Just because your company's Spam filter, virus filter and other defenses let an email through, doesn't mean it's harmless
Last year, one organization narrowly avoided a virus infestation. Alerts led them to the email in-boxes of the virus authors. To sneak in a virus, hackers used encrypted zip files, which went past filters because they couldn't be scanned. The organization caught it with the very last line of defense — desktop anti-virus software, which triggered after the users had plugged in the password to see the zip file contents! Had the bad guys written something new, instead of using off-the-shelf script kiddie code that was in standard pattern files, there could have been a major outbreak. Long Story Short: End-user awareness about email and attachments is every bit as important as anti-virus filters and firewalls. EVERY USER is an important part of hacker defense!
Do Not Reply and Send your Email Address
A common fraud, called "phishing" mostly used for spamming & etc, sends messages that appear to be from a computer or electronic company, bank, shop or auction, giving a promising promotion, offers and asking you to send and forward the email, copied to a fake email address. The fraudsters then use your email details to anything that you might regret in the future. Exposing your personal and corporate email addresses to these kind of fraud will result in exposing your information, your data, and your organization. These fake emails can be hard to spot, so no reputable organization will send a message requesting you to do spamming on their behalf just to receive freebies. Remember that any unsolicited emails are considered spam. Be careful when you forward and send an email, other Spam filtering devices might detect and tag you as Spam. EVERY USER has an important role and responsibility in securing their own personal and corporate email account!
