Stop botnets in its tracks With a Firewall!

Paul3 Replies

According to PC World and I’ll quote:

According to FireEye chief scientist Stuart Staniford, detection rates are so poor that, on average, only around 40 percent of security software can detect binaries during the period of greatest infectivity and danger, namely the first few days after a particular variant starts being used by botnet builders.

[ad#ad2-left]Now let’s talk about this, having been seeing recent surges of people getting infected.  I’ve come to the conclusion that companies like AVG and other Anti-Virus companies are keeping up.   Now true if all you have is an Anti-virus and nothing else that greatly increases your likely hood of getting a virus.

In a recent virus storm, We have people finding my site because of a Good Firewall.   No if he didn’t have anything but Windows firewall then it would of gotten through and you would not of known about it.  So let’s talk about how to prevent botnet attacks.   This is relatively easy and if you follow some common rules.   You to could be less likely to be infected.  I will say this most people don’t do these common tips and they should do them.

[ad#digg-right]So what should you do to help prevent from getting a Virus or Malware.  This is really simple, you want to find an Anti-virus Software that you like, and Firewall that you like also.  You’ll also want to download the tools to better help you in case you do get infected.  Some of these tools I recommend are Hijackthis, Spybot Search and Destroy, Hitman Pro, and Ad-aware 2007 Edition (FREE).  Then Go buy a Sandisk USB memory Stick and put those on there for later use!!  You will always want to keep a backup of those just in case you get infected.

[ad#ad2-right]Make sure you update Windows regularly.  Having seen this time and time again, if you don’t keep windows updated then you lose the battle.  If you have a system that needs updating, I suggest downloading the Clone to Autopatcher.  This little program will download the files needed to update your system without having to be online.  Although, you can have windows update automatically every month but that might not update the recommended updates only the ones that are hot.  It doesn’t matter which way you prefer to update, as long as you do to update regularly, Like every 2nd Tuesday of the Month.

One last tip you should also keep your Firewall and Anti-virus updated.  There is a little program that will do that, it’s call AppSnap.  If you follow all these recommendations you will greatly reduce your chances of getting a virus on your system.

Spying on Spyware.ISpynow!!

Paul

[ad#digg-right]This is another Virus that is going around and thought I’d tell you about it:

Spyware.ISpyNow monitors files, network traffic, and keystrokes. This Spyware gives the person who installed it a Web-based interface with summaries of logged information on the host computer.

[ad#ad2-left]Now this one isn’t to hard to figure out what happened.  You have to manually install it on your system to get infected.  Symantec has a great way on uninstalling this annoyance.  I also suggest checking out my other program list just in case you don’t want to buy Symantec Anti-Virus programs.  Some other things to check out is:

This is just the beginning in getting your system clean.  You have to keep all you programs up to date and one way I do that is with Appsnap.  This little program keeps you programs up to date from Virus to Firewall.  I hope this helps people prevent and control spyware.

Some program Vulnebilities Detected!!

Paul

Just got done looking at some of my security sites and according to SecuriTeam there are are several programs that have vulnerabilities. here are the Ones that I’ve found:

Google chrome is vulnerable to URI Obfuscation vulnerability.
An attacker can easily perform malicious redirection by manipulating the browser functionality. The link can not be traversed properly in status address bar.This could facilitate the impersonation of legitimate web sites in order to steal sensitive information from unsuspecting users. The URI specified with @ character with or without NULL character causes the vulnerability.

[ad#ad2-right]iPhone Configuration Web Utility for Windows Directory Traversal
iPhone Configuration Web Utility lets “you easily create, sign and distribute configuration profiles using a web browser”. A vulnerability in iPhone Configuration Web Utility allows remote attackers to access files that reside outside the bounding root directory of the program’s files folder.

Streamripper Multiple Buffer Overflows
Streamripper “records Shoutcast and Live365 MP3 streams to a hard disk, creating separate files for each track. Runs under Unix and Windows.” Secunia Research has discovered some vulnerabilities in Streamripper, which can be exploited by malicious people to compromise a user’s system.

Amaya URL Bar Stack Overflow Vulnerability
A vulnerability in Amaya browser allows remote attackers to cause it to overflow an internal buffer which in turn can be leveraged to execute arbitrary code.

These are the ones that I found and wanted to let you know about these so you can make your system even more secure.   if I find any others I’ll let you know!!!

Microsoft kills a fake antivirus tool from 994,061 computers!

Paul

According to Arstechnica and I’ll quote:

[ad#ad2-left]Win32/FakeSecSen has gone by various names, including Micro Antivirus 2009, MS Antivirus, Spyware Preventer, Vista Antivirus 2008, Advanced Antivirus, System Antivirus 2008, Ultimate Antivirus 2008, Windows Antivirus, XPert Antivirus, Power Antivirus, and Ultra Antivirus 2009. Furthermore, it is skinnable, so each of these variants has a different GUI, although the basic functionality is the same: bother users with warnings of malware until they pay up.

The Microsoft Malware Protection Center recently released some data on how the removal tool performed this month: FakeSecSen was removed from 994,061 machines. That number isn’t the highest Microsoft has recorded before, and the number of removals depends on which malware Microsoft adds each month and how widespread it is.

[via Arstechnica]

This seemed to of happened this month with the usual Windows update.  If you haven’t updated your system just yet you should.   This troublesome fake virus seems to have been killed  from several systems.  This could effectively make it harder for these guys who ever designed this program to make money.  I hope microsoft does even more virus removals in next month.  If you still want to try to get rid of these viruses don’t forget to check out my tips on Virus removal.

How to disable autorun the easy way!!!

Paul

I read a report from Cnet about USB devices spreading Virus and I will quote:

The bad guys are intentionally developing new flavors of malware designed to propagate through USB devices,” said Gunter Ollmann, chief security strategist for IBM’s ISS security division. “They are today’s floppy drives.”

[ad#ad2-right]An infected computer can spread a virus to a clean USB thumb drive that is inserted. That USB drive will then be spreading the virus onto other computers if the operating system on those machines has an AutoRun-type feature enabled. The AutoRun function in Windows launches installers and other programs automatically when a flash drive or CD is inserted. The Mac has an equivalent function, according to Ollmann.

[Via Cnet]

In order to disable “autorun“, which in Vista is called Autoplay. In order to disable Autoplay from starting when you insert media into your computer here is how you do it:

You will need to be Logged in as Administrator before this can be done:

Next click start and type “Autoplay” without quotes. It will bring up a screen but all you have to worry about is this:

Vista autorun

You will need to make sure there  is no check mark for “Use AutoPlay for all media and Devices”.   Click save and close.

[ad#ad2-left]Once that is done, you will have no more Autoruns from USB devices.  If you want to disable Autorun in XP, I’d suggest reading some of these articles for XP.

These are just a few and are really nice to articles but there are others out there that might be more to your liking.  I suggest searching Google for them.   I hope this helps you out!!!
