Researchers Find Bluetooth Signals Can be Fingerprinted to Track Smartphones

Image
A new research undertaken by a group of academics from the University of California San Diego has revealed for the first time that Bluetooth signals can be fingerprinted to track smartphones (and therefore, individuals). The identification, at its core, hinges on imperfections in the Bluetooth chipset hardware introduced during the manufacturing process, resulting in a "unique physical-layer fingerprint." "To perform a physical-layer fingerprinting attack, the attacker must be equipped with a Software Defined Radio sniffer: a radio receiver capable of recording raw IQ radio signals," the researchers  said  in a  new paper   titled  "Evaluating Physical-Layer BLE Location Tracking Attacks on Mobile Devices. The  attack  is made possible due to the ubiquitous nature of Bluetooth Low Energy (BLE) beacons that are continuously transmitted by modern devices to enable crucial functions such as  contact tracing  during public health emergencies. The...

New Privacy Framework for IoT Devices Gives Users Control Over Data Sharing

Image
A newly designed privacy-sensitive architecture aims to enable developers to create smart home apps in a manner that addresses data sharing concerns and puts users in control over their personal information. Dubbed  Peekaboo  by researchers from Carnegie Mellon University, the  system  "leverages an in-home hub to pre-process and minimize outgoing data in a structured and enforceable manner before sending it to external cloud servers." Peekaboo operates on the principle of data minimization, which refers to the practice of limiting data collection to only what is required to fulfill a specific purpose. To achieve this the system requires developers to explicitly declare the relevant data collection behaviors in the form of a manifest file that's then fed into an in-home trusted hub to transmit sensitive data from smart home apps such as smart doorbells on a need-to-know basis. The hub not only functions as a mediator between raw data from IoT devices and the respecti...

Symbiote: A Stealthy Linux Malware Targeting Latin American Financial Sector

Image
Cybersecurity researchers have taken the wraps off what they call a "nearly-impossible-to-detect" Linux malware that could be weaponized to backdoor infected systems. Dubbed  Symbiote  by threat intelligence firms BlackBerry and Intezer, the stealthy malware is so named for its ability to conceal itself within running processes and network traffic and drain a victim's resources like a  parasite . The operators behind Symbiote are believed to have commenced development on the malware in November 2021, with the threat actor predominantly using it to target the financial sector in Latin America, including banks like Banco do Brasil and Caixa. "Symbiote's main objective is to capture credentials and to facilitate backdoor access to a victim's machine," researchers Joakim Kennedy and Ismael Valenzuela said in a  report  shared with The Hacker News. "What makes Symbiote different from other Linux malware is that it infects running processes rather than us...

New Emotet Variant Stealing Users' Credit Card Information from Google Chrome

Image
The notorious Emotet malware has turned to deploy a new module designed to siphon credit card information stored in the Chrome web browser. The credit card stealer, which exclusively singles out Chrome, has the ability to exfiltrate the collected information to different remote command-and-control (C2) servers, according to enterprise security company  Proofpoint , which observed the component on June 6. The development comes amid a  spike  in  Emotet   activity  since it was resurrected late last year following a 10-month-long hiatus in the wake of a law enforcement operation that  took down its attack infrastructure  in January 2021. Emotet, attributed to a threat actor known as TA542 (aka Mummy Spider or Gold Crestwood), is an advanced, self-propagating and modular trojan that's delivered via email campaigns and is used as a distributor for other payloads such as ransomware. As of April 2022, Emotet is still the most popular malware with a glob...
