GAME NỔ HŨHacking JavaScript Games – Accessing private javascript variables at runtime via debugging
Taigamemienphi.vn – Chuyên trang tải game miễn phí – Kho Game tổng hợp số 1 Việt Nam
JavaScript private variables cannot be accessed from the console, which makes hacking the game hard and automating it from the console hard. The game I’m using is an open source PacMan JavaScript game which is entirely called from an anonymous function. I show the debugging technique I use for making bots possible.

Hey there, nice video!
I'm trying to hack this instantgame on Facebook called Ludo King.
I have found several Function calls, but the values just don't seem to get updated on the variables. No matter what value I give the variables, they always don't change.
Also, the game's code isn't as readable as the one in the video, they seem to be like obfuscated in some manner. Could you please have a look at it when you have the time?
I understand you're exposing them after setting a breakpoint, but can't you just click on the line in the js file, edit what you want, press ctrl+s to save and it does the same thing?
5:56 how about pacman.lives = 1/0 ?
How can I window the below code?
this.validateInputs = function () {
u(function () {
if (c.toPage && c.fromPage) {
if ('0' != c.fromPage.toString().charAt(0) && '0' != c.toPage.toString().charAt(0)) return c.firstPage = c.convertPageToIndex(c.fromPage, !0),
c.lastPage = c.convertPageToIndex(c.toPage, !1),
c.validateError = !1,
c.firstPage && c.lastPage ? c.validateFromToPages() : c.displayError = a.instant('GT_BOOK_PRINT_INVALID_PAGE_RANGE');
c.displayError = a.instant('GT_BOOK_PRINT_INVALID_PAGE_RANGE')
} else c.displayError = '',
c.validateError = !0
}, 1000)
},
Try hacking Mope.io. It is a game and I would like to get unlimited coins. This has helped me a little too. Thanks!
What's the diffrence between games you can hack by changing prototype functions and those where you cant?
Hello there, very nice video, I am not very good at programming or hacking but could the same thing be done with this game? https://s2.soccerstar.dk/
only shows 2 hearts because in programming you count starting from zero not 1 aint it? lol so if you want to see 3 you need to change it to 01234
probably been asked before what about runescape. is it vulnerable
Great video, I'm working on a game where there are several "classes" within a function, which are named things like ea, Qq for example, but some variables begin with this. , for example this.health, but even in console I can't access this value, do you have any idea how I might get around this? It's confusing the hell out of me
How do you open “Find”
make a video on hacking of online game known as " the avengers destroyers" i bet u cant hack it although its a javascript game
It's so easy, it's pathetic. So much for global variables are evil. Every JS developer should watch this.
Very clever. Thanks for sharing 🙂
Hey, first of all thanks for this video. I'm new to browser games and had no idea where to start. I do have a question though, I'm trying to automate a little minigame without interfering with the timer. But to automate it I have to use a python library and thus I need to extract the javascript object, or at least some of the values, in order to use them in python. Do you know if / how this possible? Thanks!
Would it be possible to turn this into a script or a chrome extension? So that someone could use this without having to manually open the debugger and set a breakpoint
Hi there, First of all thanks for this great tutorial. I tried this thing but the game I am trying it on doesn't update my window (global) variable with the new values. Since its a ludo game, I think it creates a new object at every turn so the old one is left untouched. Please let me know what you think, Thanks.
cool
can u tell us how can we protect our games form this hack ?
thanks
amazing
but every game will have the var names randomized and will check whether u're opening debugger
Just stumbled upon this, I am the guy who coded this game, cool stuff 😉 I will watch it later and tell you my thoughts
The debugger is a really powerful thing. Hacking games is one of the simples things, that can come into your mind. It allows you to take control into your hands and do whatever you want. Very good explanation and demo.
P.S. I didn't know, that you can access them from the console while on breakpoint, so I always did that via local variables. Thanks
So creative! I almost feel dumb now that I did not think of this. Keep up the good work!
Inspiring dude!
Awesome!
