conducting-social-engineering-pretext-call

conducting-social-engineering-pretext-call is a skill for Claude Code from 26zl/cybersec-toolkit. It costs 35 tokens per session (1,758 once invoked), scanned A, original, MIT.

A guide to authorized vishing exercises, in which testers call employees while pretending to be trusted people or organizations. The exercises assess whether employees reveal information, perform unsafe actions, or grant access.

In plain words
What is it for?
Use it to plan and conduct approved pretext phone calls, record the results where permitted, and assess employee responses.
Why use it?
It helps organizations test human security controls and identify weaknesses in verification procedures. The results can show where security-awareness training needs attention.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

conducting-social-engineering-pretext-call scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/agent.py, scripts/process.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Conducting Social Engineering Pretext Call

Overview

A pretext call (vishing) is a social engineering technique where an attacker impersonates a trusted authority figure over the phone to manipulate targets into divulging sensitive information, performing actions, or granting access. In red team engagements, pretext calls test the human element of security controls, measuring employee adherence to verification procedures and security awareness training effectiveness. MITRE ATT&CK maps this to T1566.004 (Phishing for Information: Voice) and T1598 (Phishing for Information).

When to Use

  • When conducting security assessments that involve conducting social engineering pretext call
  • When following incident response procedures for related security events
  • When performing scheduled security testing or auditing activities
  • When validating security controls through hands-on testing

Prerequisites

  • Written authorization specifying social engineering scope and boundaries
  • List of approved target employees (usually provided by client)
  • OSINT research on targets and organization
  • Spoofed caller ID capability (authorized for testing)
  • Call recording equipment (with legal consent as required)
  • Pretext scenarios approved by client

T1589 Gather Victim Identity Information Reconnaissance
T1591 Gather Victim Org Information Reconnaissance

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
