I wouldn't underestimate hackers and nearly any security method might eventually be defeated, but Trimark is encrypted in the music and the serial number is replicated if the song is replicated:
" 1) The technology will embed a unique serial number into each song
2) If the song is replicated, the serial will be replicated
3) The number and purchaser's identification will forward to a database repository
4) The technology will tag songs, leaving a traceable path to the purchaser with a patent pending audio-sniffer
5) Serial numbers will embed into all radio promotional media. Therefore, the technology can find radio piracy violators as well
6) The database scans serials without human intervention. If a piracy violation occurs, a notification will alert the subscriber, plus law officials capable of prosecution
7) Due to complex algorithms, encoding, and multiple random generated embedding, reverse engineering or "stripping" a serial will be next to impossible "
This sounds like it would be mighty difficult to defeat. Even security methods that can occasionally be hacked are utilized by the recording industry because most people can't hack them.
