Analyzes email security including phishing dissection, SPF/DKIM/DMARC authentication checks, BEC fraud patterns, and OAuth token abuse research for authorized reviews.

Configure Proofpoint Targeted Attack Protection (TAP) to detonate suspicious attachments and URLs in isolated sandboxes, integrate with email flow, analyze reports, and tune detection policies.

Audits email domain deliverability setup (SPF, DKIM, DMARC, MX records, blacklists, TLS) and generates health score (0-100) with prioritized fix list. Checks bulk sender compliance against Google/Yahoo/Microsoft 2024-2026 requirements. Provides DNS records to add/update. Use when user asks to audit, check, or analyze email deliverability, domain health, or inbox placement.

Configure email security gateways like Microsoft Defender, Proofpoint, and Mimecast to detect and block targeted spearphishing attacks using impersonation protection, URL detonation, and attachment sandboxing.

Discover hidden directories, files, APIs, and administrative interfaces by enumerating URLs and testing authentication enforcement during authorized security assessments.

Enumerate DNS records, attempt zone transfers, brute-force subdomains, and map DNS infrastructure during authorized reconnaissance to identify attack surface, misconfigurations, and information disclosure in target domains.

Prevent domain spoofing and phishing by implementing SPF, DKIM, and DMARC email authentication protocols with DNS configuration and validation.

Deploy and configure Proofpoint Email Protection as a secure email gateway to detect and block phishing, malware, BEC, and spam before messages reach user inboxes.

Execute a phased DMARC rollout from p=none monitoring through p=quarantine to p=reject enforcement, ensuring all legitimate email sources are authenticated before blocking unauthorized senders.

Detect compromised O365 and Google Workspace email accounts by analyzing inbox rule creation, suspicious sign-in locations, mail forwarding rules, and unusual API access patterns via Microsoft Graph and audit logs.

Verify feature, bug, UI, API, mobile, security, or deployment work against acceptance criteria.

Validates Claude Ads contracts, bundles, scores, runs, capabilities, repositories, and releases with deterministic checks and recovery steps.

Enforce API input/output contracts using OpenAPI specifications and JSON Schema to prevent injection, mass assignment, and data leakage attacks.

Parse and analyze email headers to trace the origin of phishing emails, verify sender authenticity, and identify spoofing through SPF, DKIM, and DMARC validation.

Enforces identity-based network access with 802.1X, RADIUS authentication, dynamic VLAN assignment, and endpoint posture assessment using PacketFence.

Exploit Active Directory Certificate Services (AD CS) misconfigurations, specifically ESC1. By requesting a certificate based on a overly permissive template that allows the enrollee to supply a Subject Alternative Name (SAN), an attacker can impersonate highly privileged users (like Domain Admins) and seamlessly escalate privileges across the entire AD environment.

Audits email infrastructure security by testing SPF, DKIM, DMARC, open relay, spoofing resilience, MTA-STS, TLS-RPT, and SMTP configuration using standard security tools.

Verifies claims, articles, screenshots, and URLs through source-grounded analysis with an evidence ledger, source credibility evaluation, and manipulation detection. Supports quick checks, full fact-check cards, two-source comparisons, and prebunking in multiple languages and policy contexts.
