I'd give credit where it's due, but this actually came from another server's forums. 1. Flyhacks Perhaps the most common hack, flyhacks enables a player to fly. You can find out by simply looking at them and seeing if there flying. 2. High Jump This hack allows you to jump up an extremely ridiculous height, and take no fall damage when landing. This is extremely noticeable when you see someone flying up in the air and dropping down again, and they repeatedly do this without a fight. 3. Water Walking Not as common as the hacks mentioned above, but a hack nonetheless. This, as it's name suggests, allows you to walk on water as if it is a solid block. This is very obvious when you see someone standing on water with none of his body submerged. 4. Derp Hacks This does not really give any PvP advantage, but it will make your head spin around like crazy, and the head can retract into the player's body and so it looks like the player has no head. A good way to show players that you are not derp hacking if you are spinning your mouse like crazy is to press W when doing so. It is not possible to walk in one straight line while spinning your mouse like crazy, but this hack negates this function, thus if someone is walking in one straight line while spinning his head madly, he is definitely derp hacking. 5. No Fall As its name suggests, this hack negates all fall damage. 6. Step This hack allows you to sprint up one block high structures like an enderman. It can be seen if a player walks up one block high stairs without any jumping motion. 7. Tracer Draws a line to from your cursor, to all nearby players. 8. Chest Ray By pressing a button, this allows you to detect chests a long distance away. This can be spotted when a player digs in a certain angle without placing torches and end up in a dungeon, stronghold or any chest. 9. Forcefield / Kill Aura Forcefield, also known as Kill Aura, is a common Minecraft PvP hack used by many players in order to gain an advantage over others by many blatant things. One of them is how Kill Aura/Forcefield (Let's call it Forcefield) hits players in your vicinity while you attempt to hit players. This locks onto many targets (mobs, hostile mobs, players) and can be seen while being hit when the opponent is not facing you. They will be able to at the same time hit multiple players, and have the ability to click very fast while it autoclicks. When Forcefielders hit you, you may find it difficult to hit them. This is because you get knocked back while trying to attack them, and you will end up dying most of the time. Strafing does not change the outcome. 10. Click Aimbot ClickAimbot is the same as Kill Aura, but it locks onto one mob/player/target while it hits very speedy. You can hit them, but it usually teeters back and forth to players by you, even teammates. Just like Forcefield, it's possible to hit while you don't face them, and this is very easy to spot. The hack is specified to swivel to the nearest player they are attacking to make it look like they don't hack, but if his/her's head swivels between players when you aren't facing them, then it will most likely be ClickAimbot. This is related to BowAimbot, which does the same but with a bow. 11. Sprint Assist Sprint Assist can either be from a client or a modification. Sprint Assist is a modification that lets you speed very fast while obstacles will be hit under you, including walls and blocks. The way this is a hack is the way it lets you run into blocks yet you keep on running. It automatically holds down sprint for you and this is illegal, unlike Toggle Shift. On occasions, you can see if they have sprint particles under their feet while they stand on a block. This is not the best way to determine a sprint assist, because Minecraft does that normally if you are lagging or it's just there for no reason, as a graphical glitch. This hack is common. 12. Speed Assist Speed Assist is a hack known as "Speed" which lets you run very fast, as if you had a speed potion. Some hacks for Speed let you run at faster paces, as if you had Speed II or Speed III. If they do not have a speed effect and are still moving fast, you may report them. Some move slightly faster, but some move crazy fast. Speed hacks can be found while using flyhacks, or spider hacks, to not be seen or to do the job faster. This is usually caught by MAC. 13. Bow Aimbot BowAimbot gives you an advantage to shoot enemies from far away. However, it does detect teammates and it will still shoot them regardless. Just like ClickAimbot, BowAimbot lets you swivel back and forth to people while aiming at someone. Almost all of the shots using BowAimbot are accurate, however they can be dodged. It's not possible to detect BowAimbot from far away, as they may have good aim. BowAimbot is a pretty uncommon hack due to it being so easily identified at close ranges. 14. X-Ray X-Ray is a cheat that allows you to look through the ground as if it was glass, but transparent. There are many different versions, but Xray lets you see chests, ores, players, and misc. valuables that can't be seen without it. There are customizable hacks that let you customize what you see, and Xray hacks can leave tunnels which can be easy to spot. If you see an xrayer, report anything you think needs staff's attention. There are also several resource packs which serves a similar function, but does not have a toggling ability. The most common way to identify an X-Ray hack/modification is by looking for coordinates on the top left. The X-Ray hack adds in the coordinates to the top left corner of the HUD which is shown there without pressing F3. 15. Nuker What is does is that it creates a massive hole of a large diameter, causing players within that radius to fall in unless they are flying. It also breaks the blocks instantly, and the crater is very massive and must be reported on sight. 17. Reach Hacks This hack used to exist. It does not exist anymore, and is a common hack accusation. What this hack does is that it extends the player's reach till it is the same reach as creative mode, and can be spotted when a player places a block/ breaks a block out of normal reach distance. 18. Autocrit Turns all your hits critical, without falling or jumping. It can be caught if a player appears to land critical hits when just standing still or just walking or running, without any jumping motion. 19. Spider Hacks Allows you to climb up walls as if there is a ladder, when there is not. This can be identified by a player nametag glitching into the wall, while the player is climbing. 20. Fast Shooter Hacks This is a deadly hack mechanism which has been brought back to life by several new hacked clients. What this hack does is that it allows a bow to be fired at such high speeds, the entire wall/floor is literally covered with hundreds to thousands of arrows within several seconds. Some hacked clients even have the ability to make every single arrow fired with this hack become fully charged arrows, which proves deadly in Super Paint Ball as the gun will act like a bow. 21. Anti-Knockback Very common in PVP related things, this hack disabled you from being knocked back, even with a Knockback II Enchantment. However, in bacon brawl there is glitch where the player may not get any knockback so it may be difficult to know if the player is using the hack or not. 22. Regen Hacks This is also commonly used in PvP related things or anything that involves you getting hurt. This hack allows the player to boost there regeneration speed so that they can instantly keep health to max. To know if someone is hacking just check their hits.
