Possible unsigned DLL files?

[GregPlowman]

Within out corporate environment (Windows) we have received alerts from anti-malware software (Cortex) regarding suspicious DLL files.

libodbccr-2.dll
libboost_system.dll
libboost_date_time.dll

The report indicates these files are not signed, which contributed to their detection as potential security concerns.

My questions are:

• Are the DLL files indeed unsigned?
• If so, is this intended?

libodbccr-2.dll is used in unixODBC_jll
ODBC -> unixODBC_jll

libboost_system.dll and libboost_date_time.dll are used in boost_jll
SCIP -> SCIP_jll -> boost_jll
SCIP -> SCIP_PaPILO_jll -> boost_jll
