Cross-browser Worm Spreads via Facebook, Security Experts Warn
By: Lucian Constantin, PC World
Malware writers have used Crossrider, a cross-browser extension
development framework, to build a click-fraud worm that spreads on
Facebook, security researchers from antivirus firm Kaspersky Lab said on
implements a unified API (application programming interface) for
building Mozilla Firefox, Google Chrome and Internet Explorer
The API allows developers to write code that will run
inside different browsers and, by extension, on different OSes. The
framework is still in beta testing and its creators plan on adding
support for Safari soon.
"It is quite rare to analyze a malicious
file written in the form of a cross-platform browser plugin. It is,
however, even rarer to come across plugins created using cross-browser
engines," said Kaspersky Lab malware expert Sergey Golovanov in a blog post on Monday.
