What type of attack is caused by insecure or obsolete encryption in cloud services?

The type of attack associated with insecure or obsolete encryption in cloud services is cryptanalysis. Cryptanalysis involves the study and techniques used to decode encrypted data without access to the secret key, often exploiting weaknesses in the encryption method or outdated algorithms.

When encryption methods are weak or outdated, attackers can apply cryptanalysis techniques to decipher the encrypted data, potentially gaining access to sensitive information stored in cloud services. This highlights the importance of using strong, up-to-date encryption protocols to protect data in transit and at rest.

The other options refer to different types of attack methods. For instance, SQL Injection is a web application attack technique aimed at attacking data-driven applications by exploiting vulnerabilities in SQL query execution. Wrapping is a less common attack that involves hidden data or malicious code wrapped within legitimate-looking requests, typically in the context of token-based authentication or APIs. Denial of Service (DoS) attacks are aimed at making a service unavailable by overwhelming it with traffic or requests, which is unrelated to the topic of encryption weaknesses.
