Unlock Screen Lock | Breaking Cybersecurity News | The Hacker News

Researchers have discovered an inexpensive attack technique that could be leveraged to brute-force fingerprints on smartphones to bypass user authentication and seize control of the devices. The approach, dubbed  BrutePrint , bypasses limits put in place to counter failed biometric authentication attempts by weaponizing two zero-day vulnerabilities in the smartphone fingerprint authentication (SFA) framework. The flaws, Cancel-After-Match-Fail (CAMF) and Match-After-Lock (MAL), leverage logical defects in the authentication framework, which arises due to insufficient protection of fingerprint data on the Serial Peripheral Interface (SPI) of fingerprint sensors. The result is a "hardware approach to do man-in-the-middle (MitM) attacks for fingerprint image hijacking," researchers Yu Chen and Yiling He  said  in a research paper. "BrutePrint acts as a middleman between fingerprint sensor and  TEE  [Trusted Execution Environment]." The goal, at its core, is to be

Google has resolved a high-severity security issue affecting all Pixel smartphones that could be trivially exploited to unlock the devices. The vulnerability, tracked as  CVE-2022-20465  and reported by security researcher David Schütz in June 2022, was remediated as part of the search giant's  monthly Android update  for November 2022. "The issue allowed an attacker with physical access to bypass the lock screen protections (fingerprint, PIN, etc.) and gain complete access to the user's device," Schütz, who was awarded $70,000 for the lock screen bypass,  said  in a write-up of the flaw. The problem, per the researcher, is rooted in the fact that lock screen protections are completely defeated when following a specific sequence of steps - Supply incorrect fingerprint three times to disable biometric authentication on the locked device Hot swap  the SIM card in the device with an attacker-controlled SIM that has a PIN code set up Enter incorrect SIM pin thric

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

A security enthusiast who discovered a passcode bypass vulnerability in Apple's iOS 12 late last month has now dropped another passcode bypass bug that works on the latest iOS 12.0.1 that was released last week. Jose Rodriguez, a Spanish amateur security researcher, discovered a bug in iOS 12 in late September that allows attackers with physical access to your iPhone to access your contacts and photos. The bug was patched in iOS 12.0.1, but he now discovered a similar iPhone passcode bypass hack that works in 12.0.1 and is easier to execute than the bug Rodriguez discovered and reported two weeks ago. The new hack allows anyone with physical access to your locked iPhone to access your photo album, select photos and send them to anyone using Apple Messages. Since the new hack requires much less effort than the previous one, it leaves any iPhone user vulnerable to a skeptic or distrustful partner, curious college, friend or roommate who could access your iPhone's photo

A Security researcher and hacker, named John Gordon , has found an easy way to bypass the security of locked smartphones running Android 5.0 and 5.1 (Build LMY48M). Many of us use various security locks on our devices like Pattern lock, PIN lock and Password lock in order to protect the privacy of our devices. However, a vulnerability could now allow anyone to take your Android smartphone ( 5.0 build LMY48I ) with locked screen, perform a " MAGIC TRICK " and as a result crash the user interface (UI) for the password screen and gain access to your device. The vulnerability, assigned CVE-2015-3860 , has been dubbed as " Elevation of Privilege Vulnerability in Lockscreen ". How the Attack Works? The secret behind the researcher's "MAGIC TRICK" is as follows: Get the device and open the Emergency dialer screen. Type a long string of numbers or special characters in the input field and copy-n-paste a long string continuously til
