FASTag is a toll collection system in India based on Radio Frequency Identification (RFID) technology. FASTag directly makes payments from the bank account to the toll plaza without stopping for transactions.

Cyble Research Labs found a publicly exposed website containing plain text data of an unidentified toll plaza. The exposed website has information related to transactions, vehicle registration, vehicle type, tag ID, digital signature, etc., used for transactions.

Figure 1 shows the website containing the configuration data of the website.
