comment Swap file may contain sensitive data
Lets say I set up Debian with encrypted LVMs (standard setup) would that mean this is set up?

comment Swap file may contain sensitive data
Nice one. Is there a similar easy fix for Linux without using protected memory?

comment What are the main weaknesses of mobile software based OTP generators?
Agreed. It would be easy to reverse engineer the OTP-generation algorithm and learn future passwords.

comment Is this a ViewState attack?
Is this the only occurrence from this IP? For me the suspicious part is the " ' " character, which is often used for probing SQL injection vulnerabilities.

comment How to perform security exploits/penetration on devices like iPhone's, PSP's, and Android to run your owncode?
No need to apologize :) I like the question, but maybe it should be broken into multiple more specific ones. And I too am very interested in this topic. For reference I've been testing Android apps and this might point you in the right direction for that: intrepidusgroup.com/insight/2011/05/androidaudittools and wsec.be/blog/2011/10/05/adventures-in-pentesting-android-apps

comment How to perform security exploits/penetration on devices like iPhone's, PSP's, and Android to run your owncode?
I think you should be more specific - as each device is different, how you exploit or pentest each device is inherently different. At least technically. Many of the principles are of course the same as with all clients, be it a Windows computer or an Android device.

comment Is accessing bank account on the internet really secure?
@AviD just a typo, I meant authentication of course. But in Norway where I'm from I have not heard of any bank that don't use two-factor authentication. I actually thought that was a requirement for PCI compliance, but of course it might just be an "extra service" our banks provide.

comment Does strong naming remove the need for packing/obfuscation?
I agree you are right. However everywhere I read about them they're presented as a security feature.

Okay, so long as the attacker has control over its GAC they will be able to do this. I'm accepting this answer.

How would you hack the verification code? It's signed using a 1024 bit RSA key. As to updating the references I see this is a possible way, however with a large application this becomes a very daunting task. Say if you have an application with at least a 100 assemblies and a 100k lines of code, would it even be plausible?

I've tried changing the assemblies of an application using Graywolf (digitalbodyguard.com/GrayWolf.html). However, when I try to run the application afterwards it fails because the classes are looking for assemblies signed by the original author. My modified assemblies have strong name with PublicKeyToken=null. How would an attacker overcome this?
