Q & A
What is the 'randar' exploit in Minecraft?
-The 'randar' exploit is a powerful coordinate exploit that allows players to find the location of any player on any server in real time. It was discovered by exploiting a mistake in the game's code where all in-game events, including structure spawning and item drops, shared the same RNG (Random Number Generator). By breaking a block and analyzing the coordinates of the dropped item, a player can calculate the location of the most recently loaded chunk on a server, revealing the server's coordinates.
Who discovered the 'randar' exploit?
-The 'randar' exploit was discovered by a technical Minecraft player named KN Fox, who made the shocking discovery after stumbling upon a video about RNG manipulation in Minecraft.
When was the 'randar' exploit first discovered?
-The 'randar' exploit was first discovered in 2022 by KN Fox, although the mistake in the code that allowed for the exploit dates back to 2011.
How did the mistake leading to the 'randar' exploit occur?
-The mistake occurred when Minecraft's creator, Notch, was coding the spawn of Villages in a beta version of the game. He accidentally made all in-game events, including structure placement and item drops, share the same RNG, which should have been separated for security and unpredictability.
What is the significance of the 1.8 beta version in the history of the 'randar' exploit?
-The 1.8 beta version is significant because it is the version where the initial mistake that led to the 'randar' exploit was introduced. This mistake made all in-game events share the same RNG, which was the basis for the exploit's functionality.
How did the Anarchy Minecraft Community use the 'randar' exploit?
-The Anarchy Minecraft Community, particularly a group known as the Masons, weaponized the 'randar' exploit to exert control over servers. They used it to locate and steal from item shops, effectively putting many out of business, and amassing a large stockpile of items in their own system.
What was the impact of the 'randar' exploit on the 2b2t server?
-The 'randar' exploit had a significant impact on the 2b2t server. It allowed the Masons to track players in real time and execute large-scale heists, amassing over a billion items in their Gringo system. It also led to the Masons becoming a dominant force on the server, as they could locate and target any player or base at any time.
How did the Masons keep the 'randar' exploit a secret?
-The Masons kept the 'randar' exploit a secret by creating a persona named 'munmap', which they used to scout locations without revealing their association with the Masons. They also only shared the exploit's functionality with high-ranking members, ensuring that the true workings of the exploit remained known only to a select few.
What event led to the 'randar' exploit becoming less effective on the 2b2t server?
-The 'randar' exploit became less effective when the 2b2t server updated to the modern versions of Minecraft in August 2023. This update soft-patched the exploit, preventing real-time tracking of players. However, the Masons still had access to a list of every active base and stash from when the server was on version 1.12.
What was the ultimate outcome of the 'randar' exploit on the 2b2t server?
-The ultimate outcome was that the Masons managed to accumulate a massive stockpile of items, surpassing 1 billion in their Gringo system, which equated to tens of thousands of dollars in potential revenue. They also managed to put many item sellers out of business, and eventually started giving away items en masse.
What precautions can players and server owners take to protect against the 'randar' exploit?
-Players and server owners can take precautions such as updating to the latest version of Minecraft, which has soft-patched the exploit, and being vigilant about any unusual activity on the server. Additionally, server owners should consider implementing stricter rules and monitoring systems to prevent exploitation and griefing.
How does the discovery of the 'randar' exploit affect the perception of Minecraft's code?
-The discovery of the 'randar' exploit highlights that even after years of development and updates, there can still be hidden secrets and vulnerabilities within Minecraft's code. It serves as a reminder that continuous testing and vigilance are necessary to ensure the security and fairness of the game.

😀 The Discovery of the Randar Exploit in Minecraft
The video begins by revealing a powerful exploit in Minecraft that allows players to find anyone's location on any server in real time. This vulnerability, known as the Randar exploit, has been present for 13 years due to a line of code written by the game's creator, Notch, in 2011. The exploit was weaponized by a group of players from the Anarchy Minecraft Community, who used it to control multiple servers. The video also discusses ways to protect against this exploit and thanks Hunky Star Rail for sponsoring the video. The history of the exploit is traced back to a mistake made during the development of the adventure update in Minecraft, which led to a shared RNG for in-game events. This mistake was later exploited to predict and manipulate in-game events, including the location of item drops.
🔍 The Evolution and Weaponization of the Randar Exploit
The second paragraph delves into the evolution of the exploit after its initial discovery. It discusses how the exploit was initially seen as a novelty and how major advancements were not made for some time. However, in 2022, a technical Minecraft player named KN Fox discovered that the exploit could be used to create a powerful coordinate exploit by abusing the shared RNG. Fox's experiments led to the shocking discovery that the process could be reversed, allowing the calculation of the most recently loaded chunk on a server by analyzing the coordinates of a dropped item. This revelation meant that continuous block breaking could reveal which chunks were being loaded by other players, effectively allowing tracking of their locations. The exploit was found to be functional in every version of Minecraft from Beta 1.8 to 1.12. Despite the update aquatic supposedly fixing the RNG glitch, modern servers that had previously run version 1.12 and below remained vulnerable to the exploit through old packet logs.
🎮 KN Fox's Exploits in the Anarchy Minecraft Community
The third paragraph narrates KN Fox's decision to test the exploit's effectiveness in the Anarchy Minecraft Community, starting with smaller servers like 9b9 and eventually moving to larger ones like 2b2t, the oldest Anarchy server. Fox's use of the exploit led to a significant moment where he managed to locate one of the most secretive stashes on the server, surprising the influential group known as the Masons. The Masons, known for their own history with exploits, entered into a negotiation with Fox. They agreed to collaborate, improving and weaponizing the exploit while keeping it secret. The Masons, with the help of Fox, streamlined the exploit, creating a system that allowed real-time tracking of players and the creation of heatmaps covering vast areas of the server. This exploit gave them the ability to observe player behaviors and gather an extensive database of coordinates, notes, and screenshots, which they used for strategic gameplay.
🤫 The Covert Operations and Heists by the Masons
The fourth paragraph details the Masons' use of the Randar exploit for covert operations and heists on the 2b2t server. They created a persona named munmap, which they used to locate and steal from item shops while maintaining a clean image. The Masons operated munmap in such a way that it gained a reputation, leading to the community coining the term 'mmap exploit'. This served as a cover for the actual Randar exploit. The Masons used a secondary account for the actual theft, ensuring munmap remained untarnished. Their activities led to a significant disruption of item shops on the server. Despite a scare when a YouTuber demonstrated a method to crack RNG, the Masons continued their operations, amassing a huge stockpile of items. Eventually, they managed to put many item sellers out of business and even gave away items to the community. The Masons revealed the exploit after several months of successful operations.
🌟 The Legacy and Potential of the Randar Exploit
The final paragraph ponders the implications of the Randar exploit's discovery and the potential for other undiscovered secrets within Minecraft's code. It highlights the exploit's impact on the game and the servers it affected, emphasizing the exploit's power and longevity. The video ends on a note that encourages viewers to consider the depth and complexity of Minecraft's programming, suggesting that there may be more hidden exploits waiting to be found.

to honky star rail for sponsoring
today's video so breaking a block is all
it takes to find anyone on any server
why did it take over a decade to
discover this well to give you the full
picture we have to go back to the start
it all began with a simple
mistake on September 14th 2011 Minecraft
updated a beta version 1.8 also known as
the adventure update which is the first
time Villages were added to the game now
in order to spawn into a world these
structures utilized r RNG or a random
number generator think of it like
rolling dice RNG is used to determine
many things in Minecraft such as where
mobs spawn or where an item spawns when
dropped from a block those dice rolls
should be unpredictable that's how it's
supposed to work however when the game's
creator Notch was creating the code for
spawning Villages he accidentally did
something you really not supposed to do
let me show you structure placement and
in-game events like item drops should be
determined by different rngs as a
programmer you would want to keep these
things separated however Notch wrote the
code so that all events shared the same
RNG it may seem trivial but this single
mistake would eventually have major
consequences however at the time it went
completely unnoticed as more updates
released new structures were added to
the game and like Villages they all
shared the same RNG to spawn into the
world for 7 years this code remained
unchanged it wasn't until 2018 that
someone finally realized this Quirk on
April 15th 2018 a YouTuber named Amiga
uploaded a video where by loading
specific chunks then exiting and
reopening a Minecraft world they
successfully predicted where a line of
lightning strikes would occur since
lightning is supposed to be random this
is the first number known video evidence
of RNG manipulation in Minecraft it
didn't take long for others to start
building on this knowledge a few months
later the YouTuber Earth computer
released a video further discussing how
loading specific chunks could be used to
manipulate RNG working together both the
prototech and sitecraft Community made
more discoveries such as abusing RNG to
make insanely fast mob Farms but sadly
there was a catch to all of this these
experiments had occurred in version 1.12
but a few months prior mojen had
released a snapshot of version 1.13 the
update aquatic which ended up fixing the
issue of in-game events sharing RNG all
these major discoveries had happened
after the snapshot so it seems Mojang
had patched RNG sharing by complete
accident at this point RNG manipulation
was seen as a novelty in an outdated
version and most people moved on there
were no major advancements for some time
but that's the funny thing about
Minecraft a bug being patched means
nothing in the grand scheme of things
sometimes the right person in the right
place can make all the
difference a few years later in 2022 a
technical Minecraft player by the name
of KN Fox had been browsing videos on
YouTube and stumbled upon on one of the
RNG manipulation videos from 2018 after
watching it he realized that a
coordinate exploit could potentially be
possible by abusing the shared RNG being
a programmer himself he started doing
some experiments to prove it all of them
involving the shared RNG world. Rand in
the most recently loaded chunk of a
server a woodland Mansion structure will
try and spawn into the world it uses
world. Rand and do set seed to try and
pick a location before it even checks
the spawning criteria the game is
running this Woodland Mansion check
constantly every time a chunk is loaded
at the exact same time by mining a block
where the dropped item appears is
determined by asking world. Rand for X Y
and Z coordinates this world. Rand is
shared globally between all players
meaning that those random XYZ
coordinates
were actually determined by the location
of the most recent Woodland Mansion
check so the steps always happen in this
order and on a server this information
is actually sent to every player's game
client whenever they break a block well
KN Fox would go on to make a shocking
Discovery this entire process was
reversible by breaking a block and then
using a lot of math on the coordinates
of the dropped item you can walk back
backwards through the seed generation
algorithm and calculate the location of
the most recently loaded Chunk on a
server all because this information is
given to every player's client whenever
they break a block even if they weren't
the ones who loaded that chunk so if you
keep breaking blocks you can
continuously see which chunks are being
loaded by other players this was huge
not Fox tried the exploit in earlier
versions of Minecraft as well and found
it still worked you just had to change
which structure you were looking for
based on which one was the most recent
on the internal list this exploit worked
in every version going all the way back
to Beta 1.8 the same one where Notch
made that simple mistake with the RNG so
from beta all the way to 1.12 the
exploit was fully functional now you
would assume that since the update
aquatic fixed the RNG glitch that modern
servers would be safe but that is not
the case if they ever ran version 1.12
and Below they are vulnerable because if
someone on a server was logging packets
for example by using replay mod they
could use this exploit to analyze those
logs and see where other players were at
the time so if a base from back then is
still active on a server today it can be
found using old packet logs and all of
this was possible just by breaking a
block KN Fox had discovered one of the
most powerful coordinate exploits in
Minecraft history one that had been
hiding in plain sight for over a decade
and affected almost all Minecraft
servers in some capacity in order to
test its Effectiveness he turned his
attention to the Anarchy Community the
perfect place to use it without fear of
being banned plus many anarch servers at
this time were still on 1.12 where the
exploit was most effective he started
out on smaller servers such as 9b9 where
he would show up at bases randomly and
fine-tune the exploit behind the scenes
since visiting a base would usually end
in its destruction this was a rare case
of someone becoming a griefer for
scientific purposes he would go on to
name the exploit randar a combination of
world. r land and radar which is
effectively how it worked with the
randar exploit proving to be a success
on smaller servers it was time to try a
larger one in March of 2023 KN Fox
turned his attention to 2b2 T the oldest
Anarchy server in Minecraft a place that
was no stranger to coordinate exploits
over the years just minutes after
logging in KN Fox had already compiled a
list of coordinates what happened next
next is perhaps one of the largest
flexes I've ever seen on 2b2 T knowing
how powerful his exploit was Fox wanted
to use it on one of the server's most
infamous groups the spawn Masons on 2b2
T the Masons have their own history of
using exploits to become more powerful
in fact one of their members leer is
considered the Mastermind behind the
Noom exploit which actively tracked
players across the server in real time
and could view distant bases remotely at
one point the group had the largest
active base on the server and even to
this day maintain a decentralized
network of item stashes called grots Fox
managed to figure out where one of these
stashes was located and decided to show
up unannounced one of the Mason accounts
that was AFK at the stash picked up
Fox's username they were taken by
complete surprise how did this literal
random managed to find one of the most
secretive stashes on the server they
began to panic and the Mason higher-ups
quickly got into contact with him to try
and negotiate he introduced himself and
revealed that he had used an RNG exploit
to Target them specifically as he was
not an active 2b2 T player he decided to
share what he knew with the select few
of them by working together they could
improve the exploit and make it more
efficient they could weaponize it while
also keeping it a secret the Mason's
Leisure Bubba J and negative entropy
were able to streamline it behind the
scenes after some quick coding they were
looking at a site all too familiar
[Music]
players were once again being tracked in
real time allowing for the creation of
heat maps for instance this one that
covers a million blocks in each
Direction the Masons had an active
database of coordinates that grew to
over 90 million entries which included
notes screenshots and username
associations over the realtime heat map
the randar exploit allowed them to
observe many interesting player
behaviors for example take a look at
these rectangles that seem to be forming
all over the heat map these are not
glitches the Masons were observing AFK
accounts using elytra hacks to scan the
terrain in a massive pattern moving back
and forth every player could be observed
just like with Noom and to think all
this data could be acquired simply by
breaking blocks but on 2b2 t with this
much power naturally the question became
how to use it well the Masons had some
very specific Targets in mind the
group's leadership was not a fan of 2b2
T shops or players that would sell
in-game items for real world money in
their eyes the best way to put these
shops out of business was to steal from
their stashes this would also allow them
to add to their own massive stockpile of
items in the grot system but if one of
the Masons were caught stealing the
community would instantly know there was
an act of exploit and their cover would
be blown so instead they created a new
account with no ties to the group a
Persona that would quickly become known
server
wide the Masons created an account named
munmap which had no associations with
them any mason using munmap pretended to
be a simple base Hunter they never
griefed or stole items with this account
just to ensure that players wouldn't
abandon or self- grief their own bases
if a set of coordinates seemed to be
active munmap would be sent to
investigate all the Mason members
combined ended up traveling millions and
millions of blocks in just a few weeks
if the location was a base or stash and
they wanted to steal from it they had a
second account named 1248 test user that
they would use for the dirty work
instead because munmap would never do
something so evil like stealing
Minecraft items but word quickly began
to spread about munmap showing up at
different bases it got to the point that
the community came up with the phrase
mmap exploit the Masons actually played
into this meme as it was a good cover
for the actual randar exploit it was
also important to keep the true exploit
a secret so while coordinates would be
given to different Masons only the
higher ups knew how it actually worked
but as the group began plotting some
very ambitious heists they received
quite the scare on May 1st 2023 YouTuber
Matthew Bolan uploaded a video of a
redstone contraption that could
effectively crack RNG inside of vanilla
Minecraft it involved measuring which
direction TNT was randomly fired in this
proof of concept made the Masons worried
as they feared others could keep working
on this idea and they might discover the
randar exploit on their own but luckily
this did not happen and they were still
the only ones with knowledge of the
exploit but it still put pressure on
them to act they had put together a list
of all the item shops they wanted to hit
and one by one they paid each one a
visit with munmap followed by test user
shop owners began warning each other
that munmap was not just a simple base
Hunter and was somehow finding all of
their stash locations since the 2b2
community as a whole dislikes item shops
munmap started to be considered a hero
for months the Masons were successful in
using randar to secure more items but in
July of 2023 one of their own stashes
was stolen from a player named a magnum
found one of their gring got stashes and
began stealing as much much as they
could thanks to the exploit the Masons
were able to detect this was happening
after a skirmish they got into contact
with Magnum and struck a deal Magnum
could take half of the stash unopposed
as long as they didn't leak the
coordinates Magnum agreed but of course
it was a trick the Masons used randar to
track magnum's location to see where all
the items ended up a few weeks later a
group of Masons got together and staged
a massive Heist taking back everything
that was stolen plus interest in
situations like this randar was the
Ultimate Weapon there was nowhere on the
server to run or hide and it would
continue to be this way as long as tb2t
stayed in version
1.12 well in August of 2023 the server
did the unthinkable and actually updated
to the modern versions of Minecraft
which soft patched the exploit they
could no longer track players in real
time but they still had a list of every
single active base and stash the Masons
realized it wouldn't be long before item
shop owners started moving their stashes
to new chunks so they began working
quickly they would spend the next few
months hitting as many stashes as they
could at some point the gloves came off
and they would sometimes raid on their
personal accounts rather than mmap or
test user they would pull off a massive
Heist on Knox shop one of the largest
item selling operations on the server
the shop owners did their best to defend
but at the end of the day out of 6,000
double chests of shulkers
4,500 of them were stolen successfully
around this time a whistleblower
revealed that the Masons had been using
a coordinate exploit for months but they
couldn't explain how it worked the
community was growing wise to their
Antics but it was too late the Masons
still had everyone's coordinates and the
total item count in the Gringo system
had surpassed 1 billion based on what
item sellers were charging this meant
tens of thousands of dollars in
potential Revenue were sitting in their
system but of course they would never
sell they had managed to put many of the
item sellers out of business though a
few managed to survive with reduced
inventory the Masons now had so many
items that that they just started giving
them away around Christmas time using a
delivery system to gift people shulkers
after the holidays the Masons knew it
was finally time to reveal the truth to
the public about what this exploit
actually was leer had first told me
about randar back in August or around 8
months ago but I was asked to hold off
on making this video Until the Masons
could finish their heists prepare the
technical documentation and server
owners could be warned behind the scenes
of this video's release because remember
the randar exploit is still active on
all servers 1.12 and below and even if
you play on more modern versions someone
can use old packet data to find you
today if not Fox managed to discover an
exploit hiding in plain sight this
entire time imagine what other secrets
are still sitting in Minecraft's code
