Skusali ich aj skompilovat:

v XP chybal winlogon.exe ale 2003 sa podarilo skompilovat a nainstalovat

General Discussion / Windows XP Source Code Reportedly Leaked, Posted to 4chan
« Last post by RubberDuck on September 25, 2020, 01:04:55 PM »
Reports have emerged today that the Windows XP source code has been leaked to 4chan, with the leaked code then being posted to a torrent and the Mega file sharing service. Reports have also emerged that independent researchers have since begun analyzing the data, with initial indications that the leak is legitimate. However, there hasn't been an official confirmation.

Tools / Re: haybale: Symbolic execution of LLVM IR, written in Rust
« Last post by DARKER on September 18, 2020, 12:03:43 PM »
Z dokumentacie (github.com/PLSysSec/haybale):

Okay, but what is a symbolic execution engine?

A symbolic execution engine is a way of reasoning - rigorously and mathematically - about the behavior of a function or program. It can reason about all possible inputs to a function without literally brute-forcing every single one. For instance, a symbolic execution engine like haybale can answer questions like:

    Are there any inputs to (some function) that cause it to return 0? What are they?
    Is it possible for this loop to execute exactly 17 times?
    Can this pointer ever be NULL?

Symbolic execution engines answer these questions by converting each variable in the program or function into a mathematical expression which depends on the function or program inputs. Then they use an SMT solver to answer questions about these expressions, such as the questions listed above.

Zaujimava funkcia :-)

Tools / haybale: Symbolic execution of LLVM IR, written in Rust
« Last post by RubberDuck on September 17, 2020, 05:31:27 PM »
haybale is a general-purpose symbolic execution engine written in Rust. It operates on LLVM IR, which allows it to analyze programs written in C/C++, Rust, Swift, or any other language which compiles to LLVM IR. In this way, it may be compared to https://klee.github.io/, as it has similar goals, except that haybale is written in Rust and makes some different design decisions. That said, haybale makes no claim of being at feature parity with KLEE.

ked ho to bavi, tak nie je co riesit.

niekde bolo tusim napisane, ze si zhana mikrofon, aby mohol videa aj komentovat (lebo tie zmazane boli bez komentara). predpokladam vsak, ze akonahle sa linky na tie videa dostali na viac verejnost, tak sa o tom dozvedel aj clovek stojaci za danym protectorom, tak ho hned asi kontaktoval.. a presvedcil ho, aby s robenim videi prestal :D a predpokladam, ze to bolo za tym vymazanim vsetkych videi a zaroven toho, ze frajer nemoze zohnat mikrofon na tvorbu novych komentovanych videi :D
