You may have heard of Server Message Block (SMB) version one. It’s a Windows protocol that has become a target for hackers, transmitting viruses quickly around company systems & networks. For this reason, Microsoft have removed the ability to deploy it from their new installations and strongly recommend upgrading to SMBv2, which does not contain the vulnerability.

SMB is a mechanism that enables users to map their network drive to a file share on the IBM i. As such, those IBM i systems interacting with SMBv1 contain a security risk. This effects the IFS & QDLS. It effects shared drives used for spread sheet input/output and BACS integration for example. If your systems are running iOS V7R2 or earlier they will be at risk as they only support SMBv1.

This fact sheet provides more information about this issue, as well as what to look out for.
