FileNuke app in wet fizzle claimBy Chris Williams. Published: 2nd Oct 2005, 17:37:56 | Permalink | Printable
BPUT doesn't quite cut it, say fellow codersConcerns have been raised over the effectiveness of Paul Vigay's evidence destroying software, FileNuke. The program claims it offers "military grade" removal of information from magnetic media, so that there is "no chance of data recovery, even by the most hardened forensic scientists."
The software works by repeatedly overwriting a file with random and predefined data. In theory, experts will then be unable to scan the magnetic media for the original file if the disc was ever seized or stolen. However, as pointed out by a few fellow coders, the RISC OS filesystem tends to move the position of files around the surface of the disc when the files are extended in size or the filesystem is reorganised. This means fragments of files tend to be scattered around the disc.
According to the BASIC source code distributed with FileNuke, the application only removes a given file from its current position on the disc, and does not remove partial fragments potentially littered around the disc. This means aforementioned forensic scientists could recreate a supposedly destroyed file.
One programmer whispered, "I applaud anyone developing for our market and don't like stomping on anyone's efforts, but I'm concerned that this is misleading people into a false sense of security and is being falsely promoted."
