The document discusses hacking arcade machines by exploiting vulnerabilities in how game profiles are loaded and signed from USB drives. Specifically, it finds that the game In The Groove 2 does not properly check if profile data is from an arcade machine or personal computer, allowing injected Lua code. It then details how to sign a rogue profile with the private keys, which are shared between arcade machines, and use it to run arbitrary code covertly by inserting a malicious USB drive.

"Computer Games Inner Workings" - a presentation by Ioannis Loukeris, AIT Senior Web Developer and Golden Age CTO.
This presentation was given to a group of SFS students at GW. It's designed to be semi-case study driven on the problems I've encountered on assessments and how programming can help solve them.
Software geeks fear hardware. It's a fact of life: code is easy to write and easy to change, but hardware catches on fire if you put it together wrong. But this is changing! Hardware is becoming cheaper and easier to work with every day and can often be managed with the same tools you use to deploy code to the cloud. Join self-described software guy and hardware-phobe Ronald McCollam for a guided trip from the safe world of web development to the scary lands of hardware and back again. We'll see how easy it can be to make the leap from managed code to microprocessors!
I was asked to talk in front of Computer science students at the Bar-Ilan university about "what happens" when you don't care about writing "secured" or "safe" code. A perfect example for that, in my opinion, was the world of embedded computing AKA the IoT. I talked about the history of consumer embedded devices and showed a live demo of an 0day I found in one of the most popular routers in the country.
With a surge in the production of internet of things (IoT) devices, embedded development tools are becoming commonplace and the software they run on is often trusted to run in escalated modes. However, some of the embedded development tools on the market contain serious vulnerabilities that put users at risk. In this talk we discuss the various attack vectors that these embedded development tools expose users to, and why users should not blindly trust their tools. This talk will detail a variety reverse engineering, fuzzing, exploit development and protocol analysis techniques that we used to analyze and exploit the security of a common embedded debugger.
Castle Game Engine and the joy of making and using a custom game engineMichalis Kamburelis
Presentation about Castle Game Engine ( https://castle-engine.io/ ) at GIC 2022 conference. We briefly show Castle Game Engine features then talk about important reasons and things you should take into account if you want to be as crazy as me -- and develop your custom engine :)
Web application security and why you should review yours, is a whole stack look skydive without a parachute, let's try not to die as we explore what is an attack surface, Arcronym hell, Vulnerability naming, Detection or provention is there a place for both or none, emerging oss technologies which can help you, a firehose review of compromises 2014 through 2018, and finally a live compromise demo covering everything we've discussed as being 'bad' ... or as often happens the backup video.
Yocto project has been used at Open-RnD for building a number of IoT related products. The talk will go though the details of integration of Poky build system and OpenEmbedded layers into 3 projects carried out at Open-RnD:
an antonomous parking space monitoring system
a distributed 3D steroscopic image acquisition system
a gadget for acquisition of metabolic parameters of professional athletes
The presentation will approach to building software, automation and upstreaming of fixes.
Open-RnD is a small software company from Łódź, Poland. We have started using Yocto/Poky in late 2013 as a better alternative to in-house build system. Since then, we have successfully implemented a number of projects based on Poky. The presentation will go through the details of 3 projects that cover a diverse range of applications:
an autonomous parking space monitoring system (ParkEasily)
a distributed 3D stereoscopic image acquisition system (Ros3D)
a gadget for acquisition of metabolic parameters of professional athletes (Sonda)
We only use widely available hardware platforms such as BeagleBone Black, Raspberry Pi, Wandboard or Gateworks GW5400 (not as widely used as the previous ones, but still fully supported), hence all the points made during presentation are directly applicable by professionals and hobbyists alike.
Working with software means working with bugs. Bugs in software, bugs in hardware; bugs in Open Source code, bugs in proprietary code. If software is eating the world, bugs might end up taking the first bite.
We will present a few typical bugs, some of them famous, some of them infamous (including bugs that actually killed people). Since one can never be too well-prepared to fend off the next infestation, we will give tools, tips, and best practices to fix bugs in Open Source software. We will give real world examples of Really Mysterious Bugs (sometimes nicknamed "Heisenbugs" because they tend to disappear when you try to observe them), and how they were fixed, in Node.js, Docker, and the Linux Kernel.

As a film director, I have always been awestruck by the magic of animation. Animation, a medium once considered solely for the amusement of children, has undergone a significant transformation over the years. Its evolution from a rudimentary form of entertainment to a sophisticated form of storytelling has stirred my creativity and expanded my vision, offering limitless possibilities in the realm of cinematic storytelling.
In the vast landscape of cinema, stories have been told, retold, and reimagined in countless ways. At the heart of this narrative evolution lies the concept of a "remake". A successful remake allows us to revisit cherished tales through a fresh lens, often reflecting a different era's perspective or harnessing the power of advanced technology. Yet, the question remains, what makes a remake successful? Today, we will delve deeper into this subject, identifying the key ingredients that contribute to the success of a remake.

arcade machines.
7. Attack Surface (2)
● The obvious attacks won't work, as we'll get
kicked out of the arcade or worse.
● We want to be less conspicuous than this:
8. Attack Surface (3)
● Modern arcade machines often allow for
transferable profiles stored on portable devices.
● Magnetic cards
● Konami e-AMUSEMENT smart card
● USB dongles
● Probably more schemes, especially in Japan.
● This gives us more attack surface using either
malicious hardware devices, or by malicious
data on official devices.
9. Attack Surface (4)
● We pick the easiest attack surface.
● Consider game profiles loaded from and stored
to USB dongle.
● If profile handling is done wrong, we can simply
insert a USB dongle with malicious payload.
● Very covert: inserting a dongle is a common task
performed by many players, and won't attract
unwanted attention.

Attack here.

Not here. Attack here.
12. What are we attacking?
● In The Groove 2
● Dancing simulator made
by RoXoR games.
● Uses USB dongles to
store profiles.
13. What are we attacking?
● In The Groove 2
● Dancing simulator made
by RoXoR games.
● Uses USB dongles to
store profiles.
● Allows geeks to dance
like Michael Jackson.
14. What do we know? (1)
● There is a PC as well as an arcade version.
● We'll use ITG2PC and ITG2AC for these versions.
● We can tinker with the PC version easily and test
our ideas.
● After testing them on ITG2PC, we try ITG2AC.
● ITG2AC is running on x86-32 Linux.
● Most of us will be in our comfort zone.
15. What do we know? (2)
● ITG2 software based on a modified version of
StepMania, an open source dancing simulator.
● Allows for easier reverse engineering.
● There is an open source project dedicated to
reimplementing the game.
● OpenITG did an excellent job at reversing and
reimplementing parts of the game.
16. What is on the USB stick?
● Edits of existing songs on the machine.
● Custom songs (needs to be enabled).
● Signed screenshots (to prove scores).
● Signed score profile and backups.
● Stats.xml / Stats.xml.sig / DontShare.sig
● Song catalogues, preferences, etc.
● ITG2AC and ITG2PC sticks are not portable
● Because the signing keys differ.
17. Stats.xml: user profile data
● XML formatted file.
<?xml version="1.0" encoding="UTF-8" ?>
<?xml-stylesheet type="text/xsl" href="Stats.xsl"?>
<Stats>
<CalorieData>
<CaloriesBurned Date='2005-02-26'
>468.587524</CaloriesBurned>
</CalorieData>
<CategoryScores/>
...
<Data>
local tab1 = { }
return tab1
</Data>
...
18. Stats.xml: user profile data
● XML formatted file.
<?xml version="1.0" encoding="UTF-8" ?>
<?xml-stylesheet type="text/xsl" href="Stats.xsl"?>
<Stats>
<CalorieData>
<CaloriesBurned Date='2005-02-26'

<Data>
local tab1 = { }
return tab1
</Data>
...
19. XML parser flaws
● XNode::LoadAttributes() has issues.
● It will scan past 0-byte if there is a double or
single quote character before it.
● tcsskip() and tcsechr() are scary, as they
always return a non-NULL pointer.
● Lots of over-indexed reads, but hard to find
over-indexed writes.
● Need a better bug.

This is not a good bug.
● Need a better bug.
21. User profile loading flaws (1)
● Profile::LoadGeneralDataFromNode() reads
XML data from the XML tree, and deserializes.
● Lot of uninteresting numeric and string entries.
● The <Data> tag seems interesting, as it
contains embedded LUA data.
● It is only handled for IsMachine() profiles, which
are stored on the arcade machine itself.
22. User profile loading flaws (1)
● Profile::LoadGeneralDataFromNode() reads
XML data from the XML tree, and deserializes.
● Lot of uninteresting numeric and string entries.
● The <Data> tag seems interesting, as it
contains embedded LUA data.
● It is only handled for IsMachine() profiles, which
are stored on the arcade machine itself.
● Are they really?
23. User profile loading flaws (2)
● In OpenITG there is an IsMachine() check.
● Not so in R21 and R23!
v29 = GetChildValue(a3, "Data");
if ( v29 )
{
string_constructor(v29, &sData);
LoadFromString(a2 + 5000, (int)&sData);
if ( GetLuaType(a2 + 5000) != LUA_TTABLE )
{
Warn((int)LOG, "Profile data did not evaluate to a table");
sub_84C3C80(*(_DWORD *)LuaHelpers);
sub_81C2870(a2 + 5000);
}
}
24. Creating a rogue profile
● We have found a way to inject LUA code.
● There's still more work to be done:
● Signing profiles with malicious LUA code.
– This requires the signing keys.
● Finding out what LUA code we can use.
– Is there a LUA sandbox?
– Can we escalate to root on the machine?
– Do we actually need to? What can we do otherwise?
25. Signing profiles (1)
● Profile signing is done using RSA and SHA1.
● Original implementation using crypto++.
● Signing: S(k-, p) = E(k-, h(p))
● Verification: D(k+, S(k-, p)) should be h(p).
● Reimplemented this using OpenSSL, as
crypto++ is complicated to use.
● Command line OpenSSL also works.
26. Signing profiles (2)
● What is signed?
● Stats.xml with the result in Stats.xml.sig
● Stats.xml.sig with the result in DontShare.sig
● This double signature is done so people can
share verified (machine signed) scores, without
their profile being copied.
● You would share Stats.xml and Stats.xml.sig
but not DontShare.sig
27. Signing profiles (3)
● We obviously want the private key.
● ITG2 signs profiles every time someone plays.
● Private key needs to be known to the program.
● Profiles need to be transferable.
● So the signing keys are shared!
● No revocation scheme in place.
● Once we leak one key, we're set!
29. OpenSSL DER to PEM
● Private key is in PKCS8 DER form.
openssl pkcs8 -in private.rsa -inform DER -outform
PEM -out private.pem -nocrypt
● Public key is in RSA DER form.
openssl rsa -in public.rsa -inform DER -pubin -pubout
-outform PEM -out public.pem
30. ITG2PC
● The private keys are simply installed.
● They obviously differ from the ITG2AC keys.
● Look for the *.rsa files.
● They come in PKCS #1 / PKCS #8 forms.
A key!
31. ITG2AC
● Dumping the private keys more complicated.
● We need to crack open the machine first.
● Attach USB keyboard and Linux disk.
● Rebooting the machine.
● Enter + configure BIOS to boot from disk.
● Mount the ITG2 XFS filesystem and have at it.
● Will not work on R23, as it rewrites the BIOS
password using nvram.ko
32. ITG2AC (2)
● We were unable to find the keys on disk.
● /itgdata contains several crypted blobs:
data0.zip through data4.zip and patch.zip.
● The keys are most likely in there, as well as the
songs and so on.
● We need a way to decrypt those files.
33. ITG2AC file encryption
● The core algorithm uses SHA-512 and AES-
192 in CBC mode.
● The AES keys are managed in two ways.
● Patch files use a static key, probably because it is
easier to deliver patches.
● The core data files all have unique keys, which
differ on all arcade machines. These are managed
by a hardware security dongle.
35. Encrypted file header (2)
● Magic will be :| for data files and 8O for patch
files.
● file_size is the size of the decrypted file, so that
padding to blocksize can be ignored.
● subkey_size is the size of the subkey.
● subkey is the size of subkey data.
● verify_block is a block of encrypted static data
to determine if a valid key was provided.
36. File decryption algorithm (1)
● AES-192 keying is used. How these keys are
derived we will see later.
● Remember that AES works on 16 byte blocks.
● File is partitioned in blocks of 255 AES blocks.
● Each of these blocks is encrypted using AES in
CBC mode.
● The IV is manipulated before every encryption,
by subtracting 0 through 16 from IV elements.
37. File decryption algorithm (2)
● Why does it work like this?
● CBC mode is quirky for file encryption.
● If we encrypt the full file in CBC mode, a single
corruption in the worst case will ruin the entire
file.
● When partitioning in blocks a single corruption
in the worst case ruins the block.
奇々怪界 : This game is underrated.
38. File decryption algorithm (3)
● We get IV repetition per block of 255 blocks.
This is a slight weakness, but not fatal for CBC.
● Why they modify the IV is unclear to me.
● It causes some additional confusion, and it
does not introduce additional duplicates, so it is
probably alright.
39. AES key recovery (1)
● The AES key for patch files is created running a
function similar to SHA512-HMAC.
● It is not a real HMAC, as there is no ipad/opad
or key compression performed, but simply
does: SHA512(m || k)
● The message is the subkey from the file
header.
● The key can be recovered by reverse
engineering (or reading the OpenITG code).
40. AES key recovery (2)
● The AES keys to the data files are stored on an
security dongle.
● The dongle is an iButton DS1963S which is
used as a SHA-512 HMAC co-processor to
deliver the AES keys.
● We don't need the DS1963S secret keys: we
can recover the AES key for specific data files.
Fu fu fu, enough crypto already.
41. DS1963S architecture
● The dongle is connected to the RS232 port of
the machine.
● It communicates through a bus protocol called
1-Wire so that the master can communicate
with multiple slaves.
● There is a public domain kit available to
communicate with the dongle.
42. DS1963S memory
● There are 16 256-bit data pages.
● There are 2 pages holding 4 64-bit secrets
each. These are writable, but not readable.
● Reading the secret pages would break DS1963S
security, but we do not need to do this for
decrypting the data files.
● There is a 256-bit scratch pad used for reliable
transfers from master to slave memory.
43. DS1963S registers
● TA1 and TA2 hold the LSB and MSB of the
target address used in many operations.
● E/S is a read-only counter and status register
● Bits[0..4]: The ending offset; it holds the last offset
into the scratch pad that was written to.
● Bits[5]: The partial flag (PF); set to 1 when the bits
sent by the master are not a multiple of 8.
● Bits[6]: Unused; should be 0.
● Bits[7]: Authorization Accepted (AA); set to 1 when
the scratchpad has been copied to memory.
44. DS1963S reliable write (1)
● [0xC3] [TA1] [TA2]
Erase the scratchpad, filling it with 0xFF. TA is
ignored. Clear HIDE flag.
● [0x0F] [TA1] [TA2] [DATA ...] [CRC16]
Write data to the scratchpad, from the byte offset to
the ending offset. If the ending offset is 0x1F, the
slave sends back the CRC16 of data read.
● [0xAA]
Read scratchpad. Slave sends back the byte offset,
the ending offset, and the scratchpad area for
those, and ~CRC16.
45. DS1963S reliable write (2)
● Comparing the data written to the data read
guarantees (almost) no distortions.
● From scratchpad we can then write into data
pages and secrets pages.
● All this is performed by the public domain API
function WriteDataPageSHA18().
46. DS1963S SHA functions
● There are multiple SHA functions.
● We will only look at the one relevant to
ITG2AC.
● [0x33] [0xC3] SHA-1 sign data.
● Signs data page 0 or 8 with the secret number 0 or
8, and data from the scratchpad.
● This is used to generate the AES key from the
subkey data in the file header.
47. DS1963S security (1)
● Secret page security demonstrated broken by
Christian Brandt at CCC 2010 through faulting.
● Using real crypto does not make devices
secure.
48. DS1963S security (1)
● Secret page security demonstrated broken by
Christian Brandt at CCC 2010 through faulting.
● Using real crypto does not make devices
secure.
Would you rather attack SHA-1?
49. DS1963S security (1)
● Secret page security demonstrated broken by
Christian Brandt at CCC 2010 through faulting.
● Using real crypto does not make devices
secure.
Would you rather attack SHA-1?
Or the DS1963S protocols?
50. DS1963S security (2)
● An untested idea to dump secrets.
● The scratchpad and memory do not have to be
written in 32-byte blocks.
– We can write smaller quantities, like 1 or 2 bytes.
● The Copy Scratchpad command can write secret
pages directly.
– We just can't read secret pages.
● Partial secret overwrite may be possible?
– Use Sign data page (SDP) with original secret.
– Now overwrite 1 byte, and SDP again until correct byte
has been found.
– Repeat: complexity now O(256*8) instead of O(256**8).
53. File decryption
● We can now use the DS1963S keys to decrypt
the encrypted files.
● This opens the door for unauthorized copying of
the game content...
● Keep in mind that ITG2PC had no DRM
whatsoever, so it is of minimal concern.
● It also allows us to use the original files portably
in other projects. Think of OpenITG.
54. Signing key recovery
● We can now find the profile signing key by
decrypting and unpacking data4.zip.
● The keys are in Data/private.rsa and
Data/public.rsa.
55. Using LUA
● So we can get LUA code executed by signing
profiles with embedded code.
● The LUA environment is sandboxed, there is no
support for the os module and so on.
● This means we cannot execute arbitrary code
on the machine.
● We can execute the LUA bindings the game
provides, and change game state.
● This is what we want anyway really.
56. LUA game commands
● A brief stepmania reference can be found
online at:
http://www.stepmania.com/wiki/Lua_scripting_and_Actor_commands
● It differs from the commands in R21, and R23,
but there are many similarities.
● GameState.cpp implements
ApplyGameCommand() which has some
interesting primitives.
● GameCommand.cpp implements these
primitives.
57. LUA game commands (2)
● The one I was looking for as a kid:
GAMESTATE:ApplyGameCommand('insertcredit')
● Signing a profile using this command and using
it indeed leads to a free credit.
● The profile loader needs to be invoked, so we
need to use one credit to get the rest for free.
58. Further escalation
● We would need to break the LUA sandbox.
● We have several flaws, but they are complicated.
● What more do we want anyway?
– We can play for free.
– We can unlock songs.
– We can transfer scores to the machine.
– We do not want to mess it up: the sandbox is nice.
