Hacker | SOCIAL MEDIA PHISHING TOOL | Media library

I am a beginner to nodejs and I am creating my web app. I use passportJs for authentication. As it is mentioned in the documentation that when the user is successfully authenticated, req.user will be created and can be accessed in any route.

My admin.handlebars

I'm trying to configure a simple network structure using Vagrant as depicted in the following figure:

As you can see I aim to simulate a hacker attack which goes from attacker through router and reaches victim, but that's not important for the problem I'm struggling with.

This is my Vagrantfile so far (VritualBox is used as provider):

I have a game uses Firestore, When the player complete the certain level the game will give him 50 points and will be save the data in Firestore.

Let's suppose someone did reverse engineering for my game and made change from 50 points to 1000 points in code and he rebuild the APK and play my game with the same Firestore database, Now when the player complete certain level the game will give him 1000 points and will be save the data in Firestore and that considered hacked data.

I don't care if someone did reverse engineering of my game and republish it as new game with his own Firestore, But I care about hackers who changed the data on my Firestore

How can I secure my game from fraud and abuse.

I made up a game called password hacker in C++, purpose is to guess the password through given hints, when I input the correct password, it works correct, and moves to the new level as well.

But it does the same even when I input wrong password as well.

PROBLEM STATEMENT :

Find maximum difference between the prime numbers in the given range. [L,R]

SOME CONDITION EXAMPLE :

Range: [ 1, 10 ] The maximum difference between the prime numbers in the given range is 5.

Difference = 7 - 2 = 5

Range: [ 5, 5 ] There is only one distinct prime number so the maximum difference would be 0.

Range: [ 8 , 10 ] There is no prime number in the given range so the output for the given range would be -1.

Range: [ 2 - 7 ] . This should return 5. [ 7 - 2 ] = 5

R Code :

The below R code works fine in R studio for all input I have passed. But when I ran the similar code in hackerEarth Env. Getting Errors

I'm having an isse with a code that computes the number of hours worked for a set of hourly employees, I can't get the information to line up.

I have the basic information of the code, as shown here:

Something I can't wrap my head around. As I understand the authorization code flow is supposed to be more secured than the implicit flow, because the tokens are not directly sent to the client from the authorization server, but rather retrieved by your backend. So the flow is basically:

1. Browser gets the authorization code (as a URL parameter of sort).
2. Sends it to a public backend endpoint.
3. The backend sends the code + client secret to the authorization server, retrieves the tokens and stores them in the client's cookie/local storage for further use.

In this flow all the tutorials describe the authorization code as useless to the hacker, why is that? Can't a hacker use Postman or some other client and access your (public) API directly, make it go through step 3 and thus retrieve the tokens just the same?

What am I missing here?

Can someone explain what is the idea behind server side encryption on AWS S3? What are we protecting with Server Side encryption? From whom?

If someone gets access to my account, this encryption is of no use - because the user will always get the decrypted data. And without access to my account, un-encrypted data is as safe. Are we protecting the data from a potential hacker who gets backend access to my S3 bucket? That comes under "Security of the cloud" and is AWS responsibility! Why should I pay for it?

Am I missing a point here? Can you please explain?

I am trying to perform case modification with bash/zsh parameter expansion on macOS (11.4) and making some mistakes. Specifically, I want to take a variable that contains a string and turn it to snakecase (i.e.: from This is a STRING to this_is_a_string). I am taking baby steps and so far I am just trying to turn everything to lowercase and, as far as I understand it, the theory should work like this:
