Hello there! My name is Emanuel and I’m based in Zürich, Switzerland.
Currently I’m doing my MSc in Cyber Security at ETH Zürich, while working part-time as a research assistant at the ETH Network Security Group.
I’ve been writing code and hacking stuff for more than a decade. I am into CyberSec, Mobile Development, IoT, Electronics and all other related black magic. Here you can find all about me, and read about stuff I find worth sharing.
A collection of smaller home automation projects built on open source solutions from others. From magically opening entrance doors to RGB ambience behind every piece of furniture, and a standing desk that obeys Siri.
A writeup about exploiting an image converter service through path traversal and multiprocessing pickle deserialization. The solution required crafting a polyglot file that’s both a valid BMP image and a malicious pickle payload to achieve RCE.
A writeup for EPFL CS412’s HEAP-MEANU challenge involving heap exploitation through one-byte overflow and constrained brute-force reading. Despite full protections and modern libc 2.39, achieved RCE using a House of Spirits like attack.
How I taught my apartment’s entrance door to recognize me and open automatically. A surprisingly practical tale of BLE authentication, hidden ESPs, and the occasional accidental door opening while driving by.
When your loft flat turns into a sauna every summer, the logical solution is obviously to reverse-engineer a decades-old proprietary bus protocol. A tale of digital archaeology, improvised level shifters, and ladder-based near-death experiences.
