The YEHG was established in Jan 2008 by a small group of young but mature people. The initiatives broke out in the hope of united force that can beat any obstacles and accomplish any goals we desire. We are NOT BLACK Hats. We are not concerned with or employed by Myanmar Government or any organizations.

Mission

To become one of the best, respectable, powerful groups in the world who’re ever dedicating their lives in ethical hacking and countermeasures.

Objectives

1. To share each other in learning new skills, researches and developments
2. To help each other’s desired goal all together

We provide the following security services and trainings at a reasonable charge:

• Services:
  • Linux System Administration
  • VPS Security Configuration & Management
  • Hardware Appliance Development
  • Web Appication: Whitebox Testing via Source Code Auditing
  • Web Application: Blackbox Testing via Full Penetration Testing
• Training:
  • Practical Network Hacking
  • Web Appication Attacks & Defenses

As for web application security reports which are based on PortSwigger and OWASP methodologies, we provide you with assessment reports like HTML & PDF.

Our papers and articles are not hacker-only-readable.
We made them pretty short and simple but informative and effective for every IT professional. We don't use big jargons.

Privacy Policy: No data is sent to our server. We don't even implement update check on our tools, which may collect your IP information. Some guys in the wild have said that our tools send your pentesting results to us. They say without even actually knowing how to view source codes. We host our tools only at trusted opensource hosting sites - sourceforge.net and googe code base. Each tool has its own weakness and strength in various situations. It's your responsibility and smartness to make the best use of tools.

In fact there are hundreds of tools out there. We don't even need to create our own; don't need to re-invent the wheels. We only want to do what hasn't still existed on the web. The following ones are what we have to develop after web searches return none.

• Web Firewall Stress Tester
  Description: A tool to be used for newly created OSS web firewall/proxy/servers 'coz I found vulnerability in this way. Submit (GET/POST/HEAD) user-defined packets to web firewall to test its security strength. Tell you at which packet length a firewall will crash. Good for Heap/buffer overflow hunting.
  [REQUEST] <----> | Web Firewall | <----> [WebServer]

  Requirements: Perl

  Date: Nov 2008

  
  
• Web Firewall Detector
  Description: Typical Web Firewalls use a mechanism to classify anomaly traffics. This tool submits an old-school malicious (not dangerous) request, and tells you the type of firewall a particular web site use (if any). Mainly useful for blackbox security assessment. Coded years ago. Ref: Web Hacking Exposed 2nd Edition, ISBN:9780072262995

We don't intentionally hunt for vulnerabilities. The following ones are some of what we came across. [more...]Surely enough, we are not the only ones who found such holes. Many security professionals may have found the same holes at the same time or so. According to hacker code of ethics, we never do any harm or damage to our tested target (Yes, to do damage is one further step that exploits found weakenesses). and make disclosure only after vendor has been reported. But some vendors don't even response;hence we assume that they ignore our reports. There is no patch for ignorance.

We always find it difficult to explain security-knowlege-lack-and-stubborn-to-fix developers about security risks, threats and vulnerabilities. There are always many common myths of security which provoke Today secure and Tomorrow hacked. That's why we can't tell you something like “ Hey, guy  This is a protection code - Use this and your life will be forever secure! ” Here, we feature high-risk vulnerabilities info about web applications. The numerous number of vulnerablities in today's web sites are featured in our WSSAd project.

This is our ongoing project to maintain the most live ever-updated comprehensive links repository. We take pains to make the HWD sure for quality links resources. Click the logo below to enter into hwd:

We recently migrated our files to sourceforge.net.Some older files can be available via our older first mirror. Our videos illustrations of various networking/hacking/security processes and tools were tested on our hacking lab environments and intended only for security hardening purpose. Please don't complain if those don't work for you. Watch and forget'em! Off and on, fearless security professionals have ended their careers due to penetration testing computer systems (they don't own) without permission. Only use your hacking skills in ethical and lawful purposes! Know the meaning and essence of ethical hacking!

Requirement: No more than a web browser with Flash player plugin.

• Owning the box via Web Browser Flaw
  Description: You'll never think of how dangerous a link you've clicked! Generally exploiting browser vulnerabilities to gain remote access may bypass firewalls that are protecting your workstation. Firewalls typically block new, inbound connection attempts but allow users behind the firewall to create outbound connections, which allow both parties of that established connection to communicate freely in both directions over that channel. If an attacker wants to attack your firewall-protected computer, he will normally be blocked by your firewall. However, if the attacker instead hosts the domain evil.com and entices you to browse to www.evil.com, he now has a communication channel to interact with your computer. Ref: GHHB.

• Owning the box Via Web Application Flaw
  Description: See how an attacker can use our recent discovery of File-Upload vulnerability in Gmail-Lite to 0wn the entire box. This is to teach developers how a flaw in web application is evil.In this movie, you should learn: 1) Attacker bypasses Firewall by making victim machine connecting back to him via port 80 2) He bypasses WebServer level restrictions on dangerous APIs such as system, exec ...etc by using backtick operator (`) to execute any commands he wants.

• Performing Directory Brute-Force Attack
  Description: There are dozens of tools that let us brute-forcing directories names for sensitive information digging. In this movie, we illustrated Directory Brute-Forcing with the tool called 'JBroFuzz'. The reason why we like it is that it can brute force a large number of directories. As of this writing,the latest version JBroFuzz 0.8 has 58658 directories names that are commonly used by today's web sites. The only defense is you must not place/protect sensitive information in server-side (.htaccess). Just wanna show you - Security Through Obscurity is broken.
