X-Force Internet Threat Intelligence Center www.iss.net - Click on AlertCon logo for more information. ******************************************** ALERTCON 1 Projected: AlertCon 1 ******************************************** ALERTCON 1 - We are at AlertCon 1, the usual chaotic state of the Internet. Vulnerabilities: A new CIA report makes it clear that U.S. intelligence analysts have become increasingly concerned that authorities in Beijing are actively planning to damage and disrupt U.S. computer systems through the use of Internet hacking and computer viruses. Microsoft has advised of a vulnerability in Outlook 2000 and 2002. The impact is that an attacker could run code of his choice. Microsoft has rated this risk as moderate. VIRUSES/WORMS: W32/Klez-G, I-Worm.Klez.h, I-Worm.W32/Klez.gen@MM, and W32.Klez.H@mm. This memory-resident variant of the WORM_KLEZ.A mass-mailing worm uses SMTP to propagate via email. The subject line of the email it arrives with is randomly selected from a list of possible choices. ******************************************** RECOMMENDATIONS ******************************************** For further information on the CIA report, please visit the link below. Again, we would strongly recommend that businesses and SOHO users ensure that their systems have the latest operating system, application and anti-virus patches. The miscreants continue to target known, unpatched, vulnerabilities. http://www.iht.com/articles/55860.html For a patch for Outlook 2002 and 2002, please see: <http://www.microsoft.com/technet/treeview/default .asp?url=/technet/security/bulletin/MS02-021.asp> For a list of current vulnerabilities, please see: https://gtoc.iss.net/vulnerabilities.php For further information on Klez, please refer to: <http://www.antivirus.com/vinfo/virusencyclo/defau lt5.asp?VName=WORM_KLEZ.H> Information regarding viruses and worms please see: https://gtoc.iss.net/viruses.php RealSecure� Network Sensor X-Press Update 4.3 is now available from the ISS Download Center: http://www.iss.net/download/ ******************************************** FACTOID: Some PDA devices function as a cellular phone, pager, or even a laptop replacement, which provides more connectivity and power, but puts users at an increased risk for virus infection. Three viruses have targeted Palm devices: the Liberty Crack Trojan horse and the Phage and Vapor viruses. Remember, your network is only as strong as its weakest point. ******************************************** ATTACK SIGNATURE RANKING - global IDS, midnight - midnight, previous Day, % of total ******************************************** Protocol Decode 54.46% Unauthorized Access Attempt 38.09% Pre-Attack Probe 02.79% Suspicious Activity 02.58% Denial Of Service 02.08% Back Door 00.00% ******************************************** TOP TEN ATTACK DESTINATION PORTS - global IDS, midnight - midnight, previous day, % of top ten (ports found at) http://www.networkice.com/Advice/Exploits/Ports/de fault.htm ******************************************** 80 (http) 87.27% 161 (SNMP) 03.23% 139 (NetBIOS) 02.23% 21 (ftp) 02.03% 162 (SNMPTrap) 02.01% 69 (tftp) 01.21% 22 (ssh) 00.87% 25 (smtp) 00.46% 6768 (unassigned) 00.36% 23 (telnet) 00.33% ******************************************** BACKGROUND, COPYRIGHT NOTICE, and DISCLAIMER ******************************************** Background.
