Ransomware no longer means only encrypted files. A serious intrusion can control whether systems and network shares are usable, copy confidential information for extortion, seize administrator accounts and management tools, and destroy the backups needed for recovery. The practical question is therefore not simply “Were files encrypted?” but “Which parts of the organization’s control surface did the attackers reach?”
The four control layers of a modern ransomware attack
Federal guidance describes ransomware as malware that blocks access to files, systems or networks and demands payment. Current incidents show that the impact usually spans four connected layers: availability, confidentiality, identity and administration, and recoverability.

| Control layer | What attackers can affect | What the victim experiences |
|---|---|---|
| Availability | Local files, attached drives, network shares, endpoints, virtual machines and services | Users cannot open data or operate systems |
| Confidentiality | Copied documents, databases, credentials and other sensitive information | Threats to publish or sell the data, even after restoration |
| Identity and administration | Ordinary, service, privileged and domain accounts; remote-management tools | Attackers move laterally and change systems before encryption |
| Recoverability | Backup consoles, repositories, archives and disaster-recovery environments | Clean restore points are altered, disabled or deleted |
Availability: denying access to more than a laptop
The FBI says more advanced ransomware encrypts files and folders on local drives, attached drives and networked computers. The Play advisory describes this as “Data Encrypted for Impact,” interrupting access to system and network resources. If a compromised account can write to a shared folder, a mapped drive or a server volume, those locations may be encrypted even when the original infection began on one workstation.
That reach can include business applications, file servers, virtual machines and other network resources. Encryption is not always the only method: attackers may disable services, remove access, or alter configurations so that systems are unavailable while the extortion demand is made.

Confidentiality: theft can continue after systems are restored
NIST’s June 11, 2026 ransomware profile notes that attackers may steal an organization’s information and demand additional payment not to disclose it to authorities, competitors or the public. This “double extortion” separates two harms: restoring availability does not undo a disclosure risk.
The Gunra advisory describes actors that both exfiltrated and encrypted sensitive data, then threatened to publish it on a leak site if the victim did not pay within five to seven days. A CISA and FBI update on Medusa likewise reports encryption combined with threats to publish exfiltrated data. Those timelines and tactics describe the incidents in the advisories, not a universal rule for every ransomware case.
Identity and administration: the breach often expands before encryption
Attackers commonly seek control of accounts and tools first. The Play advisory documents use of valid accounts, exploitation of public-facing applications, external remote services such as RDP and VPN, credential dumping with Mimikatz, PowerShell, Group Policy distribution and lateral transfer of tools. Medusa reporting adds phishing, access brokers, unpatched internet-facing vulnerabilities, remote-monitoring software and RDP.

An administrator or domain account can let an intruder deploy code broadly, disable security controls, create persistence and reach servers that an ordinary user cannot. A service account may provide a different route into databases or backup systems. The account itself is therefore part of the attack surface, not merely a way to log in.
Recoverability: the backup path is a target
Recovery fails when the attacker controls the systems that hold or administer the backups. Gunra reporting describes disabled backup features and, in one incident, deletion of backup and archived data at both a primary data center and a disaster-recovery center. The FBI advises keeping backups regular, verified and disconnected from the computers and networks they protect. Joint CISA, FBI and Play guidance calls for offline, immutable backups in a physically separate, segmented location, covering the entire data infrastructure.
Keeping backup credentials and management paths separate from ordinary production credentials is a practical consequence of that isolation guidance. It reduces the chance that one stolen administrator session can erase both live data and its recovery copies.

What happens when ransomware reaches a network share?
A network share is available to any account with sufficient permissions. If ransomware runs under such an account, it can enumerate shares and encrypt files across them. The resulting outage may look like a server failure even though the initial foothold was a desktop, VPN session or exposed remote service.

- Shared folders can be encrypted in bulk when the infected identity has write access.
- Mapped drives and attached storage can be affected alongside local disks.
- Permissions may remain technically correct while the underlying files are unreadable.
- Segmentation and least-privilege access limit how far one compromised identity can reach.
Can attackers steal data without encrypting it?
Yes. Data theft and encryption are separate actions. An intrusion may exfiltrate documents, customer records or other sensitive material and use the threat of publication as leverage, even if the victim restores every system from a clean backup. Official advisories do not establish one current, cross-industry percentage for how often exfiltration occurs, so a generic rate would be misleading.
Incident response should therefore determine both what became unavailable and what may have left the environment. Preserving logs, identifying accessed repositories and reviewing outbound transfers are necessary even when no encryption note appears.

What if attackers obtain an administrator account?
Administrative access can turn a localized compromise into an organization-wide event. Attackers may use valid credentials to access remote services, push software through policy tools, dump additional credentials, disable defenses and search for backup consoles. The exact result depends on permissions, segmentation and monitoring, but the risk is substantially greater than compromise of a single standard user.
- Disable or isolate the suspected account and preserve evidence; do not simply delete logs or rebuild without an incident plan.
- Revoke active sessions, rotate credentials and inspect related service and domain accounts.
- Check remote-access, PowerShell, Group Policy and management-tool activity for lateral movement.
- Assume backup administration is exposed until its credentials and management paths are independently verified.
Can ransomware delete backups?
It can, if the attacker reaches the backup infrastructure or its administration. The Gunra cases specifically describe disabled backup functions and deletion of backup and archived data at primary and disaster-recovery locations.
A resilient design uses several barriers:
- Offline copies: disconnected from production except during controlled backup or restore operations.
- Immutability: retention controls prevent ordinary administrative sessions from altering or deleting versions.
- Physical separation: a second location limits a single-site compromise or outage.
- Encryption: protects backup contents if media or repositories are accessed.
- Restore testing: verifies that backups are complete and usable, rather than merely reporting a successful job.
An offline backup external hard drive or encrypted SSD/HDD can be one component of this process for a small environment. A consumer drive is not automatically immutable, does not provide enterprise retention or monitoring by itself, and must be disconnected or otherwise isolated from the systems it protects.

Does paying guarantee the files will return?
No. The FBI states: “The FBI does not support paying a ransom in response to a ransomware attack. Paying a ransom doesn’t guarantee you or your organization will get any data back.” Decryptors may fail, attackers may demand more money, and stolen data may still be published. Payment also does not repair compromised accounts or prove that the environment is clean.
Organizations should involve their incident-response and legal teams, follow applicable reporting requirements, and contact the FBI or CISA as appropriate. A payment decision cannot substitute for containment, evidence preservation and restoration from trusted copies.
How to reduce the control surface before an incident
- Patch internet-facing systems. Prioritize VPN gateways, RDP-exposed infrastructure and other public-facing applications; the Gunra and Medusa advisories identify these routes in observed attacks.
- Segment the network. Separate user devices, servers, management interfaces and backup environments so an initial compromise cannot freely reach every system.
- Protect identities. Minimize standing administrator rights, use separate backup-management credentials and monitor unusual use of remote services, PowerShell and policy tools.
- Build isolated backups. Maintain encrypted, offline or immutable copies in a physically separate or segmented location, with retention that attackers cannot change through production credentials.
- Test restoration. Perform scheduled recovery exercises for critical applications, shared data and whole-system dependencies; record how long each service takes to return.
- Prepare continuity and response plans. Define who can isolate systems, communicate with staff and regulators, preserve evidence and make recovery decisions before an emergency.
How to assess an incident’s real scope
Use five questions rather than treating the ransom note as the incident summary:
- Availability: Which files, endpoints, shares, virtual machines or services are unusable?
- Confidentiality: What data was accessed or copied, and who could receive it?
- Identity reach: Which ordinary, privileged, service or domain accounts were used?
- Recovery reach: Were backup repositories, archives or disaster-recovery systems accessed, altered or deleted?
- Operational resilience: Which segmentation, detection, continuity and restoration controls worked or failed?
That assessment produces a more accurate picture than asking only whether files were encrypted. Medusa actors, according to the August 18, 2026 CISA and FBI update, had impacted more than 500 victims as of April 2026 across sectors including healthcare, defense industrial base, critical manufacturing, government services and facilities, information technology and financial services. The figure illustrates the breadth of the threat, not a probability that applies to every organization.
