New Ransomware Strain Targets Backup Software – Here’s Why Softyz Inc Users Are Protected

New Ransomware Strain Targets Backup Software – Here’s Why Softyz Inc Users Are Protected

A new ransomware variant identified this week specifically targets popular local backup tools by encrypting their cache files and connected drives before encrypting the rest of the system. Here’s a technical breakdown of how it works, the indicators of compromise, and why Softyz’s architecture makes this entire attack vector ineffective.

[threat-intel] new variant detected – backup-cache targeting behaviour
⚠ alert: process attempting to enumerate local backup directories
⚠  alert: connected drive scan detected – File History / Time Machine cache match
✓ Softyz Inc: cloud sync isolated – WORM lock active – 0 versions affected
softyz-agent: backup integrity check passed – 100% versions intact

This week, security researchers identified a new ransomware variant that introduces a notable evolution in tactics: before encrypting a victim’s general files, it specifically searches for and targets local backup software caches and connected backup drives first.

This is a meaningful escalation. Traditional ransomware encrypts files indiscriminately. This new approach deliberately prioritises destroying the victim’s ability to recover – by going after Time Machine caches, Windows File History snapshots, and externally connected drives matching common backup signatures, before moving on to documents and photos.

If you are a Softyz Inc user, you are already protected against this attack vector. This article explains exactly why – and what to check to confirm your protection is active.

About this advisory
This advisory is based on threat intelligence reports shared across the security community this week. Specific details may evolve as more analysis becomes available. The defensive guidance in this article – particularly using offsite immutable cloud backup – applies broadly regardless of how the variant evolves.
How this attack chain works

Based on reported behaviour patterns, the attack proceeds through these stages once a device is compromised – typically via a phishing attachment or a trojanised installer:

1

Initial access & reconnaissance

The malware gains a foothold and spends time scanning the file system – looking specifically for known backup software directories, drive letters, and process names associated with popular backup tools.

Softyz Inc defense: Scheduled time file monitoring can flag anomalous process and scanning activity to the user via email alert.
2

Backup cache and connected drive targeting

The malware locates local backup caches – Time Machine local snapshots, Windows File History storage, and any externally connected USB drives or NAS shares with recognisable backup folder structures – and encrypts these first.

Softyz Inc defense: Softyz Inc backups live in the cloud, not a local cache. There is no local “Softyz Inc folder” of backup data for malware to find and encrypt – your history exists only in immutable cloud storage.
3

Attempted cloud sync poisoning

For victims using cloud sync services, the malware encrypts local files within the sync folder – and the sync client dutifully uploads the encrypted versions, overwriting clean cloud copies within minutes.

Softyz Inc defense: WORM immutable storage means previously backed-up versions cannot be overwritten by any later upload, encrypted or not. Every prior version remains intact and restorable.
4

General file encryption & ransom note

With local backups destroyed and cloud sync copies poisoned, the malware encrypts the victim’s documents and photos, then displays a ransom note. Victims relying only on local or sync-based “backup” have no clean recovery option left.

Softyz Inc defense: Abnormal mass-encryption activity is detected within seconds via Scheduled time change-rate monitoring, isolating the backup connection. The clean restore point from immediately before the attack stays available.
Why Softyz’s architecture neutralises this attack vector

This variant is specifically engineered to defeat local backup strategies and sync-based “backup” – the two approaches most people unknowingly rely on. Softyz Inc was architected from day one around assumptions that directly counter both:

  • No local backup cache to find or encrypt – there is nothing on your device for the malware’s drive-scanning logic to locate.
  • WORM immutability prevents overwrite – even a “legitimate-looking” re-upload from a compromised device cannot replace existing clean versions.
  • Scheduled time anomaly detection isolates compromised devices automatically – a sudden mass-encryption event triggers isolation of that device’s backup connection within seconds.
  • Zero-knowledge encryption means your cloud copy is unreadable without your private key, which never leaves your device unencrypted.
“This variant is a reminder that ransomware groups study defensive tools and adapt. The response isn’t panic – it’s making sure your backup architecture doesn’t have the local attack surface this malware is designed to exploit.” – Priya Sundaram, CTO, Softyz Inc.
3 things to check right now
3-Minute Protection Verification
✓
Check your last backup timestamp. Open softyzinc.com and confirm each device shows a recent backup time – ideally within the last hour.
✓
Confirm Scheduled time backup is enabled. Settings → Backup → Frequency should be “Scheduled time” or “Continuous”, not a scheduled interval.
✓
Verify version history is active. Open any important file in the Web Manager and confirm Version History shows multiple saved versions over time.
General precautions beyond Softyz Inc
  • Don’t open unexpected attachments – even from known contacts. Verify via a separate channel if uncertain.
  • Download software only from official sources – trojanised installers are a common distribution method.
  • Keep your OS and antivirus updated – many variants exploit known, patchable vulnerabilities.
  • Enable 2FA on your Softyz Inc account – Account → Security → Two-Factor Authentication.
  • If you suspect infection, disconnect from the network immediately and follow our ransomware recovery guide.
✅ If your device is encrypted by this or any ransomware variant
  • Disconnect the device from your network immediately
  • Do NOT pay the ransom – your Softyz Inc cloud backup is unaffected
  • Access softyzinc.com from a different, clean device
  • Identify your last clean restore point (immediately before the attack)
  • Wipe the infected device and reinstall the OS
  • Reinstall Softyz Inc and restore your files from the clean version
  • Contact support@softyzinc.com for guided recovery and a post-incident audit

ℹ️ We will continue monitoring this threat
Softyz’s security team is actively monitoring threat intelligence related to this and similar variants. If new information requires additional guidance, we’ll update this advisory and notify affected users directly via email. No additional action is required from Softyz Inc users beyond the verification steps above.
