Chrome Limits Websites' Direct Access to Private Networks for Security Reasons

Chrome Limits Websites' Direct Access to Private Networks for Security Reasons

Jan 17, 2022
Google Chrome has announced plans to prohibit public websites from directly accessing endpoints located within private networks as part of an upcoming major security shakeup to prevent intrusions via the browser. The proposed change is set to be rolled out in two phases consisting of releases Chrome 98 and Chrome 101 scheduled in the coming months via a newly implemented W3C specification called private network access ( PNA ). "Chrome will start sending a  CORS  preflight request ahead of any private network request for a subresource, which asks for explicit permission from the target server," Titouan Rigoudy and Eiji Kitamura  said . "This preflight request will carry a new header, Access-Control-Request-Private-Network: true, and the response to it must carry a corresponding header, Access-Control-Allow-Private-Network: true." What this means is that starting with Chrome version 101, any website accessible via the internet will be made to seek explicit permi

Google to turn on 2-factor authentication by default for 150 million users

Google to turn on 2-factor authentication by default for 150 million users

Oct 06, 2021
Google has announced plans to automatically enroll about 150 million users into its two-factor authentication scheme by the end of the year as part of its ongoing efforts to prevent unauthorized access to accounts and improve security. In addition, the internet giant said it also intends to require 2 million YouTube creators to switch on the setting, which it calls two-step verification (2SV), to protect their channels from potential takeover attacks. "2SV is strongest when it combines both 'something you know' (like a password) and 'something you have' (like your phone or a security key)," Google's AbdelKarim Mardini and Guemmy Kim  said  in a post, adding "having a second form of authentication dramatically decreases an attacker's chance of gaining access to an account." The rollout follows the  company's proposals  to beef up account sign-ins earlier this May, when it said it intends to "automatically enrolling users in 2SV i

Update Your Chrome Browser to Patch 2 New In-the-Wild 0-Day Exploits

Apr 14, 2021
Google on Tuesday released a new version of Chrome web-browsing software for Windows, Mac, and Linux with patches for two newly discovered security vulnerabilities for both of which it says exploits exist in the wild, allowing attackers to engage in active exploitation. One of the two flaws concerns an insufficient validation of untrusted input in its V8 JavaScript rendering engine (CVE-2021-21220), which was demonstrated by Dataflow Security's Bruno Keith and Niklas Baumstark at the  Pwn2Own 2021  hacking contest last week. While Google moved to fix the flaw quickly, security researcher Rajvardhan Agarwal published a  working exploit  over the weekend by reverse-engineering the patch that the Chromium team pushed to the open-source component, a factor that may have played a crucial role in the release. UPDATE:   Agarwal, in an email to The Hacker News, confirmed that there's one more vulnerability affecting Chromium-based browsers that has been patched in the latest vers

New Chrome 0-day Bug Under Active Attacks – Update Your Browser ASAP!

Mar 03, 2021
Exactly a month after  patching  an actively exploited zero-day flaw in Chrome, Google today rolled out fixes for yet another zero-day vulnerability in the world's most popular web browser that it says is being abused in the wild. Chrome 89.0.4389.72, released by the search giant for Windows, Mac, and Linux on Tuesday, comes with a total of 47 security fixes, the most severe of which concerns an "object lifecycle issue in audio." Tracked as CVE-2021-21166, the security flaw is one of the two bugs reported last month by Alison Huffman of Microsoft Browser Vulnerability Research on February 11. A separate object lifecycle flaw, also identified in the audio component, was reported to Google on February 4, the same day the stable version of Chrome 88 became available. With no additional details, it's not immediately clear if the two security shortcomings are related. Google acknowledged that an exploit for the vulnerability exists in the wild but stopped short of s

Google has patched two more zero-day flaws in the Chrome web browser for desktop, making it the fourth and fifth actively exploited vulnerabilities addressed by the search giant in recent weeks. The company released  86.0.4240.198  for Windows, Mac, and Linux, which it said will be rolling out over the coming days/weeks to all users. Tracked as CVE-2020-16013 and CVE-2020-16017, the flaws were discovered and reported to Google by "anonymous" sources, unlike previous cases, which were uncovered by the company's Project Zero elite security team. Google acknowledged that exploits for both the vulnerabilities exist in the wild but stopped short of sharing more specifics to allow a majority of users to install the fixes. According to the release notes, the two flaws are: CVE-2020-16013:  An "inappropriate implementation" of its V8 JavaScript rendering engine was reported on November 9. CVE-2020-16017:  An  use-after-free  memory corruption issue in Chrome

Google has disclosed details of a new zero-day privilege escalation flaw in the Windows operating system that's being actively exploited in the wild. The elevation of privileges (EoP) vulnerability, tracked as  CVE-2020-17087 , concerns a buffer overflow present since at least Windows 7 in the Windows Kernel Cryptography Driver ("cng.sys") that can be exploited for a sandbox escape. "The bug resides in the cng!CfgAdtpFormatPropertyBlock function and is caused by a 16-bit integer truncation issue," Google's Project Zero researchers Mateusz Jurczyk and Sergei Glazunov noted in their technical write-up. The security team made the details public following a seven-day disclosure deadline because of evidence that it's under active exploit. Project Zero has shared a proof-of-concept exploit (PoC) that can be used to corrupt kernel data and crash vulnerable Windows devices even under default system configurations. What's notable is that the exploit ch

Oct 30, 2020
Cybersecurity researchers have disclosed details about a new watering hole attack targeting the Korean diaspora that exploits vulnerabilities in web browsers such as Google Chrome and Internet Explorer to deploy malware for espionage purposes. Dubbed " Operation Earth Kitsune " by Trend Micro, the campaign involves the use of SLUB (for SLack and githUB) malware and two new backdoors —  dneSpy and agfSpy  — to exfiltrate system information and gain additional control of the compromised machine. The attacks were observed during the months of March, May, and September, according to the cybersecurity firm. Watering hole attacks allow a bad actor to compromise a targeted business by compromising a carefully selected website by inserting an exploit with an intention to gain access to the victim's device and infect it with malware. Operation Earth Kitsune is said to have deployed the spyware samples on websites associated with North Korea, although access to these websites

Critical Flaw Reported in Popular Evernote Extension for Chrome Users

Critical Flaw Reported in Popular Evernote Extension for Chrome Users

Jun 13, 2019
Cybersecurity researchers discover a critical flaw in the popular Evernote Chrome extension that could have allowed hackers to hijack your browser and steal sensitive information from any website you accessed. Evernote is a popular service that helps people taking notes and organize their to-do task lists, and over 4,610,000 users have been using its Evernote Web Clipper Extension for Chrome browser. Discovered by Guardio, the vulnerability ( CVE-2019-12592 ) resided in the ways Evernote Web Clipper extension interacts with websites, iframes and inject scripts, eventually breaking the browser's same-origin policy (SOP) and domain-isolation mechanisms. According to researchers, the vulnerability could allow an attacker-controlled website to execute arbitrary code on the browser in the context of other domains on behalf of users, leading to a Universal Cross-site Scripting (UXSS or Universal XSS) issue. "A full exploit that would allow loading a remote hacker contr
Google Will Prompt European Android Users to Select Preferred Default Browser

Google Will Prompt European Android Users to Select Preferred Default Browser

Mar 20, 2019
Google announced some major changes for its Android mobile operating system in October after the European Commission hit the company with a record $5 billion antitrust fine for pre-installing its own apps and services on third-party Android phones. The European Commission accused Google of forcing Android phone manufacturers to "illegally" tie its proprietary apps and services—specifically, Chrome and Google Search as the default browsers—to Android, unfairly blocking competitors from reaching consumers. This rule led Google to change the way it licenses the Google mobile application suite to Android smartphone makers. Now, Google is further making some changes related to browser and search engine choice. In a blog post published Tuesday, Google announced that the company would prompt Android phone owners in Europe (new and existing ones) in the coming months to choose from a variety of web browsers and search engines for their devices as their default apps. &

Chrome Bug Allowed Hackers to Find Out Everything Facebook Knows About You

Aug 16, 2018
With the release of Chrome 68, Google prominently marks all non-HTTPS websites as 'Not Secure' on its browser to make the web a more secure place for Internet users. If you haven't yet, there is another significant reason to immediately switch to the latest version of the Chrome web browser. Ron Masas, a security researcher from Imperva, has discovered a vulnerability in web browsers that could allow attackers to find everything other web platforms, like Facebook and Google, knows about you—and all they need is just trick you into visiting a website. The vulnerability, identified as CVE-2018-6177 , takes advantage of a weakness in audio/video HTML tags and affects all web browsers powered by "Blink Engine," including Google Chrome. To illustrate the attack scenario, the researcher took an example of Facebook, a popular social media platform that collects in-depth profiling information on its users, including their age, gender, where you have been (loca

Google Developer Discovers a Critical Bug in Modern Web Browsers

Jun 20, 2018
Google researcher has discovered a severe vulnerability in modern web browsers that could have allowed websites you visit to steal the sensitive content of your online accounts from other websites that you have logged-in the same browser. Discovered by Jake Archibald, developer advocate for Google Chrome, the vulnerability resides in the way browsers handle cross-origin requests to video and audio files, which if exploited, could allow remote attackers to even read the content of your Gmail or private Facebook messages. For security reasons, modern web browsers don't allow websites to make cross-origin requests to a different domain unless any domain explicitly allows it. That means, if you visit a website on your browser, it can only request data from the same origin the site was loaded from, preventing it from making any unauthorized request on your behalf in an attempt to steal your data from other sites. However, web browsers do not respond in the same way while fetc

Update Google Chrome Immediately to Patch a High Severity Vulnerability

Jun 06, 2018
You must update your Google Chrome now. Security researcher Michał Bentkowski discovered and reported a high severity vulnerability in Google Chrome in late May, affecting the web browsing software for all major operating systems including Windows, Mac, and Linux. Without revealing any technical detail about the vulnerability, the Chrome security team described the issue as incorrect handling of CSP header ( CVE-2018-6148 ) in a blog post published today. "Access to bug details and links may be kept restricted until a majority of users are updated with a fix. We will also retain restrictions if the bug exists in a third party library that other projects similarly depend on, but haven't yet fixed," the Chrome security team notes. Content Security Policy (CSP) header allows website administrators to add an extra layer of security on a given web page by allowing them to control resources the browser is allowed to load. Mishandling of CSP headers by your web brow

7 Chrome Extensions Spreading Through Facebook Caught Stealing Passwords

May 11, 2018
Luring users on social media to visit lookalike version of popular websites that pop-up a legitimate-looking Chrome extension installation window is one of the most common modus operandi of cybercriminals to spread malware. Security researchers are again warning users of a new malware campaign that has been active since at least March this year and has already infected more than 100,000 users worldwide. Dubbed Nigelthorn, the malware is rapidly spreading through socially engineered links on Facebook and infecting victims' systems with malicious browser extensions that steal their social media credentials, install cryptocurrency miners, and engage them in click fraud. The malware was pushed through at least seven different Chrome browser extensions—all were hosted on Google's official Chrome Web Store. These malicious Chrome browser extensions were first discovered by researchers at cybersecurity firm Radware, after a "well-protected network" of one of its custo

Cybercriminals Hijack Router DNS to Distribute Android Banking Trojan

Apr 16, 2018
Security researchers have been warning about an ongoing malware campaign hijacking Internet routers to distribute Android banking malware that steals users' sensitive information, login credentials and the secret code for two-factor authentication. In order to trick victims into installing the Android malware, dubbed Roaming Mantis , hackers have been hijacking DNS settings on vulnerable and poorly secured routers . DNS hijacking attack allows hackers to intercept traffic, inject rogue ads on web-pages and redirect users to phishing pages designed to trick them into sharing their sensitive information like login credentials, bank account details, and more. Hijacking routers' DNS for a malicious purpose is not new. Previously we reported about widespread DNSChanger and Switcher —both the malware worked by changing the DNS settings of the wireless routers to redirect traffic to malicious websites controlled by attackers. Discovered by security researchers at Kaspersk

Hackers Hijacked Chrome Extension for Web Developers With Over 1 Million Users

Aug 03, 2017
From past few years, spammers and cyber criminals were buying web extensions from their developers and then updating them without informing their users to inject bulk advertisements into every website user visits in order to generate large revenue. But now they have shifted their business model—instead of investing, spammers have started a new wave of phishing attacks aimed at hijacking popular browser extensions. Just two days ago, we reported how cyber criminals managed to compromise the Chrome Web Store account of a German developer team and hijacked Copyfish extension , and then modified it with ad-injection capabilities to distribute spam correspondence to users. Now just yesterday, another popular Chrome extension ' Web Developer ' was hijacked by some unknown attackers, who updated the software to directly inject advertisements into the web browser of over its 1 million users.
