Spammers defies Bill Gates ‘magic Solution’

Paul

Sopho’s published statistics and I thought I would talk about it here.   Bill Gates promised to have a Magic Solution 5 Years ago.   Sophos Also provide a Chart of the Dirty Dozen:

dirty-dozen-q408

Sopho’s also is claiming that “US retains its crown as spam king“.    I don’t think so because of the the Other 32.4%.   The US can’t be the main culprit to spam.    So What was this ‘Magic Solution’ that they promised 5 years ago?

Microsoft has two techniques in mind for solving the spam issue, both based on the premise of changing the economics of email to place a greater burden on the sender.

Microsoft did have some good ideas but they wouldn’t work for right now because the first part of the ‘magic Solution’ was to add  mathmatical question to each and every email we sent out.   I know that this wasn’t going to work because hackers have already created a systems to get around the captcha verification.

[ad#ad2-right]Spammers of course are the ones  who is sending out the spam but they have people who write virus software, which I consider a hacker.  You see they want to infect systems so they can easily send out even more email.  When a system becomes a Botnet they usually are used to send out email.  If your curious as to what a Botnet is Check out the Wikipedia entry for further details.  So they need these systems to be able to send out spam, and other types of email phishing.   Most of the time a spammers  spam just for money because they make money by spamming people.   I hate spam because it clogs up our email accounts with unwanted emails.

So Did Microsoft come up with a fix?  According to Sopho’s they seem to be dropping percentages from 2004 to now in the US.   I have to wonder if Microsoft proclomation made them worry and go outside of the US.   I don’t think it will stop in fact, I suspect with the economy like it is we will undoubtedly start seeing even more spam and even more computer infections.

In order to prevent yourself from viruses and computer infections, you will need to install Anti-virus software and a Good firewall, not just the Default Windows Firewall.  This will greatly increase your chances of not getting a virus and possibly help prevent some of the spam.   You should also tell your associates or customers the benefits of preventive updates.  You should also remind people about not clicking links in emails and also not everything you read is true.

Security Researchers warn of potential flaws in Windows

Paul

I read an article today from Techworld. I wanted to Discuss this in detail. I also found some links that suggest that Techworld is right.

[ad#ad2-right]

Andrew Storms, director of security operations at nCircle Network Security, speculated that the latest bugs were found by researchers using information disclosed in SMB fixes Microsoft released in October and November.[va Techworld]

According to my investigation, and I have been looking. I found a few SMB Vulnerabilities. One of them is CVE-2008-4835 and CVE-2008-4834. These two are capable of Remote Code Execution, and are Consider very High on the Impact list and all.

So Did people find these exploits or vulnerabilities from the last MS 08-067 patch? I would have to conclude it is a real possibility.

Although Microsoft did patch those holes this month.  I grow to wonder just how much these hackers keeping the IT professionals on there toes.    I hope people updated their system to prevent another worm because you don’t want the worm like Downadup Do you?  I am sure there will be a worm or a virus that will exploit this in time, and I think sooner or later someone will use this just like the other one.

More Information on the downadup Worm

Paul

If your working to get rid of this Downadup Worm, F-secure is giving out a free removal tool to help with that task.   According to F-Secure Worm:W32/Downadup.gen description which Talks about how bad this worm is.

[ad#ad2-right]Due to companies not updating the MS 08-067 patch, it is the primary way for this worm to get onto a system.

Graham Cluely’s Blog ask a question and got quite a few answers from the users. The results of the poll are 53% believe the hackers are to blame, and 30% think the System Administrators are to blame, and 17% think Microsoft is to blame for this worm.

I have a mix feelings over who is to be blamed for this worm. I think the person who wrote this, did it for a specific reason. We can’t expect any software we use to be 100% safe, even Macintosh are not 100% safe. Microsoft isn’t to be blamed because they tried to patch this as quickly as they could. I know that companies have a hard time keeping up with Microsoft updates, and they really can’t be blamed. I think Hackers are always going to make a virus just because they can. That’s in there nature and we will never be really rid of the virus or worm writers. They are in it for the Money, to boast, to take control of, or steal sensitive information. Windows being the Alpha Dog, people are always going to test the waters because of that.

So who do you think is to be blamed?  I’d like to hear your thoughts on this.

Who do you think is to blame for the Downadup Worm?

1) End Users
2) Microsoft who did patch it
3) The person who Wrote this Worm
4) Companies who didn’t implement updates
5) No one it is going to happen
6) People who pay the writers of Virus/Worms

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:

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.

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
