Cracking linux password with John the ripper – Screenshots

1.   John the Ripper is a fast password cracker for UNIX/Linux and Mac OS X.. Its primary purpose is to detect weak Unix passwords, though it supports hashes for many other platforms as well. There is an official free version, a community-enhanced version (with many contributed patches but not as much quality assurance), and an inexpensive pro version.John is different from tools like hydra. Hydra does blind bruteforcing by trying username/password combinations on a service daemon like ftp server or telnet server. John however needs the hash first. So the greater challenge for a hacker is to first get the hash that is to be cracked. Now a days hashes are more easily crackable using free rainbow tables available online. Just go to one of the sites, submit the hash and if the hash is made of a common word, then the site would show the word almost instantly. Rainbow tables basically store common words and their hashes in a large database. Larger the database, more the words covered.This post brings out screen shots showing usage of the tools with screenshots step Kali Linux

2.   In this post I am going to show you, how to use the unshadow command along with john to crack the password of users on a linux system. On linux the username/password details are stored in the following 2 files


In the screenshot below I create a user by the name of lima and create a short password for testing the tool
The unshadow command will basically combine the data of /etc/passwd and /etc/shadow to create 1 file with username and password details. Usage is quite simple as seen below :
Now this new file shall be cracked by john. For the wordlist we shall be using the password list that comes with john on kali linux. It is located at the following path

So the password cracked is "test"
A veri simple yet powerful tool as we see from the screenshots above...

1.  As recent as a week back Carbanak, an APT-style campaign targeting financial institutions has been claimed to have been discovered by the Russian/UK Cyber Crime company Kaspersky Lab who said that it had been used to steal money from banks.The malware was said to have been introduced to its targets via phishing emails and is said to have stolen over 500 million dollars, or 1BN dollars in other reports, not only from the banks but from more than a thousand private customers.The criminals were able to manipulate their access to the respective banking networks in order to steal the money in a variety of ways. In some instances, ATMs were instructed to dispense cash without having to locally interact with the terminal. Money mules would collect the money and transfer it over the SWIFT network to the criminals’ accounts.The presentation brings out the executive summary of Modus Operandi of the Malware as analysed by Kaspersky.

2.   Carbanak is a backdoor used by the attackers to compromise the victim's machine once the exploit, either in the spear phishing email or exploit kit, successfully executes its payload.Carbanak copies itself into %system32%\com with the name svchost.exe with the file attributes: system, hidden and read-only. The original file created by the exploit payload is then deleted.

How to detect CARBANAK

One of the best methods for detecting Carbanak is to look for .bin files in the

..\All users\%AppData%\Mozilla\

The malware saves files in this location that will later be sent to the C2 server when an internet connection is detected.BAT script for detecting infections(Source : here) is given as follows :

@echo off
for /f %%a in ('hostname') do set "name=%%a" echo %name%
del /f %name%.log 2> nul
if exist "c:\Documents and settings\All users\application data\
mozilla\*.bin" echo "BIN detected" >> %name%.log
if exist %SYSTEMROOT%\System32\com\svchost.exe echo "COM
detected" >> %name%.log
if exist "c:\ProgramData\mozilla\*.bin" echo "BIN2 detected"
>> %name%.log
if exist %SYSTEMROOT%\paexec* echo "Paexec detected"
>> %name%.log
if exist %SYSTEMROOT%\Syswow64\com\svchost.exe echo "COM64
detected" >> %name%.log
SC QUERY state= all | find "SERVICE_NAME" | findstr "Sys$"
if q%ERRORLEVEL% == q0 SC QUERY state= all | find
"SERVICE_NAME" | findstr "Sys$" >> %name%.log
if not exist %name%.log echo Ok > %name%.log xcopy /y %name%.log

Can we trace back device make-model from a MAC address?

Mac address of a Electronic device viz mobile/laptop are very critical for a investigating team dealing with a Cyber Incident.From an investigator point of view this one attribute associated with every device can give the Name of the OEM.I searched on net to find if the make and model of the device can be traced back via the Mac Address but couldn't find much...except for the name of the OEM I couldn't get much...for a Laptop I could get Dell and for a mobile device I could get samsung....nothing much....Is their anyway to identify and trace back the make/model??????

ANTHEM INC Data Breach : What is it all about?

1.   January 29, 2015,has gone down to record one of the greatest data breaches in the history of breaches and will be long a case study for students to learn of how it all happened.This particular breach relates to  Anthem Inc,the largest for-profit managed health care company in the Blue Cross and Blue Shield Association, that discovered that cyber attackers executed a sophisticated attack to gain unauthorized access to its IT system and obtained personal information relating to consumers who were or are currently covered by Anthem.It is believed that this suspicious activity may have occurred over a course of several weeks beginning December, 2014.

2.    Anthem disclosed that it potentially got stolen over 37.5 million records that contain personally identifiable information from its servers. According to The New York Times about 80 million company records were hacked, and there is fear that the stolen data will be used for identity theft

3.  This post brings out few key points of what ever has been discovered and revealed till now...

-   The compromised information contained names, birthdays, medical IDs, social security numbers, street addresses, e-mail addresses and employment information, including income data.

- Till now credit card ,banking information,financial,medical information  compromise has not been validated.

-   As per site...“With nearly 80 million people served by its affiliated companies including more than 37.5 million enrolled in its family of health plans, Anthem is one of the nation’s leading health benefits companies.”....shows the quantifed prone customers effected likely...and thats huge....

-   Once the attack was discovered, the company immediately made every effort to close the security vulnerability, contacted the FBI and began fully cooperating with their investigation.

-   Analysis of open source information on the cyber criminal infrastructure likely used to siphon 80 million Social Security numbers and other sensitive data from health insurance giant.

-   Less than 6 months ago a similar breach effected CHS(Community Health Systems, Inc.) of 4.5 million patient records that was attributed to “highly sophisticated malware”.

-   The Company and its forensic expert believe the attacker was an “Advanced Persistent Threat” group originating from China who used highly sophisticated malware and technology to attack the Anthem Inc Company'’s systems. 

-   According to the Associated Press, the attackers who targeted and exfiltrated more than 80 million customer records from Anthem Inc, were able to commandeer the credentials of at least five different employees.  We know from Anthem themselves that at least one admin account was compromised, as the admin himself noticed his credentials being used to query their data warehouse.


"Looking at job postings and employee LinkedIn profiles it appears that the data warehouse in use at Anthem was TeraData. By doing some quick searches on LinkedIn I was able to find more than 100 matches for TeraData in profiles of current employees at Anthem, including, CXOs, system architects and DBAs. Discovering these employees emails is trivial and would be the first step attackers could take to identify who to target for spear-phishing campaigns.

Once they are able to compromise a few high level employee systems through a phishing campaign either through malware attachments or through a browser exploit, gaining access to a user’s database credentials would be trivial. This would be where the “sophisticated malware” that is being reported would be utilized, if the malware was designed specifically for this attack it would evade most anti-virus products.

What may be a key weakness here is that it appears there were no additional authentication mechanisms in place, only a login/password or key, with administrative level access to the entire data warehouse. Anthem’s primary security sin may not have been the lack of encryption, but instead improper access controls. Although it appears the user data was not encrypted, in Anthem’s defense if the attackers had admin level credentials encryption would have been moot anyway.

I should note that TeraData provides quite a few security controls, including encryption, as well as additional data masking features, even specifically called out for protecting Social Security Numbers and related data. So odds are the actual vulnerability here is not in the software, operating system or hardware, but how the system and access controls were configured based on business and operational requirements."

Unsupported version 11 of data unit 'vga' : SOLVED

In one of my recent updates in UBUNTU 14.04 LTS,I faced an issue in the installed virtual box machines giving a message that goes as follows :

Unsupported version 11 of data unit 'vga' (instance #0, pass 0xffffffff) (VERR_SSM_UNSUPPORTED_DATA_UNIT_VERSION).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Console
Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb}

This was in-spite of the fact that I had saved my virtual machine in the manner it is supposed be and was not a power off.The machine as made to start vide the VB interface went showing the progress bar but was then followed by this above message.

How I solved this :

After working out many attempts to update and repair the Virtual Box,the simple way worked out like shown in the pic below : is as simple as choosing the machine and selecting "DISCARD SAVED STATE"
