A team of cybersecurity researchers has discovered a clever technique to remotely inject inaudible and invisible commands into voice-controlled devices — all just by shining a laser at the targeted device instead of using spoken words. Dubbed ' Light Commands ,' the hack relies on a vulnerability in MEMS microphones embedded in widely-used popular voice-controllable systems that unintentionally respond to light as if it were sound. According to experiments done by a team of researchers from Japanese and Michigan Universities, a remote attacker standing at a distance of several meters away from a device can covertly trigger the attack by simply modulating the amplitude of laser light to produce an acoustic pressure wave. "By modulating an electrical signal in the intensity of a light beam, attackers can trick microphones into producing electrical signals as if they are receiving genuine audio," the researchers said in their paper [ PDF ]. Doesn't this so...

Apple introduces a new privacy feature for all new MacBooks that "at some extent" will prevent hackers and malicious applications from eavesdropping on your conversations. Apple's custom T2 security chip in the latest MacBooks includes a new hardware feature that physically disconnects the MacBook's built-in microphone whenever the user closes the lid, the company revealed yesterday at its event at the Brooklyn Academy of Music in New York. Though the new T2 chip is already present in the 2018 MacBook Pro models launched earlier this year, this new feature got unveiled when Apple launched the new Retina MacBook Air and published a full security guide for T2 Chip yesterday. "This disconnect is implemented in hardware alone, and therefore prevents any software, even with root or kernel privileges in macOS, and even the software on the T2 chip, from engaging the microphone when the lid is closed," Apple explained in the guide [ PDF ]. The tech giant furt...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

In last 20 years, we have seen hundreds of caper/heist movies where spies or bank robbers hijack surveillance cameras of secure premises to either stop recording or set up an endless loop for covert operations without leaving any evidence. Whenever I see such scenes in a movie, I wonder and ask myself: Does this happen in real-life? Yes, it does, trust me—at least CIA agents are doing this. WikiLeaks has just unveiled another classified CIA project, dubbed ' Dumbo ,' which details how CIA agents hijack and manipulate webcams and microphones in Hollywood style "to gain and exploit physical access to target computers in CIA field operations." The Dumbo CIA project involves a USB thumb drive equipped with a Windows hacking tool that can identify installed webcams and microphones, either connected locally, wired or wirelessly via Bluetooth or Wi-Fi. Once identified, the Dumbo program allows the CIA agents to: Mute all microphones Disables all network ad...

Have you considered the possibility that someone could be watching you through your webcam? Or Listening to all your conversations through your laptop's microphone? Even a bit of thought about this probability could make you feel incredibly creepy. But most people think that they have a solution to these major issues i.e. simply covering their laptop's webcam and microphone with tape, just like Facebook CEO Mark Zuckerberg and FBI Director James Comey . But it's 2016, and a piece of tape won't help you, as a new experiment has proved that how easily hackers can turn your headphones into a microphone to spy on all your conversations in the background without your knowledge. A group of Israeli security researchers at Ben Gurion University have created a proof-of-concept code (malware) that converts typical headphones into microphones and then use them to record all your conversations in the room just like a fully-featured spying device.

Apple Mac Computers are considered to be much safer than Windows at keeping viruses and malware out of its environment, but that's simply not true anymore. It's not because Mac OS X is getting worse every day, but because hackers are getting smart and sophisticated these days. The bad news for Mac users is that malware targeting webcams and microphones has now come up for Mac laptops as well. Patrick Wardle, an ex-NSA staffer who heads up research at security intelligence firm Synack, discovered a way for Mac malware to tap into your live feeds from Mac's built-in webcam and microphone to locally record you even without detection. Wardle is the same researcher who has discovered a number of security weaknesses in Apple products, including ways to bypass the Gatekeeper protections in OS X. Wardle also released a free tool called RansomWhere? earlier this year that has generic detection capabilities for Mac OS X ransomware variants. Wardle is scheduled to present h...

A hidden microphone was found in Ecuador's embassy in London, where WikiLeaks founder Julian Assange is sheltering from extradition to Sweden, The Ecuadorean Foreign Minister Ricardo Patino claimed. The microphone was found in the office of the ambassador Ana Alban and was discovered last month during his visit to Britain to discuss issues surrounding Julian Assange. At a press conference in Quito, the foreign minister of Ecuador, held up a photo of a " spy microphone " that was found on June 14 inside a small white box that was placed in an electrical outlet behind a bookshelf. However, the purpose of the bug, according to Patino, was not to track the WikiLeaks founder directly, but rather listen to the conversations of ambassador Ana Alban. He told reporters: " We have reason to believe that the bugging was carried out by The Surveillance Group Limited, one of the largest private investigation and covert surveillance companies in the United Kin...
