It has been reported that the SMS feature on the iPhone has a serious security vulnerability, which may cause hacker attacks. According to Pod2g, the vulnerability originated from the user data header file (UDH) on the SMS function of iOS ). This file contains multiple advanced functions, one of which is to change the reply address of the text message. For example, when a user uses the iPhone to send a text message, the hacker uses this function, this causes the recipient to send a text message to other non-target users.
Apple issued a statement through Engadget to respond to the incident:
"Apple has always attached great importance to security issues. When a user uses the iMessage instead of the common text message (SMS) service, the confirmed email address can prevent this spoofing attack. However, one of the limitations of the common text message service is that it can send information with forged addresses to any mobile phone, So we strongly urge: if users are directed to an unknown website or address through text messages, be especially careful."
Apple's response seems to be a kind of avoidance, giving people the feeling that they fully shirk their responsibilities at the technical level.
Users should be reminded that they should be cautious with common text messages and be more careful when using text messages. Although you can process your bank information through many different channels these days-short messages are a taboo.
