TCP data packet 9 on port 4244 from the victim&#39;s device contains cleartext information such as the device model and OS version, IMSI, and 20 bytes of udid in a binary format, which is located at offset 0x14 of this packet. Then, the attacker installs Viber on his device, initiates the registration process for any phone number, but doesn&#39;t enter a pin from SMS. Instead, he closes Viber. Next, the attacker rewrites his udid with the victim&#39;s udid, modifying the viber_udid file, which is located in the Viber preferences folder. (The udid is stored in a hexadecimal format.) Finally, the attacker starts Viber again and enters the pin from SMS.</p> <p>Viber through 11.7.0.5 allows a remote attacker who can capture a victim&#39;s internet traffic to steal their Viber account, because not all Viber protocol traffic is encrypted.
