How to scan new FC LUNS and SCSI disks in Red Hat

Red Hat kullanılan sistemde multipath lun'ları taramak için uyguladığımız adımlar:

Aşağıdaki script'teki host0, host1, host2, host3 olarak belirttiğim ve tarama yaptığım aygıtlarını ihtiyacınıza göre düzenlemelisiniz. Örneğin, eğer sisteminizde host4 aygıtı bulunuyorsa bunu da eklemelisiniz.

Platform:

RHEL 6.5 x86_64

Code:

#!/bin/bash

##
# e-mail: aokany[at]gmail.com

mpathconf --disable
rm -fr /etc/multipath.conf
rm -fr /etc/multipath/bindings

service multipathd stop

libtins: packet crafting and sniffing library

libtins is a high-level, multiplatform C++ network packet sniffing and crafting library.

Its main purpose is to provide the C++ developer an easy, efficient, platform and endianness-independent way to create tools which need to send, receive and manipulate network packets.

It uses a BSD-2 license and it's hosted at github.

High level != inefficient

libtins was designed keeping efficiency in mind at all times. In fact, it is one of the fastest packet sniffing and interpretation libraries available. The benchmark section contains some actual measurements of how fast it works.

Cuckoo Sandbox

What is it? 

In three words, Cuckoo Sandbox is a malware analysis system.

In other words, you can throw any suspicious file at it and in a matter of seconds Cuckoo will provide you back some detailed results outlining what such file did when executed inside an isolated environment.

Malware is the swiss-army knife of cybercriminals and any other adversary to your corporation or organization.

In these evolving times, detecting and removing malware artifacts is not enough: it's vitally important to understand how they operate in order to understand the context, the motivations and the goals of a breach, for better protecting in the future

Cuckoo Sandbox is a free software that automated the task of analyzing any malicious file under Windows, OS X, Linux, and Android.

Volatile memory extraction utility framework

Volatility Framework - Volatile memory extraction utility framework 

The Volatility Framework is a completely open collection of tools, implemented in Python under the GNU General Public License, for the extraction of digital artifacts from volatile memory (RAM) samples. The extraction techniques are performed completely independent of the system being investigated but offer visibilty into the runtime state of the system. The framework is intended to introduce people to the techniques and complexities associated with extracting digital artifacts from volatile memory samples and provide a platform for further work into this exciting area of research.

Capture Live RAM



Belkasoft Live RAM Capturer is a tiny free forensic tool that allows to reliably extract the entire contents of computer’s volatile memory – even if protected by an active anti-debugging or anti-dumping system. Separate 32-bit and 64-bit builds are available in order to minimize the tool’s footprint as much as possible. Memory dumps captured with Belkasoft Live RAM Capturer can be analyzed with Live RAM Analysis in Belkasoft Evidence Center. Belkasoft Live RAM Capturer is compatible with all versions and editions of Windows including XP, Vista, Windows 7, 8 and 10, 2003 and 2008 Server.


Why Memory Dump Is the First Thing To Do During the Acquisition

Memory dumps are a valuable source of ephemeral evidence and volatile information. Memory dumps may contain passwords to encrypted volumes (TrueCrypt, BitLocker, PGP Disk), account login credentials for many webmail and social network services such as Gmail, Yahoo Mail, Hotmail; Facebook, Twitter, Google Plus; file sharing services such as Dropbox, Flickr, SkyDrive, etc.
