ABSTRACT:
Methods and apparatus for attacking a screening algorithm. The methods include the steps of marking content to be downloaded, inserting at least one section of legitimate content into the marked content, and subjecting the content to a screening algorithm. The screening algorithm may include the steps of determining a number of segments that are included within the content, selecting at least two segments within the content, screening the two segments to determine whether the two segments verify correctly through the screening algorithm, and downloading the content when it is determined that the two segments verify correctly through the screening algorithm. Once the content has been successfully downloaded, the integrity of the downloaded content may be restored by removing the legitimate content that was previously inserted into the downloaded content.
