-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 INTERNET THREAT UPDATE for 01-15-2002 ISS X-Force Special Operations Group www.iss.net - Click on 'Current Internet Threat' for more information. ****************************************************** ALERTCON 1 Projected: AlertCon 1 ****************************************************** ALERTCON 1 - AlertCon 1 reflects the malicious, determined, global, 24 x 7 attacks experienced by all networks. CODE RED VARIANT: Our Global Sensor database indicates an increase in a new variant of the Code Red worm. Many systems have been brought on-line since the initial outbreak last summer and are vulnerable if the recommendations listed below are not followed. LINUX: A vulnerability has been found in the XChat IRC client that allows an attacker to take over the user's IRC session. UNIX: A vulnerability in the Common Desktop Environment (CDE) discovered by the ISS X-Force in November, has recent scanning activity and an exploit is said to be in the wild. VIRUSES/WORMS: Two viruses are on the scope today. WM97/Fifteen-A is a Word macro virus which, on the 15th and 30th of any month, will password protect infected documents with the password. The Trojan.Badcon is a Trojan horse that can cause unpatched Win 95/98/98SE systems to crash and force a restart. The Trojan may present itself as a valid program, such as X-Box emulation software. Closely monitor your anti-virus vendor for up-to-date solutions for current threats on a daily basis. FACTOID: According to CERT/CC the latest set of figures documenting security incidents show 52,658 incidents were reported in 2001 compared to 21,756 in 2000. CERT/CC, hosted by Carnegie Mellon University, was set up in 1988 at the behest of the U.S. Government to coordinate communications during security emergencies. There were 6 incidents reported that year. COMMENTARY: With respect to the hefty rise in reported security incidents in 2001, one can only surmise how many incidents were not reported. With the economy teetering over the abyss it is opined that the number of intrusions into private and public networks that went unreported, far exceeded those that were reported. Consider becoming involved with InfraGard, an alliance between the public and private sectors as well as academia for the sharing of information regarding cybercrime and vulnerabilities. Visit their site at www.InfraGard.net. For information regarding the reporting of cybercrime, please see an an excellent article published last June in 'CIO Magazine', http://www.cio.com/archive/060101/fbi.html. - ------------------------------------------------------ RECOMMENDATIONS - ------------------------------------------------------ For the Netscape vulnerability, please refer to: http://www.securiteam.com/securitynews/5VP0C0A60A.html Regarding the Code Red variant, we recommend defensive vulnerability scans be initiated and vendor patches be applied. Current anti-virus solutions should detect this variant with existing signatures. X-Force Advisory regarding the UPnP and IE 5.5 and 6.0 issues see: http://xforce.iss.net/alerts/advise107.php http://xforce.iss.net/alerts/advise106.php For the Debian Advisory and solution, please see: http://www.linuxsecurity.com/advisories/debian_advisory-1802.html Information regarding the exploitation of the vulnerability in the CDE, please see: http://xforce.iss.net/alerts/advise101.php http://www.cert.org/advisories/CA-2002-01.html For information regarding the WM97/Fifteen-A virus please see: http://www.sophos.com/virusinfo/analyses/wm97fifteena.html Regarding the Trojan.Badcon, please see: http://securityresponse.symantec.com/avcenter/venc/data/trojan.badcon. html For an excellent home/small office firewall solution, please see: http://www.networkice.com/ For information on removing infected executable files, refer to: http://www.sophos.com/support/faqs/filvir.html For other current worms and viruses moving across the Internet see: https://gtoc.iss.net/secure/viruses.php http://www.antivirus.com/vinfo/ - ------------------------------------------------------ ATTACK SIGNATURE RANKING - global IDS, midnight - midnight, previous Day, % of total - ------------------------------------------------------ Unauthorized Access Attempt 48.37% Denial Of Service 24.63% Protocol Decode 18.23% Suspicious Activity 04.92% Pre-Attack Probe 03.78% Back Door 00.07% - ------------------------------------------------------ TOP TEN ATTACK DESTINATION PORTS - global IDS, midnight - midnight, previous day, % of top ten (ports found at) http://www.networkice.com/Advice/Exploits/Ports/default.htm - ------------------------------------------------------ 80 (http) 81.90% 25 (smtp) 03.69% 1214 (unassigned) 03.31% 21 (ftp) 03.27% 443 (ssl) 02.60% 515 (lp,lpr,printer) 01.65% 22 (ssh) 01.47% 69 (tftp) 00.94% 53 (DNS) 00.62% 139 (NetBIOS) 00.56% - ------------------------------------------------------ BACKGROUND, COPYRIGHT NOTICE, and DISCLAIMER - ------------------------------------------------------ Background.
