Maxthon Web Browser Sends Sensitive Data To China (securityweek.com) 119

Posted by msmash from the security-woes dept.
Reader wiredmikey writes: Security experts have discovered that the Maxthon web browser collects sensitive information and sends it to a server in China. Researchers warn that the harvested data could be highly valuable for malicious actors. Researchers at Fidelis Cybersecurity and Poland-based Exatel recently found that Maxthon regularly sends a file named ueipdata.zip to a server in Beijing, China, via HTTP. Further analysis (PDF) revealed that ueipdata.zip contains an encrypted file named dat.txt. This file stores information on the operating system, CPU, ad blocker status, homepage URL, websites visited by the user (including online searches), and installed applications and their version number. Interestingly, In 2013, after the NSA surveillance scandal broke, the company boasted about its focus on privacy and security, and the use of strong encryption.

    Security researchers discovered that a Chinese developed web browser you've probably never heard of that claims to have great security actually sends all kinds of personal information about your PC and web searches to a site in Beijing. Also, other Chinese developed web browsers that claim to have great security may do similar things.

      Contrary to what most people think, government in China is far from being a large, single-minded entity. It's more like the EU; lots of small factions and local fiefdoms.

      In the vast majority of cases, industrial or internet "spies" work for private concerns. Of course there's a blurry line because the government has their fingers in everyone's pie in China, either directly or via state employees who leverage their access to public resources to build their own small empire. But it's rarely a simple Big Brother thing.

      Maxthon has been around for over a decade and got the best browser awards or best product of x year a couple of times. If you haven't heard of it you haven't been paying attention(aka the sites you read were pushing their own shit), and you were likely on the firefox bandwagon when it was getting all that attention.

    • I used to use this way back before I switched to FireFox (and before Chrome was even released). Back then, it was one of the best IE wrappers to give you tabs and other functionality that more modern (at the time) browsers were adopting. I ditched it after I switched to FireFox (and, later, Chrome). I didn't even realize they were still around since IE itself now has tabs.

      And you would be right. Because 'citizens in general' are not the ones who end up with your data. This stuff does not go to an IoT toaster in someone's house. The data is collected, stored, and then sold by Maxthon to whom knows who. And you're right, it is not neighbourhood folks/citizens.

    Firefox and Chromium* have a lot of forks, but I would advise against using them. Mozilla and Google have world-class security experts working for them, and when you use generic Firefox/Chrome, you get their security updates the moment they're released out, not when your fork-team's got around to setting them out.

    Suppose you want to use Chromium as a base but are concerned about your privacy with respect to Google, so you don't want to use Chrome. That's perfectly understandable, but using Opera or Vivaldi or Maxthon instead is insanity, since they're all black boxes and you're not really sure what they're doing with your data (case in point, TFA). There's a 100% FLOSS fork of Chromium in the works called Iridium but I cannot recommend it yet because I don't know enough about the competency of their team, but it's definitely worth looking into. Until then, just use vanilla Chromium and rig your own auto-update system [woolyss.com].

    As for Firefox, there's a great extension called Privacy Settings that can optimize all your config flags for privacy (i.e. turn off telemetry, network prefetch, etc.) in just one click. I would recommend however that you keep dom.storage.enabled on, since a lot of websites are unusable without it. Also be wary that security.ssl.require_safe_negotiation needs to be toggled if you need to connect to an insecure website, such as the USPS's.

    *For those unaware: Chromium is the base of Chrome. The only difference between them is that Chrome is shipped with an auto-updater and plugins for Flash and Widevine.

        Why didn't you also mention Microsoft here? *innocent blink*.

        Several reasons.

        1. Firefox and Chrome(ium) are cross-platform. IE/Edge and Safari are not.
        2. Microsoft might have a competent security team (wouldn't bet my life on it though), but their company policy inhibits their browsers from being secure. For instance, it is well known that they share vulnerabilities with certain three-letter agencies before pushing the patches downstream.
        3. Given the Windows 10 debacle, anyone who leaves auto-updates on for any Microsoft OS is either uninformed or a fool.
        4. Even on Windows, there is no particular reason to use IE/Edge instead of Firefox/Chrome(ium). Microsoft's browsers are slower and have less and worse extensions.
        5. Firefox and Chromium are FLOSS, which means (a) you can audit the code yourself for any backdoors/spyware and then compile it yourself, and (b) Mozilla and Google would have to be exceptionally daft to attempt to hide any backdoors/spyware. IE/Edge are proprietary and closed-source, which means they're just as much black boxes as are Maxthon and Opera.

    • I enable every kind of telemetry, crash report on Firefox since they politely ask me to opt in and they are pretty clear about what they do with the data.

      Chrome, p0Edge and Opera (after becoming Chrome)? Never.

  • Big deal, Chrome probably does the same thing, only with the endpoint being at a server Google owns.

    And Win 10 with Edge? If you think that thing doesn't ship data by the borkload back to the lads at Redmond, then you're very, very naive. They even tell you it's shipping data back, except it's the browser AND the OS. I doubt you could so much as move the mouse without Microsoft knowing it.
