DNS resolves are done using libudns, which is a neat non-blocking dns resolving library with support for AAAA records and chained cnames. So much about non-blocking. Protocols Network services speak a certain language, this language is called protocol.

When we started deploying honeypots, you could trap worms just by opening a single port, and wait for them to connect and send you an url where you could download a copy of the worm. The service getting attacked was the backdoor of the bagle mailworm, and it did not require and interaction. Later on, the exploitations of real services got more complex, and you had to reply something to the worm to fool him.

Nowadays worms use API to access services, before sending their payload. To allow easy adjustments to the procotol, dionaea implements the protocols in python. There is a glue between the network layer which is done in the c programming language and the embedded python scripting language, which allows using the non-blocking connections in python.

This has some benefits, for example we can use non-blocking tls connections in python, and we even get rate limiting on them if required , where pythons own io does not offer such things. On the other hand, it is much more comfortable to implement protocols in python than doing the same in c. SMB has a decent history of remote exploitable bugs, and is a very popular target for worms.

As scapys own version of SMB was pretty limited, almost everything but the Field declarations had to be rewritten. Besides the known attacks on SMB dionaea supports uploading files to smb shares. Patches are appreciated. For https, the self-signed ssl certificate is created at startup.

From my own experience there are very little automated attacks on ftp services and I'm yet to see something interesting happening on port Even though there were vulnerabilities in tftp services, I'm yet to see an automated attack on tftp services. It can decode queries run on the database, but as there is no database, dionaea can't reply, and there is no further action. Patches would be appreciated. It simply waits for incoming SIP messages e. As sophisticated exploits within the SIP payload are not very common yet, the honeypot module doesn't pass any code to dionaea's code emulation engine.

This will be implemented if we spot such malicious messages. If you want to volunteer, just send me patches. Exploitation Attackers do not seek your service, attackers want to exploit you, they'll chat with the service for some packets, and afterwards sent a payload.

In order to do so, dionaea uses libemu. Given certain circumstances, libemu can detect shellcode, measure the shellcode, and if required even execute the shellcode. Shellcode detection is done by making use of GetPC heuristics, others wrote papers about it, we decided to write libemu to do so.

This detection is rather time consuming, and therefore done using threads. For most shellcode profiling is sufficient, the recorded API calls and arguments reveal enough information to get an idea of the attackers intention and act upon them. For multi-stage shellcode, where the first exploitation stage of the shellcode would retrieve a second shellcode from the attacker, profiling is not sufficient, as we lack the information 'what to do' from the second stage of the shellcode, in this case we need to make use of shellcode execution.

Shellcode execution is basically the same as shellcode profiling, the only difference is not recording the api calls, and we allow the shellcode to take certain actions, for example creating a network connection.

In both cases, dionaea offers an cmd. BruteForce Lab's Blog security, programming, devops, visualization, the cloud. Home Main page HoneyDrive Honeypots in a box!

Kippo-Graph note ». Categories: Honeypots , Malware by Ion. I started Dionaea with:. Tags: Dionaea. Thanks Leon, I will check both of them out today and report back. Hi Leon van der eijk There are some websites that can show malware attacks in the world map! Do you know how to use them? I implemented Dionaea and I want to use those kind of sandboxes! Hi Leon van der eijk , How to combine this dionaea malware honeypot with my cuckoo sandbox?? I will install Dionaea on Ubuntu Regards, George.

Then, if you followed the default Dionaea installation instructions you can just run it with: chmod mimic-nepstats. Hi Ion, Thank you very much. I will inform you about results. Hi Ion, I just installed Dionaea on Ubuntu Hello again George. Let me know how it goes. Thanks a lot!

I saved it on Desktop. When I run: chmod mimic-nepstats. Hello George, just try: python mimic-nepstats. Hello Eyal. Note: x. Hello George, well… It is what it is actually Your honeypot was attacked and two binaries have tried to spread over to your system from two different IPs. Hi Ion, Maybe, Do you know any honeypot that currently capture malware successfully?

Have you heard about Surfnetids? Have you used it? Hello George. Hi Ion, I have questions regarding Honeyd and Kippo. I can do work Amun and Honeyd in the same host? I can do work Dionaea and Kippo in the same host? Hi Ion, Thank you very much for your answer. Hello George, this could simply mean that there are no malware in the internal network. Hi Ion, Please, I have another question. Erik Giraldo. Yes I am always paying attention to honeypot-related topics First things first, about Dionaea, the config file I think is mostly self-explanatory inside.

Hello again. Hm, it all depends on what you are trying to accomplish. Dear Ion, Thanks a lot for your answer! Thanks again. Regards, Ion. Thanks a million, I really appreciate your helps. Hi shahrooz, if you enable submission to automated malware analysis engines like Norman Sandbox and Anubis in the dionaea. This is sufficient for profiling most shellcodes; but not for multi-stage shellcodes. In addition to recording API calls and arguments, we need to allow shellcodes to take actions e.

Once we obtained the payload and its profile, we have to act upon it in order to acquire a copy of the malware. Following are some common techniques used by attackers, and how Dionaea act upon them:. However, similar to any other services, logging to text files is not a scalable solution.

In addition to that, Dionaea uses a communication system that is much superior to text logging known as incidents. One advantage of using incidents logging is the ability to cluster information based on the initial attack when retrieving data from the database. That was until I created an incident and had to get access to the connection object to pass it to the incident object.

The next section will discuss the Python code, and the section following will explain the regular expression that extracts the URLs from the ShellShock exploit string. See dionaea-shellshock. If you want to download it and use it to patch the Dionaea source code, then you should download the base64 encoded version and decode it to ensure that you get a byte-for-byte copy. The rest is new code.

The calls to str lines 47 — 48 are necessary to convert an array of bytes which were just ASCII characters to a string. Now for the first regular expression line That is the first of our two regular expressions.

This regular expression is used to determine if a header value contains the ShellShock exploit. Moving on. If this regular expression match succeeds, then we have a ShellShock exploit and we can go on to see if it contains a command to download a URL, which is where the second, and hairier, regular expression comes in line The code then uses a for … in … loop line 66 to iterate through any URLs matched by the regular expression. If this is a new URL for this connection , then we create a Dionaea dionaea.
