Check for the CRIME vulnerability
If the result is positive, there is no need for further action. If the result is negative, please read the following instructions.
| Result positive | Not vulnerable to Crime |
| Result negativ | Vulnerable to Crime |
| Description | The server is vulnerable to Crime. This allows an attacker to decode the communication. |
| Background | The CRIME attack takes advantage of the fact that data compression can change the length of encrypted messages, and this provides conclusions about the plain text. This can be used by a skilled attacker to steal cookies, for example. |
| Consequence | The server is vulnerable through a security flaw that allows an attacker to decrypt the communication. |
| Solution/Tips | CRIME can be prevented by disabling the use of compression of data in TLS. Disable TLS Compression on your server. |
