PDF Zero Day Vulnerability in the Wild

Paul

From sources all over the internet, Adobe made a sent out a Security bulletin yesterday:

APSA09-01 (Buffer overflow issue in versions 9.0 and earlier of Adobe Reader and Acrobat)

[ad#ad2-right]A critical vulnerability has been identified in Adobe Reader 9 and Acrobat 9 and earlier versions. This vulnerability would cause the application to crash and could potentially allow an attacker to take control of the affected system. There are reports that this issue is being exploited.

Adobe Plans on patching this March 11, 2009

and According to some other reports are saying:

Symantec Security Response has received several PDF files that actively exploit a vulnerability in Adobe Reader. We are continuing to remain in contact with Adobe on this vulnerability in order to ensure the security of our mutual customers.

[via Symantec]

With PDF files being used all over the business world, this will create undo problems with the IT Field.  This also could be used to make Botnets and make the network involved become sluggish.   It must be warned that there are a whole wide variety of possibilities that could be done with this exploit.  Shadowserver Foundation recommends disabling the Javascript in your Adobe Reader.  Until the patch comes out you will need to be careful on what you open up and possibly check each and every PDF with an Anti-virus.  This should help minimize the likely hood of getting a virus or Trojan, but is not going to be a 100%.  The only way you can prevent a 100% right now is not to use PDFS until they have Fixed this problem.

Zero Day For IE7 Being used in the wild.

Paul

It looks like IE7 patches are being used right now in the wild.  According to TrendMicro:

HTML_DLOADER.AS exploits the CVE-2009-0075 vulnerability, which is already addressed by the MS09-002 security patch released last week. On an unpatched system though, successful exploitation by HTML_DLOADER.AS downloads a backdoor detected as BKDR_AGENT.XZMS.

How the IE7 Exploits are being used

[ad#ad2-right]As you can see this this can be very bad for the companies who wait a while.  Internet Explorer is still being used 1 out of 4 users and I see it it all the time on my stats.   The Good news is this isn’t as hard to get rid as the Conflicker but should be taken serious because the writers might start to want to get even more malicious and make it even harder.

This is the next step to prevent yourself from getting caught with your pants down so to speak, you need to patch all systems that have internet access.  I still like the Autopatcher because it will do the job with very little input from the user.   It also makes it easier for people to patch big systems.  You should also consider installing some Free Anti-virus software to help protect the systems you do have.

From the looks of this virus, someone could easily make this into a botnet and you know how that can could affect your systems and your ISP.  So it is best to get this months patches on the floor of your company as soon as possible.

You should also consider telling your users to start using Firefox to prevent infection from even happening. Until you patch, you are vulnerable.

Internet Security Companies Warn about Patch Tuesday and Valentines Day.

Paul

With Tomorrow being released some very highly rated Remote Code Execution to become Zero day in very short time. Some researchers are speculating about more viruses will be released in conjunction to Valentines day. According to this one post it will be likely to be E-cards being sent to try to lure you into downloading Malware.
[ad#ad2-right]

Various security vendors, including CA Inc, MX Logic Inc., Trend Micro Inc., and Panda Security, have issued alerts about new Valentine’s Day-themed spam campaigns that try to dupe users into installing the Waledec bot.

Researchers note that many websites which are affiliated to Waledac e-card scam have been recently updated with content based on the Valentine’s Day theme.

Web sites distribute Trojan files which are commonly named love.exe; onlyyou.exe; you.exe; youandme.exe; and meandyou.exe and the list is not exhaustive.

So which ones will likely be the exploits they will use? I have a few theories on that and One of them is the INTERNET EXPLORER vulnerability that will be patched and will try to get you to launch the link and will most likely try to launch it in Internet explorer, That would be my guess.    It seems to be Internet Explorer 7 and Below which will be patched so if you want to try out the IE 8 Beta,  You should be safe on that.  Although the best bet is to prevent users from clicking links in emails and also warning them not to open any attachments they are not expecting.    I’d also have the AutoPatcher ready to install the lastest patches for this Tuesday and schedule a time this week to update all the possible systems involved with the Databases.  Although this isn’t one that tries to steal your data it is however a chance the writers to look at what you have and you know how that can be call a data breach.   So if your the IT for the department I’d suggest sending out warnings so they can keep from being caught with their pants down.   I’d also suggest having Anti-Virus and free Firewall installed on all the major systems and it wouldn’t hurt to have the installed on minor systems if at all possible.

Offline Update 5.0, Clone of Autopatcher to Some!!

Paul

Offline updater 5.0 has been released a couple months ago and I just realized it now.  This is an excellent tool for IT professionals who want to keep all your Systems up-to-date with the last patches from Microsoft.  The systems it supports are Windows 2000, Windows XP, Windows Server 2003, Windows Server 2003 x64, And Windows Vista / Server 2008.(32 bit and 64 Bit updates).

ct-offline-update50

[ad#ad2-right]I find this a very useful program for people who have a multitude of problems, from not being able to get on the net to computer virus infections.  This is really good for big businesses that want to update a lot of systems in easy way without having to wait for downloads of updates to install.   You can take a DVD and update on the fly within Mins.   DVD being Cheap or buying them in bulk helps saves time and money for the company.   Less time spent downloading the updates and more time actually getting work done.  As with the Conflicker, Downadup, and to some the Conflickr Trojan, if you got infected with that little worm.  This would help install the updates that it prevented you from doing in the first place.  I also found that once you download do the update the files are kept on the hard drive so you no longer have to redownload them again.  You just update the updates every second Tuesday of the month and it downloads the newest patches and creates a whole new ISO for you to burn.

Q: How can I create the offline update CD images automate, for example via a “scheduled job”?
A: Create a new batch file in the “cmd”, eg “DownloadUpdatesAndCreateISOImage.cmd”. Add the desired calls of

“DownloadUpdates.cmd” and “CreateISOImage.cmd” with the necessary parameters in this new file. The file might for

example have the following contents:

@ echo off
call WXP download updates eng
call CreateISOImage WXP eng

Then set a “time-controlled contract” for the new script “DownloadUpdatesAndCreateISOImage.cmd” to your desired

time. For example, after each Microsoft Patchday create new images, select every second Wednesday of the month.

[Via The FAQ’s Documentation (Translated Via Google)]

As you can see you can have it do a script and be ready for you in the morning.  You then just take it out of the drive and install where you need to install the day after the updates are issued. On another Note if you have clients who use Windows office Xp, 2000, 2003, 2007 then this will also help:

ct-offline-update50-1

This is nice if you have clients who use the Microsoft Office Suites also.  Some Malware will often try to infect people’s systems through a office script or some other vector.   So this will also prevent infections or hackers from getting onto the system by updating this also.  You can have this added to each and every DVD ISO you make to include these as you update the patches also.

Phishing sites pop up for IRS!

Paul

Well, this just came to light with The Spywareguide blog. I’ve seen some activity about Where’s my refund lately and I thought I tell you how to make sure you’re on the right site. If you’re expecting a refund check the OFFICIAL SITE. The Official Site is http://www.irs.gov and nothing else. If you want to find out about some of the most common Phishing attempts check out the Phishing advice from the IRS.

[ad#ad2-right]The Spyware Guide blog talks about sites that looks to be IRS but are actually just phishing for information.  Some of the ones they talk about are:

gicrisis.org/data/refundtax/SearchTAXERR.php

irs-2009.com/refund/refunds.html

collectrefund-irs.com/refund/refunds.html

cimaonline.ca/application/Internal/Revenue/Service/pas.php?certegy_vm=trueportlet_change_1_actionOverrideFchaseonlineFchangeFprocessDetails_windowLabel_portlet_process_pageLabel_page_process

jklabs.cz/phpayv2/admin/import/.secure/www.irs.gov/get-refund/refunds.php?Where_is_my_refund&Get_Refund

Although this list will most likely change this is just starting for people who filed there income tax. Some things to Remember are:

You can generally access information about your refund 72 hours after IRS acknowledges receipt of your e-filed return, or three to four weeks after mailing a paper return

Via IRS.GOV

So if you’ve filed your Taxes it should be getting to you in 3 to 4 weeks although as you get closer to the March 15, 2009 Deadline it will take longer so you should consider filling early to prevent from having to wait to long for your return.  If you follow the rule that any email claiming  to be from IRS is not true and shouldn’t click or install any software.  You should however tell the IRS as quickly possible about this attempt to get sensitive information.  If you want to protect your  system from virus or even think you have a virus, trojan, or Malware please check my Malware Resource for further information on removing it!!
