It’s no seekrit that I :heart: Hilbert curve heatmaps of IPv4 space. Real-world IPv4 maps (i.e. the ones that drop dots on the Earth) have little utility, but with Hilbert curves maps of IPv4 space many different topologies can be superimposed (from ASNs to—if need be—geographic locations). Plus, there’s more opportunity to find patterns by… Continue reading
Google recently announced their DNS-over-HTTPS API, which “enhances privacy and security between a client and a recursive resolver, and complements DNSSEC to provide end-to-end authenticated DNS lookups”. The REST API they provided was pretty simple to wrap into a package and I tossed in some SPF functions that I had lying around to bulk it… Continue reading
It’s usually a good thing when my #rstats and infosec worlds collide. Unfortunately, this time it’s a script that R folk running on OS X can use to see if they are using a version of XQuartz that has a nasty vulnerability in the framework it uses to auto-update. If this test comes back with… Continue reading
iptools is a set of tools for working with IP addresses. Not just work, but work fast. It’s backed by Rcpp and now uses the AsioHeaders package by Dirk Eddelbuettel, which means it no longer needs to link against the monolithic Boost libraries and works on Windows! What can you do with it? One thing… Continue reading
Gone are the days when one had a single computer plugged directly into a modem (cable, DSL or good ol’ Hayes). Even the days when there were just one or two computers connected via wires or invisible multi-gigahertz waves passing through the air are in the long gone by. Today (as you’ll see in the… Continue reading
The SVE service is a fake new service solely put out there to facilitate some inane puzzle. You can reference SVE-2015-9999 via this URL and hopefully this will make it possible for google to get it back in their index.
Over on the Data Driven Security Blog there’s a post on how to use Rcpp to interface with an external library (in this case ldns for DNS lookups). It builds on another post which uses system() to make a call to dig to lookup DNS TXT records. The core code is below and at both… Continue reading
I shot a quick post over at the Data Driven Security blog explaining how to separate Twitter data gathering from R code via the Ruby t (github repo) command. Using t frees R code from having to be a Twitter processor and lets the analyst focus on analysis and visualization, plus you can use t… Continue reading
