Ransomware Data Recovery Services

We combine proven engineering with ethical, repeatable methods to restore access to business-critical files and systems.

Restoring access starts with focused analysis of storage structures and file footprints.

Data carving inspects file headers, allocation tables, and block signatures across SAN/LUN, ZFS, and NetApp WAFL. When direct decryption is unsafe or impossible, carving reconstructs encrypted files and critical content without relying on attacker keys.

Safe decryption is used only when vendor or public decryptors expose real vulnerabilities or when proprietary tools verify key handling flaws. We validate any decryption in a controlled lab to prevent corruption and prove recoverability.

Backup and tape restoration covers LTO, DLT, Veeam, Commvault, and Acronis media—even when catalogs were wiped. Our team repairs VBK/VIB files, maps VM dependencies, and brings virtual machines online to restore business services quickly.

Ethics and mediation: we do not buy keys or advise you to pay ransom. Mediation is a last resort and is handled strategically to lower risk, cost, and operational harm while preserving legal and forensic integrity.

How do JIT custom-built tools help when standard utilities fail?

When off-the-shelf utilities can’t touch niche storage or legacy systems, Ontrack engineers build just-in-time tooling tailored to the environment.

These tools parse nonstandard file systems, extract intact files around encryption, and automate steps that would otherwise take days. That accelerates time-to-recovery and lowers manual error.

How do AI/ML and threat feeds speed containment?

Cohesity-driven AI/ML flags anomalous patterns and early malware behavior so teams act before wide spread. Curated threat intelligence maps known indicators of compromise and suggests safe decryptors or validated paths.

Automated SOC integrations push indicators across scans and orchestrations, making validation fast and repeatable.

What safeguards preserve restore integrity?

Zero Trust controls — MFA, role-based access control, and quorum approval — prevent unauthorized changes to backups. Immutable snapshots and WORM-like protections preserve clean restore points even under elevated attack.

Encryption scanning and classification separate suspect files from clean sets so restores avoid reinfection.

Capability Purpose Benefit
JIT custom tools (Ontrack) Handle legacy/niche systems Faster, accurate restores; fewer manual steps
AI/ML anomaly detection (Cohesity) Early detection of unusual patterns Prioritized containment and focused forensics
Immutable snapshots & cyber vaulting Protect backup integrity Guaranteed clean restore points; resists deletion
Zero Trust (MFA, RBAC, quorum) Prevent unauthorized changes Stronger security posture during incident

“Combining human expertise with intelligent tooling gives faster, more reliable outcomes than either alone.”
