The protagonist received a text message while eating.

This is indeed a common fraud technique some time ago. In fact, judging from the nature of the case, this kind of fraud is not fraud in the legal sense, but theft. Their basic skills are:

1. Send short messages in groups through pseudo base stations or other commercial short message ports. The content is what you said in the title. Because of the large amount of messages sent, there will always be people who have just attended various parties recently who will believe it.

2. A website will be attached to the content of the short message, saying that you log in to this website to download pictures. In fact, this is a mobile phone Trojan virus link. Download it to your mobile phone, and the private information on your mobile phone will be stolen, such as the bank information you have logged in;

3. After Trojan steals your online banking, Alipay and other information, it will automatically upload it to the cheating paper server through the background, and the cheating paper will log in to your online banking or Alipay according to the obtained information, thus directly stealing your funds;

Precautionary principle:

1. If you are a network expert, it is a piece of cake to identify the authenticity of the website, then you can open it with confidence; If you don't know anything about websites and domain names, and don't know whether a website is true or not, don't click on the website in the short message at will;

2. The mobile phone must be equipped with security protection software, such as LBE, which can scan the mobile phone regularly, keep the protection function running at any time, and it is easy to find and stop Trojan horses.
