Some versions of temporal ships with "/etc/services" and "/etc/protocols" files intact, which produced a number of false positives.
The "lockedFiles" rule was intended to catch ransomware, but it was found to match some lock file implementations. In temporal's case, it was due to https://gitlab.com/cznic/libc/-/blob/master/libc_musl.go#L561 - which is a dep of the sqlite implementation temporal uses.
