Is SMB protocol Secure?
SMB Encryption provides end-to-end encryption of SMB data and protects data from eavesdropping occurrences on untrusted networks. You can deploy SMB Encryption with minimal effort, but it may require small additional costs for specialized hardware or software.
Which protocol was responsible for the WannaCry ransomware attack?
WannaCry was spread by EternalBlue, a zero-day exploit that uses an old version of the Server Block Message (SMB) protocol. The exploit is believed to have been discovered by the USA National Security Agency (NSA), and was later obtained by a hacker group called Shadow Brokers.
How do we protect ourselves from attacks like WannaCry?
According to this video, how do we protect ourselves from attacks like WannaCry? By using firewalls and password to encrypt all of our data, we can protect ourselves from attackers like Wannacry. You just studied 8 terms!

This particular type of malware lets hackers deny users access to the data on their computers by encrypting files. Once the files have been encrypted, the hacker can demand payment (i.e. a ransom) in exchange for the decryption key necessary to restore access to these files.
Why is SMB insecure?
For a certain kind of secure communication, Server Message Block (SMB) is no longer suited for the task. Windows machines use SMB to pass files around a network. SMBv1 is so insecure that most security experts now recommend that administrators disable it entirely via a group policy update.
How did the WannaCry ransomware exploit SMB vulnerability?

Are there any vulnerabilities in the SMB protocol?
Samba, an open source software that provides Windows file sharing access to non-Windows machine using SMB/CIFS protocol recently disclosed a similar remote code execution vulnerability to WannaCry that allows users authorized access via the SMB protocol. There is even a working exploit leveraging CVE-2017-7494 for Metasploit.
Are there any vulnerabilities similar to WannaCry or SambaCry?
Wanacry is one of the potential payloads when cve-2017-0144 is exploited. Other payloads have been dropped when cve-2017-0144 was exploited. In an unfortunate exploitation of marketing, the vulnerability CVE-2017-7494 was dubbed SambaCry. WannaCry is nothing at all like SambaCry.
How to check your network for ransomware attacks?
Go to the Network Topology Map and click “synchronize” – this will force the Unified Security Policy to recalculate. Now go to the dashboard and see the violations (you can also search for them in the Policy Browser). Additionally, customers can use Tufin’s REST APIs to automate the tasks above.
