What a "Script Kiddie + AI" Actually Looks Like

Abstract descriptions of AI-lowering-the-bar can feel unconvincing. Let me make it concrete: here is a realistic attack scenario that an intermediate-skill attacker with AI tools could execute in 2025 — and the equivalent scenario from 2020 that would have required a senior professional.

The attacker has: intermediate security knowledge (equivalent to a mid-level CTF player), access to AI tools (Cursor, Gemini CLI, HexStrike-AI or equivalent), and a target organization to investigate.


Day 1 — Target Research and Tool Preparation

2020 Version (Senior Professional Required)

A senior attacker with OSINT experience manually:

  • Queried Shodan with domain-specific filters they knew from experience
  • Ran theHarvester for email enumeration
  • Used Sublist3r or OWASP Amass for subdomain discovery
  • Correlated results manually across tools
  • Built a credential stealer using C++ Windows API knowledge they had accumulated over years

Time required: Multiple days. Several separate skill domains.

2025 Version (Intermediate Skill + AI)

Using HexStrike + Cursor for OSINT, the attacker provides one email address and lets the AI:

  • Query Shodan for exposed services and IP ranges
  • Run theHarvester for employee email enumeration
  • Execute Sublist3r and OWASP Amass for subdomain discovery
  • Cross-reference SpiderFoot against breach databases and social platforms
  • Automatically correlate everything into a digital footprint map

Simultaneously, using Cursor AI:

  • Specify: "Build a credential stealer that harvests Chrome saved passwords and sends them to a remote endpoint, avoiding common EDR behavioral signatures"
  • AI iterates on implementation, tests against detection, and produces a functional binary

Time required: Hours. No multi-year skill prerequisite.

The key output that differs from 2020: a custom-built tool with no existing detection signatures. The 2020 attacker, if they lacked development skills, would have used Mimikatz — which every EDR vendor detects immediately. The 2025 attacker has a novel binary.


Day 2 — Initial Access

2020 Version

Crafting convincing spearphishing required either social engineering expertise or purchasing access from a specialized operator. Creating a malicious macro document that evaded email gateway sandboxes required understanding of sandbox evasion techniques.

2025 Version

Using data gathered by AI in Day 1:

  • AI drafts personalized spearphishing emails per target using LinkedIn role data and corporate context
  • AI generates a macro-enabled document with sandbox evasion techniques selected based on what was documented as having weak Sigma coverage
  • AI configures C2 server with a custom malleable profile tuned to blend with the target organization's normal SaaS traffic patterns (based on Shodan/Censys fingerprinting of their infrastructure)

The AI's knowledge of documented detection patterns (from public Sigma rules, ATT&CK, vendor blogs) enables designing the initial access chain with evasion built in, not bolted on.


Day 3 — Exploitation and Post-Compromise

2020 Version

Post-compromise in 2020 required: Active Directory expertise for enumeration, lateral movement technique knowledge, credential dumping expertise, and operational discipline to not trigger behavioral alerts.

A Tier 3 attacker would have used known tools (Mimikatz, BloodHound, PsExec) and likely triggered EDR alerts on well-defended networks.

2025 Version

Using HexStrike-AI connected through MCP:

  • AI-guided post-exploitation: identify high-value accounts and AD topology without running BloodHound directly (an AI-suggested alternative with weaker EDR coverage)
  • Custom persistence mechanism the AI suggested for its detection gap compared to common Registry Run Key approaches
  • Credential harvesting through a technique selected for its minimal Sigma rule coverage
  • Lateral movement timed to match normal business hours based on the organization's public timezone information

The result: An attack that uses:

  • No known-malicious binary signatures
  • No documented C2 profile patterns
  • Techniques specifically selected to avoid the most common detection rules

Required skill to execute in 2025: Intermediate. Someone who understands what each step accomplishes.

Required skill to execute in 2020: Senior offensive security professional. 5+ years experience across multiple specialty domains.

What This Means for Your SOC

When you receive an alert tomorrow and classify the actor as "likely commodity/low-skill based on initial TTPs," that classification is now less reliable.

The indicators that used to imply low skill — using known tools, predictable patterns, recognizable signatures — are now optional choices. An actor who would have been Tier 3 in 2020 can choose not to use known tools in 2025. Not because they developed the skill — because AI provides it.

The threat model recalibration: Raise your baseline assumption about adversary capability. A mid-market organization being targeted by what looks like a low-tier actor may be facing something more capable than the initial TTPs suggest. The absence of known tool signatures is no longer reliable evidence of a low-skill actor — it may simply mean they used AI to generate a custom tool.
