Firms should take extra care to protect their mailing lists from web-based direct attacks or hidden attacks through spam, an expert has suggested.

David Emm, senior regional researcher for Kaspersky Lab, advised firms who experience security attacks to enlist the help of professionals who will be able to secure their system.

He warned that shutting down their network from the internet may not necessarily be the best thing to do, as this could affect their business adversely.

“Taking down your internet is like a shopkeeper closing the shop sign: if you’re closed you’re not making money,” Mr Emm said.

“Make contact with tech support because they will have diagnostic tools to look at what’s going on and dig a bit deeper on the system and maybe even produce something for customer support or remediation with the company.”

A recent report by Symantec found that there has been a 100 per cent increase in the proportion of new malicious programmes between 2008 and 2009.
