Article: Quickpost: Decrypting Cobalt Strike Traffic - published over 3 years ago.
Content: I have been looking at several samples of Cobalt Strike beacons used in malware attacks. Although work is still ongoing, I already want to share my findings. Cobalt Strike beacons communicating over HTTP encrypt their data with AES (unless a trial version is used). I found code to decrypt/encrypt such data in the PyBeacon and Geacon Github repositories. ...

Article: Update: base64dump.py Version 0.0.14 - published over 3 years ago.
Content: This new version of base64dump.py supports a new encoding: NETBIOS Name encoding. NETBIOS Name encoding is very similar to hexadecimal encoding: in stead of hexadecimal digits 0-9 and a-f, letters A-P are used. I encountered this in DNS TXT records of a Cobalt Strike DNS stager. More on that later. base64dump_V0_0_14.zip (https)MD5: 35BF4900BED...

Article: Converting NMAP XML Files to HTML with xsltproc - published almost 4 years ago.
Content: NMAP is a wonderful network scanner and its ability to log scan data to files, specifically XML, helps quite a bit.  This enables the scan data to be parsed by other tools such as Metasploit’s db_import or even NMAP’s own Zenmap GUI.  While XML is great for parsing, it’s not really easy for humans to read.  I have found several people are unaware of the fac...

Content:     Today I want to continue the series on using LD_PRELOAD.  In previous posts, we covered how to inject a shared object binary into a process, and use that to hijack a library function call to run our own code.  This is great when we want to overwrite the behavior of external library calls in a process, but we would have to wait for that call to happen fi...

Article: Linux X86 Assembly – How to Build a Hello World Program in NASM - published over 3 years ago.
Content: Overview A processor understands bytecode instructions specific to that architecture.  We as humans use mnemonics to make building these instructions easier than remembering a bunch of binary codes.  These mnemonics are known as assembly instructions.  This is one of the lowest levels of programming that can be done.  This programming is a bit of a lost ...

Content: Seamless and unobtrusive security is the future. We are huge advocates of shifting left and moving security testing earlier in the development process. Leif Dreizler wrote a great article suggesting that not only do we need to shift security left, but shift engineering right. I agree, but why stop there. We all need to cultivate a culture of consistent coll...

Content: Overview In the last two tutorials, we built a Hello World program in NASM and GAS for x86 assembly.  While this can help us learn x86 assembly, it isn’t viable as a payload for use in exploits in its current form.  Today’s blog will look into what those issues are, how they impact the code’s use as a payload, and what we can do to address those issues. ...
