Hacking

Hacking. Because sometimes you need to get places you shouldn't be, get items you don't have access to, or even be a hero and disarm a bomb. Hacking is a vital skill for the Engineering department, and is often useful to many others too.

Not to be confused with e-magging. Please check out E-maggable objects for all E-maggable objects in the game.

Tools of the Trade

Insulated Gloves - Stop you getting shocked.

File:Screwdriver2.gif Screwdriver - A necessary tool, used to expose the hackable interface on many devices.

Wirecutters - A necessary tool, used for 'Permanent' hacking. Is also much easier to get than the Multitool.

Multitool - A better tool, used for shorter, safer hacking. Often harder to get, however.

Crowbar - A brute-force tool, for opening depowered airlocks and other such tasks.

Keep an eye out for:

Budget Insulated Gloves- Budget versions of the insulated gloves. More common in Maint, can be bought from hacked tool vendors, but no guarantee of quality.

• 1 in 7 chance of Full Insulation, Shock Immunity.
• 4 in 7 chance of 50% Damage Decrease
• 1 in 7 chance of 25% Damage Decrease
• 1 in 7 chance of 50% Damage Increase

Fake Insulated Gloves - Sometimes found in maint, sometimes made by jokers using washing machines and crayons, these gloves probably offer zero insulation. On close inspection (Examine), "They don't feel like rubber".

A beginner's guide to Airlock Hacking

You're new to the Server, or SS13 in general? Wanting a basic rundown on how to get into areas you shouldn't be? Read here.

A beginners guide

Important, before you begin:

• Whilst hacking in general is accepted by server rules, deliberately shocking half the station as a non-antag will get you in trouble.
• This also goes for hacking into secure areas and taking High-Risk Items - if you're not an antag, don't do it.
• Hacking into places you shouldn't be is at least Breaking and Entering. Even public areas might be considered Damage to Station Assets. If security are having a slow shift, expect them to come after you.
• If Engineering over-charge the station grid, the shocks delivered can become lethal. Proceed with preparation, or at your own risk.

What do I need?

Insulated Gloves - Shocks hurt. If possible, you want real insulated gloves. If not, you can roll the dice with Budget Gloves, or find a pair of Latex gloves for a minor insulation. If none of this is to your taste, you probably want to have a Burn patch from medbay ready, or suit sensors on in case you get shocked to death.

File:Screwdriver2.gif Screwdriver - Absolutely vital, to open airlock hatches. You can usually find one in Primary Tool Storage, Auxiliary Tool Storage, Maintenance, or ask Cargo to print you one.

Wirecutters / Multitool - Multi is better if you can get one but if not wirecutters will do. Try asking Cargo for a multitool, but don't be surprised if they say no. Wirecutters, however can be found in the same places as screwdrivers. Just be aware they incur a minor risk of shock when used to hack.

Crowbar - To open the door when you're done. Again, found in the same places as Screwdrivers.

Practice, learning the wires

First, pick an airlock nobody will mind you breaking. Little rooms in maintenance, public toilets are good choices. If you try to practice on the Captain's door, expect a smack from security.

Use your screwdriver on your door to open its wiring hatch, then click on the door with Wirecutters or Multitool in hand. This should open an interface with a list of wires. These are randomized every round, but the same for all airlocks in each game. If you have a Multitool in hand, you want to press 'Pulse' for each wire, and watch for any changes. If Wirecutters, you want to be Cutting.

Each wire you Pulse / Cut might do something (see the wiring table below for detailed information), but the two you want to be looking for for now are Main Power (aka Test) and Bolts. If all the indicator lights on the hacking interface go out (you will see "The Test light is Off!" at the bottom of the hacking window) chances are you've hit Main Power. Write this down, or memorize it, as you'll be needing it when you go against real doors.

If you hear a click and the airlock's red bolt lights turn on, this is bolts. Memorize it, another useful one. If you've been using Wirecutters, be aware that you cannot reverse this. Be careful not to trap yourself.

Finally, if the door starts continually sparking and delivers a massive shock to you, you've hit shock. Go find a new door to continue testing, as this one will be broken for 30 seconds (multitool) or until Engineering come fix it (wirecutters). You can test if a door is still shocked by throwing a metallic object (such as a screwdriver) against it.

Real targets

So now you know Test and Bolts. When you come up across a door you need to bypass, Screwdriver the Panel open then Pulse / Cut the known power wire. The door is now offline for ten seconds. Use your Crowbar to force it open (then Cut / Pulse Bolts to lock it there if you'll need to make a getaway), and proceed in. Congratulations, you're now a basic door hacker.

Major Hackables

The main things you'll be hacking into. These often have multiple wires, the ability to shock you, or other fun side-effects. Caution, and insulated gloves, are advised.

Airlocks

How to:

1. Use a File:Screwdriver2.gif Screwdriver to open the maintenance panel.
2. (If Plasteel Secured) Use Wirecutters to cut the electrified grille. Insulated Gloves required!
3. (If Plasteel Secured) Use a Welding Tool to cut the outer armor.
4. (If Plasteel Secured) Use a Crowbar to remove the outer armor.
5. (If Plasteel or Metal Secured) Use a Welding Tool to cut the inner armor.
6. (If Plasteel Secured) Use a Crowbar to remove the inner armor.
7. Hack using a Multitool or Wirecutters.
8. Use a File:Screwdriver2.gif Screwdriver to close the maintenance panel when done.

Syndicate Bomb

How to:

1. Check the Timer - If it's high, you can ask for a bomb suit. If its very low, reach minimum safe distance (or try not to be gibbed).
2. Use a File:Screwdriver2.gif Screwdriver to expose the wiring.
3. Hack using a Multitool or Wirecutters.
4. Good luck

Cutting the bomb wires carries a 2 in 5 chance of detonation. Pulsing only 1 in 5 - although you will need to cut the Activate wire when you've found it. Either way, be careful, and listen for messages after each wire you tamper with.

Wire	Effects	Pulsing	Cutting	Mending	Finding the Wire
Boom	The Big-Bad. You do not want to hit this wire.	Detonate.	Detonate. An Inactive bomb will be defused.	N/A	If you're pulsing an active bomb, and suddenly you're dead, you found this wire!
Activate	The wire you need to cut to Disarm the Bomb!	An Inactive bomb will begin countdown. An Active bomb "seems to hesitate for a moment" on first pulse (+10s timer) On further pulses, "Nothing Happens."	DISARM. You win!	N/A	Pulse each wire in turn. Provided you don't get unlucky and hit Boom, your bomb will eventually seem to hesitate for a moment - this is your cue. Cut this wire, hero.
Unbolt	Controls the bolts locking the Bomb in place.	Displays message, "The bolts spin in place for a moment".	Will remove the anchoring bolts if deployed.	N/A	Pulse each wire in turn until you get the message about the bolts.
Proceed	Will hasten the end.	Displays message, "The bomb buzzes ominously!" If the timer is over 60s, timer reduces by 60. If the timer is over 20, timer reduces by 10. If the timer is between 10 and 20, timer is set to 10 seconds. No effect if timer is under 10 seconds.	Detonate.	N/A	Pulse wires. If your timer suddenly accelerates, you've found Proceed. Do NOT cut it!
Delay	Will hold off the end.	Displays message, "The Bomb chirps.". First pulse increases timer by 30 seconds. Further pulses have no effect.	No Effect	N/A	Pulse wires. If the timer increases, you've hit Delay.

Nuclear Bomb

The Redsuits have done it. The Nuclear bomb is armed and ticking. But is this the end?

Decoupling the Nuke.

1. Firstly, check how long the timer is left on the nuke. You may need to get out of there.
2. With welder in hand, weld the nuke.
3. Now, use your crowbar to pry it out.
4. Use your welder to weld it some more!
5. Wrench it to loosen some bolts.
6. Lastly crowbar, the nuke should move after this! Pull it into space, push it out of the station sector, and maybe save the day.

Disarming the nuke.

1. Insert the Nuclear Authentication Device and unlock the Nuke.
2. Apply a crowbar and remove the panel.
3. Use your wirecutters on the device and pick a random wire. Be aware you have a one in seven chance of disarming the nuke. You also, however, have a one in seven chance of setting the nuke off instantly.

Good luck.

Minor Hackables

There are many minor items that also can be hacked, although you rarely have need to do so. For completeness sake, we have included the Safe in this section.

Fire alarm

Fire alarms on getting cut will not detect or activate the fire doors in the case of a fire or a breach.

Security Gasmask

Using a screwdriver on a Security Gasmask will change the lines it uses. A wirecutter will break the gasmasks hailer, causing it to switch to a set of lines permanently. An emag will cause the hailer to spout a long string of curse words.

Radio & Signaler

1. Screwdriver in hand, click on the offending radio so it can be modified or attached
2. The usual radio use panel will pop up, but now with access to the wiring. If you've closed it by accident, just click on the radio as if you were going to change the settings on it.
3. There are three wires. Two have apparent uses; the third is pretty much useless.
   • Output wire will disengage the speakers (or signal-receiving on a signaler)
   • Input wire will permanently disengage the microphone (or signal-sending on a signaler)

Interestingly, tracking beacons and station intercoms also count as radios.

Secure Briefcase & Secure Safe

1. Screwdriver in hand, click on the (briefcase/safe) to open the panel and expose the wiring
2. Multi-tool-spam the (briefcase/safe) until you get a confirmation that the memory is reset.
3. The memory is now reset. Punch in your favorite code and hit E to set it.
4. Screwdriver the panel shut.

Smartfridge

Much like Vending Machines:

• Pulsing the orange light will electrify the fridge for half a minute.
• Setting the red light to blink will make the fridge shoot items at people.
• Changing the purple light to yellow will remove the permission lock on the fridge.

File:Safe.jpg Safes

Although not technically Hacking, we're still breaking into something. You are here because you need something locked up in that stupid indestructible metal box. Either for something very dangerous, or just because you have a good reason.

1. Hold stethoscope in one hand, interact with safe using an empty hand.
2. Spin the dial to the right until you hear an -unk (it can be klunk, krunk, plunk etc), then keep spinning right.
3. Stop spinning to the right when you hear a "Klink", "Tink", or "Plink" (not to be confused with "Clink").
4. Spin to the left, you shouldn't be hearing anything, keep spinning and you will eventually hear again, except instead of "clacks" you will hear constant "tink" "prink" "clink". You're almost there.
5. Stop spinning when you hear a "Spring", "Sprang", "Sproing", "Clunk", or "Krunk" It will show up as a big bolded word, hard to miss.
6. Open the safe.

Cargo Computer

Want access to a few illegal items, but don't have an emag?

1. Deconstruct the Cargo Computer console
2. Use a Multitool on the control board
3. Rebuild the computer

Simple as that! You should now have the option to buy a couple of naughty crates. Be aware, however, that much of this is class C or even class S contraband, so security are within rights to put you all in jail for the rest of the round!

Tips and Strategies

Finally, a brief list of a few fun things you can do.

Airlock Deadlock

• Cut the bolts wire on an airlock. Now cut the Power wires. The door will be impossible to open until repaired. Now, cut all the wires (to make it less obvious which is which), use a sheet of Plasteel or Metal to reinforce the wires compartment (hiding the wires) then weld the whole airlock shut for good measure.

Remote Signal Devices

• You can attach remote signalers to wires which, when recieving their frequency, will act like a multitool. Place a signaller on the Bolts wire, and remotely lock someone in or out. Signaller on the shock wire, set the door sparking from a safe distance.

The Crusher

• Cut the Safety wire on a door. Manually close the door on someone. Repeatedly open and close the airlock, crushing them to death while they're stunned there. If you can knock someone down and get them into a crusher, you can kill them without ever owning a lethal weapon.
