This book is a practical guide to discovering and exploiting security flaws in web applications. By “web applications” we mean those that are accessed using a web browser to communicate with a web server. We examine a wide variety of different technologies, such as databases, file systems, and web services, but only in the context in which these are employed by web applications.

Black Hat Python and black virus

In this new book, Justin covers a large range of topics that an enterprising young hacker would need to get off the ground. He includes walkthroughs of how to read and write network packets, how to sniff the network, as well as anything you might need for web application auditing and attacking. He then spends significant time diving into how to write code to address specifics with attacking Windows systems. In general, Black Hat Python is a fun read, and while it might not turn you into a super stunt hacker like myself, it can certainly get you started down the path. Remember, the difference between script kiddies and professionals is the difference between merely using other people’s tools and writing your own.

This is the first in a series of three books about computer viruses. In these volumes I want to challenge you to think in new ways about viruses, and break down false concepts and wrong ways of thinking, and go on from there to discuss the relevance of computer viruses in today’s world. These books are not a call to a witch hunt, or manuals for protecting yourself from viruses. On the contrary, they will teach you how to design viruses, deploy them, and make them better. All three volumes are full of source code for viruses, including both new and well known varieties.

Advance SQL

Same Peoples Says me that tech advance SQL Injection So Today we learn 

Advance SQL Injection 

(This is only education purpose )

What is SQL Injection attack?

SQL Injection Attacks uses SQL websites or web applications. It relies on the strategic injection of malicious code or script into existing queries. 

SQL injection is a powerful and dangerous attack. It identifies the flaws and vulnerabilities in a website or application. 

Advanced SQL 

Injection Advanced SQL injection may include an enumeration of databases like MySQL, MSSQL, MS Access, Oracle, DB2, or Postgre SQL, tables and column in order to identify privilege level of users, account information of database administrator and database structure disclosure. it also includes passwords and hashes grabbing, and transferring the database to the remote machine. 

The scope of SQL Injection Attack

 SQL injection impact can be measured by observing the following parameters that an attacker is intended to overcome: 

 Bypassing the Authentication 

 Revealing sensitive information 

 Compromised Data integrity 

 Erasing the database 

 Remote Code Execution

Types of SQL Injection Attack:

• In-band SQLi 
• Inferential SQLi
• Out-of-band SQLi 

Launch SQL Injection Attacks 

Appropriate SQL injection attack from the category cab be initiate just after gathering the information about the structure of database and vulnerabilities found. By exploiting them, the injection can be successful. SQL injection attacks such as Union SQL injection, Error-based SQL injection, Blind SQL injection and other can be used to extract information from the database such as extracting Database name, tables, columns, rows, and fields. The injection can also have intended for bypassing the authentication.

Email Security

Email Security

Everyone uses e-mail.  It is the second most used application on the internet next to your web browser.  But what you might not realize is that a significant portion of network attacks and compromises originate through e-mail. 

How E-mail Works?

We know that E-mail like as airmail is sent through the air, 'e'-mail is sent through the 'e' – the 'e' in this case being the web of electronic connections within and between the networks that make up the Internet. When you send an e-mail from your computer, the data is sent from your computer to an SMTP server. The SMTP server then searches for the correct POP3 server and sends your e-mail to that server, where it waits until your intended recipient retrieves it.
E-mail accounts are available through many different sources. You may get one through school, through your work or through your ISP. When you get an e-mail account, you will be given a two part e-mail address, in this form: username@domain.name. The first part, username identifies you on your network, differentiating you from all the other users on the network. The second part, domain.name is used to identify your specific network.

 POP and SMTP

Your incoming e-mails are going to be on a computer called a POP server. 
Your outgoing e-mails will be sent to a computer called a SMTP server. 

 Web Mail 
A second option for e-mail is to use a web based e-mail account. This will allow you to use a web browser to check your e-mail. Since the e-mail for these accounts is normally stored on the web e-mail server – not on your local computer –  it is very convenient to use these services from multiple computers. It is possible that your ISP will allow you to access your e-mail through both POP and the web. 
Safe E-mail Usage : 1

Receiving 

Everyone uses e-mail, and to the surprise of many people, your e-mail can be used against you.  E-mail should be treated as a post card, in that anyone who looks can read the contents.  You should never put anything in an ordinary e-mail that you don’t want to be read. 

• Attachment Security(Most Important )

Another real concern related to received e-mail security is attachments.  Attackers can send you malware, viruses, Trojan horses and all sorts of nasty programs.  The best defense against e-mail borne malware is to not open anything from anyone you don’t know.   Never open a file with the extension .exe or .scr, as these are extensions that will launch an executable file that may infect your computer with a virus.  For good measure, any files you receive should be saved to your hard drive and scanned with an antivirus program.  Beware of files that look like a well known file type, such as a zip file.  Sometimes attackers can disguise a file by changing the icon or hiding the file extension so you don’t know it is an executable.

• Spam, Phishing and Fraud 

Everybody likes to get e-mail. A long time ago, in a galaxy far far away it used to be you only got mail from people you knew, and it was about things you cared about. Now you get email from people you never heard of asking you to buy software, drugs, and real estate, not to mention help them get 24 million dollars out of Nigeria. This type of unsolicited advertising is called spam.  It comes as a surprise to many people that e-mail they receive can provide a lot of information to a sender, such as when the mail was opened and how many times it was read, if it was forwarded, etc.

•  HTML E-Mail 

One of the security concerns with HTML based e-mail is the use of web bugs.  Web bugs are hidden images in your e-mail that link to the senders’ web server, and can provide them with notification that you have received or opened the mail. 
Safe E-mail Usage:2

Sending

Sending mail is a little more care free.  There are some things you can do to make sure your conversation is secure though.  The first is to ensure your connection is secure (see section 9.4 Connection Security for more information). 

 Digital Certificates 

A digital certificate is unique to an individual, kind of like a drivers license or passport, and is composed of 2 parts.  These parts are a public and private key.  The certificate is unique to one person, and typically certificates are issued by a trusted Certificate Authority, or CA.

 Digital Signatures 

A digital signature is generated by your e-mail software and your private key to assure the authenticity of your e-mail.  The purpose of the signature is twofold.  The first is to certify it came from you.  This is called non-repudiation.  The second is to ensure the contents have not been altered.  This is called data integrity.

Encryption 

As an additional layer of security, you can encrypt your e-mail. Encryption will turn your e-mail text into a garbled mess of numbers and letters that can only be read by its intended recipient. Your deepest secrets and your worst poetry will be hidden from all but the most trusted eyes.  

Encryption is fairly complicated, so I’ll try to explain it in a low tech way: Jason wants to send an encrypted message.  So the first thing Jason does is go to a Certificate Authority and get a Digital Certificate.  This Certificate has two parts, a Public Key and a Private Key.  If Jason wants to receive and send encrypted messages with his friend Ali, they must first exchange Public keys. If you retrieve a public key from a Certificate Authority that you have chosen to trust, the key can be verified back to that certifying authority automatically.  That means your e-mail program will verify that the certificate is valid, and has not been revoked. If the certificate did not come from an authority you trust, or is a PGP key, then you need to verify the key fingerprint.  Typically this is done separately, by either a face to face exchange of the key or fingerprint data.

 Decryption 

So Ali has received an encrypted message from Jason.  This typically is indicated by a lock Icon on the message in her in box.  The process of decryption is handled by the e-mail software, but what goes on behind the scenes is something.

 Connection Security 
Last but not least is connection security.  For web mail, ensure you are using an SSL connection to your ISPs e-mail.  A small lock icon will appear in the bar at the bottom of your browser.  If you are using POP and an e-mail client, ensure that you have configured your email client to use SSL with POP on port 995 and SMTP on port 465.   This encrypts your mail from you to your server, as well as protecting your POP / SMTP username and password.  Your ISP should have a how-to on their web site to configure this.  If they don’t offer a secure POP / SMTP connection, change ISPs!

Advance Physical tools

Today we see same(two) advance Physical Tools to perform SE attack 

• Card Reader Cloners 

Card reader cloners were heavily covered in THP2, so I will

mainly go into updates. For the most part, HID badges that don’t require any public/private handshakes are still vulnerable to clone and brute-force ID numbers.

In THP2, we loved cloning ProxCard II badges as they don’t have any protections, can be cloned easily, and cards are generally purchased in bulk incrementally, which allow for easy brute-forcing. This was all done using the Proxmark3 device. Since then, a much more portable version of this device has been released called Proxmark3 RDV2 Kit 

More Here(Proxmark3 Kit)

This version can be configured wit a battery and is much smaller than the original Proxmark3.

Other common cards :

HID iClass (13.56 MHz)

MIFARE Classic (13.56 MHz)

HID ProxCard (125 kHz)

EM4100x (125 kHz)

• Packet Squirrel 

Another tool from Hak5 that has similar features as the LAN Turtle is the Packet Squirrel. The Packet Squirrel requires a USB micro to be powered, but instead of one end being a USB Ethernet adaptor, on the Packet Squirrel, both end are Ethernet cables. This is another discrete way to either capture traffic or create a VPN connection.

Similar to the LAN Turtle for configuring the Packet Squirrel:

Edit the /root/payloads/switch3/payload.sh

 FOR_CLIENTS=1

Edit /etc/config/firewall 

Make the exact same Firewall changes you did for the LAN Turtle

Upload the LANTurtle.ovpn file to /root/payloads/switch3/config.ovpn

Introduction to Mobile Hacking

 Mobile Hacking 

Mobile hacking makes perfect sense because of the rise of smartphone and other mobile devices for online transactions and connecting with others. Since mobile devices are hubs of personal information that are easier to access compared to personal computers, they are among the most vulnerable devices for hackers.

Most Common Question (Why should you hack mobile devices?)

• Know the location of a target through installed GPS service or cell ID tracking. 
• Get Access emails and record phone conversations 
• Know target’s internet browsing behavior 
• To View all contents stored in the device, including photos 
• Send remote instructions to the mobile device 
• Use it to send spoofed messages or calls

Mobile app hacking is among the fastest ways to infiltrate a mobile device system since it is easy to upload a malicious app online and make it possible for people to download the hack, without even thinking if they should examine their download or not. Mobile apps are also considered as “low-hanging fruit.” Most mobile apps can be directly accessed through their binary codes, or the code that mobile devices need in order to execute the app. That means that that everyone who has their hands on to marketed hacking tools are able to exploit available mobile apps and turn them into hacking tools. Once hackers are able to compromise a mobile app, they will be able to perform the initial compromise within minutes.


How hackers exploit binary codes in mobile apps?
Here Same Ways......

• Modify the code to modify behavior

When hackers modify the binary code, they do that to disable the app’s security controls, requirements for purchasing, or prompts for ads to display. 

• Inject malicious code

When hackers are able to get their hands on a binary code, they can inject a malicious code in it and then distribute it as an app update or a patch. Doing this can confuse a user into thinking that he is merely updating the app in his mobile devise, but in reality, the hacker has engineered the user into installing an entirely different app.

1.  Create a rogue app

Hackers can perform a drive-by attack, which is possible by doing an API/function hooking or swizzling. When this is done, the hacker will be able to successfully compromise the targeted application and make redirecting the traffic or stealing user credentials possible.

• Do reverse engineering

A hacker that has access to a binary code can easily perform a reverse-engineering hack to expose further vulnerabilities, do similar counterfeit apps, or even resubmit it under new branding.
