BlackFrog to Take up BlueFrog's Flag

Posted by Zonk on Fri May 26, 2006 08:56 AM
from the internet-routes-around-stupidity dept.
Runefox writes "ZDNet UK has a story about a new SPAM defense mechanism called BlackFrog, a response to the demise of Blue Security's BlueFrog. According to the article, the new service is based on a P2P network of clients, called the 'Frognet', which allows the opt-out service to continue functioning even after a server has gone down, making a DDoS attack like that which crippled BlueFrog ineffective against the new service."

bblboy54 writes "According to The Washington Post, Blue Security has closed its doors, which can be confirmed by the Blue Security application failing to work today and their domain no longer resolving. Blue Security's CEO is quoted in the article: "It's clear to us that [quitting] would be the only thing to prevent a full-scale cyber-war that we just don't have the authority to start," Reshef said. "Our users never signed up for this kind of thing." You have to wonder where it goes from here. It seems an effective method has been found but more than a small private company could handle. Will someone else adapt this concept, or does the internet world give up?"

    • That's the whole point of an analysis before sending opt-out messages from all members. I am not familiar with Black Frog intended function, but if a certain percentage of their members gets similar messages it's a fair bet it is spam. A FrogHerder must look at the message to ensure it is sufficently spammy, before action - this may even be legal somewhere in the world.

          With a certain threshold of participants required before the attack even takes place. If there are 100 members, perhaps 20 would need to agree on the item in question being spam. 15 wouldn't be enough to initiate a retaliatory opt-out.

          I wonder how much of the "background" noise on the internet is this sort of crap floating around....DNS requests for viruses, port scanning for viruses, traffic in the form of spam, spam responses, systems to deal with spam....probably more than anyone realizes.

    I thought the reason Blue Security closed shop was because the spammers had diff'd their user database, identified quite a large amount of the participants, and then threatened virus attacks directed at them. Not because of the DDoS.

    The spammer also sent another message: Cease operations or Blue Security customers will soon find themselves targeted with virus-filled attacks.

        • Frankly, they should have let the spammers go for it then. If you give in to Terrorists, you can only expect more terror in the future. Or so all the western governments seem to keep telling us as they send in the special forces.

          If the spammer took out a public enough target, the authorities would have had to get involved. BlueSecurity wasn't doing anything illegal (or even immoral - they only filled in the webform once for each email a user received.) so its a pity they were hounded out.
  • From their wiki:-

    Okopipi will automatically click the "opt-out" or "unsubscribe" links contained within the emails and/or report the spam to the appropriate authorities.

    I thought that it was generally a bad idea to click unsub or opt-out links in Spam messages since it only server to prove they have a valid email address and the receipient actually reads Spam messages.
    • Well, if you are trying to find spammers, and get more excuses to slam their websites, etc. then you want to click the unsubscribe links. The more spam they send you, the more they get slammed in response. Also, if this Black Frog stuff keeps track of this stuff, as part of the system, you then collect evidence of them sending you stuff even after you unsubscribed, which could be used to prosecute them in court as well as pounding their servers into the ground.

      So it makes sense for a system like this to

    • A legitimate concern, but with the Blue Frog system at least, the way this was handled was that the system did not identify which email address was clicking the links. All the "clicking" was done by the Blue Security servers, it just added up to one opt-out/unsubscribe click per spam message sent.
      • If the links are put together by someone who is not a total fucking moron, the link either has the email address encoded within it, or it is a unique token that links to a specific email address. Either way, following the opt-out link will indeed confirm that the address was deliverable. Unless these guys are just generating web traffic to the same server but a wholly different URL, preferably not even accessing the server by name but by IP... Which I doubt.

    Ok folks, let get a few things straight.

    Blue Frog was NOT effective not as a denial of service attack or distributed denial of service attack. It was never meant or designed to be. The Russian spammer said it himself - they never brought down our servers, they only served as "a daily nuisance". The nuisance was this: for every spam that the spammer sent to the some 500,000 Blue Frog members, an automated script (bot) visited the website advertised and filled out the form for snakeoil, home refinancing -- whatever was being hawked. But instead of filling it in with valid input from someone interested in what the website was hawking, it filled it in with a legitimate plea from a single person to Opt-out of being spammed further. With me so far?

    The spammer -- or worse, the spammer's client -- in turn, goes to check on their database of people or leads to which they can hawk their snakeoil and generic viagra and low and behold, instead of being filled with legitimate contacts of people they can do business with -- it's filled with hundreds upon thousands of opt-out requests.

    Undoubtedly there are real requests from potential business contacts in there. But first they have to filter out all the opt-out requests that Blue Frog has submitted.

    Sound familiar? It sure does. It's what we've been putting up with for years. We open our Inbox and instead of seeing email from friends and business associates, we first have to sift through and filter a few gazillion pieces of spam -- each with "Hi How are you?" and "Important Account Information" fake titles. Only then can we get down to the email that's actually sent to us. It's a nuisance.

    Blue Frog forced spammers to deal with the SAME NUISANCE they cause us. And the spammers didn't care for it too much. They don't care about opt-out requests, the Internet, what people think of them, possible prosecution --- all they care about is making money and they're making it by the truckload. The fact that Blue Frog actually bothered them enough to use their botnets to attack is VERY encouraging. It means we've found a way to kick them in the ass and make it hurt.

    Please don't compare Blue Frog or Black Frog to a DDOS or DOS. As the Russian Spammer demonstrated with his attack, what little network disturbance Blue or Black Frog causes for the spammer or spammer client server pales in comparison to a real attack. Mainly because it isn't meant to be an attack in the first place.

    If Black Frog ends up with 1,000,000 subscribers, then lets talk DDOS.

    This does look promising (from TFA:)

    "It will be based on a P2P network (the frognet)," according to a posting on the wiki. "On failure to connect it could still opt out given email addresses."

    Participants will send reports of spam emails to Okopipi, which will use "handlers", including dedicated servers, to analyse it. To avoid suffering the same fate as Blue Security, Okopipi's staff will not disclose information about its servers.

    "Only the Okopipi administrators will know their locations," the group said on its wiki. This should make a DDoS attack "very difficult", it said.

    That seems solid, but I wonder how something so open can keep a secret like what and where its servers are. It's beyond me, anyone have more info?

  • Disclaimer: This is my personal opinion and does not reflect the viewpoints of other members of the Okopipi project.
    --

    Sheesh people! I hate to have to respond to 1,000 comments made by kneejerks who don't even RTFA, saying how terrible it's to DDOS and how the system could be abused.

    Do you think we're idiots to let something like this happen?

    1. The "attacks" on websites will be moderated. We want to make sure that the force is non-lethal to websites. We haven't discussed the implementations, but the decision has been taken: We will use throttling to PREVENT denial-of-service attacks.

    2. The P2P network does *NOT* control the clients, it'll only distribute opt-out scripts for websites. Also, the customer can log out ANY TIME they want. So, NO, it's NOT a botnet.

    3. Spammers Don't need P2P networks to initiate an attack. They already have their effective botnets in infected WinXP machines.

    4. There will be a reputation system AND a hierarchy system (so not everyone can mod someone down), people will have to earn their trust to classify scripts, those who report wrong sites will be modded down, and the usernames and reputations are permanent. The hierarchy system we're studying requires at least two people acting as an individual before taking any action, to prevent infiltrations.

    5. We're already considering infiltration of spammers in our model, we're researching papers written by experts in graph theory and computer science for this. A spammer could at most try to disable the network, but with the currently planned infrastructure, i doubt they can do it.

    6. We haven't started to code. We're still discussing (and will continue to discuss) the possible consequences, abuses, attacks and how to prevent them or at least minimize them. We cannot afford to have ANY point of failure.

    7. If any wants to cooperate, the google group is open to ideas.

    8. And I repeat: we will *NOT* DDOS websites. It's a decision the commitee has taken, and it's a final decision. There have been people who have proposed to DDOS the spammers to death, and we're already shutting them up.
  • Due to TradeMark conflict, I have closed the Black Frog project. Actually the project was just a nameholder, since Okopipi was a separate project which I joined later.

    So the official name of the P2P antispam software is now "Okopipi". Please stop naming it "Black Frog" or we could get sued for Trademark Infringement.

    Thank you.
