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.
Heatmaps for node.js and the browser, groovy!
var heatmap = require('heatmap');
var heat = heatmap(500, 500, { radius : 30 });
for (var i = 0; i < 5000; i++) {
var rho = Math.random() * 2 * Math.PI;
var z = Math.pow(Math.random(), 2) * 200;
var x = 250 + Math.cos(rho) * z;
var y = 250 + Math.sin(rho) * z;
heat.addPoint(x, y);
}
heat.draw();
var fs = require('fs');
fs.writeFileSync('blob.png', heat.canvas.toBuffer());
var heatmap = require('heatmap');
Create a new heatmap from an existing canvas element, a numeric width and height, or an option object with canvas or width and height fields.
Optionally, you can set the opts.radius
and opts.threshold
to control the
rendering a little.
Add a point to the heatmap with a radius
.
params
can have:
Scale the canvas by the coefficients x
and y
.
If y
is undefined, scale both x and y by the first parameter, x
.
Render all the points onto the canvas element.
The HTML Canvas element.
Protip: with the canvas module for
node you can heat.canvas.buffer()
to get a Buffer with a PNG file all up in it.
With npm, just do:
npm install heatmap
