Ignore waving red flags? Pay the cost

Organizations can’t afford to be oblivious. Anti-fraud professionals are trained to be skeptical. They should teach their “trust but verify” skills to all in their spheres.

Teaming with anti-fraud pros of many stripes

Opportunistic fraudsters often have an advantage over CFEs: They can freely and spontaneously select co-conspirators by skill, position and corruptibility.

Their experience and techniques, when combined with ours, frequently produce extraordinary synergies that outfox versatile criminals.

The synthetic ID you can't see

Criminals are using a new form of fraud called credit privacy numbers (CPN) to defraud financial institutions and game credit bureaus.
