Automated Android APK Unpacking

Performing static analysis on an Android application can get a bit tedious when having to use apktool and dex2jar to de-compile APK files. I wanted to automate the process in an easy way to assist people with this simple but time consuming task, especially for those who want to de-compile multiple apps using both dex2jar and apktool. 

The lightweight ruby gem was built to utilize dex2jar and apktool to de-compile and output the corresponding files to a specified directory.

You can download the latest gem from here:

http://adf.ly/lcWgZ

You can view the project page on git from here:

http://adf.ly/lcWtc

Dex2jar and apktool are not included within the gem in this version so those two tools will have to be installed separately. The path of apktool.jar, dj2-dex2jar.sh or .bat, the .apk files, and output location is required to be set in a YAML file. The syntax and example of the YAML file is below but can also be found in the /examples directory of the gem:

apk:
- /Users/somebody/Desktop/com.example.apk

- /Users/somebody/Desktop/com.another.example.apk

apktool: /Users/somebody/tmp/apktool1.5.2/apktool.jar

output_directory: /Users/somebody/Desktop/apk_stuff

d2j: /Users/somebody/tmp/dex2jar-0.0.9.15/d2j-dex2jar.sh

To run the gem you execute the following commands:

apk_unpack -c <path/to/YAML file>

There are a few things we will be working on for future releases. Including the possibility of having the YAML file point at a directory instead of specific APK files, offloading de-compiling the APK files to a service running on Heroku. This would all be automated to download the APK, decompile it and then serve it to the user.

We hope you have found this post to be helpful in performing Android assessments and as usual, we'd love to hear your thoughts.

[good tool for pentester] netool.sh V4.0 just released

netool.sh is a script in bash to automate frameworks like Nmap,Driftnet,SSLstrip,
Metasploit and Ettercap MITM attacks. this script makes it easy, tasks such as
SNIFFING tcp/udp traffic, ManInTheMiddle attacks, SSLsniff, DNS spoofing, the other
modules available are:

retrieve metadata from target website, DoS attacks inside the external/local network,
also uses macchanger to decoy scans, uses nmap to search for a specified port open
in external/local lan, change/see your mac address, change my PC hostname, can also
perform TCP/UDP packets manipulation using etter.filters, also as the hability of
capture pictures of web-browser surfing on the target machine under MITM attack and
performs a vuln scan to the target web-site using websecurify firefox-addon, also
uses [msfpayload+msfencode+msfcli] to have remote control of target machine, also

Ebury SSH Rookit/Backdoor Trojan

About 3 days ago, an Ubuntu user (aka Empire-Phoenix) shouted for help at Ubuntu Forums - Security Discussions that his server has been infected by Ebury SSH Rookit/Backdoor Trojan. In his case, his mail server IP address has been blacklisted due to the infection. His story is here. (https://adf.ly/liaC4)

CERT Bund has announced the details about this rootkit/backdoor and they also include the Snort rule for the detection. The link is here. (https://adf.ly/liaLN)

The only solution is to re-install the server(s).

However, the main question is how the intruder(s) compromise our server(s) and install the rootkit? Our server(s) is/are compromised via SSH or other vulnerabilities in the server(s)?

Even if we re-install our server(s) after the infection but leave the unknown factor(s) behind, our server(s) will be infected again. If we installed IDS, we will be notified about the infection but we also need to re-install the server(s) that in question.

I supposed that the server of the captioned Ubuntu user is up-to-date and he had nothing to do with this infection as his server is a production server and he also do not know what is the problem on his server before the infection. The defensive solution is to do penetration test on the server in a regular time and it may prevent this from happening.

Well, up till now even you've realized that becoming hacker isn't that much easy! it requires lots of experience and knowledge in Software, Networking, Programming, Web Application etc. Eligibility ? Did I used any wrong word ? Let it be, there's no age limit to learn Hacking. So what is the eligibility ?

You can start learning Hacking - When you've at least 50% to 60% knowledge in Software and Web Application Programming. The second most important thing you should know Networking - At least 60%.

Why everyone recommend to learn Programming first before Hacking ?

It's simple, tell me how Software, Web Apps are made ? - Programming Languages. Almost every technology runs on Programming Language. So if you want to break (Hack) software, You must know Programming Languages. Because You're going to Hack/Crack it - Simply if you don't know Programming - So how'll you understand how it is made ? How it is working ? What's its weakness point. These questions matters! a lot.

What about Networking ? They recommend Networking too!

Almost everywhere is network! - Softwares are moving on Cloud. Cloud based technology is evolving very fast. Every Web Applications runs on Network - TCP/IP and Servers. It's highly recommended you to learn and understand how those Protocols - and technology communicates with each others on Internet. How Computer Network, Servers, Client communicates with each others.

If you're asking from where ? well even a small kid will laugh on you. Okay! There're so many resources, sites, wiki, blogs, white/black hat videos, tutorials, forums etc to learn almost everything. If you can't understand - ask for help in learning, explaining or Join any Programming/Hacking/Networking coaching. But there's no need to waste money! just with little effort you can learn in free at your home. Even we share plenty of articles, Tutorials. Join Forums, Get connected to Blogs, read Wiki's, Google each and every query you get into your mind. Read White Papers, Learn Programming from millions of sites - Search on Google. For Networking do same.

Okay Now the final & Most Important query -  How can i learn Hacking ?

This question doesn't make sense, How Can I Learn Hacking. If you're good in Programming and Networking - You can start learning Hacking. It'll be easy and understandable for you. Programming - Networking - Hacking.

We've discussed and answered some important questions, but what is the main thing in this Process ? - Whether you've Passion and Determination or Not. See even i'm learner, I understand how it feels. But never ever give-up! Be confident, Passionate, Inspired and Determined on your task.

Something About Virus!!!

What is a Computer Virus ?
A potentially damaging computer programme capable of reproducing itself causing great harm to files or other programs without permission or knowledge of the user.

Types of viruses :- 
The different types of viruses are as follows-

1) Boot Sector Virus :- Boot sector viruses infect either the master boot record of the hard disk or the floppy drive. The boot record program responsible for the booting of operating system is replaced by the virus. The virus either copies the master boot program to another part of the hard disk or overwrites it. They infect a computer when it boots up or when it accesses the infected floppy disk in the floppy drive. i.e. Once a system is infected with a boot-sector virus, any non-write-protected disk accessed by this system will become infected.

Examples of boot- sector viruses are Michelangelo and Stoned.

2) File or Program Viruses :- Some files/programs, when executed, load the virus in the memory and perform predefined functions to infect the system. They infect program files with extensions like .EXE, .COM, .BIN, .DRV and .SYS .

Some common file viruses are Sunday, Cascade.

3) Multipartite Viruses :- A multipartite virus is a computer virus that infects multiple different target platforms, and remains recursively infective in each target. It attempts to attack both the boot sector and the executable, or programs, files at the same time. When the virus attaches to the boot sector, it will in turn affect the system’s files, and when the virus attaches to the files, it will in turn infect the boot sector.
This type of virus can re-infect a system over and over again if all parts of the virus are not eradicated.

Ghostball was the first multipartite virus, discovered by Fridrik Skulason in October 1989.
Other examples are Invader, Flip, etc.

4) Stealth Viruses :- These viruses are stealthy in nature means it uses various methods for hiding themselves to avoid detection. They sometimes remove themselves from the memory temporarily to avoid detection by antivirus. They are somewhat difficult to detect. When an antivirus program tries to detect the virus, the stealth virus feeds the antivirus program a clean image of the file or boot sector.

5) Polymorphic Viruses :- Polymorphic viruses have the ability to mutate implying that they change the viral code known as the signature each time they spread or infect. Thus an antivirus program which is scanning for specific virus codes unable to detect it's presense.

6) Macro Viruses :- A macro virus is a computer virus that "infects" a Microsoft Word or similar application and causes a sequence of actions to be performed automatically when the application is started or something else triggers it. Macro viruses tend to be surprising but relatively harmless.A macro virus is often spread as an e-mail virus. Well-known examples are Concept Virus and Melissa Worm.

How to set up a web-based lightweight system monitor on Linux

Sometimes we, as a normal user or a system admin, need to know how well our system is running. Many questions related to system status can be answered by checking log files generated by active services. However, inspecting every bit of log files is not easy even for seasoned system admins. That is why they rely on monitoring software which is capable of gathering information from different sources, and reporting analysis result in easy to understand formats, such as graphs, visualization, statistics, etc.
There are many sophisticated monitoring system software such as CactiNagios, Zabbix, Munin, etc. In this article, we pick a lightweight monitoring tool called Monitorix, which is designed to monitor system resources and many well-known third-party applications on Linux/BSD servers. Optimized to run on resource-limited embedded systems, Monitorix boasts of simplicity and small memory footprint. It comes with a built-in HTTP server for web-based interface, and stores time series statistics with RRDtool which is easy to combine with any scripting language such as Perl, Python, shell script, Ruby, etc.

Main Features

Here is a list of Monitorix's main features. For a complete list, refer to the official site.
  • System load and system service demand
  • CPU/GPU temperature sensors
  • Disk temperature and health
  • Network/port traffic and netstat statistics
  • Mail statistics
  • Web server statistics (Apache, Nginx, Lighttpd)
  • MySQL load and statistics
  • Squid proxy statistics
  • NFS server/client statistics
  • Raspberry Pi sensor statistics
  • Memcached statistics

Install and Configure Monitorix on Fedora, CentOS or RHEL

First, install required packages as follows. Note that on CentOS, you need to set up EPEL and Repoforge repositories first.
$ sudo yum install rrdtool rrdtool-perl perl-libwww-perl perl-MailTools perl-MIME-Lite perl-CGI perl-DBI perl-XML-Simple perl-Config-General perl-HTTP-Server-Simple perl-IO-Socket-SSL
After this, Monitorix can be installed with this command:
$ sudo yum install monitorix
To configure Monitorix, open the configuration file in /etc/monitorix/monitorix.conf, and change the options. The details on Monitorix configuration file can be found at http://www.monitorix.org/documentation.html
By default, the built-in HTTP server listens on port 8080. Thus, make sure that your firewall does not block TCP port 8080.
To start Monitorix, simply type the following.
$ sudo service monitorix start
Start your favorite web browser, and then go to http://<host-ip-address>:8080/monitorix to access Monitorix's web interface.

Install and Configure Monitorix on Archlinux

On Archlinux, the Monitorix package can be downloaded from AUR.
By default, the built-in HTTP server is disabled on Archlinux. To enable built-in HTTP server, edit <httpd_builtin> section in /etc/monitorix.conf as follows.

        enabled = y
        host =
        port = 8080
        user = nobody
        group = nobody
        log_file = /var/log/monitorix-httpd
        hosts_deny =
        hosts_allow =
        <auth>
                enabled = n
                msg = Monitorix: Restricted access
                htpasswd = /var/lib/monitorix/htpasswd
        /auth>
/httpd_builtin>
Finally, start Monitorix service.
Open your favorite web browser, and go to http://<host-ip-address>:8080/monitorix to access Monitorix.

Install and Configure Monitorix on Debian and Ubuntu

For Debian family, Monitorix can be installed in two ways: manually or through a third party repository.

Manual installation (for Debian)

Install all dependent packages first.
$ sudo apt-get install rrdtool perl libwww-perl libmailtools-perl libmime-lite-perl librrds-perl libdbi-perl libxml-simple-perl libhttp-server-simple-perl libconfig-general-perl libio-socket-ssl-perl
Download Monitorix package from http://www.monitorix.org/downloads.html, and install it.
$ sudo dpkg -i monitorix*.deb
During installation, you might be asked to configure a backend web server. If you using Apache, make sure to reload Apache configuration by restarting Apache service.
$ sudo service apache2 reload

Installation through repositories (for Ubuntu)

Enable Izzysoft repository by appending the following line in /etc/apt/source.list.
deb http://apt.izzysoft.de/ubuntu generic universe
Download and add a GPG key for the repository.
$ wget http://apt.izzysoft.de/izzysoft.asc
$ sudo apt-key add izzysoft.asc
Install Monitorix with apt-get. All its dependent packages will automatically be installed as well.
$ sudo apt-get update
$ sudo apt-get install monitorix
Finally, start Monitorix service.
$ sudo service monitorix start
To configure Monitorix, edit /etc/monitorix/monitorix.conf with a text editor, and restart Monitorix service.
$ sudo service monitorix restart
The built-in web server of Monitorix for Ubuntu is enabled by default. To access web-based monitoring result, go to http://<host-ip-address>8080/monitorix on your favorite web browser.

Install and Configure Monitorix on Raspberry Pi

If you want to install Monitorix on Raspberry Pi (which is Debian-based), you cannot use the Izzysoft repository mentioned above because it does not provide an ARM port of Monitorix. Instead, follow Debian-based manual installation as follows.
First, install required packages.
$ sudo apt-get install rrdtool perl libwww-perl libmailtools-perl libmime-lite-perl librrds-perl libdbi-perl libxml-simple-perl libhttp-server-simple-perl libconfig-general-perl libio-socket-ssl-perl
If some of the required packages are not be installed, we need to force install with this command.
$ sudo apt-get -f install
Download Monitorix package (monitorix_x.x.x-izzy1_all.deb) from http://www.monitorix.org/downloads.html.
Install Monitorix package with the command below.
$ sudo dpkg -i monitorix_x.x.x-izzy1_all.deb
After installation is finished, we need to change a small thing in Monitorix configuration as follows.
Open /etc/monitorix/monitorix.conf with your favorite text editor. Scroll down until you find <graphs enable>. Search for "raspberrypi = n", and replace 'n' with 'y'. This will enable monitoring of Raspberry Pi clock frequency, temperatures and voltages.
After editing is done, restart Monitorix service.
$ sudo service monitorix restart
By default, Monitorix's built-in HTTP web server is enabled. To access Monitorix's web interface, go to http://<raspberrypi-ip-address>:8080/monitorix
