Security and privacy issuesEdit
On 17 July 2013, Truecaller servers were allegedly hacked into by the Syrian Electronic Army. The group claimed on its Twitter handle to have recovered 459 GBs of database, primarily due to an older version of WordPress installation on the servers. 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.
