A Formal Introduction

Welcome! Welcome to my official homepage!

I am Viktor Andryushchenko. Currently, I am a Cybersecurity analyst/Network/System/ Security admin / CISCO Engineer / OS Maintainer / Kernel Debugger / Bug Hunter.

Linuxes: gentoo (from 2001), arch, solaris, fedora rawhide , suse leap, debian related. Can work with any type of linux related system. Maintaining my own distribution based on dietlibc ( dynamic ).

The Innocuous School Life...

I was born at small Ukrainian village Yaruga - world known village - Righteous of the World - village of Peace. Yaruha
And I brought up at Vinnytsa - one of the most beautifull towns in Ukraine. (yes, at "Spy town"). I have successfully completed my school education from Vinnytsa Physics-Mathematics School-Gymnasium N17, Vinnytsa.
I finished Gymnasium with silver medal.
Twice I represented the Ukraine on Olympiade of Mathematics and once on Olympiade of Informatics. I am also represented a district in Olympiades of Chemistry, Physics and Astronomy.

Bachelors, Masters, and Getting Started with Research...

After spending long time (1984 to 2001, to be precise) there, I joined the Department of IT of Vinnytsia National Technical University... Vinnytsia_National_Technical_University
I finished University with Red Diploma with distinction.
I also represented Vinnytsa University on Olympiade of Physics.

My FIRST WORK...and Rest

Years 1997-2000. "National Bank of Ukraine. Vinnytsa" I was one of the admins. Responsibility: ~300 stations, couple of network segments of ethernet and cables. Mixed Infrastructure Novell Netware/DOS/Windows. A am also managed Nortel Telecom Phones/Meridian PBX.
At 1998 the Bank send me to Great Britain to advance my education of Magistral Equipment, VOIP Switches.
1998: Company Nortel Telecom in Maidenhead and small brunch of the company Maicom in Farnham
I finished couple of courses and get my certifications at Nortell Telecom

2001-2003 Studing at Brooklyn College in Brooklyn, NY
2003-2004: "Associate Technologies". Software Engineer/Web Administrator.
2005: "Nibble-soft". Network/System Admin. Securing perimeters with my own firewall that I compiled for linux with uclibc libraries and hardened kernels. Audit. Network/Systems maintenance.
2008-2012: "Nibble-soft consulting". Security Analyst/CISCO Engineer.

PROJECTS...

For all this years up to 2022 I participated in ennormous amounts of projects. When I started my career I was able to compile fully functional operating system with optimized uclibc library. I also need to say that I did the kernel patching and hardeng as well.
For now I am maintaing my own OS distribution based on dynamic dietlibc. I compiled fully functional stage3 operational system from source.
Some one can ask why my choice was dietlibc instead of regular libraries like glibc or uclibc or musl. I did a lot of researches and tests in my Home LAB relative to speed and security of operatinal systems like Linux and Windows.
After testing practicly every lib that I was able to compile and test like glibc /eglibc , uclibc, musl, newlib and klibc I found out that most of the libc are bloated. In the process of the researches I found the link of comparisons of libc of author of musl Comparison
After some calculations and ennormous believes that I can beat musl library by optimizing dietlibc, I started to invest practically all my free time for optimizing dietlibc.
I did hardened loader and optimized some of most used functions. The language that I choose is Assembler. Some one can say that I am insane to do Optimization on Assembler for Linux but I did not give up. Partually my work was inspired by Danish Proffesor of Technical University of Denmark (DTU). The Name is Agner Fog. I was also inspired by team of dietlibc wich work I tried to optimize.
All of this years I followed lovely slogans from dietlibc: Person who say it cannot be done should not interrupt person doing it. --Chinese Proverb and program-like-a-klingon. "(from Startrek)" As the result of all this researches and development this project was divided to two separate projects
Nybblex - fully functional distribution based on dietlibc. For now I am using regular linux kernel that I hardened by myself. But It is temporary solution. I working on my own kernel that will protect itself from hackers attacks with some elements of AI.
BIO-Nybblex - Distribution that heavily optimized for speed and needed in research facilities and BIO-Labs. Test Examples: You can find test tables on project pages for most used in BIO Labs tools like bedtools and others and big tables of CPU with benchmarks. Project related to Biochemistry/Bioengineering/Bioinformatics. Live distribution based on linux. The goals of the project is highly optimized tools needed for intensive and heavy computations related to DNA analysis and other tasks.I choose dietlibc libs instead of uclibc, musl , newlib. My work: analysis of needed applications that used most in bio-labs (like bedtools, bioperl, biogrep, bamtools, bcmtools, bamtools ... others ).
I did more secure application loader for dietlibc on x86 platform, and optimize some most used functions. Another goal: Such distributions can be used in other industries that needed very fast , highly optimized computations of databases or other statistical data.
"Sensor array" : on the top my sensor array every 2.4Ghz channels and some logic with sniffing 5 Ghz. I have also LTE/4G/3G/2G hardware sniffers. I am using mostly alfa cards but have others for testing. Enormous amounts of different cards and models Studying WIFI and Ethernet Drivers (Windows/Linux/Android/Mac OS).
For now I have updated the Sensor array. Instead of using the old Dell Pentium 4 , I moved to a Raspberry Pi 5 device and 4 hubs in total 28 USB ports.
The main goal is to study anomaly in wifi networks, so If someone using software evil twin AP or hardware like Wifi Pineapple, Flipper Zero, ESP32 Development Boards, changed own MAC address, deauthenticate the clients and AP and other questionable activity You can momentarily see such anomalies.

Neirointerfaces...

It can be very helpfull. For many tasks. You can find some info on my My FACEBOOK Creating real-time neuro-feedback framework, that can be used for variety of tasks. The device that I using is: EMOTIV EPOC+ neurointerface. It can do EEG. Usable to send predefined sets of command to the computer. It can type, it can run any application, or You can flu a drone . It depends on learning task. It can capture real-time EEG data everywhere ~24hrs (if You change the battery). EEG Data can be captured on the phone or computer. I didn't finish analysis of EEG Data part yet, but capturing is Ok. It can be very helpful for IMPAIRED PEOPLE. You can find on youtube, that the device can be really helpful.

If You want to study more professional equipment You are free to look for specific equipment like wearing hats.
Neuroengineer Dr. Rajesh Rao of the University of Washington is developing brain-computer interfaces, or devices that can monitor and extract brain activity to enable a machine or computer to accomplish tasks, from playing video games to controlling a prosthetic arm. "Mysteries of the Brain" is produced by NBC News Learn in partnership with the National Science Foundation.
