Protect your Business Data with an Anti Spam filtering Mechanism
Filed Under: Small Business

I remembered receiving an email sometime in June 2000 from one of my staff with a subject heading, “I love you” and an attachment text entitled, “love letter for you.” I was, of course, surprised and at the same time elated. Wow! I have a secret admirer (lover lol) from one my pretty staff. Little did I know that the email was not actually sent by her. I clicked on the attachment to read the ‘letter’ but there was none. Instead, funny things happened afterwards. My MIS staff reported that our mail server was infected by the ‘love bug.’

The ‘love bug’ or ‘I love you virus’ is actually a worm encrypted as VBS script attached to emails.

“Its massive spread moved westward as workers arrived at their offices and encountered messages generated by people from the East. Because the virus used mailing lists as its source of targets, the messages often appeared to come from an acquaintance and so might be considered "safe", providing further incentive to open them. All it took was a few users at each site to access the VBS attachment to generate the thousands and thousands of e-mails that would cripple e-mail systems under their weight, not to mention overwrite thousands of files on workstations and accessible servers.” (Source: Wikipedia)

It wrought a damage amounting to $5.5 approximately, before an anti-virus was developed to counter it.

If your network or system does not have an Anti Spam Filtering mechanism, you are making your business data vulnerable to possible malicious access and attacks like what the ‘love bug’ did in 2000. Stop threats before they reach your network with a Barracuda Spam Firewall. Enterprise class protection is now affordable to the small medium sized businesses like yours.

• Nothing to purchase, install, manage or maintain
• Your email passes through our filters before reaching your network
• Powered by Hosted Barracuda , a worldwide leader in email and web security

Email has now become the standard tool for business communication and therefore you have the responsibility to protect yourself and your business associated from any possible threats. Threats over the net will always be there. A simple spam mail is no longer simply an added memory grabber in your inbox, it could be a malicious script that is ready do harm on your sensitive files, which could mean unnecessary losses and/ or cost on your part. By all means, make that small investment and protect your business."

I am trying to find out just how much damage was done to this enterprise with this one Virus. I have never understood the thinking processes that go behind creating something so damaging and negative as a virus.
