-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 INTERNET RISK UPDATE for 05-28-2002 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 have returned to AlertCon 1, but please be cognizant of the threat still posed by the MS SQL Worm. Vulnerabilities: Mandrake's imap has a reported buffer overflow that could allow a malicious user to run code on the server with the uid and gid of the email owner. A mitigating factor is that the attacker must successfully authenticate to the imap service in order to exploit it. Microsoft has released an advisory that addresses a flaw in the authentication mechanism for the debugging facility that may allow unauthorized access to the debugger. The debugger performs diagnostic and analytic functions on applications as they are running on the operating system. VIRUSES/WORMS: MS SQL Worm: We continue to observe a strong presence of this worm. An analysis confirms that there are two separate worms with distinctively different data packages actively propagating via port 1433. Once a system is compromised by using the default administrator settings in SQL Server 7.0 and 2000, it adds a temporary account to the local group administrator's list and then executes a Java Script using a third party e-mail program which sends a password file and then the victims network configuration settings to [EMAIL PROTECTED] JS/NoClose is a JavaScript Trojan. When an affected website is accessed the Trojan will minimize Internet Explorer and attempt to access other websites without the user's express permission. These sites either contain advertisements or pornographic material. ******************************************** RECOMMENDATIONS For information on the Mandrake advisory, please refer to: http://linuxtoday.com/news_story.php3?ltsn=2002-05-28-010-26-SC-MD For information on the Microsoft advisory, please refer to: <http://www.microsoft.com/technet/treeview/default.asp?url=/technet/se curity/bulletin/MS02-024.asp> For a list of current vulnerabilities, please see: https://gtoc.iss.net/vulnerabilities.php For information on the MY SQL Worm, please refer to: http://www.antivirus.com/vinfo/virusencyclo/default5.asp?VName=BAT_SQL SPIDA.B For information on the NoClose Trojan, please refer to: http://www.sophos.com/virusinfo/analyses/jsnoclose.html Information regarding viruses and worms please see: https://gtoc.iss.net/viruses.php ******************************************** FACTOID: State courts authorized a dramatic increase in the use of electronic surveillance last year, mostly to listen in on cell phones, pagers and other wireless devices, according to a government report released. In its annual Wiretap Report, the Administrative Office of the U.S. Courts said state courts approved 1,005 wiretap applications last year, up from 711 in the previous year. ******************************************** ATTACK SIGNATURE RANKING - global IDS, midnight - midnight, previous Day, % of total ******************************************** Protocol Decode 41.84% Unauthorized Access Attempt 31.23% Suspicious Activity 18.82% Denial Of Service 04.98% Pre-Attack Probe 03.11% Back Door 00.03% ******************************************** 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-ports.html ******************************************** 80 (http) 77.05% 25 (smtp) 07.41% 161 (SNMP) 05.78% 69 (tftp) 02.30% 1433 (SQL) 02.23% 53 (DNS) 01.57% 21 (FTP) 01.23% 139 (NetBIOS) 00.92% 1214 (KAZAA) 00.83% 143 (imap) 00.68% ******************************************** BACKGROUND, COPYRIGHT NOTICE, and DISCLAIMER ******************************************** Background.
