Remote Command Exec (FireFox 2.0.0.5)

These days, i am reading about web applications hacking and trying out several different stuffs. I happen to stumble across xs-sniper's page and read about his post on owning most major browsers. It appears that there is a problem with Cross Application Browser Scripting where a flaw in the URI handling behavior allows for remote command execution. Be sure to check out his post below:

Thanks Chr1stian, Google Store flaw?

The other night i was talking to Chr1stian about XSS and google. We were chatting and suddenly the topic got more and more interesting. But anyway, Chr1stian is really a kind soul and a nice nice person to talk with. He taught me a lot of things which i don't understand and guide me slowy with each steps. Thank you Chr1stian for your patience, I can say that now i understand at least 90% of what you taught me. Also, we were talking about how security doesn't make money to flaws in google to google did not correct most of them holes that were reported by him.

I am sure that if i got a chance to test the google application, i will find more flaws, however because of my work schedule, i don't really have the time to play around. Anyway, i still wanna say thanks to Chr1stian, don't forget our deal. :)

The Web Application Hackers Handbook: Discovering and Exploiting Security Flaws

Sorry for the lack of updates. Recently, i had been reading a lot of books about web hacking and RFID and neglected blogging. Its due to work nature that i have to report what i do everyday. However, just yesterday, I had a small chat with the author of the famous burp proxy and realised that he published a book call "The Web Application Hackers Handbook: Discovering and Exploiting Security Flaws". According to him, this was what he said "Our book aims to be the most comprehensive and deep guide to hacking web applications available. It covers numerous advanced topics like blind SQL/other injection, obscure logic flaws, attacking multi-stage authentication, new attacks against webusers, ViewState tampering, decompilation of thick client components, source code review, use of bespoke automation, and many more." As usual, i would always buy books to read and this one is not to be missed. If someone can guarantee me that his book is good, with experience in developing tools and giving talks in blackhat, then i will spend that kind of money in buying his books. Well, let me know what you guys think?

Youtube's 40+ security vulnerabilities

The other night i was chatting with Chris1an about web security and i just happen to realised that he was actually the one who killed Youtube. Some of you might have already knew that he was the one who discovered around 40+ vulnerabilities in Youtube and became famous overnight. Anyway Christ1an is based in Germany and he is only a student, but hack, he is a guru in web security. He was being interviewed by the register and google actually thanked him for his work.

Recently Christ1an launched http://planet-websecurity.org/ with the intention to bring together similarly themed news and rants related to Web security and to display them in one place. Visit his blog on the right side of my feed or check it out here.

SAP

I always wanted to work for SAP because they pay huge money. I remembered i was being interviewed by SAP back in Singapore. During the first interview, it took me at least 1-2 hours of conversation and i passed the interview. The HR invited me for a second interview, however this time, the interviewer is crap. He asked all sorts of questions and i succintly answered them without beating around the bush. Its either he didnt get what i am trying to say or he is just plain talkative. I entrench strong to my roots for what i said and he did not believe me and saying that i am a pefect candidate for the position and looks like what they are searching for. ALL BLOODY CRAP!!!! A bunch of liars. They truly antagonize me and i loathe them for that. I am a straight person, if you don't wish to hire me, thats fine, just tell me straight and i will understand. Don't have to setup a bunch of stories and be a coward.

Well, good luck to you SAP. If i have a chance to audit your system, i promise i will bring down all your SAP/R3 servers and other external servers you have. Better protect your RFC or you will be OWNED!

Cisco show mem vs show processes memory sorted

For me to check the router or firewall cpu usage and the memory usage, i always issue the show mem or show processes cpu to see what is causing the router to have a high CPU or memomry utilization. However, i realised that the show mem command output is not as nice as it seemed to be. I was looking at ioshints blog and found out the same command with a little tweaks here and there. This command provides a better output than show mem which is very important for troubleshooting purposes. See below:

show processes memory sorted

show processes cpu sorted 1min

show processes cpu sorted 7min

Designing and Implementing Linux Firewalls with QoS using netfilter, iproute2, NAT and l7-filter

I was invited by Lucian to review this book. Lucian actually sent me a copy of this book for me to read and i was happy upon receiving it. Well, i am someone who loves firewall and security stuff especially linux and cisco. This book is absolutely amazing. For beginners, there are a lot of technical configuration you can read and learn and for experts, this book will guide you to some topic that might interest you. I would really want to put this book into practice, but however base on my current situation, i will only have the time to read and understand the concept. I would highly rate this book a 4.5/5 and anyone who wants to learn firewall at a low level.
