My name is Yarrow Charnot. I live in Brisbane, Australia, for the last two
years until present on a part time contract as a consultant for VASCO Data
Security:
- researching new ways to break, secure and improve all kinds of
authentication procedures and protocols (mainly focused on web and LAN
authentication)
- integrating hardware token authentication into native and not so native
LANMAN / NTLM / kerberos / MSCHAP / RADIUS for NT4 and 2000 domain controllers
- analysing security of VACMAN Server and other hardware and software
products to advise on their possible integration
- designing and implementing secure intermodule communication based on AES
and DH-3072 / ECDH-512 PKI that I have developed for them (Windows, Linux,
Solaris)
- designing and implementing licensing and copy-protection
- solving problems developers get stuck with, mainly analysing and debugging
their code with SoftICE, IDA, Hiew and gdb
- educating developers on security-conscious development as security of the
product depends on every single part of it
My main area of expertise is software reverse engineering (cracking) that
requires strong skills in disassembly, code analysis, code optimization,
cryptography, cryptanalysis, mathematics, programming in Assembly and C/PASCAL
and requires a deep knowledge of computer architecture and an ability to
read/analyse/modify/rewrite code written in any programming language, which I
all possess.
Since the best reverse engineering (IDA, SoftICE, etc) and IDE development
(MSVC and Borland C/Pascal) tools and the most of work is done in DOS/Windows
environment (Linux is mainly open source anyway), I spend most of the time using
Windows. I don't mind using Linux or Solaris and gdb on them, but my knowledge
of Unix systems is on a user/cracker level so far, so I would not qualify as a
*nix administrator or as a good *nix developer.
By now I have an unmatched knowledge of Windows NT internals knowing some of
its areas better than its developers as I often see flaws in its code that
weren't apparent in the source. I can advise on design, development and analysis
of copy-protection systems, device drivers, secure communication, strong
authentication, exploits, worms, viruses, trojans, undocumented features,
unpublished proprietary algorithms, protocols and data formats. Please don't
confuse me with a hacker, a script-kiddie or an academic "security consultant".
Although I am only 30 years old, I have 17 years of experience of breaking
secure computer systems and copy-protection and anti-debugging software
beginning with PDP-11 and IBM-360/370 back in 1984-1986. As the matter of fact,
I can even determine the IQ level of the software developers just by looking at
their compiled code even though it has been optimized by the compiler.
I am single, so I'm available to travel anywhere in the world for a week or
two at any time, but I don't want to move to another area. I love Brisbane -
it's the best place to live in the universe according to my around the globe
travelling experience. My preference is working from home reversing code and
integrating the results of my research into other products (absolutely without
infringing any copyright laws as I never make illegal copies of the products to
analyse them, I just look at the code and I rewrite it all myself optimizing it
without using any copyrighted parts). Australian laws specifically permit
software reverse engineering, so American employers please don't be put off by
my Australian residence. I have lived in the USA for 3 years in quite a few
states and I feel very comfortable getting around the place - I can drive
without a map in Los Angeles, Washington DC, all over Florida and I have driven
across 20 states.
The best ways to contact me are e-mail yarrow @ charnot.com (without
anti-spamming spaces), ICQ No 527342, EFnet on IRC, or my cell phone (+61 421
580 623). I can send a more detailed resume if necessary. Please only serious
offers, no resume requests to place me in your database.
