Could you please investigate the attached exe file and let us know whether there is something suspicious with it or not.

Staff blender Posted June 21, 2018 Staff ID:1251626 Share Posted June 21, 2018 Do you have a log of this detection? Currently I cannot reproduce it. Link to post Share on other sites More sharing options...
Staff blender Posted June 21, 2018 Staff ID:1251627 Share Posted June 21, 2018 Oops - scratch that. This has been fixed for some time now. Link to post Share on other sites More sharing options...
netrics Posted June 21, 2018 Author ID:1251636 Share Posted June 21, 2018 What do you mean by "some time"? It was recognize malware 3 time on 18th/19th June this week. Link to post Share on other sites More sharing options...
Staff blender Posted June 21, 2018 Staff ID:1251638 Share Posted June 21, 2018 All the exact same file? We whitelisted this exact file the 18th of May. Link to post Share on other sites More sharing options...
netrics Posted June 21, 2018 Author ID:1251642 Share Posted June 21, 2018 yes - this file has been on the system since February this year .... Link to post Share on other sites More sharing options...
Staff blender Posted June 21, 2018 Staff ID:1251644 Share Posted June 21, 2018 I am going to have someone pop in to have a look. I'm sure he will be able to figure out what is happening. He may want other logs but while waiting on him, can you grab a screenshot showing the version information from MBAM? Settings>> about Just a screenshot of the Version Information section should be good for now. What steps would he have to take to reproduce the issue? Actually running the file or is it being detected by a scan or.. ? Thanks! Link to post Share on other sites More sharing options...
netrics Posted June 21, 2018 Author ID:1251645 Share Posted June 21, 2018 you would have to install Oracle Weblogic Software .... beasvc.exe is part of this and is installed as a windows service .... probably not easy to reproduce Oracle WebLogic Server 11g Release 1 (10.3.6.0) Upgrade Oracle WebLogic Server Patch Set Update 10.3.6.0.171017 Java™ SE Development Kit 6, Update 161 (JDK 6u161) Link to post Share on other sites More sharing options...
Staff blender Posted June 21, 2018 Staff ID:1251647 Share Posted June 21, 2018 Thank you. Can download & run the support tool as instructed on this page? Post the resulting zip from your desktop please. Either myself or Bob will have a look once posted. Thanks! Link to post Share on other sites More sharing options...

Staff blender Posted June 21, 2018 Staff ID:1251653 Share Posted June 21, 2018 Hello, It looks like MBAM is having trouble to reach our back-end where it gets the whitelisted info from. Because the support tool was run as a limited user, it couldn't create certain logs. Let's try & get them with this. Please download Farbar Recovery Scan Tool from here http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/ and save it to your desktop. Note: You need to run the version compatible with your system – for you, this would be the 64-bit version. **After you click the Download Now 64-bit, another page will open — DO NOT CLICK ANY ADDITIONAL 'download now' buttons, just wait and look toward the bottom of your browser for the option to Run or Save. Click Save. •Double-click to run it. When the tool opens click Yes to the disclaimer. Note: If you are prompted by Windows SmartScreen, click More info followed by Run anyway. •Click the Scan button. •When the scan has finished, it will save 2 logs in the same directory the tool was run from. Please either attach or PM me the following logs: Addition.txt FRST.txt Thanks Link to post Share on other sites More sharing options...
netrics Posted June 22, 2018 Author ID:1251852 Share Posted June 22, 2018 Hi the tool gives back "Failet to update (1)" and this probably because the server is very restricted in the outgoing connections ... we need to open the firewall for that tool. Can you give us the ip addresses we need to open? Link to post Share on other sites More sharing options...
Staff blender Posted June 22, 2018 Staff ID:1251853 Share Posted June 22, 2018 It won't run even though it cannot check for updates? Let me find out what address(es) you will need to temporarily allow. Link to post Share on other sites More sharing options...
netrics Posted June 22, 2018 Author ID:1251854 Share Posted June 22, 2018 (edited) Hi have you changed your ip's for updating/managing whatever malwarebytes needs to run properly? It looks like we cannot connect to these ip's here Edited June 22, 2018 by netrics Link to post Share on other sites More sharing options...
Staff blender Posted June 22, 2018 Staff ID:1251859 Share Posted June 22, 2018 This info page might help: Additional info I received from Ron here: "best to use a DNS entry if it's for proxy reasons. The update servers are on CDN and those IP change per region." Link to post Share on other sites More sharing options...
netrics Posted June 22, 2018 Author ID:1251864 Share Posted June 22, 2018 Tthanks - I will check with our networking team to verify on the firewall and to use dns. What about the farbar-recovery-tool? Is that included in those dsn entries? Link to post Share on other sites More sharing options...
Staff blender Posted June 22, 2018 Staff ID:1251871 Share Posted June 22, 2018 Not entirely sure yet what all the Farbar tool needs. Seems to be a cloudflare address. Not sure if this is even static. It should still run though even if it cannot check back home for an updated version so I am not sure I would bother with DNS entries for FRST as it would be a one-time connection to check if there is an updated version of the tool then it would not be needed any more. I am pretty sure though that the issue here is your server is unable to connect to our back-end when checking "goodware" file lists and such. I think once this is resolved, it'll be easier. We update the goodware lists many times/day & these lists are not downloaded to your machine like the definitions do. Instead they're in the cloud. A good portion of the goodware rules & badware rules are in the definitions downloaded locally to the machine & a good portion of it all is in the cloud because it is faster. Some of this is updated constantly so being able to connect fair quick is important. Link to post Share on other sites More sharing options...
netrics Posted June 22, 2018 Author ID:1251872 Share Posted June 22, 2018 OK - then let's wait until we are sure, that all outgoing connections from this server to your services are correctly configured on our firewall...... Link to post Share on other sites More sharing options...
Staff blender Posted June 22, 2018 Staff ID:1251873 Share Posted June 22, 2018 Sounds good. Link to post Share on other sites More sharing options...
netrics Posted June 22, 2018 Author ID:1251880 Share Posted June 22, 2018 I could finally run the farbar tool successfully. Just didn't realize, that it was only blocked during the update check. Here are the 2 textfiles Addition.txt FRST.txt Link to post Share on other sites More sharing options...

Staff blender Posted June 26, 2018 Staff ID:1252694 Share Posted June 26, 2018 Hi Netrics, Were you able to get your firewall & such set up so your MBAM can communicate OK? Let me know - if not, I'll have one of our techs pop in to have a look. Link to post Share on other sites More sharing options...
netrics Posted June 26, 2018 Author ID:1252716 Share Posted June 26, 2018 Hi - the firewall rules were adapted last friday to let the mentionend url's pass. Unfortunately, the beasvc.exe got blocked again yesterday afternoon around 4 pm (swiss time). Link to post Share on other sites More sharing options...
