Online Malware Analysis Tools : Listed with links

1.   Typically analyzing malware requires a great deal of knowledge in computers and expects basic knowledge of terminal commands,configuring the tool correct and right usage of advanced tools. As seen in my last post about Cuckoo usage and configuration,it is actually complex and confusing at times,now what if one can use Cuckoo without doing anything like that..no installation,no configuration,no testing and bugging...one can directly use Cuckoo directly for a sample file analysis.As we realize the power online tools,its becomes actually easier for anyone to analyze a file’s behavior by simply uploading the file to the free on-line services for automated analysis and review the detailed and yet easy to understand report.This way not only the analyst gets a quick report and analysis but more importantly he gets a variety of reports which can be compared and analyzed further leading to expedited pace of understanding and clarity of the malware architecture and working.Here I list out my choices of best on-line file/malware analyzers that can be used for free with address and screenshots of sample usage....

In fact as you google,you will find thousands of links and websites offering free online malware analysis but one has to be careful too while submitting any file to such sites.......so happy analyzing for now.....

Cuckoo SandBox:Automatic Malware Analysis Tool

1.   Cuckoo Sandbox is a malware analysis system tool which allows you to throw any suspicious file at it and in a matter of seconds it will provide you back some detailed results outlining what such file did when executed inside an isolated environment.It is written 100% in Python, the architecture is very interesting and it is based on a virtualisation engine like Virtual box to maintain a “fresh” pc always at hand to run the malware called the client, inside this client it is run as an agent that is also written 100% in Python to monitor the different calls that the malware do to the dll’s, host that try to connect, etc.The connection between the Server and the client is done through an isolated network set up by virtual box, it is configured that way in order to avoid the propagation of the malware and to communicate effectively between the client and the server to send the analysis report, infected binaries, etc.This post ahead brings you a step by step screenshot to download and configure this excellent tool,will be good for beginners in cyber security/penetration testing to play with and see results immediately.Though from the looks of this post below,the procedure looks cumbersome and complex,but I have made attempts for a naive to understand and follow up screenshot wise,any queries still will be most welcome :

WHAT IT DOES PRECISELY?

2.   Cuckoo can produce the following types of results:

- Files being created, deleted, and downloaded by the malware during its execution

- Network traffic trace in PCAP format(as we get with wireshark and ethreal)

- Traces of win32 API calls spawned by the malware

- Memory dumps of the malware processes

- Screenshots of the Windows desktop as it happens during execution of the malware

- Full memory dumps of the machines

KINDS OF FILES FOR ANALYSIS

3.   The following kinds of files can be analysed and put for check in cuckoo :

- DLL files

- Windows executables ie .exe

- Microsoft Office docs

- URLs

- Typical PDF documents

- PHP scripts

- Anything actually!!!

More about Cuckoo at the video below and http://www.cuckoosandbox.org/

PRELIMS TO SETUP YOUR SYSTEM 

4.   Be ready with the following :

-  Linux OS as parent OS

- Virtual Box installed with Windows 7/Xp

- Adequate RAM around 4 GB in all with the parent machine.

- i3 processor and above will help u lessen wait and make u patient

5.   Python comes preinstalled with the Ubuntu Desktop,but we need some extra python libraries  as follows :

Pydeep

Sqlalchemy

Bson

DPKT

Yara

MAEC Python bindings

Jinja2

Magic

Chardet

Pymongo
tcpdump
mongodb

Volatility

Libvirt

Bottlepy

Django

Pefile

Step 1

Firstly we will install all the above mentioned libraries vide a single command.You need to slect the below text and paste as it is in the terminal

    | sudo apt-get install mongodb python-sqlalchemy python-bson python-dpkt python-jinja2 python-magic python-pymongo python-gridfs python-libvirt python-bottle python-pefile python-chardet tcpdump -y

Besides above,there are other python libraries that need PIP for installation.Pip is an alternative to Easy Install for installing Python packages and is largely recommended when used in virtual environments.

|   sudo apt-get install python-pip python-dev libxml2-dev libxslt-dev
|   sudo pip install django cybox 
|   sudo pip install MAEC

another important library tcpdump is required to be configured to allow Cuckoo to make use of it without requiring root.

|  sudo setcap cap_net_raw,cap_net_admin=eip /usr/sbin/tcpdump 

Two additional software Yara and Pydeep too need to be installed and the cuckoo documentation states these need to be installed separately, however Yara is provided in the Ubuntu universe repository. but before installing Pydeep , we need to install some dependencies with the following command line to install the following :

Build-essential
Git
Libpcre3
Libpcre3-dev
Libpcre++-dev

sudo apt-get install build-essential git libpcre3 libpcre3-dev libpcre++-dev

Cuckoo requires Yara 1.7 or higher and to install yara,run the following command

sudo apt-get install yara -y

Pydeep depends on ssdeep 2.8+ and ssdeep needs to be compiled from source and likewise for Pydeep. Before doing so, a few packages are needed. The following commands will work :

|   sudo apt-get install build-essential git python-dev -y
|   wget http://sourceforge.net/projects/ssdeep/files/ssdeep-2.12/ssdeep-2.12.tar.gz/download -O ssdeep.tar.gz
|   tar -xf ssdeep.tar.gz
|   cd ssdeep-2.12
|   ./configure
|   make
|   sudo make install
|   ssdeep -V
|   2.12(output for above)

We also need to install “git’:

sudo apt-get install git

Now cd to the directory Download, clone the pydeep project and install manually:

git clone https://github.com/kbandla/pydeep.git

cd pydeep

sudo python setup.py install

Install Yara

sudo apt-get install libtool automake

Then download yara form the git repository and install it:

cd && cd Downloads

wget https://github.com/plusvic/yara/archive/2.1.0.tar.gz

tar -xvzf 2.1.0.tar.gz

cd yara-2.1.0

chmod a+x build.sh

./build.sh

sudo make install

Now we need to install yara-python with the following commands:

cd yara-python

sudo python setup.py install

Volatility supports memory dumps from all major 32- and 64-bit Windows versions and service packs including XP, 2003 Server, Vista, Server 2008, Server 2008 R2, Seven, 8, 8.1, Server 2012, and 2012 R2 but in recent past now on supports Linux memory dumps in raw or LiME format and include 35+ plugins for analyzing 32- and 64-bit Linux kernels from 2.6.11 - 3.16 and distributions such as Debian, Ubuntu, OpenSuSE, Fedora, CentOS, and Mandrake.VOLATILITY is to be installed next,we need the following commands:

cd && cd Download

wget wget http://volatility.googlecode.com/files/volatility-2.3.1.zip

Once u download this, extract it and install it:

unzip volatility-2.3.1.zip

cd volatility-2.3.1

sudo python setup.py install

Installation time now for  Cuckoo

First we need to clone the git directory wherever we want to install Cuckoo, and we install it in /opt directory with the following commands:

cd /opt

sudo git clone https://github.com/cuckoobox/cuckoo.git

sudo chown -R user:usergroup cuckoo

Where user:usergroup is the user used to login to the ubuntu machine and the group is the group to which user belong

Now we shift our attention to configuring networks for Virtual Box and parent machine.So I assume you have installed Windows 7 in virtual box with Adobe,Microsoft Office and a Mozilla/Chrome browser.

 Configure as shown next below :

Vide the above,the two IP addresses I have configured to ping are :

Parent/Host OS : 192.168.56.1
Virtual Windows Machine : 192.168.56.101

Just ping from each IP to other,if they ping all is set now to work ahead.

and one important step that remains is to configure the conf files in the cuckoo configuration,Few important configuration files that we effect to work with are mentioned below with brief functionality:

cuckoo.conf : This configuration file contains information about the general behavior and analysis options in Cuckoo Sandbox.
machinemanager.conf : This file holds the information about your virtual
machine configuration: Depends on the name of virtualization that we used.
processing.conf : This file is used for enabling/configuring the processing of modules.
reporting.conf : This file contains information about reporting methodologies.

There are a few things required to be changed in the configuration files as follows:
[I used gedit to edit and make amends to these conf files]

/opt/cuckoo/conf/cuckoo.conf

[cuckoo]

memory_dump = on

[resultserver]

ip = [ip address of the vboxnet0 interface, to check it issue on terminal ifconfig vboxnet0, usually 192.168.56.1]

/opt/cuckoo/conf/virtualbox.conf

[cuckoo1]

label = [Name of the Windows guest virtual machine as configured on VirtualBox]

ip = [ip address configured i the windows guest]

snapshot = [the name of the snapshot taken with virtual box]

/opt/cuckoo/conf/memory.conf 

[basic]

delete_memdump = yes

/opt/cuckoo/conf/processing.conf 

[memory]

enabled = yes

[virustotal]

enabled = yes

key = [key of the virus total API, could be obtained registering in http://www.virustotal.com

/opt/cuckoo/conf/reporting.conf 

[maec40]

enabled = yes

[mongodb]

enabled = yes

Now we can run Cuckoo after all the hardwork :

run the command as shown below  and you should get the screen as below :

sudo python /opt/cuckoo/cuckoo.py

Now we need to do a submission of a file vide a script as shown below :

python /opt/cuckoo/utils/submit.py —package PACKAGE PATH_TO_FILE

or as I type for my screen shot command :

python /opt/cuckoo/utils/submit.py /home/cuckoo/Desktop/cuccccck/shared/malware.pdf

or there is a way for a web interface too :

cd /opt/cuckoo/utils and then run ./web.py as shown below :

Now you r ready to analyse with the Cuckoo installed....next post will focus on analyzing the files with Cuckoo...........

vCard Vulnerability : WhatsApp

1.     WhatsApp,the exceedingly renowned application that has actually swung around the way we all chat, talk, share and do so many things has so many PROs but over this small period of time since its inception it has also been the quarry of cyber criminals. With a user base as strong as 900 million active users in Apr 2015,any vulnerability in the architecture cosmos is destined to be a remunerative lure for any cyber criminal. A recent vulnerability in the form of simply sharing a vCard with other user discovered by Check Point security researcher Kasif Dekel has come to the fore. It involves simply sharing the seemingly guileless vCard with the victim and as the victim clicks the vCard, his task his over since rest will be done in the background by the malicious code terra incognita to the user. This vCard actually exists as an executable file and gets into action the moment it gets clicked by the user in the application. 

 

 

RESOLVED by update from WhatsApp 

2.   WhatsApp affirmed and recognized the security egress and have released the fix in all versions greater than 0.1.4481 and blockaded that especial lineament. 

How it Happens? 

3.   To activate the code, Kasif Dekel ascertained an attacker could just inject the command to the name attribute of the vCard file, separated by the ‘&’ character. When executed, it will attempt to run all lines in the files, including controlled injection line. Once such a contact is made, all an attacker has to do is share it via the normal WhatsApp client. 

What made the application Vulnerable? 

4.    WhatsApp Web allows users to view any type of media or attachment that can be sent or viewed by the mobile platform/application. This includes images, videos, audio files, locations and contact cards.Thus the default action runs for the vCard for running the code whilst being understood as sharing the contact details. 

 

What can it do ?

 

Once the code is activated,it is bound to take complete control over the target machine and will definitely monitor the user’s activities and use the target machine to spread malicious malwares and viruses ahead.

Timelines by CHECKPOINT on the vulnerability 

 
    August 21, 2015 – Vulnerability disclosed to the WhatsApp security team.
    August 23, 2015 – First response received.
    August 27, 2015 – WhatsApp rolls out fixed web clients (v0.1.4481)
    September 8, 2015 – Public disclosure 

Thanks CHECKPOINT

Green Computing and Security Aspects

Green computing is a buzzing word in the IT sector in past few years for a  substantially serious reason that abridges with futurity that may turn to be a perturbing factor for the succeeding generations if not planned and given due concern today. Given the quantity of indisputable E-waste being generated across globe, the concern is actually flagitious. Any reader amply clear on green computing may not be able to relate of what Information security domain has got to do with green computing, but alas there is a connect as I decipher ahead in this article which got published in CSI Communications journal by Computer Society of India in this months issue.The link to the article is http://www.csi-india.org/communications/CSI%20Aug.%2015%20Combine.pdf

Whatsapp Chat History : How to avoid chat backing up?

1.    WhatsApp has been one of the revolutionary social networking application on the lines of various past hits like Facebook,one time orkut etc and today has a huge user base in billions exchanging all kinds of official,unofficial,personal chat kind of communications.Off course keeping a backup of all these chats is sometimes essential and in few cases for whatever reasons of the user base it is not required....the users wanna refrain from backing up anywhere any kind of history..no tell tale signs to be recovered...Although I have seen people ensuring themselves deleting the chat as it happens but that’s not a technically sound way to ensure nothing is being backed up

2.   For those who want to ensure a back up ...Daily at 0400 am the Whatsapp Auto backup is taken by the app itself so no need to worry for this and if you switch off or activate flight mode at night then one might need to take manual backup.For those who do not want any backup , a simple procedure as shown below will ensure a blank backup.

3.   Goto your Android application screen and search for MyFiles :

Choose the location where you have the default whatsapp files..in my case the default saving location is internal sd card.Click this and you look for the Whatsapp folder.

Further go inside Whatsapp folder and look for Databases....delete every thing inside this before 0400 cycle comes again.That should work....here the 0400 cycle backups the entire thing but defacto there is nothing to upload and backup.
