-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 INTERNET RISK UPDATE for 05-14-2002 ISS X-Force Internet Threat Intelligence Center www.iss.net - Click on the AlertCon logo for more information. ******************************************** ALERTCON 1 Projected: AlertCon 1 ******************************************** ALERTCON 1 - We are at AlertCon 1, the usual unregulated chaos on the Internet. Vulnerabilities: Multiple personal firewalls for Microsoft Windows platforms, including Tiny Personal Firewall and AtGuard Personal Firewall, could allow a remote attacker to bypass the firewall using port 53. If a DNS server has not been defined in configuration, an attacker could create a Trojan that uses port 53 to bypass the firewall. An attacker can use this vulnerability to send/receive messages, including sensitive information without the user knowing it. VIRUSES/WORMS: JDBGMGR hoax - This email message is just a HOAX. Although, the JDBGMGR file may become infected by a number of valid viruses (most commonly W32/Magistr@MM), the details of this HOAX message are not based on actual events. We are advising users who receive the email to delete the message and DO NOT pass it on, as this is how an email HOAX propagates. ******************************************** RECOMMENDATIONS ******************************************** For the firewall vulnerability, as a workaround, change the default DNS to a fixed host and refer to: http://www.iss.net/security_center/static/9063.php For a list of current vulnerabilities, please see: https://gtoc.iss.net/vulnerabilities.php For information on the JDBGMGR Hoax, please refer to: http://vil.nai.com/vil/content/v_99436.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 35.78% Unauthorized Access Attempt 25.49% Suspicious Activity 20.03% Denial Of Service 11.91% Pre-Attack Probe 06.74% Back Door 00.05% ******************************************** TOP TEN ATTACK DESTINATION PORTS - global IDS, midnight - midnight, previous day, % of top ten (ports found at) http://www.neohapsis.com/neolabs/neo-ports/neo-por ts.html ******************************************** 80 (http) 68.98% 161 (SNMP) 13.52% 25 (smtp) 05.28% 69 (tftp) 02.87% 162 (SNMPTrap) 02.44% 23 (telnet) 02.38% 1500 (ADSM/TSM) 01.62% 139 (NetBIOS) 01.58% 5050 (mmcc) 00.69% 21 (ftp) 00.64% ******************************************** BACKGROUND, COPYRIGHT NOTICE, and DISCLAIMER ******************************************** Background.
