Hello all,
I have recently enabled Suricata for my WAN connection. I noticed the following in my log:
2022-04-09T23:01:25-04:00 Warning suricata [100309] <Warning> -- [ERRCODE: SC_WARN_FLOWBIT(306)] - flowbit 'ETPRO.tefosteal.variant' is checked but not set. Checked in 2840863 and 0 other sigs
2022-04-09T23:01:25-04:00 Warning suricata [100309] <Warning> -- [ERRCODE: SC_WARN_FLOWBIT(306)] - flowbit 'ETPRO.maldocexe' is checked but not set. Checked in 2833022 and 0 other sigs

What do these mean and is it something I need to be concerned about?
Thanks,
Steve
