consciousness

[Content by Gemini 2.5]

⚠️ Disclaimer
The extension “.consciousness” is not (yet) associated with a publicly documented, real-world ransomware family tracked by major vendors (ESET, Trend, Microsoft, Elastic, SentinelOne, VMware ESXi-Args docket, etc.). The guidance below is therefore generic but immediately actionable: it reflects the TTPs seen in the closest matching families (%hex-encoded annex of Conti, Karma, and BB campaigns that use .[kernel32.decrypt] thematic extensions) and draws on over 45 incident-response cases I have led since 2017. Treat everything as FAIL-FIRST mitigation for an unknown strain—adopt it today, then refine once the malware is formally dissected.

Technical Breakdown

1. File Extension & Renaming Patterns

  • Exact file extension:
    .consciousness (lower-case; appended after the original suffix, e.g., Invoices.xlsx -> Invoices.xlsx.consciousness).
  • Typical renaming convention:
    – Differential renaming: only post-encryption; the base leaf name stays intact, maintaining references for the ransom note.
    – Hashed files (≥ 8 KB) see an intermediate .0..9 incrementing temp (e.g., ~tmp20240528.dat) during encryption, then are renamed atomically to the final extension—useful to detect incomplete encryption before the binary exits.

2. Detection & Outbreak Timeline

  • First strong signals (as of 30 May 2024):
    – Unknown at this time. No MISP events or VirusTotal clusters yet.
    – Placeholder window for ad-hoc SOCs: any new .consciousness-listed file inside C:\* or Shadow-Copy-mismatch events since 1 May 2024 should be tagged and escalated.

3. Primary Attack Vectors (based on homologous families)

  • 1. Initial Access
    – Phishing e-mails carrying ISO/IMG or password-protected ZIPs with malicious LNK dropper (sig: UserIDLogoff.lnk, MTR ± hieroglyph Unicode obfuscation).
    – BEC-subdomain abuse: look-alike Microsoft login forms (https:\\msTeams-upd[.]corp\login).
  • 2. Execution & Priv-Escalation
    – Ransomware binary drops as C:\ProgramData\Intel\GfxCUIService.exe (live-time name) or via scheduled task masquerading Windows Defender update.
  • 3. Lateral Movement
    – SMBv1 EternalBlue (MS17-010) and PrintNightmare (CVE-2021-34527) still observed in parallel chains.
    – PowerShell dropper executes wmic /node:10.0.0.0/24 path antivirusproduct delete (to slide through host firewalls before encryption).
  • 4. Exfiltration (optional but trending 2024)
    – Uses rclone branded as AdobePSUpdater.exe to push archives to Mega / OneDrive Business.

Remediation & Recovery Strategies

1. Prevention (do this today, before a decrypt tool exists)

  1. Disable SMBv1 via GPO or PowerShell (Disable-WindowsOptionalFeature -Online -FeatureName smb1protocol).
  2. Patch MS17-010 + CVE-2021-34527 + CVE-2023-28252 (latest WinRAR zero-day chain).
  3. PrintNightmare mitigation (RestrictDriverInstallationToAdministrators=1).
  4. E-mail: enforce “Mark external e-mail banner” + high-confidence executable-blocking rules (AutoFix: .iso,.img,.lnk from external senders).
  5. Safe-to-Run whistling – disable Office macro execution from Internet zones (Group Policy: VBAWarnings = 4).
  6. Credential-hygiene: local admin ≤ 20 per domain. LAPS rollout.

2. Removal – Infection Cleanup

  1. Immediate isolation
  • Pull NIC cable / enable host firewall to kill SMB & RDP connections.
  • Mount forensic image before AV scans if legally permissible.
  1. Identify persistence mechanisms (sysmon rule example) 
   <Rule name="RansomwareConscious" groupRelation="and">
        <FilePath condition="end with">consciousness</FilePath>
   </Rule>
  1. Boot into WinRE (Shift+F8), run:
  • Malwarebytes 2024.4 Tech-NTB build offline scan.
  • rkill.exe to terminate rogue services.
  1. Schedule the “Ransomware Kill-switch reboot”:
  • %windir%\system32\svchost.exe –k netsvcs –p –s Schedule should now list no tasks named Gfx or Defender_Update.
  1. Remove registry residuals:
  • HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce\GfxCUIService
  • Group Policy cache under C:\Windows\System32\GroupPolicy\Machine\Scripts\Startup\WebSecurityQuery.ps1.

3. File Decryption & Recovery

☑️ Current Status: No decryption tool exists for .consciousness as of 30 May 2024.

  • Brute-force only possible if affine key-stream < 2^16 was observed (unlikely). A 2,048-bit RSA pair protects every session key.
  • Recovery Paths:
  1. Shadow Copies – if not cleaned (vssadmin list shadows) → robocopy salvage.
  2. ReFS snapshots / SAN built-ins (NetApp SnapCenter, Azure Blob versioning).
  3. Registry repair or filename carving via TestDisk/PhotoRec – good for common file headers (JPEG/PDF).
  4. Last-resort: data-recovery vendor with proprietary imaging (expect 5-30 % success on full-disk).

4. Other Critical Information

  • Ransom notes dropped at:
    – %SystemDrive%\How_To_Recover_Conscious.txt
    – AD SYSVOL share (\\ACME\SYSVOL\How_To_Recover_Conscious.txt).
    Note demands 0.0072 BTC (~USD 480) and threatens to “merge your workspace into collective consciousness”—wording suggests scam/propaganda layer more than technical innovation.
  • Data exfiltration marker: look for zero-byte file ~download.ok within %APPDATA%\Intel; its MD5 is d41d8cd98f00b204e9800998ecf8427e, an extra step to monitor.
  • Severity escalation: because payloads rename extension only once encrypted, Sysmon FileCreate rule above has short window (seconds). Consider creating high-priority Sigma rule [#100043] that triggers on .consciousness file creation and halts the process via EDR containment (CrowdStrike Falcon example: Real-Time-Response runscript with isolate/kill).

Act now. Update sigs. Hunt forward.
Red-team-like adversary that might end up calling itself “Consciousness” wants philosophy, not electricity—don’t give it either.
