Viaccess 2
Viaccess 2 is the name given to two Viaccess systems developed by the France Telecom subsidiary, Viaccess. The first system often referred to as Viaccess 2 is Viaccess PC2.4. Viaccess PC2.4 is an insecure system which can be beaten with software-modified receivers allowing unauthorized viewers to watch premium content without paying any fees.
The second system often referred to as Viaccess 2 is Viaccess PC2.5. In contrast to Viaccess PC2.4 (or its predecessor Viaccess PC2.3), Viaccess PC2.5 has not been publicly broken and remains a secure system since it was launched.
