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.
ethereumjs-block
Advanced tools
The ethereumjs-block npm package is a library for creating, manipulating, and validating Ethereum blocks. It is part of the EthereumJS project, which provides a suite of libraries for working with the Ethereum protocol in JavaScript.
Creating a new block
This feature allows you to create a new Ethereum block instance. The code sample demonstrates how to import the Block class from the ethereumjs-block package and create a new block.
const Block = require('ethereumjs-block');
const block = new Block();
console.log(block);
Validating a block
This feature allows you to validate an Ethereum block. The code sample shows how to create a block and then validate it using the validate method.
const Block = require('ethereumjs-block');
const block = new Block();
block.validate((err, valid) => {
if (err) {
console.error('Block validation failed:', err);
} else {
console.log('Block is valid:', valid);
}
});
Serializing a block
This feature allows you to serialize an Ethereum block into a Buffer. The code sample demonstrates how to create a block and then serialize it to a hexadecimal string.
const Block = require('ethereumjs-block');
const block = new Block();
const serializedBlock = block.serialize();
console.log(serializedBlock.toString('hex'));
Deserializing a block
This feature allows you to deserialize a serialized block back into a Block instance. The code sample shows how to take a serialized block in hexadecimal format and convert it back into a Block object.
const Block = require('ethereumjs-block');
const serializedBlock = '...'; // some serialized block data
const block = Block.fromRLPSerializedBlock(Buffer.from(serializedBlock, 'hex'));
console.log(block);
The ethereumjs-tx package is used for creating, manipulating, and signing Ethereum transactions. While ethereumjs-block focuses on blocks, ethereumjs-tx is specialized in handling transactions within those blocks.
The web3 package is a comprehensive library for interacting with the Ethereum blockchain. It provides functionalities for working with blocks, transactions, smart contracts, and more. Compared to ethereumjs-block, web3 offers a broader range of features but may be more complex to use for block-specific operations.
The ethers package is another library for interacting with the Ethereum blockchain. It is known for its simplicity and ease of use. Like web3, it provides a wide range of functionalities, including working with blocks and transactions. It is a good alternative if you need a more user-friendly API.
Implements schema and functions related to Ethereum's block.
