I published the following diary on isc.sans.edu: “Malicious Python Script Behaving Like a Rubber Ducky“: Last week, it was SANSFIRE in Washington where I presented a SANS@Night talk about malicious Python scripts in Windows environment. I’m still looking for more fresh meat and, yesterday, I found another interesting one. Do you
I published the following diary on isc.sans.edu: “RedLine Stealer Delivered Through FTP“: Here is a piece of malicious Python script that injects a RedLine stealer into its own process.

I published the following diary on isc.sans.edu: “Malicious Python Script Targeting Chinese People“: This week I found a lot of interesting scripts as this is my fourth diary in a row! I spotted a Python script that targets Chinese people. The script has a very low VT score (2/56) (SHA256:aaec7f4829445c89237694a654a731ee5a52fae9486b1d2bce5767d1ec30c7fb).
I published the following diary on isc.sans.edu: “Python Shellcode Injection From JSON Data“: My hunting rules detected a niece piece of Python code. It’s interesting to see how the code is simple, not deeply obfuscated, and with a very low VT score: 2/56!. I see more and more malicious Python code

I published the following diary on isc.sans.edu: “Using Sudo with Python For More Security Controls“: I’m a big fan of the Sudo command. This tool, available on every UNIX flavor, allows system administrators to provide access to certain users/groups to certain commands as root or another user. This is performed with a
I published the following diary on isc.sans.edu: “Python DLL Injection Check“: They are many security tools that inject DLL into processes running on a Windows system. The classic examples are anti-virus products. They like to inject plenty of code that, combined with API hooking, implements security checks. If DLLs are
I published the following diary on isc.sans.edu: “Keeping an Eye on Dangerous Python Modules“: With Python getting more and more popular, especially on Microsoft Operating systems, it’s common to find malicious Python scripts today. I already covered some of them in previous diaries. I like this language because it is very
I published the following diary on isc.sans.edu: “From Python to .Net“: The Microsoft operating system provides the .Net framework to developers. It allows to fully interact with the OS and write powerful applications… but also malicious ones. In a previous diary, I talked about a malicious Python script that interacted with the
