Password Based Attack (THC Hydra)

Password is a secret word that is used for authentication or proves your identity, password is a foundation of security for most computer or computer networks. Usually a normal user do not know the importance of password, many users choose the simplest
password such as a pet’s name to help them remember it.

Nowadays, many services use cryptography technique to secure their information, cryptography is the art of secret communication, by using cryptography techniques you can secure your password and make your password difficult to crack.

his is an old but simplest method that an attacker used to crack passwords, as i told earlier that a normal user do not know the importance of password and a normal user do not care about passwords, many of the people use very weak passwords such as their pet’s name, lover name, friend or relative, phone numbers or passport numbers etc.
If your password is so weak than an attacker who knows you personally can easily guess your password, so be careful while choosing your passwords. If an attacker does not you personally so he/she uses some of social engineering technique to get your personal information.

Dictionary Based Attack
Dictionary attack happen when an attacker create a wordlist(a dictionary) which contains some commonly used passwords, name of places, common names, and other commonly used words. To avoid this type of attack you must choose a strong password.
There is various password cracking tools present on the internet like:

. cain & able
● John the Ripper
● THC hydra
● Aircrack (WEP/WPA cracking tool)
● L0phtcrack
● Brutus
● Or more.

OWASP Top 10 Tools and Tactics

A tool for each of the OWASP Top 10 to aid in discovering and remediating each of the Top Ten vulnerabilities!

Introduction: If you’ve spent any time defending web applications as a security analyst, or perhaps as a developer seeking to adhere to SDLC practices, you have likely utilized or referenced the OWASP Top 10. Intended first as an awareness mechanism, the Top 10 covers the most critical web application security flaws via consensus reached by a global consortium of application security experts. The OWASP Top 10 promotes managing risk via an application risk management program, in addition to awareness training, application testing, and remediation. Yet, to manage such risk as an application security practitioner or developer, an appropriate tool kit is necessary.

RISK TOOL
A1: Injection ……………………………………………………. sQL Inject Me
A2: Cross-Site Scripting (XSS)……………………………… ZAP
A3: Broken Authentication and Session Management. HackBar
A4: Insecure Direct Object References ………………….. Burp
A5: Cross-Site Request Forgery (CSRF) …………………. Tamper Data
A6: Security Misconfiguration …………………………….. Watobo
A7: Insecure Cryptographic Storage…………………….. N/A
A8: Failure to Restrict URL Access……………………….. Nikto/Wikto
A9: Insufficient Transport Layer Protection…………… Calomel
A10: Unvalidated Redirects and Forwards……………… Watcher

How Antivirus Software identifies threats!

Most of us are aware how Antivirus Works and updates. As ever increasing threat from virus and other malicious programs, almost every computer today comes with a pre-installed antivirus software on it. In fact, an antivirus has become one of the most essential software package for every computer. Even though every one of us have an antivirus software installed on our computers, only a few really bother to understand how it actually works and updates.

An antivirus software typically uses a variety of strategies in detecting and removing viruses, worms and other malware programs.

Signature-based detection – Dictionary based
Heuristic-based detection – Suspicious behavior based
1. Signature-based detection – Dictionary based

This is the most commonly employed method which involves searching for known patterns of virus within a given file. Every antivirus software will have a dictionary of sample malware codes called signatures in it’s database. Whenever a file is examined, the antivirus refers to the dictionary of sample codes present within it’s database and compares the same with the current file. If the piece of code within the file matches with the one in it’s dictionary then it is flagged and proper action is taken immediately so as to stop the virus from further replicating. The antivirus may choose to repair the file, quarantine or delete it permanently based on it’s potential risk.

As new viruses and malwares are created and released every day, this method of detection cannot defend against new malwares unless their samples are collected and signatures are released by the antivirus software company. Some companies may also encourage the users to upload new viruses or variants, so that the virus can be analyzed and the signature can be added to the dictionary.
More and regular the updates more secure we are.

2. Heuristic-based detection Suspicious behavior based
Heuristic-based detection involves identifying suspicious behavior from any given program which might indicate a potential risk. This approach is used by some of the sophisticated antivirus software’s to identify new malware and variants of known malware. Unlike the signature based approach, here the antivirus doesn’t attempt to identify known viruses, but instead monitors the behavior of all programs.

File emulation- This is another type of heuristic-based approach where a given program is executed in a virtual environment and the actions performed by it are logged. Based on the actions logged, the antivirus software can determine if the program is malicious or not and carry out necessary actions in order to clean the infection.

ow to check your anti virus weather it does the work you haired it for?

European Institute of Computer Antivirus Research – EICAR Test makes it easy. It is a common test and most of us can perform it right now!
1. Open a notepad (New Text Document.TXT) and copy the following code exactly onto it, and save the notepad.
EICAR Test Code:

1 X5O!P%@AP[4PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
2. Rename the file from New Text Document.TXT to mynewfile.com
3. Now run the antivirus scan on this mynewfile.com file.

If the antivirus is functioning properly on your computer, then it should generate a warning and immediately delete the file upon scanning. Otherwise find a new one.

DOMXSS Scanner: An Online Tool to find Potential DOM Based XSS Vulnerabilities!

DOMXSS Scanner is an online tool that helps you find potential DOM based XSS security vulnerabilities. Enter a URL to scan the document and the included scripts for DOMXSS sources and sinks in the source code of Web pages and JavaScript files.

What is DOM Based XSS?
“DOM Based XSS (or as it is called in some texts, “type-0 XSS”) is an XSS attack wherein the attack payload is executed as a result of modifying the DOM “environment” in the victim’s browser used by the original client side script, so that the client side code runs in an “unexpected” manner. That is, the page itself (the HTTP response that is) does not change, but the client side code contained in the page executes differently due to the malicious modifications that have occurred in the DOM environment.”

DOMXSS Scanner is what we would like to call a cloud-based web security scanner. It can be considered as a next generation scanner not exactly in performance and report wise but in community edition web security.

BufferZone Pro as a Freeware!

Recently, Trustware gave away free license keys of the Pro version of BufferZone and now the company has decided to make it completely FREE! BufferZone Pro is security software which creates a virtual environment aka “Virtual Zone”, where users can run browsers or other applications in a completely isolated mode, so in case of a malware infection the applications running inside the “Virtual Zone” will not damage the real system. BufferZone Pro can run alongside a antivirus, firewall, or internet security suite and is compatible with 32-bit OS only.

We find it very useful while testing web based malwares.
Key Features of BufferZone Pro:

Safely download anything in an isolated (virtualized) zone
Safely browse in an isolated zone
Safely chat with IM in an isolated zone
Schedule periodic “flushes” of the Virtual zone
Safely share with P2P applications in an isolated zone
Safely use USB devices in an isolated zone
Lock your personal files (in confidential folders) inside a trusted zone
Take a “snapshot” of the Virtual Zone for one- step restore
It is compatible with 32-bit version of Windows XP, Windows Vista and Windows 7.
