-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 INTERNET RISK UPDATE for 04-25-2002 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: According to several sources, U.S. intelligence officials are warning of possible cyber-attacks on U.S. and Taiwanese computer networks by both Chinese military and students in the next few weeks. Officials are concerned that the planned attacks are aimed at damaging and/or disrupting computer systems through the use of Internet hacking and computer viruses. VIRUSES/WORMS: Nothing new to report this morning other than a few nuisances and socially engineered-type viruses. Good time to update your anti-virus solution of choice. ******************************************** RECOMMENDATIONS ******************************************** For further information regarding the U.S. intelligence officials warning, please refer to the following articles: http://www.siliconvalley.com/mld/siliconvalley/313 2466.htm http://www.latimes.com/news/nationworld/world/la-0 42502china.story For a list of current vulnerabilities, please see: https://gtoc.iss.net/vulnerabilities.php 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 45.37% Unauthorized Access Attempt 26.20% Denial Of Service 14.76% Suspicious Activity 10.37% Pre-Attack Probe 03.16% Back Door 00.14% ******************************************** 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) 79.58% 22 (ssh) 05.60% 161 (SNMP) 04.86% 25 (smtp) 02.62% 1028 (unassigned) 02.60% 21 (ftp) 01.79% 1500 (ADSM/TSM) 01.01% 15104 (unassigned) 00.71% 6723 (unassigned) 00.64% 515 (lp,lpr,printer) 00.58% ******************************************** BACKGROUND, COPYRIGHT NOTICE, and DISCLAIMER ******************************************** Background.
