applepie | A hypervisor for fuzzing built with WHVP and Bochs

kandi X-RAY | applepie Summary
This is a tool designed for fuzzing and introspection during security research. By using a hypervisor common fuzzing techniques can be applied to any target, kernel or userland. This environment allows fuzzing of whole systems without a need for source of the target. At the hypervisor level code coverage can be gathered, and if needed Bochs emulation can be used to provide arbitrary introspection in an emulation environment. This coverage information can be used to figure out the effectiveness of the fuzz cases. A fuzz case that caused an increase in coverage can be saved as it was an interesting case. This input can be used later, built on by new corruptions. Snapshot fuzzing is the primary use of this tool. Where you take a snapshot of a system in a certain state, and save it off. This snapshot can then be loaded up for fuzzing, where a fuzz case is injected, and it's resumed. Since the VM can be reset very cheaply, the VM can be reset often. If it takes Word 5 seconds to boot, but you can snapshot it right as it reads your file, you can cut the fuzz case down to only what is relevant to an input. This allows for a very tight loop of fuzzing without needing to have access to source. Since the VM's are entirely separate systems, many can be run in parallel to allow scaling to all cores. Currently this tool only supports gathering code coverage, dynamic symbol downloading for Windows, and symbol/module parsing for Windows targets as well. Adding fuzzing support will be quite soon.

Answered 2022-Jan-23 at 06:35For Excel 2013
, assuming the same layout as per JvdV
's screenshot, and that you place your punctuation marks in C1
, C2
and C3
, formula in E1
:
=SUMPRODUCT(2+LEN(B$1:B$4)-LEN(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(LOWER(" "&B$1:B$4&" "),C$1," "),C$2," "),C$3," ")," "&D1&" ","")))/(2+LEN(D1))
and copied down.
An additional SUBSTITUTE
clause will be required for each additional punctuation mark added below that in C3
. For example, with a new entry in C4
, the above becomes:
=SUMPRODUCT(2+LEN(B$1:B$4)-LEN(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(LOWER(" "&B$1:B$4&" "),C$1," "),C$2," "),C$3," "),C$4," ")," "&D1&" ","")))/(2+LEN(D1))
Then, for the lists, in F1
:
=IFERROR(INDEX($A$1:$A$4,AGGREGATE(15,6,(ROW($A$1:$A$4)-MIN(ROW($A$1:$A$4))+1)/ISNUMBER(SEARCH(" "&$D1&" ",SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(LOWER(" "&$B$1:$B$4&" "),$C$1," "),$C$2," "),$C$3," "))),COLUMNS($F1:F1))),"")
and copied right until you start to get blanks for the results. This formula can also be copied down to F2
, F3
, etc.

The following code includes several different ways of declaring a static variable used by a class. Are there any functional differences between them? Are there any advantages/disadvantages for each one? Is there a better way that I don't know about?

QUESTION
I'm a newbie, and I try to learn to set a search function for finding recipes with ingredients, but I'm stuck with the partial string...
I want to find recipe even if I type partial string (like "apple" for "apples" or "choc" for "chocolate"), but I want to return only the recipes with the full list of ingredients matching the input (if someone type "apple juice" he must not find "apple pie")
How to find the recipe even if the input word is not complete as the recipe's ingredients ?
If someone can help me...
Thank you

...ANSWER
Answered 2021-May-07 at 18:12You are instantiating a contract inside another contract which is inhering the callee. Kinda circular reference.
When you inherit a contract(Project1) from a base contract (Project 2), the inheriting (Project1) should be the one that makes the calls. Your (Project2) contract acts like a base contract. The inheriting contract (Project1) can call or override all the functions in the base contract if needed. So here my suggestions (it's one way among many to solve your problem). See below. I compiled it and deployed and it works. Don't forget to provide an address when deploying. I hope this would help. If you have other questions you reach to me.

QUESTION
This is very hard to explain which is probably why I can't find an answer. For example, I have one table of "recipe", "ingredient". Ingredients would obviously be reused for different recipes so I can't use UNIQUE, but I want the command to refuse any attempts to insert into the database of a specific recipe where the ingredient already exists in that recipe.
For example, a record: ingredient = "apple", recipe = "applePie"; don't allow the insertion of another "apple" with the field recipe = "applePie" (in my actual application, other fields besides this may exist, they may be different on both records but they both have the same ingredient and recipe, so the second attempt to insert a value should be refused unless the ingredient does not exist).
Sorry if this is incredibly basic, I thought there must be a way to natively handle this without needing my program to select and compare within the code. I don't know how well I explained everything, please let me know if you need clarity.
Thank you!

I have an array with strings: const fruits = ['Apple', 'Banana', 'Orange']
I am trying to write a function that returns true or false depending on if a string starts with any string in the array, which would be true for example 'Applepie'

I found startsWith()

Install applepie
Recently updated MSVC compiler (Visual Studio 2017)
Nightly Rust (https://rustup.rs/ , must be nightly)
Python (I used 3 but 2 should work too)
64-bit cygwin with autoconf and GNU make packages installed
Hyper-V installed and a recent build of Windows 10
This install process guide was verified on the following:. This initial build process may take about 2 minutes, on a modern machine it's likely 20-30 seconds.
Make sure Windows 10 is fully up to date We use some bleeding edge features with WHVP and only latest Windows 10 is tested
In "Turn Windows features on or off" Tick "Hyper-V" Tick "Windows Hypervisor Platform" Click ok to install and reboot
Install VS Community 2017 and updated Desktop development with C++
Install Rust nightly for x86_64-pc-windows-msvc
Install Git Configure git to checkout as-is, commit unix-style If git converts on checkout the ./configure script will fail for Bochs due to CRLF line endings This is core.autocrlf=input You can also use checkout as-is, commit as-is This is core.autocrlf=false
Install Cygwin x64 via setup-x86_64.exe Install to "C:\cygwin64" Install autoconf package (autoconf package) Install GNU make (make package)
Install Python I installed Python 3 x64 and added to PATH Python 2 and 32-bit versions should be fine, we just use Python for our build script
Open a "x64 Native Tools Command Prompt for VS 2017"
Checkout applepie via git clone https://github.com/gamozolabs/applepie
cd into applepie
Run python build.py This will first check for some basic system requirements It will build the Rust bochservisor DLL It will then configure Bochs via autoconf It will then build Bochs with GNU make from Cygwin
