I wonder how vulnerable are Sweet32 and Lucky13? I mean, how often do the attackers use these vulnerabilities to gain access?
Lucky13 and Sweet32 are both attacks on SSL/TLS, i.e. these attacks can be used to intercept the encrypted connection between the client and the server. In the case of a server that is vulnerably to Lucky13, an active attacker may be able to launch a MITM attack by exploiting this vulnerability. The same applies to Sweet32, but even a passive attacker may be able to decrypt the encrypted data if they are able to collect enough data. However, neither attack can be used to gain access to the server.
