A hacker collective calling itself Pokemongo that published what it claimed to be personal data of US FBI agents has followed up by breaching the American Advertising Federation.

The Pokemongo group published a 22,000-row CSV file containing names, email addresses, employers and other data relating to what appears to be several thousand AAF members spread across the US.
