Sometimes we do require a training, may it be you know it or have seen it before. BackDoors starting from Tini/nc/Back Orifice is where we landed today. Was very interesting and kinda astonished as well how well these guys think about it! Creativity and Insanity has a very thin line between and that can be seen throughout... ... Continue Reading

DNS poisoning & XSS scripting was the hit today... Otherwise all the usual password cracking stuff which is old and quite old as well. Did like the Netcat 'chat' :-) ... Continue Reading

Today was the most impressive for the training :-) I loved the theory and the tools that lets us do Arp Spoofing, TCP Session Hijacking and IP Spoofing... Was very effective and really enjoyed doing that. It is inevitable that you put yourselves in a cracker's shoes to understand exactly what would he try or get into and the methods... One of the basics I understood today was for every attack, a strong Layer2 hack is required or rather more effective if one has it! So for the hacker /  cracker, the lower the OSI layer, the effective the attack... ... Continue Reading

Today we had some pretty appealing sessions - Google Hacking (Don't go by the name, it is not about *how to hack google*, it is about how guys can misuse the information derived from google search). As a matter of fact, till today I wasn't aware of the special search ... Continue Reading

I created this document for somebody else; thought it would be good if I share with all as well; {10 Minute Configuration of Juniper Firewalls} ... Continue Reading

So yesterday I had written about how routing takes place within the host, So lets see a weird practical example; So on a network (same network), we have 2 hosts like this; HostA(10.10.10.1/255.255.255.0)---------------------HostB(10.10.10.2/255.255.0.0) So by netmask obviously HostA is in a different network than HostB - No question about it! Now, without having a ... Continue Reading

SANS 504 - Hacker Techniques, Exploits and Incident Handling... After around 3 years I am back into a *training* :-) Today was the first day! Nothing much interesting in today's session, since it is all the same; Preached over years.... I believe it is going to be more fun from tommorrow... ... Continue Reading

So what is a Vlan ? Vlan logically separates ports in a switch to give us different networks. So for a machine in Vlan A to communicate to Vlan B, there needs to be a routing eliment - Ah, everybody knows that. Okay, good enough... So if we notice, every vlan is on ... Continue Reading

So on a network segment, how does a networked computer decide on it has to send the traffic to the default router? - A typical question for starters in Interview. Then the guys would go like, the host A has x.x.x.x ip address and it needs to talk to y.y.y.y address, ... Continue Reading

My career as Network Admin / Security Analyst was short about an year and I still remember how the users give up their passwords when asked. I used to work for a company based in US, sitting in India (remotely since I was stuck with my Visa stamping). So whenever someone ... Continue Reading
