Overview of smart contract hacking Importance of understanding vulnerabilities Ethical considerations Disclaimer and challenge Prerequisites for hacking smart contracts Analyzing Smart Contracts
When it comes to smart contract hacking, one of the most important steps is analyzing the code. Viewing the code allows you to understand the inner workings of the contract and identify any potential vulnerabilities. It's crucial to only focus on contracts where the code is visible, as this allows for a more thorough analysis.
One tool that can be used to analyze contracts is the Ethereum Explorer. By inputting the contract's address, you can view the source code and identify any areas of concern. If the contract is verified, you can be more confident in its security. However, if the contract is not verified, it's best to move on to another one.
During the analysis, it's important to look for business logic flaws. These flaws can lead to vulnerabilities that can be exploited. By understanding the logic behind the contract, you can identify any potential flaws and determine the best approach for exploitation.
When choosing contracts for analysis, it's important to consider their relevance and potential impact. Look for contracts that handle significant amounts of value or have a large user base. Analyzing these high-value contracts can lead to more lucrative exploits.

Interacting with Smart Contracts
When it comes to smart contract hacking, understanding how to interact with smart contracts is essential. In this section, we will explore the different aspects of interacting with smart contracts and the tools that can be used.
Understanding function calls: reads and writes
Function calls in smart contracts can be categorized into two types: reads and writes. Readable functions allow you to retrieve data from the contract, while writable functions allow you to modify the contract's state.
By examining the functions available in a smart contract, you can identify which ones are readable and which ones are writable. This knowledge is crucial for understanding the potential vulnerabilities and attack vectors present in the contract.
Calling readable functions without authentication
One advantage of readable functions is that they can be called without authentication. This means that you can retrieve data from a smart contract without needing any special permissions or signing a transaction.
For example, you can call a readable function to retrieve the balance of a specific address in a token contract. This allows you to gather information about the contract and its users without interacting with the blockchain directly.
Creating a signer for authentication in Hardhat
In order to call writable functions, authentication is required. Hardhat, a powerful tool for smart contract hacking, allows you to create a signer for authentication purposes.
A signer is created by generating a wallet's private key. This private key is then used to authenticate smart contract calls, simulating the actions of an authorized user.
Calling readable and writable functions using Hardhat
With Hardhat, you can easily interact with smart contracts by creating script files and using the Hardhat API. By calling functions and passing the necessary parameters, you can perform actions such as transferring tokens, approving spending limits, and more.
Hardhat also allows you to simulate contract calls and test your attack hypotheses before executing them in a real-life scenario. This enables you to refine your strategies and identify potential vulnerabilities in the contract.
Overall, interacting with smart contracts requires an understanding of function calls, authentication, and the tools available for testing and experimentation. By mastering these concepts, you can enhance your smart contract hacking skills and identify potential exploits.
Testing Exploits Locally
When it comes to smart contract hacking, it is essential to test your exploits locally to ensure their effectiveness and minimize risks. In this section, we will discuss the steps involved in testing exploits locally and the tools that can be used.
Forking the blockchain for local testing
One of the first steps in testing exploits locally is forking the blockchain. Forking allows you to create a local copy of the Ethereum blockchain, which you can use for testing purposes. By having a local copy of the blockchain, you can simulate contract calls and test your exploits without incurring any gas fees or affecting the real network.
Configuring local testing environment in Hardhat
Hardhat, a popular development environment for Ethereum, allows you to configure your local testing environment easily. By using Hardhat's network configuration, you can specify the URL of a public RPC server or create your own local node. This ensures that you are interacting with the correct blockchain and enables accurate testing of exploits.
Simulating contract calls to test attack hypotheses
Once you have set up your local testing environment, you can start simulating contract calls to test your attack hypotheses. By interacting with the smart contracts using Hardhat's API, you can call functions, pass parameters, and observe the resulting state changes. This allows you to verify if your exploits work as expected before executing them in a real-life scenario.
Considering gas fees and transaction ordering
While testing exploits locally, it's important to consider gas fees and transaction ordering. Gas fees determine the cost of executing transactions on the Ethereum network, and they play a crucial role in the success of certain exploits. Additionally, transaction ordering can affect the outcome of your exploits, as other transactions may interfere with the desired state changes. Keeping these factors in mind during testing will help you create more robust and reliable exploits.
By testing exploits locally, you can gain confidence in their effectiveness and reduce potential risks. It allows you to refine your strategies, identify any vulnerabilities in the contract, and ensure that your exploits work as intended. Remember to always test exploits ethically and with the permission of the contract owner.
Exploit 1: Function Exposure
Understanding function exposure vulnerabilities:
Function exposure vulnerabilities occur when a public function can be called by unauthorized users. These vulnerabilities can allow attackers to manipulate the contract's state or access sensitive information. Identifying inconsistent function calls:
Inspect the contract's code to identify functions that should be private but are marked as public. Look for functions that can be called by any user, regardless of their role or permissions. Exploiting the 'approve' function:
In the example contract, the 'approve' function is marked as public, allowing anyone to change the approval for a specific address. By exploiting this vulnerability, an attacker can grant themselves permission to spend tokens from another user's account. This can result in unauthorized token transfers and potential financial losses for the victim. Fixes for function exposure vulnerabilities:
To fix function exposure vulnerabilities, developers should carefully review the permissions and access controls of each function. Ensure that sensitive functions are marked as private or internal, and can only be called by authorized users. Implement proper role-based access control to restrict function calls to the appropriate users. Exploit 2: Underflows and Overflows
Underflows and overflows are common vulnerabilities in smart contracts that can lead to serious consequences if not properly addressed. In this section, we will explore what underflows and overflows are, how to identify functions prone to these vulnerabilities, how to exploit the 'transfer' function, and the fixes for underflow and overflow vulnerabilities.
Explaining underflows and overflows
Underflows occur when a number goes below the minimum range, while overflows happen when a number exceeds the maximum range. In the context of smart contracts, underflows and overflows can occur when manipulating numbers, leading to unexpected behavior and potential vulnerabilities.
Identifying underflow/overflow-prone functions
To identify functions that are prone to underflows and overflows, carefully review the code and look for operations that involve arithmetic calculations or state updates. Pay close attention to functions that involve decrementing or incrementing values, as these are common areas where underflows and overflows can occur.
Exploiting the 'transfer' function
The 'transfer' function is a commonly used function in smart contracts that transfers funds from one address to another. However, if not properly implemented, it can be vulnerable to underflows and overflows. By exploiting the 'transfer' function, an attacker can manipulate the contract's state and potentially steal funds.
Fixes for underflow and overflow vulnerabilities
There are several ways to fix underflow and overflow vulnerabilities in smart contracts:
Use safe math libraries: Safe math libraries provide mathematical operations that prevent underflows and overflows by performing checks before executing calculations. Upgrade to the latest version of the Solidity compiler: Solidity versions 0.8 and above include built-in protection against underflows and overflows, automatically reverting transactions that exceed the maximum range. Perform extensive testing: Thoroughly test the smart contract to identify and address any potential underflow and overflow vulnerabilities. This includes simulating different scenarios and edge cases to ensure the contract behaves as expected. Follow best practices: Adhere to best practices when coding smart contracts, such as using data types with sufficient range, validating input parameters, and implementing proper error handling. By understanding underflows and overflows, identifying vulnerable functions, exploiting the 'transfer' function, and implementing fixes, you can enhance the security of your smart contracts and protect against potential vulnerabilities.
Exploit 3: Re-Entrancy Attacks
Understanding re-entrancy attacks:
Re-entrancy attacks occur when a contract is forced to call itself before the initial call finishes executing. This can lead to inconsistencies in the contract's state or, in the worst case, the unauthorized withdrawal of funds. Exploiting the 'withdraw' function:
In the example contract, the 'withdraw' function makes a delegate call to another contract. An attacker can create a contract that calls the 'withdraw' function repeatedly, creating a loop of calls. This loop prevents the contract from reaching the balance reset condition, allowing the attacker to continuously withdraw funds. Creating a contract for the attack:
To exploit the 'withdraw' function, an attacker needs to create a contract that includes a loop of function calls to the target contract. The loop should continue as long as the target contract has a positive balance to ensure continuous withdrawals. The attacker's contract should also include a function to receive the withdrawn funds. Fixes for re-entrancy vulnerabilities:
To fix re-entrancy vulnerabilities, developers should carefully review the logic of their contract functions and avoid making delegate calls to untrusted contracts. Implement checks and balances to prevent unauthorized withdrawals and ensure that state changes are properly handled. Consider using a lock mechanism that prevents multiple function calls from executing simultaneously. Exploit 4: Transaction Origin Manipulation
Transaction Origin Manipulation is another common exploit used in smart contract hacking. In this section, we will explore how this exploit works and how to protect against it.
Explaining transaction origin and message.sender
In Ethereum, every transaction has a transaction origin, which is the original sender of the transaction. The transaction origin can be different from the message.sender, which is the immediate caller of the function within the contract.
Exploiting the 'mint' function
One way to exploit the transaction origin is by manipulating the 'mint' function of a contract. The 'mint' function is responsible for creating new tokens and assigning them to a specific address. By manipulating the transaction origin, an attacker can mint new tokens for themselves without proper authorization.
Creating a contract to deceive the transaction origin
An attacker can create a contract that deceives the transaction origin. This can be done by using delegate calls or by manipulating the storage positions of variables within the contract. By deceiving the transaction origin, an attacker can bypass authentication and gain unauthorized access to the contract's functions.
Fixes for transaction origin vulnerabilities
To protect against transaction origin vulnerabilities, developers should:
Avoid relying solely on the transaction origin for authentication. Implement additional authorization mechanisms, such as role-based access control or signature verification. Use secure coding practices to prevent storage collisions and delegate call vulnerabilities. By implementing these fixes, developers can mitigate the risks associated with transaction origin vulnerabilities and protect their smart contracts from unauthorized access and exploitation.
Exploit 5: Storage Collision
Understanding storage collision vulnerabilities:
Storage collision vulnerabilities occur when variables in a contract share the same storage position. This can lead to unintended changes in contract state and potentially allow attackers to manipulate the contract's behavior. Identifying contracts with delegate calls:
Contracts that use delegate calls, such as the 'changeProxy' function in our example contract, may be vulnerable to storage collision attacks. Delegate calls allow for the execution of code from another contract, potentially affecting the storage positions of variables. Exploiting the 'changeProxy' function:
In our example contract, the 'changeProxy' function updates the storage position of the proxy contract. By exploiting this vulnerability, an attacker can change the storage positions of variables in the contract, potentially gaining unauthorized access or control. Switching variable positions to change contract behavior:
To exploit storage collision vulnerabilities, an attacker can deploy a contract that switches the positions of variables in the target contract. By changing the storage positions, the attacker can alter the behavior of the contract, potentially gaining control or manipulating its state. To protect against storage collision vulnerabilities, developers should:
Avoid using delegate calls unless absolutely necessary and thoroughly understand the potential implications. Ensure that variables have unique storage positions to prevent unintended changes in contract behavior. Perform extensive testing and auditing to identify and address any potential storage collision vulnerabilities. Hacking Challenge and Conclusion

The story of the Indexed Finance hack is one that has sent shockwaves throughout the cryptocurrency industry. With $16 million stolen and the price of an index fund crashing by 97%, users were left wondering how this could have happened. The hacker, who left behind a trail of clues, has raised questions about the security and trustworthiness of decentralized protocols.
Indexed Finance is a platform on Ethereum that offers index funds, allowing users to gain exposure to the entire cryptocurrency market. These index funds represent ownership in a diverse portfolio of tokens, making it easy for investors to diversify their holdings.
Before delving further into the details of the hack, it is important to understand the potential impact it can have on the cryptocurrency industry. The theft of such a large sum of money highlights the vulnerabilities and risks associated with decentralized finance. It also emphasizes the need for users to have a thorough understanding of the platforms they interact with.
The Hacker's Identity
As the story of the Indexed Finance hack unfolded, the team behind the platform discovered a trail of clues that led them to uncover the true identity of the hacker. It all started when a user named UmbralUpsilon reached out to the developers with questions about specific mechanisms used by the hacker. At the time, UmbralUpsilon claimed to be building an arbitrage bot and the developers willingly answered his questions, even sending him $2000 as an incentive to keep working on the project.
However, after the hack took place, UmbralUpsilon changed his username to BogHolder and deleted all his messages, which raised suspicions. The developers then made a shocking discovery - BogHolder was a warden at C4, a community code auditing platform. Evidence on the blockchain revealed that BogHolder had received prizes from C4 and had deposited and withdrawn funds from Tornado Cash, a privacy mixer.
Further investigation led the team to discover that tensors, a user who had joined the C4 Discord after the hack, was actually BogHolder. BogHolder had messaged another C4 organizer, asking for the Warden role back and requesting a change of address. This solidified the connection between BogHolder and the hack.
Indexed Finance also uncovered the hacker's digital footprint, including his GitHub accounts and online activity. They discovered that the hacker, whose real name is Andy, was an 18-year-old genius who had finished high school in 2016 and was currently a master's student at the University of Waterloo studying pure mathematics.
However, the team's investigation took a dark turn when they found evidence of Andy's extremist views and racist code comments. Despite his age, Indexed felt justified in doxing Andy and pursuing legal action against him.
Indexed filed a lawsuit against Andy, but it was discovered that another anonymous company called Cicada 137 had already sued him. Cicada represented the largest token holder who lost around $9 million in the hack. The search for Andy led to an arrest warrant being issued, but he had already fled the country. The case remains incomplete until Andy or his tokens are located.
While Andy's legal implications are uncertain due to the nature of decentralized protocols, his actions were undeniably unethical. The hack resulted in significant losses for those who held certain index funds, and the Indexed Finance platform has struggled to recover.
Despite his newfound wealth, Andy has expressed little concern about getting a job or living a normal life. His focus remains on his computer screen, seemingly content with the consequences of his actions.
Uncovering the Digital Footprint
As the investigation into the Indexed Finance hack unfolded, the team behind the platform took on the task of uncovering the hacker's digital footprint. Their efforts led them to several crucial discoveries that shed light on the true identity of the hacker.
Tracking the hacker's GitHub accounts
One of the first breakthroughs in the investigation was the identification of the hacker's GitHub accounts. The hacker, known as Andy, had registered for C4 using the GitHub account "mtheorylord1." This led the team to another GitHub account, "mtheorylord," which contained a single commit in a repository titled "Grade-12-Project." This commit provided evidence that the hacker had finished high school in 2016.
Discovering the high school connection
The team's investigation took them further into Andy's background, uncovering his connection to a high school in Ontario. They found an email address associated with Andy's high school project, which matched the email used to register for C4. They also found a StackExchange account with the same username, where Andy had asked a question about executing flash loans on Ethereum. This information solidified the connection between Andy and the hack.
Linking the hacker to extremist thinking
While delving into Andy's online presence, the team discovered evidence of his extremist views and racist code comments. This included the use of a racial slur in his code and ties to White supremacist ideologies. These findings raised serious ethical concerns for the team and provided further justification for their decision to dox Andy.
Ethical concerns and the decision to dox Andy
The decision to dox Andy, despite his age, was not made lightly. The team felt that his actions, which resulted in significant losses for users of Indexed Finance, warranted legal consequences. They believed that Andy, as an 18-year-old genius, was old enough to face the repercussions of his actions. Their investigation led them to file a lawsuit against Andy, but it was discovered that another anonymous company called Cicada 137 had already sued him. An arrest warrant was issued, but Andy had already fled the country, leaving the case incomplete until he or his tokens are located.
While the legal implications of Andy's actions within the context of decentralized protocols remain uncertain, the ethical concerns surrounding his behavior are undeniable.

The nature of the hack and Andy's defense:
Andy, the hacker behind the Indexed Finance hack, argues that his actions were not illegal but rather a complex series of transactions that exploited the operational logic of the smart contracts. He believes in the concept of "code is law" within the crypto community, where the code of the smart contracts dictates what is permissible. However, this viewpoint is controversial, and many argue that "law is law," meaning that traditional legal statutes, such as those against market manipulation and computer hacking, should still apply.
Market manipulation and computer hacking:
Andy's actions in manipulating prices and executing flash loans to drain funds from Indexed Finance can be seen as market manipulation. By artificially manipulating the price of the index fund, he tricked the smart contract into allowing him to buy the index funds at an extremely low price, resulting in significant financial losses for innocent investors. Additionally, his exploitation of vulnerabilities in the smart contracts can be considered a form of computer hacking.
The ethical implications of Andy's actions:
Regardless of the legal implications, Andy's actions in stealing $16 million from Indexed Finance have significant ethical concerns. His actions resulted in financial losses for users who were only seeking to diversify their risk through index funds. Furthermore, evidence of Andy's extremist views and racist code comments raise further ethical concerns. Despite his age, Indexed felt justified in doxing Andy and pursuing legal action against him.

How do Hackers Hide Themselves? - Staying Anonymous Online
In the world of cyberspace, anonymity is both a shield and a weapon. While online privacy is a fundamental right, some individuals misuse it for malicious purposes. This article explores how hackers hide themselves and stay anonymous online, shedding light on the techniques and tools they use.
Virtual Private Networks (VPNs):
VPNs are a common choice for hackers seeking anonymity. By routing their internet traffic through encrypted servers located in different countries, hackers can mask their true IP addresses. This makes it challenging to trace their online activities back to a specific location.
TOR (The Onion Router):
TOR is an anonymity network that directs internet traffic through a series of volunteer-run servers. It's a favorite among hackers because it conceals the source and destination of data, making it difficult to track. However, TOR isn't foolproof and has vulnerabilities.
Proxy Servers:
Proxy servers act as intermediaries between a user's device and the internet. By using proxy servers, hackers can hide their IP addresses and make it appear as if their requests are coming from a different source.
Encrypted Communication:
Hackers often use encrypted messaging platforms to communicate securely. End-to-end encryption ensures that only the intended recipient can decipher the messages, keeping their discussions private.
Spoofing Techniques:
Spoofing involves faking certain aspects of online communication. Hackers can spoof their IP addresses, MAC addresses, or DNS records to deceive security systems and investigators.
Disposable Email Addresses:
To avoid leaving a digital trail, hackers use disposable email addresses for registrations and communications. These temporary email accounts can be discarded after use.
Hacking Tools and Malware:
Some hackers deploy sophisticated hacking tools and malware to compromise other systems and hide their identities. These tools can obfuscate their digital fingerprints.
Public Wi-Fi and Public Computers:
Using public Wi-Fi networks and public computers can add a layer of anonymity. However, this method carries risks, as these networks are not always secure.
Cryptocurrencies:
Cryptocurrencies like Bitcoin offer a degree of financial anonymity. Hackers can receive payments for their services or ransomware attacks without revealing their real identities.
Secure Operating Systems:
Hackers sometimes use specialized, security-focused operating systems like Tails or Whonix to conduct their activities securely.
It's essential to note that while these techniques provide anonymity, they are not foolproof. Law enforcement agencies and cybersecurity experts are continually improving their methods for tracking and identifying cybercriminals. Additionally, many hackers are eventually apprehended due to mistakes or leaks in their operational security.
Ultimately, the use of anonymity tools and techniques can serve both ethical and unethical purposes. While some individuals use them for privacy and security, others exploit them for malicious intent. It's crucial to understand that online anonymity is a double-edged sword, and striking the right balance between privacy and security is essential.
As the digital landscape evolves, so do the methods employed by hackers to hide themselves. Staying informed about the latest cybersecurity trends and best practices is vital for individuals and organizations to protect themselves from cyber threats.
