This is the best summary I could come up with:

Responding to Wyden’s letter last week, Microsoft brushed off the criticisms, saying: “This incident demonstrates the evolving challenges of cybersecurity in the face of sophisticated attacks.

It is for this reason that we are withholding all technical details.” While Yoran’s post and Tenable’s disclosure avoid the word vulnerability, the email said the term is accurate.

The post came on the same day that security firm Sygnia disclosed a set of what it called “vectors” that could be leveraged following a successful breach of an Azure AD Connect account.

“The default configuration exposes clients to the described vectors only if privileged access was gained to the AD Connect server,” Ilia Rabinovich, director of adversarial tactics at Sygnia, wrote in an email.

Both Tenable and Sygnia said that the security vulnerabilities or vectors they disclosed weren’t related to the recent attack on Microsoft cloud customers.
