Works I've done

Virtual Dynamic Shared Objects Support and Shared Page Subsystem for FreeBSD: [patch] [paper] [tgz]

The patch aims to implement a stable support for virtual dynamic shared objects on FreeBSD, by means of memory regions shared between the kernel and every user process. It is made of two main parts: a kernel side code and a user side one.

Curuncula: [src]

Curuncula is a tool shipped as a loadable kernel module which aims to detect rootkits based on the Intel debugging support facilities; rootkits which set the GD access flag are also detected.

Vsyscall Page Hijacking (italian only): [paper] [src]

Article first appeared on the italian security magazine Butchered From Inside, explaining how overbloating features in the Linux kernel can be exploited to achieve syscall redirection in an inedited way, implying new possibilities to rootkit design (namely kspace-uspace hybrid hooking).

Symbiotic Process Execution: [paper-italian] [paper-espanol]

Neither exec nor grugq's userland exec are necessary for code execution, since symbiotic sharing of process's resources is sufficient.

Claire, The Useless Signal Context Fuzzer: [src]

One night I dreamt of searching for flaws in the Linux kernel by fuzzing a process's signal context; those who are familiar with the pertinent kernel code know this is doomed to remain a dream.

Hei Jean! : [src]

When life used to be simpler, I was on the way to make a comic strip; since I am a chronic lazy person, I thought of having a software to draw images for me, and this is the first attempt toward it, completed before laziness itself had prevailed. It generates faces through linear combination of eigenfaces obtained from a training set. (meschach and libsdl needed. Best results achieved with The Japanese Female Facial Expression (JAFFE) Database).

Things I find worth looking at
