• Where necessary I refactored code to improve the overall quality

Further comments

IMSI and IMEI cannot be distinguished from each other in certain situations. When a 15 digit number with no other characters is detected it will prioritize setting it as an IMSI. A separate update in the OpenCTI project would be needed to allow users to edit the observable type while in draft mode.
