nice speculation, but imo it would make them look more bad, if they turn down the reports, because it will come back to them (either via the publication like in this case, or just simply someone exploiting it). so while I don't have personal experience working with the facebook security team, but at least they have a dedicated channel for reporting security related bugs and even a bounty program. thats more than the 99% of the sites/companies offer. btw: someone mentioned that 500 bucks isn't worth the efforts, but imo the same people would tell the same about $1000, or $5000 even.

The main thing is that the security division at facebook probably runs the bug hunting page (as with everywhere else, which does make a decent bit of sense). And, if you spot bugs before they do, then that looks bad on them (internally at the company and externally to the world). So, it is not in their interest to openly acknowledge your bugs, especially by paying you cash money (not to mention, accounting is going to hate them if they see bucks leaving the company for any reason, instead of coming in). Not to forget, it is in their interest to downplay your bug to the rest of the company and the world (for those same reasons). If you're doing research /for your own interest/, I recommend maintaining full-disclosure. Embrace the bazaar and burn down the cathedral. If you're interested in making money, the smart route is through script kiddies or whoever (but realize, you'll probably need to go ahead and write a reliable exploit, to see any real cash). Script kiddies (and agents of various governments) often have tons of money to throw around to either bolster their own image (and eventually get arrested) or make money from your bug (especially if you're providing a reliable exploit). Not to mention, the actual damage that will be caused by the majority of these "black hats" is nothing compared to what those companies are going to have done, before they eventually crash. You could also monetize your security research by taking an administration, research or QA position. But, too often, you're only ensuring that you'll never be interested in any of the work that crosses your desk, ever again. You'll laugh, if you ever end up taking a "real job" doing security research, when you see heads getting butted between research teams and QA teams. Most security companies, for example, do not look at their own products (imagine at HP, QA teams for various products would be screaming their heads off at Tipping Point, if they went bug hunting in HP products - often when it's publicly disclosed, those research teams will *still* stay away from it, so the QA teams can tackle it and avoid the headache). It often feels like the first person to market a firewall/IDS/IPS/etc.. pulled off the greatest exploitation, of a security vulnerability (and the most common/reliable vulnerability, social engineering), of all time. In short, what your father didn't tell you is: If you're trying to make money, by doing *independent* security research, *shop around* for a buyer. (Describe the impact to the buyer, to receive a bid, before releasing anything beyond generic details. If they do not make a serious bid, take your ball and go home. If you have the right friends, or enough spare money, involve a lawyer.) And, most importantly, forget what any of these cunts try to tell you about morals or ethics. They're only pushing their point-of-view on you. It's best to, at least, consider all of the view points and make a decision on what works for you/matters to you/etc... None of these people, including myself, can tell you what is morally or ethically wrong. And, don't let them heap shame on you, ever. Releasing a remote root/system vulnerability (even if you include a reliable exploit) to full-disclosure, conspiring with a company/individual to keep secrets for X amount of time and selling an exploit to an anonymous bidder should add no more weight to your shoulders than you already carry. Just be sure that *you* are happy with your decision. - sedition On 10/31/2011 6:11 PM, xD 0x41 wrote:Oh hey, 3k is great! I saw that they just made it look abit cheap... no wrath but, it is still a MULTI billion now, dollar company, so they shoukld be trying to make SURE they can out bi ANY underground payers.. thats all i had to question. thanks for clearing it up, but sure, if theyre paying better now thats cool, i should have said to, it is atleast a step in the right direction :s Still, they ARE*** a mutil frigging million dollar company lol, so why wouldnt they give say, 1k minimum and make sure they get people more than interested but even fuzzing for bugs wich could potentially be in use already... this is something theyre not covering atall really with 500bux. It is tho, a start... cheers for clearing up theyre rce payout, wow, so they maybe read googles hall of fame and did it in accordance ? Maybe im wrong but.... this company, is not really the same thing as a google, and i guess a bug on this site, would be actually worth 5million pcs to anyone buying it... im just saying for them being so rish, they could do better, and definately, the comapnies who offer nothing, should get nothing back, simple, thats why blackhats sometimes are blackhats, they got rooted around tryin to help some pig headed company who makes millions yet will screw you around so badly, you do realise they tried to reproduce the bug YOU made even, in order to _NOT_ pay you shit. remeber that. But then again, your in theyre pocket now, and really CANT do shit now but say yes sir no sir two bags half fkn full sir. am i rite. cheers tho. FB still sux hairy ones.

I've lost the reference, but I think they paid about $3000 for one case. Perhaps an RCE? Anyway, your assumption is off.one remote code injection bug for FB in a security environment wich is not white, and may sell the bug for upto more than 5000,You can't compare whitehat vs. blackhat programs. In the latter, you cross moral and legal lines. Most people aren't willing to be such a dick. Perhaps you should reserve your wrath for companies that offer $fuckall for good bugs? :) Cheers Chrisbecause if a RCE or other was there, something wich was 'seadable' or wormable, then theyre bounty should be far higher, because that doesnt even match up to what many 0days would sell for. If someone had a rce for this and were to worm it, now thats a million dollar botnet... that would be for those who could make from it something and there is no shortage of spammers all to happy to take control of 2million or more pcs... Thats just one scenarion, in wich they could loose somuch data and info, and in exchange offer 500bux. What a slap in the face, FB should be ashamed of that price and bump it up atleast for more serious stuff. EXE attachment would be medium to high risk, they would be able to now patch it, after first they did not acknowledge, but also did not have the bounty also... only recently they have added this, with what, a crappy 500 bux, multi million dollar enterprises, wich are saved by these disclosures, and they are paying pittance. SHAME ON YOU FACEBOOK.COM , Shame... Welcome to the Shame-Files FB, your a disgrace to the good people who are helping you. Nice bug, and, atleast you worked with them to reproduce, you realise they would have gave you 0 $ if they had repoduced this, so again, shame on them for only acknowledging this when they failed at repruction. Theat 'bounty' page screams to me of the actual owners writing, and, I bet he even probably hand wrote that, because he is a TIGHT FTSTED pr**k , someone should put a /blackhat/ folder there, but then, its not worth the time :) (no bug payout rofl...) Notice also, D0S is not part of this, well then this would be funny if one were to find a 0dayer in FB (ala apache d0s byterange style) , well dont bother disclosing it , just run it on a loop from theyre own pages, afterall, whats the use to disclose such a shitty thing (yes this is true it is shitty but, is all cases same...) So summary is, Remote code injection or other, will get ya 500$ ,but, if you goto an UG blackhat site, you might get 5k and up :P xheers and again, thanks for being a good person and helping the citizens of FB, really tho, you have, probably saved me even, 20 removals from my sisters PC :P So, yes, I thank you and FD surely would thank you but, FB dont give adamn :PIf they have anyone on this list who is also in theyre secteam well, you really have a 'suck-ass' bounty, wich should be looked over, because seriously, what worth would be it to give you anything, when it is directly cheaper from wqebsites to buy it, and not have any disclosure atall. I guess this is something YOU need to ponder, not me, and im glad for that, and Im glad again, i dont use the shitty service, and never will. Enjoy, have a great day!
