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...

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...

After targeting Windows-based computers over the past few years, hackers are now shifting their interest to Macs as well. The emergence of the first macro-based Word document attack against Apple's macOS platform is the latest example to prove this. The concept of Macros dates back to 1990s. You might be familiar with the message that reads: " Warning: This document contains macros. " Macro is a series of commands and actions that help automate some tasks. Microsoft Office programs support Macros written in Visual Basic for Applications (VBA), but they can also be used for malicious activities like installing malware. Until now, hackers were cleverly using this technique to target Windows. However, security researchers have now detected the first in-the-wild instance of hackers are making use of malicious macros in Word documents to install malware on Mac computers and steal your data – an old Windows technique. The hack tricks victims into opening infected W...
