-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 INTERNET RISK UPDATE for 05-07-2002 ISS X-Force Internet Threat Intelligence Center www.iss.net - Click on the AlertCon logo for more information. ******************************************** ALERTCON 2 Projected: AlertCon 2 ******************************************** ALERTCON 2 - We are at AlertCon 2, a heightened state of awareness, to re-emphasize patching efforts in the wake of the potentially dangerous exploit listed below. Vulnerabilities: Critical Exploit warning: Exploit code for the Microsoft IIS vulnerability discussed in the April 10, 2002 X-Force Alert has been posted to the Internet. ISS expects this exploit code will be enhanced to include a more destructive payload and worm-like propagation capabilities in the near future. The Microsoft Security Bulletin MS02-018 has been updated. VIRUSES/WORMS: As we mentioned yesterday, the Klez worm is showing remarkable stamina, having surfaced early last year. Its resilience is a testimony to the craftiness of its author(s) and the inability of users to come to grips with basic security awareness. There are reports that an older virus, Chernobyl, has resurfaced and is piggybacking on Klez. It's always a good time to update your antivirus solution of choice and stress user policies. ******************************************** RECOMMENDATIONS ******************************************** For further information on the Microsoft IIS vulnerability, please refer to: http://www.iss.net/security_center/alerts/advise11 4.php ISS X-Force recommends defensive vulnerability scans be initiated immediately and determine systems still requiring application of the Microsoft patch: <http://www.microsoft.com/technet/treeview/default .asp?)url=/technet/security/bulletin/MS02-018.asp> For a list of current vulnerabilities, please see: https://gtoc.iss.net/vulnerabilities.php For further information on the Klez worm, please see: http://vil.nai.com/vil/content/v_99455.htm Information regarding viruses and worms please see: https://gtoc.iss.net/viruses.php ******************************************** ATTACK SIGNATURE RANKING - global IDS, midnight - midnight, previous Day, % of total ******************************************** Protocol Decode 40.97% Unauthorized Access Attempt 32.21% Suspicious Activity 15.54% Pre-Attack Probe 07.50% Denial Of Service 03.75% Back Door 00.02% ******************************************** 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) 48.37% 21 (ftp) 34.48% 161 (SNMP) 07.61% 25 (smtp) 02.56% 69 (tftp) 02.23% 162 (SNMPTrap) 01.22% 515 (lp,lpr) 01.08% 1500 (ADSM/TSM) 00.94% 22 (ssh) 00.93% 139 (NetBIOS) 00.59% ******************************************** BACKGROUND, COPYRIGHT NOTICE, and DISCLAIMER ******************************************** Background.
