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!!!

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.

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!!!

A good free VPN Client — OpenVPN & more

Paul

I’ve been doing some research on what might be good to use in case, I was away from my home network.  I was thinking how safe am I at Starbucks or other places that I might doing my web.  So I did a little looking around to see which one I liked and I came to the conclusions that only one I need right now is:

openvpn

The nice thing about this was the simple installation of the software and how easy it was to set it up. This service is in beta but seems to be really well done with regards to the end users. When you install this software and want to connect it uses the OpenVPN software with there configurations. OpenVPN, is a open sourced SSL VPN solution and is free to use. The way this this free is of Ad Supported banners. Now it is cheaper than paying monthly for a VPN service. The ones I’ve found so far are these few:

  • OpenVPN (FREE)(*advertisement)(Linux, and Windows)

  • Always VPN (Prepay) (5 GB to 80 GB limit) (Linux, Mac and Windows)*Out of Beta

  • Hotspot Shield (FREE) (*advertisement) (Windows) (3 gig Cap)

  • WiTopia (40$/ Year) (Mac, Linux, and Windows)

[ad]There is of course others out that but these are just a few that I saw that looks like the cheapest there is.  Others I’ve seen cost 40 to 50 dollars a month.   If you have any other ones that are free or cheap let me know.  I don’t think we need to pay a lot just to have security on an open network. I’m certain that they’re more out there but will keep looking for more later on. I did my initial research and will come back and find more.

*Update Feb 8, 2009*

As of recent a friend emailed me saying telling me to check the site out again and I did.  Not sure when they went out of Beta because I’ve not been using Always VPN lately due to my Broadband Cricket Prepay Internet.  I just checked and yes they are charging here’s the break down:

  • 5GB – USD 8.50

  • 10GB – USD 15.00

  • 20GB – USD 26.00

  • 40GB – USD 33.00

  • 80GB – USD 47.00

So I must ask why they didn’t just keep the 5 GB limit with the Advertising, I do not know but  I did want to let people know that it is no longer free and no longer in Beta.  I went from Always to OpenVPN which still works despite the fact they are using Always VPN back client.   It’s open source so it will probably change to something else sooner or later.   If you see it changes let me know, I will update more when I find out more!!

AVG Detected a False Positive

Paul3 Replies

[ad#ad2-left]According to Security and The Net:

An update for the AVG virus scanner released yesterday contained an incorrect virus signature, which led it to think user32.dll contained the Trojan Horses PSW.Banker4.APSA or Generic9TBN. AVG then recommended deleting this file; this causes the affected systems to either stop booting or go into a continuous reboot cycle. So far, the problem only appears to affect Windows XP, but there is no guarantee that other versions of Windows don’t have the same issue.

[Via Security and The Net]


[ad#ad2-right]I bring this up because this is a false positive according to AVG. AVG since sent out another update to there Database and you can go and update the database to get rid of this problem. If you need to restore that DLL check out the article Security and The Net, they got some excellent suggestions on fixing the problem.

If you’ve not been affected by this yet, you probably won’t be. It is yet unknown how many people have been affected. I’m blogging about this to tell people about this and to warn people that not all of warnings from AVG are true and that is why you should always ask before you delete or do anything to your system. I always USE google when it comes to these types of questions

Reports are coming in that WPA is no longer secure!

Paul

[ad#ad2-left-1]

According to a media reports, Erik Tews and Martin Beck claim that they have found a way to unlock the Temporal Key Integrity Protocol (TKIP) key, used by WPA, to read data sent from a wireless router to laptop computers. According to the researchers, the key can be cracked in 12-15 minutes.

[via Sophos]

According to Sophos, they are claim that people can now watch what you are doing on a Wireless router to a laptop. Although this isn’t to be unexpected this is a very serious out come. It is now easier to watch what people are doing online. So does that mean people can see everything you do? Not necessary. According to some people this is harder than it seems, most of the websites you visit are not encrypted, but websites that use the “https” protocol are more safer to use online. You should be safe if you are buying things online as long as you are sure it is secure. Some other steps to take to help make it harder to unencrypte your wireless single is to use Roboform promotion codes you will get for 10% or 20% off the purchase price!!

[ad#ad2-right]Some other steps to consider are:


If you have a wireless router and want to be secure with any transactions online you might think about hooking up to the internet via the CAT5 cable.  This is one way to prevent anyone from seeing what you are doing online and protects your privacy.  Although this too can be overcome in certain circumstances they are much harder to do and implement so you are safer this way than with most others.
