Maxthon has many powerful functions, outstanding performance, and values your privacy. Many built-in functions can greatly improve your work efficiency. Quick send can send web addresses and files between devices. Screenshot allows you to easily take snapshots of regions and pages. Maxnote allows you to manage the knowledge base anytime and anywhere. Maxthon does not record and track your personal behavior so that your privacy truly belongs to you. In addition, Maxthon is specially designed for Web3, with a built-in blockchain wallet VBox, which facilitates cryptocurrency payment. Actually, sometimes you need more than two browsers to distinguish between work and life. Why not give Maxthon a try
As we all know, chrome, edge, and other browsers will record all your behavior, and analyze your browse history and search records for personalized recommendations or other scenarios. Although such records are anonymous, they are still an invasion of privacy. Maxthon browser won't do any of that. Your browsing and search records are saved locally and will not be uploaded to the server. However, if you log in to the Maxthon account, we will encrypt and sync your bookmarks, notes, passwords, form-filling information, and settings to the server for your convenience. We will not access or analyze this information, nor provide them to any third-party company.
S3 Browser is a freeware Windows client for Amazon S3 and Amazon CloudFront. Amazon S3 provides a simple web services interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the web. Amazon CloudFront is a content delivery network (CDN). It can be used to deliver your files using a global network of edge locations.
We call this family of browser modifiers Adrozek. If not detected and blocked, Adrozek adds browser extensions, modifies a specific DLL per target browser, and changes browser settings to insert additional, unauthorized ads into web pages, often on top of legitimate ads from search engines. The intended effect is for users, searching for certain keywords, to inadvertently click on these malware-inserted ads, which lead to affiliated pages. The attackers earn through affiliate advertising programs, which pay by amount of traffic referred to sponsored affiliated pages.
The distribution infrastructure is also very dynamic. Some of the domains were up for just one day, while others were active for longer, up to 120 days. Interestingly, we saw some of the domains distributing clean files like Process Explorer, likely an attempt by the attackers to improve the reputation of their domains and URLs, and evade network-based protections.
Attackers use this sprawling infrastructure to distribute hundreds of thousands of unique Adrozek installer samples. Each of these files is heavily obfuscated and uses a unique file name that follows this format: setup__.exe.
When run, the installer drops an .exe file with a random file name in the %temp% folder. This file in drops the main payload in the Program Files folder using a file name that makes it look like a legitimate audio-related software. We have observed the malware use various names like Audiolava.exe, QuickAudio.exe, and converter.exe. The malware is installed like a usual program that can be accessed through Settings>Apps & features, and registered as a service with the same name.
The malware also tampers with certain browser DLLs. For instance, on Microsoft Edge, it modifies MsEdge.dll to turn off security controls that are crucial for detecting any changes in the Secure Preferences file.
This technique impacts not only Microsoft Edge but other Chromium-based browsers. These browsers store user settings and preferences, such as home page and default search engine, in the Preferences file. For each of the four target browsers, it modifies the relevant DLL:
Browsers have security settings that defend against malware tampering. The Preferences file, for example, contains sensitive data and security settings. Chromium-based browsers detects any unauthorized modifications to these settings through signatures and validation on several preferences. These preferences, as well as configuration parameters, are stored in JSON file name Secure Preferences.
In the past, browser modifiers calculated the hashes like browsers do and update the Secure Preferences accordingly. Adrozek goes one step further and patches the function that launches the integrity check. The two-byte patch nullifies the integrity check, which makes the browser potentially more vulnerable to hijacking or tampering.
With the integrity check disabled, Adrozek proceeds to modify security settings. On Google Chrome or Microsoft Edge, the malware modifies the following entries in the Secure Preferences file to add permissions that enable the malicious extensions to have more control over Chrome APIs:
After tampering with multiple browser components and settings, the malware gains the capability to inject ads on search results on affected browsers. The injection of ads is performed by malicious scripts downloaded from remote servers.
Depending on the search keyword, scripts add related ads at the top of legitimate ads and search results. The number of ads inserted and the sites they point to vary. And while we have not seen these ads point to malware-hosting and other malicious sites, the attackers can presumably make that change anytime. The Adrozek attackers, however, operate the way other browser modifiers do, which is to earn through affiliate ad programs, which pay for referral traffic to certain websites.
On Mozilla Firefox, Adrozek takes things further. It makes the most of its foothold by performing credential theft. It downloads an additional randomly named .exe file, which collects device information and the currently active username. It sends this information to the attacker.
It then starts locating specific files, including login.json. On Mozilla Firefox, the said file, which is located at %appdata%\Roaming\Mozilla\Firefox \Profiles\\logins.json, stores user credentials in encrypted form and the browsing history.
End users who find this threat on their devices are advised to re-install their browsers. Considering the massive infrastructure that was used to distribute this threat on the web, users should also educate themselves about preventing malware infections and the risks of downloading and installing software from untrusted sources and clicking ads or links on suspicious websites. Users should also take advantage of URL filtering solutions, such as Microsoft Defender SmartScreen on Microsoft Edge. Configuring security software to automatically download and install updates, as well as running the latest versions of the operating system and applications and deploying the latest security updates help harden endpoints from threats.
For enterprises, defenders should look to reduce the attack surface for these types of threats. Application control allows organizations to enforce the use of only authorized apps and services. Enterprise-grade browsers like Microsoft Edge provide additional security features like conditional access and Application Guard that defend against threats on the browser.
If the extension was installed on individual computers, then users can configure the extension in their browser settings. If administrators installed the extensions remotely, then administrators configure the extensions but can allow users to configure the extension in their browser settings. These browser settings override the administrator settings. For more information, see Install the Genesys Cloud browser extensions.
The following list describes the settings available to configure the extensions. The names in the list match the names that appear in the browser settings. For more information, see Individual configuration. The names that administrators use to configure the settings programmatically differ slightly. For more information, see Administrator configuration.
By default, logs appear in your browser console that you can use to troubleshoot issues. With this setting, you can configure the browser extension to save logs server side. Customer Care can then access these logs directly. For more information, see Enable server-side logging.
If the extensions were installed manually on individual computers or administrators allow individuals to override the administrator configuration, then individual users can configure the extensions in their browser settings.
Administrators configure the settings during or after installation. (For more information, see Install the Genesys Cloud browser extension.) These settings include one that allows individuals to override any configurations that administrators set. By default, this setting (enableAgentConfiguration) is set to false.
Configure the settings through the MCX (Managed Clients for Mac OS X) preferences for the com.google.Chrome.extensions.onbcflemjnkemjpjcpkkpcnephnpjkcb bundle. To do so, add the following example to a plist file and modify the values. Then import the file using the command-line utility dscl.
Create a manifest (JSON) file with the following content and modify the values. For Windows, you can name the file anything. For Mac OS and Linux, name the file purecloudForFirefox@mypurecloud.com.json.
For global visibility, add the manifest file to /Library/Application Support/Mozilla/ManagedStorage/purecloudForFirefox@mypurecloud.com.json. For per-user visibility, add the manifest file to /Library/Application Support/Mozilla/ManagedStorage/purecloudForFirefox@mypurecloud.com.json. 2ff7e9595c
