frida-remote-stream

Create an outbound stream over a message transport.

Example

$3

In your agent.js:

``js
const fs = require('frida-fs');
const RemoteStreamController = require('frida-remote-stream');

const controller = new RemoteStreamController();
controller.events.on('send', packet => {
send({
name: '+stream',
payload: packet.stanza
}, packet.data);
});
function onStreamMessage(message, data) {
controller.receive({ stanza: message.payload, data });

recv('+stream', onStreamMessage);
}
recv('+stream', onStreamMessage);

fs.createReadStream('/very/large/file').pipe(controller.open('filedump', { meta: 'data' }));
`

In your application:

`js
const fs = require('fs');
const RemoteStreamController = require('frida-remote-stream');

const controller = new RemoteStreamController();
controller.events.on('send', packet => {
script.post({
type: '+stream',
payload: packet.stanza
}, packet.data);
});
script.message.connect((message, data) => {
if (message.type === 'send') {
const stanza = message.payload;
switch (stanza.name) {
case '+stream':
controller.receive({ stanza: stanza.payload, data });
break;
}
}
});

controller.events.on('stream', stream => {
// stream.details.meta === 'data'

stream.pipe(fs.createWriteStream('/tmp/interesting-file'));
});
`

$3

In your agent.js:

`js
const fs = require('frida-fs');
const RemoteStreamController = require('frida-remote-stream');

const streams = new RemoteStreamController();
streams.on('send', (stanza, data) => {
send({
name: '+stream',
payload: stanza
}, data ? data.buffer : null);
});
function onStreamMessage(message, data) {
streams.receive(message.payload, data ? new Buffer(data) : null);

recv('+stream', onStreamMessage);
}
recv('+stream', onStreamMessage);

streams.on('stream', stream => {
stream.pipe(fs.createWriteStream('/very/large/file'));
});
`

In your application:

`js
const fs = require('fs');
const RemoteStreamController = require('frida-remote-stream');

const streams = new RemoteStreamController();
streams.on('send', (stanza, data) => {
script.post({
type: '+stream',
payload: stanza
}, data);
});
script.events.listen('message', (message, data) => {
if (message.type === 'send') {
const stanza = message.payload;
switch (stanza.name) {
case '+stream':
streams.receive(stanza.payload, data);
break;
}
}
});

fs.createReadStream('/tmp/interesting-file').pipe(streams.open('filedump', { meta: 'data' }));
