In this article, we will try to remember all the major theft of cryptocurrencies over the past 10 years.
1. Bitstamp $5.3 mln (BTC), January 4th, 2015
On January 4, 2015, the operational hot wallet of Bitstamp announced that it was hacked by an anonymous hacker and 19,000 Bitcoins (worth of $5 million) were lost.
The initiation of the attack fell on November 4, 2014. Then Damian Merlak, the CTO of the exchange, was offered free tickets to punk rock festival Punk Rock Holiday 2015 via Skype, knowing that Merlak is interested in such music and he plays in the band. To receive the tickets, he was asked to fill out a participant questionnaire by sending a file named “Punk Rock Holiday 2015 TICKET Form1.doc”. This file contained the VBA script. By opening the file, he downloaded the malware on his computer. Although Merlak did not suspect wrong and has opened the "application form", to any critical consequences, this did not open access to the funds of exchange.
The attackers, however, did not give up. The attack continued for five weeks, during which hackers presented themselves as journalists, then headhunters.
Finally, the attackers were lucky. On December 11, 2014, the infected word document was opened on his machine by Bitstamp system administrator Luka Kodric, who had access to the exchange wallet. The file came to the victim by email, allegedly on behalf of an employee of the Association for computer science, although in fact, as the investigation showed, the traces of the file lead deep into Tor. Hackers were not limited to just one letter. Skype attacker pretending to be an employee of the Association for computing machinery, convinced that his Frame though to make international honor society, which required some paperwork. Kodric believed.
By installing a Trojan on Kodri?'s computer hackers were able to obtain direct access to the hot wallet of the exchange. The logs show that the attacker, under the account of Kodric, gained access to the server LNXSRVBTC, where he kept the wallet file.dat, and the DORNATA server where the password was stored. Then the servers were redirected to a certain IP address that belongs to one of the providers of Germany.
There are still no official reports of arrests in this case. Obviously, the case is complicated by the fact that the hackers are outside the UK, and the investigation has to cooperate with law enforcement agencies in other countries.
2. GateHub $9.5 mln (XRP), June 1th, 2019
Hackers have compromised nearly 100 XRP Ledger wallets on cryptocurrency wallet service GateHub. The incident was reported by GateHub in a preliminary statement on June 6.
XRP enthusiast Thomas Silkjær, who first noticed the suspicious activity, estimates that the hackers have stolen nearly $10 million worth of cryptocurrency (23,200,000 XRP), $5.5 million (13,100,000 XRP) of which has already been laundered through exchanges and mixer services.
GateHub notes that it is still conducting an investigation and therefore cannot publish any official findings. Also, GateHub advises victims to make complaints to the relevant authorities of their jurisdiction.
3. Tether, $30.9 mln (USDT), November 19th, 2017
Tether created a digital currency called "US tokens" (USDT) — they could be used to trade real goods using Bitcoin, Litecoin and Ether. By depositing $1 in Tether, the user received 1 USD, which can be converted back into fiat. On November 19, 2017, the attacker gained access to the main Tether wallet and withdrew $ 30.9 million in tokens. For the transaction, he used a Bitcoin address, which means that it was irreversible.
To fix the situation, Tether took action by which the hacker was unable to withdraw the stolen money to fiat or Bitcoin, but the panic led to a decrease in the value of Bitcoin.
4. Ethereum, $31 mln (ETH), July 20th, 2017
On July 20, 2017, the hacker transferred 153,037 Ethers to $31 million from three very large wallets owned by SwarmCity, Edgeless Casino and Eternity. Unknown fraudster managed to change the ownership of wallets, taking advantage of the vulnerability with multiple signatures.
First, the theft was noticed by the developers of SwarmCity.
Further events deserve a place in history: "white hackers" returned the stolen funds, and then protected other compromised accounts. They acted in the same way as criminals, who stole funds from vulnerable wallets — just not for themselves. And it all happened in less than a day.
5. Dao (Decentralized Autonomous Organization) $70 mln (ETH), June 18th, 2016
On June 18, 2016, members of the Ethereum community noticed that funds were being drained from the DAO and the overall ETH balance of the smart contract was going down. A total of 3.6 million Ether (worth around $70 million at the time) was drained by the hacker in the first few hours. The attack was possible because of an exploit found in the splitting function. The attacker/s withdrew Ether from the DAO smart contract multiple times using the same DAO Tokens. This was possible due to what is known as a recursive call exploit.
In this exploit, the attacker was able to "ask" the smart contract (DAO) to give the Ether back multiple times before the smart contract could update its own balance. There were two main faults that made this possible: the fact that when the DAO smart contract was created the coders did not take into account the possibility of a recursive call, and the fact that the smart contract first sent the ETH funds and then updated the internal token balance.
It's important to understand that this bug did not come from Ethereum itself, but from this one application that was built on Ethereum. The code written for the DAO had multiple bugs, and the recursive call exploit was one of them. Another way to look at this situation is to compare Ethereum to the Internet and any application based on Ethereum to a website: if a website is not working, it doesn't mean that the Internet is not working, it simply means that one website has a problem.
The hacker stopped draining the DAO for unknown reasons, even though they could have continued to do so.
The Ethereum community and team quickly took control of the situation and presented multiple proposals to deal with the exploit. In order to prevent the hacker from cashing in the Ether from his child DAO after the standard 28 days, a soft-fork was voted on and came very close to being introduced. A few hours before it was set to be released, a few members of the community found a bug with the implementation that opened a denial-of-service attack vector. This soft fork was designed to blacklist all the transactions made from the DAO.
6. NiceHash, 4736.42 (BTC), December 6th, 2017
NiceHash is a Slovenian cryptocurrency hash power broker with integrated marketplace that connects sellers of hashing power (miners) with buyers of hashing power using the sharing economy approach.
On December 6, 2017, the company's servers became the target of attack. At first, Reddit users reported that they could not access their funds and make transactions — when they tried to log in, they were shown a message about a service interruption. In the end, it became known that the service had undergone a major cyberattack and 4736,42 Bitcoins disappeared without a trace.
Despite heavy losses, NiceHash was able to continue working, but CEO and founder Marco Koval resigned, giving way to a new team. The company managed to maintain the trust of investors and began to strengthen the protection of its systems.
7. Mt.Gox, 850000 (BTC), June 19th, 2011
The Hacking Of Mt.Gox was one of the biggest Bitcoin thefts in history. It was the work of highly professional hackers using complex vulnerabilities.
A hacker (or a group of hackers) allegedly gained access to a computer owned by one of the auditors and used a security vulnerability to access Mt.Gox servers, then changed the nominal value of Bitcoin to 1 cent per coin.
Then they brought out about 2000 BTC. Some customers, without knowing it, conducted transactions at this low price, a total of 650 BTC, and despite the fact that the hacking hit the headlines around the world, no Bitcoin could be returned.
To increase investor confidence, the company has compensated all of the stolen coins, placed most of the remaining funds in offline storage, and the next couple of years was considered the most reliable Bitcoin exchanger in the world.
However, it was only an illusion of reliability.
The problems of the organization were much more serious, and the management probably did not even know about them.
CEO of Mt.Gox, Mark Karpeles, was originally a developer, but over time he stopped delving into technical details, basking in the rays of glory — because he created the world's largest platform for cryptocurrency exchange. At that time Mt.Gox handled over 70% of all Bitcoin transactions.
And, of course, there were those who wanted to take advantage of the technological weakness of the service. At some point, hackers made it so that Bitcoins could be bought at any price, and within minutes millions of dollars worth of coins were sold — mostly for pennies. World prices for Bitcoin stabilized in a few minutes, but it was too late.
As a result, Mt.Gox lost about 850,000 Bitcoins. The exchange had to declare bankruptcy, hundreds of thousands of people lost money, and the Japanese authorities arrested CEO Mark Karpeles for fraud. He pleaded not guilty and was subsequ...
Do you consider Ethereum’s transition to proof of stake (PoS-PoW) in January to be as big as an event in terms of impact on supply as Bitcoin’s halving? Though we won’t have the exact numbers, should we expect at least an 80% reduction in annual issuance of Ether? I suppose we’d also have to compare the inflation rate of the two as well.

In our new Daily Rundown series, we aim to give you an inside look into a day at the Crypto Blockchain Plug office through the eyes of those who know it best — our team members. This week, we highlight Gina Marie, Executive Assistant in Inglewood, CA. By taking a walk in Gina's shoes, we hope to give you a peek into the exciting and fast-paced schedule of the Crypto Blockchain Plug team.
10:00 am hop on the first of 4 freeways to travel 77 miles in Inglewood crossing my fingers that there are no accidents or delays. I keep a flash drive with my favorite playlists that are sure to keep me in the best of spirits in case I do run into any obstacles.
11:45 am Open up my Nexkey app on my phone to allow me open the door without a key. Scan the lounge and office areas as I make my way to my desk, to be sure that they are always “Tour Ready”. I stay ready to give a tour to the large number of people who visit our lounge for a tour.
12:00 pm I greet my Boss, who has been here since 9am, not to mention she left here last night at midnight and by the way is that even 8 hours of sleep? I power up my workstation the grab my pen and pad for our briefing session. Hoping that no one brought donuts today! I am such a sucker for donuts. The phone rings continuously while I am trying to remotely open the front door for a customer going to the BTM downstairs.
12:30 pm Open my 7 calendars and prioritize the events for the day, first by checking the multiple avenues that we have in place for our clients and their friends to RSVP for our events. then I post new daily events on Eventbrite, Meetup, LA Patch, Black N LA, Alignable and LinkedIN for the next week. Once I am able to see how many RSVP’s we have for the day’s event(s), I know how many people to prepare for. I make a sign in sheet for tonight's event and enter the data from the guest from the event last night. It is Monday so I can not forget to send out the weekly Constant Contact "This Week at the PLUG" to our mailing list of 2,070. While I am posting the gentleman at the BTM needs assistance and down the stairs I go to assist him. Thank God I didn't wear those cute heels today because this is my second trip down to assist him. But customer service is what I DO!!
1:00 pm Open emails of course by order of most important, however it seems that each one is very important these days. Track our email (opened and clicked) reports to see how many people are actually engaging in our email marketing campaign. Manage current contacts and add new contacts. Another client at the door needing to be clicked in but this time it is a lady who flew in from Atlanta to LAX. She explains that she is a flight attendant for a company that starts with South and ends with West that lives in Atlanta however she wants a Membership here so when she is on layovers she can learn Crypto. Yeahhh, she bought at Plug Pass Membership and Najah thanked her for her support. Then I go back to making flyers for next weeks events.
2:00 pm Check our company website to see if there are any new subscriptions, if so get them welcomed in and respond to any questions that have been submitted. No question is a stupid question. In our Coin Lounge I go hang another set of Crypto Currencies because we just got some new frames. Perfection our Coin Lounge is beautiful.
2:30 pm Give personal tours, sign up new members, renew current members, I think I fall in love with this place a little more each time I give a tour.
3:00 pm Check our social media pages to see that our scheduled content has gone out and see the responses. Today I will meet with our social media experts to provide them with the new content for upcoming posts and discuss new strategies.
4:00 pm I’m starving and as usual I cannot decide whether I want a veggie burger from “The Habit” or a vegan burrito from “Stuff I Eat” a local Inglewood business. Shameless Plug!
4:30 pm “Financials at 4:30” Reconcile the company expense tracker, log expenses and incoming funds, balance Petty Cash
5:30 pm Inventory our “Bitcoin Buys R Us” store. Prepare to reorder, these items go quickly! My personal favorite is the baby blue “I accept Bitcoin” t-shirt. But I am also excited about our newest addition which is a micro sized mining rig that fits in the palm of your hand.
6:00 pm Now is the time for me to work on those spreadsheets and operations documents. I save this for the end of the day because I need to be able to focus on the details with minimal interruptions.
6:30 pm Yikes its already almost 7:00 pm and people are going to be pouring in for our evening event, I must get the food and beverages ready and set the atmosphere for an amazing event!
7:00 pm Assist our guest speakers with their accommodation needs and greet our special guests. I must remember to take pictures to share.
8:00 pm I’m back in the car ready to take my 1 ½ hour journey home and hit my 4 freeways only this time no playlist, I enjoy reflecting on my day and how much I enjoy my job. For real no Brownie Points Needed.
