The technical vulnerabilities associated with blockchain are not as widely recognized. Blockchain is often touted as being secure, immutable and "unhackable". There are, however, many vulnerabilities associated with cryptocurrencies and their ecosystems, some human and some technical.

This should not be surprising. We can learn a lot from history. As Jesse James showed in the wild west, Charles Ponzi showed us in , and as hackers show us day in and day out, no matter how secure a financial institution, financial application, or financial asset is, someone will try to find a way to steal it, defraud or trick people out of it, or hack it.

Sadly, the same is true with digital currencies. Some hacks are by lone hackers, but many are by sophisticated cybercrime organizations. According to a recent article In the MIT Security review, the hype that these assets are unhackable are "dead wrong". According to the article: In short, while blockchain technology has been long touted for its security, under certain conditions it can be quite vulnerable. Sometimes shoddy execution can be blamed, or unintentional software bugs. Other times it's more of a gray area-the complicated result of interactions between the code, the economics of the blockchain, and human greed.

That's been known in theory since the technology's beginning. Now that so many blockchains are out in the world, we are learning what it actually means-often the hard way. Blockchain technologies are not invulnerable and have actually many known vulnerabilities, just as with any software.. In other words, forget what you heard from Bitcoin boosters - just because information or currency is on a blockchain doesn't necessarily mean that it's more secure than any other form of storage.

In fact, the same qualities that make blockchain technology so secure may also be the source of several unique vulnerabilities - a stark reminder that despite the hype, cryptocurrencies can't entirely sidestep the vulnerabilities of any other banking systems.

One vector is fraud associated with online marketplaces. Clients entrusted their assets to Quadriga, which provided false assurances that those assets would be safeguarded. In reality, Cotten spent, traded and used those assets at will. He opened Quadriga accounts under aliases and credited himself with fictitious currency and crypto asset balances which he traded with unsuspecting Quadriga clients.

He sustained losses when the price of crypto assets changed causing a shortfall in assets to satisfy client withdrawals. He covered this shortfall with other clients' deposits, in effect, operating a Ponzi scheme. He also misappropriated millions in client assets to fund his lifestyle.

For example, in the U. A substantial part of the bitcoin transferred or their traceable proceeds ended up at accounts held by the the Binance and Kraken exchanges. Private key security attacks are also a known means of allowing malicious actors to steal cryptocurrencies. A private key allows individuals to access funds and verify transactions. An attacker who has discovered a vulnerability in an elliptic curve digital signature algorithm, for example, can recover a user's private key.

If a private key is stolen, it is difficult to track any related criminal activity and recover the relevant blockchain asset. A recent one involved the cryptocurrency exchange Cryptopia, a New Zealand exchange that operated globally. In January Cryptopia's servers were hacked and private keys held by the exchange were used to transfer cryptocurrencies to an undisclosed external exchange.

Cryptopia temporarily suspended its operations and eventually was put into liquidation. The case resulted in a lengthy decision by a New Zealand Court in Ruscoe v Cryptopia Limited in liquidation [] NZHC 8 April , which had to decide how the remaining assets of the exchange should be distributed as between account holders and unsecured creditors. The court decided that cryptocurrencies were property and that Cryptopia was a trustee of separate trusts, one for each cryptocurrency with the beneficiaries being all account holders holding currency of the relevant type.

Another example of a private key security attack was described in the U. It involved fraudulent trading using a person's trading account with the cryptocurrency exchange Binance. It was perpetrated by unauthorized access to the plaintiff's private key.

Hackers have also been known to steal the keys to cryptocurrency wallets. One of the best known examples is Mt Gox, one of the first bitcoin exchanges which was based in Tokyo. During its heydays in the early s, Mt. In hackers used stolen credentials to transfer bitcoins. Deficiencies in network protocols also resulted in several thousand bitcoins being "lost".

This scam attempts to obtain a user's credentials without their knowledge through various tricks such as email. For example, fraudsters send wallet key owners emails posing as a legitimate source asking users for their credentials using fake hyperlinks. Reportedly , the police, who were assisted by the FBI and U. In another case, BlockFi which offers crypto services for individuals and institutional clients was subject to a SIM swap attack.

In this case, only personal information and no funds were accessed. An example of this is the Poly network hack which occurred In August The hack targeted the Poly Network, a cross-blockchain interoperable bridge that enables users to transfer crypto-assets from one blockchain to another. Transfers are accomplished by locking tokens on a source blockchain and unlocking them on a destination one. After a transaction has occurred on a source blockchain, the Poly Network Keepers sign blocks of the source blockchain that contain the original transaction.

The keeper then submits the signed block to a smart contract manager on the destination blockchain. The smart contract manager assesses the signatures' validity, and if it is valid then the contract executes the transaction on the destination blockchain. The hacker exploited a vulnerability in the EthCrossChainManager smart contract manager. The hacker did this by changing and compromising trusted entities called "keepers" stored in the EthCrossChainData contract that facilitate the cross chain transactions to unlock tokens on the destination blockchain without locking the tokens on the source blockchain, essentially managing to duplicate tokens across two blockchain networks.

By taking control of the keepers the attacker was able to trick EthCrossChainManager contract into executing cross-chain transactions that weren't real on the source blockchain. People with tokens on the source blockchain suffered losses. The hacker later returned funds to the Poly Network. The DAO was a Decentralized Autonomous Organization, a term that describes a "virtual" organization embodied in computer code and executed on a distributed ledger or blockchain.

The DAO was created by Slock. Luckily, before the hacker could move the ETH from that address Slock. Blockchains rely on real-time, large data transfers. Hackers can intercept real-time large data transfers such as by hijacking IP prefixes or dropping connections momentarily, preventing the system from reaching consensus. Blockchain participants aren't aware of the threat, but behind the scenes, fraudsters may have extracted confidential data or currencies. Using a so called BGP Hijacking Attack, a hacker can manipulate BGP and intercept the blockchain network to route traffic to destinations determined by the hacker.

They usually work with a public and private key pair for signature and are as secure as the underlying cryptosystem they use. The public-key algorithm used for these keys have known attacks that can be applied. Blockchains commonly use proof of work as their protocol for verifying transactions. This process, also known as mining, involves nodes spending vast amounts of computing power to prove themselves trustworthy enough to add information about new transactions to the database.

If a miner or pool of miners are able to gain control of a majority of the network's mining power they can arbitrarily manipulate and change blockchain information such as by reversing a transaction and initiating a double-spending attack by creating an alternative version of the blockchain a fork. These attackers can make the fork the authoritative version of the chain and proceed to spend the same cryptocurrency again double spending. In another case, the mining pool "ghash. The fact that a single mining pool represented such a high proportion was a serious concern, and many miners dropped out of the pool.

Technology and Cyber Security Incident Reporting Advisory August The Advisory is intended to support a coordinated and integrated approach to OSFI's awareness of, and response to, technology and cyber security incidents. It has very broad criteria for reporting incidents including cyberattacks, third party breaches, extortion threats, and impacts to financial market settlements.

It deals with, among other things, cyber security and technology operations. Cyber Security: "Outcome: A secure technology posture that maintains the confidentiality, integrity and availability of the FRFI's technology assets. The environment is kept current and supported by robust and sustainable technology operating processes.

Civil remedies Obtaining remedies for Internet based wrongs are a continuing exercise of wac a mol. Obtaining effective civil remedies against blockchain hackers is, without doubt, challenging. They act at the speed of the internet, anonymously, almost always reside and act from foreign jurisdictions, and are notorious for covering their tracks including by peeling their stolen crypto assets to obfuscate recoveries.

While it is possible to investigate and trace transfers of cryptocurrencies from public blockchains, recovering those assets or tracing those assets once converted into fiat currency can be difficult. There are however several cases that show that if the attacked party acts quickly there are legal remedies that can be used to try to recover stolen or transferred crypto assets.

Case study An example is the U. In this case a Canadian insurance company the Insured Customer was subject to a ransomware attack that encrypted and locked up its computer systems. It had cyber insurance from an English insurer the "Insurer". Note, I could have chosen fact a fact pattern from other reported cases because the problems in obtaining remedies are very similar, only the alleged criminal behavior is different.

In the U. The rest of the funds were converted into a fiat currency. The relief claimed and the court's order are described below. An order that the hearing be conducted in private and for an anonymity order The Insured asked for an order that the hearing be conducted in private and for an anonymity order.

This order was granted. The publicity would have defeated the object of the hearing. The overarching purpose of the application was to assist the applicant in its efforts to recover the If the hearing was held in public there is a strong likelihood that the object of the application would be defeated because it would potentially tip off the persons unknown to enable them to dissipate the bitcoins.

However, the reason you can use it as a legal tender is that the Government that issued that note usually through their Central Bank guarantees to back the monetary value of that note. However, not everyone is happy with the current state of the financial industry. Why do we need centralized entities e.

There are a couple of benefits of a decentralized model including privacy of transactions and money property , inability of law enforcement to seize funds, possibly reduced transaction fees, and widespread access even to the unbanked who are estimated at 2 billion people globally. We generally trust the central entities handling our money and when we pay someone, that person also trusts that their own central entity will honor the payment.

Enter the world of Cryptocurrency. Simply put, a cryptocurrency is a digital currency that relies on cryptography for the creation of the currency units and also uses cryptography to verify the transfer of units between parties. Control is decentralized and everyone on the network has access to each other, without a central entity controlling the system.

So how is trust maintained in a network like this? This record is kept in a publicly accessible ledger history of records called a Blockchain. This process of mining is computationally intensive and on the average, new blocks a group of transaction records are created every 10 minutes on the bitcoin blockchain.

Note: One of the incentives of mining is the ability to earn cryptocurrency units. However, since so many other people are also trying to compute acceptable blocks to be added to the blockchain, it is more of a race against time. As such, people form Mining Pools to put their resources together and rewards are shared among the pool members. Since blocks are chained together with a cryptographic function, it is extremely difficult for someone to go back and change something e.

The computational difficulty in forging fake blocks is what makes the Blockchain secure in terms of integrity and trust of information stored in it. Cryptocurrency from a Networking Perspective Based on the brief description of cryptocurrencies that we did above, some questions should come to your mind from a networking perspective.

For example, how does one party transfer units of the currency to another party? Over which medium does this transfer happen? Also, over which medium do all the nodes on a network have access to the blockchain? If one of the goals of cryptocurrencies like Bitcoin is widespread access, then they need to rely on an infrastructure that everyone already has access to — the Internet.

Note: Even though all bitcoin nodes are equal no hierarchy , nodes can perform different functions. As such, there are different types of bitcoin nodes like full nodes, mining nodes, SPV nodes, and so on. You can read more about that here.

Whoever wishes to know more about Bitcoin and Cryptocurrencies, should definitely start from the Andreas Antonopoulos YouTube page. General Security Attacks on Cryptocurrencies As with any technology, especially one that is exposed on the Internet, cryptocurrencies are subject to various security threats and attacks including: Man-in-the-Middle MITM and Hijacking attacks: In a MITM attack, an attacker gets in the middle of the communication between a victim and the rest of the network or a particular subset of the network.

The attacker can intercept messages meant for the victim or from the victim, and result in cryptocurrency issues like transaction delay, loss of mining revenue, and wastage of computing resources. This happened in These attacks are usually done against digital currency exchanges, effectively locking out legitimate users from accessing their virtual money. All these attacks happened in , so they are common enough.

Theft: Even though the underlying blockchain technology itself may be secure against theft to a large extent , the implementation and services that use this technology may not be. There have been several instances where bitcoin and other cryptocurrencies have been stolen from one party or several parties to another, usually untraceable, party.

Mining attacks: Like we already said in this article, mining requires a lot of computational resources. Attackers have therefore found a way to use the computers or servers of unsuspecting victims to mine cryptocurrency. There is a scary report here about such attacks. This could be a sign that your computer is being used to mine cryptocurrency. Keep in mind that some websites are upfront about it.

Instead of showing you ads for their free service, they ask you to help them mine cryptocurrency instead. But what happens if an attacker is able to modify a DNS entry so that users are directed to a different destination than intended? By attacking DNS, users of the MEW service were redirected to a different and similar looking website and once they entered their login details, some of their cryptocurrency units were stolen.

Focus: Routing Attacks on Cryptocurrencies Having covered some of the attacks on cryptocurrencies, let us now focus on some of the ways the underlying network infrastructure can be attacked, affecting cryptocurrencies.
