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.
eventregistry
Advanced tools
This library contains classes that allow one to easily access the event and article information from Event Registry (http://eventregistry.org).
Most of the package is quite similar to Event Registry Python so for all who are already acquainted with the Python version, there shouldn't be any problems with using this package. Though we strongly suggest using a JS transpiler or Typescript to employ the latest in ECMAScript standards.
Event Registry package can be installed using the NodeJS Package Manager. Type the following in the command line:
npm install eventregistry
and the package should be installed. Alternatively, you can also clone the package from the GitHub repository. After cloning it, open the command line and run:
npm build
If you are using Typescript then import the package with the following line:
import {EventRegistry} from "eventregistry";
const er = new EventRegistry();
If you are using Node.js with no ES6 support.
var erBase = require("eventregistry");
var er = new erBase.EventRegistry();
Or shorter with destructuring, which is available from Node.js v6 onwards.
const { EventRegistry } = require("eventregistry");
const er = new EventRegistry();
As features are added to the package you will need at some point to update it. In case you have downloaded the package from GitHub simply do a git pull
. If you have installed it using the npm
command, then simply run:
npm update eventregistry
When making queries to Event Registry you will have to use an API key that you can obtain for free.
Print a list of recently added articles mentioning George Clooney
var erBase = require("eventregistry");
var er = new erBase.EventRegistry({apiKey: "YOUR_API_KEY"});
er.getConceptUri("George Clooney").then((conceptUri) => {
var q = new erBase.QueryArticlesIter(er, {conceptUri: conceptUri, sortBy: "date"});
q.execQuery((item) => {
console.info(item);
})
});
Or in Typescript.
import {EventRegistry, QueryArticlesIter} from "eventregistry";
const er = new EventRegistry({apiKey: "YOUR_API_KEY"});
er.getConceptUri("George Clooney").then((conceptUri) => {
const q = new QueryArticlesIter(er, {conceptUri: conceptUri, sortBy: "date"});
q.execQuery((item) => {
console.info(item);
})
});
Alternative approach in Typescript using the new ES6 async/await
pattern.
import {EventRegistry, QueryArticlesIter} from "eventregistry";
const er = new EventRegistry({apiKey: "YOUR_API_KEY"});
async function iterateOverArticles() {
const q = new QueryArticlesIter(er, {conceptUri: await er.getConceptUri("George Clooney"), sortBy: "date"});
q.execQuery((item) => {
console.info(item);
})
}
iterateOverArticles();
Search for latest events related to Star Wars
var erBase = require("eventregistry");
var er = new erBase.EventRegistry({apiKey: "YOUR_API_KEY"});
er.getConceptUri("Star Wars").then((conceptUri) => {
var q = new erBase.QueryEvents({conceptUri: conceptUri});
var requestEventsInfo = new erBase.RequestEventsInfo({sortBy: "date", count: 10});
q.setRequestedResult(requestEventsInfo);
return er.execQuery(q);
}).then((response) => {
console.info(response);
});
Or in Typescript.
import {EventRegistry, QueryEvents, RequestEventsInfo} from "eventregistry";
const er = new EventRegistry({apiKey: "YOUR_API_KEY"});
er.getConceptUri("Star Wars").then((conceptUri) => {
const q = new QueryEvents({conceptUri: conceptUri});
const requestEventsInfo = new RequestEventsInfo({sortBy: "date", count: 10});
q.setRequestedResult(requestEventsInfo);
return er.execQuery(q);
}).then((response) => {
console.info(response);
});
Alternative approach using the new ES6 async/await
pattern.
import {EventRegistry, QueryEvents, RequestEventsInfo} from "eventregistry";
const er = new EventRegistry({apiKey: "YOUR_API_KEY"});
async function iterateOverEvents() {
const q = new QueryEvents({conceptUri: await er.getConceptUri("Star Wars")});
const requestEventsInfo = new RequestEventsInfo({sortBy: "date", count: 10});
q.setRequestedResult(requestEventsInfo);
return er.execQuery(q);
}
iterateOverEvents();
What are the currently trending topics
var erBase = require("eventregistry");
var er = new erBase.EventRegistry({apiKey: "YOUR_API_KEY"});
var q = new erBase.GetTrendingConcepts({source: "news", count: 10});
er.execQuery(q).then((response) => {
console.info(response);
});
Or in Typescript.
import {EventRegistry, GetTrendingConcepts} from "eventregistry";
const er = new EventRegistry({apiKey: "YOUR_API_KEY"});
const q = new GetTrendingConcepts({source: "news", count: 10});
er.execQuery(q).then((response) => {
console.info(response);
});
Search for duplicated articles in Business
var erBase = require("eventregistry");
var er = new erBase.EventRegistry({apiKey: "YOUR_API_KEY"});
er.getCategoryUri("business").then((categoryUri) => {
var q = new erBase.QueryArticles({
categoryUri: categoryUri,
isDuplicateFilter: "keepOnlyDuplicates", // possible values are "skipDuplicates" or "keepOnlyDuplicates" or "keepAll";
});
return er.execQuery(q);
}).then((response) => {
console.log(response);
});
Or in Typescript.
import {EventRegistry, QueryArticles} from "eventregistry";
const er = new EventRegistry({apiKey: "YOUR_API_KEY"});
er.getCategoryUri("business").then((businessUri) => {
const q = new QueryArticles({
categoryUri: businessUri,
isDuplicateFilter: "keepOnlyDuplicates", // possible values are "skipDuplicates" or "keepOnlyDuplicates" or "keepAll";
});
return er.execQuery(q);
}).then((response) => {
console.log(response);
});
