| [slm] I think someone on the board has a virus. As far as I can tell they're using comcast from rockville maryland?? This is the virus they have cause I keep getting hit and a few other people on the board who keep their email public: Worm_SOBIG.F W32.Sobig.F@mm is a mass-mailing, network-aware worm that sends itself to all the email addresses it finds in the files that have the following extensions: .dbx .eml .hlp .htm .html .mht .wab .txt The worm uses its own SMTP engine to propagate and attempts to create a copy of itself on accessible network shares, but fails due to bugs in the code. Email routine details The email message has the following characteristics: From: Spoofed address (which means that the sender in the "From" field is most likely not the real sender). The worm may also use the address admin@internet.com as the sender. NOTES: The spoofed addresses and the Send To addresses are both taken from the files found on the computer. Also, the worm may use the settings of the infected computer's settings to check for an SMTP server to contact. The choice of the internet.com domain appears to be arbitrary and does not have any connection to the actual domain or its parent company.

Your details Body: See the attached file for details Please see the attached file for details. Attachment: your_document.pif document_all.pif thank_you.pif your_details.pif details.pif document_9446.pif application.pif wicked_scr.scr movie0045.pif NOTES: The worm de-activates on September 10, 2003. The last day on which the worm will spread is September 9, 2003. W32.Sobig.F@mm uses a technique known as "email spoofing," by which the worm randomly selects an address it finds on an infected computer. For more information on email spoofing, see the "Technical Details" section below. Also Known As: Sobig.F [F-Secure], W32/Sobig.f@MM [McAfee], WORM SOBIG.F [Trend], W32/Sobig-F [Sophos], Win32.Sobig.F [CA], I-Worm.Sobig.f [KAV] Type: Worm Infection Length: about 72,000 bytes Systems Affected: Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows XP Systems Not Affected: Linux, Macintosh, OS/2, UNIX, Windows 3.x Payload: Large scale e-mailing: Sends email to addresses collected from files with the following extensions: .wab, .dbx, .htm, .html, .eml, .txt. Releases confidential info: May steal system information, including passwords. Subject of email: Varies Name of attachment: Varies with .pif or .scr file extension Size of attachment: About 72,000 bytes Ports: UDP 123, 995, 996, 997, 998, 999, 8998 When W32.Sobig.F@mm is executed, it performs the following actions: Copies itself as %Windir%\winppr32.exe. NOTE: %Windir% is a variable. The worm locates the Windows installation folder (by default, this is C:\Windows or C:\Winnt) and copies itself to that location. Creates the file, %Windir%\winstt32.dat. Adds the value: "TrayX"="%Windir%\winppr32.exe /sinc" to the registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run so that the worm runs when you start Windows. Adds the value: "TrayX"="%Windir%\winppr32.exe /sinc" to the registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run so that the worm runs when you start Windows. Enumerates any network shares to which the infected computer has write access. The worm uses standard Windows APIs to do this. NOTE: Due to a bug in the code, the worm does not copy over network shares. Sobig.F can download arbitrary files to an infected computer and execute them. The author of the worm has used this functionality to steal confidential system information and to set up spam relay servers on infected computers. This functionality may also be used as a worm self-update feature. Under the correct conditions, Sobig.F attempts to contact one of the list of master servers, which the author of the worm controls. Then, the worm retrieves a URL that it uses to determine where to get the Trojan file, downloads the Trojan file to the local computer, and then executes it. In Sobig.F, the conditions for this download attempt are: According to UTC time, the day of the week must be Friday or Sunday. According to UTC time, the time of day must be between 7 P.M. and 10 P.M. Sobig.F obtains the UTC time through the NTP protocol, by contacting one of several possible servers on port 123/udp (the NTP port). The worm starts the download attempt by sending a probe to port 8998/udp of the master server. Then, the server replies with a URL, where the worm can download the file to execute. Sobig.F also opens the following ports: 995/udp 996/udp 997/udp 998/udp 999/udp And, it listens for any incoming UDP datagrams on these ports. Incoming datagrams are parsed, and upon receiving a datagram with the proper signature, the master server list of the worm may be updated. Network administrators should do the following: Block inbound traffic on ports 99x/udp. Block outbound traffic on port 8998/udp. Monitor NTP requests (port 123/udp), as these could be coming from infected computers. (The frequency of such checks for an infected computer should be once per hour.) Email spoofing W32.Sobig.F@mm uses a technique known as "spoofing," by which the worm randomly selects an address it finds on an infected computer. The worm uses this address as the "From" address when it performs its mass-mailing routine. Numerous cases have been reported in which users of uninfected computers received complaints that they sent an infected message to another individual. For example, Linda Anderson is using a computer infected with W32.Sobig.F@mm. Linda is neither using an antivirus program nor has the current virus definitions. When W32.Sobig.F@mm performs its email routine, it finds the email address of Harold Logan. The worm inserts Harold's email address into the "From" portion of an infected message, which it then sends to Janet Bishop. Then, Janet contacts Harold and complains that he sent her an infected message; however, when Harold scans his computer, Norton AntiVirus does not find anything, because his computer is not infected. Manual Removal As an alternative to using the removal tool, you can manually remove this threat. NOTE: If you are on a network or have a full-time connection to the Internet, disconnect the computer from the network and the Internet. Remove this threat from all the computers on the network before reconnecting to it. Disable or password-protect file sharing before reconnecting the computers to the network or to the Internet. For instructions, see your Windows documentation, or the document, "How to configure shared Windows folders for maximum network protection." IMPORTANT: Do not skip this step. Disconnect from the network before attempting to remove this worm. Disable System Restore (Windows Me/XP). Update the virus definitions. Do one of the following: Windows 95/98/Me: Restart the computer in Safe mode. Windows NT/2000/XP: End the Trojan process. Run a full system scan and delete all the files detected as W32.Sobig.F@mm. Delete the value that was added to the registry. For specific details on each of these steps, read the following instructions. 1. Disabling System Restore (Windows Me/XP) If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer. Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations. Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat. For instructions on how to turn off System Restore, read your Windows documentation, or one of the following articles: "How to disable or enable Windows Me System Restore" "How to turn off or turn on Windows XP System Restore" 2. Updating the virus definitions Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. There are two ways to obtain the most recent virus definitions: Running LiveUpdate, which is the easiest way to obtain virus definitions: These virus definitions are posted to the LiveUpdate servers once each week (usually on Wednesdays), unless there is a major virus outbreak. To determine whether definitions for this threat are available by LiveUpdate, refer to the Virus Definitions (LiveUpdate). Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted on U.S. business days (Monday through Friday). You should download the definitions from the Symantec Security Response Web site and manually install them. To determine whether definitions for this threat are available by the Intelligent Updater, refer to the Virus Definitions (Intelligent Updater). The Intelligent Updater virus definitions are available: Read "How to update virus definition files using the Intelligent Updater" for detailed instructions. 3. Restarting the computer in Safe mode or ending the Trojan process Windows 95/98/Me Restart the computer in Safe mode. All the Windows 32-bit operating systems, except for Windows NT, can be restarted in Safe mode. For instructions, read the document, "How to start the computer in Safe Mode." Windows NT/2000/XP To end the Trojan process: Press Ctrl+Alt+Delete once. Click Task Manager. Click the Processes tab. Double-click the Image Name column header to alphabetically sort the processes. Scroll through the list and look for Winppr32.exe. If you find the file, click it, and then click End Process. Exit the Task Manager. 4. Scanning for and deleting the infected files Start your Symantec antivirus program and make sure that it is configured to scan all the files. For Norton AntiVirus consumer products: Read the document, "How to configure Norton AntiVirus to scan all files." For Symantec AntiVirus Enterprise products: Read the document, "How to verify that a Symantec Corporate antivirus product is set to scan all files." Run a full system scan. If any files are detected as infected with W32.Sobig.F@mm, click Delete. 5. Deleting the value from the registry CAUTION: We strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified keys only. Read the document, "How to make a backup of the Windows registry," for instructions. Click Start, and then click Run. (The Run dialog box appears.) Type regedit Then click OK. (The Registry Editor opens.) Navigate to the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run In the right pane, delete the value: "TrayX"="%Windir%\winppr32.exe /sinc" Navigate to the key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run In the right pane, delete the value: "TrayX"="%Windir%\winppr32.exe /sinc" Exit the Registry Editor.

| [wlm] If you have those emails in your inbox it doesn't mean you have the virus!!! It just means that someone who has the virus somehow has your email address either in their files, their internet cache, or in their addressbook. If you use web based email like Yahoo or Hotmail you cannot spread this virus and you cannot be infected with it. It only happens to people who have Outlook and other mail programs like that on their actual computer or to actual mail servers. But as a general rule, I never open attachments from those type of titles or files with .exe or .pif etc!!! I'd have to know exactly what it is and the email would have to describe what file is being attached. Also, if you're using Yahoo make sure to turn your Bulk folder Spamguard on.. it just dumps all those bulk email virus emails in there and you can just clear that out every now and then... |
