Phone hacking refers to the practice of intercepting or accessing someone else's phone messages, usually through the use of electronic devices and software. It is typically done without the knowledge or permission of the person being targeted, often for malicious purposes such as stealing personal information, financial data, or other sensitive details. Phone hacking has been in the news recently due to high-profile cases involving journalists who used this technique to gain access to private phone messages belonging to celebrities and public figures. This practice is considered a serious breach of privacy and can result in legal consequences for those found guilty of engaging in it.
