Valve got it wrong once again

So you may remember the incident from a long time back when a whole bunch of Modern Warfare 2 users got VAC banned for no reason.

For those who haven’t been following the VAC team they have been in somewhat of a hibernation over the past months as VAC bans handed out were not targeting specific P2Cs (Pay 2 Cheat). However more recently they have come back and are now actively targeting cheat providers again. The last update to Steam shows that VAC3 is now loaded when you sign into an account this isn’t really an issue if you know the ways around it (I have a VAC disabler in the works coming soon to but they are more aggressively scanning for cheat software now before a VAC secured game is even launched.

This aggression has shown some downside as some false positives were in fact stated by the VAC team today on reddit.


Research work on VAC and such will most likely be posted on UnknownCheats or this blog if you are interested.

Teardrop WIP

I’m working on a DLL injector which utilizes the various techniques of remote code injection. I haven’t really done any research or anything interesting hence my lack of posts on this blog.

VAC3 Dump (5/04/2016)

VAC3 Dump (5/04/2016)

So the CSGO majors are over, hoping for a big ban wave to flood out the idiots in the scene decided to do a vac3 dump to see if anything has changed since it’s been a good 3 months since I’ve last looked at VAC. There was a few modules deployed prior to this month

Full download of the modules can be found on UnknownCheats

CSGO : Far ESP Concept #2

Counter-Strike Global Offensive Far ESP Concept #2


As mentioned previously in my other concept point, Valve have disabled the networking of dormant players in CSGO. Dormant meaning the players who your client should not be rendering as they are invisible to you by occlusion of objects or are outside the visibility leaf in the BSP tree. More in-depth information about these concepts can be found below:

These systems are utilized on Valve official servers however there are other techniques 3rd parties use to extend the functionality such as the anti-wall feature in SMAC which is used by leagues use to prevent people wall hacking. The concept presented in this post looks at another way of bypassing this and allowing the user to see the enemy players from anywhere on the map.

!!!Note I’m not going to reveal how this works just yet. This is a concept point only!!!

The Source Dedicated Server (SRCDS)

Although we are going to be looking at Valve’s own instances of srcds they deploy in match-making this should work on any other server too.


There is a way, well rather¬†various ways to interact with the game server and receive information that is not suppose to be disclosed to you. I’m going to be utilizing one of those¬†ways in this demonstration. There are limitations to this method as you will soon see but it works fine so far.

A usual competitive game in CSGO has 5 players on each team. One of the players we use as a relay who captures the enemy player information (eg. position data/health/current weapon) and relays that information to the other connected players. To make the connection easier a server is utilized. Here is a diagram:


Our 5th player (modified spectator client) is receiving data from the game server for all connected players (friendly/enemy). This information is then sent to the relay server which then broadcasts it to each of the other four connected clients. Information can be received and either drawn on a mini-map radar or can be drawn as an ESP like so:



The advantages and disadvantages are pretty obvious. You get the information you need about the enemy team but you pay the price of a fifth player being absent.

Further work

This concept could be improved drastically if the requirement of a 5th connected player was removed. Maybe have an external client connected somehow? Any questions contact me via email me[AT] or twitter @cra0kalo

Happy ‘late’ New Year to everyone.

I will continue my work on cVision in the coming months along with some other projects I have in mind. Stay tuned.. and oh yeah look out for this soon.

More UI work I’ve done over the break.

[REL] LiveDump

LiveDump – A simple memory dumper

I’m a fan of 010 Editor‘s templating system they have in place where you can write layouts for hex dumps or file formats I use it in almost all of my research/reversing. More information about that can be found here¬†even though the hex editor has a built in system to open a live processes memory it’s not really great. I needed a system where the data I was looking at was live and updated almost instantaneously so I wrote LiveDump. LiveDump is a simple memory dumper which will either dump a region of memory once to a file or constantly dump it every X many milliseconds, this way I can see the data updated almost live in 010 editor and make use of their templating to reverse a portion of a data structure or class object. There are things like Reclass which are purposely built for this reason which I do use however my own personal preference is the templating feature built into 010 editor as it’s very robust and you incorporate loops and logic into it to display the data out how you want it.


Usage: Select the process from the process list, then enter an address and size. The address and size input fields accept both decimal and hexadecimal numbers, if your input is going to be hexadecimal then you must add a ‘0x’ prefix or ‘h’ postfix to the numerical value. Now either begin dumping continuously to a file by hitting “Begin Dump” or “Dump Once” if you wish to dump only once. | SHA1: 934fb95654cb05d2168e1e707a5cc80418380d4f

[REL]Cheat Engine Trainer Decryptor/Unpacker

So someone uploaded a pretty dodgy looking binary to¬†and since I moderate the uploaded files and determine if they are safe or not I decided to take a look at the particular submission, turned out to be a safe Cheat Engine trainer (sfx). Cheat Engine allows you to create trainers which include the Cheat Engine base along with the Cheat Engine table which stores the basic offsets and memory edits a user would of created, they allow this to be saved in an ‘encrypted’ manner to stop script kiddies from stealing each others CE tables. The author stated in the source code that this is very trivial however¬†stops most of the idiots who have no idea what they are doing stealing tables. Anyway I wrote a small tool to automatically decrypt them back into plaintext xml. Sorry kids no binary here¬† ūüôā

[REL] Overwatch Revealer

For all that don’t known (and no I’m not referring to Blizzard’s new game) CSGO has a system called Overwatch where basically people who have been reported for cheating get their demos reviewed¬†by other players or “overwatchers”. Typically these demos are stripped of all? most? information about the suspected cheater player, this includes their name, text chat, gun names (if any custom names are given to weapons) and other player names leaving the person watching the demo unaware of who it is they are reviewing. Now this is great as hopefully people who are doing these overwatch cases are not biased towards a certain player because of their name/display picture or even inventory. But hey in my opinion it’s no fun so I’ve made this tool which will reveal the suspected player¬† ūüėõ


Here are some case examples I’ve done before: Image1 | Image2 | Image3


Anyway here is a short video I made showcasing the tool.
