PyPI Package Disguised as Instagram Growth Tool Harvests User Credentials
A deceptive PyPI package posing as an Instagram growth tool collects user credentials and sends them to third-party bot services.

quaff
requires Node.js 12.20.0 or later.
Assume a folder with this structure.
data/
mammals/
cats.json
dogs.json
bears.csv
birds/
parrots.yml
story.aml
After import
'ing quaff
:
import { load } from 'quaff';
const data = await load('./data/');
console.log(data);
And the results...
{
"mammals": {
"cats": ["Marty", "Sammy"],
"dogs": ["Snazzy", "Cally"],
"bears": [
{
"name": "Steve",
"type": "Polar bear"
},
{
"name": "Angelica",
"type": "Sun bear"
}
]
},
"birds": {
"parrots": {
"alive": ["Buzz"],
"dead": ["Moose"]
},
"story": {
"title": "All about birds",
"prose": [
{ "type": "text", "value": "Do you know how great birds are?" },
{ "type": "text", "value": "Come with me on this journey." }
]
}
}
}
As of 5.0.0
it's now possible to load a single file at a time, enabling more custom approaches in case load
doesn't work exactly the way you'd like.
import { loadFile } from 'quaff';
const data = await loadFile('./data/mammals/bears.csv');
console.log(data);
And the results...
[
{
"name": "Steve",
"type": "Polar bear"
},
{
"name": "Angelica",
"type": "Sun bear"
}
]
One of the biggest features added in quaff
4.0 is the ability to load JavaScript files. But how exactly does that work?
JavaScript files that are consumed by quaff
have to follow one simple rule - they must export default
a function, an async function or value. All three of these are valid and return the same value:
export default [
{
name: 'Pudge',
instagram: 'https://instagram.com/pudgethecorgi/',
},
];
export default () => [
{
name: 'Pudge',
instagram: 'https://instagram.com/pudgethecorgi/',
},
];
export default async () => [
{
name: 'Pudge',
instagram: 'https://instagram.com/pudgethecorgi/',
},
];
The final example above is the most interesting one - async
functions also work! This means you can write code to hit API endpoints, or do other asynchronous work, and quaff
will wait for those to resolve.
import fetch from 'node-fetch';
export default async () => {
const res = await fetch('https://my-cool-api/');
const data = await res.json();
// whatever the API returned will be added to the quaff object!
return data;
};
Don't have a Promise
to do async work with? Working with a callback interface? Just wrap it in one!
import {apiHelper } from 'my-callback-api';
export default () => {
return new Promise((resolve, reject) => {
apiHelper('people', (err, data) => {
if (err) return reject(err);
// quaff will take it from here!
resolve(data);
});
});
};
