Harms Done By Win32.Auto Run On A Computer

Most of the Top 10software companies in India would list the Win32.AutoRun a low risk virus and this is true. But this virus can be extremely bugging if it is not taken care of on time. The sooner it is taken care of, the better it is.

This virus propagates through removable storage devices and there are symptoms which indicate that a computer is affected by this virus. Visible symptoms that indicate Win32.AutoRun is affecting a computer are listed below.

When operated, the worm copies itself in the %programfiles%\Microsoft Common\ folder under the file name – wuauclt.exe and the registry given below is created.

[HKEY_LOCL_MACHINE\SOFTWARE\Microsoft\Windows NT\ CurrentVersion\Image File Execution Options\ explorer.exe] “Debugger” = “%programfiles%\Microsoft Common\wuauclt.exe”

This then cause the worm to execute on the start of every application.

You may wonder how do I get to know all these. It is because I get maximum cooperation from the software engineers working in Oglacs, a top software company based in India.

Continuing, I would like to tell you that this worm runs and create a new thread with its own program code inside the following processes:

This worm copies itself into root folders of removable drives using the name – system.exe. A file, autorun.inf is dropped in the same folder. This then ensures that the worm is started every time an infected media is inserted into a computer.

The system.exe file is a copy of the worm itself, while the autorun.inf contains the following strings:

[autorun]
;p
open=system.exe
;p
shellexecute=system.exe
;p
shell\Explore\command=system.exe
;p
shell\Open\command=system.exe
;p
shell=Explore

The Win32.AutoRun worm contains a list of URLs from which it tries to download several files. HTTP protocol is used and files are then executed.

The worm creates files as %temp%\%variable%.tmp (6656 B)

It may also set the following Registry entries:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\ CurrentVersion\Winlogon] "Userinit" = "%system%\userinit.exe,%variable1%"
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\ CurrentVersion\Run] "%variable2%" = "%variable3%"
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ SharedAccess\Parameters\FirewallPolicy\StandardProfile\ AuthorizedApplications\List] "%variable4%" = "%variable5%:*:Enabled:%variable6%"

Win32.AutoRun may also create files given under:

%System%\config\autorun.inf
h:\autorun.inf
f:\autorun.inf
i:\autorun.inf
g:\autorun.inf
k:\autorun.inf
l:\autorun.inf
o:\autorun.inf
j:\autorun.inf
These files will be launched each time the user opens the corresponding hard disk partition using Windows Explorer. When one of these files is executed, it will launch a copy of the virus as %System%\config\csrss.exe.
Win32.AutoRun may also infect the following files:
%AllUsersProfile%\smss.exe
%AppData%\microsoft\windata\__arestra__best.exe

Win32.AutoRun – Brief Account

Let me today switch my attention upon another virus of the worm type known as Win32.AutoRun. This is something which I never knew until I start working in Oglacs, one of the top 10 software companies in India. I have seen the copies of the virus in my own system long ago but I thought it was normal and it may have been a system file but I was wrong.

Copy of the virus is encircled

Win32.AutoRun is low damaging virus of the worm type. One thing I'm surprised is that this virus has got versions and its size depends upon the version. This virus is also known as Worm.Win32.AutoRun in Kapersky, Spy-Agent.bw.gen.trojan in McAfee and W32.SillyFDC in Symantec.

I came to know all of these for I was told about it by those software engineers working with me. The credit of this top software company goes to all of them. As according to them and when I searched it online, this worm came into being or first appeared on 10^th October 2007. The damage done by this worm to the computer is low but it can be most bugging to computer users.

They propagate through removable devices. Therefore, be careful when you are about to insert your media storage devices on any computer.

How to avoid and delete the virus will be posted in the next post. So come back for more.

Beware!! You May Have Downloaded A Virus

Most of us nowadays thinks that downloading stuffs online is the coolest way. But a fact one should know is that when we are doing that, we are putting risk on our computer from getting infected by virus which comes with downloadable files. These files can be of any form. It can be a document attached in an email, banners, advertisements, music, torrent, etc. and even from those online dating personals you come across dating site. Therefore, one should be careful while downloading anything online or exchanging links.

Being one blogger amongst the many software engineers here in Oglacs, one of the top 10 software companies in India, I would like to suggest everyone that they should install an antivirus software and get it updated frequently. Set the risk or virus attack notifier of the software so that you may be notified of any virus, malware or spyware.

Now coming to torrent, why would anyone would like to buy movies CD when they are available online for free. What happens with torrent is that these files are being shared via an uploader then seeders. If the uploader is up to some mischief, he might have put malicious program along with the movies, music or pictures you are about to download.

Sharing file using a pen drive is also risky. Say if you have a system without an anti-virus software installed or haven't been updated for days, you are risking your computer when you are transferring any file from a friend's computer which is infected.

You may have doubts, “How can I be so sure?”. The thing is that, I'm sharing the little things I know since the day I started working in Oglacs, the topsoftware company I have ever worked. Virus infection on your computer can be due to many sources. So check your PC for infection, install antivirus software, run a full system scan and remove the viruses.

Virus In Your Computer - Explained

Are you experiencing an extremely slow computer? Do your computer shuts down by itself without any command? Are there none deletable files and unknown applications in your system. If yes, your computer is probably infected by viruses. Your computer needs an immediate fix on it. The question is, what should you do?

First of all, ensure that your computer is infected. If it is, see whether you have an anti-virus installed. If not, get yourself an anti-virus software and have it installed in your system. When you get yourself an anti-virus software, you should make sure that the software development company (it can be one of the top 10 software companies in India in case of people in India) that develops it is trustworthy. If you have it installed in your system, make sure it has the latest updated virus database so that it recognizes every virus in your system and fix or remove them.

Updating of virus data base is done by connecting to the internet and clicking on the update button of the program. If you have no connection, you may go to the nearest internet cafe and download virus database update of the particular software installed in your system. Once you are done with the updating, run a whole system scan of your computer.

All detected viruses will be quarantined. You can select each one of them and do the manual fixing. Try fixing the infected program or files and if that is impossible, you may try removing them only if it doesn't affect the system's proper function. Or else you may have to format your system of which I'll post later in the blog.

This is not all, you may check Ogalcs' blog, a top software company's blog later.

How Are Emails Harvested By Spammers? (Part 4)

The next time you fill up any web form or any paper forms you should think twice for today as a continuance to my previous postings, I will yet tell you another method Spammers use to harvest emails. The method which I am talking about is harvesting of email through web forms and paper forms. Many top 10 software companies in India have fallen victim to this kind of email harvesting.

How is this possible? There are sites you should be aware of. These sites have forms for you to give your contact detail. Cases have been there in which the emails hence provided by site visitors are being sold by the company to spammers. Therefore, you should make sure that the site is trusted before you give them your email address or you should make sure that by providing them your email address, it is not going to be available in the world wide web. By saying this, I don't mean that all sites that have web forms are untrustworthy. As for instance, Oglacs being one trusted top software company has web forms in the contact us page but we spam proof all our pages and there is no chance for spammers to get through it.

There are programs that spammers use to get email addresses from such web forms. You should also watch out for sites that sell email addresses to spammers. Emails are also made available to spammers through paper forms. Organizations and companies also sell these papers which has email address of individuals to spammers when they can no more make use of the papers.

Whom do we trust now?? The worlds has indeed changed. Now that you know, you can be aware of such actions by companies and sites.

How Are Emails Harvested By Spammers? (Part 3)

How do spammers harvest email? This is the topic I have been talking about and will for some days. This is because I understand the frustration email users undergo when their email account is filled with spam. Not only individuals but also top 10 software companies in India too undergo such bad feelings.

Continuing the topic today I will speak about another method spammers employ to harvest emails and that is:

From Web Pages

Spammers uses programs which can crawl or spider through web pages looking for email address mentioned in HTML tags. In this way they can harvest emails from web pages. The question arises, is there any remedy for such step?

My answer would be, “yes”. Even the top software company uses this method to avoid spam. The technique hence used is the “poison” CGI script. This script creates a page with numerous phoney email-addresses and a link to itself. When such spam spiders or software visits the page and try to harvest emails, it will harvest the phoney email follow up the link which is linked to itself hence get caught in an infinite loop.

Check out form more in the next post. If there is any query or suggestion, just leave a comment.

How Are Emails Harvested By Spammers? (Part 2)

As a continuation to the previous post, I will here today talk on another way how spammers harvest email addresses. The way of harvesting email here I am talking about is “from mailing lists”. This method doesn't spare even the top 10 softwarecompanies in India or elsewhere.

In order to get maximum number of emails, spammers usually attempts to get access to mail servers. Upon request by the spammers, some mail servers will give those to the spammers. Most email addresses gained this way are valid only some of which are masked and invalid.

For mail servers that are configured to refuse such request, spammers use another trick to gain the list of emails. The trick hence used is to send an email to the mailing list with headers X-Confirm-Reading-To: <email address> or “Return-Receipt-To: <email address>. This way spammers will know when the sent email has been read by the recipient or delivered.

Another technique of spammers is requesting mailing list server to give them the list of mailing lists. If in case a mailing list server accepts the request, the spammer send the spam to the mailing list address and the rest is done by the mailing list server.

As said before, even though Oglacs is one top software company, some email addresses of the company are not spared by spammers.

Still to continue......

The question here is, how do spammers harvest emails? There are certain ways spammers can get your emails. Here is one of the many which I will discuss in the blog today. This method is:

Getting Emails from Posts to Usenet using your email address

Spammers are so smart that they know where and when internet users post on forums and other topic under discussion in the internet. Spammers scan Usenet to gather email from article, press releases and other web contents. They use ready-made email harvesting programs. These programs herein mentioned are well designed to recognize email. It is also programmed to select all content containing the character @ and get a possible email out of it. It also happens that these days there are programs that can even undo email masking i.e. removing “nospam” from emails.

Spam Avoiding Tips

It's really annoying when your email, you IM and even your personal forum is filled with spams. Here today I am posting some methods to avoid spam flooding your email. Here are the methods and mind you, these methods are effective and are used even by top 10 software companies in India and elsewhere too.

Masking your e-mail address

The most common way to keep away spam from your email is to mask your email. By masking your email means the putting of a word or phrase in your email address so that it will bluff harvesting computer programs but not human. As for instance your email is “marktwain@jingle.com” you may mask it as “marktwain@spamaway.jingle.com”

Using a Pseudonym During Chat

If you are someone who use chat rooms for chatting, make sure that you use a different name which is not related with your email address. This will not allow spammers to know your email address while chatting.

Use Disposable Email Addresses

This is a method used by even the top software company, it is also considered one of the most effective ways to keep away spam. Use disposable email service that allow you to create separate email addresses but forwards the mails to your permanent account. If any of the the addresses you created starts receiving spam you can get rid of that address. This will not affect your permanent account.

Use Unique Email address

By unique email address, I mean to say that the email you will be using in public should contain both letters and numbers. This will stop those spammers who use “dictionary attacks”, a way to email to all name combinations within a large email service.

If you follow the above methods of avoiding spam, you will considerable reduce the amount of spam flooding in your email or even put a stop to it.
