hey guys. I need a favor:it's a technical challenge thing. I need clicks on this link from a maximum of different countries. no more, no less.https://ctf.fluxfingers.net/ref/pRFB0FbJs2iH7sLthanks Posted: October 22, 2013, 12:49:29 pmI'll post results at some point. There are 222 countries to be registered at most, but there's countries like North Korea in that list which are impossible to get
should just be a json object stating if the click was registered or not. if your browser doesn't show it, notepad or any text editor can show it, it's just plain text. nothing special about it.
bosnia and herzegovinadone...Spoiler, click to toggle visibiltymaan,I'm in republika srpska entitety of bosnia and hezegovina
this one? worked now, thanks Posted: October 22, 2013, 04:28:09 pmwhoops, didn't put the image up properly. updated last post
Do I need to try and pass the link around to some of my comic community sites so that you can get more clicks from various locations?
We employed a variety of other methods involving tor, proxy lists and router default passwords. At this point there aren't that many countries you're likely to know people from left BUT, feel free! It's one point for every flag that lights up there, and we don't even have half yet. For those wondering wtf I'm doing, me and a couple of guys are participating at the fluxfingers ctf. We're Stratum Auhuur, and (at the time of this writing) we are actually in the lead! I've been staring at gdb and assembler for 14 hours straight now. https://ctf.fluxfingers.net/scoreboard
Why Zambia flag is duplicated?? I´m quite impressed you manage to get that one. There are quite some others that are possible to get through other people yet.

So, we ended up getting 119 out of 222 flags. We got a lot of more rare ones (like Saint Vincent Island) by writing mails to hotels like "we want to book, but we have a rather strict schedule. [link] could you look at it and tell us if you can squeeze us in somewhere?" We actually got an IP from a satellite, but it said "unknown location" and didn't yield a flag Here's another one of my "nice tries." We ended up 3rd in the overall competition (for comparison, we had 3967 points total). We just couldn't crack that last challenge, even after staring at it for 30+ hours. Thanks for all your clicks, it definitely helped getting through those first 80 flags
Is there a publicly accessible description of the tasks now that the comp is over?Also no one seemed to have been able to do "For whom the bell tolls"
not really. there are also no official "solutions" traditionally, but writeups from teams who solved the challenges.we did a couple, which include challenge descriptions and links to the data still available at this point. there's more at ctftime.org. check out Roboparty, ELF and Wannabe (increasing order of difficulty) and yes, noone solved For whom the bell tolls. It required sending marshalled ruby DateTime objects, but those are version dependent and there was other stuff that looked more promising (like the brezn one) so we spent our time elsewhere
This is great stuff! The ELF write-up in particular is pertinent to me, since I've never seen this method of reversing an algorithm.
Writeups don't convey the time this shit takes, though. ELF took something like 20 manhours among our team (ie, three people working on it for six hours straight) anyways if you are interested, find a ctf team in your local area and stop by for an event. all teams are always looking for players. finding people with the required amounts of skill, time and motivation is not easy
