Malicious npm Packages Inject SSH Backdoors via Typosquatted Libraries
Socket’s threat research team has detected six malicious npm packages typosquatting popular libraries to insert SSH backdoors.

Advanced tools
On the Cardano blockchain, native assets are uniquely identified by both their policy id and asset name. Neither the policy id nor the asset name are intended to be human-readable data. CIP14 introduces an asset fingerprint which is a short(er) and human-readable identifier for assets that user can recognize and refer to when talking about assets.
More specifically, CIP14 defines a user-facing asset fingerprint as a bech32-encoded blake2b-160 digest of the concatenation of the policy id and the asset name.
This package is a Typescript implementation of CIP14
npm i @emurgo/cip14-js --save
const AssetFingerprint = require('@emurgo/cip14-js');
// initialize class with policyId, assetName
const assetFingerprint = AssetFingerprint.fromParts(
Buffer.from('1e349c9bdea19fd6c147626a5260bc44b71635f398b67c59881df209', 'hex'),
Buffer.from('504154415445', 'hex'),
);
const fingerprintHash = assetFingerprint.hash();
const bech32Fingerprint = assetFingerprint.fingerprint();
// initialize class with bech32
const assetFingerprint = AssetFingerprint.fromBech32('asset1rjklcrnsdzqp65wjgrg55sy9723kw09mlgvlc3');
const fingerprintHash = assetFingerprint.hash();
const prefix = assetFingerprint.prefix();
