When Backups
Become the Target

Why protected copies and a usable recovery path both matter when ransomware targets restoration.

The vulnerability of the intended escape route

“We have backups” is reassuring during a ransomware incident because it gives your organisation a way to restore affected data and systems. That reassurance rests on an important condition: the copies, the means of accessing them and the environment into which they will be restored must still be usable.

An attacker can target that condition. They may try to delete accessible copies, interfere with backup jobs or compromise the accounts and consoles used for restoration. Production systems could be encrypted only after the intruder has attempted to weaken the route your recovery team expects to use.

The question for your executive and infrastructure teams is therefore whether recovery can proceed if the attacker has deliberately targeted the recovery arrangements themselves.

A backup copy and a working route to recovery are related, but separate.
The copy may survive while the accounts, tools or infrastructure needed to use it are unavailable or compromised.

Why backups provide understandable reassurance

Backups give your organisation options after equipment failure, accidental deletion, corruption or malicious encryption. They remain an essential part of responsible operations and can reduce dependence on an attacker’s decryption offer.

Restoring after a deliberate intrusion introduces a different condition from replacing a failed server. The person causing the damage may also be seeking access to the copies and systems intended to repair it. Your recovery plan has to account for an adversary trying to obstruct the plan.

Consider a repository whose data remains intact while the backup management server is disabled and the recovery administrator’s account is compromised. There is still a valuable copy, but additional work is needed to establish authorised access and a suitable restoration environment. The distinction is operational: protecting the copy preserves an option; exercising the whole recovery route establishes how that option can be used.

The recovery path can be targeted before encryption

An intruder with access to your environment may investigate which accounts administer backups, where repositories are held, how snapshots are managed and which consoles control storage or virtual infrastructure. Those findings can identify opportunities to obstruct restoration before a visible outage begins.

Depending on the access obtained and the protections in place, an attacker may be able to delete unprotected snapshots, stop future backup jobs, change retention settings or damage the systems used to administer recovery. These are possible mechanisms, rather than a fixed sequence followed by every ransomware group.

Targeting does not make every copy unprotected

Veeam research - The 2024 Ransomware Trends Report
Repositories were targeted
The 2024 Ransomware Trends Report records backup-repository targeting in 96% of the attacks covered by its research. Its survey included 1,200 IT leaders and implementers from organisations that had experienced a cyberattack.

Veeam documentation - Backup Job has Too Many Restore Points - Considerations and Causes
A retention change is not an unlock
KB1990 distinguishes job retention from an immutable period. Protected files remain undeletable during that period even when the job’s retention setting would otherwise remove them.

Veeam help center - Hardened Repository
Separate protection has a purpose
Veeam describes immutable files and single-use deployment credentials that are not stored in the backup infrastructure. The design addresses a compromise of the backup server as a specific threat.

What these public records mean for your organisation
Review what a compromised administrator could actually change. Attempts to target backups justify examining access and protection; they do not establish that a properly enforced lock will be bypassed.

Note: Targeting is not successful deletion, total recovery loss or proof of pre-encryption timing. Product documentation describes a particular supported design, rather than protection against every possible compromise.

For your organisation, the relevant question is which of those actions a compromised account could perform. A general assurance that “the backups are separate” needs to be connected to actual administrative permissions, storage protections and the systems required to recover.

Protect the route as well as the copies

Recovery depends on more than the repository. Your team may need a management console, access credentials, encryption keys, network connections, available compute capacity and a defined order in which essential services can be rebuilt.

A weakness in one of those dependencies can delay restoration even when backup data survives. Shared administrative access can give an intruder a route from production into recovery systems. Loss of a console or key can prevent a team from using copies that remain physically intact. Insufficient alternative infrastructure can constrain where services are restored.

Your backup and incident teams should be able to explain which dependencies are independent of the affected production environment and which would have to be reconstructed. That is the practical meaning of protecting a recovery path: preserving the data and the ability to use it when ordinary administration is disrupted.

A cybersecurity infographic on a light background titled The Anatomy of a Secure Recovery Path, illustrating backup protection for CISOs. The left side maps a compromised route where a shared infrastructure console allows amber and purple threat energy to block access to physically intact immutable backup copies. The right side maps a defensible route where a titanium barrier and sapphire-glass containment layer isolate management credentials, encryption keys, and compute capacity, ensuring an executable recovery path.

What immutability protects

Immutability can prevent a protected backup file or object from being altered or deleted for a defined period. Correctly implemented protection can withstand attempts made through compromised backup-management credentials. An accepted administrator login does not automatically remove an enforced retention lock.

The protection depends on the storage design, configuration and the copies to which it applies. Veeam’s documentation, for example, distinguishes a backup job’s retention setting from an immutable period during which protected files cannot be deleted. The important question is which copies retain that protection, and for how long.

An immutable copy still needs a usable restoration route. The control does not, by itself, establish that all required data was included, that the chosen restore point predates compromise or that the accounts and target systems used for recovery are safe to use.

Offline copies, separation of administrative access and tested restoration arrangements add protection in different ways. Their combined value should be demonstrated against the recovery conditions your organisation may face.

Restoration cannot reverse data theft

If an attacker has copied sensitive information outside your organisation, restoring systems does not withdraw the information from the attacker. Availability can improve while the consequences of disclosure continue.

Your incident team still needs to investigate what was taken, while legal and communications teams assess the applicable notification requirements and the information that affected people or organisations need. Extortion over stolen data may continue even if operational recovery is successful.

The distinction matters when reporting progress. “The service has been restored” describes an operational result. It does not establish that the information was never accessed or that copies held outside your organisation have been destroyed. Data exposure needs its own investigation and response.

A restore point can contain an earlier compromise

An intruder with access to your environment may investigate which accounts administer backups, where repositories are held, how snapshots are managed and which consoles control storage or virtual infrastructure. Those findings can identify opportunities to obstruct restoration before a visible outage begins.

Depending on the access obtained and the protections in place, an attacker may be able to delete unprotected snapshots, stop future backup jobs, change retention settings or damage the systems used to administer recovery. These are possible mechanisms, rather than a fixed sequence followed by every ransomware group.

Recovery requires protected data and a usable route

Cybersecurity & infrastructure Security Agency - #StopRansomware Guide
Test the copies and protect clean systems
The #StopRansomware Guide recommends offline, encrypted backups and regular tests of availability and integrity. Its response guidance addresses the risk of reinfecting clean systems during recovery.
https://www.cisa.gov/stopransomware/ransomware-guide

National Institute of Standards and Technology - NIST Releases Tips and Tactics for Dealing With Ransomware
Prepare the restoration work and its owners
NIST recommends a planned and tested backup and restoration strategy, isolated backups, defined recovery roles and decision-making arrangements. Recovery preparation therefore includes the people and dependencies needed to use the copies.
https://www.nist.gov/news-events/news/2021/05/nist-releases-tips-and-tactics-dealing-ransomware

What these public records mean for your organisation
Apply the guidance to a practical scenario: the copy survives, but the usual management console or administrator account is unavailable. An exercise should show how the team establishes alternative access, selects a suitable restore point and restores an essential service.

Note: The scenario is illustrative, not a reported incident. Guidance describes precautions; it does not prove that every backup is contaminated or that a particular organisation can recover within its target time.

What your recovery team needs to demonstrate

A meaningful recovery exercise follows an essential service far enough to show that its data, accounts, infrastructure and operating dependencies can be brought together. The result should identify the conditions under which recovery succeeded and any dependencies that remained unresolved.

For your executive team, five questions make that evidence useful:

  • Which copies remain protected if a production or backup-management account is compromised, and which changes could that account still make?
  • Can the recovery team reach and use those copies if its usual console, identity service or production environment is unavailable?
  • What evidence supports the choice of restore point and the decision to reconnect the restored systems?
  • Which essential service has been restored in an exercise, with its dependencies, and how long did that take?
  • If information has already been stolen, which separate investigation and communication responsibilities remain after restoration?

How our platform supports a narrower incident

Our contribution is containment of specific harmful activity alongside your backup, identity, investigation and recovery arrangements. Ransomware Containment is our platform. It agentlessly monitors file activity in the protected data environment and isolates the responsible user, session or device when illegitimate encryption begins.

Additional Server Intrusion Protection (SIP) and Virtual Server Protection (VSP) features run on our platform. SIP detects and contains compromised server access, while VSP protects supported hypervisor environments against attacks directed at that layer.

Containing encryption, compromised server access or attacks against supported virtual infrastructure can help limit the extent of damage your recovery team has to address. Backup immutability, usable restore points, recoverable management systems and safe reconnection still require their own protection and validation.

See the effect of containing active encryption

Our remote ransomware resilience assessment demonstrates one defined capability. In an agreed, isolated test environment, we run controlled file-encryption scenarios with your existing security controls active, first without Ransomware Containment enabled and then with it enabled.

The comparison shows how active encryption is handled within the agreed test scope. It does not test backup survivability or restoration, clean restore points, SIP, VSP, lateral-movement interruption, data-exfiltration prevention, decision authority or wider business continuity. During the session, we definitively explain the additional features and discuss broader requirements separately. Request a ransomware resilience assessment
