| Can't Copy Protected CDs still be cracked?
You guys have probably heard about the new cipy protection for music now. When played in regular home stereo, the unrestricted tracks will be active. But, when played on a CD, the copy protected restrictive traks will be activated limiting the # of copies you can make.
Can't somebody play the CD in the stereo, record it to cassette, then rip the songs from the casette to the computer. Then maybe use software to clean up the sound then upload? |

It's always been possible to duplicate analogue recordings, but it hasn't been too big a deal for the industry, because the duplicates are always worse than the original, and people tended to actually buy things they liked. However, with digital recordings, you can make bit-perfect copies, and that's where the problem lies, in the eyes of the copyright holder.
Any time you pass digital audio through an analogue step, you reduce the quality. Especially cassette tape! "Cleaning up" can never restore the information you lost - the laws of physics are against you. |

I wouldn't worry about that problem just yet. I'm pretty sure there will be a way to copy music for a long time. Copy-Protection on cd's has been a lost cause so far...such as holding shift when you insert the cd.  |

I don’t think CD>Tape>PC will be a neccisary step by any stretch. This will not be then end of consumer converted media.
Why? Well – one of my favorites: If it can be engineered, it can be un-engineered. Some crafty hack will find a way to beat it, publish the findings, and we’re back at square one. Simply more money spent by the RIAA/MPAA in a useless fight.
Sorry for taking it OT.

Just speculating here as I haven't encountered a Copy Protected Cd as of yet.. but I wouldn't think you'd need to do the analog cassette route. Musicmatch (free recorder/player) offers a record in analog mode, I would think that this would defeat the digital copy protection with a minimal loss of quality. I'm certain that other ways to defeat this so called "protection" will become available soon if they aren't available already.
If they can create it simple logic tells you that it can be circumvented. |

Original poster seems to be referring to the new tech BMG is using, as reported here, for example : »www.reuters.com/newsArticle.jhtm···=8814566
It seems to be another variation of the trick where you're supposed to get the CD-audio on a standalone player, but only the Microsoft-format tracks on a computer-type drive.
In the past this type of scheme has relied on two things: the Windows autorun feature, and some sort of monkeying with the data structures on the disk to confuse the ripping software so it sees the compressed tracks and misses the CD-audio.
Auto-run is worse than a design defect; it is an anti-feature that constitutes a gaping security hole. At least one previous scheme of this kind actually installed a driver, without warning the user, and even if the user opted out of a subsequent prompt. The driver then would always ran silently in the background and disabled ripping if it detected a disk with a certain digital marker.
That's a perfect illustration of malware installation by the autorun exploit. Every Windows user should turn off autorun and be careful never to execute any software from what purports to be an audio CD. This is the only reason this thread qualifies for the security forum.
The other trick usually involves a falsified table of contents or some other violation of the CD specifications to make the CD-audio harder for the user to access. It can be overcome by ripping with suitable software (also optical drives differ in their behavior). Try Nero or EAC on Windows; isobuster on Windows; Grip on Linux. Reportedly the BMG tricks don't work on Mac. |

To get around any copy protection I thought you just need to create a ISO image of the original cd, and then burn the ISO image to a cd-r/rw. |

Yes they can, And in the Digital domain too, but i'm not saying how to do it !
I'm all for copy protection, whether it's Music/Films/Software whatever. And so would you be i imagine if you produced similar work.
Everybody likes to get paid for their work, and eat etc etc don't they ?

??? Like a previous poster said, you have to reply on the Windows Autorun feature to work in order to execute the copy protection. Holding shift while inserting the cd tells Windows not to autorun. |

??? That is SunnComm's Mediamax copy protection scheme. That
was cracked by a Princeton University student, IIRC, and
SunnComm fired off a C&D notice at him, claiming the loss
of $10 million over it. They backed down from their legal
threat after an overwhelming amount of negative publicity.
The latest scheme relies on autoplay being turned on to
install a hidden DRM driver that supposedly interferes
with CD ripping software. But it, like the previous ones,
won't load (and programs like CDex can just ignore the
data track) if it is turned off.
DRM and all forms of copy protection are snake oil. There
hasn't been one that hasn't gotten cracked yet. If it can
be heard or seen, it can be copied.

So true! Lets just say, I can copy any CD or DVD made*. I might have to copy the "Copy Protection" along with it... but I will have a copy of the original.

crikey spanner, no wonder you get the attention you do, fancy stirring the pot with a bl$%^y big wooden spoon,
good to see....only because if we don't see our own short falls, how can we get better
sorry mods, it is off topic, so ill get back to the question
the technology is only young, like most of what we play with, sure digital does give more control, for big brother, can i hear anyone crying over where did analog go...
but realistically looking at this question...
someone will break the security for anything that is produced to secure the CD, the problem still remains, that while we use technology at the rate we do...it is inevitable someone will pay to break its code, its human nature |

Aww, reminds me of the old days of Locksmith on the Apple II..
Anything can be cracked given the time, skills and motivation to do so.
Using an analog device to 'copy' a digital source is just silly imho.
