Storm-0501 wipes Azure data after ransomware attack

Victims were left unable to recover data after attackers erased cloud assets post-exfiltration.

Microsoft has introduced MAI-Voice-1 and MAI-1 Preview, its first in-house AI models designed for audio and text tasks.

A ransomware group has destroyed data and backups in a Microsoft Azure environment after exfiltrating sensitive information, which experts describe as a significant escalation in cloud-based attacks.

The threat actor, tracked as Storm-0501, gained complete control over a victim’s Azure domain by exploiting privileged accounts.

Microsoft researchers said the group used native Azure tools to copy data before systematically deleting resources to block recovery efforts.

After exfiltration, Storm-0501 used AzCopy to steal storage account contents and erase cloud assets. Immutable resources were encrypted instead.

The group later contacted the victim via Microsoft Teams using a compromised account to issue ransom demands.
