Hacking

... and NOT attacking. Hacking is definitely not attacking. Hacking means here to take advantage of a computer system to make advanced/unexpected interesting computing systems.


Ph0wn: workshop and CTF

I am one of the main organizer of the ph0wn security competition. Ph0wn is a Capture The Flag (CTF) dedicated to smart devices.


Security challenges (CTF - Capture The Flag)

I like (love?) participating to security challenges. Security challenges are settled by hacking teams to challenge other hackers with practical security problems: reverse engineering, attacks on websites, attack on network streams, attacks on embedded systems. I do insist on the fact that the challenges are made on fake systems, and definitely not on real webservers or computing systems.
The name of my team is pic0wn.

Fighting Android malware

(Note: malware stands for "MALicious softWARE". A virus is a specific king of malware that can infect files and have ways to spread from one computer to another one).

Android malware unfortunately have little difficulty to sneak in marketplaces. We estimate than more than 2k Android malware are released everyday. While known malware and their variants are nowadays quite well detected by anti-virus scanners, new unknown malware, which are fundamentally different from others (e.g. "0-day"), remain an issue.
To discover such new malware, the SherlockDroid (from the anti-virus company FORTINET) / Alligator framework filters masses of applications and only keeps the most likely to be malicious for future inspection by anti-virus teams. Apart from crawling applications from marketplaces, SherlockDroid extracts code-level features, and then classifies unknown applications with Alligator.

Alligator is a classification tool that I have developped. It can efficiently and automatically combines several classification algorithms.

Identified unknown Android malware

Android/MisoSMS.A!tr.spy, Android/Odpa.A!tr.spy, Adware/Geyser!Android, Riskware/Flexion!Android, Riskware/SmsControlSpy!Android, Riskware/Zdchial!Android, Riskware/SmsCred!Android, Riskware/Blued!Android, Riskware/SneakFont!Android, Virus: Riskware/SAppLock!Android, BadMirror: New Android Malware Family Spotted by SherlockDroid, etc..

Home automation / Domotics

I automate my house with my own solutions based on electronic boards like Arduinos and Raspberry Pi. I publishmy systems in French magazines (for instance: Hackable).
