Cloudborne Attack on Bare-Metal Firmware
Short answer
A Cloudborne attacks exploit infrastructure vulnerabilities like firmware flaws to implant persistent backdoors in bare-metal cloud servers.
Question
Thomas, a cloud security professional, is performing security assessment on cloud services to identify any loopholes. He detects a vulnerability in a bare-metal cloud server that can enable hackers to implant malicious backdoors in its firmware. He also identified that an installed backdoor can persist even if the server is reallocated to new clients or businesses that use it as an IaaS. What is the type of cloud attack that can be performed by exploiting the vulnerability discussed in the above scenario?
Key Takeaways
The exam tests knowledge of attack vectors targeting physical cloud infrastructure, with the common trap being confusion between network-level hijacking (MITC) and infrastructure-level compromise (Cloudborne).
This question addresses cloudborne attacks, which exploit vulnerabilities in the underlying infrastructure of cloud services to implant persistent backdoors. It establishes that such attacks target bare-metal servers and can survive instance reallocation.
Common mistake: Candidates often select Man-in-the-cloud (MITC), confusing it with session hijacking or proxy-based interception rather than a low-level firmware persistence attack.
Expert Analysis
Why the Answer Is Correct
A cloudborne attack specifically targets the underlying infrastructure of a cloud service provider, such as hypervisors or bare-metal servers. By exploiting vulnerabilities in these components—often firmware—a malicious actor can implant persistent backdoors that survive across tenant boundaries and server reclamation processes.Why the Other Options Are Wrong
Man-in-the-cloud (MITC) involves intercepting traffic through compromised proxies or SSO tokens, not hardware firmware. Metadata spoofing relates to falsifying data attributes, while cryptojacking is about unauthorized computation usage. None of these describe the specific act of implanting a persistent firmware backdoor on a bare-metal server.Community Comment Notes
Community consensus strongly supports this answer, noting that cloudborne attacks involve compromising underlying infrastructure like firmware. As one user noted, 'Cloudborne IaaS Attack Allows Persistent Backdoors in the Cloud,' highlighting the persistence aspect mentioned in the scenario.Exam Strategy
Focus on distinguishing between attacks that target the control plane or application layer versus those that target the physical or virtualized infrastructure itself.
Frequently Asked Questions
Why isn't this a Man-in-the-cloud attack?
MITC focuses on intercepting sessions via proxies or SSO compromises, whereas this scenario describes a deep infrastructure compromise at the firmware level.
Can a backdoor persist after reallocation?
Yes, if the backdoor is implanted in the firmware or hypervisor layer, it remains on the physical hardware regardless of how many times the logical server is recreated.

prasoonmk 👍 1 Answered ACloudborne IaaS Attack Allows Persistent Backdoors in the Cloud A known vulnerability combined with a weakness in bare-metal server reclamation opens the door to powerful, high-impact attacks. An attack scenario affecting various cloud providers could allow an attacker to implant persistent backdoors for data theft into bare-metal cloud servers, which would be able to remain intact as the cloud infrastructure moves from customer to customer. This opens the door to a wide array of attacks on businesses that use infrastructure-as-a-service (IaaS) offerings.
