With SQL and SAP HANA, the backup extension gets temporary access to write to specific blobs. ![]() With virtual machine backup, the backup snapshot creation and storage is done by Azure fabric where the guest or attacker has no involvement other than quiescing the workload for application consistent backups. The backup data is stored in Azure storage and the guest or attacker has no direct access to backup storage or its contents. SQL Server databases running on Azure VMs.On-premises files, folders, and system state.Azure BackupĪzure Backup provides security to your backup environment, both when your data is in transit and at rest. Since ransomware attackers have invested heavily into neutralizing backup applications and operating system features like volume shadow copy, it is critical to have backups that are inaccessible to a malicious attacker. One of the most important steps you can take to protect your data and avoid paying a ransom is to have a reliable backup and restore plan for your business-critical information. You should assume that at some point in time you will fall victim to a ransomware attack. For a comprehensive view of ransomware and extortion and how to protect your organization, use the information in the Human-Operated Ransomware Mitigation Project Plan PowerPoint presentation. Microsoft has invested in native security capabilities that make Microsoft Azure resilient against ransomware attacks and helps organizations defeat ransomware attack techniques. You can reduce your on-premises exposure by moving your organization to a cloud service. The best way to prevent falling victim to ransomware is to implement preventive measures and have tools that protect your organization from every step that attackers take to infiltrate your systems. Compromised customer trust or tarnished reputation.Depending on the scope of the attack, the impact could include: The impact of a ransomware attack on any organization is difficult to quantify accurately. Unlike early forms of ransomware that only required malware remediation, human-operated ransomware can continue to threaten your business operations after the initial encounter. These attacks can be catastrophic to business operations and difficult to clean up, requiring complete adversary eviction to protect against future attacks. The real damage is often done when the attack exfiltrates files while leaving backdoors in the network for future malicious activity-and these risks persist whether or not the ransom is paid. Once all of your data is encrypted and recent backups are also of encrypted data, your key is removed so you can no longer read your data. Your backups, though, are of the encrypted data. With your key still available, your data is usable to you and the ransomware goes unnoticed. Ransomware can also slowly encrypt your data while keeping your key on the system. Ransomware can be staged to exfiltrate your data first, over several weeks or months, before the ransomware actually executes on a specific date. The ransomware leverages the attackers’ knowledge of common system and security misconfigurations and vulnerabilities to infiltrate the organization, navigate the enterprise network, and adapt to the environment and its weaknesses as they go. While early ransomware mostly used malware that spread with phishing or between devices, human-operated ransomware has emerged where a gang of active attackers, driven by human attack operators, target all systems in an organization (rather than a single device or set of devices). Attackers use ransomware to extort money from victims by demanding money, usually in the form of cryptocurrencies, in exchange for a decryption key or in exchange for not releasing sensitive data to the dark web or the public internet. Ransomware is a type of extortion attack that encrypts files and folders, preventing access to important data and systems. Preparing for ransomware also improves resilience to natural disasters and rapid attacks like WannaCry & (Not)Petya.
