The document discusses distributed denial of service (DDoS) attacks originating from the Caribbean region. It describes how attackers package malicious code into innocent-looking programs to create Trojan horses that turn users' systems into zombies controlled by bot herders. The bot herders then indirectly instruct the zombie networks to launch coordinated DDoS attacks on scheduled targets, as evidenced by activity maps showing attacks from Barbados to Trinidad and Tobago on specific dates.
