Due to its outdated technology, SMBv1 is highly insecure. It has many exploits/vulnerabilities and many of these allow remote control execution on the target machine. Although there were warnings from cyber security experts about the SMB 1 vulnerabilities, the infamous WannaCry ransomware attack made it very clear as the attack targeted vulnerabilities found in SMBv1.

    SMB 1 was created in 1984 to share files on DOS.

    CIFS (or Common Internet File System) was introduced in 1996 by Microsoft as Microsoft’s version of SMB in Windows 95.

    SMB 2 was released in 2006 as a part of Windows Vista and Windows Server 2008.

    SMB 2.1 was introduced in 2010 with Windows Server 2008 R2 and Windows 7.
