Disaster preparation 101 — Data backup

Paul

In this one I will talk about Disaster, it happens to all of us from time to time. A fire, a earthquake, a stolen laptop or any number of ways. So what happens to your data, is it stored on the laptop? Is it important very sensitive data? Could you get fired if you lost that data?

[ad#ad2-right]These are all questions you must ask yourself when you have laptop. How do you backup your data or even do you have a backup? Having seen this with my own clients, I must wonder if there are people out there who just don’t care. I had a client the other day who gotten a virus and this was a really mean virus. Deleted some very important files when you tried to clean the virus out. She called me in a panic because she couldn’t load up windows? I asked if she had any backups, she said “what’s a backup” . So I sat there discussing this with the client for over 20 minutes. Finally she started to understand, she said she had the OEM Backup DVD but nothing else. She also said she needed help with getting data off the computer. I told her that I would be able to come the next day and I was lucky the virus didn’t do anything else to her data. We were able to retrieve the data from her system. That is where I start my rant , Why would anyone not have backup of there most important data?

So How do you backup your data? This is controversial and somewhat depends on how much people want to spend to keep there data safe and not loose pictures or music. There are several ways to do it, each way has it’s pitfalls or short comings and requires a little more effort:

Kinds of Backup

Hard Medium – DVD, CD, External Hard drive

Although,  The hard medium is usually used that doesn’t mean you can have a backup other than hard.   Here are some ways to back up on the internet.

Internet Medium:

  • Jungle Disk — Provides online storage through the Amazon s3 service.   Only pay for what you use.   It works well with most Operating system.  I’ve used it on Vista so it is really nice.

  • Carbonite Online backup –Another good Online storage.

  • Some Other Online backup — Here a list from Amazon to better help you find the type of software that you might need.

These are just a few options, if you want to look for other you can.  The important thing to do is BACKUP because if you need some data that gets wiped or destroyed.  You will be kicking yourself for not backing up.

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:

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.

Fix Shutdown Problems in Vista!

Paul

[ad]
In the Patch Tuesday update, Microsoft quietly released the patch to fix Windows Vista machine shut problems. This patch should of came sooner.

KB957388

Update for Windows Server 2008 and Windows Vista

Install this update to resolve a set of known application compatibility issues with Windows Server 2008. After you install this item, you may have to restart your computer.

This was not a critical update and it seems to resolve so many issues with compatibility.  One thing it seemed to fix on my system has been the shutdown time.  It is now quite fast, it would normally take me 2 to 3 mins to shutdown, now it does it in less than a Minute.   So if you’ve not installed this update please install it soon.   I would like to know if people are seeing the same thing I am.   I’ve found a great resource on fixing it if you are still having problem, it talks about how to check your system performance. Although this is been doing it lately with these programs not loaded or even running, they still seem to cause problems so now I get the feeling it has to do with legacy programs.  This should fix most of the problem with older programs.

Trojan.PWS.ChromeInject.A is not a Firefox plugin.

Paul

A new type of malware designed to harvest web passwords has been detected in-the-wild by BitDefender’s antivirus research labs. This latest e-threat – called Trojan.PWS.ChromeInject.A – is intended to be delivered onto a compromised computer system by other malware for subsequent download into Mozilla Firefox’s Plugin folder. Once installed it gets to work every time Firefox is started.

[Via Bitdefender]

[ad#ad2-right]So having seen this I thought I’d come up with ways around this to better protect yourself.  One way to prevent this from getting your sensitive data is to get a program like Sandboxie.   You could stop using Firefox that would be silly, because right now Firefox is more secure than Chrome and Internet Explorer.   I’d also suggest checking out my Anti-spyware page and Anti-Virus page and get some more protection.

The key to this virus protection is just be cautious of where you go and keep all you system update to date to prevent all this from happening.  It is also advisable to not have your passwords saved on Firefox, you should use something like Roboform, it is free  to download and try.  It will encrypt your passwords so if they don’t know the master password then they are out of luck.  Roboform is also good for coming up with some strong passwords.  Just some suggestions to prevent from people seeing your sensitive data, you don’t want anyone to get that data.

Are you patched, Secunia Says NO

Paul

Secunia BlogThink you’ve got nothing to worry about, according to Secunia 98% of computers are not fully patched and are vulnerable to some kinda of attack. [ad#digg-right]So I wanted to talk about this a little and give you a few good ways to make sure you are patched.  There are several ways to get your system up to almost 100%.

[ad#ad2-left]Some things to do is make sure you have your Windows systems updated.  This is easy to make sure, if you have an internet connection you can just check for updates.  If you don’t know how to do it, it is quite simple, Just go here.    If you have Windows Vista all you have to do is hit Start and type in the search box “Windows Update” and hit Enter and you will be taken to the update page.


If you have a system that is off of the Net you could use the Clone of Autopatcher Program to do it for you.   You also need to update all your secondary programs such as Audacity, Open Office, and other programs that you use weekly.

[ad#ad2-right]If you don’t know what you need to update sometimes just having a program check for you can make a really good difference.   The one that I like to use is Appsnap and it actually searches you computer to see what might need to be updated.   I also suggest for the final suggestion is check out my Anti-Virus and Anit-Spyware Resources and make sure you have a firewall and anti-virus software.  This will greatly reduce your chances of getting a virus but that isn’t all you have to be careful on what you click on read this article on Some Important programs to prevent yourself from having viruses and Malware!! Read that carefully to better understand how you can protect yourself in the future.
