Banks, social networks new target for computer viruses

Cyber criminals are increasingly focusing their attacks on the hundreds of millions of users of social networks and on loopholes in bank security systems, security software vendors said on Wednesday. At the same time, spam e-mail messages rose sharply in the third quarter, Symantec Corp said.

And as Facebook reached 300 million accounts in September, social networks and social media continued to attract criminals, smaller research firm F-Secure said in its quarterly virus report. "As Twitter has grown in popularity, it has been increasingly targeted by worms, spam and account hijacking," F-Secure said.

Cyber criminals choose targets that are widely used, allowing them to go after the largest number of potential victims. "Cyber criminals continue to follow the money," said Yuval Ben-Itzhak, technology chief at a small security software vendor Finjan, who on Wednesday revealed a new method criminals use to steal money from bank accounts and hide their tracks.

Finjan said it expects a growing trend of using new software that forges on-screen bank statements, concealing the true transaction amount to dupe account holders and their banks, and then sends the stolen money to money mules accounts.

"With the combination of using sophisticated Trojans for the theft and money mules to transfer stolen money to their accounts, they minimize their chances of being detected," Ben-Itzhak said.

The amount of spam in all e-mail traffic rose to 88.1 percent in the third quarter from 81 percent a year ago, said Symantec's MessageLabs in its quarterly report. MessageLabs said botnets are now responsible for sending 87.9 percent of all spam. Hackers take advantage of the PC vulnerability by booby- trapping websites with a malicious code that loads onto computers.

Infected PCs are commandeered into a botnet, a network of hijacked computers. They are used for identity theft, spamming and other cyber crimes. "Over the past year, we have seen a number of ISP's (Internet service providers) taken offline for hosting botnet activity resulting in a case of sink or swim and an ensuing shift in botnet power," MessageLabs analyst Paul Wood said in a statement.

"However, this won't always be the case as botnet technology has also evolved since the end of 2008 and the most recent ISP closures now have less of an impact on resulting activity as downtime now only lasts a few hours rather than weeks or months as before," Wood said.

Is Nokia likely to enter laptop industry?

The world's top cellphone maker Nokia is eyeing entering the laptop business, its Chief Executive Olli-Pekka Kallasvuo said in an interview to Finnish national broadcaster YLE on Wednesday.

"We are looking very actively also at this opportunity," Kallasvuo said, when asked whether Nokia plans to make laptops.

Industry has rumoured about Nokia's possible plan to enter the PC industry since late last year, but Kallasvuo's comment was the first official admittance of such plans.

"We don't have to look even for five years from now to see that what we know as a cellphone and what we know as a PC are in many ways converging," Kallasvuo said.

"Today we have hundreds of millions of people who are having their first Internet experience on the phone. This is a good indication," he said.

Nokia's comments come a week after No 3 PC brand Acer launched a foray into the phone business with eight cellphone models, joining leader Hewlett-Packard and No. 4 Lenovo in the high-growth space.

While strong profit margins in the smartphone industry attract PC brands, the attraction of the low-margin computer industry is less obvious.

"Nokia maybe nervous about entering a market segment that is already heavily commoditised, but it would be in a position to exploit its enormous scale in manufacturing, supply chain and distribution," said Ben Wood, research director at CCS Insight.

"All leading mobile network operators and retailers are adding connected notebooks and netbooks to their portfolios alongside mobile phones. On this basis it comes as no surprise that Nokia is evaluating this segment," he said.

The global PC industry was resilient for most of last year when other technology sectors were ailing, but it too has now been caught up in the deepening economic downturn that has hit demand from consumers and corporate buyers.
