What should you always be cautious about when using email or chat?

Being cautious about opening attachments is paramount when using email or chat because attachments can be a common delivery method for malware, viruses, or phishing scams. Cybercriminals often disguise harmful files as innocuous documents or images, tricking users into downloading them. By opening an attachment without verifying the sender or the content, you may inadvertently compromise your device’s security and your personal information.

In contrast, while using emojis, replying quickly, or meeting new contacts may have some level of consideration for privacy or miscommunication, they do not pose the same level of immediate security threat that comes with opening attachments. Thus, the emphasis on exercising caution with attachments is critical for maintaining safe communication online.
