Anatomy of a credit card rewards program
Summary: In this article, the author discusses the intricacies of credit card rewards programs and how they are designed to attract and retain customers. The rewards programs are often based on interchange fees, which are paid by card-accepting businesses and incentivize card issuers to attract high-spending customers. Card issuers compete for "share of wallet" by offering various rewards, such as cashback or points for specific categories. The complexity of rewards programs has evolved over time, with some cards offering rotating categories or customizable rewards options.

Kobold letters: Why HTML emails are a risk to your organization
Summary: HTML emails can pose a security risk due to "kobold letters," elements that appear or disappear depending on the context in which the email is viewed. Attackers can exploit this feature to create phishing emails that appear legitimate when forwarded by a trusted sender. This issue affects most email clients and webmailers that support HTML email, including Thunderbird, Outlook, and Gmail. Users can mitigate the risk by disabling HTML email or viewing it in a restricted mode.
