Where we were the focus

Pentester by craft.
Not by certificate.

Since 2007. No hacking course — I watched my first bank get breached and realized the problem wasn't technical, it was about people.

Eighteen years on, the same obsession: find the door before the criminal does. I've operated inside Latin America's largest public bank, on Open Banking platforms, in private banking across Brazil, Portugal, Italy and Morocco, at the world's largest iGaming company and on Europe's payments backbone.

In parallel, I've supported the Federal Police and Civil Police on complex cyber casework, and spoken at the Florida Association of Private Investigators on phishing and web attack tradecraft.

The focus is the same wherever the engagement: where it hurts most, where the adversary is most sophisticated, where the margin for error is zero.

Eight sectors. One discipline.

Financial sector dominates the engagement count, but the craft is the same across every regulated, high-stakes environment. Where the data has consequence, I've operated.

/01 Banking & finance Public and private banks, Pix, Open Finance, Open Insurance, FAPI 1.0/2.0, brokerages.
/02 Government & security Federal Police, Civil Police, treasury, regulators. Casework + offensive assessment.
/03 Media & communications National press outlets, broadcast networks, publishing platforms. Newsroom-grade pressure.
/04 Healthcare Hospitals, Santa Casa, regulated institutions. LGPD/GDPR-bound patient data.
/05 Critical infrastructure Payments backbone, telecom, identity providers. Failure = systemic, not local.
/06 iGaming & payments Global iGaming platforms. Highest-scale fraud surface in private tech.
/07 Industry & manufacturing Automotive, atacadista, manufacturing OT/IT crossover environments.
/08 Sports & global events Olympics, Formula 1, federations. Short window, zero tolerance for failure.

Where I helped identify the gaps.

The hackers aren't slowing down.

Real-time ransomware victim disclosures from ransomware.live for the United States.

  • Loading latest disclosures…

Disclaimer. I'm not responsible for this list. ransomware.live aggregates public claims posted by attackers on leak sites and forums. The information may or may not be true — sometimes attackers exaggerate, sometimes victims haven't confirmed publicly. Treat as situational awareness, not as legal record.

Nine field defenses your IT team didn't put in the deck.

Tactical, current, opinionated. Picked from real engagements — not a 2018 Slideshare. iOS · Android · both.

/01BOTH

Lock your eSIM transfer

Carriers have been social-engineered into transferring numbers to attackers. Set a transfer PIN with your carrier. Without it, your phone is one phone call away from belonging to someone else.

/02iOS

Turn on Stolen Device Protection

iOS 17.3+. Forces Face ID for sensitive changes even at "trusted" locations. Defeats the stolen-phone-plus-shoulder-surfed-PIN attack that drains accounts in 90 seconds.

/03BOTH

Drop SMS for 2FA

SMS rides on SS7 — designed in the 80s, still trivially intercepted by anyone with telco access. Use TOTP (Aegis, Raivo, 2FAS) or, better, passkeys.

/04iOS

Disable USB while locked

Settings → Face ID & Passcode → USB Accessories OFF. Blocks forensic extraction tools (Cellebrite, GrayKey) when the phone is plugged in while locked.

/05Android

Audit Accessibility services

Malware lives in Accessibility. Once granted, it reads every screen, types every key, dismisses every prompt. Settings → Accessibility → review monthly. Revoke anything you don't recognize.

/06iOS

iMessage Contact Key Verification

iOS 17.2+. Detects when a contact was MITM-replaced server-side. Critical for executives, lawyers, journalists. Off by default — turn it on with anyone you trade sensitive data with.

/07BOTH

Forget unused Wi-Fi networks

Phones broadcast probe requests for every network they remember. Karma-style attackers spoof "linksys" or "Starbucks Wi-Fi" and your phone joins silently. Forget what you don't use.

/08BOTH

Switch to passkeys, not passwords

FIDO2/WebAuthn. Private key lives in the secure enclave, never transmitted. Phishing-immune by design. Apple, Google, Microsoft and major banks support them — start with the bank.

/09BOTH

Carry a charge-only cable

Public USB ports = juice-jacking surface. Airports, hotels, conferences. A €4 USB data-block adapter or a charge-only cable kills the attack. Use one whenever you're not at home.
