Malware 'grew by 100 percent' in 2007

The amount of malware detected on the internet doubled in 2007, according to the software security company F-Secure.

New malware variants are being created by cyber criminals "in bulk", according to F-Secure, which is based in Finland. Social engineering continued to be a favored way for cyber criminals to deliver malware, often conning email recipients into opening links that lead to web site hosting the malware.

Patrik Runald, security response manager at F-Secure, said: "We've never seen as many samples arrive at our lab."We would be unable to handle such huge loads if we would not have built a high degree of automation into our malware analysis systems over the past years." Online financial transactions are a favored target of cyber criminals, F-Secure warned, with the amount of phishing sites increasing exponentially.

So-called Man in the Browser attacks, where banking Trojans are fed directly into applications are also becoming more popular. For information on other digital products and services visit Broadband National.

Windows bug fixed by Microsoft

In its latest monthly patch release, Microsoft has patched a Windows bug that was deemed "critical" and has possibly been being exploited by cyber criminals.

The MS07-061 patch fixes an important flaw in Windows' Uniform Resource Identifier, which is involved in Windows' process for passing information between applications. Ben Greenbaum, a senior research manager at Symantec, told the Associated Press that the security flaw is "concerning". By taking advantage of the security flaw, cyber criminals could take over a victim's computer and steal crucial information such as passwords and financial information. Once infected, the victim's computer could also be used to disseminate spam.

This month unusually saw only two patches released, the other of which was deemed "important", the second-highest level of security rating for a patch. The second patch is for those with computers running the Windows 2000 Server and the Windows Server 2003.

Art.com hacked

The website operator Art.com, which sells art and posters, has been broken into by a hacker, the company has announced.

Credit card numbers and names of clients that used the company's sites between July and September this year were stolen. The company runs the websites Art.com and Allposters.com. Michael Heinstein, chief executive officer of Art.com, said: "We value our customers tremendously and understand how important security is to them.

"This is why we have acted to notify affected customers and credit card companies as quickly as possible after vigorously investigating this event." Art.com then swiftly took more action to make sure its sites were secured against "future attacks of this type", added Mr Heinstein. So far none of the credit card numbers that were stolen have been used in illegal transactions or for identity theft, Art.com stated.

Recently the website Bobbear, which combats money laundering was attacked by cyber criminals, according to the security software company Sophos. For more information on digital products and services visit www.dsldance.com

Cyber criminals 'take advantage of Halloween'

As Halloween draws nearer, cyber criminals have launched a campaign of spam emails related to the celebration, according to the software security company Sophos.

The most prevalent piece of spam is one that promises a gift card worth $250 in exchange for the personal details of the recipient. Among the information requested is email addresses, postal addresses, phone numbers and dates of birth.

Senior technology consultant for Sophos, Graham Cluley, said: "It's not immediately obvious whether this spam is being sent to commit identity theft or whether it's market research gone mad. "If you visit the site and give it your personal information the chances are that you will be bombarded with unwanted junk email until hell freezes over."

It is not likely that those behind the spam emails will really send out the promised gift card, Mr Cluley added. Meanwhile, the infamous storm worm is still as prevalent as ever, almost a year since it was first noticed, reports the Toronto Star.
