Mexico is one of the biggest buyers of next-generation surveillance technology. And now data leaked to Forbes indicates it's taken an unprecedented step in becoming the first-known buyer of surveillance technology that silently spies on calls, text messages and locations of any mobile phone user, via a long-vulnerable portion of global telecoms networks known as Signalling System No. 7 (SS7).
The revelation was contained in what an anonymous source close claimed was internal sales information…

The whistleblower said they were unable to find any legitimate reason for the high volume of the requests for location information. “There is no other explanation, no other technical reason to do this. Saudi Arabia is weaponising mobile technologies,” the whistleblower claimed.
The data leaked by the whistleblower was also seen by telecommunications and security experts, who confirmed they too believed it was indicative of a surveillance campaign by Saudi Arabia.
The data shows requests for…

Bluetooth utilizes a device pairing mechanism based on elliptic-curve Diffie-Hellman (ECDH) key exchange to allow encrypted communication between devices. The ECDH key pair consists of a private and a public key, and the public keys are exchanged to produce a shared pairing key. The devices must also agree on the elliptic curve parameters being used. Previous work on the "Invalid Curve Attack" showed that the ECDH parameters are not always validated before being used in computing the resulted…

“The BlueBorne attack vector requires no user interaction, is compatible to all software versions, and does not require any preconditions or configurations aside of the Bluetooth being active,” warned the researchers.
“Unlike the common misconception, Bluetooth enabled devices are constantly searching for incoming connections from any devices, and not only those they have been paired with,” they added.
“This means a Bluetooth connection can be established without pairing the devices at all.…

An engineering and computer science professor and his team from The Ohio State University discovered a design flaw in low-powered Bluetooth devices that leaves them susceptible to hacking.
Zhiqiang Lin, associate professor of computer science and engineering at the university, found the commonly used Bluetooth Low Energy devices, such as fitness trackers and smart speakers, are vulnerable when they communicate with their associated apps on the owner’s mobile phone.
"There is a fundamental…

On November 3rd, 2019, [...] a critical vulnerability affecting the Android Bluetooth subsystem [was reported]. This vulnerability has been assigned CVE-2020-0022 and was now patched in the latest security patch from February 2020. The security impact is as follows:
On Android 8.0 to 9.0, a remote attacker within proximity can silently execute arbitrary code with the privileges of the Bluetooth daemon as long as Bluetooth is enabled. No user interaction is required and only the Bluetooth MAC…

Researchers at the Center for IT-Security, Privacy and Accountability (CISPA) have identified a security vulnerability related to encryption on Bluetooth BR/EDR connections. The researchers identified that it is possible for an attacking device to interfere with the procedure used to set up encryption on a BR/EDR connection between two devices in such a way as to reduce the length of the encryption key used. In addition, since not all Bluetooth specifications mandate a minimum encryption key…
