The Sauce: Mastery, OPSEC, and Fraud Prevention Vocabulary

Flashcards covering the technical, organizational, and philosophical terminology found in 'The Sauce' regarding operational security, fraud detection, and professional mastery.

Obsession

The intense, singular focus and discipline required to master a craft from scratch, described as the price paid to be undeniable and the catalyst for building a legacy.

Clean Hands

A principle of operational security (OPSEC) that involves keeping one's identity and location entirely separate from operations by using clean IP addresses, burner phones, and avoiding physical proximity to activity.

OPSEC (Operational Security)

A security and risk management process used to protect sensitive information and identity through compartmentalization and anonymity.

SOCKS5 Proxy

A type of internet proxy that routes specific application traffic through an intermediary server, often used to make a connection appear to originate from a residential line rather than a data center.

RDP (Remote Desktop Protocol)

A protocol that allows a user to control a computer in another location, effectively 'teleporting' an online presence to match a specific device fingerprint and locale.

Virtual Machine (VM)

An isolated computer environment running inside another computer, used in high-level OPSEC to ensure no personal files or traces can betray the user.

Fraud Risk Score

A numerical value from $0$ to $100$ assigned by merchant systems to judge a transaction; scores between $0-10$ are very low risk while $90+$ are typically auto-declined.

BIN (Bank Identification Number)

The first $6$ digits of a credit card that identify the issuing bank and card type, such as whether it is a business, platinum, or debit card.

AVS (Address Verification Service)

A system used to verify that the billing ZIP code or address provided during a transaction matches the information the bank has on file for the cardholder.

3-Dip Method

A technique where a user deliberately causes a chip read to fail three times in a row to force a terminal to fallback to magnetic stripe swipe mode.

Track 1

An alphanumeric magnetic stripe track that stores the cardholder's name, Primary Account Number (PAN), expiration date, and service code.

Track 2

A numeric-only magnetic stripe track that contains the card number, expiration date, service code, and encrypted discretionary data like CVV1.

Luhn Check

A checksum algorithm used to validate the accuracy of a primary account number (PAN) to ensure the card number is mathematically legitimate.

CVV1 vs. CVV2

CVV1 is verification data stored on the magnetic stripe for swiped transactions, whereas CVV2 is the printed $3$ or $4$ digit code used for card-not-present online purchases.

Sunk Cost Fallacy

An emotional bias where a person continues investing in a failing situation or relationship solely because of the time, money, or energy already spent on it.

Fullz

A dataset containing an individual's complete personal information, including Full Legal Name, Date of Birth (DOB), Social Security Number (SSN), and addresses.

Teslin

A synthetic printing paper favored for ID fabrication because its porous surface accepts ink and toner well and can be laminated to feel similar to genuine licenses.

Polycarbonate

A high-security, layered plastic used in modern IDs that is fused without adhesive and personalized using laser engraving to create tactile, raised text.

PearlEx

A brand of pearlescent pigments used by counterfeiters combined with screen printing to simulate the color-shifting appearance of holographic seals.

Lenticular Lens

A special lens structure embedded in high-security IDs used to create Changeable Laser Images (CLI) that display different data depending on the viewing angle.

Social Engineering

The psychological manipulation of people into performing actions or divulging confidential information by exploiting human emotions, needs, or trust.
