Researchers from the University of Illinois, Chicago said in a new paper that most browsers cache the images in a location that’s separate from the ones used to store site data, browsing history, and cookies.
Researchers develop a new technique that will keep your online photos safe from facial recognition algorithms.The research, which has been ongoing for more than six months, is targeted at countering the facial-recognition algorithms of big tech firms such as Facebook and Google.
They say it allows anyone with a laptop and less than a thousand dollars of equipment—just a telescope and a $400 electro-optical sensor—to listen in on any sounds in a room that's hundreds of feet away in real-time, simply by observing the minuscule vibrations those sounds create on the glass surface of a light bulb inside.
Social engineering is the practice of psychological techniques that are used on people with the intention of eliciting sensitive information from them in order to gain access to secure systems.Described below are some of the 5 most common social engineering techniques that attackers like to use.
Though Apple has been using differential privacy since 2017, it’s been combined with federated learning only as of iOS 13, which rolled out to the public in September of this year.
Alex Heid, chief research and development officer at SecurityScorecard, has developed a simple method for detecting whether an Airbnb host is watching guests live on a hidden camera.Here's how to find out if your Airbnb host is discreetly watching you on a live security camera.
A group of researchers from UC Santa Barbara has developed a new way to identify people behind the walls using off-the-shelf Wi-Fi transceivers and analyzing their walking gait.
The research team behind this exfiltration method says it tested the CTRL-ALT-LED technique with various optical capturing devices, such as a smartphone camera, a smartwatch's camera, security cameras, extreme sports cameras, and even high-grade optical/light sensors.
Their technique uses single-photon detectors combined with a unique computational imaging algorithm that achieves super-high-resolution images by knitting together the sparsest of data points. The big advantage of this kind of active imaging is that the photons reflected from the subject return to the detector within a specific time window that depends on the distance.
The email proves that Facebook has been aware for five years of a technique called “sniper-targeting” that bypasses its anonymity safeguards and enables customized ads to reach just a few or even a single person.
The data Google is turning over to law enforcement is so precise that one deputy police chief said it “shows the whole pattern of life.” It’s collected even when people aren’t making calls or using apps, which means it can be even more detailed than data generated by cell towers.
It's no surprise that law enforcement seeks help from tech companies during criminal investigations, but the use of location history databases like Sensorvault has raised concerns...
Often, Google employees said, the company responds to a single warrant with location information on dozens or hundreds of devices. After receiving a warrant, Google gathers location information from its database, Sensorvault, and sends it to investigators, with each device identified by an anonymous ID code.
"From the negative perspective, people can use our cross-browser tracking to violate users' privacy by providing customized ads," Yinzhi Cao, the lead researcher who is an assistant professor in the Computer Science and Engineering Department at Lehigh University, told Ars.
Firefox users will first need to visit the about:config page, enter " privacy.resistFingerprinting " in the search box, and toggle the browser's anti-fingerprinting features to " true ." Image: ZDNet Firefox's letterboxing support doesn't only work when resizing a browser window but also works when users are maximizing the browser window, or entering in fullscreen mode.
The practice is ongoing according to the sources, and court documents and an audio recording obtained by Motherboard also detail a previously prosecuted case in which one debt collector tricked T-Mobile by fabricating cases of child kidnapping to convince the telco to hand over location data.
While many people are enjoying the genealogical research aided by companies such as 23andMe, Ancestry.com , and MyHeritage, they are also unaware that law enforcement is using them as “genetic informants.” In fact, Family Tree DNA has been allowing the Federal Bureau of Investigation (FBI) to submit suspects’ DNA in order to investigate unsolved violent crimes.
"The people who are doing that are getting a lot of money and are doing that [full time]." Dubbed "AirHopper" by the researchers at Cyber Security Labs at Ben Gurion University , the proof-of-concept technique allows hackers and spies to surreptitiously siphon passwords and other data from an infected computer using radio signals generated and transmitted by the computer and received by a mobile phone.
It's thus not as serious as a remote attack technique that allows the execution of arbitrary code or exposes kernel memory, but Oren and Yarom speculate that there may be ways their browser fingerprinting method could be adapted to compromise computing secrets like encryption keys or vulnerable installed software.
We project that about 60% of the searches for individuals of European-descent will result in a third cousin or closer match, which can allow their identification using demographic identifiers. We demonstrate that the technique can also identify research participants of a public sequencing project.
Based on those insights, the researchers used a common machine learning technique, called a generative adversarial network, to artificially create new fingerprints that matched as many partial fingerprints as possible.
