小心不要送给妈妈一个电脑病毒
Careful you don't send your mom a computer virus
Sites that offer free greeting cards can open up your PC to spam, spyware and other malicious bugs
That loving e-card you send to Mom this weekend could leave your computer loaded with spam, spyware and even viruses.
Even worse, it could do the same to Mom's computer, transforming your heartfelt Mother's Day greeting into a techno nightmare.
That's the warning from McAfee SiteAdvisor, a division of the system and network security company McAfee Inc. that tested online greeting card sites and found many delivered undesirable consequences along with the greeting.
The worst offender -- funnyreign.com -- resulted in an average of 1,075 pieces of spam per week landing in the card sender's inbox.
Two of the sites delivered Trojans downloaders, paving the way for viruses and other computer chicanery.
And while Shane Keats, market strategist for McAfee's SiteAdvisor, said the e-card testing monitored the effect on the sender's inbox, he said it is likely Mom would find her inbox inundated as well.
"The bad guys go where the users are because that's where the money is," said Keats. "Mother's Day, as I understand it from the Greeting Card Association, is the third most popular card holiday and that goes for e-cards as well."
That makes this Sunday's Mother's Day a bonanza for spammers and scam artists who are hoping to cash in on the million of e-cards expected to be sent this week -- not by collecting a fee for the cards but by collecting something that can be far more lucrative -- the e-mail addresses of the senders and the recipients.
"What we're finding more and more these days is that there is less hackers writing viruses to get famous, they are writing them to enrich themselves," said Keats. "The trend we are seeing is economically motivated hacking."
Keats said the aim is to get as many pieces of spyware on to computers as possible.
The McAfee SiteAdvisor crawls the World Wide Web, clicking 'yes,' to everything it finds on websites. It takes those findings and tests what happens to a computer when it gives the okay to websites.
Keats said in the case of the spam tests, each site is given a unique e-mail address, so that all incoming mail to that address would be a result of that signup.
"We track what happens to the inbox and if we start to see spam or commercial e-mail, we know it could only be because of that signup," he said. "We have done that on a massive scale."
McAfee's spam tests have covered about 95 per cent of trafficked websites, according to Keats. For the Mother's Day test, McAfee entered a variety of search terms, such as Mother's Day card and other to come up with a list of e-card sites which it tracked for violations of privacy and other security breaches.
According to McAfee's SiteAdvisor, a Google search for "mother's day card" yielded two sites that earned McAfee's red rating -- meaning the site is considered dangerous -- on the first page of results.
Clicking randomly on the page would send the user to an unsafe site 10 per cent of the time, the SiteAdvisor warned. Keats said there are safe alternatives to the high-risk sites and the SiteAdvisor came up with four that passed.
