Internet Explorer 8’s Smartscreen Filter has passed a new milestone, passing the one billionth stopped malware download.

“Socially engineering attacks like malware are a growing threat on the internet and are one of the most common risks to people’s safety online” wrote Microsoft’s James Pratt.

“We have got better and better at blocking malware through the SmartScreen Filter because we have continued to invest in our back end service since we released IE8 in March 2009” said Pratt.

In the last two months, more than 100 million malware attempts have been blocked by Internet Explorer 8, 5 times as many as the same time last year, with more than 1.7 times the users.

The continued investment and development of malware protection is great for consumers, and helps keep their home PC’s safe.

Malware, also known as phishing (pronounced fishing), protection can also be found in other popular browsers such as Firefox, Chrome, and Opera.

A new security vulnerability has been found in Apple Safari’s Autofill feature, which can allow malicious websites to extract users personal information from their Address Book.

“All a malicious website would have to do to surreptitiously extract Address Book card data from Safari is dynamically create form text fields with the aforementioned names, probably invisibly, and then simulate A-Z keystroke events using JavaScript. When data is populated, that is AutoFill’ed, it can be accessed and sent to the attacker” wrote security researcher, Jeremiah Grossman.

Grossman submitted the vulnerability to Apple on 17th June, but Apple is yet to comment on the issue. Grossman has also released proof-of-concept code illustrating how the vulnerability works.

The vulnerability affects both Safari 4 and Safari 5 on Mac computers, with no patch in sight from Apple.
