When Does Software Start Becoming Malware?

Summary: Cisco Talos analyzed the "Infinity Popup Toolkit," software delivered via a Flash SWF file that bypasses Google Chrome's pop-up blocker to serve pop-up ads, and is in use by several advertisers on hundreds of sites. The toolkit uses clickjacking and a transparent full-window Flash object to hijack user clicks, decrypts an RC4 binary blob at runtime, and can send a beacon back to the advertiser when ad blocking is detected.

Why it matters: Talos draws the line at software that bypasses a security or privacy control or that a user did not ask to run, and this toolkit is already running on hundreds of sites while evading both Chrome's pop-up blocker and ad-blocking tools.
