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.

Advanced tools
Parameters
ens
node
contract
resolverAddress returns the address of the resolver.
Returns any A promise for the address of the resolver.
reverseAddr looks up the reverse record for the address returned by the resolver's addr()
Returns any A promise for the Resolver for the reverse record.
abi returns the ABI associated with the name. Automatically looks for an ABI on the reverse record if none is found on the name itself.
Parameters
Optional.null
bool If false, do not look up the ABI on the reverse entry.reverse
Returns object A promise for the contract ABI.
contract returns a web3 contract object. The address is that returned by this resolver's
addr()
, and the ABI is loaded from this resolver's ABI()
method, or the ABI on the
reverse record if that's not found. Returns null if no address is specified or no ABI
was found. The returned contract object will not be promisifed or otherwise modified.
Returns object A promise for the contract instance.
Provides an easy-to-use interface to the Ethereum Name Service.
Example usage:
var ENS = require('ethereum-ens');
var Web3 = require('@danielsmilo/web3');
var provider = new Web3.providers.HttpProvider();
var ens = new ENS(provider);
var address = ens.resolver('foo.eth').addr().then(function(addr) { ... });
Functions that require communicating with the node return promises, rather than
using callbacks. A promise has a then
function, which takes a callback and will
call it when the promise is fulfilled; then
returns another promise, so you can
chain callbacks. For more details, see http://bluebirdjs.com/.
Notably, the resolver
method returns a resolver instance immediately; lookup of
the resolver address is done in the background or when you first call an asynchronous
method on the resolver.
Functions that create transactions also take an optional 'options' argument; this has the same parameters as web3.
Parameters
provider
object A web3 provider to use to communicate with the blockchain.address
address Optional. The address of the ENS registry. Defaults to the public ENS registry.Meta
resolver returns a resolver object for the specified name, throwing
ENS.NameNotFound if the name does not exist in ENS.
Resolver objects are wrappers around web3 contract objects, with the
first argument - always the node ID in an ENS resolver - automatically
supplied. So, to call the addr(node)
function on a standard resolver,
you only have to call addr()
. Returned objects are also 'promisified' - they
return a Bluebird Promise object instead of taking a callback.
Parameters
name
string The name to look up.abi
list Optional. The JSON ABI definition to use for the resolver.
if none is supplied, a default definition implementing has
, addr
, name
,
setName
and setAddr
is supplied.Returns any The resolver object.
reverse returns a resolver object for the reverse resolution of the specified address,
throwing ENS.NameNotFound if the reverse record does not exist in ENS.

Parameters
address

list Optional. The JSON ABI definition to use for the resolver.
if none is supplied, a default definition implementing has
, addr
, name
,
setName
and setAddr
is supplied.Returns any The resolver object.
setResolver sets the address of the resolver contract for the specified name. The calling account must be the owner of the name in order for this call to succeed.
Parameters
name
string The name to updateaddress
address The address of the resolveroptions
object An optional dict of parameters to pass to web3.addr
params
Returns any A promise that returns the transaction ID when the transaction is mined.
owner returns the address of the owner of the specified name.
Parameters
name
string The name to look up.callback
Returns any A promise returning the owner address of the specified name.
setOwner sets the owner of the specified name. Only the owner may call setResolver or setSubnodeOwner. The calling account must be the current owner of the name in order for this call to succeed.
Parameters
name
string The name to updateaddress
address The address of the new owneroptions
object An optional dict of parameters to pass to web3.addr
params
Returns any A promise returning the transaction ID of the transaction, once mined.
setSubnodeOwner sets the owner of the specified name. The calling account must be the owner of the parent name in order for this call to succeed - for example, to call setSubnodeOwner on 'foo.bar.eth', the caller must be the owner of 'bar.eth'.
Parameters
name
string The name to updateaddress
address The address of the new owneroptions
object An optional dict of parameters to pass to web3.addr
params
Returns any A promise returning the transaction ID of the transaction, once mined.
