    Test A-R53-11 specifically looks for Domains that do not have a transfer lock enabled. A transfer lock is nothing more than an additional step ahead of transferring a domain to ensure a “belt & braces” type confirmation that a domain should definitely be transfered. All a transfer lock requires is that the transfer lock is disabled by an API call or a confirmation in the AWS Web Console ahead of initiating a transfer. However, this simple mechanism provides a few additional features to help protect domains from being stolen, even to insiders.

    Reference: When is S3 data public?

    SkySiege tests A-S3-4, A-S3-5, A-S3-6, A-S3-7, A-S3-8 and A-S3-9 all focus on public access blocks and the quality of S3 Bucket Policies. The reasoning for this is simple - Public Access Blocks and Bucket Policies are front line protections for ensuring that your data is not publicly available.

    Reference: Cracking Weak DKIM

    Test A-R53-10 reviews DKIM records to determine if the DKIM key is of a suitable size. As the DKIM key is part of a asymetric keypair we can infer certain properties of the corresponding private key, including the key size. Therefore using small key sizes for DKIM signatures publicly advertises that your private key must also be a small size and therefore subsceptible to cracking.

    The researchers at Jedi Security successfully cracked a 512-bit DKIM key and were able to forge an email with the cracked key which successfully passed DKIM checks across a number of top email service providers.

    Test A-R53-8 specifically looks for Domains that are due to expire within the next 90 days that do not have any form of auto renewal. We reference the risk for expired domains to get squatted whereby a third party captures the domain and utilises it for ransom, SEO capture or other nefarious schemes. However, there’s an additional level of risk in the data that the domain has implicit ownership over that has been proven by other researchers in the field.
