OMG! This is so real looking!



It looks SO freaking real!

I almost thought it was real, till I thought...how the hell does MS have my email.

I'm sure that a LOT of non-computer savvy people fell for this trick.

Anyone have an ID on the file?

Good catch! I'll warn my PC friends. Although I don't get updates from MS, that looks real to me. E-mailed updates should seem weird, so most people should catch it.

Nasty worm poses as MS security update
By John Leyden
Posted: 19/09/2003 at 08:03 GMT

Windows users were yesterday warned of the appearance of a worm that poses as a security update from Microsoft but actually causes all manner of mischief on infected PCs.

Swen-A (AKA Gibe-F) is a mass-mailing worm that also attempts to spread through file-sharing networks, such as KaZaA and IRC, and over local area network shares. The worm attempts to de-activate antivirus and personal firewall programs running on an infected computer.

AV vendors warn that the worm is spreading rapidly and that disinfection is difficult. As usual this is a Windows-only menace - Linux, Macintosh, OS/2 and Unix users are immune.

Swen-A uses a well known vulnerability in Internet Explorer to execute directly from e-mail. Windows users can also catch the pox by executing an infected email attachment.

Finnish AV firm F-Secure compares the worm to Gibe, and believes it is likely that the same author wrote both worms.

Swen-A (like Gibe and numerous other viruses before it) purports to be a security alert from Microsoft. This time around infectious messages come with a well-presented HTML message complete with graphics that are more likely to trip up the unwary.

The worm can also impersonate mail delivery failure notices, attaching itself as a randomly named executable.

Swen-A attempts to spread by emailing itself using its own SMTP client to addresses extracted from various sources on the victim's drives (e.g. MBX and DBX files). Periodically the worm presents users with a fake MAPI Exception error, prompting them to enter the details of their email account (name, user name, servers).

Sneaky.

Swen-A also makes modifications which make it hard to run Reg Edit, along with other changes to infected PCs explained in advisories from F-Secure and Symantec.

Windows users are advised to update the virus signature files on their AV scanners to defend themselves against the worm, which is all very well but the reason the virus got a hold in the first place is probably because of the shortcomings of the scanner model.

Like Microsoft has repeatedly said though they don't email patches, so hopefully not too many people will be fooled.

I agree with torgone. I would of noticed the punctuation error's before anything else. Not to mention the fact that microsoft would never have an attatchment, probably just a link to the page to d/l off of. Bleh, though I guess alot of people would fall for that.

I got that e-mail but avg had stopped the attachment.... I knew it wasn't from ms because they never send any attachments and it doesn't look like the normal emails i get from MS, and yes I do get regular e-mails from them..... And it had a return address that was not @microsoft.com..... i forget what it was because i deleted that email this morning.....

Didn't you know - they have everyone's e-mail, and I'm sure they are working hard and how to make you pay them for using your e-mail address. Anyway I've got to say this new worm is very crafty and I'm sure that lots of people who are not punctuation freaks would have been caught out.

We got the warning at work today about this. Evidently our mail servers will block it, but they wanted us to be warned for our PCs at home.

This isn't the first email I've seen something like this. I received a couple of emails that had a link in them that sent you to a website that was supposed to update Windows. The link was to a site that had microsoft in the address. This is not exact, but it was something like microsoft.upate.com, which sends you to upate.com instead of microsoft.com. It might fool someone who wasn't looking to closely at the address.

I got 6 of them today. Let me tell you, this Mac user felt pretty special getting that much email directly from Microsoft!

There's an email address in the "Return-Path" header. If this one is anything like Klez, that's who it really came from.

Not so great lurker
 
Location: NY
When I first read about this virus, and saw a screenshot, the first thing that made me suspicious that it was fake is that MS always links you to the knowledgebase article that explains what vulnarabilities it is patching. Basically since it doesn't give you the MS Q article number (or even a link to what it is suppossed to be), most people who are familiar with these types of notices would think it rather odd, BUT it is close enough that the average user would prob run it anyways.

yeah I dont' get emailed my Microsoft, just a snail mail every so often. How do they address me? None other than my firstname followed by its nickname of course (cough*morons*cough)

"Dear Joseph Joe" ... ugh, that gets to me. Aside from the fact that they NEVER sent me my MCP card.

Right Now
 
Location: Home
Sometimes purporting to be a Microsoft Security Update, this worm is intended to propagate via various mechanisms:

mailing itself to recipients extracted from the victim machine
copying itself over network shares (mapped drives)
sharing itself over the KaZaa P2P network
sending itself via IRC
The worm is written in MSVC. Though in a different HLL, it bears similarities to W32/Gibe.b@MM (original Gibe variants were written in VB).

The worm terminates processes relevant to various security and anti-virus products (see below).

Proactive Detection : This worm is detected as "virus or variant New Worm" with the 4120 DATs or greater (with program heuristics enabled).

Mail Propagation

The virus contains its own SMTP engine to construct outgoing messages.

Various outgoing messages are created. Some make use of an IE exploit to ensure the worm attachment is run upon viewing the email. See Microsoft Security Bulletin (MS01-020) . One such message bears the following characteristics:

Subject : Returned Response
From : Email Delivery Service (kmailengine@yahoo.com)
Body : Undeliverable mail to (email address )

Messages constructed to take advantage of this vulnerability will be detected as Exploit-MIME.gen.exe with the 4215 DATs or greater (and earlier as Exploit-MIME.gen).

Multiple subject lines and attachment names are constructed from pools of strings within the worm to be used in outgoing messages. Target email addresses are extracted from files on the victim machine.

At least one message masquerades as a Microsoft update:



Share Propagation

The worm copies itself to the startup folder on mapped network drives. A random filename is used.

The following network locations are targetted:

windows\all users\start menu\programs\startup
windows\start menu\programs\startup
winme\all users\start menu\programs\startup
winme\start menu\programs\startup
win95\all users\start menu\programs\startup
win95\start menu\programs\startup
win98\all users\start menu\programs\startup
win98\start menu\programs\startup
document and settings\all users\start menu\programs\startup
document and settings\default user\start menu\programs\startup
document and settings\administrator\start menu\programs\startup
winnt\profiles\all users\start menu\programs\startup
winnt\profiles\default user\start menu\programs\startup
winnt\profiles\administrator\start menu\programs\startup
IRC Propagation

The worm drops a SCRIPT.INI file (123 bytes) into the mIRC program folder in an attempt to propagate via IRC (using dcc send). This file is proactively detected as MIRC/Generic with the 4149 DATs or greater.

P2P Propagation

The worm makes copies of itself in a directory (random name) within the system temp directory. Enticing filenames are used, for example:

SIRCAM CLEANER.EXE
YAHOO HACKER.EXE
HALLUCINOGENIC SCREENSAVER.EXE
etc etc
The following Registry key is modified to share these copies via the KaZaa P2P network:

HKEY_CURRENT_USER\Software\Kazaa\LocalContent
"Dir99" = 012345:C:\WINDOWS\TEMP\(random directory name)

Propagation via Newsgroups

Within the list of servers carried in the worm are multiple NNTP servers. Analysis is currently ongoing to determine exactly how these are used (email address harvesting and/or replication).

Symptoms
Display of the above dialog boxes
Unexpected termination of AV/security product
Inability to run RegEdit on the victim machine

Top of Page

Method Of Infection
Installation

When run on the victim machine, a sequence of fake message boxes are displayed:







The worm installs itself (using a random filename) into %WinDir%, for example:

C:\WINDOWS\ZNFUL.EXE

A Registry key is added to hook system startup, for example (random string and filename will obviously change):

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\
CurrentVersion\Run "(random string)" = ZNFUL.EXE autorun

Various Registry keys are modified to hook the execution of the following file types:

BAT
COM
EXE
PIF
REG
SCR
For this, the following Registry keys are set:

HKEY_CLASSES_ROOT\batfile\shell\open\command
"(Default)" = %filename% "%1" %*

HKEY_CLASSES_ROOT\comfile\shell\open\command
"(Default)" = %filename% "%1" %*

HKEY_CLASSES_ROOT\exefile\shell\open\command
"(Default)" = %filename% "%1" %*

HKEY_CLASSES_ROOT\piffile\shell\open\command
"(Default)" = %filename% "%1" %*

HKEY_CLASSES_ROOT\regfile\shell\open\command
"(Default)" = %filename% showerror

HKEY_CLASSES_ROOT\scrfile\shell\config\command
"(Default)" = %filename% "%1"

HKEY_CLASSES_ROOT\scrfile\shell\open\command
"(Default)" = %filename% "%1" /S

(Where %filename% is the random filename which the worms installs into %WinDir% as.)

The following files are also dropped:

%WinDir%\GERMS0.DBV - email addresses harvested from the victim machine are written to this file (: delimitted)
%WinDir%\SWEN1.DAT - list of remote servers
Other randomly named files may also be dropped in %WinDir% - a batch script (approx 50 bytes) for launching the dropped copy of the worm, and a config file (approx 100-150 bytes) containing path/filename data.

The following Registry key is set in order to prevent RegEdit being used on the victim machine:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
Policies\System "DisableRegistryTools" = 01 00 00 00


Other data is written to the Registry stored under the following key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\
CurrentVersion\explorer\%random string%

Where %random string% is a random text string.

The following values are stored here:

"Install Item" = (random string used for installed copy of worm in %WinDir%)
"Installed" = ... by Begbie
"Kazaa Infect" = yes
"Mirc Install Folder" = C:\Program Files\mirc
"Unfile" = buzf.qtq
"ZipName" = wqrqgd
The worm also displays a fake dialog window concerning a MAPI32 Exception. The user is prompted to submit:

email From name
login name/password
email address
SMTP server
POP3 server

The worm terminates various processes on the victim machine (see below). Interesting, the list includes "gibe"!

If one of these processes is started when the worm is running, a fake error message is displayed "Memory access violation in module kernel32 at (number)".

Infection Counter

Once running on the victim machine, the worm issues a HTTP request for a remote page which serves as an infection counter.

-- Update September 19th --

The original animated counter has been replaced by a warning message indicating the potential infection. In the text, the virus is referred to as W32/Swan@MM:

Removal Instructions
All Users :

Detection is already included in the Daily DAT files (beta) .

The following EXTRA.DAT packages are being made available prior to the regularly scheduled weekly DAT release ( working with EXTRA.DAT files ).

EXTRA.DAT
SUPER EXTRA.DAT
As stated above W32/Swen@MM disables the execution of REGEDIT.EXE.

This UNDO.REG tool will reverse the changes made by the virus and allow the user to execute REGEDIT.EXE as normal.

The changes made to the Registry to hook BAT, COM, EXE, PIF and SCR file execution (as detailed above) will be removed when cleaning with the specified Engine and DATs. For manual removal, these hooks are also addressed in the UNDO.REG file.

Additional Windows ME/XP removal considerations
