It is possible to hide threatening information by writing specific codes in digital communications, but this is a serious illegal and unethical behavior. Malicious use of codes to hide threatening information may involve cybercrime activities, such as online fraud, spreading malware, and implementing terrorist threats, which will cause great harm to individuals, organizations, and society, disrupt normal social order, undermine information security, and endanger the safety of life and property of others. Cyberspace has corresponding laws and regulations to regulate and combat such behavior, and law enforcement agencies have the professional ability to track and punish such malicious behavior. Any attempt to hide threatening information through improper means will be punished by law.
