Microsoft PlayReady – complete client identity compromise
Posted by Security Explorations on May 09
Hello All,
We have come up with two attack scenarios that make it possible to
extract private ECC keys used by a PlayReady client (Windows SW DRM
scenario) for the communication with a license server and identity
purposes.
More specifically, we successfully demonstrated the extraction of the
following keys:
– private signing key used to digitally sign license requests issued
by PlayReady client,
– private encryption key used to decrypt license…
