Blockchain-Based Carding: Leveraging Decentralized Finance for Fraud

[CardingVenom]

In the ever-evolving world of carding, the emergence of decentralized finance (DeFi) and non-fungible tokens (NFTs) has opened up new avenues for fraudsters to launder stolen funds and avoid detection. Blockchain technology, once heralded for its potential to create transparent and secure financial systems, is now being exploited by carders to conduct sophisticated fraudulent activities. In this post, we will delve deep into how carders are leveraging DeFi platforms and NFTs to launder money and evade traditional detection methods.

The Rise of Decentralized Finance (DeFi)​

Decentralized Finance, or DeFi, refers to a financial system built on blockchain technology that operates without centralized intermediaries like banks or brokers. DeFi platforms offer a range of financial services, including lending, borrowing, trading, and earning interest on crypto assets. The decentralized nature of these platforms, combined with their pseudonymous features, makes them an attractive target for carders looking to launder stolen funds.

How Carders Exploit DeFi Platforms​

1. Liquidity Pools and Yield Farming: Carders can deposit stolen funds into liquidity pools on DeFi platforms, earning interest and fees in the process. By participating in yield farming, they can further increase their returns while obscuring the origin of the funds. For example, a carder might deposit stolen Bitcoin into a liquidity pool on a platform like Uniswap, earning fees from traders who swap tokens. They can then withdraw their funds, along with the earned interest, in a different cryptocurrency, making it harder to trace the original source.
2. Decentralized Exchanges (DEXs): Decentralized exchanges allow users to trade cryptocurrencies directly from their wallets, without the need for a centralized intermediary. Carders can use DEXs to swap stolen cryptocurrencies for more privacy-focused coins, such as Monero or Zcash, which offer enhanced anonymity features. For instance, a carder might swap stolen Bitcoin for Monero on a DEX like SushiSwap, making it extremely difficult for authorities to trace the transaction.
3. Flash Loans: Flash loans are a unique feature of DeFi platforms that allow users to borrow large amounts of cryptocurrency without providing collateral, as long as the loan is repaid within the same blockchain transaction. Carders can use flash loans to manipulate the price of tokens, conduct arbitrage, or even execute complex fraud schemes. For example, a carder might use a flash loan to temporarily inflate the price of a token, sell their stolen tokens at the inflated price, and then repay the loan, all within a single transaction.
4. Decentralized Lending and Borrowing: Carders can borrow stablecoins against their stolen cryptocurrency collateral on DeFi lending platforms. This allows them to access fiat-equivalent funds without directly converting their stolen crypto assets, adding an extra layer of obfuscation. For instance, a carder might deposit stolen Bitcoin as collateral on a platform like Aave to borrow DAI, a stablecoin pegged to the US dollar. They can then use the DAI for purchases or further laundering, while the original Bitcoin collateral remains locked in the smart contract.

Non-Fungible Tokens (NFTs) and Money Laundering​

Non-Fungible Tokens, or NFTs, are unique digital assets verified using blockchain technology. Unlike cryptocurrencies, which are fungible and interchangeable, NFTs represent ownership of a specific item, such as digital art, collectibles, or even real-world assets. The rise of NFTs has created new opportunities for carders to launder money through seemingly legitimate transactions.

How Carders Exploit NFTs​

1. Purchasing and Reselling NFTs: Carders can use stolen funds to purchase NFTs on platforms like OpenSea or Rarible. They can then resell these NFTs to other buyers, often at a loss, to create a paper trail of legitimate transactions. This technique, known as "NFT washing," can help obscure the origin of the stolen funds. For example, a carder might buy an NFT for 1 ETH and then sell it for 0.8 ETH, creating the appearance of a legitimate trade while laundering the remaining 0.2 ETH.
2. Creating and Selling Fake NFTs: Carders can create their own NFTs, often of low quality or copied content, and sell them on NFT marketplaces. By doing so, they can convert stolen cryptocurrencies into fiat or other cryptocurrencies through the sale of these NFTs. This method allows them to generate fake demand and inflate the value of their NFTs, making it easier to launder larger amounts of money.
3. Collaborative NFT Laundering: Carders are forming collaborative networks to create and sell NFTs collectively. These networks can include multiple wallets and accounts, making it harder for authorities to trace the flow of funds. For instance, a group of carders might create a series of NFTs and sell them through multiple accounts, distributing the proceeds among themselves to further obscure the money trail.
4. NFT Staking and Yield Farming: Some NFT platforms offer staking and yield farming opportunities, allowing users to earn additional tokens by locking their NFTs in smart contracts. Carders can use stolen funds to purchase NFTs and then stake them to earn yield, further complicating the trail of the original funds. For example, a carder might buy an NFT with stolen ETH and then stake it on a platform that offers additional tokens as a reward, creating a more complex and harder-to-trace financial history.

Case Study: A Successful NFT Money Laundering Operation (Example)​

To illustrate how NFTs are being used for money laundering, consider a recent operation that involved a group of carders collaborating to launder stolen cryptocurrency. The carders first pooled their stolen funds, primarily in Bitcoin and Ethereum, and used these funds to purchase a large number of low-quality NFTs from various creators. They then created multiple fake accounts and wallets to resell these NFTs on popular NFT marketplaces like OpenSea and Rarible.
The carders employed a strategy of "NFT washing," where they would buy and sell the same NFTs multiple times, creating a complex web of transactions that made it difficult to trace the origin of the funds. They also used flash loans to temporarily inflate the price of some NFTs, making them more attractive to potential buyers and increasing the likelihood of a successful sale.
Over a period of several months, the carders successfully laundered millions of dollars worth of stolen cryptocurrency through these NFT transactions. The use of multiple accounts and wallets, combined with the complex nature of NFT marketplaces, made it extremely challenging for authorities to detect and trace the fraudulent activity.

Additional Techniques and Strategies​

Beyond DeFi platforms and NFTs, carders are employing a range of additional techniques to exploit blockchain technology for fraudulent purposes:

1. Mixer Services: Carders use cryptocurrency mixers, also known as tumblers, to obscure the trail of their transactions. Mixers pool funds from multiple users and then redistribute them in random amounts to different addresses, making it difficult to trace the origin of the funds. For example, a carder might send their stolen Bitcoin to a mixer, which then redistributes the funds to multiple addresses, including the carder's new wallet, making it harder to link the funds to their criminal activity.
2. Privacy Coins: Carders are increasingly using privacy-focused cryptocurrencies, such as Monero and Zcash, which offer enhanced anonymity features. These coins use advanced cryptographic techniques to obscure transaction details, making it extremely difficult for authorities to trace the flow of funds. For instance, a carder might swap their stolen Bitcoin for Monero on a DEX, taking advantage of Monero's ring signature technology to hide the transaction details.
3. Cross-Chain Transactions: Carders are exploiting the interoperability of different blockchain networks to move funds across chains, further complicating the trail. For example, a carder might use a cross-chain bridge to move stolen Ethereum to the Binance Smart Chain, and then to another chain, making it harder for authorities to follow the money.
4. Smart Contract Exploits: Carders are targeting vulnerabilities in smart contracts on DeFi platforms to steal funds or manipulate transactions. By exploiting bugs or logical flaws in smart contracts, carders can siphon funds directly from liquidity pools or other DeFi protocols, often in a way that is difficult to detect and reverse.

The Future of Blockchain-Based Carding​

As blockchain technology continues to evolve, so too will the methods employed by carders to exploit it for fraudulent purposes. The increasing adoption of DeFi and NFTs, combined with the development of new blockchain networks and interoperability solutions, will provide carders with even more opportunities to launder money and evade detection.
For example, the rise of Layer 2 solutions and sidechains could offer carders new avenues for obscuring transaction trails, as these networks often have different privacy and security models compared to their underlying blockchains. Similarly, the development of decentralized identity solutions could be exploited by carders to create synthetic identities and further complicate the tracking of fraudulent activities.

Conclusion​

In conclusion, the emergence of DeFi and NFTs has created new and sophisticated avenues for carders to launder stolen funds and avoid detection. By exploiting the decentralized and pseudonymous nature of these platforms, carders can create complex transaction trails that are extremely difficult for authorities to trace. Techniques such as liquidity pooling, NFT washing, and the use of privacy coins are just a few examples of how carders are adapting to the evolving blockchain landscape.
