‘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.

Warning Signs of Hard Drive Trouble

Paul

For every computer there comes a time when you have a problem with hardware or software. This is for those who want to learn the signs of possible fixes for having hard drive problems. Although if you know you’re hard drive is dieing then you better back it up as quickly as possible. You will of course need to get the back up software to protect your data.  If you have special drivers you will need to backup yours drivers.  If you have an OEM system then you will need to backup the Hidden Partition.

So what are the warning signs of a hard drive failure:

    [ad#ad2-right]

  • Unexpected freezing of Windows — When Windows Locks up and you have to reboot or getting a Blue Screen of Death.   You have no choice but to restart because you can’t do anything with windows.

  • Losing data files — if you seem to see files being lost or deleted without your direct input.  It might be a sign of a computer virus or it could be a damaged hard drive.

  • Locking up during boot — this is most common when you have a hard drive failure, although if you can restart and not be a problem then just keep in mind that it might be the beginning.  The more frequent you have the lockup boot problems the more chance of the hard drive dieing.

  • Hard drive isn’t recognized in BIOS– Although this can be a old hard drive, if the bios can’t see it then the problem might be a hard drive failure, usually this is meaning you just have to replace the hard drive.  there’s isn’t much you can do with this problem, just replace the hard drive.  Most of the time it is a problem inside the Hard drive bios and you really can’t fix this, you’d have to send it off to possibly save the hard drive data.

  • Clicking, Scratching, Whirling, Grinding sounds from Hard drive — This is the most dangerous signs of hard drive failure and means you need to get your data off ASAP.  If you want to hear some of the waring sounds of a dieing hard drive click here.

Although some of these can or can not be a hard drive failure, some can be driver issure or disk defragmentation and should be check out to rule out these problems.   There can be several problems that might be easily fixed.  If you think it is a failure you might try Spinrite.  The program is made by Steve Gibson and he actually has a “Absolute Satisfaction Guarantee“.  So if it doesn’t work or your not satisfied you aren’t out any money.  I’ve used this in the past for hard drives that are dieing so I could get all the important data off before it died all together.  It is essential that if you can get it working for a short time to get a backup.

Disclaimer: Although spinrite might fix some of the problems associated with a hard drive failure, it might not fix all the problems or any problems.   So it is left up to the user to decide if it is worth it or not to buy it.   I don’t recommend this for every situation or every problem only for the off chance that it might let you get the important data off the computer before you lose it.  Use at your own risk.

Signs of a Computer Infection!

Paul

So I was thinking this morning what I missed and I totally missed on how you might be able to tell if you have a computer virus. It does me no good to talk about a virus if you don’t know you’re infected. I was thinking of the times I had a client who had trouble but wasn’t what I thought.

So How do you know?

Some people would say it depends on factors but here are what I call clues that make me suspect a virus:[ad#ad2-right]

  1. Slow or Sluggish computers —  Here is what I know if the computer is really slowing down and have a dual core or quad core.  If you are running a system and sees a lot of hard drive activity even when the computer is idle then it might be a virus or it could be a program doing what it is supposed to be doing.  So this is somewhat of an indication but not always.

  2. Slow internet connection on the computer or on the network — Due to the fact that most people have a router that is connected to all the computers and if you internet connection on all your systems are slower than normal then you could have a virus.  I use Speed Test website to help determine this.

  3. Corrupt files or Missing files —  Sometimes you have a text documents or files that are missing and you have to pay to get them back.   It’s an old scheme and usually once your files have been encrypted you can’t get them unencrypted.  So this is why I added this one also because it varies from virus to virus.

  4. Programs don’t work like they used to —  This is also a very common association with a virus because virus makers don’t have time to test it out on a variety.   Most of the time if you get a call that a program is no longer working tat would be the first thing I’d look at, if not check to see what other programs have been installed lately.

  5. In some cases more files are the Hard drive —  This can be a indication of a virus because the virus might be using the system to host files or other such illegal activity.   Although this is happening less and less it can still be a possibility and should be checked out.   I like to use a graphical tree size program to determine if that is the truth.

  6. Pop ups or Browser redirects — this is a common thing along the way.  It’s always the same and saying something like “you have a virus” or “You unprotected and you might have a virus”.  The theme here is to scare the user into buying there product that does not do anything.   It sometimes even looks like a real anti-virus program or spyware program but in truth it is just a scam.  In some cases it will send you to a site because it keeps wanting you to buy the product.

  7. DNS Changes on you — Some hackers like to have you go through there server so they can watch everything you do online.  They are wanting to get the sensitive information of bank account, and other important accounts.  This is really the ones that need to get off your system asap.

[ad#ad2-left]These are the signs I’ve seen in the past that would indicate a virus but as with any problem.  You will need to check for all the possibilities.   It is always going to be an issue with people because most people don’t know about the signs, now you do and you can now be a better computer user.  It is you who can only fight viruses by knowing all the possible system and only you can defeat a virus.  In the next article I will talk about the tools to help you find and defeat a virus.   This will be a big blog post because I have so much to teach and explain.   If you like these post by all means leave a comment and help spread the word.

What is a Virus and Why do I have one

Paul2 Replies

After seeing more and more the updates coming from the net.  I wanted to talk about what a Computer Virus or Trojan is and how you get it.   So how did  you could of gotten a Virus in the first place.   So here are some information to consider:

The vulnerability of operating systems to viruses

So what does that mean to you?  Most of the times when you get a virus you have a vulnerability in some place in your Operating system and it is either something that has not be known by Microsoft, Apple, and Linux or is know as a Zero-day Exploit. [ad#ad2-right]

A zero-day (or zero-hour) attack or threat is a computer threat that tries to exploit unknown, undisclosed or patchfree computer application vulnerabilities. The term Zero Day is also used to describe unknown or Zero day viruses.

[Via Wikipedia]

This is one of the most used because if it is an unknown exploit by the Operating System creators then they have a longer to us the exploit.  Most of the time hackers like to use this because that means there is a possibility of finding even more vectors to infect other systems.  You see if they can get on one system they can then find ways to get on other systems.

In the Old days, you’d ask

How Did I Get This Virus, Anyway?

You get a virus when you copy infected files to your computer, then activate the code inside by running the infected application or opening an infected document. How you copy the infected files is irrelevant: Viruses don’t care if you get them as an e-mail attachment, a download, or via a shared floppy disk, though e-mail attachments are the most prevalent (and easiest) mode of transport.

[via PcWorld] (Dated Oct 13, 2000 11:00 pm)

That was before hackers wanted to infect for more personal gains.   There is a list of things that hackers want to get when they Infect a system and it is usually very few things.   In the Old days they wanted the fame but now they want money and to take control over the internet.  They usually want to infect for Money or to have computers become botnets.  Now We aren’t talking about the Movie, I Robot.   Once a system becomes a bot it doesn’t think for itself but follows a line of command from the Command and Control center.  So lets say we have  several hundred bots on one net, and the hacker blacked mailed a server saying if they didn’t pay up they’d get DoS attacked.  With enough bots going to one site at one time can slow or even bring down a site, that is how A hacker sometimes uses a virus or trojan to get into a system.

Viruses & Trojans try to Avoid detection

So you have a virus, it wouldn’t do a virus any good to be detected right after getting onto a system.   More and more, viruses are trying to avoid being seen and heard.  Most hackers who program are wanting to infect more than one system so they have to make really sure that you don’t find out your infected.    So with that said there are several ways  and I won’t try to explain them because I think the link talks about it better than I could.   It however will give people something to think about.

In the next few days there will be another post on How you will be able to figure out if you have a virus.  I had to talk about this first so people could understand how to figure out if you have in the next post.  So stay tuned for more

Vista has a new Vulnebility!

Paul

According to Techworld.com,  Vista has a new Vulnerability that could let a hacker infect a Vista machine with a rootkit.  The talk from them is quite intriguing.   I will quote it to better let you know what the Vulnerability is:

The vulnerability could allow a hacker to install a rootkit, a small piece of malicious software that is very difficult to detect and remove from a computer, Unterleitner said.

[ad#ad2-left]Phion notified Microsoft about the problem on 22 October. Microsoft indicated to Phion that it would issue a patch with Vista’s next service pack. Microsoft released a beta version of Vista’s second service pack to testers last month. Vista’s Service Pack 2 is due for release by June 2009.
[via Techworld.com]

The way they could do this is through the Device IO Control which in turn could corrupt the Kernel of Windows Vista.  Now we all know that Microsoft will release a patch quicker than 6 months away.  According to this article, people are already looking for the exploit and want to know more about it.  I would be willing to bet they will have a patch out sooner than later.  Probably January or Febuary, which will be a big deal because no one will expect it.  I would also imagine hackers will start trying to figure out how they could install software as quick as possible before Microsoft pushes out the patch.   So what can you do to protect yourself, Get a firewall, a Antivirus and learn how to protect yourself to prevent yourself from getting a computer virus.
