Data Theft Repackaged: A Case Study in Malicious Wrapper Packages on npm
The Socket Research Team breaks down a malicious wrapper package that uses obfuscation to harvest credentials and exfiltrate sensitive data.
@ethersproject/providers
Advanced tools
@ethersproject/providers is a module from the ethers.js library that provides a way to interact with Ethereum nodes. It allows developers to connect to Ethereum networks, query blockchain data, and send transactions.
Connecting to a Provider
This feature allows you to connect to an Ethereum node using a JSON-RPC provider. In this example, we use Infura as the provider.
const { ethers } = require('ethers');
const provider = new ethers.providers.JsonRpcProvider('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
Querying Blockchain Data
This feature allows you to query blockchain data. In this example, we fetch the current block number from the Ethereum network.
const { ethers } = require('ethers');
const provider = new ethers.providers.JsonRpcProvider('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
async function getBlockNumber() {
const blockNumber = await provider.getBlockNumber();
console.log('Current block number:', blockNumber);
}
getBlockNumber();
Sending Transactions
This feature allows you to send transactions on the Ethereum network. In this example, we create a wallet instance and send a transaction to a recipient address.
const { ethers } = require('ethers');
const provider = new ethers.providers.JsonRpcProvider('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
const wallet = new ethers.Wallet('YOUR_PRIVATE_KEY', provider);
async function sendTransaction() {
const tx = {
to: '0xRecipientAddress',
value: ethers.utils.parseEther('0.01')
};
const transaction = await wallet.sendTransaction(tx);
console.log('Transaction hash:', transaction.hash);
}
sendTransaction();
web3.js is a popular library for interacting with the Ethereum blockchain. It provides similar functionalities to @ethersproject/providers, such as connecting to Ethereum nodes, querying blockchain data, and sending transactions. However, web3.js has a larger community and more extensive documentation.
ethjs is a lightweight JavaScript library for interacting with the Ethereum blockchain. It provides basic functionalities similar to @ethersproject/providers, such as sending transactions and querying blockchain data. However, it is less feature-rich and has a smaller community compared to ethers.js.
This sub-module is part of the ethers project.
It contains common Provider classes, utility functions for dealing with providers and re-exports many of the classes and types needed to implement a custom Provider.
For more information, see the documentation.
Most users will prefer to use the umbrella package, but for those with more specific needs, individual components can be imported.
