Many companies believe they are protected because they have MFA, EDR, WAF, SIEM and recurring vulnerability scans. Real attackers rarely begin with the obvious exploit. They begin with reconnaissance: LinkedIn, GitHub, leaked emails, forgotten subdomains, old VPN profiles, weak helpdesk workflows, contractor trust and sensitive documents moving through personal messengers. They then chain small weaknesses: a phishing pretext, OAuth consent, a reused password from an old breach, an exposed staging panel, an ownerless service account or an overly permissive cloud role. Each item may look low or medium severity in isolation, yet together they become a route to data, money or administrative control. Internal teams often see only fragments: one EDR alert, an unusual login, suspicious DNS, an employee report. Without a full adversary simulation, the organization does not know where the chain becomes critical or how long detection and escalation really take.

0trust0day runs Red Team work under clear rules of engagement: scope, prohibited actions, testing windows, emergency stop contacts and success criteria are agreed before execution. We build a threat model for your sector: fintech, e-commerce, SaaS, logistics, media or crypto. The team performs OSINT, maps external exposure, models initial access, validates identity controls, assesses lateral-movement opportunities and checks how events appear in EDR, SIEM, cloud logs and email telemetry. We do not break systems to prove a point; the objective is to prove risk safely and convert it into a defense plan. Every step is documented with artifacts: timestamps, requests, screenshots, logs, IOCs, ATT&CK techniques and affected controls. After execution, we run a working session with the Blue Team: which rules fired, where context was missing, which alerts were noise and which signals must be correlated. Deliverables include an executive summary, technical appendix, likelihood/impact matrix, 24-72 hour quick wins, 30-90 day remediation tasks, detection logic and retest criteria.

Case study: a European fintech platform engaged 0trust0day after its security team noticed targeted reconnaissance against compliance and finance employees. On paper the environment looked mature: SSO, MFA, endpoint EDR, SIEM and regular external scans. We began with OSINT and found that a design contractor had published portfolio screenshots of an internal interface, including role names and a partial URL structure. We also found a former employee email in an old breach corpus; that account still appeared in several SaaS groups. Under the agreed scenario, we created a phishing pretext impersonating the contractor without collecting real passwords or touching production data. The goal was to test request verification, OAuth-consent resistance and SOC response. After initial interaction, the team obtained limited test access to a non-critical workspace, demonstrated how excessive access could be requested through helpdesk and reproduced lateral movement only against pre-created control objects. EDR saw isolated signals, but SIEM did not connect OAuth activity, helpdesk behavior and atypical login into one incident chain. During the purple-team debrief, we tuned correlations, added rules for impossible travel, OAuth risk, dormant users and contractor access review. Detection time for the test chain dropped from several hours to 7 minutes, former accounts were removed, and contractor access moved to a separate owner-reviewed process.
