Almost all Android-based smartphones are affected by a dangerous Android USSD vulnerability. The USSD vulnerability allows any malicious users to wipe completely your Android phone remotely, either by directing you to a URL, or through a text message or scan a QR code or NFC tag linking to the malicious website.
The USSD (Unstructured Supplementary Service Data) codes (a code starting with asterisk
*, continuing with hashtags
# or digits, which represent commands or data, and ending with a hashtag) are normally used by handsets to communicate with carriers. A common USSD code used by all handsets is
*#06# which displays the IMEI number of your device.
