PGP software pirated

[Hardeep Singh]

Hi All

Someone gave me a PGP signed message that unlocks the paid version of
PGP. Just to be sure it worked, I tried it and then uninstalled the
software (I dont use pirated stuff, GPG is much better for me).
However, does this mean that someone was able to find the private key
for the key PGP uses to sign licenses? If that could be found, then
probably our keys can also be cracked. While I personally find this
impossible, I want to know how the hackers were able to  give me a
signed message? Is it possible they tweaked PGP to use their private
key instead of PGPs and hence PGP is not really broken?
