# Apple iCloud Desktop Client v5.2.1.0 is vulnerable to local credentials disclosure after the user is logged out.

# It seems that iCloud does not store the supplied credentials while the user is logged in, but after sign out the supplied username and password are stored in a plaintext format in memory process.

# Funny eh?!

# A potential attacker could reveal the supplied username and password in order to gain access to iCloud account.

# Authors are not responsible for any misuse or demage which caused by use of this script code.

# Please use responsibly.
