Run ./aws_secret.sh

Refer to: https://github.com/redcanaryco/atomic-red-team/blob/master/atomics/T1098.001/bin/aws_secret.sh

I've generated aws_secret.creds following this command:

aws iam create-access-key --user-name #{username} > "$PathToAtomicsFolder/T1098.001/bin/aws_secret.creds"
cd "$PathToAtomicsFolder/T1098.001/bin/"
./aws_secret.sh
