Check for spam mails: Sometimes customers receive mail that looks similar to emails sent by one’s banks. However, before opening such mails it is essential to evaluate the sender, because sometimes these are spam emails that can infect the system with malicious software. Often this software can read keystrokes thereby sending important information like a password to AT&T Email IDs to unknown parties.
Check for phishing emails: These emails appear to be authentic emails sent from genuine IP addresses. However, these emails often ask the recipient to divulge details like ATM Pin number or bank details. Never share such information over the Internet.
