My iPhone5 suddenly received a text message, then opened the message and flashed back, and the taskbar could not be pulled down. Is that virus information?

Please don't panic, this is just a loophole, not a virus. On August 30th, a remote denial of service vulnerability was discovered in Apple's ios and macOS systems. Sending Arabic strings as shown in the figure to the chat software or even SMS of ios or Mac users will cause the application to flash back and even the program to crash. ?

It is this string of code, which is a remote denial of service vulnerability. When the user receives this character string through chat software, e-mail, short message, Weibo, etc. , the program will flash back. At present, only ios6 and OSx 10.8 systems are affected by this vulnerability, and lower versions such as ios5 are not affected. This vulnerability has also been fixed in ios7 and osX 10.9. The current communication channels of this vulnerability are WeChat, friends circle, qq space, qq message, SMS (displaying the string trigger) and so on. , it will directly lead to related applications flashing back, unable to open, lost records and other consequences. Please don't try easily.
