Social Media Forensics- EC-Council Hackway Workshop Presentation

This Presentation involves with Social Media Forensics such as Email Tracing and investigation the Fraud, Scam… etc.. In the next section we covered the Twitter, Facebook, and Linkdin Forensics practically. After the video call and Instant Messaging tools, Skype is chosen because it is one of the top most popular chatting, voice/video calls (free and commercial plans). We demonstrated practically how to extract the chat conversation, contacts, call logs and much more information. Malware distribution is quite common is social media by social engineering techniques. We performed the analysis to how analysis and investigate the malware and social media investigation with malware distribution and social engineering perspective.

 

Windows warning, Question about “Your computer is correctly configured, but the device or resource (DNS Server) Is not responding”

Updating windows 8 and right after restarting, the DNS Server problem raised up out of no where

Today why the sun was shining ;), and everything was fine, my laptop notified me that, hey, you need you to update your windows. Alright, let’s do it to enjoy new security patches and fixes that Microsoft usually provides for us, :D right after updating and restarting, I couldn’t get access to the internet anymore. I could ping, but no application could access to the internet. Hey Mr Trouble (windows) I updated you to fix your problem, not to create new problems. I checked the firewall, Antivirus, and malware scanners. Everything was fine. Here are the steps I have gone through to solve the problem.

 

Restarting the Router:

Sorry, I am not the network administrator, so I don’t have any physical access to restart the university network. I couldn’t go for it, so let’s try the rest of option that I could try to solve it. Obviously I couldn’t restart the router to the default setting.

 

Renew IP addresses

I tried the “ipconfig/release” and ipconfig/renew commands, but it didn’t work

 

Restarting the DNS and DHCP services

Let’s try services.msc  (just type it in your Run), I just checked  if DNS and DHCP services are not stopped  for any unexpected reason. Both of their status were running, although I restart it. (This is windows, always restart is the first option). Nothing happened.

 

Should I Flush the DNS?

Hey Sina lets flush the DNS maybe it worked. I ran the “ipconfig/flushdns” and then “ipconfig/registerdns”.

Did it work? Hell nooo.

 

Open DNS or Google DNS

Alright buddy let’s try googleDNS/openDNS

Google DNS
8.8.8.8
8.8.4.4

Open DNS
208.67.222.222
208.67.220.220

 

It worked yeaaaaa  \m/.

Hey Mr Microsoft, this is why people prefer to go for Linux/Mac. You wanted to fix some issues; you made some new issues for me today. Although, Dear Linux has her own complicated problems, still I prefer Ms. Linux J

 

How to increase the VMware VIrtual Machine Hard Disk, and OS Hard Disk within the Virtual Machine

Many of the time we create a VMware virtual machine with a small amount of (e.g. 6 GB) for Virtual Disk. After a while, we face “low disk space” error. I had such problem few days ago.  After a bit digging google, I find out how to expand the Virtual Disk capacity. To do this, first, you need to turn off the virtual machine, and then make sure there is no snapshot, or cloned or linked VM. Then just follow as follow.

Then, as the following image you can increase the Virtual Hard Disk as much as you like.

 Chose the maximum disk size as you need

So now you can increase the hard disk of the virtual machine Operating System as well. Let’s assume that, the VM operating system is windows XP. Just download the Gparted.iso. This tool works with any Linux, Mac and Windows machines. After downloading the Gparted.iso, boot the VM with it. Just leave all the questions as default until you get the main page. You can increase the size in the gparted very easily.

The last picture shows how to increase the OS hard disk size.

Basic Android OS security mechanism,

Basic malware definition

Attacking Android platform with

Malware, Remote access, File is stealing and Social Engeering attack is methods have been done discussing in the class.

Attacking the Android:

Installing Kali Linux on android to perform attacks

Installing Dsploit for running attack with android (MITM, XSS, traffic sniffing…. Etc.)

 

you can find the presentation on my slideshare home page as well.

 

 

 

 

Hacking ATM machine?

running Malware and getting remote access is normal, but hey , is that easy to have such easy physical access to the machine?
I think they should have some behavior control portion in the system to check if any unauthorized device has been conected to the machine, dispose it and make and alarm

I think system designer should be aware of Physical access control  security
