Microsoft Purges Dormant Azure Tenants, Rotates Keys to Prevent Repeat Nation-State Hack https://www.securityweek.com/microsoft-purges-dormant-azure-tenants-rotates-keys-to-prevent-repeat-nation-state-hack/

Microsoft security chief Charlie Bell says the SFI’s 28 objectives are “near completion” and that 11 others have made “significant progress.”

Microsoft, touting what it calls “the largest cybersecurity engineering project in history,” says it has moved every Microsoft Account and Entra ID token‑signing key into hardware security modules or Azure confidential VMs with automatic rotation, an overhaul meant to block the key‑theft tactic that fueled an embarrassing nation‑state breach at Redmond.

Just 18 months after rolling out a Secure Future Initiative in response to the hack and a scathing US government report that followed, Microsoft security chief Charlie Bell said five of the program’s 28 objectives are “near completion” and that 11 others have made “significant progress.”

In addition to the headline fix to put all Microsoft Account and Entra ID token‑signing keys in hardware security modules or Azure confidential virtual machines, Bell said more than 90 percent of Microsoft’s internal productivity accounts have moved to phishing‑resistant multi factor authentication and that 90 percent of first‑party identity tokens are validated through a newly hardened software‑development kit.

If someone asked me what was the best way to make money from a compromised AWS Account (assume root access even) — I would have answered “dump the data and hope that no-one notices you before you finish it up.”

This answer would have been valid until ~8 months ago when I stumbled upon a lesser known feature of AWS KMS which allows an attacker to do devastating ransomware attacks on a compromised AWS account.

Now I know that ransomware attacks using cross-account KMS keys is already known (checkout the article below)— but even then, the CMK is managed by AWS and they can just block the attackers access to the CMK and decrypt data for the victim because the key is OWNED by AWS and attacker is just given API access to it under AWS TOS. Also there’s no way to delete the CMK but only schedule the key deletion (min 7 days) which means there’s ample time for AWS to intervene.

A recent breach in MSI's servers exposed Intel's BootGuard keys and has now put the security of various devices at risk.

Major MSI Breach Affects The Security of Various Intel Devices
Last month, a hacker group by the name of Money Message revealed that they had breached MSI's servers and stolen 1.5 TBs of data from the company's servers including source code amongst a list of various files that are important to the integrity of the company. The group asked MSI to pay $4.0 million in ransom to avert them from releasing the files to the public but MSI refused the payment.
