I am doing security research on a jailbroken ios 11.4 using cycript. When attempting to attach to a process using cycript -p <pid>, I get a Killed: 9 error in the console.

Searching online seems to point to a code sign issue (https://www.securitylearn.net/tag/ios-killed-9/). However, I tried the steps, created my own self signed certificate in keychain and signed the binary but it still encountered the same error.

Has anyone encountered this before?
