INTERNET RISK UPDATE for 07-10-2002 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 chaotic, unregulated state of the Internet. The newly established X-Force(tm) Threat Analysis Service (XFTAS) enables proactive security management through comprehensive evaluation of global online threat conditions and detailed analyses tailored for specific customer needs. The service provides a unique blend of threat information collected from Internet Security System's international network of Security Operations Centers and trusted security intelligence from the X-Force research and development organization. This powerful combination clearly denotes the nature and severity of external Internet threats. Daily summaries provide current and forecast assessments for active vulnerabilities, viruses/worms and threats, including links to recommended fixes and security advice. Please take a tour of the new service at: http://xforce.iss.net/index.php VULNERABILITIES: We are seeing a marked increase in RPC (Port 111) scans. The Apache vulnerability is still problematic if not correctly patched. VIRUSES/WORMS: W32/Liac@MM - This email worm is written in Visual Basic and uses Microsoft Outlook to mail itself to all recipients in the Outlook contacts list. Upon execution, the following fake error message is displayed: Error54: Media Player not installed correctly ******************************************** RECOMMENDATIONS ******************************************** Apache: The X-Force has released an advisory with patching instructions for the default setting of the Apache HTTP Server. This advisory requires immediate action on behalf of all system users with Apache HTTP Server. See Apache for additional details. http://bvlive01.iss.net/issEn/delivery/xforce/alertdetail.jsp?oid=20524 http://httpd.apache.org/info/security_bulletin_20020617.txt ******************************************** BACKGROUND, COPYRIGHT NOTICE, and DISCLAIMER ******************************************** Background. We provide this information in the spirit of PDD 63 to help security professionals wage the war against Internet threats more effectively. Information in this update derived primarily from global, real time, 24 x 7 IDS feeds, ISS X-Force R&D Team research, and professional liaison. Other sources as noted. AlertCon 1 - Internet risk baseline reflecting the malicious, determined, global, 24/7 attacks experienced by all networks connected to the Internet. In simple terms, AlertCon 1 indicates that a newly configured computer will be compromised within 24 hours of first being connected to the Internet. AlertCon 2 means increased vigilance is necessary. The potential exists for increased risk because of new vulnerabilities or credible threats to the confidentiality, integrity, and/or availability of computer networks. Some degree of vulnerability assessment and potential corrective action is recommended. AlertCon 3 reflects focused attacks. Internet attacks have been noted against specific vulnerabilities or inherent information system weaknesses. Immediate defensive action is required. AlertCon 4 means an actual or potentially catastrophic security situation has arisen within a network or group of networks whose survival depends on immediate and focused defensive action. This condition may be imminent or ongoing. All summaries cover 24 hours the previous workday, GMT. Monday summaries may cover some weekend activity. Copyright 2002 Internet Security Systems, Inc.
