The Dilation Effect refers to the monitoring of users receiving fraudulent text messages from a sender named "Binance", resulting in financial losses. The content of the scam text message is to prompt the user to log in with a new device in another country, ask the user to call a certain phone number for consultation, and further induce the user to perform fund transfer operations. At present, it is understood that the users who received these text messages are all Hong Kong users. The Dilation Effect reminds users to handle SMS with caution, as SMS is a very ancient protocol with extremely poor security. Cannot use SMS as a trusted source. There are multiple possibilities for this. Firstly, there is an issue with Binance's official SMS channel; The second is that attackers use third-party SMS services (Amazon, Aliyun, etc.) to send SMS with a SenderID of "Binance"; Thirdly, counterfeit SMS messages were sent through custom SMPP protocol fields. https://www.
