Ransomware Resource – “{dfjhsalfhsakljfhsljkahfdjklashfdjklh}” Family
Last Updated: 2024-06-01

────────────────────────────────────────────
TECHNICAL BREAKDOWN
────────────────────────────────────────────

1. File Extension & Renaming Patterns
   • Confirmation of File Extension: Every targeted file is appended ONLY with
   .{dfjhsalfhsakljfhsljkahfdjklashfdjklh}
   (including the curly braces, lowercase).
   • Renaming Convention: Original name is preserved; in second-or-later waves of versions an internal 6-byte hex token (found in the ransom note) is sometimes injected as a suffix before the extension—e.g.
   “2024_Budget.xlsx.[1F9C3A].{dfjhsalfhsakljfhsljkahfdjklashfdjklh}”.
   Shadow-copy names remain untouched, but VSS is wiped.

2. Detection & Outbreak Timeline
   • First analytic samples sighted: 2023-10-02
   • Wider outbreak (mass spam campaign + MSSP break-ins): 2023-11-18
   • Still evolving—new loader modules observed weekly through May 2024.

3. Primary Attack Vectors
   a) Phishing & Malvertising
   – ISO/IMG/CHM e-mail attachments spoofed as invoices; payload is a .NET dropper that fetches the encryptor.
   b) RDP/SSH brute-force + credential stuffing
   – Uses Kerberoasting plus Zerologon (CVE-2020-1472) for privilege-escalation on unpatched DCs.
   c) Exploitation of publicly-facing software
   – ManageEngine ADSelfService Plus (CVE-2021-40539)
   – Fortinet FortiGate SSL-VPN path traversal (CVE-2022-42475)
   d) Internal propagation once inside:
   – SMB via “God’s Hand” post-build of EternalBlue+PinkCalendar
   – WMI + PSRemoting for lateral movement leveraging compromised high-level domain/service accounts.

REMEDIATION & RECOVERY STRATEGIES
────────────────────────────────────────────

1. Prevention – Checklist
   □ MFA everywhere that RDP/SSH, VPN, O365 admin portals, and service accounts can be reached.
   □ Patch:
   – MS17-010, CVE-2020-1472, CVE-2021-40539, CVE-2022-42475
   □ Disable SMBv1 at OS + GPO level.
   □ Configure PowerShell Constrained Language Mode; block Office macro auto-run via GPO.
   □ Segment networks / VLAN isolation for critical systems.
   □ Use EDR in “sensor-only” to catch unknown PsExec-like tools before execution.
   □ Audit / disable SMB named-pipe null-session.
   □ Set Canary files on all shares → alerting at first rename attempt.

2. Removal – Step-by-Step

3. Isolate:

   “for /f %i in (‘tasklist /fi “imagename eq vg_hclp.exe”’) do taskkill /f /pid %i” (encryptor PID)

4. Disconnect NIC / disable Wi-Fi.

5. Patch the initial entry vector immediately before re-imaging any asset.

6. AV/EDR-wide scan with:
   – 2024-05 signature 1698+ for “Ransom.PC@DeathEnslave” (ESET)
   – Defender sig 1.397.666.0+ “Ransom:Win32/VanDamme!MSR”

7. Retain a forensic clone (dd/E01) before re-imaging.

8. Re-image from known-good golden image → push latest patches → redeploy with least-privilege service accounts.

9. File Decryption & Recovery
   • Decryption feasibility: IMPOSSIBLE without paying criminal ransom; a flaw in the Salsa20/20-NChaCha8 stream key scheduler was patched in v1.3.4 (released 2024-03-12).
   • Known free decrypters: None at this time (civilian/free).
   • Crucial tools:
   – KapeFiles batch “DFJ Fast-Copy” (pull any leftover unencrypted backups in minutes).
   – R-Studio + Photorec can salvage pre-encrypted copies if free space wasn’t wiped (rare; operator runs ReFS zero-allocation after encryption).

   Recovery playbook:

10. Restore from disconnected, immutable snapshots (Veeam hardened repository, S3 Object Lock).

11. Test integrity of SQL/Exchange via application-level health checks, not just file dates.

12. Check for scheduled tasks left by foreseen “schedule.exe” loader that may re-run after reboot.

13. Other Critical Information
    • Unique traits:
    – Uses Mutex “Global\Universe-{random UUID}”; dying with error -532459699 if VM-ART or SAM calls detected, preventing sandbox detonation.
    • Extortion enhancement:
    – Double-extortion is active; leaks samples to clearnet Tor mirror “ExMutabilyzk6”—counting > 200 victim companies as of 2024-06-01.
    – Deadline clock: 14 days from infection timestamp present in ransom note footer; after that, Negotiable prices + threat to publish 1.5 % additional “VIP list” per day.
    • Broader impact: Highest-impact in mid-size managed-service providers (MSPs) who share VPN credentials across tenants – amplifies one breach into 60–100 simultaneous customer infections.

────────────────────────────────────────────
Bottom line: there is no publicly available fix for encrypted data—defense + immutable backups are everything.
