In the announcement, Apple emphasized its commitment to user security and privacy, explaining that the move was "necessary" to deal with potential risks from Beeper Mini's iMessage interference features such as data disclosure, making it easy to become a target for attacks and fraud.

"We are taking action to protect our users by blocking credential phishing techniques. These techniques used to gain access to iMessage pose significant risks to user security and privacy," the company's official announcement read.

According to MacRumors , Beeper Mini works by intercepting the iMessage protocol, using Apple's push notification service to "convince" the server that the Android device with the software installed is actually an Apple-made device. "Apple" believes that this method is an act of "using fake authentication information" and poses a security risk to users of its device ecosystem.

Meanwhile, Beeper claims that the processing it uses does not compromise encryption or privacy, and its documentation also states that no one can read the content of messages except the sender/receiver. However, Apple cannot prove this and concludes that there is a risk.

Immediately after Apple's announcement, Beeper CEO Eric Migicovsky expressed his willingness to cooperate with the "bitten apple" to test and evaluate security issues in the programming of the Beeper Mini application. He emphasized the importance of securing the communication channel between iPhone and Android users, and pointed out the shortcomings of unencrypted SMS messages on multiple platforms. Despite Apple's stance, Eric stated that he would continue to look for solutions to help Beeper Mini or similar services continue to operate.
