Various technical details, including code about Binance's security procedures, were included in the leaked material. Interestingly, this contained details on multi-factor authentication (MFA) and passwords. A large portion of the code that was made public concerned systems that were identified as "prod," denoting a link to Binance's operational website as opposed to test or development environments.
On January 5, 2024, 404 Media contacted Binance to inform the exchange about the compromised data, which is when the problem became apparent. Binance then retaliated by sending GitHub a copyright removal request. Binance admitted in this request that internal code from the disclosed material "poses a significant risk" to the exchange, resulting in "severe financial harm" as well as possible user misunderstanding or harm.
Even after admitting the leak, Binance sent out a representative to try and reassure its user base. According to the spokesman, Binance's security team examined the circumstances and came to the conclusion that the code that had been leaked was not similar to the code that was being produced at the time. The representative emphasized the protection of users' data and assets and stated that there was only a "negligible risk" from the compromised information.
The significance of strong security procedures in the Bitcoin sector is highlighted by this occurrence. Crypto exchanges are required to uphold strict security procedures because of their role in managing users' sensitive information and financial assets. The prolonged public disclosure of security-related code and internal passwords on a public forum calls into doubt the effectiveness of Binance's security protocols.
Another level of worry is raised by the exposed data, especially the code about security protocols like multi-factor authentication and passwords. These kinds of security lapses can have serious repercussions, including the compromise of user funds and accounts. It draws attention to the continuous difficulties Bitcoin platforms have in maintaining the integrity and confidentiality of their internal systems.
Hacking organizations 'Lazarus' and 'APT38' supported by the North Korean government were responsible for the loss of $100 million worth of Ethereum from Harmony Horizon in June 2022.
The funds and the seizure of stolen assets were reported to the authorities. The exploiters' activities closely resembled the attempt, which was undertaken on January 13, 2023, since more than $60 million was attempted to be laundered.
The Binance chain, Bitcoin, and Ethereum transfers are made possible through Harmony's Horizon Bridge. Numerous tokens worth $100,000,000 were taken from the network on June 23, 2022.
North Korean cybercriminals were actively shifting a portion of Harmony's Horizon bridge funds during the last weekend as the price of bitcoin approached $24,000. While several cryptocurrency exchanges instantly froze certain cash, Binance CEO Changpeng Zhao (CZ) claimed that some exchanges are not helpful in fighting crime, which made it easier to convert ETH to BTC.
According to reports, the APT38 was able to convert some of the $27 million in Ethers to Bitcoin and withdraw the money from exchanges. The Lazurus group has reportedly been shifting laundered money to a number of addresses in order to mask their true identity through multiple layers.
With the use of its Horizon Bridge, Harmony can transmit data to and from the Ethereum network, Binance Chain, and Bitcoin. On June 23, a number of tokens from the network valued at roughly $100 million were taken.
After the exploit, the Tornado Cash mixer processed 85,700 Ether, which was then deposited at various addresses. The hackers began transferring about $60 million of the stolen money via the Ethereum-based anonymity protocol RAILGUN on January 13. 350 addresses have been linked to the attack through numerous exchanges in an effort to escape detection, according to research by the cryptocurrency tracking tool MistTrack.
Cryptocurrency exchanges like Binance and Huobi have alerted authorities about stolen Harmony's Horizon Bridge funds by freezing them. This demonstrates how DeFi platforms and centralized exchanges are dependent on one another.
According to internet sleuth ZachXBT, the funds were stolen from the Harmony blockchain bridge hack from last year, which led to a whopping $100 million crypto compromise. Apparently, the same hacker group utilized Tornado Cash, a now banned crypto mixer that conceals names of people involved in the transaction, in order to carry out the attack.
As per the analysis, conducted by token movements, the ETH was routed through the anonymity system Railgun before being collected in wallets and sent to three significant crypto exchanges, possibly to be exchanged for fiat currency.
ZachXBT shared details of this week’s token movements on Twitter, claiming Lazarus Group has had “a very busy weekend” moving funds.
In the follow-tweets, ZachXBT also linked to the website Chainabuse.com where he shared a list of approximately 350,000 unique wallet addresses that were involved in the Friday’s operation.
On Monday, Binanace CEO Changpeng Zhao, better known as CZ too, commented on the situation. CZ claims that the hackers used Huobi, a competing exchange, rather than Binance this time as one of their exchanges. The hacker's accounts were subsequently frozen with Binance's assistance, he says.
CZ also disclosed that 124 BTC ($2.6m) had been seized from the hackers, indicating at least some of their ETH has been converted to BTC.
“We detected Harmony One hacker fund movement. They previously tried to launder through Binance and we froze his accounts. This time he used Huobi. We assisted Huobi team to freeze his accounts. Together, 124 BTC have been recovered,” he wrote.
Although, Huobi did not comment on the matter other than retweeting an article claiming that the exchange had frozen accounts containing money connected to the hack.
According to a report from South Korea's National Intelligence Service from December of last year, North Korean hackers have stolen more than $1 billion in digital assets since 2017.
Moreover, the report claims that around $626 million, or more than half of that estimated tally, was taken in 2022. It also stated that it is suspected that the North Korean government uses the money obtained from the theft to advance Pyongyang’s nuclear weapons program.
The investigations for bankruptcy commenced last week when FTX experienced an $8 billion shortfall due to a run-on deposit. Consequently, this led to the company which was once regarded as one of the safest and most reliable institutions of the freewheeling crypto industry crumbling overnight.
The exchange’s founder Sam Bankman-Fried reportedly transferred $10 billion of customer funds from FTX to his trading company ‘Alameda Research.’ A large amount of that total fund has since disappeared. The total amount is said to be between $1-2 billion.
The financial hole later came to light in records shared by Bankman-Fried with other senior executives last Sunday. The records provided a real-time account of the situation, some sources said.
The company’s sudden downfall due to the run-on deposits last week left FTX unable to fulfill its customers' demands. Consequently, Bankman-Fried struck a rescue deal to sell his firm to its largest rival exchange, Binance.
After a lengthy online skirmish between Bankman-Fried and Changpeng Zhao, CEO of Binance, a review stating FTX’s finances revealed various problems, posing as a deal breaker and Binance pulled out of the deal. Bankman-Fried attempted to secure new financing but was unable to, and later declared bankruptcy. The Justice Department and SEC are currently looking into his management of FTX. They are apparently focusing on whether FTX inappropriately transferred customer funds to Alameda Research.
In regards to the case, Associate Professor in Finance Technology at the University of Liverpool, Gavin Brown referred to a recent report that suggested “42% of the exchanges which failed simply disappeared without traces.”
According to Prof Brown “In the event of exchange failure, or even bankruptcy, it is the investors who are on the hook for losses” He, along with other industry experts warned that often smaller investors often end up back of the queue, after the remains of a crypto business are divided among themselves. They doubt much money will be coming back.
"The unfortunate news is that the money's all gone. It's just not there anymore. Investors should expect pennies on the dollar," says crypto blogger and author David Gerard.
