‘Life Owner’ won’t delete your data!

Paul1 Reply

I received this email from a friend and wanted to talk about this:

VERY IMPORTANT , PLEASE READ THIS

Anyone-using Internet mail such as Yahoo, Hotmail,
AOL and so on.

[ad#ad2-right]This information arrived this morning,
Direct from both Microsoft and Norton

Please send it to everybody you know who has
access to the Internet.

You may receive an apparently harmless e-mail titled ‘Mail Server Report’

If you open either file, a message will appear on your screen saying:
‘It is too late now, your life is no longer beautiful.’

Subsequently you will LOSE EVERYTHING IN YOUR PC,
And the person who sent it to you will gain access to your
name, e-mail and password.

This is a new virus which started to circulate on Saturday afternoon.
AOLhas already confirmed the severity, and the anti virus software’s are not capable of destroying it.

The virus has been created by a hacker who calls himself
‘life owner’.

PLEASE SEND A COPY OF THIS E-MAIL
TO ALL YOUR FRIENDS, And ask them to
PASS IT ON IMMEDIATELY!

THIS HAS BEEN CONFIRMED BY SNOPES.

http://www.snopes.com/computer/virus/mailserver.asp

After doing my little research, I’ve come to the conclusion that this is nothing more than a warning that someone went over board on. I’ve check this on Snopes and it says that:

This latter version is difficult to classify as either “true” or “false”: The virus it references (i.e., the Mail Server Report worm) was a real one, but it’s neither new nor currently rampant (as claimed in the warning text), nor does it manifest itself in the fashion described (since the “symptoms” provided in the warning are merely a reworking of the text of an earlier virus hoax). All in all, that message doesn’t really merit the dire warning to “SEND A COPY OF THIS TO ALL YOUR FRIENDS, And ask them to PASS IT ON IMMEDIATELY!”

I decided to send a reply to my friend who email me this “Warning” and tell him this:

[ad#ad2-left]Although,  This is a real worm.  It however is over hyped and under no circumstances will it delete your files.   I’ll quote from F-secure:

Warezov.W is a mass-mailing worm that sends itself as e-mail attachments to addresses found on the infected computer.

Typically, a mass-mailer arrives on a computer with an infected e-mail message. In some cases, the infected attachment can start automatically. In other cases, the system is infected when the user opens the attachment. When a typical mass-mailer is activated, it installs itself to the system and creates a startup key for itself in the Windows registry. It then stays active in the system’s memory. While active, the mass-mailer searches for specific files (HTML files for example) on all available hard disks for e-mail addresses. Finally, it connects to an available mail server and sends itself to all the addresses it has found.

Aside from this, Warezov.W also downloads another worm variant from a specified website on the Internet.

According to all my sources is if you are worried about this worm, then I highly recommend a good Anti-virus and Software firewall.   This worm is easily detected by all the free anti-virus software out there.    I like AVG because it scans all incoming emails before you even touch the email.   Please don’t forward that to anyone else it seems to be an old email warning that isn’t really a warning anymore.   It seems to be a scare email where there is no real chance of your data going bye bye.   Just thought you’d like to know!!

So I tell you this, if you have any question of the likely hood of any emails you happen to come buy, you best best it to google it or ask your friend before you open the email up.   It is best also to scan all email attachments before even considering opening them.

Uncovering a Virus/Trojan

Paul

Getting done with the first part really got my juices flowing. I was shopping looking and thinking about this next article. I came up to only one option turning this into a 3-5 length post due to all the content that I will have.  So where did we leave off?  Oh that is right figuring out if you have a virus/Trojan.  The instant I made a post about this 12 hours later someone make a comment and here is what he said:
[ad#ad2-right]

Rene Van Belzen

I can’t wait to read part two of this article. I always wondered how you’d know you’re infected if a virus don’t want to be detected and no virus definitions are yet available, because the virus is so new.

Now the truth is anytime a Virus does something it usually leaves a footprint somewhere and somehow.   Even the hardest working hacker can’t plan for all possibilities and that is where we begin.   I have been helping people for a while with viruses and know that no matter how hard the virus tries to hide you can usually find it relatively quickly and easily do to virus check here are the ways I’ve done to figure out if they may or may not have a virus/Trojan.

Now if this is a client’s computer and you don’t want to be rude to the client, there are a few indications of user error and installing a virus.   This is relatively simple, all you do is do a quick inventory of all the start menu programs.  You’d want to look for any P2P file sharing program, If they have Firefox Installed, and if they are using Window Mail and not Thunderbird.   You see 80% to 90% of virus downloaded are installed by the End USER.  They either downloading a game and installing a virus with [ad#ad2-left]a game, or not protecting themselves by using Internet Explorer or Using Windows Mail.  That is usually my first step due to the fact, I’ve got to be diplomatic about finding out about security ways.  Also make sure they are up to date on there Window updates, unless they are using a really old system then you will have to work even harder.  Also you can suspect a virus if the client is talking about having problem with a program recently although this isn’t always true it sometimes is the case due to the fact hackers don’t have a big chance to test these viruses/Trojans out before they set them into the wild.  So there are always going to be unplanned problems associated with them.

After the first initial search of desktop, you should really know the likely hood of a possible virus getting on the system and later we will talk about counter measures to prevent virus attacks in the future.   There are a few places a hacker likes to put commands.   Hackers love to put in the Registry to run a program every time Windows starts.  It usually in:

  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\

Usually 50% to 70% of virus like to make sure the program to runs.  This is a flaw in Windows because hackers can edit this without much effort but there isn’t many places a hacker can go to make sure a program is set to run when you boot.   So this is also a benifit to finding those little programs.

Now just like the Regisitry, Hackers also like to put programs in a few areas on the hard drive.   This is also kinda hard to hide because most of the time these are consider important to the system but if you know what to look for you can pretty much figure out if it is truelly a system file.  These areas of the hard drive are:

  • C:\WINDOWS\System32[ad#ad2-right]

  • C:\WINDOWS

  • %programfiles%\common files\microsoft shared

  • %windir%\temp\

These are just a few but if you look hard enough it can be found most of the time.   Most of the time I use the registry to tell me where these programs are so I can do a further check of the program.  Some of this is not needed with some of the programs that I recommend but this is for those who want to be a through job and make sure the virus is gone.

On my next post we will talk about some good tools for the trade to help get rid of a virus/Trojan.  This little step here is used to  better help identify a virus and also give you chance to google each name on the list of registry and the hard drive  to see if you can identify the virus.

The Important Windows patches Released Today

Paul

As many of you know we talked about the Non-critical patches that Microsoft will release today.  IF you want to read those please go and check it out.   I’ll be talking about the REALLY important ones that Microsoft has kept tight until now.    These are the more important ones but I will list the ones that I previous talked about to better help people recognize the non-important ones:

[ad#ad2-right]

  • KB955839

  • KB957388

  • KB890830

  • KB905866

    • These are just the tip of the iceberg. although this list are not A lot.  I’d wanted to let people know about what people coin “Exploit Wednesday“.  I really don’t know if this is a Myth or actually does exist but I’d figure we discuss the problems associated with installing the critical updates and try to tell you which ones should be installed As soon as possible.  Though people have in the past used a Virtual Machine to see if there is any problem, that should be your first step if you don’t want to have any problems with these updates.  I don’t suggest testing it more than a couple days.  Here are some good Virtual Machine software to try out yourself:

    Here is the list of updates that are critical that Microsoft released today.   Each one of these are quite important and should be considered installed when you get a chance.

    [ad#ad2-left]Microsoft Security Bulletin MS08-073 – Critical
    Cumulative Security Update for Internet Explorer (KB958215)

    This security update resolves four privately reported vulnerabilities. The vulnerabilities could allow remote code execution if a user views a specially crafted Web page using Internet Explorer. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

    Microsoft Security Bulletin MS08-071 – Critical
    Vulnerabilities in GDI Could Allow Remote Code Execution (KB956802)

    This security update resolves two privately reported vulnerabilities in GDI. Exploitation of either of these vulnerabilities could allow remote code execution if a user opens a specially crafted WMF image file. An attacker who successfully exploited these vulnerabilities could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

    [ad#ad2-right]Microsoft Security Bulletin MS08-075 – Critical
    Vulnerabilities in Windows Search Could Allow Remote Code Execution (KB959349)

    This security update resolves two privately reported vulnerabilities in Windows Search. These vulnerabilities could allow remote code execution if a user opens and saves a specially crafted saved-search file within Windows Explorer or if a user clicks a specially crafted search URL. An attacker who successfully exploited these vulnerabilities could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

    KB952069
    (not quite sure what this one is, when I go do a Google search this is what pops up. It was in German but Google translated it for me)

    In the Windows Media Runtime to the default in Windows XP SP3 contains Windows Media Player (WMP) 9 were discovered vulnerabilities that could allow an attacker to compromise your Windows-based system and gain control over it. See Security Bulletin MS08-076 ( englisch bzw. deutsch ) See Security Bulletin MS08-076 (English or German)

    These are just ones that I found and wanted to let you know, the others have been explained on the other article.  So check them all out and I suggest installing them quickly as possible.
