+Nazgul Posted November 18, 2004 Share Posted November 18, 2004 "Lab Namesake's Invention" may be the cyclotron, invented by E.O. Lawrence, who has two labs (Livermore and Berkeley) named after him. Quote Link to comment

+WAAS-up Posted November 18, 2004 Share Posted November 18, 2004 OK, I'll ask some dumb questions for the next stage: Based on my 20 minute knowledge of MD5 hashes I'm guessing we will have to guess to the Input (time, lat, long) too see if it calcuates the correct Hash value since they are one way. That is, there is no way to go from the hash value back to the input. Also does any one know of a Windows (GUI or command line) executable that will work with the data inputs we where provided? I saw dozens to hundreds of code samples and binaries but did not see one that jumped out as directly suitable in terms of: enter salt here, input plaintext, enter password, then calculate hash value. The inputs are fairly constrained in terms of valid values (i.e. HH:MM approx 1.4k possiblities -- less because of night equipment requirement) and coordinate ranges are safe to assume in bay area CA.

+atc Posted November 18, 2004 Share Posted November 18, 2004 The clue "Hungarian" could be Leo Szilard, one of the scientists that worked on the atom bomb. For this stage, it looks like we need to guess two parameters: the password and the required numbers (coordinates, etc). Then generate the hash and compare against the listed hash. Even if we get the password correctly, still need to guess the numbers. Writing a software to brute-force the numbers with a given password is one approach. If anyone is familiar with Windows programming, there is Wincrypt API which might have the needed functions. Quote Link to comment

+Nazgul Posted November 19, 2004 Share Posted November 19, 2004 Big Trees Park in Livermore... Or perhaps it should be known as "Big Mutant Trees park" since I found this while looking up the park online: "In Livermore's Big Trees Park, less than a mile from the Lab, plutonium was found in the top two inches of dirt... A Big Trees soil sample contained up to 1,000 times the plutonium that would normally be expected, according to CARE's last study. The Lab admits that it is the source of contamination." (That's still below EPA health concern levels.) Wear your lead undies just in case. Quote Link to comment
+atc Posted November 19, 2004 Share Posted November 19, 2004 Excellent crack, Jif! The coordinate doesn't seem to have any geocache within 1/2 mile, although there could be some puzzle caches nearby. May be we can install a webcam cache here to monitor any suspicious activities between now and the "meeting date" Quote Link to comment
+TeamJiffy Posted November 20, 2004 Share Posted November 20, 2004 Here's how getting past the MD5 worked... 1) Take the SALT that was specified... but as a BINARY NUMBER of 4-bytes, not an eight-character hex string. (i.e., translate it to binary representation) 2) Append, (with nothing in between them) the "password", and then the text string, using the formatting conventions specified in the note. 3) Input this as the "string" or "byte sequence" to be handled by the MD5 program. Because you have to input the binary string, it would not be possible to do this from a command line, or entering the stuff by hand on a web page. You need to be able to specify the "salt" in a binary, not ASCII, representation. After that, it was a simple brute force to get longitude (try all in 121 and 122 longitude), given the cyclotron answer, and latitude (try all in 37) given the TELLER answer... I actually tried every scientist in the memo, and had my program loop through all of them. The date I got from the clue, and the time of day was brute force again. I don't know an easy way to do this (an existing program to put the "salt" in exactly the right place), other than by modifying existing MD5 code from somewhere. -Jif Quote Link to comment

It could be an alarmist trick. After all I expect the plutonium levels in any given park to be zero, and a thousand times that is still nothing. It's safe! I looked for a Fizzy cache there last December (It was missing and later archived). Yeah, missing because it sprouted 17 green legs and crawled off by itself!

+Lamneth Posted November 20, 2004 Author Share Posted November 20, 2004 Great job guys! We're on the verge of rescuing the FTF! Bug from the grubby clutches of Venona. I'm not submitting an Event Cache listing. This gathering doesn't fall within the guidelines for an Event (and it's a clandestine operation anyway ). But don't worry; this Topic will remain open, so anyone who doesn't make it to the rendezvous will be filled in with all the details (eventually... and with lots of blacked-out text).

Yeah, Venona, the Soviet spy reincarnated set forth a number of secret communication tasks in a sort of online multi-puzzle/event cache. The meeting place is Big Trees Park in Livermore at 8:00 pm on December 3rd (03-12-200420:00 PST) to "hash" over the fun and games/ work in breaking all the codes and passwords. Pun intended.

It seems like the posting times are off (unless, for some reason they are showing a different time zone.) Posting to this forum on my phone is more of a pain than posting a log entry on a cache page.

+Green Achers Posted December 3, 2004 Share Posted December 3, 2004 (edited) Is SF2062's recent activity in any way related to the return of Venona? Sorry but SF2062 doesn't appear to have left any tracks. No forum posts, no pictures, no finds, no caches,... three travel bugs. I've seen more activity in an empty mortuary. Care to share?? BTW Marky, I found a trick to minimize the mobile web time... I change the URL to start looking at the forum at a given posting. As you know, each posted message is numbered and you can jump past older messages without waiting for the page (groups of 50 postings) to turn. This is the 189th post of this thread so the URL would be http://forums.Groundspeak.com/GC/index.php...ic=83776&st=189 Now, about SF2062's activity... You mean this activity?

+Woof! Posted December 4, 2004 Share Posted December 4, 2004 (edited) I left 2 hours and 15 minutes to get from SF to the drop point. My plans were foiled by a self-destruct attempt on the Bay Bridge. It took an hour and 15 minutes to go three miles, and I hadn't even gotten out of the city yet. I decided to retreat. Perhaps Venona was tipped about my attempts to join the counterintelligence group? I'm totally disappointed, having wasted 2:15 of my time in traffic, and for missing the great Venona adventure for a second time. I hope everyone is having fun without me.
