**Cloud hacking** is defined as the unauthorized access to the cloud computing system, network, or service. The cloud environment is becoming very popular among businesses and individuals for its convenience, scalability, and flexibility. However, this has also made cloud systems attractive targets for cybercriminals. Attackers exploit vulnerabilities in cloud services or misconfigurations to gain unauthorized access to sensitive data, applications, or infrastructure hosted on the cloud.
Below is the explanation of **cloud hacking**, how it occurs, attack vectors, and techniques.

### **How Cloud Hacking Occurs**
Cloud hacking normally takes advantage of vulnerabilities in the following categories:
1. **Weak Authentication and Access Control**
- Passwords: Weak or easy-to-guess passwords are especially dangerous when the same password is used on different services.
- **Multi-Factor Authentication (MFA) Bypass**: MFA is a robust security practice. However, it can be bypassed using social engineering attacks, SIM swapping, and by exploiting weak configurations.
- **Insecure APIs**: Many cloud services allow integration and automation via APIs. If the APIs are not secured appropriately-often with strong authentication and/or encryption-they will represent an entry point to an attacker.
2. **Misconfigurations
- **Cloud Storage Buckets**: Cloud storage buckets (such as Amazon S3 or Google Cloud Storage) should not be left open to the public since this makes it easy for attackers to view and download sensitive information or change the data they have.
- **Incorrect Permissions**: While many cloud services allow fine-grained access control, setting incorrect permissions, such as providing more access than actually required, can provide unauthorized access to critical resources.
- **Publicly Available Management Interfaces**: Many of the cloud services provide management consoles that are web accessible. If such consoles have been exposed to the Internet without proper security controls in place, they can prove easy targets for attackers.
3. **Cloud Software or Services Vulnerabilities**
- **Unpatched Software**: Cloud services and software are often vulnerable. If they are not updated regularly, attackers can exploit them to compromise cloud resources.
- **Container Vulnerabilities**: Containers, including Docker or Kubernetes, are widely used in cloud environments. Misconfigurations or flaws in container orchestration systems can expose systems to attacks.
- **Shared Responsibility Model**: Cloud providers and users share the responsibility for securing cloud resources. However, confusion or negligence about which party is responsible for specific security measures can lead to vulnerabilities.
4. **Phishing and Social Engineering**
- **Phishing Attacks**: Attackers may use phishing tactics to trick cloud service users into providing their login credentials. Once they have the credentials, they can access cloud accounts.
- **Business Email Compromise (BEC)**: Hackers may assume the identity of a legitimate business email to coerce victims into surrendering credentials or other sensitive information regarding cloud resources.

### **Common Cloud Hacking Attack Vectors**
Here are some common methods hackers use to gain access to cloud environments:
1. **Brute-Force Attacks**
- Hackers can employ automated tools to guess weak passwords and gain unauthorized access to cloud services. This is most effective when MFA is not enabled or when password policies are weak.
2. **Exploiting Misconfigurations**
- Attackers often scan for improperly configured cloud resources, such as storage buckets or databases, that are left publicly accessible. Tools like **Shodan** or **Censys** can be used to search for exposed cloud resources.
- Publicly accessible cloud storage buckets may contain sensitive information, including login credentials, personal data, and proprietary business information.
3. **Credential Stuffing**
- Attackers use credentials, most of which are obtained from previous data breaches, to try and log into cloud services. They may use large databases of known username/password pairs and test them on popular cloud platforms.
4. **API Exploits
- APIs are so favored because they frequently offer direct access to cloud services from programs. If the API is not well secured or authenticated and encrypted, hackers could use the API as leverage to get into your confidential data or execute bad or malicious behavior.
Insecure APIs may, for example, enable the attack to obtain access to computation resources, databases, and even to control the privilege of an administrator.
5. **DoS Attacks**
These include DoS or DDoS attacks, that floods the cloud infrastructure with traffic, hence making cloud services unavailable to legitimate users. Attackers can try to compromise the underlying infrastructure and disrupt the availability of applications based in the cloud.
6. **Inside Threats**
- An inside attacker with ill motives - either a disgruntled employee or contractor may abuse the cloud environment by attempting unauthorized access or exposing confidential data. The attacks through insider threat are so severe, considering that they mostly rely on trusted access within cloud systems.

### Cloud Hacking Hacker Techniques
1. **Privilege Escalation**
- After initial access, they can try to elevate their privileges either for admin-level control over the cloud infrastructure or to gain access to more sensitive resources. They might achieve this by exploiting misconfigurations, weak access controls, or vulnerabilities in the cloud platform.
2. Data Exfiltration
- As soon as the attacker gains cloud systems, it may try to capture some sensitive data. The exfiltration of data is the process of copying and transferring large amounts of data or uploading it into a server controlled by an attacker.
3. Lateral Movement
- After initial compromise, attackers may laterally move through the cloud network using compromised accounts, misconfigured systems, or weak network security to access other parts of the infrastructure.
4. **Use of Malicious Cloud Resources
- Hackers can set up their own cloud resources within a compromised cloud environment (e.g., spinning up virtual machines, using compute power for cryptocurrency mining, etc.). This can lead to financial and operational damage to the legitimate cloud users.

### **Notable Cloud Hacking Incidents**
1. **Capital One Data Breach (2019)**
- A third-party cloud service provider employee used a configuration error of Capital One's cloud infrastructure to access sensitive data of their customers, among which was credit card application. More than 100 million users in the U.S and Canada were compromised.
2. **Code Spaces (2014)**
- A cloud-based code hosting service, **Code Spaces**, was hacked and shut down after an attacker gained access to the company's AWS infrastructure and deleted critical data and backups. The attacker gained access via insecure credentials and had full control over the cloud resources.
3. **Tesla Cloud Attack (2018)**
- Hackers accessed Tesla's AWS cloud environment to mine cryptocurrencies using Tesla's cloud infrastructure. The attackers accessed it using misconfigured cloud servers without permission from Tesla.

### Best Practices for Prevention of Cloud Hacking and Enhancing Cloud Security
To prevent cloud hacking and enhance the security of the cloud environment, organizations and cloud users should implement these best practices:
1. **Enable Multi-Factor Authentication (MFA)**
- Use MFA for all cloud accounts for that added layer of security above and beyond a simple password.
2. **Audit Cloud Resources Periodically**
Conduct security audits of cloud configurations periodically to ensure that they comply with best practices and don't expose sensitive resources.
3. **Implement Robust Access Controls
- Implement the principle of least privilege (PoLP) by restricting access to cloud resources only to those who need it and ensuring proper role-based access control (RBAC) is in place.
4. **Patch and Update Cloud Software Regularly**
- Keep cloud applications, services, and APIs updated to prevent known vulnerabilities from being exploited.
5. **Encrypt Sensitive Data**
- Use strong encryption for data both at rest and in transit to prevent unauthorized access to sensitive information.
6. **Secure APIs**
- Ensure that APIs used to access cloud services are properly authenticated, encrypted, and configured to only allow necessary access.
7. **Monitor and Respond to Security Events**
- Have cloud activity monitored and logged continuously to quickly identify unusual behavior or security incidents.

### Conclusion
Cloud hacking is becoming increasingly widespread with more organizations and individuals putting their data and services into the cloud. Cloud platforms may be highly flexible but offer challenges that are peculiarly related to security issues. Hackers tend to seek access to unauthorized clouds via weak authentication, poor configurations, and vulnerabilities within the services offered by cloud services. By adhering to the best practices in securing a cloud, an organization is assured of reducing the probability of hacking and ensuring safe guarding sensitive data and applications from such hacks.
