Hello LostMyCode,
I tried reaching out to you through your discord (wildspeed) about a security issue in your code. Could you check your discord DMs from user "steakenthusiast", or provide me with an alternative form of contact?
All the best.
for some reason i cannot get it to work with this file https://pastebin.com/CSJtS8kz. I put target function a6_0x16eb. Please help.
while trying to deobfuscate the code obfusacted by obfuscator.io im getting the error: "Invalid obfuscation type! Please report to us or try again."
it didn't working......
https://obfuscator.io/
example code:
function hi() {
console.log("Hello World!");
}
hi();

Getting 'invalid obfuscation type' with any target function (tested hi and _0x2258) and 'Server error! Please check target code and name of target function.' when tryed _0x3c34 as target function
In fact I need to deobfuscate much bigger script, but get same problem :)
var obf = ["aaa", "bbb", ["ccc", "real"]];
console.log(obf[2][1]); // output = real
[Error] Server error! Please check target code and name of target function.
Nice project. Especially eval.
Will try to break this deobfucator.
lol i just randomly found this while testing stuff
test with opera gx (private window and normal) and chrome
code on vid
function notok(msg, useless) {
return useless + msg;
}
console.log(notok("aaaaa", "uwu"));
Please help me to decode this code?

This code won't deobfuscate. https://hastebin.com/xxxxxxxxx.js
Will you make the backend of the site open source at some point??
In the second property access, there should be a dot in the ret circle, but there is a space. This bug happens with differend JS codes too.
- _0x562f9a.target tagName
+ _0x562f9a.target.tagNameHowever, some parts work fine - like window.document.createElement. It does not become window.document createElement.
Hi. I am a dev of this repo. Can someone help my development?
My deobfuscator crashes if target code is generated with unicode escape sequence enabled.
https://hastebin.com/raw/suyubepenu
I tried to fix the problem but... :(
I want to explain more details but its hard to me (im not an english)
I cannot decode this code
https://pastebin.com/raw/CgEn0S6Y
I would love to see a number to expressions calculator
Obfuscator.IO has a feature that turns numbers to expressions eg.
(0 => -0x377 * 0x1 + 0x1 * 0x1871 + -0x1e * 0xb3)
(1 => 0x2 * 0x283 + -0x304 + -0x201)
could you make it so the program tries to automatically find the Target function name
also sometimes functions are not like these eg:
_0x439c[103]
_0x439c('0x4')
_0x439c('0x2','f]Xg')
The deobfuscating isn't working on this code

I have an error when I want deob
[Error] Server error! Please check target code and name of target function.
Why ?
did the deobfuscator "simplify" the code before sending it to the server ?,
because i tried to make my custom client and i can't seem to find where is the code simplifier
EDIT: the type of the code is 1
I was trying to deobfuscate this script but couldn't. https://pastebin.com/fAigtKUB
Thanks in advance

I put the following code which is the simple hello world script obfuscated by obfuscator.io, and try to decode _0x3c5af2.
Tring to deobfuscate caused Server error.
