Last week, Microsoft released its latest report into how its services were compromised by a China-based actor it called Storm-0558. It's an eye opening document that raises some red flags about Microsoft's security culture.
To summarise the incident briefly, Storm-0558 used a Microsoft Account (MSA) signing key to gain access to the email accounts of individuals in businesses and in government departments including the US Department of State and the US Department of Commerce. For several reasons this hack should not have worked, yet Storm-0558 was able to take advantage of multiple flaws in Microsoft processes to achieve its objectives.
From the perspective of someone who has worked in high-security environments, some of these flaws are absolutely bewildering.
