files: +- `appsec/api-security/api-top10-checklist.md` +- `appsec/threat-modeling/threat-actor-profiles.md` +- `compliance/soc2-gap/tsc-criteria.md` + +No skill uses `/references/`, `/scripts/`, or `/templates/` directories. Inline content that should be extracted includes: +- **Reference tables**: CWE mappings, NIST control IDs, CIS benchmark controls, MITRE ATT&CK mappings, CVSS metric tables, license compatibility matrices +- **Detection patterns**: Regex collections, grep patterns, Sigma rules, KQL/SPL queries +- **Templates**: Output report formats, remediation scaffolding, chain-of-custody forms, communication templates +- **Scripts**: SBOM generation commands, forensic collection commands, API query examples + +**Proposed fix:** Create `/references/`, `/scripts/`, `/templates/` directories per skill. Extract inline content. This is mechanical work — high volume, low risk. + +### Finding 2: R2 Verification — No Falsifiable Tests (15/45 FAIL) + +No skill defines an end-to-end verification test ("given input X, expect output Y"). The closest examples: +- `forensics-checklist`: SHA-256 hash chain verification (binary pass/fail) +- `detection-engineering`: Atomic Red Team true-positive/true-negative test +- `cve-triage`: SSVC decision tree (deterministic input→output) + +Most skills define output formats and severity classifications but never say: "Here is how to confirm the skill executed correctly." + +**Proposed fix:** Add a `## Verification` section to each skill with: +1. Expected behavior (what secure looks like) +2. Actual behavior check (how to confirm) +3. One falsifiable test case per skill + +### Finding 3: R3 Elegance — Three Major Overlap Clusters + +**Cluster A — AppSec Duplication:** +- `owasp-top-10-web` vs `secure-code-review`: ~80% content overlap (injection, auth, authz, crypto, error handling, SSRF, deserialization) +- Both produce near-identical findings when run on the same web app +- **Proposed fix:** `owasp-top-10-web` should delegate detection patterns to `secure-code-review` and focus on OWASP-specific gap analysis and compliance mapping + +**Cluster B — AI Security Duplication:** +- `agentic-top-10` vs `agent-security`: ~60% overlap (AG01↔Step1, AG05↔Step7, AG08↔Step3) +- `llm-top-10` LLM01 vs `prompt-injection`: ~70% topic overlap +- `llm-top-10` LLM03 vs `model-supply-chain`: ~60% topic overlap +- **Proposed fix:** `llm-top-10` should be a survey/router that delegates to specialized skills. `agentic-top-10` and `agent-security` need clear boundary definitions + +**Cluster C — Identity Umbrella:** +- `iam-review` 7-step process overlaps with 4 other identity skills (access-review, privileged-access, zero-trust-assessment, rbac-design) +- **Proposed fix:** `iam-review` should be the orchestrator that delegates to specialized skills, not a superset + +### Finding 4: R1 System Layer — Domain Split + +| Domain | R1 Performance | Pattern | +|---|---|---| +| SecOps | 4/4 PASS | KQL/SPL queries, Sigma rules, Event ID tables | +| Incident Response | 4/4 PASS | CLI commands, decision trees, formulas | +| Network | 3/3 PASS | Regex patterns, config examples, detection thresholds | +| Cloud | 5/5 PASS | HCL/Bicep patterns, grep commands, CIS checklists | +| AppSec | 5/5 PASS | Code patterns, ASVS tables, grep patterns | +| DevSecOps | 1/4 PASS | secrets-management strong; others have patterns but not executable | +| Vuln Mgmt | 0/4 PASS | Structured tables but no executable automation | +| Identity | 0/5 PASS | Prose rubrics and maturity matrices, no executable content | +| AI Security | 2/6 PASS | model-supply-chain and agent-security strong; others prose-heavy | +| Compliance | 0/5 PASS | Templates and checklists but no executable patterns | + +**Proposed fix:** Bring Identity, Compliance, and AI Security skills up to the standard set by SecOps/IR/Network. Add grep/glob patterns, detection regex, and executable verification steps. + +### Finding 5: R5 Gotchas — Quality Split + +- **Strong gotchas** (21 PASS): SecOps, IR, Network, and vuln-mgmt skills have precise, technically specific gotchas with real-world examples +- **Weak gotchas** (20 PARTIAL): Compliance and Identity skills have "Common Pitfalls" that are operational advice, not false-positive patterns or precision traps +- **Missing gotchas** (4 FAIL): `dependency-scanning`, `pipeline-security`, `iam-review`, and `llm-top-10` have no gotchas section + +**Proposed fix:** Standardize gotchas format across all skills: (1) False positive patterns, (2) Precision traps, (3) Exploit pattern lessons.

The root cause was that each plugin operated with the full permissions of the user session, and no isolation existed between plugin contexts. This pattern recurs in every agent framework that does not enforce tool-level scoping. + +## AG02: Anthropic Tool Use Manipulation and LangChain CVE-2023-29374 + +The 2024 Anthropic research paper on tool use showed that Claude, when given a code execution tool, could be manipulated via indirect prompt injection (embedded in a document it was summarizing) to execute arbitrary code rather than the analysis code the user requested. The tool itself was functioning as designed -- the abuse was in what the agent chose to execute through it. Similarly, the 2023 LangChain arbitrary code execution vulnerability (CVE-2023-29374) demonstrated that agent-controlled inputs to code execution tools are a persistent, high-severity risk. + +## AG03: UIUC CrewAI Privilege Escalation (2024) + +Researchers from UIUC demonstrated a multi-agent privilege escalation attack where a compromised "research" agent in a CrewAI system sent crafted messages to an "executor" agent, convincing it to run commands that the research agent was not authorized to execute directly. The executor agent trusted the research agent's messages as legitimate task instructions because no inter-agent authentication existed. This is the agentic equivalent of a confused deputy attack. + +## AG04: ChatGPT Persistent Memory Poisoning (2024) + +Researchers demonstrated a persistent memory poisoning attack against a ChatGPT instance with memory enabled. By embedding instructions in a shared document the user asked the AI to summarize, the attacker caused the AI to store a directive in its persistent memory that altered its behavior in all future conversations -- effectively a persistent backdoor.

Cross-Agent Attacks (2023) + +In the Greshake et al. paper "Not What You've Signed Up For" (arXiv:2302.12173), researchers demonstrated cross-agent attacks in LangChain-based multi-agent systems where a compromised web-browsing agent injected manipulated content that was consumed by a downstream planning agent.

Java -- Weak Session Management (CWE-287) + +```java +// VULNERABLE: predictable session identifier +String sessionId = "session-" + System.currentTimeMillis(); +response.addCookie(new Cookie("SESSIONID", sessionId)); +``` +Remediation: Use the framework's built-in session management (e.g., `HttpSession`) which generates cryptographically random tokens. + +## 8.

Python -- Unsafe Deserialization (CWE-502) + +```python +# VULNERABLE: deserializing untrusted data with pickle +import pickle +data = pickle.loads(request.data) +``` +Remediation: Never use `pickle` on untrusted input. Use JSON or a schema-validated format. If object serialization is required, use a safe library with type restrictions. + +## 13. Java -- Unsafe Deserialization (CWE-502) + +```java +// VULNERABLE: deserializing arbitrary objects from user input +ObjectInputStream ois = new ObjectInputStream(request.getInputStream()); +Object obj = ois.readObject(); +``` +Remediation: Avoid native Java deserialization of untrusted data.

scan can run in parallel -- they examine independent attributes and do not depend on each other's results. Similarly, public exposure checks and network security checks can run concurrently. + +--- + +### Precision Requirements -- Reducing False Positives + +Before including any finding in the report, apply the following verification gate. This is critical: static IaC analysis is prone to high false positive rates. Every finding must pass these checks. + +1. **Require specific file:line reference for every finding.** Only flag a misconfiguration when you can cite the exact file path, line number, and resource block where the insecure configuration exists. Findings that reference a "missing resource" (e.g., "no `aws_s3_bucket_public_access_block` exists") are only valid if there is a corresponding resource that is demonstrably exposed without it. + +2. **Distinguish between default values that are insecure vs. intentional configurations.** Many cloud providers have changed defaults over time. Before flagging a missing attribute: + - Check the provider version constraints in the project (e.g., `required_providers` block). + - If the provider version defaults to a secure value for the missing attribute, do not flag it. Only flag explicitly insecure values that are set in the configuration. + - Example: AWS S3 buckets encrypt by default since January 2023. Do not flag missing `server_side_encryption_configuration` unless the provider version predates this change. + - Example: `enable_https_traffic_only` defaults to `true` in AzureRM 3.0+. Only flag `enable_https_traffic_only = false`. + +3. **Distinguish "security misconfiguration" from "best practice recommendation."** A security misconfiguration creates a concrete, exploitable attack path. A best practice recommendation improves defense-in-depth but its absence alone is not exploitable. + - `publicly_accessible = true` on an RDS instance is a **security misconfiguration**. + - Missing `versioning { enabled = true }` on an S3 bucket is a **best practice** (does not create an attack path). + - `image_tag_mutability = "MUTABLE"` on ECR is a **best practice** for supply chain hygiene, not a directly exploitable misconfiguration -- report as Low or Informational, not Medium/High. + - Missing CMEK on a compute disk where Google-managed encryption is active is a **best practice**, not a misconfiguration. + +4. **Consolidate duplicate findings for the same resource pattern.** If the same misconfiguration appears across multiple instances of the same resource type (e.g., 7 MSSQL servers with the same hardcoded password, or 9 RDS clusters without encryption), report it as ONE finding with all affected locations listed. Do not generate separate findings for each instance. + +5. **Consolidate cross-cloud duplicates of the same resource misconfiguration.** If the same logical finding (e.g., "SSL enforcement disabled on database server") appears in both the Azure and AWS sections, it may be reported separately per cloud, but each cloud finding must still pass all verification checks independently. Do not inflate finding counts by reporting the same issue at multiple abstraction levels (e.g., do not report both "MySQL SSL disabled" and "Encryption in transit missing on database" for the same resource). + +6. **Severity must reflect real-world exploitability.** Assign severity based on actual attack impact: + - **Critical/High:** The misconfiguration directly enables unauthorized access, data exposure, or credential compromise without requiring additional attack steps. Examples: hardcoded credentials, `0.0.0.0/0` on management ports, public database endpoints, wildcard IAM policies. + - **Medium:** The misconfiguration weakens a defense layer but requires additional conditions to exploit. Examples: missing logging, missing key rotation, unpinned provider versions. + - **Low/Informational:** Best practice deviations that improve posture but whose absence is not directly exploitable. Examples: missing versioning, mutable image tags, missing CMEK where provider encryption exists, dashboard enabled. + --- +### Findings Verification Checklist + +Before finalizing findings, apply this checklist to each candidate finding: + +- [ ] **Resource block exists in configuration** -- the finding references a specific resource block that you confirmed exists in the IaC files (not a hypothetical or inferred resource). +- [ ] **Misconfiguration is in the actual config, not inferred** -- you used `Read` to verify the insecure setting is explicitly present in the code, or confirmed via provider documentation that the absent attribute defaults to an insecure value for the provider version in use. +- [ ] **No compensating control present** -- you checked for related resources that mitigate the risk (e.g., a public S3 bucket behind `aws_s3_bucket_public_access_block`, an open security group attached only to a private subnet, a database with public access but restricted by `security_ips`/firewall rules). +- [ ] **Severity reflects real-world exploitability** -- Critical/High findings represent directly exploitable attack paths; best practice gaps are Low/Informational. +- [ ] **Finding is not a duplicate** -- the same misconfiguration is not already reported in another finding covering the same resource or a consolidated multi-resource finding. + +**Discard any finding that fails two or more checklist items.** Findings that fail one item should be downgraded to Informational. --- @@ -203,7 +245,7 @@ Produce the final report using the structure defined in the Output Format sectio ### Checkov / tfsec / KICS Rule Equivalents -This skill applies checks equivalent to the following high-impact rules: +This skill applies checks equivalent to the following high-impact rules (summary -- full mapping in [references/scanner-rule-mapping.md](references/scanner-rule-mapping.md)): | Tool | Rule | Description | |------|------|-------------| @@ -219,6 +261,12 @@ This skill applies checks equivalent to the following high-impact rules: | KICS | 3406e4d3 | S3 public ACL | | KICS | 5b4f3042 | Unrestricted security group | +### File References + +- **Scanner rule mapping:** Full Checkov/tfsec/KICS rule mapping table extracted to [references/scanner-rule-mapping.md](references/scanner-rule-mapping.md). +- **Secret detection patterns:** 25+ secret detection regex patterns extracted to [references/secret-patterns.md](references/secret-patterns.md). +- **Tool rules:** Detection patterns, vulnerable code examples, and remediation guidance in [tool-rules.md](tool-rules.md). + --- ## Common Pitfalls @@ -265,4 +313,6 @@ This skill applies checks equivalent to the following high-impact rules: ## Changelog +- **1.0.2** -- Extract scanner rule mapping to `references/scanner-rule-mapping.md` and secret detection patterns to `references/secret-patterns.md`.

For API-only applications (no browser-rendered content), this is frequently a false positive: API responses are consumed by programmatic clients that do not use browser caching. However, do NOT blanket-IGNORE rule 10015 -- it is valid for applications serving HTML, JavaScript, or any content rendered in browsers. The correct approach is to set rule 10015 to IGNORE in the ZAP rules TSV only for API-only scan contexts, while keeping it active for web application scans. + +7. **WAF bypass patterns affecting DAST scan accuracy.** If the target application sits behind a WAF (Cloudflare, AWS WAF, Azure Front Door), the WAF may block ZAP's active scan payloads before they reach the application. This creates a false sense of security: the DAST report shows no injection findings, but the application itself may be vulnerable. To get accurate results: (a) scan against the origin server directly (bypassing WAF) in staging environments, or (b) allowlist the scanner's IP in the WAF for the scan window, or (c) document that DAST results reflect WAF+app combined posture, not application-only posture.

The risk is specifically when `pull_request_target` is combined with `actions/checkout` referencing `github.event.pull_request.head.sha` or executes code from the PR branch. Do not flag `pull_request_target` as CICD-SEC-4 if the workflow never checks out or executes PR-sourced code. + +2. **Workflow-level vs. job-level `permissions` is a precision trap.** A workflow may declare `permissions: {}` (empty, read-only) at the top level while individual jobs override with broader permissions. Conversely, a workflow with no top-level `permissions` block defaults to the repository's token permissions (often read-write). When evaluating CICD-SEC-2, check both workflow-level AND job-level `permissions` blocks. The effective permission is the intersection of the repository default and the most specific declaration. Reporting "no permissions block" as a finding is correct only if no job-level permissions exist either. + +3. **The 2024 Codecov supply-chain breach is a canonical CICD-SEC-8 lesson.** The Codecov Bash Uploader was compromised via a modified script hosted on Codecov's infrastructure, exfiltrating CI environment variables (including secrets) from thousands of repositories. This demonstrates that even "trusted" third-party CI integrations are supply-chain attack vectors. When evaluating CICD-SEC-8, check whether third-party upload/reporting tools (Codecov, Coveralls, etc.) are pinned to SHA and whether their outputs are validated. The Codecov pattern is: a trusted action/script is silently replaced with a malicious version that reads `env` and exfiltrates secrets. + +--- + +## Verification + +**Falsifiable test:** If a workflow has `permissions: write-all` and no CICD-SEC-2 finding, the review failed. + +To verify the skill produced correct output, check: + +1.
