What information should you never share online?

Sharing your personal identifying information, such as your Social Security number, online can lead to serious privacy and security risks. This type of information is highly sensitive and can be exploited by cybercriminals for identity theft or fraud. When such details are disclosed, it becomes easier for malicious actors to impersonate you, gain unauthorized access to your accounts, or open new accounts in your name without your consent.

In contrast, while some information like your favorite websites, hobbies, and interests are generally less sensitive and can enhance social interactions online, they do not carry the same level of risk. Similarly, sharing friends' contact numbers may not be advisable due to privacy concerns, but it does not pose the same direct threat as revealing your Social Security number does. Thus, always prioritizing the protection of personal identifying information is crucial in maintaining your security online.
