When Does Software Start Becoming Malware?

New submitter Da w00t writes: Talos security researchers detected a malicious shockwave flash file that not only bypasses pop-up blockers, but also accurately fingerprints computers with the help of some JavaScript. The 'Infinity Popup Toolkit' is a prime example of software that falls into this gray area by bypassing browser pop-up blocking. In deciding to classify the toolkit as malware, the researchers pondered where the line lies between software that's harmful and software that's not. Quoting: "Without a clear standard defining what is and is not acceptable behavior, identifying malware is problematic. In many situations, users are confronted with software that exhibits undesirable behavior such as the Java installer including a default option to install the Ask.com toolbar. Even though many users objected to the inclusion of the Ask.com toolbar, Oracle only recently discontinued including it in Java downloads after Microsoft changed their definition of malware which then classified the Ask.com toolbar as malware."

non-isolated third-party cookies are data trojans

Toolbars are just the tip of the iceberg. All major browsers are malware because they don't isolate cookie storage (or all storage, really) between origin domains, breaking the same-origin policy. Third-party cookies then become data trojans. Intent is important here. It isn't just a vulnerability, but a design flaw continued by the fact that all major browser development is funded by advertising companies.
