chrome extension | Breaking Cybersecurity News | The Hacker News

Google has announced plans to add a new feature in the upcoming version of its Chrome web browser to proactively alert users when an extension they have installed has been removed from the Chrome Web Store. The feature, set for release alongside Chrome 117, allows users to be notified when an add-on has been unpublished by a developer, taken down for violating Chrome Web Store policy, or marked as malware. The tech giant said it intends to highlight such extensions under a "Safety check" category in the "Privacy and security" section of the browser settings page. "When a user clicks 'Review,' they will be taken to their extensions and given the choice to either remove the extension or hide the warning if they wish to keep the extension installed," Oliver Dunk, a developer relations engineer for Chrome extensions,  said . "As in previous versions of Chrome, extensions marked as malware are automatically disabled." The development co

Cybersecurity researchers have discovered a new version of malware called  Rilide  that targets Chromium-based web browsers to steal sensitive data and steal cryptocurrency. "It exhibits a higher level of sophistication through modular design, code obfuscation, adoption to the  Chrome Extension Manifest V3 , and additional features such as the ability to exfiltrate stolen data to a Telegram channel or interval-based screenshot captures," Trustwave security researcher Pawel Knapczyk  said  in a report shared with The Hacker News. Rilide was  first documented  by the cybersecurity company in April 2023, uncovering two different attack chains that made use of Ekipa RAT and Aurora Stealer to deploy rogue browser extensions capable of data and crypto theft. It's sold on dark web forums by an actor named "friezer" for $5,000. The malware is equipped with a wide range of features that allow it to disable other browser add-ons, harvest browsing history and cookies,

The need for vCISO services is growing. SMBs and SMEs are dealing with more third-party risks, tightening regulatory demands and stringent cyber insurance requirements than ever before. However, they often lack the resources and expertise to hire an in-house security executive team. By outsourcing security and compliance leadership to a vCISO, these organizations can more easily obtain cybersecurity expertise specialized for their industry and strengthen their cybersecurity posture. MSPs and MSSPs looking to meet this growing vCISO demand are often faced with the same challenge. The demand for cybersecurity talent far exceeds the supply. This has led to a competitive market where the costs of hiring and retaining skilled professionals can be prohibitive for MSSPs/MSPs as well. The need to maintain expertise of both security and compliance further exacerbates this challenge. Cynomi, the first AI-driven vCISO platform , can help. Cynomi enables you - MSPs, MSSPs and consulting firms

A fake ChatGPT-branded Chrome browser extension has been found to come with capabilities to hijack Facebook accounts and create rogue admin accounts, highlighting one of the different methods cyber criminals are using to distribute malware. "By hijacking high-profile Facebook business accounts, the threat actor creates an elite army of Facebook bots and a malicious paid media apparatus," Guardio Labs researcher Nati Tal  said  in a technical report. "This allows it to push Facebook paid ads at the expense of its victims in a self-propagating worm-like manner." The "Quick access to Chat GPT" extension, which is said to have attracted 2,000 installations per day since March 3, 2023, has since been pulled by Google from the Chrome Web Store as of March 9, 2023. The browser add-on is promoted through Facebook-sponsored posts, and while it offers the ability to connect to the ChatGPT service, it's also engineered to surreptitiously harvest cookies and

A malicious extension for Chromium-based web browsers has been observed to be distributed via a long-standing Windows information stealer called ViperSoftX . Czech-based cybersecurity company dubbed the rogue browser add-on VenomSoftX owing to its standalone features that enable it to access website visits, steal credentials and clipboard data, and even swap cryptocurrency addresses via an adversary-in-the-middle (AiTM) attack. ViperSoftX, which first  came to light  in February 2020, was characterized by  Fortinet  as a JavaScript-based remote access trojan and cryptocurrency stealer. The malware's use of a browser extension to advance its information-gathering goals was documented by Sophos threat analyst  Colin Cowie  earlier this year. "This multi-stage stealer exhibits interesting hiding capabilities, concealed as small PowerShell scripts on a single line in the middle of otherwise innocent-looking large log files, among others," Avast researcher Jan Rubín  said

Five imposter extensions for the Google Chrome web browser masquerading as Netflix viewers and others have been found to track users' browsing activity and profit off retail affiliate programs. "The extensions offer various functions such as enabling users to watch Netflix shows together, website coupons, and taking screenshots of a website," McAfee researchers Oliver Devane and Vallabh Chole  said . "The latter borrows several phrases from another popular extension called GoFullPage." The browser add-ons in question – available via the Chrome Web Store and downloaded 1.4 million times – are as follows - Netflix Party (mmnbenehknklpbendgmgngeaignppnbe) - 800,000 downloads Netflix Party (flijfnhifgdcbhglkneplegafminjnhn) - 300,000 downloads Full Page Screenshot Capture – Screenshotting (pojgkmkfincpdkdgjepkmdekcahmckjp) - 200,000 downloads AutoBuy Flash Sales (gbnahglfafmhaehbdmjedfhdmimjcbed) - 20,000 downloads The extensions are designed to load a pi

More than 1.31 million users attempted to install malicious or unwanted web browser extensions at least once, new findings from cybersecurity firm Kaspersky show. "From January 2020 to June 2022, more than 4.3 million unique users were attacked by adware hiding in browser extensions, which is approximately 70% of all users affected by malicious and unwanted add-ons," the company  said . As many as 1,311,557 users fall under this category in the first half of 2022, per Kaspersky's telemetry data. In comparison, the number of such users peaked in 2020 at 3,660,236, followed by 1,823,263 unique users in 2021. The most prevalent threat is a family of adware called WebSearch, which masquerade as PDF viewers and other utilities, and comes with capabilities to collect and analyze search queries and redirect users to affiliate links. WebSearch is also notable for modifying the browser's start page, which contains a search engine and a number of links to third-party sour

A threat actor operating with interests aligned with North Korea has been deploying a malicious extension on Chromium-based web browsers that's capable of stealing email content from Gmail and AOL. Cybersecurity firm Volexity attributed the malware to an activity cluster it calls  SharpTongue , which is said to share overlaps with an  adversarial collective  publicly referred to under the name  Kimsuky . SharpTongue has a history of singling out individuals working for organizations in the U.S., Europe, and South Korea who "work on topics involving North Korea, nuclear issues, weapons systems, and other matters of strategic interest to North Korea," researchers Paul Rascagneres and Thomas Lancaster  said . Kimsuky 's use of rogue extensions in attacks is not new. In 2018, the actor was seen utilizing a Chrome plugin as part of a campaign called  Stolen Pencil  to infect victims and steal browser cookies and passwords. But the latest espionage effort is different

A malicious browser extension with 350 variants is masquerading as a Google Translate add-on as part of an adware campaign targeting Russian users of Google Chrome, Opera, and Mozilla Firefox browsers. Mobile security firm Zimperium dubbed the malware family  ABCsoup , stating the "extensions are installed onto a victim's machine via a Windows-based executable, bypassing most endpoint security solutions, along with the security controls found in the official extension stores." The rogue browser add-ons come with the same extension ID as that of Google Translate — " aapbdbdomjkkjkaonfhkkikfgjllcleb " — in an attempt to trick users into believing that they have installed a legitimate extension. The extensions are not available on the official browser web stores themselves. Rather they are delivered through different Windows executables that install the add-on on the victim's web browser. In the event the targeted user already has the Google Translate ext

Meta Platforms' WhatsApp and Cloudflare have banded together for a new initiative called Code Verify to validate the authenticity of the messaging service's web app on desktop computers. Available in the form of a Chrome and Edge  browser extension , the  open-source add-on  is designed to "automatically verif[y] the authenticity of the WhatsApp Web code being served to your browser," Facebook  said  in a statement. The goal with Code Verify is to confirm the integrity of the web application and ensure that it hasn't been tampered with to inject malicious code. The social media company is also planning to release Firefox and Safari plugins to achieve the same level of security across browsers. The system works with Cloudflare acting as a third-party audit to compare the cryptographic hash of WhatsApp Web's JavaScript code that's shared by Meta with that of a locally computed hash of the code running on the browser client. Code Verify is also meant t

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

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

Google removed 500 malicious Chrome extensions from its Web Store after they found to inject malicious ads and siphon off user browsing data to servers under the control of attackers. These extensions were part of a malvertising and ad-fraud campaign that's been operating at least since January 2019, although evidence points out the possibility that the actor behind the scheme may have been active since 2017. The findings come as part of a joint investigation by security researcher Jamila Kaya and Cisco-owned Duo Security, which unearthed 70 Chrome Extensions with over 1.7 million installations. Upon sharing the discovery privately with Google, the company went on to identify 430 more problematic browser extensions, all of which have since been deactivated. "The prominence of malvertising as an attack vector will continue to rise as long as tracking-based advertising remains ubiquitous, and particularly if users remain underserved by protection mechanisms," sa

If your Firefox or Chrome browser has any of the below-listed four extensions offered by Avast and its subsidiary AVG installed, you should disable or remove them as soon as possible. Avast Online Security AVG Online Security Avast SafePrice AVG SafePrice Why? Because these four widely installed browser extensions have been caught collecting a lot more data on its millions of users than they are intended to, including your detailed browsing history. Most of you might not even remember downloading and installing these extensions on your web browser, and that's likely because when users install Avast or AVG antivirus on their PCs, the software automatically installs their respective add-ons on the users' browsers. Both online security extensions have been designed to warn users when they visit a malicious or phishing website; whereas, SafePrice extensions help online shoppers learn about best offers, price comparisons, travel deals, and discount coupons from variou

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

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

With so many data breaches happening almost every week, it has become difficult for users to know if their credentials are already in possession of hackers or being circulated freely across the Internet. Thankfully, Google has a solution. Today, February 5, on Safer Internet Day, Google launches a new service that has been designed to alert users when they use an exact combination of username and password for any website that has previously been exposed in any third-party data breach. The new service, which has initially been made available as a free Chrome browser extension called Password Checkup , works by automatically comparing the user's entered credential on any site to an encrypted database that contains over 4 billion compromised credentials. If the credentials are found in the list of compromised ones, Password Checkup will prompt users to change their password. Wondering if Google can see your login credentials? No, the company has used a privacy-oriented i

Google has made several new announcements for its Chrome Web Store that aims at making Chrome extensions more secure and transparent to its users. Over a couple of years, we have seen a significant rise in malicious extensions that appear to offer useful functionalities, while running hidden malicious scripts in the background without the user's knowledge. However, the best part is that Google is aware of the issues and has proactively been working to change the way its Chrome web browser handles extensions. Earlier this year, Google banned extensions using cryptocurrency mining scripts and then in June, the company also disabled inline installation of Chrome extensions completely. The company has also been using machine learning technologies to detect and block malicious extensions. To take a step further, Google announced Monday five major changes that give users more control over certain permissions, enforces security measures, as well as makes the ecosystem more t

Warning! If you are using Chrome browser extension from the MEGA file storage service, uninstall it right now. The official Chrome extension for the MEGA.nz cloud storage service had been compromised and replaced with a malicious version that can steal users' credentials for popular websites like Amazon, Microsoft, Github, and Google, as well as private keys for users' cryptocurrency wallets. On 4 September at 14:30 UTC, an unknown attacker managed to hack into MEGA's Google Chrome web store account and upload a malicious version 3.39.4 of an extension to the web store, according to a blog post published by the company. Malicious MEGA Chrome Extension Steals Passwords Upon installation or auto-update, the malicious extension asked for elevated permissions to access personal information, allowing it to steal credentials from sites like Amazon, Github, and Google, along with online wallets such as MyEtherWallet and MyMonero, and Idex.market cryptocurrency trading

Security researchers have been warning of a few newly detected variants of python -based adware that are being distributed in the wild not only to inject ads but also found installing malicious browser extensions and hidden cryptocurrency miner into victims' computers. Dubbed PBot , or PythonBot , the adware was first uncovered more than a year ago, but since then the malware has evolved, as its authors have been trying different money-making schemes to profit themselves, according to researchers at Kaspersky Labs. The previous versions of the PBot malware were designed to perform man-in-the-browser (MITB) attacks to inject unwanted advertising scripts on web pages visited by the victim, but the newer variants have been found installing malicious ad extensions in the web browser. "Developers are constantly releasing new versions of this modification, each of which complicates the script obfuscation," Kaspersky researchers said in their blog post published today.
