In the ever-evolving world of cybercrime, ransomware has continually adapted to exploit new vulnerabilities. What began as crude email-based extortion schemes has grown into sophisticated, multi-layered operations capable of paralyzing global enterprises. Now, the next frontier is emerging—targeting cloud backup systems, the very safety nets organizations rely upon to recover from attacks. According to VPNpro reviews, VPNpro experts have noted a concerning rise in cases where attackers infiltrate cloud environments to encrypt or delete backups, making recovery almost impossible without paying the ransom.
Cloud Storage: Once Safe, Now a Prime Target
For years, businesses and individuals considered cloud storage bundled with VPNs as an impenetrable shield against ransomware. The idea was simple: if local data were compromised, cloud backups could restore systems within hours via secure channel. But attackers have caught up. Modern ransomware campaigns no longer stop at encrypting files on physical machines—they now probe network connections and authentication systems to locate and compromise backup repositories.
What makes cloud backups appealing to hackers is their centralized nature. Once inside a cloud account, criminals can often access multiple systems and user accounts. This “single point of failure” makes cloud infrastructure a high-value target. As companies move to hybrid or fully remote work models, the risks multiply, since credentials are often shared across devices and networks.
The Rise of Double and Triple Extortion
Traditional ransomware merely encrypted files until victims paid for the decryption key. However, cybercriminals have evolved their tactics into double and triple extortion. In the double-extortion model, attackers first steal data and then threaten to leak it unless the ransom is paid. In the triple variant, they add another layer—attacking the organization’s customers, partners, or supply chain to escalate pressure.
Now, cloud backups fit perfectly into this dark strategy. By corrupting or wiping backups, attackers can ensure that victims have no recovery option. Even if the stolen data is leaked, the inability to restore critical systems makes payment almost unavoidable. The stakes have never been higher.
Misplaced Trust in Cloud Providers
Many organizations assume that major cloud providers automatically safeguard backups against ransomware. But while providers offer infrastructure security, data protection is still the user’s responsibility under the shared responsibility model. Misconfigurations, weak access controls, or insufficient encryption can open doors for attackers.
Furthermore, ransomware groups are now exploiting automation tools that sync data between local devices and the cloud. If ransomware encrypts a synced local folder, the infected files often propagate automatically to the cloud, replacing clean versions with encrypted ones. Without versioning or immutability settings, recovery becomes impossible.
The Way Forward
As ransomware evolves, defending cloud backups demands a shift from reactive to proactive security. Organizations must enforce immutable storage options, secure VPN tunneling, isolate backup networks, and implement strict identity management controls. Regular penetration testing and simulated ransomware recovery drills can reveal hidden weaknesses before attackers do.
The war against ransomware is no longer just about data encryption—it’s about survival in a digital ecosystem where the safety nets themselves are under siege. Cloud backups were once the solution; today, they are part of the battlefield.
