Latest Trends in Spamming
in Hong Kong
With advancements in technology,
it is increasingly difficult to fight cunning spammers.

Spamming with WhatsApp Messenger
• Design of WhatsApp Messenger – can add members to chat groups without consent
• “Hit and run” strategy – spammer forms a chat group from block of “sequential” phone numbers, sends CEM to group members and quits the group
• Difficult to investigate – used pre-paid SIM cards to register for WhatsApp account; used VoIP phone number for customer communication
• Alerted WhatsApp Inc. – breach of terms of service
