Hi all, the past 19 of June i presented at OWASP VI Spain Meeting, a review of Bruteforce attacks in web applications, this is an old technique that is still useful for the attackers, and i showed with examples that is present in many attacks that affect big companies like Facebook, Yahoo, AT&T, Tuenti, etc. Also i presented the latest version of Webslayer a tool to perform all kind of bruteforce attacks in web applications.

Massive Web Application discovery with Wfuzz

Last week i had to review like 40 websites for a penetration test in a short period of time, so the first thing i wanted was to search for directories or files in the web servers, so how can i automate the full scan with Wfuzz? We can use a command like this:

$ wfuzz -c -z file -f urllist.txt,dictionary.txt --html --hc 404 http://FUZZ/FUZ2Z 2> results.html

The first FUZZ will be replaced with the content of urllist.txt, where you should have the websites address in the format "", and the second FUZ2Z will be replaced with the dictionary, in my case i used the big.txt.

Soon i will release an update of Webslayer, and will show how to do this with it.

Security Ezines 2010

Hi all, in this brief post i will like to share some new ezines about security that were relased this year, the first one is called Into the Boxes, and it's centered in Forensics and Incident response, it's a join effort from Harlan Carvey and Don (securityripcord), this ezine looks promising. You can download the first issue here.

The other ezine is the one launched by Hack In the Box (HitB), this magazine has a very professional look and a lot of articles, can be compared with a Hakin9 magazine, but free. They relaunched the ezine this year. You can download the first issue here.

It's cool to see fresh initiatives for sharing knowledge :)

I would like to see a Kindle version of them ;)
