Bitcoin Forum

I like to delve into bitcoin history a lot. as we all know there've been a ton of crypto exchanges that have been hacked, but i'm really struggling to think of any gambling sites that have been hacked. maybe I haven't been paying enough attention.

does anyone know how many there've been? they seem like obvious targets to me with masses of coins flowing through them.

what are they doing differently compared to exchanges? i'll guess plenty of exchanges are inside jobs. does this mean gambling site operators are incentivized to be more honest in general too?

They have been hack jobs performed on numerous bitcoin casinos but they would rather not disclose this to public as it is bad for business but they get out to the media from the ones that have been comprised.
Not necessarily bitcoins have been stolen but users emails and passwords for their accounts.
The last big one that I can remember was Cloudbet that happened late last year.
I think it was just customer email accounts and players passwords but I could be wrong. :-\

Don't know about the history of gaming sites that have been hacked, but just as I do with exchanges, I never keep more funds than I need on a gambling site, just in case the site does get hacked or decides to abscond with player funds.

I don't know how many gambling sites have been hacked. As far as I know there was news last year about that but what I remember is just there is a strange text window that pop up on gambling sites with affiliate tag. Sometimes that pop up give codes for third-party gambling sites that would catch the attention of a gambler to try. Then maybe that's the start of users being hacked (not sure though but it might be).

of course no one should be keeping their money on gambling websites, a lot of gambling websites go bust and they run away with all the money deposited

It seems like gambling sites have actually put more effort into security in comparison to exchanges.  The ratio of gambling sites being hacked or going down has been FAR less than exchanges.

I don't know about that but I know many exchange sites are hacked than gambling sites, it's a fact that is easy to understand because many gambling sites be a scam if they are not serious about doing business.

Actually gambling sites have rigging problems due to some bugs which causes exploitation. As far as I know it happens very rare to see some gambling sites being hacked like exchanges are being these days. It seems that exchanges are more vulnerable because of traffic and large number of available funds which attracts attention of hackers.

Recently,Primcedice was sort of hacked by one of their testers.He manipulated the data on their test server I guess.Not sure if that counts but yeah he won 100+ bitcoins by playing and was only found after Stunna investigated the matter.You can check the thread here : https://bitcointalk.org/index.php?topic=1546299.0

Do you have any sources of this happening this year at all?

I used to warn people of sites doing that but not seen any site doing that since DaDice and dicebitco.in and dice.ninja before that being the 2 largest sites that closed and ran away.

I think it happens less now since players would rather stick to the longest running and most trusted sites like Betking.io

Gambling sites like to keep most of their money in offline wallets, they need only fraction of their wallet in hot wallets.

On the other hand, exchanges for some reasons don't use them.

Here's some read:
https://news.bitcoin.com/bitfinex-us-regulation-cold-storage/

Very often, the network gets the information about that hack into a server and people lose data or money. This is not good.

If no one will disclose then this is bad for the customers like us. This should be known to everyone so that we could avoid those sites that have been hacked. Security is a big must in the cryptosphere. Any lax security in any site should be patched and fixed.

there wasn't a ton of exchanges hacked, there was only 2-4 exchanges which were hacked but the amounts were big.
you don't hear about the casino hacks in big news like bitfinex hack because the casino bankroll is never as big as exchange (120KBTC). but it happens all the time.
the smaller sites get hacked all the time even small exploits in their code that leads to someone winning a lot by using that.
even primedice has been the target, i don't remember the exact amount but i think someone used a bug to steel hundreds of bitcoin from them.

Yes, PrimeDice has been exploited before, but it wasn't really a "hack", more of a clever exploitation. It was done by a user called "hufflepuff" and is probably the biggest Bitcoin heist ever made on a gambling site.

You can read the full details here: https://bitcointalk.org/index.php?topic=843892.0

I think there are multiple reasons you haven't heard much about gambling sites being hacked compared to exchanges:

1. The total amount of coins on there is generally much lower than in exchanges. If hacks occur, the maximum the hacker could run with is lower, making it less of a target and less newsworthy.

2. Because of the lower volume, there are also less requests for withdrawels. This allows easer manual checks and gives higher security for withdrawels. In addition, because of the lower number of withdrawels, the hot wallets can be smaller as well, leaving yet again a smaller target for the hackers.

The only hacked casino i knew recently was rollin.io some user abused their site by winning every roll he does. The site went down for a few days after that then recovered right away.
Here's the post about that incident : https://bitcointalk.org/index.php?topic=687571.msg13673745#msg13673745

Only rollin disclose this one they had been hacked but it's exploited by some players, primedice is prime example of this where some players made a lot of money to find the some bugs, recently a players turn dust into very big amount but stunna discovered this one.

You have to ask yourself how many of these 'hacks' are genuine & how many are the site owners scamming.

I'm not mentioning any site specifically but I'm sure you can see what I mean.

I remember PD getting exploited not hacked by hufflepaff as some people already mentioned. DaDice was also exploited when existed and magicdice as well. Rollin.io was also exploited once for ~3BTC if I remember correctly.

I do not know, I just play a really reliable, but I feel I have a lot of sites that end with a reason like that. I guess a lot of sites that do not want to pay members and argued that its website hacked, but there are also some sites that really hacked, well it's just my opinion, but it may have been many things as it happened

I will still lay the blame on these merchants who are solely responsible fir the safety of investors funds as they care to spend more on firewalls to make them non-vulnerable to attacks from hackers because they are being paid for the service they are offering and they should be held liable until then we are still waiting for another big bang because hackers will continue to hack... My opinion though...

Yup, why Gambling sites will put more effort into security, Because they will invest a lot to create their site. And once they lost repute in the market, Then no player will choose that site. But in exchanges, if we compare to Gambling sites the security is very less. That is why Gambling site is better than exchanges.

I didn't heard about this any gambling got hacked as like exchanges going down because of getting hack, even some gambling getting exploited by some genius player who discovered the system to cheat the casino and make a lot of money by using this tricks, gambling sites spending a lot of money to make secure their system.

since there are many sites for gambling with high sequirity against hacking or doss attact but the hackers always hack that sites which they want .
but hack of gambling site is usually not a work of hacker . it may be the admin's mind fraud ( i had listen about this in a artical blog of google)
but reality may be any thing .
last time the sites was hacked was cloudbet .

I don't have an idea too of how many gambling sites that have been hacked or if there is any of them. And I know that their security to their funds are very secured and it is not going to be penetrated easily unless one of their staff is going to do back job for the gambling company they are working for it.

I think most gambling sites actually do keep the majority of their coins in proper cold storage as opposed to in a hot wallet on their servers.
Haven't heard of too many gambling sites being hacked.

Since i have been started work with bitcoins, i never hear about hacking any sites specially gambling, except Bitfinex. I think you are asking about hacked sites because of Bitfinex, Otherwise i am playing gambling a lot but i have trust on all sites, also i don't think that it would be happened in future.   

thats true, they need to have some money safe in order not to lose everything by a mistake, in my opinion not a lot of them were hacked

the gambling sites is one of the favourite sites for hacker, the security for player wallets is very strong, i havent heard any single attack announce to public, i dont know whether they keep it closed or no one ever being hacked, the one that i know is hacker prefer to hack the system like the one happened in Primedice last time

I also havent heard ever since i have been using bitcoin that any of the bitcoin gambling site have been hacked.Bitfinex is an exchange not a gambling site similarily Mtgox got away but thats also exchange.I also gamble on fiat gambling site but never heard anyone being hacked.

Only one that comes to mind is PrimeDice. Apparently some player found some exploit and used it to make off with a few coins. There have been other website which exploits also.

I also didn't hear about something similar. Casinos probably pay a lot for a protection, and they are much safer then not licensed exchangers. Not just bitcoin casinos, also casinos for other currencies hasn't been hacked. Maybe even if that happen they keep it in secret and give their money to cover it up. Better to lose little money on that, then to ruin all business.
In real world banks and other firms with lot of money, pay good money for security, guards, protecting systems. On internet is the same situation, who pay more for protection, and organize better system will be much safer.

What is totally strange for me that I don't hear about  obvious casino hacking incidents but we hear all the time about exchanges being targeted and funds stolen in a process.
So my question is - either hackers don't care about casinos or they really have amazing security...

actually that is entirely right. exchanges put a lot more effort in their security. but their hack is more important and always a lot bigger so everybody hears about it and will remember it but when a gambling site gets hacked nobody cares and it is not big enough to get into the news.

for example exchanges hack is 120KBTC but a gambling site hack is 50-100BTC at most!

I don't think there is a lot of gambling sites have been hacked, because usually this sites have high level of security against DDOS attacks and so, so not easy for hackers to steal them

i think you are mistaking DDoS attack with something else.
i suggest you read about it here: https://en.wikipedia.org/wiki/Denial-of-service_attack
it is not directly related to the hacks.

and gambling sites get hacked a lot actually, these can be smaller hacks like some small time hacker exploiting a bug in their system (it happened with primedice and many other dice sites that i remember) and win a big amount and withdraw immediately before the owner finds out and patches it.

Protection of the casinos and the gambling sites is really high and the owners of this sites pay huge amount for such security usually, that's why i think there is no many gambling sites have been hacked.

That is for sure, why you are going to create a gambling site or business that is just going to be easy get hacked. I think a single hacker is not able to hack the security and system of a gambling site for just them to be able to get the funds of the site. But maybe if they are a group well they have a chance, but as of now there is no news about it.

Gambling sites are not worth for hackers to use energies since amount is lower. Some sites have been exploited due to some unknown bugs in script. I have heard once or twice hardly about exploitation issues but hacking didn't come in my knowledge so far. Exchanges are always at risk since they flow large amount of money in hot wallets as well.

Everything is in interest of hackers, if they managed to quickly find some vulnerabilities, the reason why we don't see much hacks of casinos is because they keep most of their Bitcoin offline. Exploits are more serious threat to them, but they can always make checks before paying to some suspicious winners. Also, in case of exploits players money should be technically safe, only investors risk.

True, no one would intend or do to store  their money  on a gambling site because  most of us for sure when we  win on a gambling game we directly  withdraw it without any hesitations. I do only heard on exchanger sites that are being hacked but  in gambling  sites i didnt heard such one news.

Why anyone wants to hack gambling sites , where you will get nothing much, ya it may be that they hack the gambling site to get the next result of the casino, or mess up with the bets and try to win with his bets. But then also i think it will get caught. Gambling sites are with more security and their only peoples lose their bitcoins. So gambling site wont get hacked.

I agree, bitcoin exchanges are susceptible to get hacked and loss so many btc which bad to price that would be fall down and it's get into hot news that discussed by everyone. Gambling sites also get hacked like Primedice loss BTC100 and others gambling sites that maybe get hacked but not become a hot news because it's not exposed which bad for the business.

I was reading an article about casinos doing ddos attacks on their competition
in order to damage their rep. It was a Korean site but I know its also happened
with a few sites in Australia.

I have never heard any casino sites being hacked, if attacked by user with ddos, yes there are several sites being attacked and cause the site to stop working, but if being hack then the money being stolen i think it hasnt ever happen yet, or maybe the sites has a great way to cover it, because losing money because of hacker is going to destroy the site reputation

Once upon a time hundreds of news sites were shouting something like this "Primedice Bitcoin Gambling Site Hacked for $1M". But technically it was more exploiting rather than hacking. Never heard about actual hacking of a gambling site. I think that's because of two things: first their security is strong and second you won't get much money even if you hack them.

It was online article you read? If yes, then please share it with us. I would like to read about it.

---

One more thing  to consider is fact that even if some casino were hacked in the past - and they managed to recover without taking too much damage.
They most likely won't share hacking incident publicly. It would only cause them more harm than good, because their reputation will be tarnished.
So this is actually one more fact I found interesting and it explains why bitcoin casinos are rarely hacked.

What has come into my knowledge is about exploitation and ddos attacks or phishing attempts issue with gambling sites. It is possible as some friends raised point that may be it happened in past with some casino and they didn't leak the news to cover their reputation. I didn't hear not that some site where I was playing had hacking problem because never encounter any issue not even with withdrawals.

True, because they may keep all their money in some other safe wallets, not in the hot wallet. If you hack their hot wallet, you may get very less money and that much money loss will not impact to any big casino houses. If you want to hack those big casino then one should first know where they park all those money and that is not so easy to any hackers.

In general, the site should never keep more than 5% of the total balance in the hot wallet. However there is a lot of maintaince because every few hours that wallet might want to get refilled.

Maybe those site really doesn't bother to invest on high security features since they doesn't aware for those hacking issue will provably hit on their site, but nowadays i don't really see some of gambling site's crying for their lose from hacking maybe they learned some lesson from the past experience of those sites happened to be hack so they do proper checking nowadays so they can cover up those possible loophole for hackers to access their site.

yes it's true rather than hack gambling sites i think the hackers will choose for hack bitcoin or altcoins exchange especially for big exchange because there are a lot of money at there besides gambling sites and i personally very rarely to heard that any particular gambling sites got hacked and maybe you were right that hack gambling sites is not worth for their effort

Gambling sites have good strategy to keep some limited amount available for immediate withdrawals and rest keep safe away. What I have seen hackers go for thousand of Bitcoins. I heard always in hundred of thousand and millions have been stolen by hackers. Gambling sites are good because they are working in low profile.I don't think some gambling sites has faced some major issue in this regard so far.

I think in exchanging site or any about is it has a high profile security that the ordinary cant penetrate on it . the choose gambling because they saw a loophole in their system so that it can be hack if the exchange has a low security that that would be a big profits to the hackers.

Recently I heard about rollin which had been exploited and that is very common issue for gambling sites, we had so many examples like that but I never heard any gambling site got hacked as per my personal knowledge, because gambling site providing more better security and that is the reason they are running successful business.

I haven't heard for sure or the authenticity of rollin. But I am sure if indeed any gambling sites don't provide good security then it would be a golden opportunity for hackers doing the action, because most hackers do the action security gaps of each site.

I haven't heard yet of hacking of gambling sites and to be stolen a lot of user funds there. Well almost all major casinos keep very few of their total funds in their hot wallet to pay users and more than 85% of funds is kept securely in cold storage. I think this is the reason why gambling sites hacked are almost non existent while in exchanges if people keep a lot of money for trading and exchanging then hacking can happen as they are keeping the majority of the funds in hot wallets for ease of use. One exception is Yobit which we all know very often their online hot wallet is empty and they need to charge it to pay users in their signature. Thats why we never heard of hacking of Yobit so far.

Yeah, it's very rare (or never) for us to heard about gambling sites got hacked since hackers looking for a big amount to hacked like in exchangers hot wallets, and gambling sites playing so safe with just put the big amount of bitcoin in cold storage.

the same for me, i heard several exchanges but never a gambling websites, they just sometimes run away with people money

Yup it's one of the easiest ways for owners of exchange to stealing customer money I do not think gambling sites have a higher level of security
I think all use the same security system oddly exchange sites are always experiencing theft of funds. maybe there should be an institution that oversees the exchange's website is certainly not government institutions.

Well just so you know, gambling sites are one of the websites that has the highest security especially those who are already in the business for a long time.

And they are more investing to security because that is the one that is going to make them bankrupt if they are not going to invest with it.

They are just being hacked when an hacker studied their website for a long time and sees some flaws to their system and security.

I don't know but until right now i never heard about that even there I think that are just the way for run with the money.

It is indeed very true that now there is no news that says there is no gambling sites that are compromised. But I think that it's because they provide excellent security for any gambling sites owned, hopefully it can be done properly in order not to do hacking

Yup, till today I am also not heard this type of news. Hacking casino sites are not easy, and they will provide very high profile security to open their account. So yes suppose some casino owners may take all players money and run, but hacking and looting house money is not possible.

Exchanges take much more security measures, yet they are hacked more often than gambling sites. Why? Because gambling sites store most of their bankroll on cold wallets, so it's just impossible to steal from them. Also, gambling sites are much simpler than exchanges, so there is less room for exploits.

there were a lot of gambling games that "got hacked" to be honest though they just turned to a scam and thats it they stole peoples money

I don't know how many exactly the gambling sites that have been hacked. As far as i know there many gambling sites are been hacked by those hackers and i think that is the same people who hacked every sites. There are so many hackers nowadays not only gambling sites are being hacked also atm accounts.

Hackers are everywhere not only on this online world there are lots of thieves and bad people will do anything just for the sake of money.I cant remember on how many already gambling sites are being hacked since theres no statistics or list showing previous hacked sites that's why we should really be keen on putting up our money on gambling sites,

if about gambling site, iam never hear about hacked
if crypto exchanger iam hear poloniex(2013 or 2014) is hakced and bitfinex in 2016
maybe is not popular gambling site and low wager is been hacked and possibly directly scam so all people can get information about hack

I am.in the bitcoin world from 3 years but still I have not yet heard that any Gambling site got hack . And also I didn't hear wether any gambling site steal bitcoin of any user by without spamming the user .
Here few of the sites got hacked of exchange ( special meaning is of ETH theft ) but still  didn't hacked any casino .
And second thing that I know Gambling sites have big security of Thier bitcoin so I don't think any benefit to hack any gambling site .

I agree, bitcoins casinos are rarely hacked and there is no point because most of them don't have a significant amount of funds in their hot wallets. Most of the bitcoins they have are in cold storages and mostlikely it is not even linked to the servers. So there is really little point in hacking it.

Hackers usually hack for financial gain, but have also done so for political or purely malicious reasons.  Personally,  I haven't heard yet about hacking in gambling ,but if there's, this is frequently done with the aid of software, which embeds into a victim’s server and records all keystrokes that occur, allowing its user to gain access to password-protected areas of the victim’s site.

Even if they get hacked how are you going to be able to compile all the list ? There are rumors of hack but I doubt if their target is a gambling website because it's not resourced like other financial institutions.

The thing is, gambling sites attract a lot of money so obviously, it will always be a favorite target for greedy hackers. And i'm sure a lot of gambling sites have already been hacked before and will still be hacked in the future. Where there's money to be stolen, expect these hard working hackers to have their noses on it.

The only one that I could think of that was "hacked" was Dicebitco.in, Of course, This hack was pretty much doubted by everyone considering the style the website went down with. Other than that, no website went offline because of a hack in the recent months that I could remember (a big one, at least), PD was cheated for thousands of coins, but through a betting exploit not through hacking and emptying of wallets.

The news came regarding this topic, but I did not find any information about this hacking. This is possible the hackers can hack any website. And yes the gambling sites are the first target for hackers because this is huge money one night they can become milliners. And now all sites are accepting only cryptocurrencies this is one advantage for hackers to hack gambling sites. They can easily exchange cryptocurrencies.

Gambling sites can really be hacked but as of now it wont really be easy for them since most gambling site do store their funds on cold wallet which they do only put up small amounts of money on their bankroll. They do tighten their security since people or gambler would definitely see first gambling sites security before tending to play. If they saw a site have been hacked recently then trust of people will surely be decreased.

i believe people always want to get some bitcoin with simple way,gambling,investing or also hacking,but in my opinion,its only several gambling site that have been hacked,some of they only pretend being hacked,but truly they want to close their site and being scam,this is simple way for earn a lot of bitcoins.

Not many of them which is actually surprising, of course allot of 1-2 days old websites using that free and full of exploit script get hacked, but other than that the big websites rarely report hacks, either because they can afford to cover it or because they have good security preventing hacks completely.

Yes specially dice sites, because they have a common pattern on how they run and if someone can find a hole in the script they can destroy almost all the sites.

But there are chances that the site was never hacked and the owner pretended to get hacked to run off with your money. The best way to avoid this is that you gamble only on those gambling sites whose office address and the gambling license and all the documents are transparent and listed online.

not really true , remember when primedice got exploited and lost thousands bitcoin?
they have grown as a big and trustworthy bitcoin gambling site but still get exploited.
there is nothing guarantee that the bigger site the more security they have , also online gambling always lack of trust.

Yes we had some major hacks in some of the dice sites in the past but now we are not hearing these exploits is because they will be actively monitor users who have usual rolling patterns and people who are winning a big amount and every big withdrawal is manual in almost all of the sites ,so it reduces these sort of incidents we had in the past.

When events like that happens, the casino owners become more attentive and set stronger defense mechanisms on their sites. It's good as a guarantee for gamblers and especially for investors who put thousands of dollars in Bitcoins on these sites. But I believe nothing is already enough when we talk about safety, samehow the defense mechanisms are upgraded, the hackers upgrade their attack mechanisms as well.

One of the most important thing on a certain gambling site is on its security which players can say that their money is safe even though they would deposit large amounts they will really feel secure and thats an important matter because most gamblers will seek out this for sure. Anything can really be hacked but depend on the skills of a hacker which we should still always be aware on this kind of risk.

Seems like everybody wants to start a gambling website lately using the available scripts.

I keep warning them and would personally never deposit any coins to a site like that. Either they get hacked or they run when they pocket a few bitcoins..

To be honest, I really don't know how many has been hack. I'm much interested on how many has been hack for real. The most popular hack was on PD when one player exploited it and got away with 1000btc+. I was there watching his insane betting and it was a real hack.

actually we should know about how strong the site security it is before make any huge deposit. bitdice so far has the strongest security in term of protecting user's account to get hacked, don't know about the site vulnerability itself , some experts might could explain a little about this. gambling site with huge bankroll and large community always been targeted to hack , so they might have prepared about that too.

I do not know, I guess only a little, and it was not hacked completely, but only bitcoin or coin theft on the site. Well, hackers may not be interested in picking up his site, but they are interested in the content that is on the site.

many of us don't know how many gambling sites have been hacked because if one gambling sites is hacked, the owner will not make any panic situations for the members. i think the owner will say that they have got a problem with the sites and the site will be maintenance for a while. but i think in out there, there are any gambling sites that will telling into the public if their sites have been hacked and all of the fund is still secure.

We may say like that but there are hacking that actually takes place. But then, why would you open a gambling site if you cannot afford your losses caused by your own mistakes ?

I mean does a gambler asks the gambling site for refund when he looses because of his mistake ? NO .. then why a gambling site has the power to stole balance of gamblers who were not even aware of the hack and the loop hole.

No idea either on how many gambling sites have been hacked. I guess most of them have tight security and they are empowering it so that their funds won't be robbed by hackers. This business is serious and I'm sure that no casino will start with a weak security for their operation.

There are probably quite a lot of casino's that are operated by incompetent owners/developers, just look at the sheer number of casino's that are listed here on the forum.
Then look at how they've built their website, some are really terrible.

It wouldn't surprise me if some of them had some pretty major security holes.

You're probably right, but still we don't hear much about bitcoin casinos getting hacked, and this is kinda strange, because money should attract hackers, and even small casinos have $50,000 - $100,000 worth of Bitcoin in their bankrolls. My explanation is that all (or almost all) casinos keep most of their bankroll in cold storage, and since it's not connected to the Internet, it's just impossible to steal from it.

You are right the best excuse to scam others is pretend to be hacked yourself and that's what most sites do because in case someone catches them up too, they can simply tell that they have been hacked.

While this happens there are some true cases of hacking too, like primedice was hacked by some hufflepuff and the best part of the scamming was, he was seen live winning. The good deed from PD was they never charged their gamblers for their own loss.

I'm still interested in the question that several gambling games were hacked, and What caused the reason and somehow was interested in this. The fact is that the owners and administration may have managed to heaven. This is a gold mine for people who profit from gambling. As they say, a gambler leaves coins. But if you collect a lot for each coin,

I agree it is a matter of security.  Even if the Casino gambling site is new as  long as their site is well secured and run by competent programmers, I believe they are hard to hack by hackers.  I also agree that even the largest gambling site can be hacked if someone find a glitch and exploit them.  Most of this glitch happen during updates and upgrades and during the installation of new games.  Though some gambling site use this hack as an excuse for their exit strategy.

Also it is smart if they do not have so much money in their hot wallets. Having cold wallets is one of the best things a gambling site could do to secure their site. There are still new sites who are ignorant with this fact as they are risking the whole deposit of everyone in their site as well as their bank roll.

Instead of the entire site being hacked, what usually happens is they find an exploit in the site and use it to their advantage and withdraw funds.

No Bitcoin sites will agry that they have being hacked, they will always try to cover their tracks. but tons of Bitcoin sites have being hack oh.

Not always a hack is real, sometime gambling sites claim that they have been hacked just to rip off investors of their money. Only some strong vault gambling sites may try to hide hack records just to keep the trust of investors.
