Morpheus with Bitzi “anti-spoofing”

Morpheus, a popular filesharing client at version 4.5:

Includes free Bitzi anti-spoofing look-ups to download only the files you want.

That’s an accurate description (and has been true since at least Morpheus 4.1.1). If you see something you’re interested in downloading in search results, you’re a right-click away from a Bitzi lookup. If Bitzi users have judged the file to be spam, virus-laden, or corrupted, you’ll get a response similar to this:

bad file

Thirty Bitzi users have judged this file as dangerous or misleading (one bozo recommended the file). A few of the judgement notes tell the story:

Every time I write something,it will come up in my searching files. The size is 105,2 kb every time.


stupid spam, coming from….discuises itself under many wma files

If Bitzi users have judged the file you’re interested in to be worthy, you’d see something similar to this:

good file

That file happens to be the current release for Windows of Bitzi’s bitcollider file metadata collection tool.

Derek Slater notes that Bitzi metadata is itself subject to spoofing, and

even if Bitzi helps people sort out spoofs, the technological arms race will continue.

Very true. Bitzi is dependent upon community policing, and a concerted effort to create dangerous files and submit fraudulent judgements to Bitzi would work, at least for awhile. There are steps Bitzi can take to militate against such attacks should they become a problem. Unfortunately, as I noted recently, development proceeds at a bear in winter’s pace.

It should also be noted that Morpheus is just one of several applications that enable Bitzi lookups or submissions, though most of these send users to a Bitzi web page rather than integrating raw data from Bitzi lookups into their user interface as Morpheus has (see screenshots above).

  1. New Morpheus and Anti-Spoofing Tools

    I’m used to seeing huge ads for Movielink as well as MPAA anti-piracy statements in The Harvard Crimson .

  2. […] Morpheus with Bitzi “anti-spoofing” put this feature in the best possible light, highlighting a file that had been negatively rated by many Bitzi users. Most likely a very mall proportion of files that a user would encounter were rated at all, and invoking the feature would be a waste of time. […]
