Which attack exploits vulnerabilities in applications running on an organization's information system to steal or manipulate data or gain unauthorized access?

• A. Application Level Attack
• B. GCPBucketBrute
• C. Accessing nodes
• D. Shrink Wrap Code Attack

Answer: (A)

Attacks at the application layer exploit weaknesses in the software that runs on an organization’s systems—web apps, APIs, and enterprise applications—to steal or manipulate data or to bypass authentication and gain unauthorized access. This includes flaws in input validation, authentication/authorization, session management, and business logic that allow an attacker to exfiltrate data or alter how the application behaves.

That’s why this option is the best fit: it directly describes exploiting application software to achieve data theft, tampering, or unauthorized access.

The other terms describe different targets or unclear concepts. Brute-forcing access to cloud storage buckets targets cloud storage permissions rather than the application itself. Accessing nodes focuses on compromising hosts or network infrastructure rather than the application layer. Shrink Wrap Code Attack isn’t a standard, well-defined category for application vulnerabilities, so it doesn’t align with exploiting the software running the organization’s applications.
