Introduction
In the fast-evolving landscape of cybersecurity, emerging threats pose an ever-growing challenge. Penetration testers need to be adaptive, agile, and continuously updated on the latest in malicious activities and exploit vectors. This article aims to explore some of the emerging threats and their implications for penetration testing. Armed with a better understanding, you can tailor your penetration testing methodologies to anticipate and counter these novel challenges effectively.
Ransomware-as-a-Service (RaaS)
What it is:
Ransomware attacks are nothing new, but the advent of Ransomware-as-a-Service has made it increasingly accessible for would-be attackers without the technical skills to develop ransomware from scratch. RaaS platforms often offer user-friendly interfaces and customer support, significantly lowering the entry barrier.
Implications for Penetration Testing:
- File System and Backup Audits: During your penetration tests, focus on auditing file systems and backup solutions to ensure they can withstand ransomware attacks.
- Phishing Simulations: Most RaaS attacks are initiated through phishing. Conduct phishing simulation tests to educate employees and evaluate organizational readiness.
Proof of Concept:
For simulating a ransomware attack, you can use tools like `Mimikatz` to harvest credentials and use PowerShell scripts to encrypt certain directories (Figure 1).

Cloud Security Misconfigurations
What it is:
As organizations move to the cloud, attackers are exploiting poorly configured cloud resources. This includes insecure S3 buckets, poorly configured firewalls, and exposed API keys.
Implications for Penetration Testing:
- Cloud Infrastructure Assessment: Perform an in-depth assessment of the cloud services in use, focusing on IAM roles, firewall configurations, and exposed resource.
- Automated Scanning: Implement automated scanners to identify misconfigurations in real-time.
Proof of Concept:
You can use the `aws-cli` or tools like `ScoutSuite` for auditing AWS configurations.

Supply Chain Attacks
What it is:
In a supply chain attack, an attacker compromises the software supply chain to insert malicious code into legitimate software or systems.
Implications for Penetration Testing:
- Software Inventory: Know all third-party software and components that are part of your environment.
- Integrity Checks: Regularly conduct integrity checks on these components.
Proof of Concept:
You can use checksums to ensure the integrity of third-party software packages.

Conclusion
Emerging threats will continue to evolve, and penetration testers must adapt accordingly. These adaptations involve both broadening the scope of standard penetration testing and diving deeper into specialized areas. Only then can we maintain a strong defense against the attackers of tomorrow.
