Cybercriminals are doing big business in the gaming chat app Discord

CBS News found more than three dozen groups that cybercriminals call "money servers" on Discord.

Cybercriminals have set up shop on Discord, a popular chat application for gamers with more than 250 million active users. Hackers have modified many of the app's private groups to function like retail shops that sell illicit products, including stolen credit card numbers, cracked customer accounts for Delta Air Lines and Hilton Hotels, as well as malware that can be used to infect computer networks.
