INTERNET RISK UPDATE for 04-09-2002
ISS X-Force Internet Threat Intelligence Center

www.iss.net - Click on AlertCon logo for more information.

********************************************
ALERTCON 1
Projected: AlertCon 1 (next 48 hours)
********************************************

ALERTCON 1 - AlertCon 1 reflects the malicious, determined, global,
24 x 7 attacks experienced by all networks. The risk at AlertCon 1 means
that an unprotected computer running common commercial software will be
compromised in a day after connecting it to the Internet.

Vulnerabilities: There are two new vulnerabilities from Microsoft -
        1. Opening group policy files for exclusive read blocks policy
application. Affected software: Windows 2000 Server, Windows 2000 Advanced
Server, and Windows 2000 Datacenter Server.
        2. Unchecked buffer in the Multiple UNC Provider could enable
code execution. Affected software: NT 4.0 Workstation, NT 4.0 Server, NT
4.0 Server, Enterprise Edition, NT 4.0 Terminal Server Edition, Windows 2000
Professional, Windows 2000 Server, Windows 2000 Advanced Server, and Windows
XP Professional.

VIRUSES/WORMS: APLORE.A is another nuisance worm, like graffiti on a wall.
When the worm is executed it remains in resident memory and sends messages
regarding pornography via Internet Relay Chat (IRC).

Internet Security Systems has released its Internet Risk Impact Summary for
December 22, 2001 through March 21, 2002. Please click on this link

Information regarding viruses and worms please see:

********************************************

FACTOID: Financial losses from cyber crimes shot up for the third year in a
row. Ninety percent of respondents detected computer security breaches
within the past 12 months. See the full report at

********************************************
ATTACK SIGNATURE RANKING - global IDS, midnight - midnight, previous
Day, % of total
********************************************

Suspicious Activity 48.26%
Unauthorized Access Attempt 17.06%
Protocol Decode 15.49%
Pre-Attack Probe 14.04%
Denial Of Service 05.13%
Back Door 00.02%

********************************************
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) 53.35%
21 (ftp) 26.60%
161 (SNMP) 08.48%
23 (telnet) 03.67%
69 (tftp) 02.33%
162 (SNMPTrap) 01.91%
25 (smtp) 01.23%
22 (ssh) 00.85%
1500 (VLSI) 00.84%
139 (NetBIOS) 00.75%

Yesterday's port 80 hits are lower than normal but still show better than
half of all our malicious activity coming in through the wide open http
port. Unless the firewall policy is taking this into consideration by adding
additional blocks your firewall is marginalized by all this port 80 traffic.
