INTERNET RISK UPDATE for 06-12-2002 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, the normal chaotic state of the Internet. VULNERABILITIES: Microsoft: Two newly discovered vulnerabilities affecting Internet Explorer have been published, both of which could enable an attacker to spoof trusted web sites. The first vulnerability involves the way digital certificates from web servers are validated. The second vulnerability could enable a web page to display the URL from a different web site in the IE address bar. VIRUSES/WORMS: A Klez-related hoax has been circulating across the Internet. This socially engineered e-mail message claims to have an anti-Klez program attached to it and appears to come from Kaspersky Labs, an antivirus company. The subject line of the message is, "You're under a serious threat!" The text reads, "Kaspersky Labs urging users to take the necessary measures to protect themselves against the mounting threat from the latest version of the Internet-worm Klez, most users lightly regarded the problem of securing their personal data, resulting in a global Internet virus epidemic. Over the past several days our technical support services have received over twelve thousand inquiries concerning Klez Internet worm infections." The message is a hoax and the attached file is actually a remote-administration Trojan (RAT) called Smokedown. ******************************************** RECOMMENDATIONS ******************************************** Microsoft has provided Patches for the "gopher" vulnerability for Internet Explorer 5.01 and 5.05. These vulnerabilities can be eliminated either by installing the patch or upgrading to an unaffected version. <http://www.microsoft.com/technet/treeview/default.asp?url=/technet/security /bulletin/MS01-027.asp> For a list of current vulnerabilities, please see: https://gtoc.iss.net/vulnerabilities.php For full details on the Klez hoax, please see: http://www.kaspersky.com/news.html?tnews=20146&id=700915 Information regarding viruses and worms please see: https://gtoc.iss.net/viruses.php ******************************************** FACTOID: About one-third of the readers who responded to a recent survey by CNET News.com picked security as the niche where information technology spending would most increase. Services and consulting software came in second. In addition, only 2 percent of respondents said that their companies would decrease spending in security-related applications. One in three said that they expected to spend less on enterprise software. ******************************************** ATTACK SIGNATURE RANKING - global IDS, midnight - midnight, previous Day, % of total ******************************************** Suspicious Activity 33.92% Protocol Decode 28.99% Unauthorized Access Attempt 21.24% Denial Of Service 08.59% Pre-Attack Probe 07.23% 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-ports.html ******************************************** 80 (http) 71.20% 25 (smtp) 09.00% 23 (telnet) 07.15% 21 (ftp) 03.83% 69 (tftp) 03.14% 1433 (SQL) 02.11% 161 (SNMP) 01.04% 22 (ssh) 00.93% 515 (printer) 00.86% 53 (DNS) 00.74% ******************************************** BACKGROUND, COPYRIGHT NOTICE, and DISCLAIMER ******************************************** Background.
