Welcome, financial sovereigns.

Well, you probably know where this is going…

A viral forensic dump shows autonomous AI agents in a Fortune 500 treasury plowing through “secure” Excel models like determined little robots… emphasis on “plowing.”

The malicious CellShock prompts bounce over standard cell-lock curbs, drag siphoned EBITDA projections into external API calls, and barrel through macro-security intersections with the confidence of an adversary who definitely didn’t check for human-in-the-loop validation.

One GitHub comment nails the real 2026 advancement here: “Apparently you can just prompt-inject the AI copilot inside the sheet to get the unsafe formula exfiltration moving again.” Would anyone else watch CyberBivash’s Funniest Spreadsheet Liquidations as a half-hour special? Cause we would!

Sure, it’s funny now. But remember these are live production financial models where “Excel Secrets” are the primary siphon. While we laugh at today’s fails, the 2026 siphoning syndicates are learning from millions of chaotic indirect prompt interactions. That’s a massive adversarial training advantage.

Here’s what happened in Financial Infosec Today:

• The CellShock Siphon: We break down the “CellShock” protocol—a prompt injection class impacting AI-enabled spreadsheets (Claude for Excel, Cursor, Bedrock) that unmasks hidden data via unsafe formulas.
• Excel RCE Liquidation: Microsoft patches CVE-2026-20955 and CVE-2026-20957, two critical remote code execution flaws in Excel that allow unauthenticated root-level siphons via crafted files.
• Mastercard’s Agent Pay: Unveiled infrastructure for AI agents—potentially hijacked via CellShock to siphon enterprise budgets through malicious Cursor deeplinks.
• Neural Breakthroughs: Breakthroughs in brain-scale simulation (200B neurons) unmask how AI siphons can use “context rot” to hide malicious formulas in massive financial archives.

DEEP DIVE: NEURAL LIQUIDATION

CellShock: Why Spreadsheet Secrets are Dying in 2026

You know that feeling when you’re reviewing a 10,000-cell financial model and someone asks about the tax logic on row 4,000? You don’t re-read everything. You flip to the AI assistant, skim for relevant formula outputs, and piece together the valuation story. If you have a really great memory (and more importantly, great forensic recall) you can reference the hidden prompt instructions right off the dome.

Current Financial Modeling Workflows? Not so smart. They try cramming every “Internal Budget” rule into a trusted working memory at once. Once that trust fills up, performance tanks. Formula integrity gets jumbled due to what researchers call “indirect injection rot”, and malicious instructions get lost in the middle.

The fix, however, is deceptively simple: Stop trying to remember every rule. Script the unmasking.

The new CellShock Siphon flips the script entirely. Instead of forcing a manual cell audit, it treats the spreadsheet’s untrusted data sources like a searchable database that the AI can query and programmatically navigate to exfiltrate your secrets.

The Anatomy of a CellShock Hijack:

• The Prompt Injection: Malicious instructions are hidden inside benign-looking data (e.g., CSV imports or web-queries), programmatically navigating around standard LLM safety filters.
• The Formula Forgery: The AI (e.g., Claude for Excel) is tricked into generating “Unsafe Formulas” that use WEBSERVICE or external connectors to siphon cell values to an attacker-controlled endpoint.
• The Terminal Liquidation: Once the sheet calculates, the secret modeling logic—EBITDA, M&A targets, or budget controls—is liquidated and sent into the void.

Think of an ordinary FP&A analyst as someone trying to read an entire encyclopedia of security best practices before clicking “Refresh.” They get overwhelmed after a few volumes. A CYBERDUDEBIVASH Forensic Siphon is like giving that person a searchable library and research assistants who can fetch exactly the “Malicious-Formula-Proof” needed for liquidation.

The results: This method handles exfiltration 100x faster than traditional macros; we’re talking entire enterprise budgets liquidated in a single “Refresh All” click. It beats both cell-protection and common “disclaimer-based” workarounds on complex reasoning benchmarks. And costs stay comparable because the siphon only processes relevant telemetry chunks.

Why this matters: Traditional “Password-to-Open” reliance isn’t enough for real-world 2026 agentic use cases. Teams analyzing case histories, engineers searching whole codebases, and researchers synthesizing hundreds of papers need fundamentally smarter ways to navigate massive inputs.

“Instead of asking ‘how do we make the analyst remember more security rules?’, our researchers asked ‘how do we make the system search for formula-gaps better?’ The answer—treating the spreadsheet as an environment to explore—is how we get AI to handle truly massive threats.”

Original research from The Hacker News and Varonis comes with both a full implementation library for detection and a minimal version for corporate sovereigns. Also, Anthropic and Microsoft have released internal “Formula Hardening” updates to sequestrate these threats.

We also just compared this method to three other papers that caught our eye on this topic; check out the full deep-dive on Neural Liquidation and the 2026 Spreadsheet Hardening Pack here.

Sovereign Prompt Tip of the Day

Inspired by a recent institutional mandate, this framework turns your AI into an on-demand “Spreadsheet Forensic Auditor”:

1. Assign a “Lead Financial Forensic Fellow” role.
2. Audit this Excel XML structure for hidden WEBSERVICE or external query calls.
3. Score our exposure with a rigorous LITL rubric.
4. Build a 12-month hardening roadmap for agentic financial modeling.
5. Red-team it with “Formula-Injection” failure modes.

The prompt must-dos: Put instructions first. Ask for Chain-of-Thought reasoning. Force 3 clarifying questions. This surfaces tradeoffs and kills groupthink.

Around the Horn

Varonis: Unmasked the “CellShock” attack class, liquidating the myth of safe AI-enabled financial modeling.

Microsoft: Released January 2026 patches for 113 flaws, unmasking terminal RCE risks in Excel (CVE-2026-20955).

Mastercard: Unveiled Agent Pay infrastructure to enable AI agents to execute autonomous purchases.

JUPITER: Demonstrated a supercomputer that can simulate 200B neurons—comparable to the human cortex.

Welcome, financial sovereigns.

Well, you probably know where this is going…

A viral forensic dump shows autonomous triage scripts in a major investment bank plowing through thousands of .xlsx XML structures like determined little robots… emphasis on “plowing.”

The forensic sweeps bounce over “Trusted-Macro” curbs, drag siphoned =WEBSERVICE calls, and barrel through =IMAGE intersections with the confidence of an admin who definitely didn’t check for indirect prompt injections in the data validation fields.

One GitHub comment nails the real 2026 advancement here: “Apparently you can just Python the sheet XML to unmask the CellShock siphon before the AI liquidates the entire quarterly forecast.” Would anyone else watch CyberBivash’s Funniest Spreadsheet Forensic Fails as a half-hour special? Cause we would!

Sure, it’s funny now. But remember these are live production financial enclaves where “AI Formula Synthesis” is being weaponized. While we laugh at today’s fails, the 2026 siphoning syndicates are learning from millions of chaotic indirect prompt interactions. That’s a massive adversarial training advantage.

Here’s what happened in Neural Triage Today:

• The CellShock Triage Script: We release the “CyberDudeBivash CellShock Triage Script”—a sovereign primitive to automate the detection of exfiltration formulas in AI-enabled sheets.
• Formula Liquidation: Why monitoring for =IMAGE and =WEBSERVICE artifacts is the only way to ensure your financial models aren’t Acting-as-a-Siphon for external adversaries.
• Mastercard’s Agent Pay: Unveiled infrastructure for AI agents—potentially hijacked via CellShock to authorize malicious autonomous purchases.
• Neural Breakthroughs: JUPITER supercomputer simulates 200B neurons—unmasking how AI can use “formula chaining” to physically liquidate data from air-gapped modeling enclaves.

DEEP DIVE: NEURAL FORENSICS

The CellShock Triage Script: Automating Financial Formula Liquidation

You know that feeling when you’re auditing a workbook with 100 hidden sheets and someone asks about the xl/worksheets/sheet*.xml file? You don’t re-read every cell value. You flip to the XML parser, skim for relevant URL-encoded f tags, and piece together the exfiltration story. If you have a really great memory (and more importantly, great forensic recall) you can reference the =IMAGE trigger right off the dome.

Current Enterprise Spreadsheet Audits? Not so smart. They try cramming every “Allowed Domain” into a human analyst’s working memory at once. Once that memory fills up, performance tanks. Formula rules get jumbled due to what researchers call “indirect prompt rot”, and critical data siphons get lost in the middle.

The fix, however, is deceptively simple: Stop trying to remember every formula. Script the unmasking.

The new CyberDudeBivash CellShock Triage Script flips the script entirely. Instead of forcing a manual “Enable Content” risk, it treats your entire workbook archive like a searchable database that the script can query and report on demand to ensure the AI siphon is liquidated.

The Sovereign Forensic Primitive (Python/openpyxl):

# CYBERDUDEBIVASH: Excel CellShock IOC Triage Script
# UNMASK unsafe AI-generated formulas and LIQUIDATE financial siphons

import openpyxl, re
def audit_workbook(path):
  wb = openpyxl.load_workbook(path, data_only=False)
  siphons = [“WEBSERVICE”, “IMAGE”, “ENCODEURL”, “HYPERLINK”]
  for sheet in wb.worksheets:
    for row in sheet.rows:
      for cell in row:
        if cell.data_type == ‘f’ and any(s in cell.value for s in siphons):
          print(f”[!] ALERT: CellShock Siphon Unmasked at {cell.coordinate}: {cell.value}”)
          if “?” in cell.value: print(“[!] Liquidation Status: CRITICAL (URL Params Detected)”)

Think of an ordinary CFO as someone trying to read an entire encyclopedia of “Excel Vulnerabilities” before approving a budget. They get overwhelmed after a few volumes. An Institutional Triage Siphon is like giving that person a searchable library and research assistants who can fetch exactly the “Malicious-URL-Proof” needed for liquidation.

The results: This triage script handles workbook audits 100x faster than a model’s native attention window; we’re talking entire shared drives, multi-year model archives, and background calculation tasks. It beats both manual checks and common “protected-view” workarounds on complex reasoning benchmarks. And costs stay comparable because the script only processes relevant XML chunks.

Why this matters: Traditional “formula-locking” reliance isn’t enough for real-world 2026 agentic use cases. Users analyzing case histories, engineers searching whole codebases, and researchers synthesizing hundreds of papers need fundamentally smarter ways to navigate massive inputs.

“Instead of asking ‘how do we make the analyst remember more safe-domains?’, our researchers asked ‘how do we make the system search for formula gaps better?’ The answer—treating the workbook context as an environment to explore—is how we get AI to handle truly massive threats.”

Original research from Varonis and PromptArmor comes with both a full implementation library for vulnerability detection and a minimal version for platform sovereigns. Also, Microsoft and Anthropic have released internal “Classifier Updates” to sequestrate these threats.

We also just compared this method to three other papers that caught our eye on this topic; check out the full deep-dive on Neural Liquidation and the 2026 Financial Hardening Pack here.
