W64.Shruggle.1318
Discovered on: August 20, 2004
Last Updated on: August 24, 2004 09:06:24 AM

W64.Shruggle.1318 is a direct-action file infector, similar to W64.Rugrat.3344, which infects AMD64 Windows Portable Executable (PE) files. It is a fairly simple proof-of-concept virus; however, it is the first known virus to attack 64-bit Windows executables on AMD64 systems.

The virus is written in AMD64 assembly code.

Type: Virus
Infection Length: 1318 bytes

Systems Affected: Windows 64-bit (AMD64)
Systems Not Affected: DOS, Linux, Macintosh, OS/2, UNIX, Windows 2000, Windows 3.x, Windows 64-bit (IA64), Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows XP

Technical Details:

When W64.Shruggle.1318 is executed, it searches 64-bit executable files that are in same folder, and all subfolders, as the one from which the virus was executed. When it finds a 64-bit executable file, the virus appends itself to the file, including .dll files.

Note: The virus does not infect 32-bit Portable Executable files, and it will not run natively on 32-bit Windows platforms. However, it can be run on a 32-bit computer that is using 64-bit simulation software.


Removal Instructions:

The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.


Update the virus definitions.
Run a full system scan, and delete all of the files that are detected as W64.Shruggle.1318.

Additional information:

The virus uses a small number of Win64 APIs from the following three libraries:

Ntdll.dll
Sfc_os.dll
Kernel32.dll

From Ntdll.dll, the virus uses the following functions:
LdrGetDllHandle()
RtlAddVectoredExceptionHandler()
RtlRemoveVectoredExceptionHandler()

The virus supports vectored exception handling to avoid crashing during infections.

The SfcIsFileProtected() function of Sfc_os.dll is used to avoid infecting executables that are protected by the System File Checker (SFC).

The following sixteen functions are used from Kernel32.dll to implement a standard file infection of a AMD64 Portable Executable image:
CreateFileMappingA()
CreateFileW()
CloseHandle()
FindFirstFileW()
FindNextFileW
FindClose()
GetFullPathNameW()
GetTickCount()
GlobalAlloc()
GlobalFree()
LoadLibraryA()
MapViewOfFile()
SetCurrentDirectoryW()
SetFileAttributesW()
SetFileTime()
UnmapViewOfFile()

The virus carries the following string, which is never displayed, within itself:

Shrug - roy g biv

The file infection routine is standard. The last section of the executable is marked as executable, the virus body is inserted into the last section, and a random number of bytes are appended to the end of the virus body.

The virus author is also the author of a number of other proof-of-concept viruses. These are collected under the name [url="http://securityresponse.symantec.com/avcenter/venc/data/w32.chiton.gen.html"]W32.Chiton.gen[/url].

Trojan.Mitglieder.O is a Trojan horse that allows an infected computer to be used as an email relay.

Type: Trojan Horse

Systems Affected: Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows XP
Systems Not Affected: Linux, Macintosh OS X, Novell Netware, OS/2, UNIX

When Trojan.Mitglieder.O runs, it does the following:


Copies itself as the following files:

%System%\foõ.exe
%System%\norat.exe
%System%\winerdir.exe.

Note: %System% is a variable. The Trojan locates the System folder and copies itself to that location. By default, this is C:\Windows\System (Windows 95/98/Me), C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).


Adds a value:

"ssgrate.exe"="%System%\winerdir.exe"

to the registry key:

HKEY_CURRENT_USER\Software\Microsoft\WindowsCurrentVersion\Run

so that the worm runs when you restart Windows.


Adds the values:

"port" = "0x000097e3"
"uid" = "[random number]"
"wdrn" = "0x00000001"

to the registry key:

HKEY_CURRENT_USER\Software\DateTime8


Attempts to injects itself as a thread into the Explorer.exe process.


Opens and listens on TCP port 28883.

Note: This functionality is usually employed to send unsolicited commercial email.

Systems Not Affected: DOS, Linux, Macintosh, OS/2, UNIX, Windows 3.x, Windows 95, Windows 98, Windows CE, Windows Me, Windows NT, Windows Server 2003

Technical Details:

When W32.Sasser.G runs, it does the following:


Attempts to create mutexes named "PinaasoSky" and "Jobaka3", exiting if it fails. This ensures that no more than one instance of the worm can run on a computer at any time.


Copies itself as one of the following files:

%Windir%\avserve3.exe.
%Windir%\wserver.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.


Drops and executes the following files:

%Windir%\skynet.cpl
%Windir%\comp.cpl

Note: These files are detected as W32.Netsky.AC@mm.


Adds one of the following values:

"avserve3.exe"="%Windir%\avserv3.exe"
"wserver"="%Windir%\wserver.exe"

to the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

so that the worm runs when you start Windows.


Prevents any attempts to shut down or restart the computer.


Starts an FTP server on TCP port 5554. This server is used to spread the worm to other hosts.


Retrieves the IP addresses of the infected computer.


Generates a second IP address, based on one of the IP addresses retrieved from the infected computer.


Connects to the generated IP address on TCP port 445 to determine whether a remote computer is online.


If a connection is made to a remote computer, the worm will send shell code to it, which may cause it to open a remote shell on TCP port 9996.


Uses the shell on the remote computer to reconnect to the infected computer's FTP server and retrieve a copy of the worm. This copy will have a name consisting of four or five numbers, followed by _up.exe. For example, 74354_up.exe.


Creates a file at C:\win2.log that contains the IP address of the computer that the worm most recently attempted to infect, as well as the number of infected computers.

Note: The Lsass.exe process will crash after the worm exploits the Windows LSASS vulnerability. Windows will display the alert and shut down the system in one minute.

Removal Instructions:

Before you begin:
If you are running Windows 2000 or XP, and have not yet done so, you must patch for the vulnerability described in Microsoft Security Bulletin MS04-011. If you do not, it is likely that your computer will continue to be reinfected.

Injects a process-watching procedure as a thread into either Explorer.exe or Taskmgr.exe. This thread will attempt to launch %System%\Iexplore.exe if it detects that the worm's process has stopped.


The worm will then listen on TCP port 6060. The backdoor procedures steal information of an infected computer and stores it in the file, C:\Netlog.txt. The worm then emails the stolen information to the hacker.


Extracts the location of the KaZaA-shared folder from the registry. Then, it copies itself to the folder as one of the following:

BlackIcePCPSetup_creak
HEROSOFT
Passware5.3
REALONE
W32Dasm

Backdoor.Akak
Discovered on: September 02, 2004
Last Updated on: September 03, 2004 11:16:52 AM

Backdoor.Akak is a backdoor server that also creates a SOCKS proxy on the compromised system. Reports indicate that Web sites exploiting the Microsoft Internet Explorer Drag And Drop File Installation Vulnerability may install it.

Also Known As: Backdoor.Win32.BoomRaster.a (KAV)

Type: Trojan Horse
Infection Length: 8704 bytes

Systems Affected: Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows XP

Backdoor.Akak is a backdoor server program that may be installed when you visit a malicious Web site using Internet Explorer. These pages may contain code that exploits the Microsoft Internet Explorer Drag And Drop File Installation Vulnerability.

If Backdoor.Akak runs, it will download the file, Testexe.exe or Rb.exe, to the Windows Startup folder.

Following this, when you start Windows, it does the following:


Executes the downloaded file.


Creates the mutex "J&^srl!hsl^AHSgh" so that only one instance of the backdoor is present in memory.


Registers itself as a service so that it continues to run even if you log off.


Copies itself as %System%\rb.exe.

Note: %System% is a variable that refers to the System folder. By default, this is C:\Windows\System (Windows 95/98/Me), C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).


Creates the value:

"RamBooster2"="%System%\rb.exe "

in the registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

so that the Trojan runs every time that Windows starts.


Issues the command "net stop SharedAccess" to disable the Windows Internet Connection Firewall (ICF), if it is running on the system. (Windows 2000/XP).


Contacts a master server located at 202.104.242.156 on TCP port 4321 and downloads information, which is stored in the file, %System%\lhosts.txt.


If the backdoor cannot create the lhosts.txt file, it will instead store this information in the file, Kaka2.txt, which it creates in the current working folder.


Creates a SOCKS proxy on TCP port 5555. This allows the compromised computer to be used to proxy protocols such as HTTP.


Listens on TCP port 4321 for commands from the remote attacker. The attacker can do any of the following:
Obtain system information
Download and execute files on the compromised computer
Uninstall the back door
Update the address of the master server

Removal Instructions:

Disable System Restore (Windows Me/XP).
Update the virus definitions.
Run a full system scan and delete all the files detected as Backdoor.Akak.
Delete the value that was added to the registry.
Re-enable the SharedAccess service (Windows 2000/XP only).

Also Known As: W32/Mydoom.t@MM [McAfee], WORM_MYDOOM.T [Trend], MyDoom.T [F-Secure]
Variants: W32.Mydoom.P@mm
Type: Worm
Infection Length: 37,888 bytes, 8,192 bytes

Systems Affected: Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows XP
Systems Not Affected: DOS, Linux, Macintosh, Novell Netware, OS/2, UNIX

Technical Details:

When W32.Mydoom.R@mm is executed, it does the following:


Copies itself as %System%\tasker.exe.

Notes:
%System% is a variable that refers to the System folder. By default this is C:\Windows\System (Windows 95/98/Me), C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).


Creates the file %System%\Nemog.dll(8,192 bytes), which is a component of W32.Mydoom.R@mm.


Creates the file, %Temp%\Message, and then opens it with Notepad.


Note: %Temp% is a variable that refers to the Windows temporary folder. By default, this is C:\Windows\TEMP (Windows 95/98/Me/XP) or C:\WINNT\Temp (Windows NT/2000).


Creates a mutex, "EnD-Of-SkyNet", which allows only one instance of the worm to run in memory.


Adds the value:

"Task"="%System%\tasker.exe"

to the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

so that the worm starts when Windows starts.


Adds the value:

"(Default)"="%System%\Nemog.dll"

to the registry key:

HKEY_CLASSES_ROOT\CLSID\{E6FB5E20-DE35-11CF-9C87-00AA005127ED}\InprocServer32


Creates the following registry keys:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\Version
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\Version


May also attempt to open a back door on port 5422 and allow a remote attacker to have unauthorized access to the infected system. This would allow a remote attacker to download and execute remote files.

A virus has been identified by Sophos anti-virus experts which attempts to talk to end users over their speakers. The worm, known as W32/Amus-A, spreads via e-mail using subject lines such as "Listen and Smile". If users launch the attached file the worm will attempt to spread, and also tries to use the Microsoft Speech engine to read out a greeting as follows:

"hamsi. I am seeing you. Haaaaaaaa. You must come to turkiye. I am cleaning your computer. 5. 4. 3. 2. 1. 0. Gule. Gule."

As well as this the worm changes the users Internet Explorer settings so users see a message in Turkish rather than their usual start page. Graham Cluley, senior technology consultant for Sophos, said the following about the worm:

"It's depressing to see virus writers are active in Turkey. It seems whoever created this worm has complaints about the quality of internet service in his country, but this isn't the proper way to register his opinion. Hopefully if any internet users receive an Amus-infected email they will treat it with suspicion and not launch the attachment."

The worm is not particuarly widespread, nor is it particuarly damaging in its present form. However, users are recommend as always to keep their anti-virus definitions up to date to prevent worms like this from propagating, and to be careful when opening attachments, even if they appear to be from a trusted source.

[b]New MyDoom draws on IE flaw to spread[/b]
[i]A new version of MyDoom uses an unpatched flaw in Microsoft's Internet Explorer to spread, antivirus companies warned on Monday.[/i]

[size=1]By Robert Lemos[/size]

The recently discovered vulnerability in the browser software allows the offshoot to infect a PC after a user clicks on a link, according to advisories from security software makers Symantec and McAfee. The program sneaks past antivirus applications that detect malicious software by scanning e-mail messages with attached programs.

The companies said they had only detected a few instances of the infector, which is labelled MyDoom.AG by McAfee and MyDoom.AH by Symantec.

"We have only received one submission from the field, but the technical aspects of this are concerning," said Craig Schmugar, senior virus research manager at McAfee. "It has all the components there to become a significant virus."

It's not the first time a code writer has exploited a flaw in a Microsoft product before the software giant has had a chance to plug the hole. An aggressive advertiser attempted to [url="http://news.com.com/Pop-up+toolbar+spreads+via+IE+flaws/2100-1002_3-5229707.html?tag=nl"]surreptitiously install[/url] a pop-up toolbar in victim's Web browsers using two previously unpatched security flaws in Internet Explorer.

Microsoft said that it was investigating the flaw and was aware of a new virus exploiting the issue.

"As a best practice, users should always exercise extreme caution when opening unsolicited attachments from both known and unknown sources," said Microsoft in a statement sent to CNET News.com. "In addition, we continue to encourage customers follow our 'Protect Your PC' guidance of enabling a firewall, getting software updates and installing antivirus software."

The latest MyDoom virus appears as an e-mail in an inbox. The body of the message states: "Look at my homepage with my last webcam photos!" or "FREE ADULT VIDEO! SIGN UP NOW!" Both messages have text that links them to a Web page generated by the virus and hosted on the infected computer that sent the e-mail.

When the victim clicks on the link, a Windows-based PC will call Internet Explorer and load a malicious Web page from the previously infected computer. The page contains the [url="http://news.com.com/Exploit+code+makes+IE+flaw+more+dangerous/2100-1002_3-5439370.html?tag=nl"]IFrame vulnerability recently publicized[/url] on security mailing lists. The virus uses the flaw to execute code on the victim's computer, infecting the system. The virus harvests e-mail addresses on the compromised system, sends out mail to spread the virus further, sets up a Web server and attempts to contact several Internet relay chat (IRC) servers as a way to notify the virus's creator of that a new system has been compromised.

The fact that the virus creates a Web server and uses that server to infect other systems is a significant departure from previous versions of MyDoom, and other viruses in general, Schmugar said.

"There was a decent amount of work that went into this," he said. "There was a good bit of attention (among security researchers) to the demo code (of this flaw). Someone grabbed the demo code and tweaked it quite a bit."

McAfee rates the program a low threat, but Schmugar said he thinks it might spread widely.

MyDoom worm is back
By JACK KAPICA
Globe and Mail Update



In a development certain to trouble computer security experts, only four days passed between the discovery of a vulnerability in the Internet Explorer browser and the appearance of a worm designed to exploit it.

The virus — in this case, technically a worm — is a variant of the well-known mass-mailing MyDoom infection, with the difference that rather than delivering an attachment, the e-mail just asks recipients to click on a link. The browser is then directed to the infected destination site, where the worm, dubbed Mydoom.ah by McAfee Inc.,

installs itself on the victim's computer.

The worm targets a Microsoft Internet Explorer IFRAME buffer overflow vulnerability, which was discovered and made public by two hackers with aliases "ned" and "SkyLined" on Friday. Only four days later a worm exploiting the weakness was developed and set loose, virus-tracking companies said reported.

The period of time between discovery of a flaw and the appearance of an infection has been shortening recently. Last year, the time difference was, on average, 28 days.

McAfee's Anti-virus and Vulnerability Emergency Response Team (AVERT) raised the risk assessment of MyDoom.ah to medium after receiving close to 100 reports of the virus being stopped or infecting users from the field, from both the virus itself as well as customer submissions. Most of these reports have arrived from the United States.

The new variant is a mass-mailing worm that sends messages with a hyperlink directing people to an infected machine. Following the hyperlink results in an infection occurring on vulnerable Microsoft Internet Explorer Web browsers.

The worm contains its own SMTP engine to construct outgoing messages. It harvests addresses from local files and then uses those addresses in the "From" field to send itself, producing a message with a spoofed return address.

Users should be wary, McAfee warned, and should delete any e-mail with the subject:

"hi!", "hey!", "Confirmation" or just blank. The message body will be one of the following:

"Congratulations! PayPal has successfully charged $175 to your credit card."

"Your order tracking number is A866DEC0, and your item will be shipped within three business days."

"To see details please click this link."

Another variation pretends to be an invitation to a sex site. The text of the message says: "Hi! I am looking for new friends. My name is Jane, I am from Miami, FL. See my homepage with my weblog and last webcam photos! See you!"

McAfee and Symantec, two makers of popular antivirus products, have updated their virus definition files to include MyDoom.ah for subscribers.

Microsoft Corp., which makes the Internet Explorer browser, is expected to issue its monthly batch of security patches later on Tuesday, but it was not immediately clear whether it would include a patch for the new worm.

The company did say that users of Windows XP who had installed Service Pack 2 were at a "reduced risk."

New Bropia worm rated "code orange"



SEOUL, Feb. 3 — Korean security specialists at Globeal Hauri are warning of a new variant of the recently discovered Bropia worm, which is more dangerous than its predecessor.

Symptoms include a file, seemingly sent from a "buddy," which is loaded with the virus and infects the PC as soon as it opened. Remote access hijacks the infected PC. Volume differences and right mouse click might indicate the PC user that something is wrong.

Once Bropia infects a system, it resides in the memory and continues spreading through MSN Messenger. Bropia is a member of the Rbot family of worms affecting the Windows platform, which installs a back door on the system and gives an attacker a way of accessing and controlling the infected system remotely. That would allow unauthorized remote access to the infected computer via specific IRC channels while running in the background as a service process.

Another interesting component is that the new Bropia is loaded with a Bot virus component that opens the 1294 port.

The new Bropia copies itself into the system folders and creates one of the following file names: LOL.scr, Webcam.pif, bedroom-thongs.pif, naked_drunk.pif, LMAO.pif, ROFL.pif, underware.pif, Hot.pif or webcam.pif

The infected system folder can vary, depending on each user's configuration, with the most common being C:\Windows\System (Windows 95/98/Me); C:\Winnt\System32 (Windows NT/2000) and C:\Windows\System32 (Windows XP).

The worm can be temporarily disabled bly blocking the 1294 port with any firewall. This is not a "spreading" port but the PC might receive an attack order from this port.

Is this the same thing that Mess.Be has reported which is spreading through MSN Messenger?

Trend Micro Inc has released an overview of a worm that is currently doing the rounds infecting users PC's and transferring itself through the MSN Messenger service.

MSN Messenger is under attack of a worm that comes with a seductive name and download link. The user clicks on the link and gets the copy of attached worm for his PC. The worm can spread on the network and shared computers. The worm can disable the Anti-Virus software and then infect the Files in PC, It can also spread easily after it disables anti virus program.

Trend Micro Inc. has also raised the threat level on the W32/Bropia worm. The company said that worm could cause more harm in case it spread more through MSN Messenger buddies and Shared Networks. The virus has antidebugging feature also.

The virus logs keystrokes. It can also retrieve credit card numbers and other sensitive information. The W32/Bropia worm contains a variant of the Rbot backdoor Trojan. The virus could be a higher threat to sensitive information as it can store information. It is also capable of using the infected machine to hijack sensitive data.

[b][color="darkred"]-------------------------------------------------------[/b][/color]

As of February 2, 2005, 6:55 PM (Pacific Standard Time/GMT -8:00), TrendLabs has declared a Medium-Risk alert to control the spread of this new WORM_BROPIA variant that is spreading in Korea, China, Taiwan, and the United States.

This memory-resident worm propagates itself via MSN Messenger by sending a copy of itself using different file names to all available or online contacts. Thus, users of the said messaging program should not accept or open these files to avoid infection.

System administrators can also block MSN Messenger transfers to control the spread of this worm.

As a general rule, MSN Messenger users should avoid accepting file transfers coming from an untrusted source.

This worm also drops and executes the file SEXY.JPG in the root folder. This normal .JPG file displays the following [url="http://www.trendmicro.com/vinfo/images/WORM_BROPIA_F.gif"]image.[/url]
It also attempts to drop and execute a bot program, which Trend Micro detects as WORM_AGOBOT.AJC.

Unlike its previous variants, this worm also has an anti-debugging technique. That is, this worm will not run if any of the following debugging applications are currently running on the affected system:
* NT-ice
* Softice
It is also capable of setting the affected system's volume levels to zero, which may be used to prevent users from hearing any sound prompts, especially those that may be coming from antivirus and security applications.

Zafi-D a 'High-Alert' Top Threat
March 4, 2005
The Zafi-D worm has not only received 'high alert' threat status, it's become the most widespread malware roaming the Internet.

The worm, which spreads via email attachments and peer-to-peer accounts, received 'high alert' threat status from Sophos, Inc., an anti-virus and anti-spam company with U.S. headquarters in Lynnfield, Mass. Sophos analysts report that the worm harvests email addresses off infected computers and emails copies of itself out to them, and it also installs itself on the computer's registry. When it copies itself to the Windows system folder with the filename Norton Update.exe.

Sophos reports that Zafi-D makes up 30.8 percent of all malware traffic in the wild.

''It looks like the Zafi-D worm is going to be hanging around like a bored teenager for some time to come, unless more home users realise how important it is to update their anti-virus software,'' says Carol Theriault, a security consultant at Sophos. ''This Hungarian worm accounts for almost one in three viruses reported.''

Zafi-D is reported to display a fake error message box with the caption ''CRC: 04F6Bh'' and the text ''Error in packed file!''.

Worm.Win32.Sober.L Alert! A new variant of the Sober worm is spreading fast. As it's predecessors, Sober.L spreads as an email attachment in emails which are sent to all email addresses found on the victim's harddisk. Even if the executable file is packed in a .ZIP file, many users open the file and activate the worm this way. For novice users it's hard to see that it is a worm generated email because the email subject is "your password + accountnumber !". The email body text is the following: hi, i've got an admin mail with a Password and Account info! but the mail recipient are you! it's probably an esmtp error, i think. i've copied the full mail text in the Windows text-editor & zipped. ok, cya... The recipient is advised to open the attached file "Acc_text.zip". The worm also spreads in a German version, which is used on all German email addresses. The German subject is "ich habe ihre e-mail bekommen !". The email body text is: Hallo, jemand schickt ihre privaten Mails auf meinem Account. Ich schaetze mal, das es ein Fehler vom Provider ist. Insgesamt waren es jetzt schon 6 Mails! Ich habe alle Mail-Texte im Texteditor kopiert und gezippt. Wenn es doch kein Fehler vom Provider ist, sorge dafuer das diese Dinger nicht mehr auf meinem Account landen, es Nervt naemlich. Gruss If you start the worm, you will see this window: [attachment=625:attachment] [url="http://www.emsisoft.com/en/malware/?Worm.Win32.Sober.L"]Source & More Information[/url]

W32.Kelvir.DA is a worm that spreads a variant of W32.Randex through MSN Messenger.

Type: Worm
Infection Length: 6,442 bytes

Systems Affected: Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows XP

When W32.Kelvir.DA is executed, it performs the following actions:

1. Sends the following message with a link to all the MSN Messenger contacts on the compromised computer:

its you in this cartoon!!
[http://]cartoonics.nl/[REMOVED]/cartoon.php?email=[RANDOM EMAIL ADDRESS]

Note: It has been reported that [RANDOM EMAIL ADDRESS] may be called nav_rro@hotmail.com.

2. Drops a variant of W32.Randex on the compromised computer if a recipient clicks on the link and downloads the file [RANDOM EMAIL ADDRESS].

Another recent worm puts the word "fucker" in the mouths of the infected, sends out the message: "you are on this picture and you never told me" and links to a would-be Pearl Jam fansite. The badly spelled "groupicture.php" in the URL gives it away, really. That, and the fact that I have not heard about Pearl Jam for 7 years, let alone be on a picture with them.

Other variations claim you're a staff member at a company/hotel/restaurant/whatever called Millenium ("i didnt know you worked here????"), you have a profile page at the wrongly spelled vbulettin site or that you are starring in a packet of beach pictures. For one last time (figuratively, I'm afraid): pictures and zipfiles do NOT have a .PIF extension... nothing worthwile does, actually. And secondly, never ever click links that end with your MSN Messenger account address.

Top Threat:Mitglieder.DQ
Executive Summary
Name: Mitglieder.DQ (Panda)
Affects: Windows 2003/XP/2000/NT/ME/98/95
Size: 36,864 bytes

What it does: Mitglieder.DQ is a Trojan horse program with no direct mechanism for spreading. It is placed on web sites and other media from which users are tricked into downloading and executing it.

It contains a large number of process names belonging to security software and the software that keeps it up to date and it attempts to stop these processes. It then attempts to download the file OSA3.GIF from a large list of web sites. The .GIF extension is meant to trick users and security software; the file is actually an executable.

The program also copies two files, WINSHOST.EXE and WIWSHOST.EXE, to the Windows System directory. The first is a copy of the Trojan, the second a DLL used by it. It also overwrites the Windows HOSTS file with the following text:

127.0.0.1 localhost

It also creates registry values for itself in the HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER Run keys in order to run itself at boot time. It creates one more value:

HKEY_CURRENT_USER\ Software\ FirstRun
FirstRunRR = 0x00000001

as an infection mark, in order to check if it has already affected the computer.

How to avoid it: Install antivirus software and keep it up to date. Only run executables from highly-trusted sources.

How to remove it: Delete the following registry keys from the system:

* HKEY_LOCAL_MACHINE\ Software\ Microsoft\ Windows\ CurrentVersion\ Run
winshost.exe = %sysdir%\winshost.exe
* HKEY_CURRENT_USER\ Software\ Microsoft\ Windows\ CurrentVersion\ Run
winshost.exe = %sysdir%\winshost.exe
* HKEY_CURRENT_USER\ Software\ FirstRun
FirstRunRR = 0x00000001

(%sysdir% is the Windows system directory)

Then restart the computer. Afterwards delete %sysdir%\winshost.exe and %sysdir%\wiwshost.exe.

It's best also to scan your system with an up-to-date anti-virus scanner at this point.
