Masslogger Trojan Upgraded to Steal All Your Outlook, Chrome Credentials

Masslogger Trojan Upgraded to Steal All Your Outlook, Chrome Credentials
February 19, 2021Ravie Lakshmanan
A credential stealer infamous for targeting Windows systems has resurfaced in a new phishing campaign that aims to steal credentials from Microsoft Outlook, Google Chrome, and instant messenger apps. Primarily directed against users in Turkey, Latvia, and Italy starting mid-January, the attacks involve the use of  MassLogger  — a .NET-based malware with capabilities to hinder static analysis — building on similar campaigns undertaken by the same actor against users in Bulgaria, Lithuania, Hungary, Estonia, Romania, and Spain in September, October, and November 2020. MassLogger was first spotted in the wild last April, but the presence of a new variant implies malware authors are constantly retooling their arsenal to evade detection and monetize them. "Although operations of the Masslogger trojan have been previously documented, we found the new campaign notable for using the compiled HTML file format to start the infection chain," researchers with Cisco Talos  said  on W

WARNING — Hugely Popular 'The Great Suspender' Chrome Extension Contains Malware

WARNING — Hugely Popular 'The Great Suspender' Chrome Extension Contains Malware
February 06, 2021Ravie Lakshmanan
Google on Thursday removed The Great Suspender , a popular Chrome extension used by millions of users, from its Chrome Web Store for containing malware. It also took the unusual step of deactivating it from users' computers. "This extension contains malware,"  read  a terse notification from Google, but it has since emerged that the add-on stealthily added features that could be exploited to execute arbitrary code from a remote server, including tracking users online and committing advertising fraud. "The old maintainer appears to have sold the extension to parties unknown, who have malicious intent to exploit the users of this extension in advertising fraud, tracking, and more," Calum McConnell  said  in a GitHub post. The extension, which had more than two million installs before it was disabled, would suspend tabs that aren't in use, replacing them with a blank gray screen until they were reloaded upon returning to the tabs in question. Signs of the

New Chrome Browser 0-day Under Active Attack—Update Immediately!
February 04, 2021Ravie Lakshmanan
Google has patched a zero-day vulnerability in Chrome web browser for desktop that it says is being actively exploited in the wild. The company released  88.0.4324.150  for Windows, Mac, and Linux, with a fix for a heap buffer overflow flaw (CVE-2021-21148) in its V8 JavaScript rendering engine. "Google is aware of reports that an exploit for CVE-2021-21148 exists in the wild," the company said in a statement. The security flaw was reported to Google by Mattias Buelens on January 24. Previously on February 2, Google  addressed six issues in Chrome , including one critical use after free vulnerability in Payments (CVE-2021-21142) and four high severity flaws in Extensions, Tab Groups, Fonts, and Navigation features. While it's typical of Google to limit details of the vulnerability until a majority of users are updated with the fix, the development comes weeks after Google and Microsoft  disclosed  attacks carried out by North Korean hackers against security researc

Over a Dozen Chrome Extensions Caught Hijacking Google Search Results for Millions

Over a Dozen Chrome Extensions Caught Hijacking Google Search Results for Millions
February 03, 2021Ravie Lakshmanan
New details have emerged about a vast network of rogue extensions for Chrome and Edge browsers that were found to hijack clicks to links in search results pages to arbitrary URLs, including phishing sites and ads. Collectively called " CacheFlow " by Avast, the 28 extensions in question — including Video Downloader for Facebook, Vimeo Video Downloader, Instagram Story Downloader, VK Unblock — made use of a sneaky trick to mask its true purpose: Leverage  Cache-Control  HTTP header as a covert channel to retrieve commands from an attacker-controlled server. All the  backdoored browser add-ons  have been taken down by Google and Microsoft as of December 18, 2020, to prevent more users from downloading them from the official stores. According to telemetry data gathered by the firm, the top three infected countries were Brazil, Ukraine, and France, followed by Argentina, Spain, Russia, and the U.S. The CacheFlow sequence began when unsuspecting users downloaded one of the

Watch Out! Adrozek Malware Hijacking Chrome, Firefox, Edge, Yandex Browsers

Watch Out! Adrozek Malware Hijacking Chrome, Firefox, Edge, Yandex Browsers
December 11, 2020Ravie Lakshmanan
Microsoft on Thursday took the wraps off an ongoing campaign impacting popular web browsers that stealthily injects malware-infested ads into search results to earn money via affiliate advertising. "Adrozek," as it's called by the Microsoft 365 Defender Research Team, employs an "expansive, dynamic attacker infrastructure" consisting of 159 unique domains, each of which hosts an average of 17,300 unique URLs, which in turn host more than 15,300 unique malware samples. The campaign — which impacts Microsoft Edge, Google Chrome, Yandex Browser, and Mozilla Firefox browsers on Windows — aims to insert additional, unauthorized ads on top of legitimate ads displayed on search engine results pages, leading users to click on these ads inadvertently. Microsoft said the persistent browser modifier malware has been observed since May this year, with over 30,000 devices affected every day at its peak in August. "Cybercriminals abusing affiliate programs is not

New Chrome Zero-Day Under Active Attacks – Update Your Browser
November 03, 2020Ravie Lakshmanan
Google has patched a second actively exploited zero-day flaw in the Chrome browser in two weeks, along with addressing nine other security vulnerabilities in its latest update. The company  released  86.0.4240.183 for Windows, Mac, and Linux, which it said will be rolling out over the coming days/weeks to all users. The zero-day flaw, tracked as  CVE-2020-16009 , was reported by Clement Lecigne of Google's Threat Analysis Group (TAG) and Samuel Groß of Google Project Zero on October 29. The company also warned that it "is aware of reports that an exploit for CVE-2020-16009 exists in the wild." Google hasn't made any details about the bug or the exploit used by threat actors public so as to allow a majority of users to install the updates and prevent other adversaries from developing their own exploits leveraging the flaw. But Ben Hawkes, Google Project Zero's technical lead,  said  CVE-2020-16009 concerned an "inappropriate implementation" of its

Over 100 New Chrome Browser Extensions Caught Spying On Users

Over 100 New Chrome Browser Extensions Caught Spying On Users
June 22, 2020Ravie Lakshmanan
Google recently removed 106 more extensions from its Chrome Web Store after they were found illegally collecting sensitive user data as part of a "massive global surveillance campaign" targeting oil and gas, finance, and healthcare sectors. Awake Security, which disclosed the findings late last week, said the malicious browser add-ons were tied back to a single internet domain registrar, GalComm. However, it's not immediately clear who is behind the spyware effort. "This campaign and the Chrome extensions involved performed operations such as taking screenshots of the victim device, loading malware, reading the clipboard, and actively harvesting tokens and user input," Awake Security said. The extensions in question posed as utilities offering capabilities to convert files from one format to the other, among other tools for secure browsing, while relying on thousands of fake reviews to trick unsuspecting users into installing them. Furthermore, the

49 New Google Chrome Extensions Caught Hijacking Cryptocurrency Wallets

49 New Google Chrome Extensions Caught Hijacking Cryptocurrency Wallets
April 15, 2020Ravie Lakshmanan
Google has ousted 49 Chrome browser extensions from its Web Store that masqueraded as cryptocurrency wallets but contained malicious code to siphon off sensitive information and empty the digital currencies. The 49 browser add-ons, potentially the work of Russian threat actors, were identified  (find the list here) by researchers from MyCrypto and PhishFort. "Essentially, the extensions are phishing for secrets — mnemonic phrases , private keys, and keystore files," explained Harry Denley, director of security at MyCrypto. "Once the user has entered them, the extension sends an HTTP POST request to its backend, where the bad actors receive the secrets and empty the accounts." Although the offending extensions were removed within 24 hours after they were reported to Google, MyCrypto's analysis showed that they began to appear on the Web Store as early as February 2020, before ramping up in subsequent months. In addition, all the extensions functioned a

New Chrome 0-day Bug Under Active Attacks – Update Your Browser Now!
November 01, 2019Swati Khandelwal
Attention readers, if you are using Chrome on your Windows, Mac, and Linux computers, you need to update your web browsing software immediately to the latest version Google released earlier today. With the release of Chrome 78.0.3904.87, Google is warning billions of users to install an urgent software update immediately to patch two high severity vulnerabilities, one of which attackers are actively exploiting in the wild to hijack computers. Without revealing technical details of the vulnerability, the Chrome security team only says that both issues are use-after-free vulnerabilities, one affecting Chrome's audio component ( CVE-2019-13720 ) while the other resides in the PDFium ( CVE-2019-13721 ) library. The use-after-free vulnerability is a class of memory corruption issues that allows corruption or modification of data in the memory, enabling an unprivileged user to escalate privileges on an affected system or software. Thus, both flaws could enable remote attackers

Chrome for Android Enables Site Isolation Security Feature for All Sites with Login

Chrome for Android Enables Site Isolation Security Feature for All Sites with Login
October 17, 2019Swati Khandelwal
After enabling ' Site Isolation ' security feature in Chrome for desktops last year, Google has now finally introduced 'the extra line of defence' for Android smartphone users surfing the Internet over the Chrome web browser. In brief, Site Isolation is a security feature that adds an additional boundary between websites by ensuring that pages from different sites end up in different sandboxed processes in the browser. Since each site in the browser gets its own isolated process, in case of a browser flaw or Spectre like side-channel vulnerability, the feature makes it harder for attackers or malicious websites to access or steal cross-site data of your accounts on other websites. Site Isolation helps protect many types of sensitive data, including authentication cookies, stored passwords, network data, stored permissions, as well as cross-origin messaging that help sites securely pass messages across domains. The feature gained attention in January 2018,

Two Widely Used Ad Blocker Extensions for Chrome Caught in Ad Fraud Scheme

Two Widely Used Ad Blocker Extensions for Chrome Caught in Ad Fraud Scheme
September 20, 2019Swati Khandelwal
Two widely used Adblocker Google Chrome extensions , posing as the original — AdBlock and uBlock Origin — extensions on Chrome Web Store, have been caught stuffing cookies in the web browser of millions of users to generate affiliate income from referral schemes fraudulently. There's no doubt web extensions add a lot of useful features to web browsers, making your online experience great and aiding productivity, but at the same time, they also pose huge threats to both your privacy and security. Being the most over-sighted weakest link in the browser security model, extensions sit between the browser application and the Internet — from where they look for the websites you visit and subsequently can intercept, modify, and block any requests, based on the functionalities they have been designed for. Apart from the extensions which are purposely created with malicious intent , in recent years we have also seen some of the most popular legitimate Chrome and Firefox extensions g

For now, Chrome security team has only revealed that all four vulnerabilities are use-after-free issues in different components of the web browser, as mentioned below, the critical of which could lead to remote code execution attacks. The use-after-free vulnerability is a class of memory corruption issue that allows corruption or modificat

Google Chrome to Introduce Improved Cookie Controls Against Online Tracking

Google Chrome to Introduce Improved Cookie Controls Against Online Tracking
May 08, 2019Mohit Kumar
At the company's I/O 2019 developer conference, Google has announced its plan to introduce two new privacy and security-oriented features in the upcoming versions of its Chrome web browser. In an attempt to allow users to block online tracking, Google has announced two new features—Improved SameSite Cookies and Fingerprinting Protection—that will be previewed by Google in the Chrome web browser later this year. Cookies, also referred to as HTTP cookies or browser cookies, are the small pieces of information that websites store on your computer, which play an important role in improving your online experience. Cookies are created by a web browser when a user loads a particular website, which helps the website to remember information about your visit, like your login information, preferred language, items in the shopping cart and other settings. However, cookies are also being widely used to identify users and track their activities not only on the site that issued a cooki

Microsoft Releases First Preview Builds of Chromium-based Edge Browser

Microsoft Releases First Preview Builds of Chromium-based Edge Browser
April 08, 2019Mohit Kumar
Microsoft today finally released the first new reborn version of its Edge browser that the company rebuilds from scratch using Chromium engine, the same open-source web rendering engine that powers Google's Chrome browser. However, the Chromium-based Edge browser builds haven't yet entered the stable or even the beta release; instead, Microsoft has released two testing-purpose preview builds for developers. Both previews build— "Canary"  that will be updated daily, and "Developer"  that will be updated every week—are now available for download from the Microsoft's new Edge insider website . Here's how Microsoft differentiates Canary and Developer builds: "Every night, we produce a build of Microsoft Edge — if it passes automated testing, we'll release it to the Canary channel. We use this same channel internally to validate bug fixes and test brand new features. The Canary channel is truly the bleeding edge, so you may discover bugs

Google Will Prompt European Android Users to Select Preferred Default Browser

Google Will Prompt European Android Users to Select Preferred Default Browser
March 20, 2019Swati Khandelwal
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. &

You must update your Google Chrome immediately to the latest version of the web browsing application. Security researcher Clement Lecigne of Google's Threat Analysis Group discovered and reported a high severity vulnerability in Chrome late last month that could allow remote attackers to execute arbitrary code and take full control of the computers. The vulnerability, assigned as CVE-2019-5786 , affects the web browsing software for all major operating systems including Microsoft Windows, Apple macOS, and Linux. Without revealing technical details of the vulnerability, the Chrome security team only says the issue is a use-after-free vulnerability in the FileReader component of the Chrome browser, which leads to remote code execution attacks. What's more worrisome? Google warned that this zero-day RCE vulnerability is actively being exploited in the wild by attackers to target Chrome users. "Access to bug details and links may be kept restricted until a majo

Thousands of Google Chromecast Devices Hijacked to Promote PewDiePie
January 03, 2019Mohit Kumar
A group of hackers has hijacked tens of thousands of Google's Chromecast streaming dongles, Google Home smart speakers and smart TVs with built-in Chromecast technology in recent weeks by exploiting a bug that's allegedly been ignored by Google for almost five years. The attackers, who go by Twitter handles @HackerGiraffe and @j3ws3r, managed to hijack Chromecasts' feeds and display a pop-up, spreading a security warning as well as controversial YouTube star PewDiePie propaganda. The hackers are the same ones who hijacked more than 50,000 internet-connected printers worldwide late last year by exploiting vulnerable printers to print out flyers asking everyone to subscribe to PewDiePie YouTube channel. This time, the hackers remotely scanned the internet for compatible devices, including Chromecasts, exposed to the internet through poorly configured routers that have Universal Plug and Play [UPnP] enabled by default. The hackers then exploited a design flaw in Chrome

Google Partially Patches Flaw in Chrome for Android 3 Years After Disclosure

Google Partially Patches Flaw in Chrome for Android 3 Years After Disclosure
January 03, 2019Swati Khandelwal
Google has finally patched a privacy vulnerability in its Chrome web browser for Android that exposes users' device model and firmware version, eventually enabling remote attackers to identify unpatched devices and exploit known vulnerabilities. The vulnerability, which has not yet given any CVE number, is an information disclosure bug that resides in the way the Google Chrome for Android generates 'User Agent' string containing the Android version number and build tag information, which includes device name and its firmware build. This information is also sent to applications using WebView and Chrome Tabs APIs, which can be used to track users and fingerprint devices on which they are running. For example: Mozilla/5.0 (Linux; Android 5.1.1; Nexus 6 Build/LYZ28K ) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.34 Mobile Safari/537.36 Yakov Shafranovich, a contributor at Nightwatch Cybersecurity firm, initially reported this issue to Google three years a

Microsoft building Chrome-based browser to replace Edge on Windows 10
December 04, 2018Mohit Kumar
It is no secret how miserably Microsoft's 3-year-old Edge web browser has failed to compete against Google Chrome despite substantial investment and continuous improvements. According to the latest round of tech rumors, Microsoft has given up on Edge and reportedly building a new Chromium -based web browser, dubbed project codename " Anaheim " internally, that will replace Edge on Windows 10 operating system as its new default browser, a journalist at WindowsCentral learned. Though there is no mention of Project Anaheim on the Microsoft website as of now (except Anaheim Convention Center at California), many speculate that the new built-in browser could appear in the 19H1 development cycle of Microsoft's Insider Preview program. According to the report, the new browser will be powered by Blink rendering engine used by Chromium, one that also powers Google's Chrome browser, instead of Microsoft's own EdgeHTML engine. Chromium is an open-source Web b
