ISLAMABAD: Pakistan’s telecom regulator said on Tuesday it blocked more than 1,300 websites, applications and social media pages involved in selling leaked data of Pakistani nationals.

The development follows a local broadcaster’s report that thousands of Pakistanis, including federal ministers and senior officials, were affected by a personal data breach, with the information now being offered for sale online.

The leaked data reportedly includes the addresses of mobile phone subscribers, call logs, copies of national identity cards and records of foreign travel. The breach appears to cover a wide range of individuals across different levels of government.

Only licensed telecom companies are responsible for storing and managing subscriber data, according to the Pakistan Telecommunication Authority (PTA).

"In its ongoing crackdown on unlawful content, PTA has blocked 1,372 sites, apps and social media pages involved in selling or sharing personal data," it said in a statement.
