Signature Spoofing by Improper Validation |
|
|
| 摘要 |
An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key. |
| 前置条件 |
Recipient is using a weak cryptographic signature verification algorithm or a weak implementation of a cryptographic signature verification algorithm, or the configuration of the recipient's application accepts the use of keys generated using cryptographically weak signature verification algorithms. |
| 解决方案 | Use programs and products that contain cryptographic elements that have been thoroughly tested for flaws in the signature verification routines. |

描述
|
| CAPEC-473 |
An attacker generates a message or datablock that causes the recipient to believe that the message or datablock was generated and cryptographically signed by an authoritative or reputable source, misleading a victim or victim operating system into performing malicious actions. |
| CAPEC-542 |
An adversary develops targeted malware that takes advantage of a known vulnerability in an organizational information technology environment. The malware crafted for these attacks is based specifically on information gathered about the technology environment. Successfully executing the malware enables an adversary to achieve a wide variety of negative technical impacts. |
