Quasar RAT Disguised as an npm Package for Detecting Vulnerabilities in Ethereum Smart Contracts
Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
xsalsa20-encoding
Advanced tools
XSalsa20 codec that implements that abstract-encoding interface. Nonces are generated randomly and prepended to the ciphertext.
$ npm install xsalsa20-encoding
const codec = require('xsalsa20-encoding')(secretKey)
// encode a value
buffer = codec.encode(value)
// decode a value
value = codec.decode(buffer)
const crypto = require('crypto')
const Codec = require('xsalsa20-encoding')
const key = crypto.randomBytes(32)
const codec = Codec(key)
const hello = codec.encode('hello')
const world = codec.encode('world')
console.log('%s %s', codec.decode(hello), codec.decode(world)) // 'hello world'
const pbs = require('protocol-buffers')
const { Message } = pbs(`
message {
string data = 1;
}
`)
const codec = Codec(key, { valueEncoding: Message })
const encoded = codec.encode({ data: 'hello world' })
const message = codec.decode(encoded) // { data: 'hello world' }
codec = require('xsalsa20-encoding')([secretKey[, opts])
Create a codec object from 32 byte secretKey
.
const key = crypto.randomBytes(32)
const codec = Codec(key)
buffer = codec.encode(value[, output[, offset]])
Encode a value using xsalsa20
(XOR) into an optional output
buffer at an optional offset
defaulting to 0
. If an output
buffer is not given, one is allocated
for you and returned.
const buffer = codec.encode('hello world')
value = codec.decode(buffer[, offset])
Decode a buffer using xsalsa20
(XOR) at an optional offset
defaulting to 0
.
const value = codec.decode(buffer)
length = codec.encodingLength(value)
Returns the encoding length for a given value
.
const length = codec.encodingLength('hello world') // 35
