Be vigilant to defeat spam risk; InsideView.

Byline: Ian Callens

AS much as 97 per cent of all e-mails sent over the Internet are unwanted and unsolicited, according to research.

Some of these e-mails come from cyber-criminals and contain malicious attachments masquerading as Microsoft Office documents and PDFs.

One cyber-criminal community which had hijacked an internet service provider was taken out of action towards the end of last year. This meant levels of spam had stopped increasing; however, it is only a matter of time before we see a return to those levels.

So how can SMEs in the Midlands prevent themselves from falling foul of this spam threat? It is vital to keep operating systems, web browsers and applications up to date. This can be easily done through regularly running updates on all company computers and the main servers.

This will not only safeguard data, but limit the impact of an employee unwittingly opening a malicious attachment.

If a business does not utilise the latest web browser updates, the negative impact can be high.

Crafty 'spammers' exploit the familiarity of Microsoft Office attachments and PDF files to make targeted attacks on businesses and individuals, but the axe has also fallen on many unsuspecting employees.
