Attack Log Analysis with Scalp! Description: Scalp is a very great apache log attacker analyzer using php-ids IDS pattern file. If you scan your web site logs weekly or daily, you will see attacks are coming to your site on a regular basis. People tend to check their logs only after compromise is accomplished. It is too late. Attackers have 0wned their sites and manipulated log files! Date: Sept 2008

HTTP Form Brute Forcing With JHijack Description: The Initial reason for JHijack is to use it in numeric Session Hijacking but its uses depend only on who use it. We've given yet another example in Blind SQL Injection. This time, it can also be used as HTTP Form Cracker like an old school - Brutus. Date: Nov 2008

Why JS Malwares are still prevelent and bypassing AV Scanners Description: Even up to now due to today's AV Scanner's Poor Defense against web worms, we'll never be secure. This movie shows you how JS malwares can easily bypass AV Scanners using stupid string manipulation techniques. Date: May 2009

Session Strength Analysis With Stompy Description: Stompy performs NIST FIPS statistical tests on session generation and checks for correlations between arbitrary bits. A truly random token never exhibits correlation between the stage of one bit and the state of another. In this movie, I'll show you how to download, extract, compile, and run Stompy and analyze session tests for failure or pass. Ref: WAHH . Size: 10 MB Date: May 2008

Ref: WAHH . Size: 2.05 MB Date: May 2008

Discovering Browser Plugin Vulnerabilities Description: See how attacker find flaws in web browser plugins to install malware to your computer. For example, if a plugin has vulnerable readFile/loadFile function, then he can read/load any files from your computer and then send them to his sever. Similarly, for saveFile function, he can overwrite any files on your disk with malicious content. Size: 9.38 MB Date: May 2008

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 .

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. Size: 3.51 MB Date: March 2008

Desirable Input Validation Baseline Check Description: This demonstration shows you on how you should implement baseline acceptable input filtering on visitors' inputs. Filtering inputs are the most important because 100% injection attacks (XSS,SQL,XPATH,OS CMD ...etc) come from inputs where filtering is weak or none. Developers should always be aware of inputs as well as outputs! You know Garbage In Garbage Out but for attackers, Garbage In Gold Out! Size: 4.09 MB Date: Jan 15, 2008

Download Web Application Security Papers Archived (WASPA) This project is a collection of web application security related documents, presentations, cheetsheets, guides and the like. As for always, those resources are scattered among thousands of resources on the web. Some are really worth to read but are sadly unknown by a whole large. The only noble aim of Security students, professionals, or researchers is to bring reliable security and countermeasures to our next-generation IT communication. I attempt to support this aim by collecting resources altogether in one place which can be downloaded by those who're eager for stronger security. Started: June 2008

To generate assessment report, the following famous two methodologies are used as framework or checklists. Practical skills on tools and knowledge are required to perform the assessments accurately according to defined methodology. Carrying out assessments that satisfy all tasks mentioned in these methodologies ensures reasonable level of security. They provide pentesters baseline checklists so as not to miss anything. For more information, please buy "Web Application Hacker's Handbook" for Portwigger and download OWASP Testing Guide from owasp.org . If you'd like to propose hybrid methodologies combined with your own experience, don't hesitate to contact us. Over time, these methodologies need to be updated to cope with evolving attack vectors and threats.
