A leaked arsenal of hacking tools allegedly belonging to the National Security Agency (NSA) shows the US spy agency infiltrated the servers of a major Pakistani cellular service provider.
The data dump, publicly released by the ShadowBrokers hacking group earlier this week, includes alleged digital weapons and notes shared by NSA operators about their access inside the servers of a Pakistani mobile network.
Notes contained in the massive dump of encrypted data, which is still being analysed by network security researchers, include details of how NSA used the exploits to infiltrate cellular operators in Pakistan.
One snippet from the leak, several terabytes in size, includes at least 14 lines mentioning different servers operated by a major Pakistani cellular network.
The snippet, analysed by a security researcher who goes by the name X0rz, appears to show NSA operators sharing a step-by-step technical guide on how to hack into the servers.
“Try one of the following…old way, may not work on new machines,” says one section of the snippet.
Another section appears to show methods to retrieve call logs of users of the Pakistani cellular service.
“If searching for LACs and cell id’s, use the format in the documentation…if searching for phone numbers, use the normal format,” it says.
In a tweet, Wikileaks claimed the leaked “NSA cyber weapons variants” includes “code showing hacking of Pakistan mobile system”.
The data dump was publicly released earlier this week by the ShadowBrokers hacking group after it failed to auction the arsenal of hacking tools.
In a lengthy anonymous blog post, the group claimed it was releasing the files as a “form of protest” after losing faith in the leadership of US President Donald Trump.
ShadowBrokers had announced the auction for the alleged NSA cyber weapons made in August last year.
The authenticity of the code being NSA software was later confirmed by the documents provided by whistleblower Edward Snowden to the Intercept.
The exploits are “part of a powerful constellation of tools used to covertly infect computers worldwide”, said the Intercept, whose editors include journalists that worked with Snowden to publicise his notorious 2013 NSA leak revealing the extent of government snooping on private data.
It is unclear when the tools were used or how many Pakistani cellular networks were infiltrated, as security researchers are still analysing the massive trove of leaked data over terabytes in size.
