Cloud Security & IoT Hacking Guide

Complete guide to cloud security, IoT hacking, attack vectors, tools, and defense strategies.

☁️ 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:

☁️ AWS CLI S3 Enumeration

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

Tools: S3Scanner, BucketStream

B. Privilege Escalation

AWS IAM Misconfigurations:

☁️ AWS CLI IAM Enumeration

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:

🐳 Docker Container Escape

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 IoT Search

shodan search "default password"

Firmware Extraction:

🔧 Binwalk Firmware Analysis

binwalk -e firmware.bin

B. Exploitation

Brute-forcing Telnet/SSH:

🔑 Hydra Brute Force

hydra -l admin -P rockyou.txt 192.168.1.1 telnet

MQTT Exploitation:

📡 MQTT Subscribe

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:

☁️ AWS CLI Find Buckets

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

2. Download files:

☁️ AWS CLI Download

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

Lab 2: Exploiting IoT Camera

1. Find target:

🔍 Shodan Find Camera

shodan search "webcam"

Login with admin:admin
Access live feed via /video.mjpg

Conclusion

Cloud security requires configuration auditing
IoT hacking combines network + hardware attacks
Defense = encryption + segmentation + monitoring
