Cloud Security & IoT Hacking

Part 1: Cloud Security

1. Introduction to Cloud Security

Cloud security is the part of cybersecurity career. Cloud security focuses on protecting data, applications, and infrastructure in cloud environments (AWS, Azure, GCP). Major risks include:

- Misconfigurations (Exposed S3 buckets)

- Insecure APIs

- Account hijacking

- Insider threats


2. Cloud Attack Vectors

A. Storage Bucket Exploitation

- AWS S3 Bucket Enumeration :

  bash

     aws s3 ls s3://bucket-name --no-sign-request    

 Tools : S3Scanner  ,  BucketStream


B. Privilege Escalation

- AWS IAM Misconfigurations :

  bash

    aws iam list-users    

    aws iam list-roles    

  

Tools : Pacu , CloudBrute


C. Serverless (Lambda) Attacks

- Injection in Lambda functions

Tools : Lambda-Proxy , AWS CLI


D. Container & Kubernetes Hacking

- Escaping Docker containers :

  bash

  docker run --privileged -it alpine    

  Tools :  kube-hunter ,  Peirates


3. Cloud Security Tools

| Tool      |     Purpose |

|-----      -|      ---------|

|   ScoutSuite   | Multi-cloud auditing |

|    CloudSploit | AWS/GCP/Azure security checks |

|      Terrascan | IaC (Terraform) security scanner |

|     Kubescape | Kubernetes security |


Part 2: IoT Hacking

1. IoT Attack Surface

- Firmware vulnerabilities

- Insecure APIs (MQTT, CoAP)

- Default credentials ( admin:admin )

- Hardware attacks (UART, JTAG)


2. IoT Hacking Methodology

A. Reconnaissance

-Shodan/FoFa Search :

      shodan search "default password"      

- Firmware Extraction :

  bash

      binwalk -e firmware.bin       

B. Exploitation

- Brute-forcing Telnet/SSH :

  bash

      hydra -l admin -P rockyou.txt 192.168.1.1 telnet        

 -MQTT Exploitation :

  bash

  mosquitto_sub -t "#" -h 192.168.1.100     


C. Hardware Hacking

- UART Pin Extraction :

  - Identify TX/RX/GND pins

  - Connect via USB-to-TTL adapter

- JTAG Debugging :

  - Use  OpenOCD ,  UrJTAG


3. IoT Security Tools

|    Tool   |     Purpose |

|------      |       ---------|

|   Firmware Analysis Toolkit (FAT) | Automated firmware analysis |

| RouterSploit   | IoT exploitation framework |

|   Wireshark     | Network protocol analysis |

|  JTAGulator    | Hardware debugging |


Part 3: Defense Strategies

Cloud Security Best Practices

✔ Enable MFA for all cloud accounts  

✔ Use IAM roles instead of root keys  

✔ Encrypt S3 buckets & EBS volumes  

✔ Monitor with AWS GuardDuty/Azure Sentinel  


IoT Security Best Practices

✔ Change default credentials  

✔ Disable unused services (Telnet)  

✔ Implement firmware signing  

✔ Use VLANs to segment IoT devices  


Hands-On Labs

Lab 1: Hacking an AWS S3 Bucket

1. Find open buckets:

   bash

      aws s3 ls s3:// --no-sign-request      

2. Download files:

   bash

   aws s3 cp s3://bucket-name/file.txt      


Lab 2: Exploiting IoT Camera

1. Find target:

   bash

   shodan search "webcam"

   2. Login with admin:admin

3. Access live feed via /video.mjpg


Conclusion

- Cloud security requires configuration auditing  

- IoT hacking combines network + hardware attacks  

- Defense = encryption + segmentation + monitoring


🔹 Next Steps :  

Module 11: Post-Exploitation & Reporting

- Try  AWS CTF challenges (CloudGoat)  

- Explore IoT villages at DEFCON  

- Learn hardware reverse engineering

Bug Bounty Hunter – The Professional Vulnerability Hunter

A Bug Bounty Hunter is a cybersecurity researcher who finds and reports security flaws in websites, apps, and systems in exchange for cash rewards (bounties) from companies like Google , Facebook , and Uber.  💰 How Bug Bounties Work    1. Target Selection – Choose a program (e.g., HackerOne, Bugcrowd).   2. Recon & Testing – Hunt for vulnerabilities (e.g., SQLi, XSS, RCE).   3. Submit a Report – Document the bug with PoC (Proof of Concept).   4. Get Paid – Rewards range from  $50 to $500,000+ per bug.   You can download book from here 🔥 Top Bug Bounty Platforms  |    Platform     |     Popular Programs   |    Avg. Payout |   |-------------|---------------------|------------|   |    HackerOne   | Uber, Twitter, GitHub | $500–$20K |   |     Bugcrowd    | AWS, Tesla, Cisco | $300–$15K | ...

Vulnerability Assessor – The Proactive Security Specialist

A Vulnerability Assessor is a cybersecurity professional who identifies, classifies, and prioritizes security weaknesses in systems, networks, and applications before attackers exploit them. Unlike penetration testers (who exploit flaws), assessors focus on discovery and risk analysis.  🔍 Core Responsibilities 1. Vulnerability Scanning       - Run automated scans (Nessus, Qualys, OpenVAS).      - Identify CVEs, misconfigurations, and outdated software.   2. Risk Assessment & Prioritization       - Rate vulnerabilities using CVSS scores.      - Focus on critical risks (e.g., RCE, SQLi).   3. Compliance Auditing     - Check adherence to PCI DSS, HIPAA, NIST.   4. Reporting & Remediation Guidance    - Provide actionable fixes (patching, hardening).  Key Tools & Technologies                ...

Red Teamer – The Elite Offensive Security Role

A Red Teamer is an advanced cybersecurity professional who simulates real-world attacks like advanced threat actors (APT groups, nation-states) to test an organization's defenses. Unlike penetration testers (who focus on finding vulnerabilities), Red Teams emulate stealthy, targeted attacks to evade detection.   🔥 Core Responsibilities   1. Adversary Emulation    - Mimic real APTs (MITRE ATT&CK framework).      - Use custom malware, C2 frameworks (Cobalt Strike, Sliver).   2. Physical & Social Engineering      - Phishing, USB drops, impersonation attacks.   3. Evasion & Lateral Movement      - Bypass EDR/XDR, AV, and SIEM detection.      - Privilege escalation, domain persistence.   4. Reporting & Purple Teaming      - Help Blue Team improve detection rules.  🛠️ Top Red Team Tools |   Category...
