Dawood Good day I've invested bitcoins in a investment site which closed down in middle December I'm one of thousands of people who got scammed as the CEO of the company fled abroad at the beginning of December. How can I recover my bitcoins from them as the site still works? All deposits and withdrawals are deactivated. Good day. I trust you are well.
I need your help and guidance. I have been scammed out of money. All i have is this companies bitcoin wallet address. I need your help not only to take back what is mine but put an end to this scam company that probably has done this to many others. Is this company local or international?
There is is not much that I can do with reversing transaction since bitcoin by design does not allow you to do that. You may be able get your funds back through legal process by contacting higher authority. But first I need more information from you. Please setup private messaging for your account so we can chat privately here. Our chat will be end-to-end encrypted. Dawood no problem. Is it possible to send fake bitcoin to any bitcoin wallet for period of time??
Coz these ppl are holding my package hostage and i want them to just have the account reflect so they can deliver my package? Please help. But they will not confirm. These transactions are confirmed by multiple nodes. Even if one node lets it through, others won't. This vulnerability is also patched now. Can you fix it? I had removed the page. There's no setup required. Dawood Got it. Thank you so much.
Glad I could help. Dawood Could you explain more about how did you get P? I don't understand this point. These bitcoins remain held on trust for creditors while the company remains under bankruptcy protection. He was imprisoned until July , when he was released on bail. Gox remains under bankruptcy protection, with the case still being under investigation.
In addition, the litigation with CoinLab remains outstanding and distribution to creditors cannot occur until that lawsuit is settled. Gox hack. A number of online theories have been developed as to where the missing coins are. Some have suggested that Mt. Gox held more bitcoin than it in fact held. In respect of how the hacker was able to access the bitcoins that Mt. Gox held in cold storage, the theories range from suggestions that the storage may have been compromised by an individual with on-site access to suggestions that the cold storage coins were gradually deposited into the Mt.
Gox exchange system when a hot wallet ran low, and that a lack of accountability among staff simply meant that there was no awareness that the wallets were being drained by hackers. In July , a Russian national named Alexander Vinnik was arrested by US authorities in Greece and charged with playing a key role in the laundering of bitcoins stolen from Mt.
Vinnick is alleged to be associated with BTC-e, a well-established bitcoin exchange, which was raided by the FBI as part of the investigation. Investigations by Wizsec, a group of bitcoin security specialists, had identified Vinnik as the owner of the wallets into which the stolen bitcoins had been transferred, many of which were sold on BTC-e. Gox hack are finally coming together. Whether any of this will result in the recovery of all or any of the stolen bitcoins remains to be seen, but it does appear that we will have at least some clarity into the Mt.
Gox hack in the near future. In February of , TechCrunch reported that a movement called GoxRising was working to pursue an alternative to bankruptcy for Mt. The idea behind GoxRising is simple: instead of use the bankruptcy courts to hand over Mt. It would appear that GoxRising has been successful in its efforts, as Tokyo lawyer Nobuaki Kobayashi has been appointed by Japanese courts to handle the civil rehabilitation process.
This is good news for anyone who lost their assets in the Mt. Gox failure, as they will likely gain much more as a result of civil rehabilitation. Karpeles knows that if he ended up with most of the Mt. Gox stash, his life would be in limbo. First, he would face a barrage of civil suits from Mt. Gox creditors who had lost everything to him. Bitcoin prices are much higher today than they were in , which would just add insult to injury.
Also, jilted investors may not be satisfied with simply suing Karpeles. People have been killed for far, far less than what Karpeles would have done, if he ended up walking away with a massive pile of Bitcoins after everyone who trusted him got burned. Needless to say, the civil rehabilitation process seems like a winning idea for everyone involved, and it looks like it is moving forward.
Civil rehabilitation is still a time-consuming process, but it does look a lot better than bankruptcy! The pivot to civil rehabilitation is emblematic of how much different the crypto world is from the established financial system. Bankruptcy law was a terrible framework to address the failure of Mt. It is highly unlikely that Karpeles was actually planning to defraud people who were using Mt. Gox, and his life has been rough since the exchange went belly-up.
Now, it looks like there is a way forward that would get Karpeles out of his unenviable situation, and make sure anyone whose assets assets were frozen in got them back. The clear lesson to the crypto community is that there need to be better structures in place for when the worst happens, as it is absurd that people are still waiting to gain access to their property. Crypto assets lend themselves to decentralized networks. Despite that, the exchanges that offer the best prices and deepest liquidity are almost universally centralized.
Once an entity takes ownership over an asset, the potential for a Mt. Gox-esque scenario exists. Given the kind of laws that govern bankruptcy in the established financial system, the way cryptos are traded does appear to be less-than-perfect. There are decentralized exchanges that offer a wide range of trading services, but they are unlikely to be able to match centralized crypto exchanges, especially when it comes to inter-exchange interface. The ability to trade directly with other centralized crypto exchanges is a big advantage, and it is difficult to see how that could happen without custodianship.
Custodial issues are one of the biggest issues for institutional investors when it comes to cryptos. Far from being paranoid speculation, the Mt. Gox situation gives any money manager who is being pressured to invest in cryptos a terrible example that could scare anyone out of the sector. Unfortunately, the crypt world grew out of boot-strapped platforms and business structures that were never intended to appeal to the world of high-finance. Now that more people are interested in cryptos, these sub-par systems are holding back the industry in a big way.
There are many bitcoin exchanges operating at present, some of which are more reputable than others. Popular exchanges such as Coinbase and Binance are relatively transparent about their operations, as well as offering insured deposits, and are backed by reputable venture capitalists. However, they are also going to be the targets of the best hackers, who will be only too happy to exploit any security gaps. That does not mean that such exchanges are operating a hack or disreputable in any way.

This turned out to be a false alarm. Thankfully, Upbit promised to cover the losses. The stolen crypto has been on the move. Whoever took it has been moving it between wallets, although it is unclear what purpose this will serve. As of January , Upbit has completed a major security update after a brief suspension of services.
Based in Vietnam, VinDAX is a relatively small crypto exchange that mainly conducts token sales for relatively unknown blockchain projects. In response, VinDAX emailed the projects that had been impacted by the theft asking for funds. After noticing an error in its outgoing funds transfer system, Japanese exchange Bitpoint immediately suspended its services.
However, it was too late. Bitpoint has said that they will compensate their users , but have not released a time frame as to when that will happen. Luckily for users who lost their funds, Bitrue has reassured them that they will be fully repaid. While it is still unclear as to how exactly the hacker s gained access to user funds, the culprit s managed to access encrypted secret keys.
So far, GateHub has managed to make some progress in recovering the stolen funds. Despite the fact that we are now in , hackers still managed to use a phishing scam and malware to hack into Binance. As a result, Binance promised to increase its security , but users are understandably wary. It appears that customer data may have been stolen as well. In August , someone started sharing customer verification information from Binance on a Telegram channel. It has been alleged that this data was also taken during the hack, and that up to 60, users may be affected.
The North Korean hacking group Lazarus was responsible. The hackers created a legitimate looking fake company and convinced DragonEx employees to download malware onto their computers through Telegram and LinkedIn messages. DragonEx has taken full responsibility for the hack and will be issuing refunds to those who lost funds. The exchange is also working with the police to see if they can recover the stolen crypto.
This South Korean cryptocurrency exchange was the victim of a suspected insider job. It all started with a suspicious withdrawal, and the exchange immediately suspended all withdrawals on their platform, but it was too late. Who conducted the hack is still unknown, but since there is no evidence of outsider interference, many suspect that it was a Bithumb employee who stole the funds. Analysts were worried , especially since the exchange was down for maintenance, a typical post-hack response.
Despite assurances from CoinBene that nothing had happened, the exchange was down for a whole month. The hack also came on the heels of a report by Bitwise Asset Manager which accused Coinbene of wash trading to manipulate the crypto market. In a bizarre turn of events, Youbit formerly known as Yapizon rebranded months later as Coinbin. Having already faced two massive hacks, you would think that Coinbin would be extra careful.
However, this hack was an inside job. It appears that the former CEO of Youbit was still working at Coinbin, and was embezzling company funds. This employee allegedly had access to private keys and was able to siphon off funds from multiple accounts.
This is a slightly less conventional hack, because instead of stealing money the hackers just stole information. Coinmama is one of the largest cryptocurrency brokers with over a million active users. There appears to have been little fallout from this hack, as Coinmama informed users rapidly once they learned that user data was being leaked on the dark web.
To date, no cryptocurrency has been stolen. Unfortunately for Cryptopia, they suffered from another hack 15 days after the first one. That was the end of the New Zealand-based exchange — they are now going through the liquidation process. For over , active user accounts, there is no customer data beyond usernames and email addresses.
Given that most of the active users on Cryptopia were from outside New Zealand, more should have been done to enforce AML compliance measures. It all started with Cryptopia users having difficulty accessing their accounts, and it only went downhill from there. The company originally thought it was a technical issue, but later clarified on Twitter that it was a security breach. The exact amount stolen in the hack is still unknown.
Get yours today! Cotten was the only person who knew how to access the cold wallets belonging to the exchange. In December, while on his honeymoon in India, Cotten died and took any information on how to access the cold wallets to his grave. Six cold wallets were identified to belong to QuadrigaCX.
However, when investigators looked at the wallets, five of them had been emptied around April No one is really sure what has happened, and investigations are still ongoing. An initial request was denied, however a new one has been made by the lawyers representing those who lost their funds. There are also alleged ties to a shadow bank in Panama called Crypto Capital. Lawyers of the exchange suspect some of the funds that are missing may be stored in Crypto Capital and have asked any former QuadrigaCX users for their assistance on the matter.
As of January , the FBI is now involved. A victim specialist from the FBI has been reaching out to former users and directing them to a portal where they can obtain more information. This hack is still up for debate as many believe it was part of an exit scam.
MapleChange was a small, Canadian cryptocurrency exchange that began to see an uncommon spike in exchange activity starting in October. As a result, MapleChange announced it was closing its doors for good. What made people suspicious was the immediate removal of the MapleChange website, social media accounts, and Discord and Telegram channels. The lack of communication has led many to believe that there was no hack despite MapleChange insisting they were just taking a break to decide how to proceed.
Instead of deciding to pay anyone back, the crypto exchange gave what little they had left to the developers who had created the remaining coins. The internet is still divided as to whether or not the whole thing was a hack or just another scam. However, Zaif did file a criminal case with their local authorities , which makes it sound like they have an idea as to who did it. Despite the fact that Coinrail was a relatively small cryptocurrency exchange, it did a lot of business which drew the attention of hackers.
The exchange was hacked in as well and you will see them again on our list , with hackers making off with substantial amounts of Ripple. This hack appears to be orchestrated by a group of North Korean hackers known as the Lazarus Group , who have been responsible for a number of cryptocurrency hacks over the years. Luckily for Bithumb users, the exchange promised to pay back any stolen funds.
Bitcoin Gold was an offshoot of the original Bitcoin, which took a hard fork from Bitcoin as an attempt to decentralize ironic given that Bitcoin is already decentralized. This type of attack was thought to be rare, if not impossible, until the Bitcoin Gold incident. Using some complicated maneuvers, hackers put their Bitcoin Gold onto exchanges, traded them for other cryptocurrencies, then withdrew the amount. Taylor is a cryptocurrency trading app, that raised a successful initial coin offering ICO in order to get funding.
Unfortunately, not long after, hackers managed to gain access to a company device and took control of a password file. There were concerns that this was just another exit scam, but it appears that Taylor has slowly managed to rebuild. However, it seems like this one was an inside job. It seems they may have been onto something, as he was later arrested. While the owner, Francesco Firani, announced the hack, other Bitgrail employees denied it and said there was nothing wrong.
People are skeptical as to whether this was an actual hack , or an attempt at an exit scam. Coincheck was the leading exchange in Japan, but the hack showed how remarkably unsecure the platform was. The hackers managed to spread a virus through email that allowed them to steal private keys. After that it was remarkably easy, as Coincheck did not use smart contracts or multi-signatures, and all coins were stored in the same wallet. Remarkably, the cryptocurrency exchange is still in business.
It began offering full services again in November Although the hack was believed to have been carried out by North Korean hackers, the malware originated from Russian hacking groups. NiceHash is a cryptocurrency mining marketplace that allows miners to rent out their hash rate to others. Their payment system was compromised , causing the contents of users Bitcoin wallets to be stolen. Youbit formerly known as Yapizon was a relatively small South Korean cryptocurrency exchange that had experienced a hack earlier in This marked the end for Youbit, they filed for bankruptcy the same day.
Bithumb makes yet another appearance on this list. At the time of this hack, Bithumb was the fourth largest cryptocurrency exchange by volume worldwide. Not long after, users started to notice their accounts being drained. Before Yapizon changed their name to Youbit, they experienced their first hack. This Hong Kong-based cryptocurrency exchange had claimed to be the most secure exchange in the world. Unfortunately, that proved to be very untrue. The price of Bitcoin plunged as a result of the hack.
He added that Binance will be able to cover the bitcoin lost without help. The company does not know yet exactly how many users were affected. The company is currently working with other exchanges to block deposits from hacked addresses. He encouraged everyone to change their API keys and two-factor authentication. We will try to maintain very high transparency.
He added that the idea came from the bitcoin community. Further update: Binance CEO Zhao said the company will not pursue a rollback of the bitcoin blockchain. Considerations being:.

Gox operations for several days; manager who is being pressured to invest in cryptos a value store we have on our computers.Writes one security expert: “A lot of Russian bitcoin hackers have coded bots to automatically grab coins from vulnerable addresses.” Presumably. The bitcoin and cryptocurrency community, fiercely protective of its privacy, has been rocked by a massive data breach that's seen the personal. The issue of security has been a fundamental one for bitcoin since its development. On one hand, bitcoin itself is very difficult to hack, and that is largely due to the blockchain technology which supports it. As blockchain is constantly being reviewed by bitcoin users, hacks are unlikely.
