RANSOMWARE READINESS • INCIDENT RESPONSE • DATA EXFILTRATION

Situation: You *will* be hit by ransomware. Your “prevention” tools (EDR, Firewall) *will* fail. The *only* question that matters is: What is your Mean Time to Respond (MTTR)? A 24-hour downtime is a disaster. A 24-day outage is a company-ending event. Your “backup” plan is not enough.

This is a decision-grade CISO brief. We are moving past “prevention” (which fails) to “resilience.” This is the CyberDudeBivash Ransomware Readiness Framework. We’re providing the *exact* 20-point checklist our experts use to audit a company’s readiness, from EDR bypasses to Data Exfiltration. We are also offering a Free 30-Minute Assessment to run this playbook *for* you.

TL;DR — Your “backup plan” is not an IR plan.

• The Myth: “We have backups, so we’ll just restore.”
• The Reality: “Double Extortion.” Attackers *steal (exfiltrate)* your PII/IP data *before* they encrypt. Your backup *does not* stop them from leaking your “crown jewels.”
• The “Ransomware TTP”: 1) Phish/Credential Stuffing → 2) EDR Bypass (LotL) → 3) `vssadmin delete shadows` (Kills your backups) → 4) Covert Data Exfil → 5) Encrypt.
• The “Legal Trap”: Paying is now *illegal*. The Lytvynenko Case Study proves OFAC fines for paying sanctioned APTs are *worse* than the ransom.
• THE ACTION: You *must* shift from “Prevention” to “Readiness & Response.” This requires a 24/7 MDR team and a human-led IR (Incident Response) plan.

TTP Factbox: Ransomware Kill Chain

Kill Chain Phase	Attacker TTP	Your Defense (Our Service)
Initial Access	Phishing / Credential Stuffing	PhishRadar AI / SessionShield
Defense Evasion	“Living off the Land” (LotL)	24/7 MDR (Threat Hunting)
Data Exfiltration	Covert C2 (DNS Tunneling)	24/7 MDR (Threat Hunting)
Impact	`vssadmin delete shadows`	MDR + Active Response (IR)

Critical Financial RiskEDR Bypass TTPData Exfiltration & Extortion

Risk: Your legacy backup plan is obsolete. This is no longer an “encryption” problem. It is a Data Exfiltration and Corporate Espionage crisis. You are *not* ready.Contents

Phase 1: Why Your “Prevention” Stack *Will* Fail (The LotL Bypass)

As a CISO, you have a “defense-in-depth” stack: SEG, EDR, Firewall. Attackers *know* this. Their TTPs are now 100% focused on bypassing these tools by *exploiting trust*.

This is the “Living off the Land” (LotL) attack. Your EDR is *whitelisted* to trust `powershell.exe`, `wmic.exe`, and your `RMM_Agent.exe`. The attacker, after an initial phish, *only* uses these “trusted” tools.

Your EDR sees `powershell.exe` running. It logs it as “noise.” It *doesn’t* see the fileless, in-memory C2 beacon it’s *actually* running.
Your Firewall sees `powershell.exe` making an HTTPS connection. It *allows* it, assuming it’s a “trusted” admin script.
Your SIEM is flooded with 10,000 “benign” alerts, and your 9-to-5 SOC *misses* the *one* anomalous connection that signals the breach.

Your “prevention” stack is a “detection” stack. And a “detection” stack without a 24/7 human MDR team to hunt the “noise” is just a *logging server* for your own breach.

The CISO Mandate: You *must* assume prevention will fail. You *must* shift your budget and mindset from 90% “Prevention” to 50% “Detection & Response.” This means a behavioral EDR (like Kaspersky EDR) paired with a 24/7 human MDR team (like ours).

Phase 2: The *Real* Kill Chain (Data Exfil *Before* Encryption)

Your “Ransomware Plan” is probably just a “Backup Restore Plan.” This is a fatal mistake. Ransomware is no longer an “encryption” attack; it’s a “Double Extortion” data breach.

Stage 1: Initial Access (The Phish / 0-Day)

The attacker gets a foothold, often via an AI-powered spear-phish or a 0-day (like the recent WSUS RCE). They are “in” as a low-privilege user.

Stage 2: Defense Evasion & Lateral Movement

They use LotL TTPs (PowerShell) to find your Domain Controller, escalate privileges (e.g., via CVE-2025-24990), and get Domain Admin. Your EDR, if it’s not tuned by an expert MDR, misses this.

Stage 3: The “4TB Question” (Covert Data Exfil)

This is the *real* attack. The attacker *does not* encrypt. They *sit silently* for weeks. They `tar.gz` your “crown jewels” (PII, IP, CUI, M&A docs) and exfiltrate them “low-and-slow” using *covert channels* your DLP is blind to:

• DNS Tunneling: Hiding data in “trusted” DNS requests.
• API Tunneling: Hiding data in “trusted” API calls to Google Drive or api.anthropic.com (Claude).

Stage 4: Impact (The “Noise”)

*Only* after your 4TB of data is secure in their hands do they run `vssadmin delete shadows` (killing your backups) and deploy the ransomware. The encryption is just *loud noise* to cover their tracks and give them a *second* payday.

Exploit Chain (Engineering)

This is a “Detection & Response” problem. The kill chain is 100% behavioral.

• Trigger: Phishing (LNK) or Credential Stuffing (BYOD).
• TTP 1: `powershell.exe -e …` (Fileless beacon).
• TTP 2: `powershell.exe` spawns `whoami.exe`, `net.exe` (Recon).
• TTP 3: `powershell.exe` makes high-volume `nslookup` calls (DNS Tunneling Exfil).
• TTP 4: `powershell.exe` runs `vssadmin.exe delete shadows` (Pre-Ransomware).
• Patch Delta: There is no “patch.” The “fix” is MDR Threat Hunting to *detect* this behavioral chain.

Phase 3: The “To Pay or Not to Pay” Legal Trap (OFAC & DPDP)

This is the “General Counsel’s Nightmare.” You’re breached. The Lytvynenko Case Study proves you are now in a “no-win” scenario.

• The OFAC Trap: Your IR team (like ours) *must* attribute the attack. If the RaaS group (BlackCat, etc.) is a *front* for a sanctioned APT (Lazarus, BRONZE BUTLER), and you *pay* the ransom, you have just committed a *crime*. The OFAC fine can be *double* the ransom.
• The DPDP/GDPR Trap: You *must* report the PII data exfiltration. The attacker *will* leak it anyway. You are now facing a *250-Crore fine* (DPDP) or 4% of global revenue (GDPR) for the *data breach*, regardless of whether you pay.

The “cost” of the breach is no longer the “ransom.” It’s the *fine*. The *only* winning move is to *never be in this room*. This means *preventing the data exfiltration* in the first place.

The CISO Mandate: The “Ransomware Readiness” Audit (The 20-Point Plan)

This is the CyberDudeBivash Ransomware Readiness Framework. This is what we run. How many can you *honestly* check “yes” on?

Pillar 1: Prevention (The “Lock”)

• Do you mandate Phish-Proof MFA (Hardware Keys) for *all* admins and C-suite?
• Do you *block* LNK/HTA/VBS files at your email gateway?
• Do you *block* `powershell.exe` from running in user-writable paths (WDAC/AppLocker)?
• Do you have an AI-powered phish defense (like PhishRadar AI)?

Pillar 2: Detection (The “Alarm”)

• Do you have a *behavioral* EDR (like Kaspersky) that logs *all* process chains?
• Do you have a 24/7/365 human SOC/MDR team (like ours) to *hunt* that telemetry?
• Do you have *active* hunt queries for the `java.exe -> powershell.exe` TTP?
• Do you have *active* hunt queries for DNS Tunneling?
• Do you have Session Monitoring (like SessionShield) to detect the *post-login* hijack?

Pillar 3: Response & Resilience (The “Plan”)

• Do you have an IR plan *and* a 24/7 *retainer* with an IR provider (like us)?
• Are your backups *truly* immutable (offline, air-gapped, or Cloud Object-Lock)?
• Have you *tested* a full bare-metal restore?
• Have you *verified* this entire stack with a human-led Red Team engagement?

The FREE 30-Minute Ransomware Readiness Assessment (Our Offer)

If you hesitated on *any* of those points, you are not “ready.” You are “lucky.”

The CyberDudeBivash team—the same IR hunters and Red Teamers who respond to these breaches—are offering a Free 30-Minute Ransomware Readiness Assessment for qualified organizations.

This is not a “sales pitch.” This is a *no-fluff, expert-led* planning session. We will:

1. Run *this exact CISO framework* against your current stack.
2. Analyze your “prevention” layer (MFA, EDR) for *obvious* TTP bypasses.
3. Analyze your “detection” layer (SIEM/MDR) for the *behavioral* hunting gaps.
4. Analyze your “response” layer (IR/Backups) for *legal* and *procedural* failures.

You will leave with a confidential, 3-point action plan identifying your *most critical* vulnerabilities. We find the “E-Mail Security 0-Day” or the “ActiveMQ flaw” in your network *before* the attacker does.

Stop Guessing. Start Preparing.
Your board is asking “Are we secure?” Get the *real* answer.

FAQ

Q: What is “Double Extortion” ransomware?
A: It’s a two-stage attack. 1) The attacker *steals* (exfiltrates) your sensitive data. 2) The attacker *encrypts* your files. They now have two ways to make you pay: the decryption key, and a promise *not* to leak your stolen data (like Qantas’s) to the dark web.

Q: We have backups. Why do we need this?
A: Backups *do not* solve Data Exfiltration (Double Extortion). They also *fail* when the attacker runs `vssadmin delete shadows` or encrypts the backup server first. A readiness plan *verifies* your backups are immutable.

Q: Why is the 30-Min Assessment free?
A: CyberDudeBivash is a leader in Ransomware Defense. We run this assessment because 9/10 companies we audit are *critically* vulnerable to LotL and data exfil TTPs. We believe the *proof* of this risk is the single most valuable service we can offer. It’s the start of your journey to true resilience.

Q: What is the “Lytvynenko Case Study”?
A: It’s our internal postmortem of a real-world scenario where a company *paid* a $10M ransom, only to be *fined* $20M by OFAC because the RaaS gang was a *front for a sanctioned nation-state*. This is the *new* CISO legal trap.
