Security researchers have discovered a chip flaw that could nullify hacking protections for millions of devices regardless of their operating system or application running on them, and the worse — the flaw can not be entirely fixed with any mere software update. The vulnerability resides in the way the memory management unit (MMU), a component of many CPUs, works and leads to bypass the Address Space Layout Randomization (ASLR) protection. ASLR is a crucial security defense deployed by all modern operating systems from Windows and Linux to macOS, Android, and the BSDs. In general, ASLR is a memory protection mechanism which randomizes the location where programs run in a device's memory. This, in turn, makes it difficult for attackers to execute malicious payloads in specific spots in memory when exploiting buffer overflows or similar bugs. In short, for attackers, it's like an attempt to burglarize a house blindfolded. But now a group of researchers, known as VUSe

Has Yahoo rebuilt your trust again? If yes, then you need to think once again, as the company is warning its users of another hack. Last year, Yahoo admitted two of the largest data breaches on record. One of which that took place in 2013 disclosed personal details associated with more than 1 Billion Yahoo user accounts . Well, it's happened yet again. Yahoo sent out another round of notifications to its users on Wednesday, warning that their accounts may have been compromised as recently as last year after an ongoing investigation turned up evidence that hackers used forged cookies to log accounts without passwords. The company quietly revealed the data breach in security update in December 2016, but the news was largely overlooked, as the statement from Yahoo provided information on a separate data breach that occurred in August 2013 involving more than 1 billion accounts. The warning message sent Wednesday to some Yahoo users read: "Based on the ongoing i

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,

Security researchers have discovered a new Mac malware allegedly developed by APT28 Russian cyber espionage group who is believed to be responsible for 2016 presidential election hacking scandal. A new variant of the X-Agent spyware is now targeting Apple macOS system that has previously been used in cyber attacks against Windows, iOS, Android, and Linux devices. The malware is designed to steal web browser passwords, take screenshots of the display, detect system configurations, execute files and exfiltrate iPhone backups stored on the computer. The X-Agent malware is tied to Russian hacking group known as APT28 — also known as Fancy Bear, Sofacy, Sednit, and Pawn Storm — that has been operating since at least 2007 and is allegedly linked to the Russian government. "Our past analysis of samples known to be linked to APT28 group shows a number of similarities between the Sofacy/APT28/Sednit Xagent component for Windows/Linux and the Mac OS binary that currently forms

You might be aware of websites, banks, retailers, and advertisers tracking your online activities using different Web "fingerprinting" techniques even in incognito/private mode, but now sites can track you anywhere online — even if you switch browsers. A team of researchers has recently developed a cross-browser fingerprinting technique — the first reliable technique to accurately track users across multiple browsers based on information like extensions, plugins, time zone and whether or not an ad blocker is installed. Previous fingerprinting methods usually only work across a single browser, but the new method uses operating system and hardware level features and works across multiple browsers. This new fingerprinting technique ties digital fingerprint left behind by a Firefox browser to the fingerprint from a Chrome browser or Windows Edge running on the same device. This makes the method particularly useful to advertisers, enabling them to continue serving tar

WhatsApp and Facebook have so far the largest end-to-end encrypted video calling network of all, but now another popular end-to-end encrypted messaging app recommended by whistleblower Edward Snowden is ready to give them a really tough competition. The Signal app, which is widely considered the most secure of all other encrypted messaging apps, released video calling feature on Tuesday for both Android and iOS in a new update. Developed by open source software group Open Whisper System, Signal is a free and open source messaging application specially designed for Android and iOS users to make secure and encrypted messages and voice calls. Even the Signal Protocol powers the end-to-end encryption built into WhatsApp, Facebook Messenger, and Google Allo's Incognito mode as well. Signal has already been providing fully end-to-end encrypted chat and voice calling features, but the newly added feature will make it even easier for privacy conscious people to convey their inf
