VIRUS ALERT: COMPUTER ASSOCIATES CALLS "Nimda" WORM A HIGH-RISK THREAT
Get the latest virus info & updates ASAP:
Win32.Nimda worm (Also known as W32/Nimda@MM <mailto:W32/Nimda@MM> )
Win32.Nimda worm (Also known as W32/Nimda@MM <mailto:W32/Nimda@MM> )
Nimda.A is an Internet worm spreading via a number of different methods and
exploiting several known vulnerabilities in Internet Explorer and IIS
systems. It also works as a file virus infecting Win32 Portable Executable
programs as well as files with extensions: html, htm, asp.
This worm may enter a system in the following ways:
* via an HTML e-mail with a specifically constructed MIME header;
* by visiting a Web site hosted on an infected system;
* via open network shares;
* via unpatched IIS systems (both 4.0 and 5.0).
When a user views an HTML e-mail carrying the worm or visits an
infected Web site, Internet Explorer may launch the attached program
executing the Nimda.A code (from the program: readme.exe). This is due to
the "Incorrect MIME Header" vulnerability in Microsoft Internet Explorer
5.01 and 5.5. For a detailed description of this security hole and links to
the appropriate patches, please visit:
The worm may also exploit the following HTTP security loopholes in
systems running Microsoft IIS:
* Microsoft IIS 4.0/5.0 File Permission Canonicalization Vulnerability
* Microsoft IIS/PWS Escaped Characters Decoding Command Execution
* Microsoft IIS and PWS Extended Unicode Directory Traversal
The worm finds vulnerable Internet Servers via randomly selected IP
addresses. The address generation and scanning is performed by the process
named mmc.exe (the file mmc.exe is overwritten by the worm with its own
copy). Users of affected Win NT/2000 systems may experience a significant
deterioration of their system performance when the mmc.exe process is
running. Additionally the worm copies itself as Admin.dll to the root
directories of all accessible drives (the worm marks Admin.dll as a true
Once the worm gets access to a victim machine's files, it searches all
directories and infects htm, asp and html files by adding a one line
worm drops its own code in the MIME format as readme.eml or readme.nws. The
worm is executed from within these MIME files when an infected htm* or asp
file is opened.
The worm infects Win32 PE programs (except Winzip32.exe) by prepending its
code and modifying its resources so that the infected programs use the same
icons as the original programs.
On affected Win9x systems, in order to run on the next reboot, the worm
copies itself as load.exe into the Windows System directory and modifies the
Shell=explorer.exe load.exe -dontrunold
Nimda.A may also copy itself under the name used by one of the legitimate
Microsoft libraries; riched20.dll.
In order to avoid infection by browsing infected web pages Active Scripting
can be disabled in Internet Explorer.
Detection for this virus/worm has been added to the following virus
engine/virus signature combination. Install this update or later to ensure

HappyTime Virus Warning:
Due to the increased number of submissions, the threat level for this worm has been upgraded from 3 to 4.
VBS.Haptime.A@mm is a Visual Basic Script (VBS) worm. It infects .htm, .html, .vbs, .asp, and .htt files. It replicates using MAPI objects to spread itself as an attachment. Also, the worm attaches itself to all outgoing messages using the stationery feature of Outlook Express.
The worm utilizes a known Microsoft Outlook Express security hole so that the worm is executed without having to run any attachment.
Microsoft has patched this security hole that eliminates security vulnerabilities in "Scriptlet.TypLib" ActiveX controls . The patch is available at: http://www.microsoft.com/technet/ie/tools/scrpteye.asp
If you have a patched version of Outlook Express, this worm will not work automatically.

CodeRed.v3 Virus Warning:
CodeRed.v3 was discovered on August 4, 2001. It has been called a variant of the original CodeRed Worm because it uses the same "buffer overflow" exploit to propagate to other web servers. Symantec AntiVirus Research Center received reports of a high number of IIS web servers that were infected. CodeRed.v3 is considered to be a high threat. The original CodeRed had a payload that causes a Denial of Service attack on the White House Web server. CodeRed.v3 has a different payload that allows the hacker to have full remote access to the Web server. For more information - click here.

MsWorld Virus Update:
Borrowing from the success of NakedWife, a new worm, MsWorld, displays a Flash window illustration while mass mailing everyone you know and attempting to reformat your C: drive. MsWorld (W32.MsWorld@MM) hails from Great Britain and at this time, it has not spread very far or very fast. Since it can clog e-mail servers and damage users' root drive files, MsWorld ranks as a 6 on the ZDNet Virus Meter.
How it works
MsWorld arrives as an e-mail with the following information:
Subject: Miss World
Body: Hi, (your name)
Enjoy the latest pictures of Miss World from various Country
If a user clicks on the attached file, a Flash window appears that displays a cute animal and big cake with a single candle. The text, "I fall more in love with you each day!", appears in script at the bottom of the window. While this image displays, MsWorld sends copies of itself to all address found in Outlook's address book.
MsWorld adds the following to the infected computer's Autoexec.bat, which causes the computer to reformat the C: drive whenver it is next rebooted:
Echo "This Everything for my Girl Friend.........,
(CatEyes, KRSSL, SS Hostel) "
Format C: /q /autotest
MsWorld also attempts to delete the files USER.DAT, USER.DA0, SYSTEM.DAT, and SYSTEM.DA0 when the Flash program is closed. Since the .dat files are in use, a run-time error will occur so only the .DA0 files are deleted.

Symantec Offers Free Online Fix for Destructive Worm.ExploreZip Worm
CUPERTINO, Calif. - June 14, 1999 - Symantec Corporation (Nasdaq: SYMC) today announced that a free tool to remove an active Worm.ExploreZip infection is available on its web site at http://www.sarc.com. The KILL_EZ.EXE tool removes infection from computers running on Windows 95, Windows 98 or Windows NT.
While protection has been available to Symantec Norton AntiVirus users via current virus definitions through LiveUpdate, the KILL_EZ.EXE tool does not require anti-virus software to run.
"Symantec AntiVirus Research Center (SARC) is offering this as a public service to administrators and other users," said Carey Nachenberg, chief researcher with SARC. "Administrators can use this tool to clean up infested networks and deploy via login scripts to rapidly cure the problem." While the tool removes Worm.ExploreZip, to have continued protection against malicious threats an anti-virus solution-such as Norton AntiVirus-is recommended.
The Worm.ExploreZip worm contains a malicious payload that can result in non-recoverable data and/or inoperable computer systems. The KILL_EZ.EXE tool performs the following tasks (upon verifying the system is infected by Worm.ExploreZip):
· Under Windows NT-removes changes made to the Windows Registry by the worm. Specifically, it deletes the registry value
EY_CURRENT_USER\Software\Microsoft\WindowsNTCurrentVersion\Windows\Run - Under Windows 95-removes changes made to the WIN.INI file, found in the Windows directory. Specifically, it will delete the line: run=c:\windows\system\explore.exe.
· KILL_EZ.EXE then completely removes the Worm.ExploreZip program from memory.
Finally, the tool deletes the EXPLORE.EXE file from the Windows system directory.
· Under Windows 95, or Windows 98, it will delete: C:\WINDOWS\SYSTEM\EXPLORE.EXE.
· Under Windows NT, it will delete c:\WINDOWS\SYSTEM32\EXPLORE.EXE.
Upon completion, KILL_EZ.EXE reports whether the system was infected with Worm.ExploreZip and, if infected, the system reports successful removal of the worm.
Worm.ExploreZip utilizes MAPI commands and Microsoft Outlook on Windows systems to propagate itself. The worm was first discovered in Israel and submitted to the Symantec AntiVirus Research Center (SARC) on June 6, 1999.
Norton AntiVirus users are advised to protect themselves from this worm by downloading the current virus definitions through LiveUpdate or from the Symantec web site at www.symantec.com/avcenter/download.html.
