Introduction
Most “AI pentest” content stops at a scan screenshot.
This engagement did not.
Using Cursor as the control plane (agent orchestration) and HexStrike-AI as the execution plane (tooling via MCP), the session started as a “single target full PT” and rapidly expanded into a comprehensive assessment of the entire subnet. The result was measurable:
- 7 hosts discovered
- 3 hosts compromised
- multiple critical vulnerabilities confirmed
- sensitive data exfiltrated
- and a structured report produced at the end
All captured in a raw, decision-by-decision log and consolidated into a final network report.
After a lot of testing, I think that HexStrike + Cursor is the most efficient couple — because the agent can drive the workflow (including pivots and troubleshooting) while HexStrike runs the heavy tooling.

Scenario and objective
Initial request (lab): full penetration test against 172.16.59.144 with expanded objectives that included persistence, multiple shell types, credential attacks, lateral movement, C2 behavior, and encryption simulation.
Network segment later assessed: 172.16.59.0/24.
Tooling model: Cursor + MCP + HexStrike
The way to read this engagement is simple:
- Cursor agent = planner + operator
- HexStrike MCP tools = execution
- The workflow is evidenced by MCP tool calls in the log (e.g., recon scans, SMB enumeration, web enumeration, vuln scanning).
The key value: the agent didn’t just “run a scan.” It kept making decisions:
- which vector is higher ROI
- which host is worth deeper enumeration
- when to pivot from single target to subnet discovery
- and how to proceed when tools/params failed
That decision record is exactly what makes the log useful.

COMMAND: smbclient //172.16.59.140/secrets -N -c "ls"
COMMAND: smbclient //172.16.59.140/root -N -c "ls"
REASONING: Test which shares allow anonymous access
RESULTS:
- public: Accessible (empty)
- secrets: Accessible (empty listing, but may have files)
- root: Accessible - ENTIRE FILESYSTEM EXPOSED!
DECISION: This is extremely critical. The root share exposes the entire
filesystem via anonymous SMB access. This is a catastrophic misconfiguration.
ACTION: Explore root share
COMMAND: smbclient //172.16.59.140/root -N -c "ls"
REASONING: See what's accessible in root share
RESULTS: Can see entire filesystem structure including:

================================================================================
DECISION LOG
================================================================================
KEY DECISIONS MADE DURING TESTING:
1. DECISION: Start with broad reconnaissance
REASONING: Need to understand attack surface before focusing on specific vectors
RESULT: Identified multiple attack vectors (FTP, SMB, HTTP, RDP)
2. DECISION: Prioritize FTP anonymous access
REASONING: Anonymous FTP often contains misconfigurations and leaked data
RESULT: Found leaked credentials that led to full compromise
3. DECISION: Test credentials immediately on SMB
REASONING: SMB is primary Windows service, credentials likely to work there
RESULT: Obtained administrative access
4. DECISION: Deploy multiple persistence mechanisms
REASONING: Single persistence method can be detected/removed, multiple methods
increase chances of maintaining access
RESULT: Four different persistence methods deployed
5. DECISION: Create multiple shell types
REASONING: Different shells have different capabilities and detection profiles
RESULT: Meterpreter, PowerShell, and CMD shells available
6. DECISION: Use XOR encryption for ransomware simulation
REASONING: Simple encryption method for demonstration, not production-grade
RESULT: Encryption script deployed successfully
7. DECISION: Scan entire network segment for lateral movement
REASONING: User requested lateral movement, need to find other targets
RESULT: Discovered 7 hosts, compromised 3
8. DECISION: Exploit PHP RCE immediately when found
REASONING: RCE vulnerabilities are high-value, should be exploited quickly
RESULT: Gained access to METASPLOITABLE
9. DECISION: Explore anonymous SMB root share thoroughly
REASONING: Root filesystem access is extremely critical, need to document fully
RESULT: Found additional credentials and sensitive data
10. DECISION: Test all discovered credentials across network
REASONING: Credential reuse is common, credentials may work on multiple hosts
RESULT: Credentials only worked on original target

Troubleshooting patterns (what actually broke, and how the workflow recovered)
Your log includes a clean “Errors and troubleshooting” section that is worth calling out because it reflects the main productivity multiplier:
- Some HexStrike tools/parameters were unavailable → the workflow switched to standard/basic alternatives rather than stopping.
- SMB path/format quirks during file operations → handled by using correct share semantics and Windows path formatting.
- SSH compatibility issues (key algorithms) → mitigated via client-side compatibility options.
- MySQL SSL requirement blocked quick probing → recorded and moved on.
This is exactly where Cursor + HexStrike shines: the agent treats tooling friction as a normal event and keeps progressing.
Findings summary (as reported)

Conclusion
This lab engagement is the clearest demonstration of why AI-assisted operations are already a force multiplier:
- It started with a single Windows host.
- It discovered credentials through exposure instead of brute force first.
- It converted access into proven impact (sensitive data access).
- It pivoted into subnet discovery and validated lateral movement realities.
- It compromised three different machines through three different root causes:
- leaked creds,
- default creds / known-vuln surface,
- anonymous filesystem exposure.
And it did all of that with a documented decision record and a clean final report.
After a lot of testing, I stand by it: HexStrike + Cursor is the most efficient couple for this style of end-to-end workflow — because it’s not “AI that talks,” it’s AI that operates.

If you want to reproduce this safely (lab):
- keep the scope local and explicit,
- log everything,
- and treat each compromise as a lesson in root cause , not “cool exploitation.”

Known Limitations
caution
- Results are specific to the lab configuration used; outcomes will differ on hardened or patched targets.
- AI tool selection is heuristic — novel service configurations may require re-prompting or manual follow-up.
- All walkthroughs ran in an isolated VirtualBox/VMware network, not a production environment.
- Timing and success rates vary with host CPU, RAM, and network latency.
- Some tool outputs are truncated in the screenshots; full output was reviewed live during the session.
