SurfControl's Australian content development team has identified the 650 percent increase, which is reflective of a global trend, SurfControl Australia managing director, Charles Heunemann, told ZDNet Australia.
During non-holiday periods 60 percent of junk e-mails are regurgitated around the Web and the 650 percent increase in indicative of new junk e-mail submissions to SurfControl's RiskFilter database - which categorises junk e-mail and blocks it from entering a customer's network.
"What's happening now is people are getting fun Christmas games but amongst them all are things like the Goner virus," Heunemann said.
"The consequences can be quite disastrous, especially for organistations with a lot of e-mail users with lots of addresses in their book...it can create quite an e-mail storm," he added.
Also, recipients of e-mail greetings, games, screensavers and movie files, often hoard them in their inbox, with one 5-megabyte holiday screensaver taking the same amount of space on a company server as 160 plain text e-mails, according to Heunemann.
"Holiday emails, such as the ever-circulating elf bowling game and a host of prank, joke and game messages, carry huge payloads that rob a company of valuable network resources and interfere with productivity," he said.
-The ongoing cost to organisations is quite high," Heunemann added.
