MB BLOCKS OUTGOING CONNTECTION TO WEBSITE "DEREVO.BIT"


Recommended Posts

Hello,

I recently installed Malwarebytes and today I happen to receive the pop up message of a blocking an outgoing connection which is completely similar (if not identical) to the one described in this topic: https://forums.malwarebytes.com/topic/199159-every-minute-mb-blocks-an-outgoing-connection-help-me-remove-it/

Unfortunately I am not so good at technology myself, so I would like to ask for your help not only to remove the annoying problem, but to be guided through the process.

Thank you in advance for your help!

Hi itssimone :)

My name is Aura and I'll be assisting you with your malware issue. Since we'll be working together, you can call me Aura or Yoan, which is my real name, it's up to you! Now that we've broke the ice, I'll just ask you a few things during the time we'll be working together to clean your system and get it back to an operational state.

  • As you'll notice, the logs we are asking for here are quite lenghty, so it's normal for me to not reply exactly after you post them. This is because I need some time to analyse them and then act accordingly. However, I'll always reply within 24 hours, 48 hours at most if something unexpected happens;
  • As long as I'm assisting you on Malwarebytes Forums, in this thread, I'll ask you to not seek assistance anywhere else for any issue related to the system we are working on. If you have an issue, question, etc. about your computer, please ask it in this thread and I'll assist you;
  • The same principle applies to any modifications you make to your system, I would like you to ask me before you do any manipulations that aren't in the instructions I posted. This is to ensure that we are operating in sync and I know exactly what's happening on your system;
  • If you aren't sure about an instruction I'm giving you, ask me about it. This is to ensure that the clean-up process goes without any issue. I'll answer you and even give you more precise instructions/explanations if you need. There's no shame in asking questions here, better be safe than sorry!;
  • If you don't reply to your thread within 3 days, I'll bump this thread to let you know that I'm waiting for you. If you don't reply after 5 days, it'll be closed. If you return after that period, you can send me a PM to get it unlocked and we'll continue where we left off;
  • Since malware can work quickly, we want to get rid of them as fast as we can, before they make unknown changes to the system. This being said, I would appreciate if you could reply to this thread within 24 hours of me posting. This way, we'll have a good clean-up rhythm and the chances of complications will be reduced;
  • I'm against any form of pirated, illegal and counterfeit software and material. So if you have any installed on your system, I'll ask you to uninstall them right now. You don't have to tell me if you indeed had some or not, I'll give you the benefit of the doubt. Plus, this would be against Malwarebytes Forums's rules;
  • In the end, you are the one asking for assistance here. So if you wish to go a different way during the clean-up, like format and reinstall Windows, you are free to do so. I would appreciate you to let me know about it first, and if you need, I can also assist you in the process;
  • I would appreciate if you were to stay with me until the end, which means, until I declare your system clean. Just because your system isn't behaving weirdly anymore, or is running better than before, it doesn't mean that the infection is completely gone;
    This being said, I have a full time job so sometimes it'll take longer for me to reply to you. Don't worry, you'll be my first priority as soon as I get home and have time to look at your thread;


This being said, it's time to clean-up some malware, so let's get started, shall we? :)

Follow the instructions in the thread below and provide me both logs (FRST.txt and Addition.txt).

Hello Yoan.

 

Thank you very much for your reply. Before we start, I may want to explain something that happened to me yesterday, before I got to the point of receving the pop-up message from Malwarebytes saying it's blocking the "derevo.bit" domain. While surfing the net, I eventually got to an undesired pop-up site, who made my Google Chrome search engine change from www.google.com to "navsmart.info", and then into another one who I don't recall the exact name, but I'm sure it ended it in ".ru". I searched how to get rid of it on the internet and I got to malwarebytes.com, where I downloaded the Premium Trial versionand installed the program, launched and apparently got rid of the issue. After that though, the only problem I seem to see is this "derevo.bit" blocking message I get every minute. As you said anyway, I am pretty sure the whole problem is not completely gone. So, once again, I am really grateful for your help. Also, I ask you to be a little bit patient with me, since English is not my mother language and I am not very good with computers and technology myself (not even when it's written in my own language!). Attached to this reply, you can find the screenshot I saved of the message I got, and I noticed, the port and the IP addresses mentioned in the pop-up message always change.

 

I've read and understood all the points you described me, and I'm going to do my best to stick to them correctly. Please inform me if I'll ever be doing something wrong.

I've followed your instructions and I've done what it was suggested on the thread you linked me. Here's what I've done and what you can find attached to this reply of mine

  • I did the Threat Scan with Malwarebytes - the log is the .txt file called "MALWAREBYTES LOG AFTER THREAT SCAN.txt".
  •  I've downloaded the Farbar Recovery Scan Tool and run it. The logs you required, called "FRST.txt" and "Addition.txt", are also attached to this reply.
  • Altogether, you should be able to find 4 files attached to this reply.

I would be glad, if there was a way not to make those three files available to the public. If otherwise this won't be possibile, according to the forum rules, I will accept it and leave them as they are. To state it clearly, I have nothing against you or anyone of the administrators of this forum, to whom instead I am very grateful. I hope you understand.

 

I once again thank you a lot for your help and I wish you a nice day, while waiting for a kind response from you.

Regards

itssimone

No worries, English isn't my native language either, so we're in the same boat :)

Only Trusted Advisors, Experts and Malwarebytes employees have access to these logs. So they aren't "public" per say, is that fine?

Now, we'll run a first fix with FRST. After running the fix (by following the instructions below), a .zip file called "DATE-TIME.zip" should be located on your desktop (the DATE and TIME will be the date and time on which the FRST fix was ran). I would like you to upload that .zip file to the link below.

Follow the instructions below to execute a fix on your system using FRST, and provide the log in your next reply.

  • Download the attached fixlist.txt file, and save it on your Desktop (or wherever your FRST.exe/FRST64.exe executable is located);
  • Right-click on the FRST executable and select Spcusrh.pngRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users);
  • Click on the Fix button;
    NYA5Cbr.png
  • On completion, a message will come up saying that the fix has been completed and it'll open a log in Notepad;
  • Copy and paste its content in your next reply;

Your next reply(ies) should include:

  • Confirmation that you uploaded the DATE-TIME.zip file to the link provided above;
  • Copy/pasted content of FRST's fixlog.txt;

Thank you for your reply! This is just a quick reply to ask one thing. I've been running the Farbar Recovery Scan Tool for over an hour now, right after you replied to my answer. I have gotten both the Fixlog.txt file and the DATE-TIME.zip folder on my desktop although the tool is still running and hasn't 'officially' completed the fixing. Is it normal? Do I just have to wait?

 

Thank you for your patience!

Wile waiting for a reply from you, not knowing what to do, I've let the Farbar Recovery Scan Tool run through the night. It's morning now, and the program is still running as I left him last night. Anyway, attached to this reply, you can find the fixlog.txt file attached.

 

Regarding the files attached to my replies, if they are available to the administrators and experts of the forum only, it's fine for me. I just wouldn't want them to be available to the public, as for instance it seemed to me they were in the thread with the same issue as I have, which is the following one: https://forums.malwarebytes.com/topic/199159-every-minute-mb-blocks-an-outgoing-connection-help-me-remove-it/.

 

Thank you again.

Like I thought, the FRST fix is hanging at the Zip: command, so I'll just remove it. Follow the same instructions as above to run the fix, but use the attached fixlist below instead.

And if you copy/paste the logs here, everyone can see them. But if you attach them (like you've been doing since the start), only Trusted Advisors, Experts and the Malwarebytes Staff can download and read them.

Thank you!

Yesterday, since the Farbar Recovery Scan Tool was stuck for hours, I forcedly closed it. Now I re-followed the process using the new fixlist.txt file. It created a Fixlog.txt file quite quickly, but unfortunately I can't seem to find any zipped folder/file on my desktop, nor anywhere else on my computer. Is it something I did wrong?

Attached to this reply you can find the new Fixlog.txt file. Thank you once again for your patience and help.

This is normal. I removed the command that was supposed to create the .zip file from the fixlist.txt, as it was making FRST hang.

Now, let's do a sweep with JRT and AdwCleaner.

iT103hr.pngJunkware Removal Tool (JRT)

  • Download Junkware Removal Tool (JRT) and move it to your Desktop;
  • Right-click on JRT.exe and select Spcusrh.pngRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users);
  • Press on any key to launch the scan and let it complete;

    Credits : BleepingComputer.com
  • Once the scan is complete, a log will open. Please copy/paste the content of the output log in your next reply;

zcMPezJ.pngAdwCleaner - Fix Mode

  • Download AdwCleaner and move it to your Desktop;
  • Right-click on AdwCleaner.exe and select Spcusrh.pngRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users);
  • Accept the EULA (I accept), let the database update, then click on Scan;
  • Let the scan complete. Once it's done, make sure that every item listed in the different tabs is checked and click on the Cleaning button. This will kill all the active processes;
    MV5ejgW.png
  • Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it;
  • After the restart, a log will open when logging in. Please copy/paste the content of that log in your next reply;

Your next reply(ies) should therefore contain:

  • Copy/pasted JRT log;
  • Copy/pasted AdwCleaner clean log;

Thank you! I followed the instructions you gave me and, if it is fine for you, always according to the previously mentioned privacy kept so when attaching the logs files instead of copying/pasting their content in a reply, I would like to keep doing the same. Therefore, attached to this reply, you can find the JRT.txt and the AdwCleaner[C0].txt logs. I hope it is fine for you.

After I was done with the last procedure, and with sending you the relative logs, I haven't received any block notification from Malwarebytes in the next 20 minutes. As of right now, after I just turned my computer on, I still seem no longer to get any. If the whole issue can be considered as solved, I would thank you very much for your help, your kindness and your patience, whilst hoping I am allowed to reply to this thread once again in case the issue happens again in the near future.

In the opposite case, according to which the procedure is not concluded, I will await for your kind instructions.

Best regards

Hello Yoan.

No, luckily everything seems to work nice and fine and I do no longer get any notifications. Let's hope it will stay this way! If you agree on this, I think you could close this thread. In case in the (hopefully not so near) future I was to get some other similar issues, I will surely get in contact with Malwarebytes forum, opening a new thread. 

I can never thank you enough for your help! :)

Glad to hear that itssimone! And no problem, you're welcome :)

Since there are no signs of infection anymore in your logs, and you just told me that there are no more issues left to address, I guess we're done here. We'll wrap it up by running DelFix to delete the tools and logs that were used in this clean-up.

BWuhenj.pngDelFix
Follow the instructions below to download and execute DelFix.

  • Download DelFix and move the executable to your Desktop;
  • Right-click on DelFix.exe and select Spcusrh.pngRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users);
  • Check the following options :
    • Activate UAC;
    • Remove disinfection tools;
    • Create registry backup;
    • Purge system restore;
    • Reset system settings;
  • Once all the options mentionned above are checked, click on Run;
  • After DelFix is done running, a log will open. Please copy/paste the content of the output log in your next reply;

Qt25440.pngTips, tricks, advice and recommendations

Now it's time to give you some tips, tricks, advice and recommendations on how to protect your system and prevent you from being infected in the future. This is where I'll explain basic security measures that you should take to protect and harden your system, and also make sure it stays as safe and secure as possible against hackers and malware. You are free to ignore the recommendations listed below, although I obviously do not recommend it. If you have any questions about one of the points covered in the speech below, feel free to ask me your questions here directly so I can answer them and guide you.

Windows Updates

Keeping Windows up to date is one of the first steps in having a safe and secure system. The Security Updates that Windows receives are meant to fix exploits and flaws in it that makes it more secure and not exploitable by hackers. In order to do that, you should always install the Security Updates, known as "Important Updates" on your Windows system. These updates are released on the second Tuesday of every month, but some are also released before if they are emergency/critical Security Updates. Let's make sure that you have all your Important Updates and Recommended Updates installed and that your Windows Updates are set to be installed automatically.

Keeping your programs up-to-date

Like keeping Windows updated, keeping your installed programs up-to-date is another important step in having a safe and secure system. Outdated programs can be exploited by hackers and malware to infect a system and take it over. This is especially true today with the rise of Exploit Kits which is one of the biggest attack vectors to distribute malware. Therefore, you should always keep vulnerable programs like Adobe Flash Player, Adobe Shockwave Player, Java, Silverlight, etc. updated to their most recent version (even better, you don't have to install them if you don't use them). Programs like eLDnJfI.pngSecuniaPSI and dqVs5wj.pngHeimdal Free will scan your system for outdated programs, and help you identify them, as well as update them.

Antivirus, Antimalware, Firewall and Anti-Exploit/Ransomware

Having a decent security setup (led by an Antivirus) is the most crucial step to protect a system. These programs are a layer of defence that will prevent a system from being infected, or if it somehow ends up infected, help mitigate the infection and remediate it. Ideally, you should have on your system one Antivirus (never more than one installed at the time), one Antimalware (you can install multiple of these, assuming they do not conflict with each other and the other security programs installed), one Firewall and if you wish, one Anti-Exploit and/or Anti-Ransomware (since Ransomware are currently the most dangerous threat around and it can hit anywhere). Here are a few programs worth checking out if you don't have one yet.

Note: The programs listed below are all free to use or they have some sort of trial. Some of them have a paid version that provides more features, while a lot of other good programs only have a paid version but aren't listed there (such as Kaspersky and ESET Antivirus products).

Antivirus

Antimalware

Firewall
Starting in Windows Vista, the Windows Firewall greatly improved and will satisfy the needs of most users. If you do not have an Internet Suite Antivirus program (which includes a firewall) and you want to use a 3rd party firewall, you can consider the options below.

  • 7p3JzTS.pngGlassWire - Has both a free and paid version (with different packages);
  • MQIMh6k.pngWindows Firewall Control - Gives you more control over your Windows Firewall;
  • 5RXGshU.pngTinyWall - Lightweight firewall implementing the Windows Firewall and giving you more control over it;

Anti-Exploit/Anti-Ransomware

Web Browsers and Web Browsing

Web Browsers could be considered as the closest door between a malware and your system. This is where most malware goes through to infect a system, and therefore it should be the program(s) you want to secure the most. There are two ways of going about it: hardening your web browser via extensions, and having good browsing habits. 

Hardening your web browser means to install extensions that will help it protect itself (and your system on the same occasion) against Exploit Kits, MiTM attacks, etc. but also you at the same time. Here are a few extensions that I recommend you to install.

  • uBlock Origin: Efficient multi-purpose blocker that is lightweight on RAM and CPU usage (Google Chrome and Mozilla Firefox, called uBlock on Opera);
  • HTTPS Everywhere: Extension that converts your HTTP (unencrypted) requests to HTTPS (encrypted) ones (Google Chrome, Mozilla Firefox and Opera);
  • Web of Trust: Website reputation, rating and review extension that will help you quickly identify bad and suspicious sites from good ones (every web browsers);
  • NoScript: NoScript is a script blocker (Java, Flash, JavaScript, etc.) for Mozilla Firefox and Firefox-based browsers (Mozilla Firefox and Firefox-based web browsers);
  • uMatrix: For advanced users, a point and click matrix-like extensions that allow you to control requests done on a webpage (based on source, destination and type) (Google Chrome, Mozilla Firefox and Opera);
  • LastPass: Secure password manager allowing you to create, manage, and use passwords you save in your LastPass account (every web browser);

As for safe browsing habits, you can find tons of guides, tutorials, articles, etc. online that will highlight the basics you need to follow (only visit websites you trust, do not click on ads, do not download files from untrusted sources, use a password manager, always verify the URL of a website and make sure it's correctly typed, etc.), and even what you can do if you want to take it a step further (create a fake email address for spam emails, browse the web in a privacy mode, etc.). Here are a few:


As you can see, there are plenty of resources out there. Simply Googling "good browsing habits" or "safe browsing habits" should allow you to find a lot of them.

Other recommendations

Even if you follow every recommendation that I listed here, in the end, it's also your job to be careful when browsing the web and downloading files if you don't want to get infected. Therefore, if you use your brain (common sense) when browsing the web, downloading programs and files, etc., you have far less chances to get infected by a malware. If for example you're not sure if a website is legitimate or not, or if a file is safe to download and execute, or if a program looks "too good" to be free, I suggest you to avoid going to that website, downloading that file or using that program.

Here are a few guides, tutorials, articles, etc. that you could read in order to learn more about computer protection and security to improve your current computer protection setup but also improve your good web browsing and computer usage practices :


gRvSooB.pngThe End!

And that's it! Now that you know more about how to protect your computer and secure it, you're good to go back to your online activities, but in a safe and secure way! You are also free to stay on the forums and ask for help in different topics if you ever need to. Just make sure that you post your question/issue in the right section to get the best assistance possible. And if you ever get infected again (which I hope you wont!), you can always comeback in this section to get another checkup with one of our trained malware removal member.

Do you have any questions before I close this thread? :)
