TLDR; Red Team Engagement for a telecom company. Got a foothold on the company’s Network Monitoring System (NMS). Sorted reverse shell issue with tunneling SSH over HTTP. Went full-on Ninja when getting SSH over HTTP. Proxied inside the network to get for internal network scan. Got access to CDRs and VLR with SS7 application.


Recap: Red Team Engagement for a Telecom company. Found interesting subdomain, did a full port scan on that subdomain, found port 12000/tcp, 14000/tcp, and 14100/tcp found a running instance of JBoss (lucky me!), exploited JBoss for RCE, implemented TCP tunnel over HTTP for Shell Stability.


In the previous part, I mentioned the steps I followed to create SSH Tunnels with stealthy SSH access from my server using port 2222/tcp. In this blog post, I’ll show how I used the SOCKS Tunnel for internal network reconnaissance and to exploit internal servers to get access to the CDRs stored in a server.


Situational Awareness (Internal Network)

During the engagement, I was able to create a Dynamic SSH tunnel via TCP tunnel over HTTP, and believe me when I say this, the shell was neat!

Moving forward, I then configured the SOCKS tunnel over port 9090/tcp and then connected proxychains for NMap scans.

Neural network: what is a neural network?

Neural networks, as their name implies, are computer algorithms modeled after networks of neurons in the human brain. Learn more about neural networks from Algorithmia.

A Comparative Analysis of Recurrent Neural Networks

Recurrent neural networks, also known as RNNs, are a class of neural networks that allow previous outputs to be used as inputs while having hidden states.

Recurrent Neural Networks for Multilabel Text Classification Tasks

The purpose of this project is to build and evaluate Recurrent Neural Networks(RNNs) for sentence-level classification tasks. Let's understand about recurrent neural networks for multilabel text classification tasks.
