For years, ransomware followed a predictable pattern. Attackers would break in, encrypt data, and demand payment. Backups were the safety net. If something went wrong, organizations could restore and move on.
That model is breaking down. Today’s ransomware groups are changing the sequence. Instead of encrypting first, they are going after backup systems before anything else. The goal is simple: remove the ability to recover, then launch the attack. This shift isn’t theoretical, It’s already visible in modern campaigns, especially those using tactics similar to LockBit-style operations, where attackers prioritize control over recovery systems before triggering disruption.
According to Sophos, nearly 94% of organizations hit by ransomware in recent reports said attackers attempted to compromise their backups, showing how central backup targeting has become in modern attacks.
When Ransomware Goes After Backups First
In many recent incidents, attackers don’t start with encryption. They start by quietly moving through the network, identifying backup environments, and taking them out of the picture. Only once recovery options are gone do they execute the ransomware.
This pattern has been seen repeatedly in attacks associated with groups using LockBit-style methods.
In one such case, a mid-sized manufacturing company experienced what initially looked like a standard breach. Access was gained through compromised credentials, and for several days, nothing unusual was detected. But behind the scenes, the attackers were mapping the environment. They located backup servers, accessed administrative controls, and deleted recent backup snapshots. Monitoring systems tied to backups were also disabled, ensuring no alerts were triggered. Everything appeared normal, until it wasn’t. When encryption finally began, operations were disrupted almost immediately. The IT team moved to restore systems, expecting backups to be available. Instead, they found that critical recovery data was missing or corrupted.
What should have been a short recovery turned into prolonged downtime.The real issue wasn’t just the ransomware, it was the cyber recovery failure.This is why ransomware backup targeting and backup system attacks are now defining modern threats. Once backups are compromised, organizations lose their strongest line of defense.
Research from Veeam shows that over 75% of organizations experienced at least partial backup compromise during ransomware incidents, directly impacting their ability to recover.
Why Backups Have Become the Weakest Link
Backups were never designed to be the front line of defense. They were built as a fallback. But attackers have caught up to that thinking.
Once inside a system, it’s often easier to reach backup environments than organizations expect. Shared credentials, weak access controls, and tightly connected infrastructure make it possible for attackers to move laterally without much resistance. And because backups are rarely monitored as closely as production systems, the damage can go unnoticed. By the time encryption begins, the real work has already been done.
Most recovery strategies assume that backups are intact and available. But when attackers delete or corrupt those backups first, that assumption collapses. This is where organizations run into real trouble.
Recovery timelines stretch. Data gaps appear. Operations slow down or stop entirely. What could have been a manageable disruption turns into a full-scale business impact.
According to the Cybersecurity and Infrastructure Security Agency, attackers increasingly target and disable backup systems early in the attack lifecycle, specifically to prevent recovery and increase pressure on victims.
This is the reality of cyber recovery failure, not just being attacked, but being unable to recover.
Why Immutable Storage Is Now Essential
To counter this, more organizations are turning to immutable storage.The idea is simple. Once data is written, it cannot be changed or deleted for a defined period. Even if attackers gain access, they can’t erase what’s already protected.
In the context of modern ransomware, this changes everything.It ensures that backups remain intact even when primary systems are compromised. It gives organizations a way to recover without relying on attackers. But immutability isn’t just a feature you switch on. It has to be part of a broader strategy, combined with proper access controls, isolation, and governance. Otherwise, it becomes just another layer that can be bypassed.
Many organizations assume their backups are working because jobs are running successfully. But successful backups don’t always mean recoverable data.Without regular testing, backups can be incomplete, outdated, or corrupted.
Attackers know this. They rely on the assumption that no one checks until it’s too late. Closing this gap means treating backups like critical systems, not background processes. They need visibility, monitoring, and regular testing to ensure they actually work when needed. This is where enterprise data resilience comes in.
Enterprise data resilience is no longer defined by how much data is backed up, but by how reliably that data can be recovered under attack. In modern ransomware scenarios, backups are not outside the attack surface, they are part of it. If they are not isolated, protected, and continuously validated, they can be compromised just as easily as production systems.
This shift is reinforced by findings from Palo Alto Networks Unit 42, which show that attackers often spend days or weeks inside networks specifically identifying and weakening recovery systems before launching ransomware. This shifts resilience from a storage problem to an operational one. The focus moves to whether recovery is still possible when attackers have already moved through the environment.
Where Open Storage Solutions Fits In
As ransomware continues to evolve, the focus is moving beyond prevention toward resilience and recovery. At Open Storage Solutions, we follow these shifts closely and share insights to help organizations stay prepared. As threats like ransomware backup targeting and backup system attacks become more common, storage can no longer be treated as passive infrastructure. We work with enterprises to strengthen how their storage environments handle security, access, and recovery under pressure. That includes supporting architectures where data remains protected, accessible, and reliable even when systems are under attack. The focus is not just on storing data, but on ensuring that when recovery is needed, it is actually possible.
