Malware datasets tend to be relatively large and sparse. They are mostly made of categorical and string data, hence there is a strong need for good feature extraction approaches to obtain numerical vectors that can be feed into machine learning algorithms [e.g. Back to the Future: Malware Detection with Temporally Consistent Labels; Miller B., et al.]. Another common problem is concept drift, the continuous variation of malware statistical properties caused by never ending arms race between malware and antivirus developers. Unfortunately, this makes fitting the clusters even harder and requires the chosen approach to be either easy to re-train or be adaptable to the drift, with the latter option being more desirable.

As I blogged two weeks ago, after some great student projects between 2009 and 2015, The Honeynet Project had applied again this year to be a mentoring organization in Google Summer of Code (GSoC) 2016. Read more »
Hi there, my name is Li Yuanchun and I'm glad to introduce DroidBot, a tool to improve the coverage of dynamic analysis.
As it is the case for malware targeting the desktop, static and dynamic analysis are also used for detection of Android malware. However, existing static analysis tools such as FlowDroid or DroidSafe lack accuracy because of specific characteristics of the Android framework like ICC (Inter-Component Communication), dynamic loading, alias, etc. While dynamic analysis is more reliable because it executes the target app in a real Android environment and monitors the behaviors during runtime, its effectiveness relays on the amount of code it is able to execute, this is, its *coverage*. Because some malicious behaviors only appear at certain states, the more states covered, the more malicious behaviors detected. The goal of DroidBot is to help achieving a higher coverage in automated dynamic analysis. In particular, DroidBox works like a robot interacting with the target app and tries to trigger as many malicious behaviors as possible.
The Android official tool for this kind of analysis used to be Monkey, which behaves similarly by generating pseudo-random streams of user events like clicks,touches, or gestures, as well as a number of system-level events. However, Monkey interacts with an Android app pretty much like its name indicates and lacks any context or semantics of the views (icons, buttons, etc.) in each app. Read more »
dpkt is a Python library that helps with "fast, simple packet creation/parsing, with definitions for the basic TCP/IP protocols". It supports a lot of protocols (currently about 63) and has been increasingly used in a lot of network security projects. It is 44x faster than
Scapy2, and 5x faster than
Scapy no longer in development,
dpkt is the only network creation/parsing library for Python that is active. Read more »
Rumal was developed by Tarun Kumar during the Google Summer of Code 2015 program, and its goal is to provide a web GUI for Thug. Read more »
Although it is still winter in much of the northern hemisphere, for students and open source software developers, the gradually lengthing days mean that spring will soon be with us - and of course that means another chance to potentially get involved in Google Summer of Code (GSoC). Read more »
In addition to providing the tools for analyzing PDF documents, we also wanted to provide some indication about how likely it is that a given PDF file is malicious. Adding such a scoring system in peepdf was one of the projects of Honeynet Google Summer of Code (GSoC) 2015 program, and the student Rohit Dua did a great job.
We are happy to announce the immediate availability of mitmproxy 0.16! As a major new feature, Thomas Kriechbaumer – who joined us as a Google Summer of Code (GSoC) Student last year – contributed a brand new HTTP/2 implementation built on top of hyper-h2. HTTP/2 requests now blend into the mitmproxy UI just like regular HTTP 1 requests, making mitmproxy the first interactive HTTPS proxy with HTTP/2 support! All HTTP/2 features from RFC7540 are supported - including PUSH_PROMISE, RST_STREAM, and as many concurrent streams as you want. We are super excited about the improvements Thomas is bringing us here and we encourage you to try them out. To make a transition as seamless as possible, HTTP/2 needs to be enabled manually for now by passing
--http2 to mitmproxy. We plan to remove this requirement with one of the next releases. For a full list of changes, take a look at the changelog posted below!
2012 was a big year for me - being only just out of my freshman year, Honeynet accepted my application as a GSoC Student and I got introduced to the world of free and open-source software development and started contributing to mitmproxy. Long story short, I think this program is one of the major reasons why I am now writing this blog post as one of mitmproxy’s core contributors. Last year, I was in the fortunate position to mentor a student myself - we’re super happy that not only Thomas’ project was a great success, but we also gained a very strong new mitmproxy contributor who is contributing well beyond his GSoC.
I am very happy to announce that we are applying under the umbrella of Honeynet as a GSoC Organization this year again. The last six years’ projects have generated long-lasting successes at Honeynet, so we can’t wait to get in touch with students this year again!

During Google Summer of Code 2015, in the Honeynet Project open-source org, Valerio Costamagna and Cong Zheng (mentor) worked on ARTDroid, an easy-to-use framework for hooking virtual-method under latest Android runtime (ART). Read more »
