The presentation discusses the vulnerabilities of SMB protocol and the importance of implementing encryption and signing to protect against attacks.
- SMB protocol is vulnerable to attacks if encryption and signing are not implemented
- Attackers can inject fake files and directories, replace legitimate files with links that execute their code, and steal copies of files passed over the network
- SMB version 1 does not use signing or encryption by default, while SMB version 2 and 3 support encryption but it is not enabled by default
- Enabling encryption and signing is important to protect against attacks
- Organizations should require encryption and signing to be enabled
The presenter demonstrated how an attacker can inject fake files and directories and replace legitimate files with links that execute their code. They also showed how SMB version 1 does not use signing or encryption by default, making it vulnerable to attacks. The presenter emphasized the importance of enabling encryption and signing to protect against these types of attacks.
