How does your DNS resolver know how to find the DNS server responsible for resolving your DNS address? Why DNS of course. Pretty simple actually, the DNS client asks the DNS resolver for the address the resolver asks its own DNS resolver who asks the DNS server who to ask
One of the benefits we saw for using DNS in Part 1 was the ability to bounce our traffic through different systems that we don't control. Up until now we have been going directly to the DNS server we control. When your host computers doesn't know
Now that our client has the ability to read arbitrary data from the server, lets update the client to be able it to send arbitrary data to the sever. (Psssst, if you are new start with Part1) The problem As we learned in Part4 DNS can only transfer very small
Hello again friends. This is exciting we are starting to actually get somewhere.... Let's get after it, first a quick recap. Remember we are building a key/value store with DNS as our communication mechanism to explore how hackers get data out of networks. Part 1 was an
Okay I kind of just had my mind blown. I am working on an interesting project in which I need to modify a PE file. The problem with modifying PE files is there is a checksum that windows defender looks at and flags you as being a mean bad jerk
Now that we have a server, it is time to build the client. In Part 2 we laid out the ground work of our project and built a server that could respond to various DNS queries (check out Part 1 if that is gobbledygook). As usual you can jump right
As we continue to explore how hackers take advantage of DNS, our goal for part 2 is to get into some rust code and build a server that has enough functionality that it will be able to respond to simple DNS requests. If you missed it, check out Part 1
DNS is one of the protocols that make the internet possible. In many ways DNS is the phone book of the internet. DNS turns the domain you are trying to get to into the IP address your computer needs to get there. DNS is robust network of inter connected systems
In infosec, being able to explore and manipulate data is a super power. After years (decades) of using python, these are some of the things I lean on almost every day to make the hax and explore. Python is an amazing programming language. Python is simple, concise and flexible. It
