zt_bak_001 — Recovery Services Vault lacks immutability protection¶
Summary
Severity: High · Pillar: Data · Chain role: ENABLER
Description¶
Recovery Services Vaults without immutability enabled allow operators with Backup Contributor (or higher) privilege to delete or mutate recovery points. In a ransomware scenario the attacker's first move after privilege escalation is to destroy backups so the victim has no choice but to pay. Immutable vaults refuse recovery-point deletion for the retention period, eliminating this attack step.
