Privacy by Defualt
Major threats that Mobile Crypto can handle & avoid:
Any remote and local Spy Phones software
Remote interception by: Active GSM (A51 and A52 Decipher)
Remote interception by: Passive GSM (A51 and A52 Decipher)
Remote interception by: Active 3G and 4G interception
Interception at the Cellular Operator based on 3G and 2G
Remote microphone interception
Remote fake apps installation or update
Prevent SS7 manipulation – including Mobile location via Mobile Operators via HLR
Prevent any leak of information via “ Usb Cable “that can be connected to any PC
Additional Features:
LTE-only mode - to reduce cellular radio attack surface by disabling enormous amounts of both legacy code
(2G, 3G) and bleeding edge code (5G).
Wi-Fi privacy - We supports per-connection MAC randomization and enables it by default. This is a more private approach than the standard persistent per-network random MAC used by modern Android.
Closed device identifier leaks - fixes several prominent device identifier leaks bypassing Android’s intention of apps not being able to uniquely identify a device such as the serial number, MAC addresses, IMEIs/MEIDs, SIM card serial numbers and subscriber IDs
Longer passwords by default - 64 characters instead of 16 characters. This avoids the need to use a device manager to enable this functional
Fingerprint unlock feature - by only permitting 5 total attempts rather than implementing a 30 second delay between every 5 failed attempts with a total of 20 attempts. This doesn’t just reduce the number of potential attempts but also makes it easy to disable fingerprint unlock by intentionally failing to unlock 5 times with a different finger.
PIN scrambling - to raise the difficulty of figuring out the PIN being entered by a user either due to physical proximity or a side channel.
