Details of 44 Million Pakistani Mobile Users Leaked Online, Part of Bigger 115 Million Cache

An anonymous reader quotes a report from ZDNet: The details of 44 million Pakistani mobile subscribers have leaked online this week, ZDNet has learned. The leak comes after a hacker tried to sell a package containing 115 million Pakistani mobile user records last month for a price of $2.1 million in bitcoin. Data contains names, phone numbers, national IDs, and home addresses among others, and is believed to have originated from Jazz, a local mobile provider. According to our analysis of the leaked files, the data contained both personally-identifiable and telephony-related information. This includes the likes of: Customer full names; Home addresses (city, region, street name); National identification (CNIC) numbers; Mobile phone numbers; Landline numbers; and Dates of subscription.

Based on the dates of subscription, the oldest entries in the leaked files are from late 2013, suggesting that hackers either got their hands on an older backup file, or the breach took place in 2013, and only now surfaced online. The vast majority of entries in the leaked files contained mobile phone numbers belonging to Jazz (formerly Mobilink), a Pakistani mobile operator. However, ZDNet also identified phone numbers that appeared to belong to other mobile operators. [...] The incident is already under investigation in Pakistan, where the Pakistan Telecommunication Authority (PTA) and the Federal Investigation Agency (FIA) are looking into the matter since last month when the hacker first tried to sell the entire 115 million batch on a hacker forum.
