Backdoor

Summary

After discovering that V called someone at the Academy's Crypto Department, Caine heads over to Crypto to investigate. He runs into his friend Neville Clark, who is talkative, if obfuscating. The Cube Hunters entice Nev into sharing more information by giving him a puzzle, designed by jbd, to solve. Nev takes the bait, and gives us a backdoor that leads to a gridded file system.

Dragging the commands onto the grid to create various configurations yields a series of log snippets. Some of the logs resemble the Perplex City Errorlogs that were found before the puzzle cards were released.

The interface can be accessed at the following URL:

http://events.perplexcity.com/gateway/commandinterface/index.html

As of 17:08, 3 July 2006 (PDT), the puzzle is still being worked on. Join us in #syzygy, or see the discussion on the Talk page or at Unforums.

Commands

Through the combined work of jalapenodude, pelrun, and jbd, #syzygy has determined that the commands appear to work as follows.

The program pointer starts with the highest command in the left-hand column. It moves through the grid one space at a time, as determined by the command in that space and which spaces have been used before.

Generally, the pointer moves in the following directions when it encounters each command. However, if the next square has already been "used", the next direction (listed in brackets) is attempted. If this square has already been used, then the next in the list will be tried, and so on and so on (although N.B. the list of these below is far from complete). Some exceptions to this may occur - possibly certain combinations of commands may not run this check?

mount - se
zone - west (north, east, northeast, ...)
switch - se (...) (''Are you sure, goes NE on config 5 below?'')
rotate - north (northeast, then in clockwise order?)
copy - south (...)
flush - south (southeast, ...)
pwrite - e (south, ...)
popen - east (south, ...)
pread - west (south, ...)

(This means the grids below are dependent on what commands were used to reach a particular square... But I'll leave it here for the time being -- Scribe.)

rotate does something different depending on where it is executed, but also (sometimes?) where it comes from. Here are some directions that occur:

 e  e  e  e  s
 s ne  n  n  s
 e  n ne  n  s
ne  n ne  n  s
ne  n ne  n  n

However, it is possible for r3c5 to go north if entered from the west, for example.

The same goes for zone:

e e e w s
s w w n n
e e e n w
n w w n n
n w w n n

End ends execution whenever it gets hit on a specific error message. It is very good for testing where the code is going. Cache seems to only work as an end point. Run can go anywhere that the program pointer isn't reaching.

A configuration is a set of commands placed on the grid so that the grid is valid and a log file is retrieved. The command path is the actual path that the pointer takes through the grid configuration. Different configurations may break down into the same command path.

Configurations and command paths start with ZO-MO, and usually end with either CACHE or FLUSH.

Full Command Path List

The first two numbers are the resulting configuration, the letter after is the variation, and the string is the command path, with each instruction cut to two letters in length. The list is alphabetized based on operation name, as a reference service. Please be sure to also place them above with their respective results, and to sort them in properly when added.

Command/File Mapping

Other than the linked commands, we also get these two errors...

unable: "Unable to access file" unread: "Unable to get read handle"

The number of times the zone, switch, and rotate commands appears in a command path determines which file is displayed.

Configurations with one zone command

		switch
		0	1	2	3	4
rotate
	1	master	TNI	Suspic.	Header	Ioniser
	2	unread	TNI	Yorke	NanoImg	Ioniser
	3	master	TNI	Suspic.	Header	Ioniser
	4	unread	TNI	Yorke	NanoImg	Ioniser

Configurations with two zone commands

		switch
		0	1	2	3	4
rotate
	1	Camera	Coffee	Noise Control	NanoImg	unread
	2	Camera	Coffee	Noise Control	NanoImg	Tajison
	3	Camera	Coffee	Noise Control	NanoImg	Battery
	4	Camera	Coffee	Noise Control	NanoImg	unread

Configurations with three zone commands

	1	Laser	Sphere	unable	Clock	MagReg
	2	unread	Sphere	unable	Clock	MagReg
	3	Laser	Sphere	unable	Clock	MagReg

Approached the Master today about begining on an updated and 
revised edition. V. pleased to discover he considers the idea 
warmly. He actually said, 'My ideas are in good hands with you, 
and you will of course receive full credit for the work.' 
Somehow I expected more of a struggle. V. gracious indeed. He's 
not quite the glory-hog SOME people have made him out to be, I 
guess.

To: 55321801 

FROM: MANSOOR H. 

Kiteway's programs are disrupting the entire department. Breeding hostility 
and distrust among amicable colleagues. The man doesn't belong here anymore, 
why can't he keep his damned pet projects in his own office? Crypto is mine 
now, not his. 

Well, here are the metrics to show he's not minding his own business. 

Number of times Kiteway has visited dept. offices this year: 78 

And in 268: 129 

And in 267: 23 

Dept. suspicion level on the Howe-Panntonin Index: 8.8 

And in 268: 7.3 

And in 267: 4.5 

Suspect the man has his own agenda and isn't sharing with the proper channels, 
for example me and you. Suspect he is subverting the time and resources of my 
faculty without consulting me ahead of time. Behaving as though he can't trust 
his own senior fellows. Ridiculous. How long must we put up with this childish 
rigmarole?

If he dies, you realise that's it. You can do what you like to me - I don't care about me. Someone in my block got beaten up the other night. He isn't a violent guy; he's a calligrapher. But he just got attacked well f ... nothing basically. Well I think it was random, but I don't think I believe in random any more. Was it you? Are you trying to scare me? You don't need to so just ... stop it. I did what you wanted anyway. Last night ... I worked until I was the only one left in the office. Must have been about 11 when this delivery guy turned up with a trolley full of boxes. And he did look a bit surprised to see me there. These two big boxes were for us, so I signed for them and went next door to grab Angelica so she could open the stores. Anyway, the boxes were really heavy, so the delivery guy wheeled the trolley into the stores and dropped them off there. Then I saw him slide one of our cases under the trolley; when he moved the trolley, it wasn't there anymore. It was quick but I'm sure he swiped something. Then he left, and Angelica locked the door. I would have followed him ... well, probably ... but Angelica started talking to me about my research and I couldn't just rush off. I saw him go to the end of the corridor ... to the elevator, and he hit the down button. There's only the basement under us, but I think there might be passageways for internal mail and things. I honestly don't know. And I'm not going down there in the middle of the night, so don't ask. No matter what you threaten me with. Ummm the delivery guy was about 6 foot, white, short dark hair. I haven't seen him before. Keep an eye out, will you?

So this is it. Can't say I'm not glad it's over but, well, one day maybe you can tell me what this was all about. I mean, I read the papers - police raids on subway stations - sounds like your kind of thing. We've had a few more deliveries come in since January, but still no sign of the mystery man. It's been a different courier each time, and they've - they've all looked pretty innocent. The Viendenbourg messages are still going backwards and forwards. I appreciate what you've done for my dad, but ... I've done my bit. That's it. That was the deal. You can go digging around in the tunnels if you like but don't expect me to do any more of your dirty work. You told me to stop, so I'm stopping. Don't ever tell my dad about this. Over and out.

Look this is getting seriously dodgy. Last week, Lucas completely cut me out of a meeting, and Mansoor has been ripping into my white paper and... I'm sure it's not professional, it's personal. They know what we're up to, I swear. No I don't, I don't know anything. I'm losing it. Please, I can't be that important. You could get someone else. The whole place is shutting down over Solstice. You...you could get someone to break in here and I don't know...isotope tag one of the packages and track it you probably do that all the time...what do you need me for? Well, happy holidays.

So you've got what you wanted. It's Thursday the, what ... 14th of July? And here's your report. I don't know what you're expecting to hear but ... I don't know what's going on; it might be nothing. I ... I could be getting completely paranoid as well. I mean with you lot snooping round I'm already on eggshells. <swallow> Camden keeps watching me across the office - pretty sure he doesn't trust me. I might be imagining it all I .. I dunno. Anyway, today I think I saw something odd. And it - and it might not be anything but if it keeps you happy here it is. We got this delivery - we get deliveries all the time, you know hardware upgrades and stuff, but there was an extra item. It wasn't on the manifest. I only noticed it cos I was nearest the door when it all arrived, so I ended up signing for it. So there was ... there was this packing case and, now I don't know what's in there. And it's locked in the stores now so I ... I can't get to it even if you want me to - it's about 5 feet high, 3 feet across and quite slim, like ... a painting or something. So is this an art-theft thing? Is that what you're after - some kind of fence operation? And if you told me what to look for I might have a better chance of helping. <tsk> Well - that's it. I'll ... I'll let you know if anything else happens.
