On 18 July 2013, Truecaller issued a statement on its blog stating that their website was indeed hacked, but claiming that the attack did not disclose any passwords or credit card information.

The group claimed on its Twitter handle to have recovered 459 GBs of database, primarily due to an older version of Word Press installation on the servers.

Truecaller provides a web enabled caller ID for your smartphones like iPhone, Android, Windows Phone and much more devices. This app gives full detailed of received call and messages from an unknown person.

Truecaller gets permissions to track your precise location so that people near you can search and access your details much more easily.
