Airscanner Mobile Security Advisory #08031201: Product: Platform: Requirements: Credits: Risk Level: Summary: Details: Record Spoofing: The FlexiSPY backend requires no authentication other than the IMEI of the infected phone. Since the record posted is done via an unencrypted HTTP POST, spoofed logs can be created and uploaded to the FlexiSPY backend. Flawed Encryption Scheme: The configuration information is stored locally on the infected device. The file is 'encrypted' to prevent a user from learning information, such as the phone number of the device permitted to connect to the infected phone and listen in on phone calls. Insecure Solution: The FlexiSPY product stores the location of the
backend in the settings file. Since the settings file can be decrypted
(and re-encrypted), it is trivial to change the location of the backend
to an alternate location. http://www.informit.com/articles/article.aspx?p=1185592 Workaround: Copyright (c) 2008 Airscanner Corp.
