    Alternate Data Streams - is HFS vulnerable too?

    I've been reading a lot about ADS as of late, but I haven't found an answer to this question: Is ADS a vulnerability of HFS as well? Supposedly NTFS uses a rip off of HFS's forking which leaves NTFS vulnerable to ADS attacks, but what about HFS? Is this a problem too?

    Wow, a question about the ancient Hierarchical File System (HFS). Are you referring to the original UNIX version, Macintosh, OS/2, DOS or WinNT? To date, no file (data) streaming vulnerabilities are known to exist in the *original* (UNIX) implementation. The problem with NTFS file streaming is not directly related to the original design of HFS, rather, the bastardized implementation that Microsoft cooked up based on how HFS forking operates.

    Ah, thank you. I was under the impression that MacOSX is run on HFS..

    It does afaik. But it is journalled.

    Fresh on the heels of its "Jaguar" release of Mac OS X 10.2, Apple Computer Inc. is about to spring a new surprise for the Unix-based OS: A journaled file system designed to provide corporate Mac sites with a new, historical view of their data.
